Performance enhancement study of automotive air conditioning system using condensated water from cooling coil

Abstract

Currently, transport has played an important role in everyday life, resulting in huge traffic jams caused by big city streets and pollution problems, from global warming to global temperatures are rising. Since humans are creatures that prefer comfort in all areas, which contrasts with the higher temperatures of the Earth. Currently the use of air conditioning a lot. To modify the temperature is reduced in the range 2 3 to 25 degrees Celsius, makes people feel comfortable. However, the use of air conditioning in the car cabin cooling efficiency can be increased to a higher level than it is by cooling the refrigerant. The aim of this research is to test and compare the performance of car air conditioning systems, usually equipped with a heat exchanger. Using water from the condensation of evaporator as a medium for heat transfer. By installing the equipment at the outlet of the condenser. This causes the temperature of the refrigerant is low. The pipe lengths in the equipment from the calculation of 1 .2 meters and copper lines that increases the length of the tubes was calculated to compare with a length of 1.6 meters to test the speed of the compressor 1000, 1500, 2000 and. 2500 rpm and a wind speed of 20, 35 and 50 kilometers per hour. The results of experiment found that the temperature refrigerant equipment decreased from an average of 1.6 degrees Celsius, the pipe length of 1.2 meters and 1.6 meters of pipe temperature drops 1.8 degrees average temperature attended Eva sufficiently reduced operator. It increases energy efficiency ratio averaged 6.68% of the pipe length 1.2 m, and 22.24% at a length of 1.6 meters as well as to increase the coefficient of performance of the air conditioning system. 6 .6 9 % of the pipe length of 1.2 meters and a length of 1.6 meters at 22.4% , with the key factor in optimizing the car's air conditioning system. Making the refrigerant from the condenser, the temperature drops to pull heat out of the cabin through evaporator higher.
