An air to water heat pump extracts heat from the outside air and transfers it to a water-based heating system, providing both space heating and hot water for a building. It works by using a refrigerant cycle to absorb heat from the air, compress it to a higher temperature, and then transfer that heat to water, which is circulated through radiators or underfloor heating systems.
Here's a more detailed breakdown:
- 1. Heat Absorption:
The heat pump's outdoor unit contains an evaporator that absorbs heat from the outside air, even at low temperatures, using a refrigerant.
- 2. Compression:
The refrigerant, now in a gaseous state, is pumped to a compressor. The compressor increases the refrigerant's pressure and temperature.
- 3. Heat Transfer:
The high-temperature, high-pressure refrigerant passes through a heat exchanger where it transfers its heat to the water in the central heating system.
- 4. Refrigerant Cycle:
The refrigerant, having lost its heat, returns to a lower temperature and pressure, and the cycle repeats.
- 5. Heating Distribution:
The heated water is then circulated through radiators, underfloor heating, or a hot water cylinder to provide heat to the building and its occupants.
In essence, an air-to-water heat pump acts like a refrigerator in reverse, moving heat from one place to another rather than removing it. It's a renewable energy-powered system, with the heat pump using electricity to drive the process, but relying on ambient air for a significant portion of the heating energy.
