What is a Heat Pump?

Showcasing 5 Projects

Heat Pump is a reverse refrigeration technology which extracts heat from the surrounding air and transfers it to the water circulating in its pipe. This hot water is stored in a hot water storage tank for later consumption

How Does It Work?

Heat Extraction:

A fan circulates air through the evaporator air coil that acts as a heat collector. The liquid refrigerant in the evaporator air coil absorbs the available heat from the ambient air.

Heat Intensification:

The compressor that receives the warmed refrigerant and intensifies the heat. The intensely hot refrigerant is then pumped into the heat exchanger.

Heat Transfer: 

The heat from the hot refrigerant flowing inside the heat exchanger is then transferred to the water. 

Why is a Heat Pump more energy-saving?

Unlike an electrical heater, a heat pump does not heat up the water through direct conduction. It uses the principle that a liquid’s temperature increases when pressure is applied. Energy required to apply this pressure is much lesser than that required by a heating coil. This results in a much more energy efficient way to obtain hot water. Energy savings can be as much as 75% compared to a traditional heating coil.

We at IBEX Solar are big supporters of this technology given its energy saving benefits. We offer both residential & commercial products. Here are some of our installations.
