cassette air conditioner

How is the installation of a cassette air conditioner carried out?

There are several types of air conditioners on the market. Among them, it is difficult not to notice a cassette air conditioner. Despite its compact size, this device is able to effectively cool a room with an area of more than 100 square meters! It is not surprising that «kassetnik» has gained its popularity in offices, gyms and shops.

In this article, we will tell you in detail what a cassette air conditioner is, what are its advantages and disadvantages, how the installation of a cassette air conditioner is carried out and what needs to be taken into account so that the device will serve you for many years.

General information

A cassette-type air conditioner consists of one outdoor unit and one or more indoor units. The outdoor unit looks the same as the split system. This is a rectangular metal box with ventilation grilles. It is mounted on a horizontal or vertical surface (for example, on a facade or a flat roof).

The internal block looks like this:

It is attached to the ceiling, and subsequently communications are sewn up with hinged panels. For this reason, cassette air conditioners are rarely found in houses and apartments, since suspended ceilings are strongly associated with the» office » style. Most often, a cassette air conditioner can be found in commercial premises: offices, sports clubs, shops, restaurants, etc.

The outdoor and indoor units are connected to each other using electrical wires and pipes through which freon circulates, as well as a network of air ducts.

The indoor unit, being under the ceiling, does not take up much space. Also, thanks to this arrangement, air flows move around the room more efficiently, without creating drafts. The device is controlled remotely using a remote control.

However, it is important to take into account that for a full-fledged installation of a cassette air conditioner, it is necessary to «borrow» up to 50 cm of space above your head. If the room has low ceilings, a cassette air conditioner will only aggravate the situation.

Fortunately, manufacturers have come up with more compact models with thin internal blocks that take no more than 25 cm. This option may be more acceptable for rooms with low ceilings. But remember that such devices do not have the greatest power, and are designed for small rooms.

Technical features

Cassette air conditioners of various capacities are presented on the market: from 3 kW to 20 kW. The latter can be safely called industrial, since such devices are able to cool a room with an area of up to 170 sq. m. Competent selection of power is the key to effective operation of the device. However, we will talk about the choice a little later.

Let’s return to the varieties. In addition to the power, cassette air conditioners are divided according to the number of threads: one-, two-, three-flow, etc. The more streams, the better for large rooms. In a small office, a single-threaded device is enough.

Cassette air conditioners can be square and rectangular. Standard sizes:

  • 60×60 cm, 60×70 cm

  • 60×70 cm, 70×70 cm

  • 60×90 cm, 90×90 cm

  • 70×90 cm, 70×120 cm

  • 60×120 cm, 90×120 cm

The devices are equipped with filters for air purification, temperature sensors and blinds for adjusting the direction of air flows. As for the functionality, everything is in order here at the «cassetnik»: the devices can boast of cooling, heating, ventilation, low power consumption, timer, etc.

As we said earlier, cassette air conditioners are controlled by a remote control. It can be either a wall-mounted or a separate battery-powered remote control. The controls are largely intuitive, especially if you know English. Before using, read the instructions to properly configure the device according to your wishes.

Advantages and disadvantages

Cassette air conditioners can boast of many advantages:

  • High power, thanks to which one cassette air conditioner is able to maintain a comfortable microclimate in large rooms;

  • Work efficiency, thanks to which the air cools/heats up really quickly;

  • Saving space on the floor and walls, because the indoor unit is installed on the ceiling;

  • Low noise level, which will not interfere during working hours;

  • A favorable combination of price and power, you can buy one «cassette player» instead of several split systems.

The main disadvantage of a cassette air conditioner is the limited installation. The device can be installed only in a high room paired with suspended ceilings. Because of this, «cassette players» are not often found in standard Soviet apartments. And a suspended ceiling can hardly be called an aesthetic solution for a living room.

As you can see, there is only one minus. However, you need to pay special attention to it, so that you do not regret the time and money spent later.

Choosing a cassette air conditioner

Earlier, we have already mentioned some of the features of choosing a cassette air conditioner. Let’s take a closer look at this issue.

