AIR AND WATER HEAT PUMP Deluxe

The vapour compression cycle is the most common form of refrigeration, transferring heat from the area being cooled to a higher temperature region. Heat pumps use this effect to recover heat at a useful temperature for heating or other processes by upgrading low-grade 'free' heat — for example, from ambient air or water.
