Introducing COOLNOMIX™
Contents
Setting the Scene: Energy ConsumptionIntroduction to COOLNOMIX™Case StudiesQ & A
Energy Consumption (1)
Environmental pressures:governments are increasingly legislating to
reduce energy consumptiongovernments are exploring “carbon” taxationconsumers and business partners are
beginning to discriminate based on environmental factors
Energy Consumption (2)
Business pressures:global competition continuously puts
pressure on costsCooling is a significant contributor to
energy consumption and costs
Energy Consumption1 (3)
In Hong Kong’s total commercial sector:air-conditioning accounts for nearly 26% of
all electricity consumptionair-conditioning + refrigeration accounts for
about 38% of all consumption for comparison, lighting accounts for 13% of
all consumptionIn Hong Kong’s office sector:
air-conditioning accounts for 53% of all electricity consumption
lighting accounts for 14% of all consumption

COOLNOMIX™ is a patent pending product range of Agile8
Agile8’s objective is to reduce worldwide running costs of direct refrigerant-based
cooling systems1 by 30%
Retrofit solution for fixed temperature, commercial environments
Note 1: COOLNOMIX™ is for systems where the air is cooled directly by the refrigerant evaporators; not when the refrigerant evaporators are used to cool water which is then used to cool the air
COOLNOMIX™ has been commercially available for more than 12 months and is delivering remarkable savingsan average 40% savings on air-conditionersan average 30% savings on refrigeration
systems
Some of our customers…
Energy savings are achieved by patent pending COOLNOMIX ORS™ORS™ optimizes the run-time of the cooling
system compressor, responsible for ~95% of energy consumption
COOLNOMIX ORS™ leverages a key cooling plant design objectivedesigned plant capacity exceeds peak
demand to provide a margin of safetyCOOLNOMIX ORS™ operates to reduce
operational costs whilst: improving temperature stabilityprolonging the life of the compressor
COOLNOMIX™ employs dual temperature sensors, one for the space temperature the other for the cold supplysingle sensor cooling systems operate
“blind”COOLNOMIX™’s second sensor provides
feedback on compressor’s hydraulic workEnergy savings:
cold supply temperature used as a proxy for deciding when the compressor has completed its work
compressor then switched off until further refrigerant compression is needed
Temperature stability: dual sensors maintain temperatures within +/- 0.25˚C
ORS™ incorporates: a priority on achieving and maintaining space
set temperatureprotection against frequent stop/start of the
compressorORS™ extends compressor life through
reduced run-timeORS™ eliminates icing & dripping, the
latter increasingly a focus of legislation
Retrofit Solution
Retrofit Applications (1)
COOLNOMIX™ units can be deployed for savings on:any direct refrigerant-based air-conditioner
or refrigerator, including split-type air-conditioners window-type air-conditioners package type air-conditioners VRV/VRF/Inverter type air-conditioners ducted air-conditioning systems industrial size refrigerators
cooling systems operating between 0oC and 31oC
Retrofit Applications (2)
COOLNOMIX™ retrofit units are suitable for commercial premises deployments
One COOLNOMIX™ unit is required per cooling system thermostat
Retrofitting is about one hour per systemsavings begin immediatelyzero maintenance requirements
COOLNOMIX™ retrofit deployment is not intrusive to the system:COOLNOMIX™ only displaces the thermostat
functionCOOLNOMIX™ does not interfere with the
system control functions
Frequently Asked Questions
Doesn’t the increased stop/start of the compressor reduce its life?protection against frequent stop/start of the
compressor – maximum # of stop/start per hour is ~6
the reduced compressor run-time prolongs its life!
Doesn’t fitting COOLNOMIX™ invalidate the warranty?only displaces the thermostat function &
does not interfere with the control system in any event, is the warranty worth losing
30%+ savings?

Q & A
Competitive Analysis
COOLNOMIX™ is the only third-generation technology in this space of which we are aware
Earlier generations, some of which we had an involvement in, deliver some savings using a single temperature sensor
These technologies suffer from a number of problems, the most significant being that space temperature drifts upwards
