Abstract
The static ice refrigeration air conditioning system (SIRACS) driven by household distributed photovoltaic energy system (HDPES) was proposed and the energy conversion as well as the transmission performance were investigated by combining the theoretical calculation with experimental test. Results revealed that the system could be operated stably and continuously during three typical weather conditions (sunny, cloudy and light rainy) with an average photoelectric conversion efficiency of 11.76% and an average ice production of 52.56kg. This system could continuously and stably serve user for 4h during night. The models were verified to be reasonable and the simulated results were reliable. Meanwhile, the system average energy efficiency η was 7.65%. The performance analysis results showed that the ice making efficiency of the refrigerator was 50.19%, which was mainly responsible for the low energy efficiency. Therefore, to improve the refrigeration performance some optimization strategies were recommended and proposed in this paper.
