Introducing COOLNOMIX™

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

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

Energy Consumption (2) Business pressures: global competition continuously puts pressure on costs Cooling 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 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 Note 1: Hong Kong End-use Data 2011 (EMSD, Sep 2013)

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 savings an average 40% savings on air-conditioners an 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 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

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

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

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 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

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?

Value-based Pricing Assume 7.5kwh air-conditioner 1kWh = US$0.15 air-conditioner operates 7 days/week, 9 hours/day air-conditioner is needed 8 months/year normal duty cycle of compressor is 70% energy savings are 30% Annual savings = US$517 Ten year savings = >US$5,170 Current pricing policy targets pay-back on investment within the first 12 months; minimum end-user price = US$384

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
