PARALLEL RACK SYSTEM APPLICATION MANUAL

INTRODUCTION TO PARALLEL COMPRESSOR SYSTEM APPLICATIONS

Mixed multiplexing is the application of a central compressor unit to operate refrigerated display cases, coolers and freezers with different evaporator temperatures or defrost schedules. The following four forms may be used: Specification Forms (Information for quotation) Instructions for filling out the Specification Form Power Consumption Comparison System Refrigeration Legend

Additional copies of these forms can be obtained from the IR/HUSSMANN Atlanta Engineering Department at (800) 879-5877 or (770) 291-9608. Refrigeration Systems - Information for Quotation Form The Information for Quotation form is useful as a reminder of the many often overlooked details of design, construction, and equipment options needed to provide a supermarket with the correct IR/HUSSMANN equipment. The use of this form both as a reminder and a communication tool between engineering and the customer will result in the most efficient use of time as the refrigeration systems legends are developed. Since there are several different ways compressor systems can be applied (especially on refrigeration systems with only two or three compressors in parallel), it helps to know in advance what the customer’s specifications and preferences are. For example, how does the customer feel regarding the following? Initial costs as opposed to energy costs. Splitting critical refrigerators (meat, ice cream) onto the different compressor units Discharge air temperatures (does the customer operate colder or warmer than our standard?) Margin of safety between load and compressor unit capacity Desirability of satellite units

Knowing the customer can save a lot of false starts and changes, provides more time to engineer equipment that best meets the customer’s needs. Refrigerators, Walk-ins, and Preparation Areas The requirement for accurate information on the customer’s design and preference for display cases, walk-in freezers, walk-in coolers, and preparation areas is imperative. It is important to accurately translate the customer’s generic descriptions of cases into complete IR/HUSSMANN nomenclature. Remember to consider such options as shelf lighting, glass fronts and varying discharge air temperatures because of the effect on the heat load required. Once the Information for Quotation Form and all information on display cases, walk-in freezers, walk-in coolers, and preparation areas are complete; the next step is to multiplex the store. Refrigeration Schedule/ Legend The refrigeration schedule, commonly referred to as the legend, will help in assembling the refrigeration circuits.

3

Filling in the Legend 1. Separate the medium and low temperature circuits. Circuits are considered low temperature when the

evaporating temperature is below 0° F. 2. Typically, one suction group is on one legend, however, there are designs where more than one suction group

may go on one legend. These may be low temp, medium temp or air conditioning or a mixture of the three. 2. Enter the size, model, and use of each circuit. It is helpful to list the circuits in the order that they will enter the

machine room and connect to the rack. Facing the electrical panel on the rack, the first circuit listed will be on the back farthest left and the last on the back farthest right. .

3. Refer to the refrigerator performance data and enter the appropriate discharge air (“Dis Air Tmp”) , evaporator temperatures (“Evp Tmp”), calculate the load for the line-up (Btu/hr * length), and enter the total in the column headed “Req’d Cap.” Refer to the unit cooler selection data and do the same for walk-ins and preparation areas. Varying cases or walk-ins multiplexed on the same line-up should be avoided if they have dissimilar defrost schedules.

4. All medium temperature HUSSMANN ONLY multi-deck cases loads should be reduced to 78% of their rated values when the ambient conditions are reduced to 70F/45%RH.

5. Consider any loads with much colder or warmer evaporating temperatures for possible application to a satellite unit or units (usually ice cream wide island cases and prep rooms). Be aware of any customer preference regarding satellite unit application. Next, total up the remaining systems. At this point, consider the following limitations and guidelines for mixed multiplexing.

6. Appropriate Return Gas Temperatures (RGT) for the compressors should be chosen based upon the temperature application of the System (e.g. LT / MT). The Hussmann recommendation for Low Temperature applications is 30ºF RGT and for Medium Temperature applications is 50ºF RGT.

