Heat pump is a term commonly used for heat transferring or circulating devices, and machines like refrigerators, air conditioners and freezers. As opposed to the heat engine, heat pump converts mechanical energy into thermal energy. This task is mainly achieved with the help of fluids known as the ârefrigerantsâ. heat pump can be used to either heat the atmosphere or lower the temperatures, depending upon the type of output desired. However, a âfurnaceâ can be used only for heating. Furnaces cannot be considered as a cooling device.
