Application and thinking of air-air energy recovery equipment

Air-air energy recovery equipment is more and more widely used because of its energy efficiency and convenience. Analyses and discusses an air-air energy recovery equipment as outdoor air handling unit to cool down multiple rooms. Points out that the less the number of air-conditioned rooms, the lower the actual energy recovery rate of the equipment, and the higher the outdoor air load of the air-conditioned rooms. Suggests installing electric airtight valve in outdoor air branch ducts and exhaust branch ducts or outdoor air inlets and exhaust outlets in order to solve the problems.
