Abstract

Air conditioning system is a cooling system whose function is to condition the air according to the desired needs. Air conditioning can be done in workspaces, foodstuffs, or industrial products that are desirable in accordance with the needs. The cooling system used is a steam compression system. The problems faced so far are the amount / weight of the refrigerant (cooling material) and the rotational speed of the condenser fan to the cooling capacity of the cooling system. The refrigerant that used in this research is R22 refrigerant and hydrocarbon refrigerant (Musucool / MC 22). The purpose of using these two refrigerants is to find out the performance of the air conditioning system by using R22 refrigerant and hydrocarbon refrigerant (MC 22) through variations in fan rotation speed on the condenser. The method used in this research is an experimental method with an existing refrigeration machine, which is a refrigerant machine 22 (R22). The testing is carried out in stages, namely vacuuming the system, charging refrigerant in the form of Freon R22 and also hydrocarbon refrigerant (MC 22) which is carried out on the basis of the weight / mass of the two types of refrigerant, then the air velocity varies in the condenser. Furthermore, the system working pressure measurements are measured either low pressure (LP) and high pressure (HP) of the system as well as performance measurement in the form of the Coefficient Of Performance (COP) system and current consumption that occurs. The test results show that at low rotation (200 rpm), the system pressure is higher, namely 100 psi for R22 and 95 for R290, while at high rotation (750 rpm), the system pressure is 91 psi for R22 and 90 for R290. Likewise, the consumption of electric current from 2.9 A to 2.2 A on R22 and 2.2 to 2.0 on R290.
