Study on Load Calculation Method for Air-Source Heat Pump Cooling and Heating System
摘要
Abstract
Using the dynamic load simulation method of DeST software,the hourly heating and cooling loads under different conditions are investigated,and the load calculation method for residential buildings applying the air-source heat pump cooling and heating system in hot summer and cold winter areas is proposed.The intermittent coefficients α and intra-house heat transfer qh for different types of rooms are analyzed.The results show that,in summer,the living room with an area of 29-45 m2 should have α set at 1.5 and qh at 55 W/m2,the bedroom with an area of 15-20 m2 should have α set at 1.4 and qh at 55 W/m2,and the bedroom with an area of 8-15 m2 should have α set at 1.0 and qh at 60 W/m2.In winter,the living room with an area of 29-45 m2 should have α set at 2.0 and qh at 40 W/m2,the bedroom with an area of 15-20 m2 should have α set at 1.6 and qh at 40 W/m2,and the bedroom with an area of 8-15 m2 should have α set at 1.5 and qh at 45 W/m2.The total system load α should be set at 0.7 in summer and 1.1 in winter,with qh set at 13 W/m2 in summer and 12 W/m2 in winter.Window-wall ratio and orientation correction values are provided,where rooms with a summer window-wall ratio greater than 0.3 should be reduced by 0.1 from the original recommended values,and north-facing rooms in winter should be reduced by 0.1 from the original recommended values.关键词
