Abstract
This paper presents practical study to improve the indication COP of a vapor compression refrigeration cycle in instrumented automobile air conditioner by designing internal heat exchanger and installing it in the vapor compression refrigeration cycle. Two cases of vapor compression refrigeration cycle were taken in this paper: the first case is that the vapor compression refrigeration cycle without internal heat exchanger and in the second case the vapor compression refrigeration cycle with heat exchanger ; in these two cases, the temperature at each point of a vapor compression refrigeration cycle, the low and the high pressure ,the indoor temperature and the outdoor temperature were measured at each time at compressor speed 1450 rpm and 2900 rpm for each blower speed 1, blower speed 2 and blower speed 3. The refrigerant fluid was used in the vapor compression refrigeration cycle without IHE and with IHE is R134a.
