Abstract: Fundamentally, a vapour compression refrigeration system (VCRS) is a device that absorbs heat from a lower internal heat level and rejects it to the body or environment at a higher temperature in exchange for some external work being done on it. It is widely used everywhere, from commercial use in homes and stores to extensive scope and significant cooling loads in companies. They vary in size as well, but only to the extent necessary for cooling. to operate with top blowers, provide large cooling loads with minimal energy or force consumption Manyanalysts working in the subject of warm designing have always been interested in it. The area of refrigeration is similarly changing as a result of the introduction of nanotechnology in all research and technological fields. not anymore left clean of it. It has been observed that severalmetals and their combinations have high heat dissipation limits, which formed the basis for their use in refrigeration. Numerous nano size metal mixes have been tested with numerous refrigerants, and suitable fixes have been discovered to ensure an increased VCRS Coefficient of Execution. In this endeavour as well, a unique mixture is used, and research on VCRS will be conducted. Here, the task of finding the best fixations is completed afterthe mixing of metalCuO nanoparticles with the refrigerant R134a is complete.
