Air conditioning is a device whose function is to condition the air according to the desired needs. The problem faced so far is that the refrigerant used can have a negative impact on the environment such as the potential for global warming and ozone destruction and disturbing human health. The refrigerant used in this research is the hydrocarbon refrigerant (MC22). The goal is that hydrocarbon refrigerants have the property of being able to lighten compressor work and environmentally friendly.

... The method used in this research is an experimental method. The test is carried out in stages, namely system vacuuming, refrigerant charging carried out on the basis of the weight of the refrigerant, measurement of system working pressure and performance measurements system and current consumption. The test results show the mass efficiency of the refrigerant and the consumption of electric current respectively 500gr or 50% and 6.3A or 33%.
