热泵型房间空调器在中国的热冷比研究 第1部分:典型城市住宅建筑的需求热冷比

Study on HCR of Heat Pump Type Room Air-conditioner in China Part I.Demand HCR of Residential Building in Major Cities

明确热泵空调器的热冷比概念,阐明空调器热冷比HCRs与空调房间需求热冷比HCRD的关系,提出HCRD的计算方法;采用模拟分析方法研究位于哈尔滨、北京、上海、深圳四城市的一套典型住宅在不同围护结构、在不同朝向、不同空调使用时段条件下的全年负荷特性,并根据热泵空调器的变工况性能特点,给出了各地节能建筑与普通建筑的HCRD范围及分布。

In this study, the definition of heating/cooling capacity ratio （HCR） of heat pump type air-conditioner was presented, and the relationship between supply HCR （HCRs） and demand HCR （HCRD） was described. The hourly loads simulated ware analyzed for a typical residential building in Haerbin, Beijing, Shanghai and Shenzhen faced to different directions and with different air- conditioner running schedules. HCRD range and distribution of ordinary buildings and energy saving buildings at different places were obtained according to the performance characteristics of the stan- dard heat pump type air- conditioner under different conditions.
