Precision air conditioning: what is it? Principle of operation and scheme - Setafi

If you thought earlier that the air conditioner cools the air only for your pleasure and comfort, then you are deeply mistaken. There is one device without which server centers simply burn from the heat, and computers melt when it is not installed. Of course, we are talking about precision air conditioning. In this article, we will take a closer look at the structure and functions of the device.

Precision air conditioning - what is it

Let's talk here and now. This is a device that helps to maintain several parameters in the room at once: air temperature, humidity percentage and air mass circulation activity.

A precision air conditioner is a detuning:

• range of variability of temperature indicators within 0.5-1 degrees Celsius;

• humidity variability up to 5%;
• work with the environment in the range from +50 to -60 Celsius.

At the same time, precision air conditioners have incredible accuracy and can easily withstand loads that are not subject to traditional split systems.

The device is installed where even a couple of minutes without a temperature regime can become a disaster and enormous material losses.

The main point, without which a precision air conditioner circuit is impossible, is the availability of backup power. If it turns out that the main power is turned off, then alternative power is automatically connected (battery packs or entire autonomous generators).

Which industries use air conditioning systems?

The use of uninterrupted cooling or heating of air in such areas as:

• telephony stations - automatic telephone exchanges or their hardware;
• mobile communication nodes;
• remote stations based in container boxes;
• billing centers;
• data centers of IT companies, computer rooms.

In rooms where expensive industrial equipment is located, pharmacists also use the principle of operation of a precision air conditioner. So are biologists in laboratories. There, new breeds of plants are bred or unique varieties are crossed.

High-precision production (cosmetics, medicines) by no means can do without a reliable air conditioner.

You won’t believe it, but that’s not all - even in museums and institutes where especially valuable and ancient exhibits are stored, precision equipment is used, but already of a more budgetary plan than in the first presented industries. There is no need for precise technique here.

Precision air conditioner: principle of operation, scheme

The complexity of the apparatus points to its many-sided internal structure. Mandatory elements of the system:

• indoor unit (looks like a whole closet);
• outdoor block.

In the first, the air is transferred to the system for its further processing and supply back to the room. The second contains an air cooler or condenser. The first is set when the circuit operates on liquid condensation.

In addition to the above designs, here are the main details that an air conditioner should have:

1. water pump;
2. evaporator;
3. throttle;
4. filtration systems;
5. electric heaters;
6. humidifiers;
7. air coolers;
8. control and stop valves.

The rest is a variable component of each model, which will differ in functionality and range of previously considered indicators.

Precision air conditioning - how this device works

The main points, so as not to go into the structure of each detail, are as follows: first, the gaseous component is compressed in the cooling element. Then it enters the condenser. There, the air, under the influence of the refrigerant, gets rid of its heat and is transferred to other systems.

The next stage is the passage through a special throttle. The result of the procedure is a noticeable decrease in the temperature and pressure of the coolant.

In this state, the entire "mixture" is transferred to the evaporator. The mass again turns into a gaseous state and returns to the condenser, and the already evaporated air enters the room and changes the state of its temperature, humidity and other moments.

What is a precision air conditioner through its varieties

Since the design of all devices in this area may differ, it is customary to consider three main types of precision air conditioning:

• ceiling;
• closet;
• inter-row.

According to the method of cooling the air mass, it is customary to distinguish between liquid and gaseous ones, taking the determined coolant as the basis for classification - it can be water or ethylene glycol.

Each of the options has its own distinctive features. For example, liquid is used as a system for bringing air indicators to the ideal; and a cabinet air conditioner - for large areas such as telecommunications or cellular communications.

Each of the described devices must have a backup power system, otherwise the functionality of the equipment is simply reduced to nothing. Therefore, whenever the main power supply is interrupted, it is necessary to provide sufficient power from other sources.
