What is a ducted ceiling air conditioner? What are the outstanding advantages?

Air conditioners have long been an indispensable appliance in every home. Today, ducted ceiling air conditioners have gradually become more popular and closer to consumers. So what is a ducted ceiling air conditioner and what are its outstanding advantages? Let’s find out with lassho.edu.vn!

What is a ducted ceiling air conditioner?

Duct-connected ceiling-mounted air conditioner (or duct-mounted ceiling-mounted air conditioner) is an air conditioner with a mechanism to blow cold air through the ducts , usually installed on the ceiling or in the ceiling without exposing the machine.

This machine is especially capable of operating with a large capacity , so it will create a superior cool space. For that reason, ceiling-mounted air conditioners are often located in large spaces: hotels, supermarkets, commercial centers, halls, …

Structure and working principle of ducted ceiling air conditioner

Outdoor

The outdoor unit of the air conditioner is placed outdoors to radiate heat directly to the environment. With a large compressor capacity (from 16,000 BTU or more), this series is suitable for installation in large spaces.

Structure of the outdoor unit:

• Cooling fan: there are cooling fans for the outdoor unit.
• Compressor: the most important part has the function of compressing gas, generating work to reduce the temperature of gas.
• DC motor: the supporting part to increase the efficiency of the compressor.
• Inverter: helps control the capacity of the outdoor unit.
• Throttle valve: component associated with the compressor to control the flow of gas in the air conditioner.

Cooler

For this model, the indoor unit will be hidden inside the ceiling and the wind will be exposed to the outside. At the same time, the machine also has multiple outputs and each end will combine with 1 air duct. The capacity of the machine will determine whether the machine can connect more or less ducts.

Structure of the indoor unit:

• Ventilation: There are rectangular holes mounted in the ceiling for cold air to circulate to the room.
• Flexible ducts: a system of pipes placed under the ceiling to conduct cold air from the gas pipes to the vents.
• Wind box: the sound absorber for both the indoor unit and the distribution of cold air to the ducts.
• Refrigeration unit : includes the controller, copper pipe coils directly connected to the compressor in the outdoor unit, a small fan and condensate plumbing.

Working principle

Duct-connected ceiling air conditioners have a working principle that is mainly based on the circulating cycle of gas flowing in copper pipes.

• First, the compressor will cool the gas in the outdoor unit, then it is transported to the copper pipe system and to the indoor unit.
• Through the process of moving, the gas continues to be cooled to a temperature of about 6 – 10 degrees. At that time, the air around the copper pipe system in the indoor unit will quickly decrease in temperature.
• Finally, this cold air will be blown by the fan through the air box and then through the duct and air outlet to reach the room to be cooled.

Advantages and disadvantages of ducted ceiling air conditioners

Advantage

• Space saving: the design is completely recessed in the ceiling, only the vents carrying cool air are exposed, so this system will save considerable space.
• Increase aesthetics: the design is highly aesthetic because the pipe shaft is hidden, and the machine is built into the wall.
• Good cooling ability: creating cooler air than conventional air conditioners due to its large capacity. In addition, because it can be connected from many vents, it ensures even cooling.
• Stable operation: This series of machines produced by big brands like LG is usually less damaged, stable, smooth and durable.
• Wide operating range: ducted ceiling air conditioners will cool the entire space through the duct system, even if there are many different rooms.

Defect

• Does not cool completely: does not produce cool air like Multi air conditioners because they are often placed in large spaces, so the model is only suitable for cooling the air.
• High cost of installation and maintenance: because there are many air vents and many locations, the repair and maintenance costs of this air conditioner are more expensive and the maintenance process is also more complicated.
• The deodorizing air filter system is not as good as the wall-mounted air conditioner : the air is divided into the vents, so the deodorizing performance will be much limited.
