摘　　要：本研究设计制作了一款充气式PVC帐篷,在冷库测定帐篷内外温度及综合传热系数,并探究帐体表面敷设铝箔对帐篷保温性能的影响。实验结果表明冷库温度-10℃,帐篷内部加热送风功率500 W时,帐篷内平均气温可达17.1℃,操作温度13.1℃,综合传热系数1.267 W/(m^(2)·℃)。当帐篷内部加热功率一定时,冷库温度对综合传热系数无明显影响。当冷库温度不变时,加热功率越高,测量得到的综合传热系数越高。帐篷表面敷设铝箔能够提高保温性能,效果排序为内外敷设优于内敷设优于外敷设,内外表面敷设铝箔后综合传热系数可降至0.914 W/(m^(2)·℃)。A prototype PVC inflatable tent was designed and manufactured. The inside and outside temperature, the equivalent heat transfer coefficient were measured and calculated in a cold storage laboratory. The influence of aluminum foil coverage on the thermal performance was also studied. The experimental results show that with an ambient temperature of -10 ℃ and an internal heat source of 500 W, the average temperature inside the tent was 17.1 ℃. And the operative temperature reached 13.1 ℃. Meanwhile, the equivalent heat transfer coefficient was 1.267 W/(m^(2)·℃). When the internal heat source power was constant, the ambient temperature had no significant effect on the heat transfer coefficient. Meanwhile, with a certain ambient temperature, the higher the internal heating power was, the higher the heat transfer coefficient could reached. The thermal insulation performance of the tent could be improved by the aluminum foil coverage effectively. The improvement with aluminum foil coverage on both surfaces was demonstrated by a heat transfer coefficient decrease to 0.914 W/(m^(2)·℃), which was greater than coverage on interior surface, and even greater than coverage on exterior surface.
