Heat Pump

A heat pump water heater (HPWH) operates on a simple yet efficient principle: it extracts heat from the surrounding air and uses it to heat water in a storage tank. Unlike traditional electric resistance water heaters, which generate heat directly, HPWHs transfer heat from one place to another, making them far more energy-efficient. This process involves a heat pump that uses a refrigerant to absorb heat from the air, which is then compressed to increase its temperature. The heated refrigerant releases its heat to the water in the tank through a heat exchanger. This method of heating water consumes less electricity, resulting in lower energy bills and reduced environmental impact. Installation of HPWHs is versatile, as they can be placed in various locations, such as basements, garages, or utility rooms, provided there is adequate space for air circulation. Overall, HPWHs offer a greener and more cost-effective solution for heating water in residential and commercial settings.

Working Principle -Heat Pump Water Heater:

The heat pump makes use of a refrigerant for its operation. The low temperature refrigerant absorbs free heat from the atmospheric air in the evaporator is compressed by a highly efficient electrical compressor to a high- temperature and high-pressure vapour refrigerant.

This vapour is then passed through a heat exchanger (condenser) to transfer the heat to the water in the storage tank to produce hot water. The refrigerant then passes through an expansion valve and it goes back to the evaporator for absorbing the free heat from the atmospheric air again and the cycle is repeated.
