摘要
Abstract
A new absorption refrigeration circle is proposed, which takes NH3-LiNO3 as the working fluids, compresses the refrigerant vapor out of evaporator and is driven by solar energy. The COP, exergy efficiency, the ratio of the electricity to heat and the flow rate of the cooling water in the proposed circle is numerically studied. The results reveals that: taking electricity about 0.7 to 10.68 percent of the solar energy can reduce 16 to 22 °C of input temperature of the driven water from 95 ℃; the COP is between 0.495 and 1.201 while the exergy efficiency is between 0.245 and 0.122; the flow rate of cooling water will be decreased linearly from 7.24kg/s to 3.74kg/s with the decrease of the temperature of driven water. This circle overcomes the shortage that the traditional solar cycle is subjected to the fluctuation of solar, so it has good energy efficiency and practical value.关键词
