Abstract
It is important to cool a photovoltaic (PV) panel, because increased panel temperature is accompanied by decreased power generation efficiency. The authors have proposed a PV power generation system combined with an adsorption chiller driven by low-temperature heat, and simulated temperature changes during the desorption cycle, where the chiller utilizes endothermic reactions of an adsorbent during the desorption cycle. Described herein are results of the tests carried out to validate possibility of controlling panel temperature increase. The system consists of the PV panel with which a bed packed with an adsorbent is monolithically combined, condenser and evaporator. It generates power during the daytime by sunbeams, and provides low-temperature heat during the nighttime by the evaporator. In particular, ice can be produced when methanol and activated coal are used as the adsorbate and adsorbent. It has an advantage of effective utilization of energy as the heat source, which has been merely dissipated by the conventional system in the air. Such a system is expected to be useful for promoting effective utilization of solar energy and for peak power shaving in summer. The initial targets are achieved by the tests. 4 refs., 10 figs.
