Cassette Air Conditioner

Working of a Ceiling Cassette Air Conditioner

Last Updated: November 18, 2021By Tags:

From a technology standpoint, the ceiling cassette air conditioner is very similar to the traditional air conditioning unit design. The cassette split system differs from the classics because it uses a sub ceiling type internal module rather than a wall type.

However, it is a literal parallel of the classics, including the working principle, design advantages and disadvantages, and installation job characteristics. In this post, we go over all of the elements of a cassette configuration system, including the device, the operating principle, the benefits and drawbacks, and the details of unit installation.

Ceiling Cassette Air Conditioner for Home

Ceiling cassette air conditioner is a two-module method for performing the task of cooling the air to a specific temperature.

Modules that make up the cassette split system are as follows:

  • Interior
  • External

Both components of the system are independent units that are linked together by technical pipes and electrical cables once the system is up and running. You can commonly see the ceiling cassette air-con in small enterprises and office buildings as office equipment. You can get HVAC cleaning Smyrna GA for better cooling.

It’s an unusual occurrence to see it used in houses or apartments. The main source of this scenario is the facility’s need for a false ceiling device, as manufacturers design the indoor module that makes it able to mount under the ceiling.

Indoor Unit Features

The internal component of the AC unit is in the form of a functioning block cassette with a board suited for roof installation. Moreover, a false ceiling should also be present in the roof structure.

The transmission panel stays on the same plane as the false covering, and the functioning block covers up beneath it. The internal cassette unit’s distribution panel consists of several elements:

  • Grille for the Air Intake
  • A Rigid Frame
  • Filter with a Coarse
  • Overlay on the Front
  • Distribution hutters
  • A Filter Ionizer

The middle of the distribution panel is an air intake grille with ionization filters, coarse cleaning, and a robust frame.

You can check the location of chilled air outlet channels around the perimeter, on the sides of the same distribution panel, and the support by shutters with automatic cycle control valves.

A light indication board and remote control are located on the front cover of the cartridge’s distribution panel. 

The refrigeration design includes a fan, a condensate drain, an evaporator, receiving appropriate units from the external module, and an integrated power board, which hides beneath the ceiling. So, get the Commercial air duct and dryer vent cleaning Smyrna GA for offices.

External Module Structure

This aspect of the cassette air conditioner’s design is identical to the original form of home air conditioning systems.

The block alley module has the following elements inside it: 

  • Compressor
  • Automation Elements
  • Fan
  • Capacitor
  • Electrical Parts

A freon-charged refrigeration circuit combines a compressor and a condenser. Manufacturers establish interconnections through a pair of straight shut-off switches for connection to the air handling units.

The external module’s power lines for automatic control and compressor power likewise output to the internal module’s contact panel. So, here they switch according to a specific design and output to the general power supply.

Working of a Cassette System

In fact, the basic principles of operation of a traditional cooling system remain unchanged. However, refrigerant is sourced from the most often used brands in practice.

So, if the cassette system is entirely built by merging the exterior and internal modules, the system circuit gets charged with this chemical. We suggest that you become familiar with the complexity of self-refilling Freon systems.

However, the compressor circulates the freon within the loop after turning on the cassette split system and operating it. Its circulation causes the condenser to cool.


The fan brings air in it, and the air intake grille sucks it through the evaporator. You can find it in the cassette housing of the interior unit. However, the fan supplies the air to the exit through shuttered side channels that the evaporator has cooled.

The outgoing part of the side channels bends by around 30-35 degrees, which is a unique design. As a result, the cooling airflow from the cartridge’s tubes moves directly to the sides rather than vertically downward.

Here, the flow of air surrounds in four directions due to the existence of channel outputs on all four sides of the distribution board.

Advantages of Cassette Models

The consistency of the air distribution of the airflow over the size of the room is a clear advantage of cassette split systems.

Furthermore, the manufacturer ties the major component by installation standards. It stipulates that you can install a ceiling cassette entirely in the room’s center.

It is possible to more efficiently chill the rooms to the appropriate temperature due to the optimal placement. You can do it with the help of the cartridge and the same optimal air circulation.

The architectural element is also an advantage. When it comes to design organization, cassette modules make it easier than traditional split systems that use wall-mounted internal modules.

Furthermore, the manufacturers place the cassettes into the ceiling and are frequently used as aesthetic features that add to the overall charm. It is particularly noticeable in the structure of the office and building structures.

Technology Flaws

Cassette air conditioning systems have inherent and significant flaws. Mounting limits are an example of one of these glaring flaws. However, it has the ability to only install equipment in areas with a false ceiling.
