TRANSFORMING WASTEFUL TO USEFUL ENERGY

HEAT RECOVERY HOT WATER SYSTEM

WHAT IT IS

Waste heat is a by-product of the air conditioning system. It is thrown away wastefully. But instead of rejecting the heat into the environment, we can recover the waste heat and transfer the energy into the water.

 

The chart compares the different methods of heating water using different energy sources. Clearly, using waste heat is unbeatable. Water is heated literally for “free”.

 

So instead of burning precious fossil fuels to heat 100-meter cube of hot water daily, the heat recovery system can save 1.3 million kWh worth of energy and at 2008 prices, costing about S$260,000 per year

HOW IT WORKS

All the conventional air-conditioner regardless of water-cooled or air-cooled reject the heat into atmosphere.

 

The Natflow's Heat Recovery Hot Water System is tailor-made water heating system to hijack the refrigerant from the condenser and by pass it into tube-in-tube heat exchanger. While the refrigerant is going through the heat exchanger, cold water is concurrently being passed through  to be heated. Then the heated water is stored in water tank and ready to be served to hot water users.

WHY IT IS SPECIAL

Our unique Heat Recovery system addresses 2 major concerns that most of other heating systems cannot solve:

 

Risk of Water Contamination

The heat exchanger's double-walled tube design incorporates a safety circuit that allows to detect refrigerant leak even before the refrigerant contaminate the water. An electrical signal is then sent to alert the user of the leak. This TUV-approved feature is one of its kind and extends to the entire heat exchanger surfaces.

 

Risk of Scaling

The water molecule flow through the heat exchanger only once and within minutes is heated to the desired temperature. This contact time is too short for any significant scale formation. Should in extreme cases de-scaling becomes necessary, the heat exchanger can be cleaned quickly and economically using the special connections points provided. It is not necessary to disconnect the water or refrigerant circuits.
