摘要

针对目前的家用空调系统，本文设计了一种以太阳能光伏发电技术为基础，与国家电网并网，共同驱动空调工作的系统，称为光伏并网式家用空调系统。利用光伏发电技术，通过逆变器将太阳能提供的电力转变为220 V、50 Hz家用电源，实现与市电电网的并网，来共同驱动空调运行。利用焓差实验室，对光伏并网式家用空调系统在连接100 W、135 W和185 W不同功率太阳能电池板进行空调系统的性能实验。实验结果表明：光伏并网式空调系统能稳定驱动运行。在标准工况下，与常规家用空调系统相比，制冷模式下，光伏并网式空调系统的制冷功率分别减少52 W、78 W和104 W，能效比分别提高4.2%、5.5%和10.2%。制热模式下，光伏并网式空调系统的制热功率分别减少68 W、84 W和116 W，性能系数分别提高6.4%、8%和11%。这表明光伏并网式家用空调系统是可行的，还可以有效节能。

Abstract

With the base of traditional air conditioning system

the grid-connected photovoltaic household air conditioning system based on the solar photovoltaic power generation technology is designed in this paper. The power with the solar photovoltaic power generation technology is transformed into the household power of 220 V and 50 Hz by inverter. The household air conditioning system is then driven by the transformed power and national grid. The performance of the photovoltaic grid-connected household air conditioning system was tested by Enthalpy Difference Lab under the different power (100 W

135 W and 185 W) of solar panels. The experimental results show that under normal cooling conditions

the average power consumption of the air conditioning system with the different power (100 W

135 W and 185 W) of solar panels are 52 W

78 W and 104 W lower than that of the traditional air conditioning system respectively. Similarly

energy efficiency ratios of the air conditioning system with the different power (100 W

135 W and 185 W) of solar panels are 4.2%

5.5% and 10.2% lower than that of the traditional air conditioning system respectively. Under heating mode

the average power consumption of the air conditioning system with the different power (100 W

135 W and 185 W) of solar panels are 68 W

84 W and 116 W lower than that of the traditional air conditioning system

and the coefficients of performances are 6.4%

8% and 11% lower than that of the traditional air conditioning system. It can be concluded that the photovoltaic grid-connected household air conditioning system is feasible.
