A ductless heat pump, sometimes called a mini-split air conditioner or a ductless air conditioner
, is a cooling system that does not utilize ducts for moving treated air throughout the space. It takes warm air from one area and moving it to another. There is an outdoor compressor unit as well as air handling units indoors to allow the system to function.
The heat is transferred through the system. It goes through the cycle of evaporation and condensation. A refrigerant substance is used through a compressor pump to help achieve this cooled air. The system contains two heat exchange coils. One of those contains the necessary refrigerant material. The other works to evaporate it. This allows the refrigerant to absorb the heat from the area. This happens during the evaporation process. They work to maintain the specific temperature a person desires by using a thermostat to control the movement of the air between the coil systems.
