RELIEF COOLING
TEMPLATE
Nomograph for the rapid calculating of direct evaporative
cooling results. The two templates show the nomographic
procedures for comfort cooling maintaining indoor dry - bulb
8o F below outdoor air, and for relief cooling with a 6oF
differential.
In both cases comfort sensations depend heavily upon air
velocities. Adapted from early ASHRAE effective
Temperature nomographs for comfort determination.
RELIEF COOLING
TEMPLATE
Calculating Rough Direct Evaporative Cooling Comfort Levels.
1. Select ODB and WB from local air conditioning design data.
ODB is Outdoor Dry – Bulb temperature.
WB is Outdoor Wet – Bulb temperature.
2. Draw Outdoor Condition Line from ODB to WB
3. Select Cooler Saturating Efficiency column. Where it Crosses Outdoor Condition Line.
Read WAE, the washed – air room – entering temperature.
4. Select washed – air Indoor temperature gain, usually 6o to 10o F, and WAE, and draw a line to WAE, exhaust temperature.
5. Locate WAIA, the washed – air Indoor average temperature, midway between WAE and WAX.
RELIEF COOLING
TEMPLATE
6. Draw horizontal line left from WAIA to find IDB, the average indoor
dry – bulb temperature.
7. Select IWB (Not shown), usually 2o F above WB. It is the estimated
indoor wet – bulb temperature.
8. Draw indoor Condition Line from IDB to IWB.
9. Select an estimated indoor average Air Velocity Line in grid at left,
usually between 100 and 400 fpm.
10. Read indoor comfort level in Effective Temperature degrees, where
Indoor Condition Line crosses indoor Air Velocity Line. Read
estimated present of comfortable people at upper left.
“Wind Chill” Effect as per ASHRAE
Comfort Chart Adaption to other Conditions
Aside from its fixed dew point limits, the
ASHRAE Comfort Zone adjusts for faster indoor air
velocities and for human acclimatization to conditions.
First, the zone expands to tolerate higher dry bulbs;
its right – hand border moves to the right as circulation rates
increase to about 350 fpm (1 – 8 m /s). Assuming the taller
zone noted above, it allows some conventional direct
evaporative cooling to achieve official comfort.

Second, other extension areas appear on the zone right border to represent comfort felt
by persons acclimated by 7 to 10 days’ exposure to moderate discomfort. After initial
habituation, mere one – day per week re-exposure maintains the benefits.
Specifically, the right-side extension approximates 2o F (1.1oC) ET*, presumably
additive to velocity – based extensions.

“EasyStreet’s goal is to provide services in a facility that is reliable, safe and secure, versatile, and responsible to the
environment. We want to achieve a data center design with the ideal balance between energy efficiency, affordability and
performance. This data center is an important step toward our goal to be Oregon’s greenest IT services provider.” –
EasyStreet President and CEO, Rich Bader
EasyStreet Online Services began in 1995 and is Oregon’s largest independent provider of corporate IT services. Services
provided include server colocation, cloud computing, managed hosting, and high-speed connectivity. EasyStreet is locally
owned and managed (headquartered in Beaverton) and has recently opened a new commercial data center which features
breakthrough technologies to reduce energy consumption and increase sustainability. Data centers have traditionally been
highly inefficient, consuming vast amounts of electricity. EasyStreet’s data center challenges this tradition and is striving
to serve as a model for IT centers throughout the state.
The following is an outline of some of the innovative technology employed to increase efficiency and overall sustainability.
According to CEO Rich Bader, these state-of-the-art technologies will allow EasyStreet’s
new data center to save 1,532,634 kilowatt hours per year. This is equivalent to the power
consumed by 153 households in one year or eight trainloads of coal annually. Perhaps one
of the most remarkable aspects of EasyStreet’s initiatives is that it will not be charging
customers a ‘green surcharge’ to offset the higher costs associated with implementing
these green features. The efficiencies gained by the design spare customers the steep rise
in power costs associated with other data centers. This is possible because power costs
rise slower when energy efficiency is higher.
In addition to this high tech equipment, EasyStreet also has a hybrid and all-electric
charging station for customers and employees. They also support employee participation
in a city-wide solar effort through hosting on-site solar workshops, approving staff away
time for home energy audits, and approving continuing education. EasyStreet has led the
way for sustainable business practices, successfully illustrating how reducing your
environmental footprint and making a profit are not incompatible.

