| Abstract: | Introduce the research situation and application of the use of air conditioning heat pipe heat exhaust air recovery in train air-conditioning. Analysis the working process of RW25T train air-conditioning and the heat pipe heat exchanger applied to heat recover from exhausted air. Use the thermal simulation software Icepak to simulate the summer working condition. Get the heat recovery efficiency of the heat exchanger and amount of heat recovery with the inlet wind speed through the pre cool temperature of fresh air under different inlet wind speed. Demonstrate the feasibility of the heat recovery device. |
