  • Trial Manufacture and Performance Examination of an Adsorption Refrigerator

抄録

<p>In recent years, awareness of SDGs and environmental problems has increased throughout the world, and reducing greenhouse gas emissions and improving the penetration of renewable energy have been important to aim for a sustainable society. Therefore, in this study, the authors built a heat exchange cycle system of an adsorption refrigerator for generating cooling air by using low-temperature waste heat that can be used in summer for air-conditioning. An activated carbon and an ethyl alcohol are selected as adsorption material and refrigerant, and the target of cooling capacity is 1kW. The changes of the pressure in the testing machine and the circulating water temperatures were examined to make the characteristics clear, and the dependence of performance on the cycle time was evaluated. So that, the cooling capacity of 173.1W and the COP of 0.86 were obtained at the cycle time of 300 seconds.</p>
