Owing to the influence of the atmospheric circulation with the different time and space, and the function of the dynamic and heat of the Qinghai Xizang Plateau, it is formed the “cold trough”(low temperature trough) in winter and “Thermal backbone”(high temperature backbone) in the east of China.

Study on wind cooling strengthening process of nodular cast iron;

Heat transfer coefficients of austenitic stainless steel (OCrl8Ni9Ti) and Q235 from 20℃ to 900℃ with shapes of plate and bar were measured under different wind cooling and different wind direction conditions.

When heating procedure and isothermal temperature are not varied,hardness of the forgings of 20CrMoH steel after the annealing will mainly depend on wind temperature and duration of wind cooling during the annealing.

It introduce the structure and principle of the mixed air cooled and water cooled door frame applying the cooling door frame can save energy ideally.

In this paper,the system principle of the air cooled screw heat pump total heat recovery unit was introduced.

Numerical simulation for air cooling vertical falling film absorption of LiBr solution;

The results obtained will be helpful for the development of air cooling absorber.

An air condition scheme is made by comparison in which the air condition system consists of cabinet air conditioner by air cooling direct evaporation and the conditioners are arranged dispersedly.
