Working Principle

Let’s Understand the Magic Behind Heat Pump (What is HP?)

As a layman, heat pump is a device which can be used to transfer heat from one medium to another. For example, when we take out chilled water bottle from our fridge and place it in the room, you will notice after some time that the chilled water has become hot and reached the room temperature without applying any external energy or force. Well this is nothing but application of Zeroth Law of Thermodynamics, where the heat will transfer from higher medium to lower medium until both system reaches equilibrium without any external energy source.

Working Principle

Our air source heat pump uses eco-friendly refrigerant R410A, as a lower medium to extract Heat from the atmospheric air temperature as low as -30° Celsius to heat water. Once the small amount of free heat is extracted from the air by refrigerant, the warm gas is passed through compressor to further raise its temperature by applying high pressure so that the heat from the refrigerant can be transferred to heat water using an efficient Heat Exchanger.

This process allows our Air Source Heat Pump to deliver up to 5 kW of Thermal energy while consuming only 1 kW of electrical energy. Following diagram elaborates working principal of air source heat pump.
