分离式热管蓄冷空调释冷性能实验研究

Experimental Investigation on the Discharge Performance of Separated Heat Pipe Air-conditioning Systems

本文设计了基于分离式热管换热的蓄冷空调系统,针对其释冷性能进行了因素实验和响应曲面实验研究。结果表明:分离式热管蓄冷空调释冷性能稳定,实验条件下最大制冷量可达5.09 kW;制冷量随循环风量的增加而增加,而除湿量存在最佳除湿循环风量,最佳除湿循环风量约为620 m^3/h,除湿量约为4.32 kg/h;制冷量随环境温湿度的升高而增加;得到了不同工况下制冷量的回归方程,分析了不同影响因子对制冷量的影响规律,在循环风量较低的工况下,热管阀门对制冷量影响较弱,随着循环风量的增加,对制冷量影响增加。

A cold storage air-conditioning system based on separated heat pipe heat exchanger was designed,and the effect of influencing factors on the discharge performance and their response surfaces were experimentally investigated.The results show that the discharging performance of the cold storage air-conditioning system with separated heat pipe was stable;the maximum refrigeration capacity could reach 5.09 kW under experimental conditions.Cooling capacity increases with an increase in the circulating air volume while there is an optimum circulating air volume for dehumidification.The optimum circulating air volume for dehumidification is about 620 m3/h and the dehumidification capacity is about 4.32 kg/h,and the cooling capacity increases with the increase in temperature and humidity of the environment.The regression equation of the cooling capacity under different working conditions was obtained,and the effect of different influence factors on the cooling capacity was analyzed.Under the conditions with low circulating air volume,the influence of the heat pipe valve on refrigeration capacity is weak;however,with an increase in circulating air volume,its influence on refrigeration capacity increases.