7. Compressors will continue to be sized for approximately 80% - 95% load-to-capacity ratio. Limitations and Guidelines • A system load cannot exceed the available branch capacity. Occasionally this may necessitate splitting large

line-ups into more than one system, consider natural breaks in the fixture plans. Refer to the System Branch Capacities section, for available sizes.

• When selecting compressors, the suction temperature used is based on a two-degree temperature reduction for

medium temperature applications and a three-degree temperature reduction for low temperature applications from the lowest evaporator temperature in the case line-up. This allows for pressure drop due to the parasitic line loss in the piping.

• The number of branches cannot exceed the maximum allowable number for the compressor unit or remote

header defrost assemblies. This information is included in the Section labeled RACK AND RECEIVER ASSEMBLIES BY COMPRESSOR TYPE of this manual. If this condition exists, the next larger rack size will be utilized.

• The load should be between 80 to 95% of the compressor unit’s capacity. On one hand, a safety margin is

desirable to insure operation on hotter-than-design days, but on the other hand, too large a safety margin can result in performance problems such as short-cycling and inefficient operation.

• Generally, the refrigeration load of a system using Koolgas or hot gas defrost should not exceed 25% of the

total load of all the systems on the same compressor unit (loads operated by Satellites are part of the total). Since Koolgas defrost is accomplished with the heat extracted from other systems, this limitation is necessary to insure that sufficient heat will be available for a complete defrost, and that operating systems will not be penalized by inadequate pressure to feed the refrigerant. For applications exceeding this limit, consult the IR/HUSSMANN Application Engineering Department for assistance.

• When selecting compressors, mixing Copeland Reed and Copeland Discus compressors is possible. It is also

acceptable to mix Copeland Scroll and Copeland Reciprocating style compressors. Mixing Copeland Screw

4

compressors with Copeland Scrolls or Copeland Reciprocating should be avoided due to issues with the lubricant used. However, Carlyle compressors cannot be mixed with Copeland compressors. Mixing compressors that utilize two different types or viscosities of lubricants shall be avoided.

• When applying more than one compressor unit to a given temperature range, it is usually best to group the

systems mentally by ascending evaporator temperatures before selecting the units. In most instances, this will result in the most efficient and economical multiplexing because the warmer loads will be operated at a higher, more efficient suction pressure.

• With more than one compressor unit for medium temperature, separate the meat cases from the meat cooler(s),

if feasible, to maintain product safety in the event of mechanical failure. • Suction pressure controls should be applied to all critical temperature line-ups. Generally, if the load is not

critical, a branch can be operated within 5°F of the lowest rack evaporator temperature. • Avoid multiplexing systems, which would have all walk-ins and coolers on them. Their loads are easily

satisfied, and multiplexing could cause short cycling. At least 40% of the system load should be dedicated to cases, which have a more constant load on them.

• When multiplexing parallel racks, compressors should be sized so that each step-up in capacity is within the

range of 7 to 20%. This will avoid multiplexing compressors where a single compressor would have to handle the majority of the load, for if that compressor fails, there is no standby capacity. In addition, this practice will yield a more energy efficient design.

• Utilize satellite compressors, where possible, to reduce overall unit horsepower. • The combined total capacities of the Satellites should not exceed 40% of the main compressor unit’s capacity.

This is necessary to insure that the main compressor unit’s components are sized adequately for the additional loads. For applications exceeding this limit, consult the IR/HUSSMANN Application Engineering Department.

• The maximum number of on board satellites is two. • All components should be sized to the required load and NOT the available capacity. Once the component has

been matched to the required load, and a connection size matching the line size is available, select that kit. Otherwise, select the smallest available component connection that matches the required load.

• Walk-in cooler/freezer loads should be calculated using Koolcalc. The R-values for insulation walls used by

the customer should be verified. For example, R-30 should be used for MT and R-40 for LT. Furthermore, ambient conditions should be accounted for based on the location of the walk-in cooler/freezer. If the cooler is located in air-conditioned space, an ambient temperature of 70ºF should be selected instead of outside temperature.

