对一种独立光伏空调冬季热泵运行特性进行实验研究。实验表明,系统在上海地区冬季白天的采暖中,太阳能可提供空调运行所需的77.7%电量,夜晚蓄电池可提供空调运行的全部电量,但到第2天尚未被充满。系统中逆变器的效率在61%~74%之间,影响系统的整体性能。此外,还对蓄电池的性能进行分析,并对系统的改进提出建议。 An independent photovoltaic air-conditioning winter heat pump operating characteristics of an experimental study. Experiments show that the system can provide 77.7% of the electricity needed for air-condition operation during the daytime heating in Shanghai during the daytime and nighttime. The battery can provide the full capacity of air-conditioning operation at night, but it has not been fully charged by the second day. The efficiency of the inverter in the system is between 61% ~ 74%, affecting the overall performance of the system. In addition, the performance of the battery is also analyzed and suggestions for system improvements are made.
