基于吸附制冷技术的小型冷热电联供系统的发展概况

Progress on the Small-Scale CCHP System with Adsorption Refrigeration

本文简要地综述与分析了小型冷热电联供系统和余热驱动吸附制冷技术的应用现状。冷热电联供系统属于分布式能源系统,是充分利用低品位热能的有效手段,系统能源综合利用率高,小型化和微型化是其发展方向;吸附制冷技术作为一种低品位热能驱动的绿色环保技术,应用于小型冷热电联供系统,目前已经成为国际普遍关注的一个学术方向。

A brief survey and analysis is given to the small-scale combined cooling, heating and power(CCHP)system and the present utilization status of the adsorption refrigeration technology in the CCHP system. The CCHP system belongs to the distributed energy system. It is a well-known technology of sufficient utilization of low-grade thermal energy with the principle of thermal cascading, so it has the high primary energy efficiency with the development trend of miniaturization and micromation. Adsorption refrigeration is a type of environment-friendly refrigeration technology, which can be powered by low grade heat. It attracts more and more attention in recent years that adsorption refrigeration is used in the small-scale CCHP system.
