What Is a Split System Air Source Heat Pump?
When choosing an air source heat pump, sound emissions and space requirements are crucial factors. Split heat pumps address both concerns effectively by design. What Is a Split System Air Source Heat Pump? A split system air source heat pump consists of two units: an outdoor unit and an indoor unit. The outdoor unit is positioned outside to capture energy from the air, while the indoor unit utilizes this energy to heat water for the building. The two units are connected by two pipes that carry refrigerant—one for liquid and one for gas. The outdoor unit includes a fan and an evaporator. The fan blows outside air over the evaporator, where the liquid refrigerant absorbs heat and turns into gas. This gaseous refrigerant is then compressed by the compressor, increasing its pressure before being transported through a pipe to the indoor unit. Inside the indoor unit, the refrigerant gas passes through the condenser, where it is cooled and condensed back into a liquid, releasing ene
