太阳能辅助加热的土壤源热泵应用研究

冬季土壤温度较低，而且以热负荷为主的北方地区，若完全采用土壤源热泵供暖，则地埋换热器和机组的初投资均比较高，连续运行的效率也较低，因此，可利用太阳能集热器作为辅助能源。以宝佳制衣厂太阳能辅助土壤源热泵系统供冷、供热、全年提供生活热水为例，从初投资、运行费用、环境效益三方面与传统空调系统进行比较，该系统比完全土壤源热泵系统更经济。

Application Research of the Geothermal Heat Pump by Using the Solar Energy as an Assisted Source

In the northern, the temperature of soil is very low and the heating load is dominant. If the peak load of heating was supplied by ground exchanger, the ground-coulped heat pump heating efficiency is low, Therefore the solar energy can be utilized as assisted source. This article makes a comparison of it with the conventional system on the total initial investment ,operation cost and Eco-efficiency combined with the construction examples of the air conditioning and refrigerating heating water geothermal pumps by using the solar energy as an assisted source system in BOGART factory. The resoults show that the program is more economical.
