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
