摘　　要： 以2007年的珠江水水温数据及当地室外空气干球温度数据为依据,对使用珠江水和空气作为热源的热泵进行了比较分析。结果表明,1-4月和10-12月期间气温较低,水源热泵蒸发温度比空气源热泵蒸发温度高5℃以上的时间占92.78%,水源热泵蒸发温度比空气源热泵蒸发温度高10℃以上的时间占60.37%,且珠江水温度比空气温度波动小,使用珠江水源热泵不会出现结霜现象,因此使用珠江水源作为热源的热泵要比空气源热泵有明显的优势。 Based on water temperature in Guangzhou reaches of the Pearl River and Guangzhou outdoor dry bulb temperature during 2007,analyses the difference of evaporation temperature between water-source heat pump using the Pearl River water and air-source heat pump.The results show that during January to April and October to December,as the outdoor air temperature is lower,the evaporation temperature of water-source heat pump is 5 ℃ higher than that of air-source heat pump for 92.78% of the time,and 10 ℃ higher than that of air-source heat pump for 60.37% of the time.Compared with air temperature,the Pearl River water temperature is more stable and smaller fluctuation.In addition,the Pearl River water-source heat pump will not frost.The performance of water-source heat pump using the Pearl River water is much better than that of air-source heat pump.
