Abstract

This paper investigates Maximum coefficient of performance and partial load corresponding to it’ s and also optimizing energy for each Part load and each size of chiller with any Cooling capacity. The condensation temperature and outside temperature are considered as input data. The purpose of this paper is to achieve Maximum coefficient of performance with changing the number of condenser fans that depends on the condensation temperature and outside temperature and finding a relationship between Cooling capacity chiller, outside temperature and the chiller partial load in different sizes. The range of the Maximum coefficient of performance is 0. 7 to 0. 8. In other partial load range, Maximum coefficient of performance will be less though energy consumption is also higher. Also with increasing ambient temperaturefrom 30° C to 50° C, COP coefficient is reduced about 2 units.
