초록

Experimental results are presented for heat transfer and pressure gradients of HCs refrigerants R-290, R-600a, R-1270 and HCFC refrigerant R-22 during evaporating inside horizontal double pipe heat exchangers. Two tubes with a tube diameter of 12.70mm and 9.52mm are used for this investigation. Hydrocarbon refrigerants have higher pressure drop than R-22 in 12.7mm and 9.52mm. The results from the investigation can be used in the design of heat transfer exchangers using hydrocarbons as the refrigerant for the air-conditioning systems.
