Abstract
A solar electric-vapor compression refrigeration (SE-VCR) system has been proposed in this study. The SE-VCR system was investigated for different evaporating temperatures and months in Isfahan city. The system is simulated by software TRNSYS. the hourly cooling load capacities (heat gain) of a sample building during the different days were determined by using meteorological data such as hourly average solar radiations and atmospheric temperatures. The hourly total heat gain of the sample building and the hourly variations of various parameters such as coefficient of the performance, condenser capacity and compressor power consumption were calculated. the minimum photovoltaic panel surface area was determined to meet the compressor power demand according to the hourly average solar radiation data. also the economic calculations were performed for various sizes of solar system and It was found that adding solar system, is economically. also the annual consumption of carbon in the amount of 1241 kg for cooling saves.
