Heat Pump in Air Conditioning Mode. When properly installed and functioning, a heat pump can help maintain cool, comfortable temperatures while reducing humidity levels inside your home Signs your Heat Pump Is In the Defrost Cycle or Experiencing Issues. The defrost cycle of a heat pump is a valuable process. It is not unusual on a frigid evening or morning for your system to go into the defrost cycle several times. You should start to recognize the defrost cycle's characteristics What is a defrost cycle? In heating mode a heat pump extracts heat from the outside air and transfers it inside your premises to warm it. When the ambient temperature outside gets very cold (close to 0°C or below) the moisture in the air freezes on the outdoor unit's heat exchanger as the fan blows the air across it. A defrost cycle is. In order to service and troubleshoot an air-source heat pump system, a service technician must understand the unit's sequence of operation. This is the order of events the system undergoes to cycle itself on and off. Knowing how the unit operates properly aids in determining where to start troubleshooting when the system doesn't operate properly Vapour compression heat pumps use a 'refrigerant' to transfer heat and his hence similar to an air conditioning unit. This diagram also illustrates how easy it is to utilise the key components but to reverse the process i.e. to pump heat out rather than in, thus becoming an 'air conditioning' unit (more correctly called a cooling unit)
