Perbandingan Performansi Kompresor Elektrik dan Typical Menggunakan Refrigerant R-134a pada Sistem Air Conditioner (AC) Mobil

Abstract

The air conditioning system (AC) is an air conditioning process where the air conditioning is desired, regulated, filtered and perfected so that the quantity and quality of the adjusted air conditioning can ultimately be controlled with the aim of providing air comfort for the driver and passengers, as well as regulating flow, pressure , and air quality. The aim of this research is to analyze the performance comparison results for electric and typical compressors in car AC systems that have been designed by determining, compressor work, refrigerant mass flow rate, heat released by the condenser, heat absorbed by the evaporator, and coefficient of performance ( COP). Then analyze the comparison results of fuel consumption when the AC is turned on using an electric and Typical compressor. The results of this research show that the refrigerant mass flow rate increases with increasing compressor rotation, this is because the ratio of the refrigeration capacity which has been set at 2.015 kJ/s with the heat absorbed by the evaporator (the difference between the heat at the compressor input and the heat input from the evaporator) is getting smaller. Compression work increases with increasing compressor rotation, this is because the mass flow rate of refrigerant increases from the difference between the compressor output heat and the evaporator output heat which increases, so compression work increases, the heat released by the condenser increases with increasing compressor rotation, and COP decreases with increasing compressor rotation. Comparison of the fuel consumption of electric and typical compressors at 800 rpm and 1000 rpm has been obtained where electric compressors are 39% more efficient than typical compressors.
