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.
