Enhancing Air Conditioner Efficiency Through Evaporative Cooling of the Compressor: Field Test Results

Energy demand for the air conditioning sector is increasing due to increasing population, increasing living standards, and global warming. This increase in demand must be accompanied by efforts to increase energy efficiency. Evaporative cooling is one effort that can be chosen to increase the energy efficiency of the air conditioning system. The use of evaporative cooling by utilizing condensate water from the evaporator has been experimentally investigated. This research was conducted directly on an air conditioner unit that had already been installed in a room. Specifically, experiments were carried out by flowing and dripping condensate water into the compressor body of an air conditioner and examining its effect on the performance of the air conditioner. The research results show that the use of condensate water can reduce suction temperature, discharge temperature and condensation temperature by 0.7 degrees C , 3.2 degrees C , and 1.2 degrees C , respectively. As a result, cooling capacity increases by 2.8%, energy consumption decreases by 3.5%, and energy efficiency ratio increases by 7.6%. Overall, the use of condensate water for compressor cooling can improve air conditioner performance.