Refrigeration Schedule or Store Legend There is a form called the “Refrigeration System Specification Form”, with this information the Application Engineer at IR/HUSSMANN can properly design and quote the refrigeration system. The Store Legend will be used to price and build the equipment. IR/HUSSMANN Engineering Staff will review it for completeness and accuracy prior to production. The following is a description of what information belongs in the various spaces and columns of the legend, starting with the top, reading left to right. General Information – Several pieces of information are important in order to properly complete the legend. This information is also required to properly advise the manufacturing facility of the customer’s information.

Cell F3 – Store Name of the Store Cell AH3 will be automatically filled in from F3. F4 – Location of Store Cell AH4 will be automatically filled in from F4. F5 – Quote No Cell(s) AH5 and AS9 will be automatically filled in from F5. H4 – Select from the drop down box the System Type, Custom System or Refrigeration Solutions System. NOTE – the RSS rack can only be equipped with Ingersoll-Rand Compressors. See RSS Specifications for further details and other approved components. U2 – Customer Main owner of the store chain. U3 – Contact Person to contact at the customer if there are questions U4 – Salesman (Salesman initiating quote request) U5 – Engineer (Your name) AO6 – Use the pull down menu to choose the return gas temperature for low temperature racks. AQ6 – Use the pull down menu to choose the return gas temperature for medium temperature racks. AP4 – Specify which specification was used (Customer (CU), Internal, (IN) RSS, etc) and the Date of that Specification. AP5 – When a Mechanical Notes Page is supplied to the production floor a YES should be entered in this cell. AP7 – Enter the Ambient Temperature for the city where the store will be located. Use the ASHRAE 1% Design rounded up to the nearest five. AP8 – Enter the Inside Temperature and Relative Humidity of the Store (typically 75°F/55%). Unless the customer specifies otherwise, Hussmann default is 70°F/45%. At these conditions, all Multi-deck MT cases should be multiplied by 78% to take advantage of the load reduction from the improved ambient conditions. AP9 – Enter the Altitude of the location of the Store. AP10 – Enter the Condensing Temperature of the system being designed. Standard practice dictates that if a system is Low Temp (LT) add 10° F to the Ambient Temperature. If the system is Medium Temp. (MT) add 15° F to the Ambient Temperature. If the System is Water Cooled see Atlanta Engineering. AP11 - Use the pull-down to choose and enter the Refrigerant. AP12 - Use the pull-down menu to choose the manufacturer and type of compressor. AP13 – Enter the voltage of the compressors to be used. AP14 – Enter the voltage of the control circuit. AP15 – Enter the voltage of the condenser. AS3 – Use the pull down menu to pick the manufacturer of the Solenoid Valves to be used AS4 – Use the pull down menu to pick the manufacturer of the Ball Valves to be used. AS5 – Use the pull down menu to pick the manufacturer of the Check Valves to be used. AS7 – Fill in the date of the original quote. This date once entered should not be changed. AS8 – Enter the initials of the Application Engineer completing the Legend. AS10 - Enter the file name of this legend. AX6 – Use the pull down menu to enter the number of satellite compressors. AX8 – Use the pull down menu to enter the number of suction groups. AX14 – Use the pull down menu to enter the Application Temperature. Store Design Conditions - The customer may specify the outside design, or it can be chosen from the appropriate ASHRAE tables (found in the ASHRAE Fundamentals Handbook). The information should be on the Hussmann/Atlanta Refrigeration Systems Specification Form as stated above. Refrigerated Display Cases, Walk-In Cooler, Walk-Ins Freezer, Prep Rooms - Required Capacity, Compressor Unit model - Refer to the legend and enter the data called for in the first eleven columns of the legend, adhering to the following guidelines: There are many ways to order the circuits on the rack, the main way is as follows:

o Group the systems on the rack in the order that they will enter the machine room and connect to the rack. Facing the electrical panel on the rack, the first circuit listed will be on the back farthest left and the last on the back farthest right. This will require a layout of the store and lining up the piping to eliminate cross over of piping from the rack to the case. Typically, when looking at the back of the rack each circuit from right to left will be the liquid line then suction line.

