Conditioning – is a climate system designed for maintenance of comfortable temperature in the room, which is easy to implement with professional equipment.

Talking about the air conditioning in the offices, clean and cooled air is a necessity for the working area, since in the summer period the air outside is warm and polluted, has many unpleasant odors and dust, and in winter it is too dry, which significantly reduces the workers’ productivity and increases the risk of developing various diseases. Cooling offices can also have a beneficial effect on the comfort, productivity and well-being of the staff, which is important both for health and work in general.

A properly designed and adjusted air conditioning system is able to provide certain temperature conditions in the room to maintain the most comfortable microclimate.



Air conditioning is, first and foremost, the right temperature to ensure human comfort. When creating an air conditioning system in office premises, most often engineering specialists use split systems (up to 5 rooms) or multi-zone systems (5 or more rooms).

The air conditioning system can be organized using two types of cooling:

  • Freon type,  which means that the cold is transferred from the outdoor unit to the indoor unit through freon lines.
  • Water type, working with the help of a chiller or heat pump, preparing cold water and supplying it to fan coil units.

Further we will consider how it works.

Before starting to choose the equipment, it is necessary to determine the heat input of a specific room in order to understand the power and the amount of heat that needs to be compensated by a split-, multi-split system, VRV, chiller, heat pump, etc.Without calculating heat input, the probability of choosing the correct power is low. Therefore, it is the first step in the design of an office air conditioning system. Many factors are considered, including, but not limited to the area of the room, the number of employees, internal and external heat supply, cardinal directions, number of storeys, solar factor for double-glazed windows and the presence of shading constructions (blinds, awnings, etc.).

If the office is located within the city, the air heat pumps are used, rather than the geothermal ones, since the usage of the latter presupposes the presence of a well, which is almost impossible to do. Alternatively, a chiller can be used, its operation is based on cooling the premises with water through fan coil units. Fan coil units can be of wall, floor or duct type – depending on the capabilities and requirements of the room. In case of fan coil units, you need to remember about the correct selection of their standard size – the smaller the size at high power, the more noisy it works. Therefore, it is worth making a choice in favor of quiet operation rather than a smaller size.

Today, VRV systems or chillers are most often used for air conditioning large offices. To implement these systems, it is necessary to make the correct preliminary calculations, since there are always people in the office who need the correct temperature and a certain amount of air.

One of the most common sources of cold generation in an office is internal cassette units and the next ones are wall and duct units. Cassette units are popular due to their reasonable price and the ability to distribute air flows in several directions (2 or 4 flows). Wall-mounted air conditioner units are also often found in offices, however, if there are more than 2 workers in one room, the probability of comfortable refrigeration distribution is close to zero, since the air flow from the unit will certainly touch some of the employees. Ducted units are considered one of the most expensive, since they require piping with air ducts, aerodynamics, diffusers, grates, etc., but for the comfort of air distribution they are the best, especially in combination with high-quality diffusers.


    To maintain comfortable conditions in the house, it is important to provide for all aspects, from engineering systems to the arrangement of furniture and equipment.

  • Air conditioning
    for apartments

    Air conditioning in an apartment is the process of maintaining a comfortable indoor microclimate in terms of temperature. A favorable atmosphere in the apartment, consisting of a convenient temperature schedule, optimal air velocity and the required humidity.

  • Air conditioning

    We all know about such an indicator as air humidity, but not everyone knows about the impact of this indicator on the health and comfort of a person. The system of air humidification is designed to deal with all air problems. It can be arranged with the help of equipment of different classes and budget. These can be ordinary household air humidifiers (from which, frankly speaking, is not worth waiting much of an effect), or it can be a humidifier, which is integrated into the system of ventilation and thus solve the problem in a comprehensive manner.


Equipment placement

In office conditioning it is necessary to consider the location of outdoor units, if possible, they should be installed on the north side, for maximum heat transfer from the heat exchanger. Thus, it will cool down faster and not be exposed to sunlight.

It is not recommended to expose external blocks of split or multi-split systems to direct sunlight (on the roof), as their performance may be impaired.

What you need to know when organizing a conditioning project

An office conditioning system is based on an integrated approach, where it is important to consider absolutely all factors that may affect the further operation of the equipment.

  • Indoor heat emitted by equipment/people (computers, average number of people, lighting, etc.)
  • Thermal resistance of walls/roof.
  • Number of double-glazed windows, solar factor, their placement (which side the sun comes out on).
  • Ventilation system (or estimated window opening times).
  • Room area/ceiling height.
  • The presence of shading structures.

Price or long-term reliability?

Since the conditioning system is equipment that is designed for a long operating period, it is worthwhile to carefully approach the selection of equipment. For example, Chinese manufacturers have a large flow of products and may stop production of a particular model in a few years. Accordingly, over time, with the slightest breakdown or failure of a certain part, replacement can cause a lot of inconvenience. At the same time, European brands focus more on the buyer, assuring that parts for the equipment sold will be on the market for about 20 years.

Of course, the reliability of the components also differs significantly. The selection of equipment must be carried out considering the budget, requirements and whether the premises are rented or your own.

How often and why to carry out the service of the systems

Service maintenance of the conditioning system is an integral part of the correct and adjusted operation of the equipment. This is especially true for premises such as offices, where the traffic of people is large, nearby there are roads, factories, construction sites, etc. Maintenance of the conditioning system consists of replacing filters that protect the heat exchanger, retaining all dirt and dust from external contamination, and also prevent the appearance of mildew, mold or equipment breakdown. It is necessary to contact the service strictly following the schedule or the recommendations of the engineers, since the office can be located either in a relatively clean area or in a more polluted one, where filters will have to be replaced more often. It is recommended to carry out the service twice a year – before the beginning of the season (spring) and after its end (autumn).

Which systems we offer and why

The most efficient conditioning system in terms of air exchange and comfort is the low-pressure ducted system. Air supply with this system is as correct and convenient as possible for use. It does not generate noise during operation and is not felt due to the smooth distribution of air flows. It is invisible in the interior, and control and configuration is easily carried out using controllers.

Middle efficiency comfort is provided by a four-way cassette, which is placed in the middle of the room and evenly distributes air throughout the room, and the least comfortable is the wall-mounted type. A common problem with cassette and wall systems is the active flow of air, which passes into the room cool enough, not allowing the human body to feel comfortable. And the duct system supplies air along the hot glass unit, respectively, the air in the room will be much more pleasant.

The most common and reliable type of cooling is the freon circuit. Depending on the technical capabilities of the building, we use: split, multi-split, mini-VRV or VRV systems. Since most often it is preferred to do air conditioning of office premises using the most compact systems, multi-split and VRV systems come out on top in terms of requests and design.
