Benefits of Heat Recovery Exchanger when used in conjunction with air conditioning:

Summer: When the HRVU is used in the summer, the energy of the cold air discharged from the room is used to pre-cool the hot, ambient outside air before it enters the room.

Winter: When the HRVU is used in the winter, the energy of the warm air discharged from the room is used to pre-heat the cold, ambient outside air before it enters the room.
