Does a Window Have to Be Open When Running an Evaporative Air Cooler?

    Evaporative air cooler can lower room temperatures as much as 30 degrees. Forcing fresh air over damp fabric to cool a space is one of the oldest methods of air conditioning. It is easy and effective in dry climates. Even though the principle is simple, you may have questions about how evaporative cooling systems should be run.
     Fundamentals

• Air conditioning cools and recalculates air in a room or in an entire building. It is essential to keep the windows closed so the cooled air does not escape. However, evaporative air  cooler work differently. They pull fresh air into a room, and as it passes over damp pads, it cools the room. As the cool air fills the room, the hotter air is forced out. With really efficient evaporative cooling, a total air change in the space can take place every two minutes.

Varieties

• Evaporative air cooler systems can cool an entire dwelling or a single room. The room units are often placed in windows, not unlike window air conditioning units. In larger systems, duct work and fans together move air throughout the space to allow cool air to enter each room. A simple system uses one duct and fan setup to let in air and blow it into the house.

      Balance

• The purpose of opening a window is to let the warm air escape as the cooler air is circulated by the evaporative cooler's fan. Open the door and a window inside any room you wish to cool so the air can move through. To get a balance of cool air throughout the space, leave both a door and window open in the room to allow air to circulate.

Adjustment

• How much you open a window can determine the evaporative cooler efficacy. Open the window just enough so the door closes very slowly. This means the pressure is balanced, and the hot air is moved through the window as exhaust. If the door slams, the window is not open wide enough. However, don't open the window too far. If the door does not move, the window is too widely open. When the door closes completely, open it and start the process over.

Application and examples of evaporative air cooler

  With the deepening of energy-saving and emission reduction in the globe, energy-saving and emission reduction has deepened into all the aspects of people’s life. Especially the air conditioning refrigeration area is the focus of energy-saving and emission reduction. Evaporative air cooler, which develops fast in recent years, is the outcome of energy-saving and emission reduction time.
   Evaporative air cooler has a history of 60 years in USA. Australia begin to develop evaporative air cooler from 1970s, but it grows fast and best. In the late 1990s, evaporative air cooler was introduced to China, and develops well. Now a great number of evaporative air cooler are sold to abroad every year.
Many areas try to use evaporative air cooler. Especially in hot and dry areas, big difference between dry and wet bulb temperature can be up to 9~15℃ or even worse. In such cases, evaporative air cooler is the best choice for its energy saving and better cooling efficiency.
   In southern China, evaporative air cooler is suitable for factory and production areas with high temperature heat source, including factory of textile, garment, dyeing and tannery, industry of hosiery, chemical, electronic and packing, plant of plastic processing, printing , electro mechanic, hardware, metallurgy and food. In northern China, evaporative air cooler can be used in densely populated public places, such as supermarket, shopping mall, farmer’s market, villa, gym, restaurant, hotpot restaurant, hospital outpatient hall, bus waiting room, song and dance hall, bar, game center, school and auditorium.
   Evaporative air cooler can be used in other places as below.
1. Air-polluted, bad smelling and heavy dust places.
2. Areas that have been installed with air-conditioning but with little fresh air or lack of oxygen gas.
3. Agricultural scientific research base,  training center and  greenhouse
4. Position cooling. In high temperature plants, such as steel works and foundry, workers work in high temperature. Evaporative air cooler can bring fresh and cool air to them by position cooling.
5. Stockyards. Evaporative air cooler helps to avoid plague, improve living rate and reduce disease.
   Below are some installation examples.
