The combined air -conditioning crew can be divided into: general universities, new groups, variable air volume units, purification units, etc.Due to different uses, various combined air -conditioning units can be composed of different functional sections (air mixing, equal flow, filtering, cooling, first and secondary heating, humidification, delivery, intermediate, water spraying, sounding sound, etc.).Construction installation points 1. Combined air -conditioning units can be installed on the base of concrete platforms or steel -made steel.The height from the ground should ensure that the condensation water is discharged smoothly.There should be a drainage ditch (tube) and floor drain to eliminate condensate water and put water on the bottom of the air -conditioning machine.2. On -site assembly air -conditioning units should be paid attention to: 1) sealing of the four corners of the unit, the bottom plate, and the maintenance door; 2) the quality of the sealing material.3. Check the cooling section and the lower part of the dripping section of the spray section before installation.4. Check whether the thickness of the insulation layer of the unit meets the requirements, whether the pavement of the thermal insulation material is uniform, and whether the cold bridge appears at the connection between each functional section to prevent the shell from exposed.5. Check whether the insulation materials of the unit meet the fire prevention requirements. The insulation material should be difficult or non -combustible materials, and the approval certificate of the competent fire protection department shall have a certificate of approval.6. After the unit is installed, check whether the wind speed distribution of the section should be evenly distributed.Whether there is water with water after the cooling disk or water spraying section.Try to avoid the emergence of this phenomenon.
The above is the precautions for the construction and installation of the combined air -conditioning unit. I hope that the above content can be helpful to everyone.
