文章阐述了分离式热管蓄冷空调系统工作原理,建立了分离式热管蓄冷空调系统实验装置,并对其充冷性能进行了实验研究。该系统的制冷量能够维持稳定,能效比稳定在2.6～3.8之间;系统的蓄冷率可达到55%,其蓄冷量随时间近似成线性增加;热管蓄冷器内介质压力能够稳定在0.4MPa至0.3MPa之间,热管蓄冷器能够稳定运行;热管介质的进口温度能够稳定在-10～-12℃范围,并随着蓄冷过程的进行,热管介质进出口温差越来越小。

The principle of cool storage air-conditioning systems with separate-type heat pipes was stated. An experimental apparatus was built and the experiment on charging performance of a cool storage air-conditioning system with separate-type heat pipes was conducted. The test results indicate that the system could operate steadily and the coefficient of performance was from 2.6 to 3.8. The ice packing factor could reach 55% and the cool storage capacity increased linearly with time approximately. The medium pressure in the heat pipe was from 0.4MPa to 0.3MPa and the medium temperature at the heat pipe inlet was from -10℃ to -12℃. In addition, the difference between the inlet medium temperature and the outlet medium temperature decreased gradually during the cool storage process.
