Abstract
In this study the absorption refrigeration cycle without an electric solution pump is proposed. To accomplish this cycle, porous material is introduced in a generator, which is able to keep the pressure difference between high-pressure refrigerant vapor and low-pressure solution. Then to verify the effect of capillary pumping which makes the high and low pressure without a compressor or an electric solution pump in the absorption refrigeration cycle, the evaluation apparatus was manufactured and some experiments were performed to measure the pressure and temperature difference. As a result, it was derived that the pressure difference of 3.3∿7.4 [kPa] and the temperature difference of 4.5∿14 [K] were achieved.
