Simulation and analysis of absorption heat pump system based on renewable energy

基于对可再生能源利用的考虑和热泵热源温差的协调配置的研究,文中选择氨水吸收式循环,将太阳能与地热两种可再生能源结合,提出了一种具有制冷与供热功能的组合热源新热泵系统。通过对新系统的过程模拟,文中研究了新系统的能量特性和热力学的机理;讨论了热源温度对系统制冷、供热效率的影响规律。研究表明新系统具有更高的能量利用特性,并验证了氨水吸收式循环同时采用太阳能和地热的可行性。

Based on researches of the renewable energy use and reasonable temperature matching for heat pump, this paper proposes a new heat pump system with a heat-source combination for refrigeration and heat-supply, by choosing an ammonia absorption cycle and combining solar energy and geothermal heat. The performance of the new system is simulated, and the influences of heat-source temperature on the performances of refrigeration and heat-supply are discussed.
