Operation principle of Air Cooler KT-18DS

The cooler operates under the principle of evaporation. The process treating temperature-humidity between water and air is happened in the space of machine room by axial fan with large air flow, cooling pad and water pump. Fresh and cool air in the machine room wil be pumped into workshop by axial fan through the system of wind pipeline. Dry and hot air and dust inside workshop is pushed out by differential pressure.The cooler has small and tidy composition with the system of air pipelines leading fresh and cool air into the area needing to be made cool. For this reason, we can apply to make cool air for total workshop or a part of workshop.

The cooler has side outlet and it includes the following main parts:

–          Cover of the cooler: it is made of PP plastic protecting it from harsh condition of weather and ultraviolet rays;

–          One axial fan including three or nine blades like kestrel’s wing and large airflow;

–          Three frames of evaporative cooling pads (model 5090) at three sides and attaching cleansing wind net;

–          Three sets for dividing and distributing water for three frames of evaporative cooling pads;

–          One water pump: supplying water for frames of evaporative cooling pads;

–          One automatic valve for supplying water and one automatic valve for letting out;

–          One set of power and electronic control;

–          The bottom of the cooler: containing water and put together equipments.

The cooler has top outlet and it includes the following main parts:

–          Cover of the cooler: it is made of PP plastic protecting it from harsh condition of weather and ultraviolet rays;

–          One axial fan including three or nine blades like kestrel’s wing and large airflow;

–          Four frames of evaporative cooling pads (model 5090) at four sides and attaching cleansing wind net;

–          Four sets for dividing and distributing water for four frames of evaporative cooling pads;

–          One water pump: supplying water for frames of evaporative cooling pads;

–          One automatic valve for supplying water and one automatic valve for letting out;

–          One set of power and electronic control;

–          The bottom of the cooler: containing water and put together equipments.

The typical methods of installation:

Floor standing installation	Wall mounting installation	Mobility with high mental base
Mobility with low mental base	Hanging installation

1. Evaporative air coolers having large capacity and airflow;
2. Pipelines lead fresh and cool air into a workshop;
3. Diffuse shutters: Distributing fresh and cool air into a workshop;
4. Supports and machine platforms;
5. Circulative tanks;
6. Water pumps: Supplying water for  evaporative air coolers;
7. Electric box: Controlling equipments of the system;
8. Electric equipments and material.

Evaporative air coolers are installed steady arrangement on all space of a workshop ( making fresh and cool air for all space of the workshop) or only installed to concentrate on parts of the workshop where employees do their works (making fresh and cool air for parts of the workshop). As a result, this system saves investment expenses and electric consumption, but it still makes clear and cool working environment.

When the system of evaporative air coolers operate, water will evaporate into air to decrease air temperature partially, the rest of water return to continue a new circulation, simultaneously, volume of water is also supplied additionally to compensate for partial water evaporating. That is the circulation of water in this system, it helps us to save water and other expenses. Moreover, because volume of water is changed regularly, it helps the system to operate more effective and air flow blowing into the workshop to become cleaner and cooler.

The most salient feature of the system of evaporative air coolers making positive pressure:

• Low expenses of investment and operation: Its investment expenses and electric consumption is correlatively equal 30% and 10% to the system of air conditioners.
• High effect: Air through the coolers will be cleansed and made cool to become abundant oxygen. As a result, the coolers will make ideal environment to increase productivity and guarantee health for employees.
