Cooling machine with refrigerant system is a machine worked with based on the refrigeration cycle of thermodynamically can transfering heat from a low temperature to a high temperature area with the help of the compressor work. Coolant machine is used to decrease the temperature of the rooms, so it can be cool rooms. The process of cooling the room, using a refrigeration cycle, with referigerant as its main ingredient. Refrigeration cycle can function optimally if the refrigerant in accordance with the amount (determined brand, the size of the air conditioner). Test equipment vapor compression cooling machine has been made previously by Maradona and M Syafe'i in 2008 with refrigerant R-22 and the expansion device with a capillary tube type of AC window, brand Sanyo power 1 HP. And then this machine modifycated with addition of expansion device types thermostatic and hot spot water heater using type refrigerant HCR-22 with a mass of refrigerant is 0.55 kg using type AC window power ¾ PK National of brand.
The making of component is frame supporter of the with capacity of the tank is 50 L, making place of fan, making place valve of refrigerant , making hot spot water heater, and asembilng of capiler pipe.
Keywords: Hybrid cooling machine, Refrigerant HCR-22
