The generating system of the Absorption Refrigeration Trainer with Solar Cell Panel Unit (RBA-ART-S) is one type of cooling systems. Working principle that exist in absorption system one of them using heater, while in vapor compression system, heat is discharged by condenser to environment. If the refrigerant in the absorption system gets additional heat from the condenser in the vapor compression system it will accelerate the heating of the refrigerant present in the absorption system. From the above statement, the authors do research on absorption machine with variation of heat source by using the heat from LPG gas and also with the addition of heat calorific source from the condenser of the vapor compression system, so that the heat from the condenser can be utilized. The parameters taken in this performance test are temperature. Based on the test results obtained niali COP in the absorption system by using LPG gas of 5.781 while the value of COP for the utilization of heat of condenser with LPG gas is 5.941. Thus the process of utilizing condenser heat and LPG gas (combinations) has a higher COP value, in other words there is an increase in performance with the utilization of exhaust heat from the condenser.Â Keywords: COP, Refrigeration, and Absorption

The planning of the air system is intended to calculate the cooling load in the Hall of SMKN 1 Sekayu. So that before the AC was installed in the SMKN 1 Sekayu had an overview of the amount of AC capacity needed to condition the air in the hall with dimensions of 18 m x 16 m x 6 m. To obtain these results, the authors used the CLTD (Cooling Load Temperature Difference) calculation method based on ASHRAE GRP 158 Cooling Load Calculation Manual. Which consists of calculation of Extenal and Internal cooling loads. Calculation of cooling load based on primary and secondary data which then results are adjusted to the type of air system. After calculating the cooling load, the maximum load results are obtained at 237013,1917 Btu / hr, thus the AC capacity needed is 26 Pk with the Direct Refrigerant System, AC Floor Standing system.
