The engine performance test results in accordance with the standard ARI 2R, namely: vapor recovery rate = 0.085 kg/min, the final recovery vacuum 8,5 Psi (for 10 minutes), residual trapped refrigerant 4 grams (<1%), refrigerant loss 5 grams (≈1%). 2R machine testing conducted on air conditioner ¾ HP engine with a mass of 430 grams of refrigerant.
From the calculation and tools selection, it is resulted with 2R machine with specifications weight 20 kg, length 40 cm, width 30 cm, height 30 cm, hermetic compressor 0.25 HP (186.5 Watts) 1 piece, condenser 2050 btu/h 1 piece, copper pipe ¼ In, filter dryer 2 pieces and pressure gauge 1 piece. 2R machine is expected to help and support the refrigeration service technicians in the repair. A maximum weight of 20 kg and a volume of 0,036 m 3 is expected as the targeted result. 2R machine is designed for refrigerant R22 and the expected weight and size is much smaller than the existing 3R machine.
The current recovery, recycle and recharging (3R) machine which is a grant from Indonesian Ministry of Environment is only for R12 and R134 refrigerant which has a weight of approximately 50 kg and a volume of 0.1 m 3. 2R machine testing conducted on the airconditioner cooling engine and the type of refrigerant used is R22. The purpose of this research is to develope through some tests on a machine prototype for refrigerant R22.
This value is quite high and might gives great effect on the destruction of the environment, therefore developing a machine that serves as a recovery and recycle (2R) refrigerant is a necessary solution. R22 is a refrigerant that has a value of Ozone Depletion Potential (ODP) of 0.06 and Global Warming Potential (GWP) of 1700. One of it is HCFC or R22 which is widely used as a cooling medium. Synthetic substances which have high impact to the destruction of the ozone layer are the refrigerant used for cooling system. ABSTRACT DEVELOPING OF A PROTOTYPE PORTABLE MACHINE RECOVERY AND RECYCLE FOR REFRIGERANT R22 MAHENDRA NIM : 21050111400009 One of the most concerning environmental pollution nowadays is the destruction of the ozone layer which is caused by contaminated synthetic substances or man-made ozone depleting substances.
