Abstract

The working principle of the cooling machine is to transfer heat from a place / material with a low temperature to another place / material with a higher temperature. Refrigeration technology is very closely related to modern life, and also the convenience of life. Currently, refrigeration machine innovation is very rapid development, one of which is a basic refrigerator simulation machine. For testing carried out for 1.5 hours with data collection for 5 minutes using variations in lamp loads, so that the data obtained from the test process in the basic refrigerator simulation with two evaporators include: Temperature, pressure, electric current, voltage, Cos φ and the length of the test process, the COP (Coefficient of Performance) and input power needed can be calculated. The resulting temperature in box 1 (freezer) is -5.5°C in the 14th minute and in box 2 (chiller) is 8°C. The relationship between the cooling load and the COP of the system forms a parabolic curve, where the largest COP position is found at a load between 50 watts to 75 watts, and then the COP of the system decreases. The decrease in temperature of evaporator box 2 (chiller) is longer than the temperature of box 1 (freezer), this is because on the exit side of evaporator box 2 (chiller) installed EPR valve (evaporator pressure regulator) where this valve functions to hold the temperature of the evaporator.