6

In the column marked “Unit Letter”, the main compressor units should be “A”, “B”, etc. Satellites should be lettered “S1”, S2”, etc. For a split suction rack, suction groups are typically named “AL” & “AR”. To describe the Satellite unit under the column headed “Compressor Unit Model”, write in “Satellite” for factory mounted, or the unit model number for remote.

Choosing Branches - Using the Branch Capacities section, size the suction branch and temperature control valves. Guidelines for selection are provided in Section 9 of this document. Enter the correct size into the proper column under the heading “VLV” (Column N). This will be referred to when choosing the IR/HUSSMANN nomenclature for each branch in the section corresponding to the selected unit. Condensers – Select condenser. After the condenser is selected, record the information on the Remote Condenser form at the top of the legend. The standard condenser manufacturer is Hussmann Coil Products (Krack). However, other coil manufacturers are available. Call IR/Hussmann Application Engineering Department for a list of manufacturers. Additional Forms Available - If the customer requests that case electrical requirements or refrigerant line sizing be provided, IR/Hussmann Application Engineering can provide this information on the legends. Line sizing is generally not provided until the job becomes an order. Pricing and Quotation - When the store legends are complete, the EXCEL spreadsheet will generate a list price for the refrigeration equipment. Compressor Warranty – Custom Racks without IR compressors carry a 1-year compressor warranty. However for many compressor models, an extended 4-year compressor warranty is available. To purchase this 4-year warranty on those models offering this option, the “Rack Quote” tab of the legend must have the 4 year extended warranty option and pricing as a line item. For Custom Racks with IR compressors, a standard 3-year warranty applies to the IR compressors. However, an extended warranty for the 4th and 5th year is available. To purchase this 4th year and 5th year warranty for IR compressors, the “Rack Quote” tab of the legend must have this option and pricing as a line item.

HUSSMANN PARALLEL COMPRESSOR SYSTEM COMPONENT SELECTION This section of the manual explains in detail the selection process necessary to assemble a complete parallel compressor system with a legend generated in a Microsoft EXCEL spreadsheet. The selection process begins with the compressor assemblies and progresses through all of the required and optional accessories. Compressors and Satellites must be selected to match the capacity of the particular refrigeration system. The compressor manufacturer and type, temperature range, and voltage should have already been determined and should appear on the Refrigeration System Information for Quotation, or customer specification. HUSSMANN PARALLEL COMPRESSOR SYSTEM NOMENCLATURE All IR/Hussmann parallel compressor systems require selection of a model nomenclature. The following chart explains assembly of the appropriate nomenclature CS 0 1 3 V L K | | | | | | | | | | | | | Voltage (K=208/3/60, M=460/3/60, P=575/3/60, U=380/3/50) | | | | | | | | | | | Temperature application {L =Low, M =Medium, H =High, D =Dual (Split Header), | | | | | T =Two Stage} | | | | | | | | | Refrigerant Type (S= R404A, P=507, V=R22, L=R402A, X=R401A) | | | | | | | Total number of compressors (Must be two digit i.e. 7 compressors = 07) | | | | | Number of suction groups | | | Number of satellite compressors. | Compressor System Designation{C = parallel compressor system, R = Refrigeration System Solution} COMPRESSOR ASSEMBLY NOMENCLATURE AND SELECTION PROCESS After selecting compressors based on required load to capacity ratio, the following process will complete the compressor unit section of the refrigeration legend. Reciprocating compressor (IR/HUSSMANN, Bitzer, Copeland and Carlyle) assemblies include the compressor, discharge and suction service valves, wire and other material for mounting and wiring. The legend will add an appropriately sized circuit breaker, contactor, oil float, and suction filter based on your selection of manufacturer. If the customer has a preference for vendor and type for contactors, enter this information in the compressor unit section. Use the pull down box menu to select the proper contactor type - Definite purpose contactors are standard, NEMA contactors may be selected as an option.

