00:00:00 - 00:05:00

A heat pump is a device that uses the same basic principle as an air conditioner to transfer heat from the hot outside air to the colder inside air. The compressor is constantly changing the pressure of the refrigerant, which updates the temperature of the system. This allows the user to precisely control the temperature of the building, regardless of the outside temperature.

• 00:00:00 The heat pump explained in this video uses the same basic principle as air conditioning systems to transfer heat from the hot outside air to the colder inside air. When the compressor is activated, the heat is dumped to outside and the cycle repeats.
• 00:05:00 In this video, a heat pump is explained, with particular focus on the reversing valve. The compressor is constantly changing the pressure of the refrigerant, which updates the temperature of the system. This allows the user to precisely control the temperature of the building, regardless of the outside temperature.
