- The evaporator extracts energy from the renewable source (air, water, geothermal or solar) by forcing the liquid to transform into a gas.
- The compressor compresses the gas, which raises its temperature.
- The condenser exchanges the heat from the gas to the heating system, and the gas returns to a liquid state.
- The expansion valve lowers the pressure of the refrigerant, which triggers evaporation and the cycle begins all over again.
We simply reverse this cycle to cool your home.
