| Abstract: | Taking the practice of domestic renovation of air conditioning system on vehicles of Guangzhou metro line 3 as an example, an analysis and comparison of the advantages and disadvantages of the originally made air conditioning system and the present domestically made air conditioning system is carried out. With re-design of air conditioning compressor and cooling system, two independent systems to replace a system, the energy efficiency is enhanced, and ride comfort is improved. Through re-design of the drainage structure and reducing the front and rear diferential pressure of evaporator, the problems of condensate and stagnant water and air blown with water in the blowing chamber are solved. |