SECTION 2 - COPELAND DISCUS COMPRESSORS Copeland nomenclature has changed. Use the new model numbers only. Refer to the old model numbers as a cross-reference. There are two different product lines available when selecting Copeland reciprocating compressors, Discus and Reed. The major differences between the two are in the compressor size and the design of the intake and discharge valves. Discus and reed compressors may be mixed on the rack. The newer Discus compressors are typically 8% more efficient; they should be used where possible. Compressor capacity calculation is available on the legend for most models. See the Copeland software for additional models. TABLE 2A – COPELAND (STANDARD) DISCUS COMPRESSORS

NOTE: Current sensing relays are recommended for all 2D & 3D compressors to prevent false trips of the oil pressure control. Without current sensing relays (CSR), the oil pressure controls will de-energize the compressor control circuit if the internal overloads trip and do not reset before the oil pressure control alarm circuit times out. Use of the CSR on these compressors will prevent unnecessary service calls. Enter yes in the CSR box in the unit accessories area to have the legend automatically include the 25DD kit on 2D & 3D compressors.

The new optimized 3D and 4D compressors are specifically designed for medium temperature applications with lower RLA ratings than the standard models. For low or high temperature applications, continue to use the standard Discus models. We highly recommend using the new optimized compressors when applicable. TABLE 2B - COPELAND (STANDARD) DISCUS COMPRESSORS WITH UNLOADING Copeland 3D, 4D and 6D compressors are available with unloaders to provide additional stages of capacity reduction. Moduload unloading on 3D compressors is refrigerant specific and is not permitted on low temperature R-22 applications.

TABLE 2C - COPELAND DEMAND COOLING FOR STANDARD DISCUS COMPRESSORS All Copeland R-22 low temperature Discus compressors require a demand cooling application kit from the table below. This kit includes a Demand Cooling Module, liquid solenoid valve and appropriate piping. Demand Cooling prevents high head temperature associated with high heat of compression when utilizing R-22 at low temperature.

KIT DEMAND COOLING 01VZ 2D DEMAND COOLING 02VZ 3D DEMAND COOLING 03VZ 4D DEMAND COOLING 04VZ 6D DEMAND COOLING 67VR 4D DEMAND COOLING WITH SPECIAL WIRING FOR UNLOADERS 68VR 6D DEMAND COOLING WITH SPECIAL WIRING FOR UNLOADERS

NOTE: 3D Moduload unloading may not be applied to low temperature R-22. Blocked suction unloading on 4D and 6D compressors may be applied to all applications with R-22 low temperature operation requiring special wiring to load the compressor when the Demand Cooling module is energized. COPELAND ISD (Intelligent Store Discus) DISCUS COMPRESSORS ISD compressors are only to be used with CPC E2 rack controllers. The ISD compressors require that the E2 is equipped with a CPC Intelligent Store Discus Network Interface Board (CPC part number 637-3046). Also the firmware for the CPC controller must be revision level 2.07 or higher. However, revision level 2.21 or higher is recommended to ease commissioning. Only 2D, 3D and 4D compressors are available with the ISD control box. ISD compressors are identical to the equivalent non-ISD compressors in Tables 2A – 2C with the exception of factory installed and wired Intelligent Store Discus hardware and accessories. Following are the compressor protection features provided on all ISD compressors:

• High discharge pressure • Low suction pressure. • Discharge temperature. • Line-break motor protection (2D/3D). • Motor temperature protection (ISD replaces the solid-state module used on the 4D). • Low voltage. • Motor power interruption. • Welded contactor contacts. • Phase Loss. • Low oil pressure (Replaces the Sentronic+ TM oil pressure protection module). • Built-in compressor run proof detection. • Failsafe operation. Compressor and the provided protection, can function independent of the controller. • Manual or remote reset for oil pressure and high discharge temperature shutdown.

