Energy-saving Performance Test and Application Research of the Fresh Air Heat Recovery System for Residential Building in Hot Summer and Cold Winter Zone
The actual energy-saving effect of the system in each season was judged in order to analyze the energy-saving performance of outdoor air heat recovery system for residential buildings in hot summer and cold winter area.The heat exchange efficiency,heat recovery and indoor fresh air load of fresh air heat recovery system are calculated by field test,the electricity energy consumption and relative energy saving rate of a residential building before and after using the fresh air heat recovery system are calculated and analyzed.The results show that the relative energy-saving rate of the building increases from 2.60%to 6.09%,the energy-saving rate of heating in winter is 3948.35 kW·h,the energy-saving rate of air-conditioning in summer is 2036.22 kW·h,the total power consumption is reduced by 5984.57 kW·h,and energy saving is realized by 3.57%.The above research contents can provide reference for the design,application and research of the outdoor air heat recovery system.
