Abstract In this study, an artificial neural network (ANN) application which predicts of factor refrigerating capacity in a mechanical compression refrigeration system was developed. Mechanical compression refrigeration cycle, the most common cooling cycle. Element that provides heat by the evaporation of the refrigerant evaporator at low pressure environment. The Network, which has three layers as input, output, and hidden layer, has four input and one output cells. Six cells were used in hidden layers. Which back propagation algorithm was used for training. Desired error value was achieved in ANN and, ANN was tested with both data used for training ANN and data not used. Resultant low relative error value of the test indicates the usability of ANNs in this area. Capacity of change in a refrigeration system can be studied by different proceeding. Changing condenser temperature also changes the capacity of the refrigeration system. In this study, a series of experiments were performed in order to determine the effects of changing cooling water flow rate (changing condenser temperature) in a mechanical heat pump experimental setup on the refrigerating capacity of the system. Performance values obtained were used for training Artificial neural network (ANN) whose structure was designed for this operation. 1. Introduction Mechanical compression refrigeration cycle, the most common cooling cycle. Element that provides heat by the evaporation of the refrigerant evaporator at low pressure environment. High pressure steam from the evaporator to condenser compressor element is pressed. Taking the temperature of the hot gas from the compressor angry he intensification of the element condenser (condenser). Collected into a liquid refrigerant from the liquid element is stored. (receiver) Liquid various methods by restricting the passage of liquid refrigerant from the evaporator tank low pressure build up so the elements that make vaporize the refrigerant expansion valve. Performance values of a refrigerating cycle, besides a number of other factors, depend theoretically on the temperatures of the cold and warm heat sources between which the system works. Refrigerating capacity of heat pump changes depending on various parameters including temperatures of evaporator and condenser, ambient temperature, temperature of the medium to be cooled or heated, etc. Most of these parameters are not constant and can be changed on preference. Major elements of Cooling Cycle Plan as follows: 1. Condenser 2. Expansion Valve
