摘　　要：为解决冬季日光温室内白天高温、夜间低温高湿的问题,将一套主动蓄放热空气源热泵系统应用于日光温室中,并对该系统开展连续运行试验。首先,从调温、调湿角度分析其环境调控效果;然后,通过性能系数COP评价不同阶段的系统性能;最后,结合蓄能水箱放热率、系统运行模式和能量利用率综合评价蓄能模块性能,为系统及蓄能模块提出优化建议。试验结果表明:系统对试验温室白天降温、夜间增温降湿效果显著。系统总性能系数为3.0~4.7;蓄能水箱能量利用率在90%以上,其工作可明显提高系统的性能系数;系统平均运行费用为0.096元/(m^(2)·d)。为日光温室的环境调控及主动蓄放热系统的优化提供新思路。In order to solve the problem of high temperature in the day and low temperature and high humidity at night in the solar greenhouse,an active heat storage and discharge air source heat pump system was applied to the solar greenhouse,and the continuous operation test of the system was carried out.Firstly,the effects of environmental regulation were analyzed from the angle of temperature and humidity regulation.Then the system performance of different stages was evaluated by the performance coefficient.Finally,combined with the heat release rate of the energy storage tank,the system operation mode and the energy utilization rate,the performance of the energy storage module was evaluated comprehensively,and the optimization suggestions for the system and the energy storage module were put forward.The test results show that the system has significant effect on cooling the greenhouse during the day and increasing the temperature and decreasing the humidity at night.The total performance coefficient ranges from 3.0 to 4.7.The energy utilization rate of the storage tank is more than 90%,and its work can obviously improve the performance coefficient of the system.The average operating cost of the system is 0.096 yuan/(m2⋅d).This study provides a new idea for the environmental control of solar greenhouse and the optimization of active heat storage and release system.
