The main things is that the Refrigeration and air conditioning systems have enough capacity to maintain the desired temperature at a worst-case and also required suitable design so it can operate various load condition. For the production of hot water and space heating currently heat pump heating method is using because it is the most energy efficient method. Main advantages of heat pumps is it consume less energy, improving the performance of heating and reducing the negative effects on the environment compared to other heating methods. The further improvement of performance of vapour compression refrigeration cycles acting as heat pumps has been targeted by several researchers so that heat pumps will be able to achieve wider penetration into the building heating market. The major objective of this paper is to provide a comprehensive understanding of both simple and complex refrigeration cycles and to review the current status achieved in the performance of improved vapour compression refrigeration cycle.
