寒冷地区土壤源热泵+太阳能空调系统冬季运行特性分析

Operating Characteristic Analysis of Soil Source Heat Pump+Solar Energy Air-conditioning System in Winter in the Cold Regions

分析某建筑物土壤源热泵+太阳能综合空调系统运行特性。结果表明,太阳能热水系统在冬季大部分时间能够满足日常的生活热水需求,保证水箱温度在要求的使用范围之内。在连阴天气时,则需要热泵对其进行辅助制热以保证供水温度。该系统替代传统锅炉供热,地源热泵机组在COP为4.0的情况下运行时,一个采暖期可节省能源30%左右,减少了大量的二氧化碳、二氧化硫等污染物的排放量。因此在寒冷地区土壤源热泵+太阳能综合空调系统替代传统方式在节能与环保等方面有着巨大的意义。

This paper analyses the working characteristics of a building＇s soil source heat pump ＋ so- lar energy air-conditioning system. The result shows that in most time of winter the solar water heating system can satisfy the daily life hot water demand, and ensure the water tank temperature within the scope of application. In the cloudy days, the auxiliary heating of heat pump is needed to ensure the water supply temperature. The system can replace the traditional boiler heating. When COP is 4.0, the ground source heat pump units run, about 30~ of energy can be saved in a heating period, and the amount of carbon dioxide, sulfur dioxide and other pollutant emissions can be reduced. So it is significant that in the cold regions the soil source heat pump ＋ solar integrated air-conditioning system replaces the traditional way in energy saving and environmental protection.
