Ecogen Energy System is based on a technology acquired from Australia, the results of many years of extensive research and development carried out at the University of Melbourne, Australia.

As energy costs are becoming expensive, the demand for efficient hot water generation system is getting increasingly popular. Today, the Ecogen Energy System is manufactured and marketed under a joint-venture agreement in Malaysia by Linear to cater for the markets in Asia and Middle East.

Co-generating Hot Water & Free Cooling

Ecogen Energy System works on the same principle as an air-conditioner in the reversed cycle.

The compressor compresses the refrigerant vapour and directs the hot compressed vapor refrigerant to the copper tube coiled round the water storage tank. This makes the coil to act as the condenser and gives out heat energy that is transferred to the water in the storage tank by way of conduction.

The cooled liquid refrigerant is then passed through the liquid receiver to filter the liquid content from the refrigerant vapour. The filtered refrigerant is expanded through the expansion valve and is passed through the evaporator inside or outside the unit where heat from the surrounding is absorbed into the vapour. The refrigerant then flow back to the compressor to complete one cycle of process.

This heating process will keep running until water temperature reaches 57 ±3°. P&T valve is used to ensure the pressure and temperature of the storage water does not exceed the set limits.

In residences, food chains, launderettes, hair salons, etc, the Ecogen Energy System in single module up to three modules can be used to supply hot water for consumption of 6 persons to 15 persons for shower, washing and cleaning.

In commercial applications, where there is a consistently high demand of hot water such as hotels, hospitals, dormitories, sports clubs, the Ecogen Energy System in multiple modules can be used to replace conventional gas-fired/oil-fired boilers or electric heaters from 30 rooms onwards.

While hot water is generated with much improved efficiency resulting from the COP of the heat pump refrigerant cycle, the 'free cooling' produced by the evaporator in the heat pump unit can be used to ventilate areas like laundry room, patios, garage, workshop, kitchen, motor room, etc.

Ecogen Energy System is synonymous with cogeneration, simultaneously producing hot water and cool air.

1. Modular Design

Ecogen Energy System comes in different module sizes.

The Series RC with a 1.1kW compressor is completely self-contained and is suitable for the residential, food chain, launderette, hair salon, etc.

The Series CC has a 1.8kW compressor with the evaporator separately mounted designed for multiple-module configuration especially for the commercial segment like hotels, hospitals, dormitories and sports & country clubs.

Both Series RC and CC have a 340 liter storage capacity for one single module.

2. Very Low Operating Cost

It uses only approximately 30% the power needed by electric heater to heat the same amount of water. It merely 'pumps' the heat from one location to another.

3. Eliminates Conventional Fuel Boiler Cost

It completely eliminates all costs associated with boiler system such as chimneys, ducting, fans, fire-safety system and fuel piping system.

4. Eliminates Hazards

It completely eliminates the needs to handle any hazardous fuels.

5. Low Maintainance Cost
Compared to conventional fuel boiler, the maintenance cost is minimal. Ecogen Energy System only requires yearly anode checks and cleaning of air vent.

6. Free Cooling

Ductable chilled fresh air at about 10 °C less than the ambient can be channelled to the desired location for 'spot cooling' or ventilate an enclosed area. Hence, downsizing the air-conditioning equipment is also possible.

7. Attractive Payback Period

Compared to the electric heater, the extra investment spent on the Ecogen Energy System can be recovered in a short period of 20 months. Thanks to the COP of the heat pump refrigerant cycle.

8. No Contamination

Most heat pump water heaters have their hot and aggressive vapor refrigerant tube immersed in the storage water. This poses the danger of the storage water to be contaminated by the refrigerant whether be they R134a or R22 which all contain the hazardous chemical Asphyxiate.

BOC Refrigerant Technical Guide states the following precautions in use.

Wear safety goggles, leather/plastic protective gloves, overalls and safety shoes when    handling cylinders.
Use only in well ventilated areas. Ventilate to prevent accumulation of high    concentrations of R134a and ensures the oxygen level in the air is greater than 18%.

Ecogen Energy System does not pose any threat of contamination to the storage water in the event that the refrigerant coil is NOT immersed in the water.

 Working Principles

The Ecogen Air Link Water Heater can be installed anywhere where hot water needed. The Air Link water tank is linked to the split air-conditioner system which comprises a condenser, expansion valve, evaporator and compressor. Thus the whole system can be explained by using two loop.

Firstly, the refrigerant loop which incorporates the split air-conditioner system. Heat is absorbed from the surrounding environment by the evaporator to heat the refrigerant. Then, the refrigerant evaporates into the compressor where it is compressed and superheated. Then, the superheated compressed refrigerant passage through the copper tube coiled round the Air Link water tank. This makes the coil act as the condenser and gives out heat energy that is transferred to the water in the tank by conduction. The refrigerant gas then passes through the condenser where it is further condensed into liquid. Upon passage through the expansion valve, the refrigerant is super-cooled and returned to the evaporating unit to complete the refrigerant loop.

Secondly, there is the water flow loop. This loop stretches from the inlet of cold water from the water source to the outlet of hot water for the bathroom, kitchen and laundry. This loop is related to the refrigerant loop where the process of heat energy transfer from the superheated refrigerant to the water takes place
