【中文摘要】 对低环境温度空气源热泵(冷水)机组(简称低温热泵)标准中的名义制热工况确定问题进行了研究。通过对我国寒冷地区典型城市供热季节的室外干球温度及其对应湿球温度的分布进行统计分析,确定出低温热泵空气侧的名义制热工况条件为-12℃/-13.5℃;通过对典型房间分别采用风机盘管和辐射地板进行供热时,保证室内舒适性要求的空调末端出水温度的研究,给出了水侧的名义制热工况为回水温度38℃。上述结论可为商用和户用低环境温度空气源热泵(冷水)机组的标准制定提供参考。 【英文摘要】 The nominal heating condition of low environment temperature heat pump (water chilling) packages was determined. The nominal dry bulb temperature and wet bulb temperature on the air side may be -12℃ and -13.5℃,respectively,according to the statistical result of outdoor temperature from typical cities in the cold area of North China. The nominal return water temperature on the water side may be 38℃ which could meet comfort demand in a typical room heated by floor panels and fan-coil units. 【中文关键词】 热工学; 低温热泵; 名义制热工况; 标准 【英文关键词】 Pyrology; Low temperature heat pump; Nominal heating condition; Standard
