Abstract
The systems cooling hybrid solar uses solar collector to convert solar energy into the source of heat for roasting Refrigerant outside of the compressor and this process helps in the transformation of Refrigerant from the gas to a liquid state in two-thirds the top of the condenser instead of two-thirds the bottom of the condenser as in Conventional cooling systems and this in turn reduces the energy necessary to lead the process of cooling. The system cooling hybrid use with a capacity of 1 ton and Refrigerant type R22 and the value of current drawn by the system limits (3.9-4.2A), the same value of electric current calculated by the system are Conventional within this atmosphere of Iraq, and after taking different readings of the temperatures and pressure to several points in the system's found that the Refrigerant when it comes out of the compressor, it loses part of the temperature of the water in the solar collector through a heat exchanger while the literature published in accordance with the manufacturers that the solar collector, a kind of vacuum tubes contributes to raise the pressure and temperature of the fluid cooler to reduce the consumption of energy spent on compressor. Therefore, the system described by the current not fit for domestic use within the Iraqi environmental conditions.
