How does temperature transfer in hvac system
WebThe refrigerant then changes phase to a gas and is put through a compressor to increase its temperature. Refrigerant then passes through the condenser coils, transferring heat from the refrigerant to the outside air. Refrigerant expands in order to decrease its pressure and cool down to below the room's temperature to repeat the cycle again.
