In order to maintain comfortable conditions in a house, it is important to foresee all aspects, starting from engineering systems to the location of furniture and equipment.
An internal engineering system that is responsible for maintaining optimal air parameters indoors (these include temperature, relative humidity and air velocity) is air conditioning..
The first step in a process of implementation of this engineering system is to discuss a concept.. At first – a type of air conditioning system (wall-mounted, channel/duct, underfloor and floor system). If the choice falls on the channel-type system, then there should be decided the placement of the air duct routing and the type of distribution gears (slot diffusers or grilles). In addition, we discuss a location of distribution devices, which fill rooms with cold air and control microclimate in a house.
For additional selection of equipment, it is necessary to obtain the technical design specifications (purpose of premises, wall thickness, technical characteristics of double-glazed windows, etc.) from the client. After this, we start the next stage – the development of a commercial offer.
The next step is designing. After we fully agreed all the details of the project with our client, made changes, we move to the re-approval and signing. After that we can provide our customer with the final offer.
The final stage is installation of the engineering system and commissioning.
There are the following types of air conditioning systems:
Wall-mounted and channel types are the most popular when it comes to implementation of air conditioning in a house.
This type of air conditioning system is the classic one and most common in a domestic segment. Wall-mounted air conditioning system at home or other type of premises is divided into two types:
Split system is a combination of one outdoor and one indoor unit of air conditioner. Such system is perfect for apartments or houses with low ceilings.
Multi split system is designed in such way that the outdoor unit can adjust up to 5 indoor units. The principle of operation and components of the units are identical to the split-air conditioning system.
Wall-mounted air conditioning system has the following advantages:
The implementation of this engineering system is possible with channel air conditioners. In this case, it is important to take into account the lowering of the ceiling by air ducts – 17 cm. To this number we also add drywall and a profile (5 cm), as a result the final lowering of the ceiling is 23 cm.
If the ceiling space in a house allows the installation of a channel-type air conditioning system, it is better to choose this option over the first one. This is due to the quiet operation, high efficiency in terms of air distribution, since the diffusers are installed at far points above the windows, creating a cold curtain, thus, the heat does not enter the room.
The internal units of the channel type air conditioning system can be:
The units are mounted in technical premises in “dirty areas” (bathrooms, toilets, closets, storage rooms, etc.). Mostly, in places where there is a possibility to lower the ceiling. For maintenance of equipment, it is necessary to install an access panel through which all service work will be carried out.
In order to avoid condensate formation and moderate a sound level, all ducts are covered with insulating material. Insulation for ducts can be:
In order to adjust a speed and amount of air in different parts of the diffuser, each connection is equipped with a throttle valve.
Control of the air conditioning system at home is organized by zones, as far as each channel air conditioner operates exclusively for one zone. Since it is not recommended to install a single channel air conditioner for the whole house. This advice is connected with a big lowering of the ceiling, increased noise characteristics and inability to control different temperature parameters in different zones without additional equipment (VAV-system or additional heating elements).
Before starting a designing process of any engineering system, it is necessary to contact the architects and obtain initial data, since in the case of a finished design project, it will be quite difficult to design this engineering system, as far as you may need some significant changes.
There is such notion as an exploitation of the day time period and the night period. So, accordingly, all indoor units cannot function simultaneously and overload the outdoor unit. As a result, the outdoor unit produces as much energy as necessary, and the internal ones evenly distribute this energy among themselves.
Currently, modern houses are energy-efficient and are built using high-quality insulation and double-glazed windows, respectively, the throughput of heat is reduced. Before designing the air conditioning system, a prerequisite is to check double-glazed windows and shading from curtains during the summer time period. This is due to the fact that the more open the glass is and the lower its quality, the more heat enters the room, the greater the load on the air conditioner and, consequently, the greater the energy consumption. Therefore, it is always necessary to pay attention to the windows and shading.
Example of glazing data definition
Air conditioning system in a house is designed to create comfortable temperature in a building. There are such types of conditioning: wall-mounted, channel/duct, underfloor and floor-mounted. When it comes to implementation of air conditioning for a private house, we recommend to install a channel/duct type system, since the height of ceilings in a house is higher than in an apartment. In addition, such type is considered to be much more productive and noiseless.
It is important to mention, that indoor units are installed separately for each chosen zone in order to get more convenient control and efficient work. A channel-type air conditioning system can only be installed if there is enough space to drop the ceilings.
For an apartment, the most suitable option is a wall-mounted air conditioning system. As far as for the installation of indoor units there is no need to drop the ceilings. Internal units of split and multi-split systems can be made in both standard and designer versions.
