Abstract

Abstract:

This paper adopted air source heat pump combined with pipeline ventilation method to heat the solar greenhouse，test indoor thermal environment，calculate the COP of air source heat pump，and compared the energy saving rate with the traditional coal-fired boiler．The test results showed that the average COP value of a typical sunny air source heat pump was 1.76，saving 23.4% energy compared with coal-fired boiler．Adopting air source heat pump to heat the greenhouse，the temperature of day time could reach 23.09 ℃，and 8.68 ℃ at night，compared with that of the contrast greenhouse increasing 6.95 ℃ and 3.99 ℃，respectively．The calefacient effect was obvious．At day time，the relative humidity was 47.45%，and 70.02% at night，reducing by 18.56 and 18.75 percent Point，respectively．The dehumidification effect was also obvious．

Key words: Solar greenhouse, Air source heat pump, Winter warming, Coefficient of performance（COP）, Energy saving rate

摘要：

采用空气源热泵配合管道通风的方式对日光温室进行加温处理，测量室内热环境、计算空气源热泵的性能系数（COP）以及与传统燃煤锅炉加温进行节能比较，研究空气源热泵冬季温室的加温效果。结果表明：典型晴天空气源热泵的平均COP 值为1.76，与燃煤锅炉加温相比节能23.4%。采用空气源热泵加温，温室白天平均温度可达23.09 ℃，夜间8.68 ℃，比对照温室分别提高6.95 ℃和3.99 ℃，增温效果明显；温室白天平均相对湿度为47.45%，夜间为70.02%，比对照温室分别降低18.56、18.75 个百分点，除湿效果明显。