Pay attention to the following features:

  • The size of the room

We have already discussed this earlier in the article. BE sure to take into account the height of the ceilings and the area, carefully measure the dimensions of the room. There are situations when at this stage it turns out that the room is not suitable for the installation and proper operation of the «cassette player». You have to choose a different type of air conditioner. It is better to find out this even before buying the device;

  • Power of the air conditioner

If the size of the room allows you to install a cassette air conditioner, you should take care of selecting the power of the device. The standard calculation looks like this: 1 kW = 10 sq. m. However, this formula cannot be called universal. A competent sales manager should make a more detailed calculation taking into account the data that you will receive after measuring the dimensions of the room;

  • Type (inverter/non-inverter)

Non-inverter air conditioners were widespread in the last century, but they can still be found on the shelves. Such devices are cheaper, but they are uneconomical and emit an increased noise level. If you want silence and are worried about electricity bills, it is better to buy an inverter cassette air conditioner.

Also

A few words about self-installation. A cassette air conditioner costs a lot of money, so it’s not surprising that some buyers want to save on installation. We strongly do not recommend mounting the «cassette player» yourself, if you do not have sufficient experience and qualifications.

Believe me, it is better to spend once on a high-quality installation and then enjoy the operation for many years than to deal with breakdowns, spending your time and money on them. Sometimes the consequences of poor-quality installation cost the owner more than an initially competent installation from professionals.

Next, we will tell you how professionals install a cassette air conditioner. This is not a guide to action, the information is provided for informational purposes.

Installation

To begin with, we will outline the main features of the installation, and then we will talk about the specific stages of the work.

Installation of a cassette air conditioner begins with the selection of a place. The optimal location is in the center of the room. So the air flows will circulate quite efficiently, while not causing discomfort to people. The device and communications are installed directly on the rough ceiling, which is then closed with hinged panels.

The distance between the ceiling and the curtain panels is usually from 25 to 50 cm. In this case, the indoor unit is installed in such a way that its front part is flush with the finished ceiling. The decorative grid of the indoor unit is fixed at the very last moment, after the repair is completed (if it was carried out).

In details

Installation stages:

  • Installation of the outdoor unit

The outdoor unit can be installed vertically on the facade of the building or horizontally on the roof/blind area. In all cases, a special bracket is used. It must be strong and reliable, made of high-quality steel;

  • Laying of communications

In a good way, a separate article should be devoted to this topic, since it is quite extensive. In short: electrical cables, air ducts and copper pipes are laid from the outdoor unit to the intended installation site of the indoor unit. The length of communications is always calculated with a margin. Communications are attached directly to the draft ceiling on special suspensions;

  • Installation of the indoor unit

The indoor unit is mounted in the designated place between the metal guides or on the suspensions. Communications and a drainage pipe are connected to it, which will subsequently divert excess condensate outside the air conditioning system;

  • Launch and testing

After installing the cassette air conditioner, it is filled with a refrigerating agent (freon) and the first start is carried out. Next, the device is thoroughly tested: the master turns on each operating mode in turn and checks the overall performance of the air conditioner;

  • Installation of a suspended ceiling

If the air conditioner is installed in a room with a rough repair, after installing the device, you need to mount the suspended ceiling. Air conditioners rarely do this, except for an additional fee. Therefore, we will not talk in detail about this stage.

Terms of use

In order for the air conditioner to last for many years, it is necessary not only to install it correctly, but also to use it correctly. Air conditioning systems consist of many components that need attention. The device must be regularly serviced, cleaned of dirt, refueled.

Usually these works are entrusted to the same company that installed the air conditioner. Theoretically, you can carry out part of the maintenance with your own hands, but the device is at a high altitude and sometimes you have to remove some of the hinged plates to get to the right parts of the system.

Therefore, we recommend that you entrust the service to professionals. Clean and check the device at least twice a year: before the use season and after it. If you additionally operate the air conditioner in the fall or spring, service it at least 3-4 times a year.

Results

A modern cassette air conditioner is a powerful, quiet and functional device that quickly gained its popularity in commercial premises. It does not take up space on the wall or floor, effectively cools and heats the air, and is also able to work in large rooms with an area of more than 100 square meters.

Installation of a cassette air conditioner should be trusted only by professionals. And do not be afraid of the prices for such services. Often, a high-quality installation, on the contrary, saves you money, since it reduces the risk of breakdowns.

Also, do not forget about regular maintenance of the device. «Cassetnik» needs high-quality cleaning and performance testing, its service life and work efficiency largely depend on this.
