一、前言在热能利用中,热泵技术是有前途的领域。热泵以节约能源为目的,提高了废热回收的效果及经济效益。目前,遍及世界的、温度在70~80℃之间的大量废热仍未开发利用。其它普遍存在的低温热源即太阳能、地热能也仍未充分利用。在低温废热回收技术中,单一热源运行的吸收式热泵系统大有发展和应用的前途。废热
I. INTRODUCTION In the use of heat energy, heat pump technology is a promising area. The purpose of heat pump is to save energy, improve the effect of waste heat recovery and economic benefits. At present, a large amount of waste heat throughout the world, with temperatures between 70-80°C, has not yet been exploited. Other ubiquitous low-temperature heat sources, namely solar energy and geothermal energy, have not yet been fully utilized. In the low-temperature waste heat recovery technology, a single heat source operated absorption heat pump system has great potential for development and application. Waste heat
