摘要
介绍了太阳能制冷的实现途径和太阳能吸收式制冷系统的研究现状,分析了传统型太阳能吸收式制冷系统的缺点与存在的问题,提出了两种新型太阳能吸收式制冷系统:即在传统的系统基础上增加了压缩式热泵系统(新型A);在太阳能集热器中加入相变蓄能材料,且将热泵系统的蒸发器与太阳能集热器合为一体(新型B)。详细介绍了两种新型系统的工作原理,分析了的系统优缺点。新型系统可以较好利用太阳能实现制冷,能解决传统型系统存在的弊端,为太阳能空调系统的优化提供了新的研究方向。
The realization ways of the solar cooling is introduced, as well as the current research status of solar-absorption refrigeration system. The shortcomings and problems in the traditional solar-absorption refrigeration system are analyzed, proposing two types of new solar-absorption refrigeration system, including model A - system adding a compression heat pump system based on the traditional system; model B - system adding the phase-change energy storage material in solar collector, and com-bining the heat pump system’s evaporator and solar collector together. The working principles of new sys-tems are expounded in details, with analysis on strengths and weaknesses of systems. The new systems can better use solar energy to realize refrigeration, and can solve the drawbacks of the traditional system, pro-vides a new research direction for the optimization of solar air conditioning system.
