广州地区采用珠江水作为热泵热源相对于空气源热泵的优势分析
Advantages of using the Pearl River water as heat source for heat pump compared with air-source heat pump in Guangzhou
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。
Abstract：
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 airsource 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.
