摘要
主要以土壤热源热泵为研究对象 ,从技术和经济性两方面对其与风冷热泵进行了分析和比较。分析的结果表明 ,土壤热源热泵的性能参数 (COP)比风冷热泵有较大提高 ,初投资和运行费用要比风冷热泵节约。同时还分析了土壤热源热泵在采用太阳能为辅助热源后 。
Taking the soil heat pump as the study project, compared with the air cooling heat pump, the soil heat pump is analyzed technically and economically. Technically speaking, Coefficient of Performance (COP) of soil heat pump is superior to air-cooling heat pump. Although the initial investment of the soil heat pump is higher than air cooling heat pump, the operation cost could been saved. Its net payoff in its life span is much higher than air cooling heat pump. At the same time, the operation cost of soil heat pump could be greatly reduced when the solar energy is taken as the assistant heat source.
