Abstract:
Currently, refrigeration machines have a very important role in domestic, commercial, industrial, and transportation needs. One type of refrigeration machine is a freezer machine that is used for mobile ice cream sellers. A prototype freezer machine for mobile ice cream sellers has been made. The DC compressors and solar PVs will be used on these mobile ice cream sellers. Solar energy is the largest renewable energy on earth that can be converted into electrical energy. The electrical energy produced by solar PVs will be stored first with batteries before use in the DC freezer system. The components of the solar PV system include solar PVs, solar charge controllers, and batteries. The DC compressor used is a hermetic type with a power of 100W, while the condenser is equipped with a fan motor with a power of 12W. By considering the operation of the DC freezer machine for 8 hours a day, the solar PVs used to have a capacity of 300WP, monocrystalline type. While the size of the solar ch
arge controller is 20A and the battery used is 12V and 200Ah. From the test, the COP value is 4.97 and the energy consumption is 13.61kJ.
