[Abstract]:Simulation analysis and experimental study of photovoltaic energy transfer characteristics of ice-storage air conditioning driven by independent photovoltaic energy are carried out. The results show that the theoretical calculation value of external cooling power is 176.51 W and the measured value is 171.58 W under the typical sunny conditions in Kunming, and the model can well reflect the energy transfer characteristics of the system. Energy loss and loss of components. The energy utilization ratio of the system is 7.45. The evaporator of the photovoltaic module and the ice making system account for 86.72% of the total energy consumption and 90% of the input cooling rate of the evaporator respectively. The efficiency of the system is 38.51, and the converted electric energy value of the photovoltaic module is 547.91 Ws, accounting for 58.833 of the system value. The photovoltaic module has the largest loss, accounting for 54.57% of the total loss, the compressor of the ice making system accounts for 51.97% of the component loss, and the evaporator loss of the ice making system accounts for 26.76% of the evaporator input.
