How Air to Water Heat Pumps Work
Air-to-water heat pumps work by utilizing the principles of refrigeration. The process begins with the outdoor unit, which contains a compressor and a fan. The compressor pressurizes the refrigerant, causing it to become hot. The fan then blows air over the hot refrigerant, transferring the heat from the refrigerant to the outdoor air.
The hot refrigerant then travels through a series of pipes to the indoor unit, which contains another fan and a heat exchanger. The fan blows indoor air over the heat exchanger, transferring the heat from the refrigerant to the indoor air. The now-cooled refrigerant returns to the outdoor unit, where it is compressed again and the cycle continues.
Benefits of Air-to-Water Heat Pumps
