Abstract

A numerical analysis was presented in this study to investigate the thermal effectiveness of a hybrid air-conditioning system that uses solar power. The climate of Iraq, and specifically the city of Nasiriyah, was adapted to solar radiation. The hybrid evacuated tube solar air heater was used in this investigation. The system was created and produced to withstand Iraq's scorching heat. Ten evacuated tubes were assembled in a solar system that measured 1.8 square meters. This system was tested from 8:00 AM to 7:00 PM in June under the effects of sun radiation. The effectiveness of solar collectors in terms of energy conservation and system efficiency was discussed. The experiment described in this study was carried out twice. First: In the first scenario, the solar heater was connected before the compressor. According to the results, average heater temperatures increased from 25% to 55% of the total energy used for the cooling cycle each day, resulting in increased energy savings. The gas was heated to temperatures between 45 and 65 °C, with a continuous cooling rate of 3.43. Second: In the second instance, the solar heater was connected following the compressor. With an average system performance factor of 5.1 to 13 and energy consumption ranging from 15% to 24%, the solar heater significantly increased system efficiency. Take note of the increase in cooling load from 3.43 to 5.54 kW. In the second instance, the rate of thermal heating increased steadily from 100 to 160 ° C. The system has improved as a result of increasing the cooling load while reducing energy consumption and raising the overall performance of the system factor as a result of the improvement of the special conditions of the coolant used in the (R-410a) cycle, it should be noted that the second case has a much greater service advantage and economic viability than the first.
