Abstract: The environmental risks of CFCs and HCFC are well known and they warrant particular banning them: they contribute to the destruction of the stratospheric ozone layer. Their Bench, HFC, are not participating in this destruction but on the other hand help the greenhouse effect. One of the alternatives for replacing the CFC and HCFC, is to use other refrigeration systems that do not use these refrigerants pollutant environment among these refrigeration systems, the absorption refrigeration. Hence, the possibility of developing air conditioning systems coupled with a solar system that can guarantee the conditions of comfort with a saving energy. The solar coupled with refrigeration systems, must be optimized depending on the site and its applications so they can provide a conversion efficiency-cost of implantation. In our study, it proposes a program to calculate the solar fraction using the method Phibar-fchart, with the meteorological data of the Ouargla region (south-eastern Algeria). Simulation results show that the optimum angle of inclination of the solar collector is 45� so that the solar fraction peaked, believes solar fraction linearly with the capture solar surface, this result should be involved in any study technical-economic status of solar systems, in order to have an optimum design of the facility.
