Installation of air conditioners: cassette, duct, industrial - installation stages

Cassette air conditioners

A cassette air conditioner is a type of split system that is installed in the ceiling and distributes cooled or heated air through special openings located along its perimeter. These air conditioners are often used in offices, retail spaces, hotels and other commercial premises.

Cassette air conditioners are popular in areas with large and open spaces where uniform air distribution and maintaining a certain level of comfort are important.

Stages of installation of a cassette air conditioner

Correct installation of a cassette air conditioner requires professional skills and compliance with all technical requirements to ensure reliable and safe operation of the system.

  1. Determine the optimal location for installing the indoor unit in the suspended ceiling, taking into account the location of furniture and ventilation holes.
  2. Drills, hammer drills, screwdrivers, a level, fasteners, insulating materials and pipelines for freon are required.
  3. A hole of the appropriate size is cut in the suspended ceiling to install the indoor unit.
  4. Fixings are secured to the main ceiling structure to support the weight of the unit.
  5. The indoor unit is lifted and placed on the mountings, then locked in place.
  6. Connect the indoor unit to the outdoor unit with using copper pipes for freon, having previously insulated them.
  7. Install a drainage pipe to remove condensate, ensuring the correct slope for water flow.
  8. Connect electrical cables between the indoor and outdoor units, observing safety requirements
  9. Choose a location on an outside wall, roof, or ground that provides good ventilation and access for maintenance.
  10. Install brackets or platform for the outdoor unit.
  11. Lift and fix the outdoor unit on the fasteners.
  12. Connect the freon pipes, drain pipe and electrical cables between the indoor and outdoor units.
  13. Remove air and moisture from the freon pipes using a vacuum pump.
  14. Remove air and moisture from the freon pipes using a vacuum pump.
  15. Remove air and moisture from the freon pipes using a vacuum pump.
  16. Remove air and moisture from the freon pipes using a vacuum pump.

  18. Fill the system with freon to the required level.
  19. Check connections for leaks to prevent freon leaks.
  20. Turn on the system, check the operation of all functions of the cassette air conditioner and make the necessary adjustments.

Complete installation and testing

Install the decorative grille on the indoor unit to complete the installation. Check the operation of the air conditioner in all modes, make sure there are no vibrations, noise or leaks. Explain to users the operation and care of the cassette air conditioner.

Duct air conditioners

Duct air conditioners are a type of air conditioning system in which cooled or heated air is distributed through a network of ducts hidden in the ceiling or walls . They are used to create a comfortable microclimate in rooms for various purposes, ensuring uniform air distribution.

Duct air conditioners provide high efficiency and comfort, which makes them a popular choice for various types of buildings and premises.

Stages of installation of a duct air conditioner

Correct installation of a duct air conditioner requires a professional approach and compliance with all technical norms and standards to ensure efficient and reliable operation of the system.

  1. Creation of a detailed plan for the location of indoor and outdoor units, as well as air duct routes
  2. Purchase the air conditioner, ducts, fasteners, insulation materials, electrical cables and other necessary components.
  3. Ensure that the location for installing the air conditioner and laying the air ducts is accessible and ready for installation.
  4. The indoor unit is usually placed in a suspended ceiling or technical niche.
  5. Installing fasteners and fixing the indoor unit in place. It is important to use a level for accurate placement.
  6. Installation of air ducts from the indoor unit to indoor ventilation grilles. Ducts should be insulated to prevent heat/cold loss.
  7. Place and secure grilles on walls or ceilings to distribute air evenly.
  8. Make sure all duct connections are sealed to prevent air leaks.
  9. The outdoor unit is installed on an outside wall, roof or on the ground in a place with good ventilation.
  10. Installing brackets or a platform to fix the outdoor unit.
  11. Lift and secure outdoor unit in place.
  12. Connect the indoor and outdoor units with copper pipes for refrigerant circulation. The pipes must be insulated.
  13. Ensure the correct slope of the drain pipe for the outlet
