摘要
将利用相变材料蓄冷的太阳能光伏直流冰箱的运行特性与不带蓄冷的光伏直流冰箱及常规冰箱进行对比实验,带有蓄冷功能的冰箱在压缩机启停次数、运转率及停机保冷时间上较后两者有较大优势,能有效延长压缩机的使用寿命。此外,系统完全由太阳能供电而不消耗电网电能,是真正意义上的"绿色家电",特别适用于偏远山区以及游牧民族地区的食品保鲜以及疫苗等医疗卫生用品的冷藏。
The compared experimental tests were carried out to investigate the operation performances of a solar photovoltaic DC refrigerator using a phase change material（PCM） , a photovoltaic DC refrigerator without PCM and a household one. The photovohaic DC refrigerator using PCM has many advantages for on-off frequency of the com- pressor, service factor and heat insulation time as compressor stopped, so to prolong the service life of the compres- sor effectively. Furthermore, the system is powered by solar energy completely without consuming any grid electrici- ty for running, and is the ＂green household electric appliance＂ on real significance, that especially suitable for remote mountains and nomadic areas of fresh food and medical supplies of vaccine, etc.
