STUDY ON THE PERFORMANCE OF A FRESH AIR HEAT EXCHANGER
Indoor air quality (IAQ) has become one of the topics to which much attention is paid during the 21st century. Ventilation is one of the most effective means which can improve the indoor air quality, but it also means the increases the energy consumption for air-conditioning, and has already accounted for 30％ or more of the whole building demand. An effective fresh air heat exchanger is introduced in this paper. The design characteristic and structure style of the fresh air heat exchanger is presented, and its thermodynamic performance was tested based on simulating the condition of an air-conditioning room. The results indicate that its efficiency is more than 70％, and it can meet designation criteria. The fresh air heat exchanger, which features as: small in size, light in weight, simple in structure, and low cost, can be used solely, and cooperated with other energy recovery system.
