Abstract: Governments all over the world focus on ensuring health care to every citizen. Preserving life saving medicines and making it available even at remote places is a commitment under health care. Preserving the vaccines and keeping them refrigerated all the time is a challenge as the power supply is unavailable or erratic in remote place even today. Solar energy makes a greater impact under these circumstances and can be harnessed to run the vaccine refrigerators. There are number of demonstrations supported by World Health organization (WHO) in the recent past in many countries. The method and design of a solar vaccine refrigeration with phase change material (PCM) which gives a thermal storage (TS). The utilization of PCM as TS will improve the COP (coefficient of performance) of new refrigeration cycle by presenting another sub cooling routine. This improvement sub cooling should be possible by D.C COMPRESSOR instead of A.C Compressor even a double evaporator system for refrigerator/cooler mix. Due to delaying of the compressor off time by utilizing latent heat of the we can have better vaccine storage quality because of lower hysteresis cycle of on/off for a given time of activity. To make a system level demonstrating of the refrigerator and additionally reenacted the energy utilization the new refrigeration cycle with sub cooling using PCM