Following are the available options:

• Liquid injection for discharge temperature control (Replaces Demand Cooling Module on HCFC-22 low temperature models).

• Crankcase heater. • Capacity modulation.

All Bitzer /Copeland compressors require discharge temperature control through liquid injection or lubricant cooling. For most R404A/507 medium temperature applications, a 78LI liquid injection kit per compressor may be entered in the COMPRESSOR COOLING cell on the legend . It is not recommended to use liquid injection as the sole means of compressor lubricant cooling. External lubricant cooling may be accomplished through Bitzer Jet Kool, water-cooled or air-cooled heat exchangers. Please contact the IR/Hussmann Application Engineering department for assistance. With economized compressors, enter 50EC in the COMPRESSOR COOLING cell on the legend. All Bitzer/Copeland screws come with two stages of unloading.

TABLE 8C - SUCTION FILTER SHELLS Suction filters are standard per compressor and will be sized automatically on the legend when the letter abbreviation is entered next to SUCTION FILTER in the unit accessories section. Kits by vendor and compressor suction line size are shown in the table below. If no specific brand is specified by the Customer, Hussmann recommends the use of DANFOSS STEEL filters. However, it should be noted that brass suction filters will provide better corrosion protection. All filter shells use a common 48 cubic inch core EXCEPT for the Superior Brass. Each compressor is shipped with one suction filter core installed and one replacement shipped loose. See Compressor Section for proper application of those filters with “*” and “**” notation..

SECTION 11 - RACK AND RECEIVER ASSEMBLIES Selection of the rack frame assembly is dependent upon the number of compressors and circuits on the rack. Select the rack assembly nomenclature from Table 11A thru 11F below. Note that there are a maximum numbers of compressors and circuits per rack and receiver assembly. If you have more circuits than are allowed on a rack for the available number of compressors, you must choose the next larger frame size. For split suction racks, if you have an average of more than 3.5 circuits per compressor in any one suction group, you must select the next larger frame size. When one suction accumulator is mounted on the same rack you must use the next largest frame size. If two suction accumulators are mounted on the rack use a rack assembly that is two sizes larger. Increases in frame size because of suction accumulators may not be used for additional circuits due to the fact that the suction header does not increase in length. The rack assembly has a standard size 14”(20” for vertical) diameter receiver. If additional pump down capacity is required, an alternate can be selected from table 12A or 12B. NOTE 1: For 1 – 10 Carlyle 06E, Copeland 6D or IR 8 Cylinder compressors, only 1 extra compressor space is required. NOTE 2: Special requirements such as a rack-mounted electric defrost panel, inverters, suction accumulators, and other items may cause a frame to be longer than stated in these charts and others found below. If your system requires any of these items, OR if a frame size other than the standard length, width or height as shown below is required, consult IR/HUSSMANN Atlanta Design Engineering to determine the actual rack size. To note that a special frame will be required, please fill in the rack assembly nomenclature as XXSP, where the XX designates the number of compressors required. You will have to contact IR/Hussmann Design Engineering Department for the exact frame size.

For split suction systems use the percentage of the load for each suction group at it suction temperature and select a separator big enough to handle both, but not exceed 90%. Example R22 - 240MBH @ -25F and 600MBH @+20F, Only MT (+20) would require 927R. If we use 928R capacity @ -25F is 366MBH and @ +20 is 1081MBH. For –25F we use 240/469=52% and for +20F we use 600/1081=56% of the total oil separator capacity. 928R would be 108% loaded which is not acceptable, remember 90% is recommended maximum. 930R would be 66% loaded and would be the choice for this example.

