In the winter, a heat pump operates using a heat transfer process to extract heat from the outside air and transfer it inside your home. Here's how it works:
1. **Heat capture**: The heat pump extracts heat from the outside air even in cold weather. Even when the outside temperature is low, there is still heat present in the air.
2. **Refrigerant Compression**: Once the heat is captured, the refrigerant inside the heat pump is compressed by the compressor. This compression increases the temperature of the fluid.
3. **Heat Transfer**: High-temperature compressed refrigerant circulates through a coil inside your home, where it releases its heat into the indoor air. This warm air is then blown through the ventilation ducts to heat your home.
4. **Air Circulation**: During this process, a fan circulates the air inside your home, redistributing heat throughout the rooms.
In summary, a heat pump in heating mode uses a heat transfer process to extract heat from the outside air and transfer it inside your home, providing you with efficient heating even in cold weather.
