19. Low Ambient Cooling Enhancement


�� RELQ-T series include a feature for Low Ambient Cooling.�� The function enhances RELQ-T series as follows:

• Allowsoperationto−4°FDB(−20°CDB)ambienttemperatureincoolingmode.(Normallimitis23°FDB(−5°CDB).) • Operationbelow23°FDB(−5°CDB)requirestheadditionofwindcoversontotheoutdoorunit.*

Application Rules: • Totalconnectionindexofeachsystemislimitedto50-130%whenheightdifferenceis0-194ft.(0-50m),80-130%when194-

295 ft. (50-90 m).• All units on the system must be connected to a Branch Selector Box. Low Ambient Cooling is available on indoor units connected

to either single-port (BSQ_TVJ) or Flex Series (BSF_Q54TVJ) multi-port branch selector boxes *1. Both single port and multi port boxes can be used in the same system, however indoor units connected to Standard Series (BS_Q54TVJ) multi port branch selector boxes will operate as standard without Low Ambient Cooling functionality.

• FunctionisengagedbyafieldsettingontheoutdoorunittoenableLowambientcooling.*1AdipswitchsettingisnecessaryontheSingle Branch Selector Boxes BSQ-T series serving the indoor units NOT subject to Low Ambient Cooling requirements. For Flex series (BSF-Q54TVJ) Multi-port Branch Selector Boxes, all indoor units connected to each port are subject to Low Ambient Cooling modeifthefieldsettingontheoutdoorunitiseffective.

• Duringoperationbelow23°FDB(−5°CDB),theavailablecoolingcapacitydecreasesasfollows: 14°FDB(−10°CDB)-Reducesto80%ofnominal. 5°FDB(−15°CDB)-Reducesto65%ofnominal. −4°FDB(−20°CDB)-Reducesto60%ofnominal.*1

• While system is operating in low ambient cooling mode, Branch selector boxes supporting low ambient cooling could experience operation sound levels of up to 3 dB(A) higher than maximum. It is recommended to locate units away from zones sensitive to sound levels. *1

• Allowableheightdifferencebetweenoutdoorandindoorunits(whenoutdoorunitisbelow)islimitedto130ft.(40m).(Normallimitis 195 ft. (60 m).)

22. Selection Procedure22.1 Selection Procedure22.1.1 Flowchart

Provisionally select outdoor unit type and size based on limitation of connection ratio

Correct for cooling & heating capacity of the outdoor unit by the following items

VRV system selection is complete.

Confirm that the number of indoor units connected to the outdoor unit is within limitation.

Corrected capacity of the outdoor unit ≥ Required total heat load to the outdoor unit

* In case of selection based on Total Heat Load and Sensible Heat Load, select indoor units which satisfy not only the Total Heat Load but also the Sensible Heat Load of each room. The sensible heat capacity of indoor units is to be corrected for indoor air temperature. If the design temperature of indoor air falls between temperatures listed in table, calculate sensible heat capacity by using the bypass factor calculated by interpolation for each indoor air temperature.

(2) Provisionally select an outdoor unit based on the total CI of the indoor units

The connection ratio of RELQ-TA shall be between 70% and 130%.As the total CI of the indoor units is 234, outdoor units from 16 ton to 20 ton are connectable.Start from 16 ton which is the smallest outdoor unit.

(3) Confirm that the number of the connected indoor units is within the limitation.

The number of the connected indoor units = 8

24. Caution for Refrigerant Leaks24.1 Introduction

The installer and system specialist shall secure safety against leakage according to local regulations or standards. The following standards may be applicable if local regulations are not available.

The VRV System, like other air conditioning systems, uses R410A as refrigerant. R410A itself is an entirely safe non-toxic, non-combustible refrigerant.Neverthelesscaremustbetakentoensurethatairconditioningfacilitiesareinstalledinaroomwhichissufficientlylarge.Thisassuresthat the maximum concentration level of refrigerant gas is not exceeded, in the unlikely event of major leak in the system and this in accordance to the local applicable regulations and standards.

Maximum concentration levelThe maximum charge of refrigerant and the calculation of the maximum concentration of refrigerant is directly related to the humanly occupied space in to which it could leak.The unit of measurement of the concentration is lbs./ft.³ (kg/m³) (the weight in Ibs. (kg) of the refrigerant gas in 1 ft.³ (1 m³) volume of the occupied space).Compliance to the local applicable regulations and standards for the maximum allowable concentration level is required.

Direction of therefrigerant flow

Room where refrigerant leak has occurred(outflow of all the refrigerant from the system)

Pay special attention to places, such as basements, etc. where refrigerant could stay, since refrigerant is heavier than air.

72


24.2 Procedure for Checking Maximum Concentration

Check the maximum concentration level in accordance with steps 1 to 4 below and take whatever action is necessary to comply.Step1: Calculate the amount of refrigerant (lbs. (kg)) charged to each system separately.

Amount of refrigerant in a single unitsystem (amount of refrigerant withwhich the system is charged beforeleaving the factory)

+

Additional charging amount (amountof refrigerant added locally inaccordance with the length or diameterof the refrigerant piping)

= Total amount of refrigerant (lbs. (kg))in the system

Note:Where a single refrigerant facility is divided into 2 entirely independent refrigerant systems then use the amount of refrigerant with which each separate system is charged.

Step 2: Calculate the smallest room volume (ft.³(m³)) In case like the following, calculate the volume of (a), (b) as a single room or as the smallest room. (a) Where there are no smaller room divisions.

(b)Wherethereisaroomdivisionbutthereisanopeningbetweentheroomssufficientlylargetopermitafreeflowofairbackandforth.

Opening betweenrooms

Partition

(Where there is an opening without a door or where there are openings above and below the door which are each equivalent in size to 0.15%ormoreofthefloorarea.)

(c) Where there is a gas leak detection alarm device linked to a mechanical ventilator in the smallest room then the next smallest room will become the measurement target.

73


Step 3: Calculating the refrigerant density using the results of the calculations in steps 1 and 2 above.

Total volume of refrigerant in therefrigerant system

≤ Maximum concentration level (lbs./ft.3(kg/m3))Size (ft.3(m3)) of the smallest room in whichthere is an indoor unit installed

If the result of the above calculation exceeds the maximum concentration level then make similar calculations for the second then third smallest room and so until the result falls short of the maximum concentration.

Step 4: Dealing with the situations where the result exceeds the maximum concentration level. Where the installation of a facility results in a concentration in excess of the maximum concentration level then it will be necessary to

revise the system. Please consult your Daikin supplier.
