Abstract

The use of a cooling machine aims to condition and refresh the room air (air conditioning). There are other types of air conditioners that use electricity and refrigerant. The heat from the ambient air and infiltration in the air conditioner is referred to as the cooling load. The purpose of testing the air conditioner is to determine the cooling capacity of the air conditioner, determine the amount of cooling load, and determine the factors that influence the COP value. In analyzing an air conditioner, a design process stage is needed which includes determining the time and place, preparing the materials, designing the air conditioner, and calculating the cooling load. This value states that the refrigerator can cool the room. The COP value is affected by the amount of air conditioning load which depends on the environment temperature, air humidity, and radiation intensity. The greater the value of room temperature and radiation intensity and the lower the humidity, the greater the COP value.
