When it comes to air conditioning rooms with special microclimate conditions, they often turn to a separate type of air conditioners - precision air conditioners.
They are used in air conditioning systems of server rooms, laboratories. Accuracy, quality and reliability are the characteristics that a precision air conditioner is associated with.
What is a precision air conditioner?
So what is a stationary precision air conditioner? Externally, this device looks like an ordinary cabinet or box, and consists of one working unit. In some models, a condenser can be added to it, but most often manufacturers try to hide this element inside the device.
Recently, many designers of climate control equipment have switched to a standard system consisting of two blocks. In one of them, the main elements of the cooling system are located: a compressor, a fan and a separate automatic control module. And in the second, a condenser and a fan are installed that cools it.
There are three types of precision air conditioners:
1. Cooling. They have limited air conditioning functionality, designed exclusively to lower the room temperature.
2. Cooling with an additional humidifier. An additional humidifier, provided in the design of the device, makes the air more pleasant and refreshing.
3. Combined devices, including both the function of cooling by temperature and heating.

How a precision air conditioner works
The refrigerant, compressed in the compressor, increases its temperature and is fed to the condenser in gaseous form. There, the freon gives off its heat and condenses, turning into a liquid state. Then the liquid refrigerant, passing through the throttle valve, lowers its temperature and pressure.
After that, it is fed to the evaporator, where the cycle begins again. The air that is blown through the evaporator is the one from which excess heat must be removed to maintain the specified parameters in the room. The air, passing through the evaporator, gives off its heat and is fed back into the room.
Air conditioner installation locations
Before installing a precision air conditioner, it is necessary to determine the location of its installation. The installation of a precision air conditioner depends on its purpose. Most often, it is placed on the floor or support frame. In this case, the following factor is taken into account:
Warm and cold air flows should never intersect.
For this, corridors are created for cold and hot air. Naturally, the choice of placement is influenced by the location of the heat source and the layout of the room, as well as the customer's wishes, which are also taken into account. Some of the important indicators when choosing an installation location are the permissible length of the freon line and the height difference between the indoor and outdoor units.
If desired, you can create a false structure through which air will be supplied (false ceiling, false floor, etc.). A false floor is less common, but for precision air conditioners with lower air supply, it is indispensable when it is necessary to supply air evenly throughout the room, and not to a specific object.
Thus, the false floor hides all communications without harming the interior of the room, and only the grilles give it away.
