The Working Principle Heat Pumps | Green Energy Solutions
The Working principle. Heat energy naturally transfers from warmer places to colder spaces. However, a heat pump can reverse this process, by absorbing heat from a cold space and releasing it to a warmer one. Heat is not conserved in this process and requires some amount of external energy, such as electricity.
