Abstract Value addition of agro products improves the livelihood opportunities for rural farmers. Cold Storage is one of the techniques to improve the shelf life of agro product. With the increase in the utilization of refrigeration and air cooling using vapour compression refrigeration technology, global warming and ozone depletion due to the refrigerants have also been increased. So, to overcome this problem, several restrictions were placed on the refrigerant by the United Nations Framework Convention on Climate Change (UNFCCC). There is no way to slow down the growth of this technology, so the focus should be shown on finding an alternative. Various studies have been carried out on an alternate refrigeration system. This paper attempts to study the power quality challenges in the conventional vapour compression system. A comparative analysis of vapour compression refrigeration (VCR) and vapour absorption refrigeration (VAR), power factor analysis and temperature measurement on both technologies has also been carried out and reported. Keywords VAR . VCR . Power factor . Refrigerant . Global warming . Ozone depletion

Introduction Refrigeration is the removal of heat from a selected environment to the desired level and dissipating the heat to the surrounding. For the process to work, a working fluid is required, which is refrigerant. Historically, even before the invention of refrigeration technology, the concept of refrigeration was there (Gantz 2015). It was in practice by utilizing the runoff water from the fresh snow for food storage, or even the natural ice was harvested and sent for trade, which is also mostly used for food storage. Even salts like NaCl and CaCl2 were used to reduce the temperature up to − 20 °C to − 50 °C. After several decades of research, the current refrigeration technology was brought into effect. Refrigeration is requi
