Flexible duct and corrugated pipe for floor standing air conditioner

The principle of operation of an outdoor climate system, providing for the installation of a branch corrugated pipe, differs from the principle of operation of a split system. A flexible air duct for a mobile air conditioner is both a positive and a negative feature: on the one hand, it is possible to transport the unit, on the other, you need to find a way to bring the corrugation to the street. On this occasion, disputes and creative proposals do not subside - which method is the best and most reliable.

Why do you need a corrugation and is it possible to do without it

The device and principle of operation of a mobile air conditioner

To answer the question, you need to understand the models of floor standing air conditioners. They come with and without an air duct. Both units have their pros and cons:

  1. Mobility is greater for the model without corrugation - it is moved with the help of wheels and installed anywhere in an apartment or house. With a corrugation, mobility is limited - a maximum of half a meter in different directions, while it cannot be lengthened, as this affects performance. The line increases, the compressor is forced to work harder to cool the room. If there is no temperature sensor, the compressor power will be spent on a longer corrugated pipe.
  2. For the model without corrugated pipe, there is no need to look for an opening to get the air out. In this case, the efficiency of the device decreases, since the temperature in the room increases due to the operation of the compressor (it generates heat). Cooling is felt near the floor-standing unit, it may not be enough for the whole room. The humidity is higher for models without an air pipe. In air conditioners with corrugated air, humid air is removed, but the problem of where to lead the tube remains.
  3. The disadvantage of both models is the increased noise during operation, since the main components, including the compressor, are located inside the room.
  4. A positive feature of both air conditioners is the ability to transport the units to another place to work. For example - to the dacha.

Corrugation for floor air conditioner - the ability to reduce the humidity in the room, while maintaining a comfortable temperature in summer in the heat.

How to choose a corrugated pipe for a monoblock floor

Usually the air duct for the air conditioner comes with the equipment, and you do not need to select it yourself. The problem arises if the following happens:

  • damage to the part;
  • loss or theft;
  • you need to lengthen the pipe for certain reasons.

If damaged, the tightness of the structure is violated, warm air will return through the holes into the apartment. Therefore, the pipe must be replaced with a new one.

It is necessary to lengthen the air duct in the following cases:

  1. The air conditioner model has too short corrugation, and the window or vent is high. You need to either install the monoblock on a dais, or lengthen the corrugation. At the same time, the power of the device decreases, because the volume of exhaust air increases. On the forums, they propose to install additional pumps that will help remove warm flows, but for this you need to have knowledge and skills in order to independently select a pump and carry out the installation.
  2. The only place for attaching the corrugation is the balcony, but there is a loggia in front of it and the pipe does not reach the window. The loggia is large and will take in most of the cold air produced by the equipment.As a solution to the problem, it is proposed to partially lengthen the corrugation, and to extend the part of the pipe adjacent to the air conditioner as much as possible so that the volume of exhaust air does not increase significantly.

To choose the correct model of the air conditioner, you need to calculate in advance the distance from the proposed installation site of the monoblock to the pipe outlet - it can be a door, a window, a window, a sandwich panel at the bottom of a balcony door, a wall.

Where to bring the corrugation from the monoblock - suggestions and reviews

Conducting corrugation into an open window is the easiest, but least effective way

The easiest way is to make a hole in the sandwich plate. It cuts well, but you need to have special tools. The equipment comes with an insert that is attached from the outside - it holds the pipe and creates a sealed connection, preventing warm air from entering the room. The problem is that in winter this hole will let the cold through and will need to be closed. On sale there are removable frames in the frame, which can be removed if desired. This is a rather expensive thing, since manufacturers charge money for convenience.

You can cut a hole to the diameter of the pipe in the glass and fix the holder from the outside. This is done both on double-glazed windows and on single glass. This design works well in the summer, but in the winter it also needs to be covered to keep the room cool. If the monoblock works for heating - another matter. This will be his permanent location. The solution is offered as follows:

  • have two double-glazed windows and change them depending on the season;
  • replacing glass for summer with a sandwich plate and making a hole in it is the most aesthetic solution;
  • output through a slightly opened window or open window, but in this case, the cooling will not be effective, because warm air will penetrate through the gap.

The next option is not to touch the glass, but to make a hole in the wall exclusively for the monoblock. It all depends on the thickness of the building material - concrete, brick. Special tools are needed to make a hole with smooth edges and not damage the structure. Some people on the forum are familiar with the new diamond drilling technology, which is capable of cutting even reinforcement in concrete, which is applicable for load-bearing structures. For ordinary walls, use a punch or percussion drill.

The price of the work is high, but in the absence of other options, you will have to pay. Drainage in the absence of a special tray can be led out into the same hole.

An air vent in the wall has its drawbacks. One of them is the intake of cold air during the winter season. On this score, it is suggested to use mineral wool and close the hole in the wall with it. Acceptable, but not aesthetic option. It is allowed to violate the integrity of load-bearing walls on an individual basis, first you need to obtain permission from the architect. Otherwise, you will have to pay a fine and make repairs at your own expense.

How to properly build up a corrugation for a monoblock

Corrugation mounted in single glass

To compensate for the pressure loss as the duct length increases, the following measures can be taken:

  1. Extend by no more than 1 meter, while leaving the same diameter as the main pipe. If this is enough to bring the corrugation out, the losses will be negligible.
  2. Leave a piece of corrugation of a standard diameter, attaching a thinner but long tube to it through an adapter. It should be borne in mind that the volume of air passing through the pipe is from 230 to 260 liters. Air resistance is higher in circular ducts than in square ducts.

It must be sealed to the outside of the glass or wall. To do this, use dowels, which are used to screw on a plastic or iron nozzle that holds the corrugated pipe for the floor air conditioner.

If you do not want to pay for the installation of a special insert, you can independently connect a corrugated hose, using the experience of people who already have monoblocks.