SECTION 17 – HEAT RECLAIM, SPLIT CONDENSER AND ISOLATION BALL VALVES TABLE 17A - HEAT RECLAIM Approved heat reclaim valves for use with the RSS are the Sporlan up to a 2 1/8 and Mueller MBV for 2 5/8 and larger. The use of PE valves is not recommended due to their leakage rate. They have been removed from the manual. Please contact Engineering for kits if the Customer will not accept alternates and are willing to accept the leakage inherent in the PE valve design. The 4 psi pressure drop should be considered the standard unless specified otherwise by customer. Single heat reclaim is used for either air heat reclaim or water heat reclaim. Dual should be used when the rack will have both, air and water heat reclaim. For excessively long pipe runs consider using 2 psi pressure drop. Valves are rated for a 4psi pressure drop. For a 2psi drop decrease the capacity by 30%. See Section 22 for piping drawings.

TABLE 17D - SPLIT CONDENSER PIPING The following kits are to be selected when the condenser is to be split to reduce the flooding charge for winter head pressure control. These kits provide splitting valves (three way or motorized), pump out solenoid and metering orifice, and condenser drain line check valves. Mueller motorized ball valves are recommended since their slow operation reduces the sudden change in head pressure when coming in and out of split condenser. Select a kit based on rack load from the table below. Approved split condenser kits for the RSS are the Mueller MBVs. The use of PE valves is not recommended due to their leakage rate. They have been removed from the manual. Please contact Engineering for kits if the Customer will not accept alternates and are willing to accept the leakage inherent in the PE valve design. The 4 psi pressure drop should be considered the standard, unless specified otherwise by customer. For excessively long pipe runs consider using 2 psi pressure drop. Valves are rated for a 4psi pressure drop. For a 2psi drop decrease the capacity by 30%. See Section 22 for piping drawings.

If you have selected a split condenser kit in a previous step, select a two-valve kit for both the TO CONDENSER and from condenser. If a heat reclaim kit has been selected, add ball valves to the BV TO HR and BV FROM HR. A dual heat reclaim kit will require a dual ball valve kit. Use the discharge line sizing and liquid line sizing tables to size the lines to and from the condenser. All ball valves are full port.

Note 1: The above valves are for C&I and require very custom sizing criteria. Please consult the Design Engineering Group before using these valves. TABLE 18C -DISCHARGE DIFFERENTIAL VALVES For hot gas defrost, this kit includes a discharge pressure differential valve and discharge piping modification. A hot gas return header (HGR) may be used with a discharge differential valve. When installing components in the discharge line pressure drop can become an issue based on the number of components installed. Multiple heat reclaim and split condenser components applied on one system may produce excessive high side pressure drop, review vendor manufacturers data for proper application. If using those data points with italicized fonts, consult factory Global Engineering for additional guidance. 180 °F Discharge Temp. 95°F Condensing Temperature 3psi Pressure Drop

TABLE 18E – RECEIVER PRESSURE REGULATOR A receiver pressure-regulating valve should be selected whenever a discharge regulating valve or winter control is selected. Sizing is based on the discharge line size with one exception. When Koolgas defrost is used, the largest size kit should be selected. Differential valves will provide will maintain a differential between discharge and receiver pressure. Sporlan ORD’s are the preferred valve for situations where an adjustable valve is not required (i.e. Mezzanine Machine room with condenser located directly above).

TABLE 19C –SUCTION ACCUMULATORS The standard rack includes an oversize 4 1/8” suction header, which doubles as an accumulator. Refrigerant capacities for the accumulator header are shown in the first table below. Should a canister type accumulator be required, they can be selected based the tables for R404a and R22 below. Accumulators should be selected where the smallest capacity stage is above the minimum capacity and the capacity for that suction group is below the maximum shown. Selection of an accumulator where the capacity is close to the maximum will result in several psi of pressure drop across the accumulator at full load.
