Design & Fabrication of Compressorless Solar Powered Refrigerator - Asif Ahmad - Bog

With the advent of the household refrigeration system in 1910, the modification to the core technology has been very less. The system has a compression machine designed for continuous automatic operation and for the conservation of the charges of refrigerant and oil and is usually motor driven and air-cooled. The compressor used is a power consuming component. It consumes around 90% of the total rated consumption in a refrigerator. This project emphasizes the working of a refrigeration system which does not have a compressor. The refrigerator has no rotary power consuming component, so the system has greater life longevity. The working is based on Peltier cooling comprising of a Peltier module. This is an energy efficient system consuming minimum power. Further, it also acts as a heater unit providing a localized heating. It is an air-cooled system having no flow of refrigerant. This further reduces the environmental concerns surrounding the use of a refrigerant, which has been part of great debate nowadays.
