太阳能热泵系统的稳定性

Stability of the PV/T-SAHP system

在相同的压缩机频率、冷凝水温和相同的电子膨胀阀开度下,文章对PV/T-SAHP系统的动态性能进行了实验和分析,就不同太阳辐照度和环境温度对PV/T-SAHP系统性能的影响进行了对比,提出了光伏-太阳能热泵(PV/T-SAHP)的系统稳定性原理,指出PV/T-SAHP系统需要解决的一些问题。

At the same frequency of the compressor,the same opening of the electronic expansion valve and the same temperature of condensing water, outdoor tests are conducted on the PV-SAHP system. The dynamic behavior of the PV-SAHP is experimented and analyzed and the influences of solar exposure and enviornment temperature on the system are also compared. Then the principle of the stability of the PV-SAHP system is put forward. Some problems to be solved in the system are pointed out.
