A simple model to calculate the defrosting electrical energy input and the ways to optimize the air cooler s electro-thermal defrosting system;

The air cooler made of supersonic atomizer can produce smaller water particles and exchange heat more easily, so it has higher efficiency of reducing temperature by gaining more heat of vaporization in the unit time.

Investigation of the Frosting Performance and Improvement of the Defrosting Method for an Air-cooler under Low Temperature Condition;

The theoretical analysis and the mathematics model on air-cooler s frosting performance are provided in this paper,based at a frozen room in Xinyang area.

The mathematical model was proposed in this paper on the frosting performance of an air-cooler in one freezing room of a poultry enterprise in Huazhong area.

The purpose of this investigation is to study the regularities of frost growth and distribution along the fin pipes and the changes of air flow rate and pressure drop through unit cooler.

So much convenience can be gained by using the program to optimize the unit cooler’s configuration in the future.

Distribution characteristics of fog droplets from air-cooling fan;

Analyses the characteristics of air cooling chillers that require no cooling tower and cooling water system and just consume similar amount of energy to that by water cooling chillers.

The voltage stabilizing means in the quench air fan frequency converter speed regulating control system were introduced in detail.
