Abstract

This research is a study of Heat Exchanger Produces Hot Water from Air Conditioning Incorporated with Solar Energy System. Its objective is to compare the efficiency of heat exchanger produces hot water from the air conditioning incorporated with the solar energy. The experiment with hot water system is separated into two sections. The first section is the split operation of air conditioning and solar energy producing hot water and the second section is solar energy producing hot water incorporated with waste heat recovery from air conditioning. The study reveals that the temperature of solar energy producing hot water is 48.7 °C. While, the maximum temperature of hot water incorporated with waste heat recovery from air conditioning is 52.0°C with 0.025 kg/s of water flow rate. This flow rate through heat exchanger is the most efficient in the experiments on hot water production. In comparison with the first section, the temperature of hot water produced by the solar energy incorporated with waste heat recovery from air conditioning is increased by 3.3 °C and can save 21.7% of energy.
