1. Introducing COOLNOMIX™

2. Contents Setting the Scene: Energy Consumption
Introduction to COOLNOMIX™
Case Studies
Q & A

3. Energy Consumption (1) Environmental pressures:
governments are increasingly legislating to reduce energy consumption
governments are exploring “carbon” taxation
consumers and business partners are beginning to discriminate based on environmental factors

4. Energy Consumption (2) Business pressures:
global competition continuously puts pressure on costs
Cooling is a significant contributor to energy consumption and costs

5. Energy Consumption1 (3) In Hong Kong’s total commercial sector:
air-conditioning accounts for nearly 26% of all electricity consumption
air-conditioning + refrigeration accounts for about 38% of all consumption
for comparison, lighting accounts for 13% of all consumption
In Hong Kong’s office sector:
air-conditioning accounts for 53% of all electricity consumption
lighting accounts for 14% of all consumption

6. 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

7. COOLNOMIX™ has been commercially available for more than 12 months and is delivering remarkable savings
an average 40% savings on air-conditioners
an average 30% savings on refrigeration systems

8. Some of our customers…

9. 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 objective
designed plant capacity exceeds peak demand to provide a margin of safety
COOLNOMIX ORS™ operates to reduce operational costs whilst:
improving temperature stability
prolonging the life of the compressor

10. COOLNOMIX™ employs dual temperature sensors, one for the space temperature the other for the cold supply
single sensor cooling systems operate “blind”
COOLNOMIX™’s second sensor provides feedback on compressor’s hydraulic work
Energy 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

11. ORS™ extends compressor life through reduced run-time
Temperature stability: dual sensors maintain temperatures within +/- 0.25˚C
ORS™ incorporates:
a priority on achieving and maintaining space set temperature
protection against frequent stop/start of the compressor
ORS™ extends compressor life through reduced run-time
ORS™ eliminates icing & dripping, the latter increasingly a focus of legislation

12. Retrofit Solution

13. 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

14. 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 system
savings begin immediately
zero maintenance requirements
COOLNOMIX™ retrofit deployment is not intrusive to the system:
COOLNOMIX™ only displaces the thermostat function
COOLNOMIX™ does not interfere with the system control functions

15. 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?

26. Q & A

28. 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
