This paper presents a novel hybrid solar cooling system driven by a concentrated photovoltaic/thermal unit (CPV/T). The electricity of the PV module is used to power the thermoelectric cooler while the thermal energy is used to run an absorption cooler. The effective cooling of the PV module provides more electricity, but less thermal energy quality (temperature). Thus, there is more cooling effect from the thermoelectric cooler and less cooling effect from the absorption cooler. The major aim of this study is to optimize the performance of the PV panel cooling in order to find the maximum total cooling effect. A mathematical model of the proposed system has been presented. The model is validated and used to investigate the performance of the system under a wide range of operating and design conditions. The results showed that less cooling of PV panel provides the maximum total cooling capacity, so in order to conduct the optimization process, the COP of the thermoelectric cooler should exceed 6.4 which implies the figure of merit to be 70. The overall COP of the system at 1000 W/m² increases from 0.151 to 0.233 when the PV/T outlet temperature increases from 65 to 90 °C.

本文介绍了一种新型的混合太阳能冷却系统，该系统由集中式光伏/热力装置（CPV / T）驱动。PV模块的电力用于为热电冷却器供电，而热能用于运行吸收式冷却器。PV模块的有效冷却可提供更多电力，但热能质量（温度）却较低。因此，来自热电冷却器的冷却效果更大，而来自吸收式冷却器的冷却效果更少。这项研究的主要目的是优化光伏面板的冷却性能，以找到最大的总冷却效果。提出了系统的数学模型。该模型经过验证，可用于调查各种操作和设计条件下系统的性能。当PV / T出口温度从65°C升至90°C时，²从0.151升高至0.233。