FOR IMMEDIATE RELEASE
Denver, CO August 23, 2011 - Carrier West has selected AMAX IDEC economizers for
its new cooling efficiency program for multiple Colorado school systems. Carrier West
and Innovative Mechanical Systems (IMS) selected AMAX to supply IDEC (Indirect
Direct Evaporative Cooling) economizers to provide pre-cooling for Energy Recovery
Ventilation (ERV) units on Coloradoschool energy efficiency projects. The first systems
will be installed in the Akron, Colorado school system by IMS, a mechanical designbuild
firm based in Louisville, Colorado.
AMAX Indirect/Direct Cooling (IDEC) units offer the energy saving benefits of
advanced, multi-stage evaporative cooling. IDEC can be used to replace or supplement
"Direct Exchange" (DX) air conditioning in certain climate geographies. "Colorado
schools are seeking to cool indoor environments for their students and staff, while
reducing energy costs." said Corey Trease, Commercial Sales Engineer for Carrier
West, "When we went in search of a more efficient evaporative cooling solution, AMAX
technology was a great fit - especially in the Colorado climate".
IDEC units offer an inexpensive retrofit option that reduces DX compressor run-time
and extends equipment life. Equipment payback is often less than five years. AMAX
supplies 100% outdoor air. As a result, the more fresh air a building requires and the
hotter the outdoor temperature, the more energy savings AMAX delivers. AMAX is an
ideal solution for schools, medical facilities, casinos and data centers. Switching to
IDEC cooling provided by AMAX can save up to 75% of facility cooling costs.
Improved indoor air quality is another significant benefit. Numerous studies show
that advanced evaporative cooling, known as air washing, delivers 100% fresh air
resulting in improved indoor air quality (IAQ) and significant reduction in particulate
matter, CO2 and formaldehyde. AMAX IDEC coolers are manufactured by Ambassador
Coolers Ltd, of New Delhi, India for AMAX USA. www.AMAX.us.com.

CASE STUDY APSRTC
DRIVERS RETIRING ROOM
APSRTC was first established in June 1932 as NSR-RTD (Nizam State Rail & Road Transport Department), a wing of Nizam State Railway in the erstwhile Hyderabad State, with 27 buses and 166 employees. During the past 77 years, it has registered a steady growth from 27 to 21,606 buses with 767 bus stations, 202 Depots and 1, 880 bus shelters.
The Corporation's buses cover 75.93 Lakhs KMs. and carry 135.99 lakhs people to their destinations every day. They connect 24,336 villages to all major towns and cities in A.P which constitutes 95% of Road Transport. APSRTC operates to City and Mofussil areas. The Corporation's buses also ply to important towns and cities in the neighboring States of Tamilnadu, Karnataka, Maharashtra, Goa, Orissa and Chattisgarh.
Andhra Pradesh State Road Transport Corporation has been leading by an example. It has a number of firsts to its credit in India:- • First to nationalize passenger Road Transport Services in the country-1932. • First to introduce long distance night express services. First to introduce A/C
Sleeper, Hi-tech, Metro Liner, Inter-City Services and Metro Express. • First to introduce Depot computerisation-1986. All the 202 Depots in the State are
Computerized.
1st to introduce Green air conditioning system in August, 2008. AMAX, a II Stage Smart Cooling System, consisting of an air conditioning coil, in built cooling tower
etc 5 Nos, were used for the APSRTC Crew Room catering for 750 people in 12 crew rooms in 13,000 sq ft with 88,000 CFM quantity of air with a cooling efficiency of 115% or with a design to give us 2°C below wet bulb at Gowliguda, Hyderabad.
It has been designed, supplied and installed by M/s United Engineering Corporation, Secunderabad. www.smartcoolindia.com Varying temperatures during different times of the day from March to August 2009,were taken & the temp attained at the grill in all the crew rooms was between 23 - 25°C, even when the maximum outside temp was 42°C.
The total power load connected in all the AMAX machines was 72 HP / 54 KW and the energy consumption was 54 units per hour.
The equivalent in conventional air conditioning would have been app. 150 tons or 195 KW. The savings for our dept /state app. 141 KW of power hourly. We need this area to be air
conditioned round the clock as the drivers come through the day. Hence a saving of 3384 KW daily or RS 23,688/@ Rs 7/per unit.
HENCE a yearly saving of RS 86, 46,120/only

The other benefits we found were that we had to use a lower capacity Transformer, deposit with electricity dept & cabling for the same, smaller generator & hence lesser running cost/ AMC, smaller panel board etc.
The AMC for the green building air conditioning system also was very less vs. A/c of Rs.2,70,000/- per year. This is over & above the benefit of giving our crew fresh, cool, clean & Healthy air /A better indoor air quality for them to work better, as we did not re-cycle the stale air.
This installation was possible due to the keen interest and confidence evinced in the product by the Electrical Engineers and CMD. Since APSRTC always has the history of switching over to new, innovative and energy efficient technology/measures as can be seen from the number of ‘FIRSTS' to their credit.
While the management of APSRTC is extremely satisfied with the working of the units, their staff are a happy lot enjoying the cool ambience and owe their gratitude to the management for providing them healthy comfortable place. M.Chakradhar
