Researches of the temperature field and velocity field in the passenger compartments of the air-conditioned high-speed train are the foundations of design of airflow organization and evaluation of comfort within the passenger compartments of the air-conditioned high-speed train.

Research on the fuzzy control of train air-conditioning based on PMV index;

Research on energy-saving of train air-conditioning based on PMV index

Study on variation of temperature during the operation of air-conditioned train;

By establishing mathematical model, and applying the PID control, we have an emulation trial to the concentration of CO2 in air-conditioned train at the environment of SIMULINK, to keep the concentration of CO2 at the given concentration, achieving the aim of controlling fresh air.

Based on the actual condition of air-conditioned train, this paper designes questionnaires about IAQ intrain compartment and investigates the IAQ by the questionnaires.

Study on the application of R407C refrigerant on train air conditioning;

In the paper, the situation of train air conditioning at present is introduced, then the frequency control of speed for train air conditioning is analyzed, and the advantages of frequency control of speed being used in train air conditioning is put forward, such as save energy and suitability.

But nowadays in our country, train air conditioning aise not very common, and the standard design materialsi are not available.

After analyzing the data, it puts forward the recommend values of temperature and humidityfor the air-conditioning train that meet the passengers require of thermal comfort.

However,this method is fit for evaluating the indoor air cleaner,and not for evaluating air cleaner in air-conditioning train.
