Air source heat pumps cool by reversing their heating cycle to remove heat from indoors and release it outdoors. In cooling mode, they function much like air conditioners.
Here's a breakdown of the cooling process:
-
Refrigerant Cycle: The heat pump uses a refrigerant that cycles between liquid and gaseous states, absorbing and releasing heat.
-
Indoor Heat Absorption:
-
When set to cool, the heat pump pumps chilled water through the heat pump convector.
-
As the fans draw warm air from the room over the heat exchanger, the cold water within cools the air.
-
-
Outdoor Heat Release: The absorbed heat is then transferred to the outside air via the outdoor unit.
-
Cooled Air Distribution: This cooled air is then dispersed back out into the room, reducing the temperature.
| Step | Description |
|---|---|
| 1. Circulation | Chilled water circulates through the heat pump convector. |
| 2. Air Intake | The fans draw warm air from inside the room over the heat exchanger. |
| 3. Cooling | The cold water inside the heat exchanger cools the warm air. |
| 4. Distribution | The cooled air is blown back into the room, reducing the overall temperature. |
