Design of air conditioning systems

The main function of air conditioning is to maintain climatic conditions for human comfort: heating the air in cold and transitional seasons and cooling it in warm seasons. In some industries, a stable temperature is especially important for the preservation of raw materials.

Answers to frequently asked questions

What is an air conditioning project for?

In order for the system to work properly and for a long time in the future, not only competent installation is necessary, but also a project. It, in turn, allows you to calculate in advance the power of the necessary equipment, select the type and design of the air conditioner based on the characteristics of the interior and choose the installation location at which you can achieve the best performance.

We have been developing and implementing turnkey solutions in the field of engineering systems since 2004.

We specialize in turnkey solutions. From concept to commissioning.

We offer each client not equipment, but a competent technical solution that is optimal for the client.

Many facilities in all parts of the country. We work all over Ukraine.

Design stages

1. Before starting the design

Prior to the start of the design, the Customer provides architectural plans (and/or a design project) with dimensions and heights, data on the number of people and equipment.

2. At the design stage

At the design stage, the first step is to calculate the heat gain of the room, namely, from people, the sun, lighting, and equipment. The required temperature and humidity parameters are taken into account, depending on the purpose of the facility, the constant presence of people, and the type of equipment used. After that, the type of air conditioner is selected.

3. Selecting the type of air conditioning system

Air conditioners are divided into three categories: household, semi-industrial, and industrial.

Household air conditioners are mainly represented by split systems (one indoor unit is connected to one outdoor unit) of wall and floor-ceiling type, with a capacity of up to 5-6 kW.
The line of semi-industrial air conditioners includes a more efficient split or multi-split system, where several indoor units are connected to one outdoor unit. A wider selection of units is offered in terms of appearance: in addition to wall-mounted and floor-ceiling units, cassette, ducted and column type. The power range varies from 5 kW to 25 kW.
The industrial segment consists of more serious capacities. This includes VRF systems, when up to 60 or more indoor units are connected to one unit; compressor-condenser units that work only for cold; chillers; and central air conditioners combined with ventilation.

Household and semi-industrial air conditioners are more commonly used in residential premises (apartments, private houses) and small commercial facilities (shops, etc.). Industrial air conditioners are designed to maintain the microclimate of commercial, government and industrial buildings.

In turn, air conditioners are divided into the following types:

Wall-mounted. The units are mounted on the wall, have the widest range of designs, and are easy to install. The disadvantages are noise and direct airflow, which is why you should not install the unit directly above the workplace. They are controlled by a remote control.
Floor and ceiling mounted. They are installed both on the floor and on the ceiling. Of all the units, they are the least used.
Cassette. The units are mounted in the ceiling and are designed for higher rooms (4 m and above), covering a larger area than wall and floor-ceiling units.
Ducted. The quietest of all units, but also the most difficult to install and expensive, requiring additional components (air ducts, diffusers, etc.). The only one of all types designed for flush mounting (optional), which is both a plus and a minus, because there is not always a place to install it.

After the final choice of the type of system is made, the installation location of the units is agreed upon based on the interior of the room. Air conditioners are most often placed closer to the source of heat, for example, near a window. It is imperative to take into account where people will be located. A direct stream of cold air should not be allowed to constantly hit a person. This can affect health and well-being.

4. Coordination of drawings with the customer, designers and builders

When the arrangement of the equipment has been determined, the development of layouts begins, where, in addition to air conditioners, routes and the placement of remote controls are indicated. With more complex systems (VRF systems, chiller-fan coil), a three-dimensional selection scheme is added to the project.

Tasks are prepared for electricians with the characteristics of the equipment for the correct calculation of power cables. A task for plumbers is added, indicating drainage connections for condensate drainage from the units.

The drawings are agreed with the Customer, designer and builders whose communications may be affected by the air conditioning system. The mounting of outdoor units is agreed with the builders.

5. Preparation of equipment and material specifications

At the final stage, the specification of equipment and materials is drawn up and the final amount is calculated.

As a result, the Client receives the following documents:

descriptive part (note)
table with equipment characteristics (electricity, electrical parameters, dimensions, etc.)
plans with the placement of indoor and outdoor units
plans with pipeline placement
plans with the placement of consoles
three-dimensional diagram with selection
tasks for electricians
tasks for plumbers
equipment specification
certificates for equipment

Cost of the air conditioning system project

The cost of an air conditioning system project depends on the size of the premises and the type of system chosen, which also affects the development time and complexity of the project itself. There is a big difference between installing a few split systems and a complex VRF system with a dozen installed indoor units. In the latter case, installation without a project is simply impossible. And without proper selection of routes, the system will not work.

Answers to frequently asked questions

To develop an air conditioning project, you need architectural drawings or a design project with dimensions and areas, a specification of the premises (which indicates the purpose of the premises, for commercial and industrial facilities – the fire safety category), and the arrangement of furniture and equipment.

You also need to indicate the number of people in the room; the parameters of technical or laboratory equipment, if any; what are the restrictions on ceiling heights, how much ceiling space we can take away, or even if the ventilation is planned to be open.

You need to specify a place to install the equipment with access for maintenance. You can also add your wishes for the equipment (imported or domestic, cheaper or more expensive, or a certain brand).

The air conditioning project includes:

floor plans with the following systems: equipment, pipelines, air ducts, grilles, along with references, dimensions and air flow, lowering of ceilings, markings and designations
hydraulic calculation of the system and selection of equipment
cuts for non-standard assemblies
axonometric diagrams for spatial representation, with all notations, positions and footnotes
equipment selection table with its characteristics and capacities
tasks for electricians with points of equipment connection and indication of the required characteristics
tasks for plumbers with connection points and parameters
tasks for builders indicating the size of openings and their references
tasks for the installation of mounting frames and fasteners for equipment, indicating weight, dimensions and references
specification of equipment and materials
explanatory note

It depends on the area and type of object. If it is an apartment project, then it takes 1-2 days to develop a conceptual solution, a couple of days to coordinate with the Customer and the designer, and after confirmation up to 5 days to fully complete the project. If the object is commercial or industrial, with an area of more than 1000 m², the development of the project may take 1 month or more. There are also many factors that depend on related organizations.
