How Heat Pumps Work
The substance that allows a heat pump to work is refrigerant. A refrigerant is a substance or mixture, usually a fluid, that has properties allowing it to transition from a liquid to a gas and back again (or various combinations of the two). Another important property of a refrigerant is that it boils at low temperatures, such as room temperature air or colder.
Refrigerant starts out inside a compressor, which is also the “pump” part of the ductless heat pump, in the outdoor unit. This compressor pumps the refrigerant between two coils. Heat pumps work by energy transfer; therefore one coil is always absorbing heat while the other is releasing heat.
The system’s goal is to move heat (energy) into your home from the outside air. Valves cause pressure in the outdoor unit to increase, causing the refrigerant in the coil outside to get very cold, even colder than the surrounding air. This cold refrigerant absorbs heat from the slightly warmer outside air. The warmed refrigerant is then pumped inside. When it enters the coil in the indoor unit, a fan blows air across warm refrigerant in the coil and that warm air is blown into your home.
The system’s goal is to remove heat (energy) from inside your home. Valves cause pressure in the indoor unit to increase, causing the refrigerant in the coil to get cold. A fan blows air across the cold refrigerant in the coil and cools your home. Warm air from inside your home is absorbed by the cool refrigerant and pumped outside to the outdoor unit where it is released into the air.
