Main points of design for air duct system of air cooler

The evaporative cooler is used to deliver fresh air that has cooled down to the space, and then exhaust the poorer quality air in the space, and then reach the temperature of the lowered space to increase the freshness of the indoor air. Therefore, the cooling system of the air blower is usually closed in one way and one way out. The materials of its air duct are galvanized sheet, and in some cases glass fiber reinforced plastic and plastic air duct are also used.

Place the air outlet where the actual temperature needs to be reduced. The local planned air volume of the air outlet is the local required air volume for its temperature drop. The air outlet standard is determined based on the air volume and the speed of the air outlet. It is usually made of aluminum alloy. Finished products or other finished products such as wood can be selected in a variety of ways depending on the actual situation. Its type can be used in many ways depending on the actual situation, but it is best to use a DC-type four-sided blowing single-layer or double-layer louver; Conditioning valve to adjust air volume.

The standard of the air supply pipe is usually planned by the method of assuming the flow velocity. When planning, it is necessary to save money and make the noise and wind resistance smaller, and the air volume may be larger. Do not bend the air duct too much, so you can reduce the resistance, you can not use the local area of ​​the duct, you must use it, it must be shorter, the pipe is as straight as possible, do not have too many turns and branches, so It will be able to reduce the loss of some local resistance to the system pipeline. The air supply duct and the air conditioner should be connected with a soft receiver, and the air supply duct outside the room should be able to keep warm, and it doesn't matter inside.

If there is a branch pipe at the time of planning, it is necessary to place a valve or branch baffle on the branch pipe to adjust the air volume, so that its air volume and the request meet the planned parameters.
