摘要
为了探究利用热源塔热泵系统对陕南地区以及气候相近地区进行冬季供暖的可行性,设计了一套小型闭式热源塔热泵系统,并在冬季条件下,对该系统的制热性能进行了实验研究。分析结果表明:当环境温度为5.1~5.4℃,环境相对湿度为92.1%~94.5%时,闭式热源塔热泵系统的供热温度高于46.7℃,制热功率大于13 kW,热泵机组COP的平均值为2.86;当环境温度为2.5~0.1℃,环境相对湿度为80.4%~89.5%时,闭式热源塔热泵的供热温度高于43℃,制热功率随着环境温度的降低而减小;当环境温度达到最低值(0.1℃)时,制热功率为11.4 kW,热泵机组COP的最低值为2.64,这表明热源塔热泵系统可以应用于陕南地区以及其他气候相近地区。
In order to explore the technical feasibility of using heating tower heat pump technology for building heating in southern area of Shaanxi in winter,a closed-type heat tower heat pump system was developed.An experimental study under winter weather conditions was conducted to reveal its heating performance.The results showed that,when the ambient temperature is in the range of 5.1~5.4℃,and the relative humidity is in 92.1%~94.5%,the heating temperature is higher than 46.7℃,the heating capacity of the system is exceeds 13 kW,and the average COP of the heat pump unit is 2.86;when the temperature changes from 0.1~2.5℃,and relative humidity between 80.4%~89.5%,the heating temperature is higher than 43℃,the heating capacity of the system decreases to 11.4 kW as the ambient temperature decreases to lowest with 0.1℃,and the heat pump unit has the lowest COP is 2.64.The results indicated that the heating tower heat pump system can be used as a heating source for buildings in southern Shaanxi and similar climate areas.
