What are air conditioners without outdoor unit

In the collective imagination, the air conditioner has always been seen as a device consisting of two units: the indoor and the outdoor unit. Over the years, the indoor split has undergone numerous evolutions, both in terms of technology and design.

Many brands today offer it as a piece of furniture, with sinuous lines and inconspicuous details. The problem, if you want to call it that, is the outdoor unit, also known as the compressor. Often cumbersome, certainly not attractive in terms of aesthetics, and sometimes also difficult to position outside buildings.

In recent years, solving the age-old problem of the outdoor motor has become possible thanks to air conditioners without an outdoor unit. In these devices, the motor is basically integrated in the interior block, with only an outlet for the hot air pipe having to be created.

The same mechanism as portable air conditioners, but with a double advantage: less noise, and performance equal to that of fixed air conditioners.

How AC without outdoor unit works

Air conditioners without an outdoor unit work essentially in the same way as air conditioners with two units. The difference lies in the presence of the compressor inside the split that communicates with the outside through the two holes drilled in the wall.

A mechanism, therefore, that allows the external motor not to be installed. The ideal solution to apply in cases where there are building and town planning regulations that prohibit it, and for those buildings whose façades are subject to protection by the cultural heritage superintendency. In this case, in fact, the holes drilled in the perimeter wall, covered by grilles with minimal visual impact, have an irrelevant impact on the state of the place.

Installation

Installing air conditioners without an external unit is certainly an easier task than installing classic air conditioners.

First, the two holes that will connect the split with the outside must be drilled, taking care not to puncture electrical cables or water or gas pipes. Obviously, you need a wall that communicates with the outside, so that the air does not have to cross too long a path.  

We recommend to use a core drill to drill the holes in the wall in a clean and unobtrusive manner. At this point the two pipes of the system should be installed, providing a plastic container where the condensate will fall, and which should be emptied periodically. The next step is to connect the air conditioner to the mains supply and to the wall mounting bracket.

Advantages

The most important one is certainly the absence of an outdoor motor. A lack that brings with it other advantages, such as aesthetics and external noise.

As explained above, this is a solution to be adopted especially where there are constraints that prevent the installation of an external unit. Lastly, the simplicity of installing an air conditioner without an outdoor unit, compared to classic units, should not be underestimated.
