PURPOSE:To improve cooling capacity of evaporator by providing a drain pipe to be inserted with high pressure refrigerant piping and cooling the refrigerant with drain flowing through a discharge pipe thereby increasing over-cooling degree of refrigerant. CONSTITUTION:Drain produced through cooling operation of evaporator 10 will flow along the bottom face of cooler case 12 then enter through a drain port 15 into a water pipe 16 and discharged through an opening 18. Since the gap between the drain path 14 or branch 8 and the water pipe 16 is small, approximately saturated cooling liquid from a receiver tank 7 is overcooled by the drain 14 having temperature of 0-10 deg.C to considerable degree when reaching to an expansion valve 9. In such a manner, cooling capacity of evaporator is increased resulting in reduction of size of evaporator or compressor. |
