Effect of Compressor-Discharge-Cooler Heat-Exchanger Length Using Condensate Water on the Performance of a Split-Type Air Conditioner Using R32 as Working Fluid

The utilization of condensate water as a compressor-discharge cooler results in subcooling on the condenser outlet. On other hand, split-type air conditioner (A/C) with R32 working fluid can provide higher temperatures than refrigerants used same A/C. Therefore, A/C R32, equipped heat exchanger by utilizing waste-condensate cooler, has promising potential to produce largest effect air-conditioning systems. aim this study is investigate performance an using different sizes exchanger. experimental was carried out compressor capacity 1.1 kW, three heat-exchanger lengths, i.e., 18, 20 and 22 cm. indicated that longer exchangers produced degrees subcooling; lengths cm average 0.9, 1.5 4.5 K, respectively. increments degree generate improvements cooling capacity, lowering compressor-input power, enhance COP improvement were 9.1, 14.4 27.3%,
