Internal loads effects on the air conditioning system are important in determining the comfort condition. This is done by evaluating the heat distribution. The internal loads' effects depended on how much the sources of heat released its energy. As the result, the heat distribution will affect the room properties such as temperatures, relative humidity and the dew point. Thus, it is related with the comfort level. This is due to the fact that the compressor would be automatically on and off as long as the air conditioning system was switched on. The more heat released by the lighting bulbs and the equipments means the more energy consumed by the compressor in order to keep the space as comfortable as wanted. Hence, to maintain the comfort level, equivalence energy consumed needed to remove the heat released by the lighting bulbs and the equipments. And it could be elaborated in the term of the electrical usage of the compressor as it responded with the condition. This could lead into the determination of the general characteristics and heat distribution and the analysis of the two sources of the internal loads (equipments and lighting). In conclusion, it is found that the internal loads had affected the air conditioning system in the term of temperature changes and the electrical usage by the random heat distribution. The internal loads in the heat released term, had affected the temperature and comfort condition and in order to maintain the condition, equivalence energy consumed were needed.
