Literally every building has its own characteristics and needs an individual approach. Our initiative and search for the most effective solution will guarantee for you the optimal performance of the created system.
The formation of the internal environment of the building is influenced by numerous factors, including location, building materials and applications. The structure is in continuous interaction with the environment, because the change in temperature and weather significantly affects its internal climate.
If we consider the case of power plants, it is necessary to take into account such factors as: excessive heat and humidity of air, removal of combustion products that are formed during the procedure of energy production, and in the conditions of stations specializing in processing biomass, this is also an unpleasant smell.
Our professional integrated approach necessarily takes into account the above factors that affect the environment established within these buildings and solves the problems associated with proper ventilation of power plants, such as, for example:
- Too high temperature (any station, as a rule, has a minimum and maximum permissible temperature, which is suitable for optimal operation), which worsens the well-being and work capacity of the personnel;
- Poor air quality in the internal station premises;
- Accumulation of excessive moisture condensate;
- The need to ventilate the premises, regardless of the weather;
- Due to pressure, ventilation efficiency can vary;
- There is always a risk of explosion;
- Due to the operation of the equipment, the noise level is high;
- In the vicinity there is an unpleasant smell (near stations specializing in processing biomass);
- Requires attention to fire safety.
In case the building allows this, we will offer, first of all, to develop a system of natural ventilation “Colt”, which can reduce operating costs due to zero electricity consumption.
Among the benefits of such a system, we note:
- Electricity consumption is reduced to zero;
- The maintenance costs of the system are minimal;
- There is no СО2 emission;
- The system functions silently;
- It is capable of self-regulation (the larger the volume of hot air is created, the stronger and faster it rises);
- Operating costs will be extremely low;
- The service life of such a system is very long;
- The probability of failure is negligible.
In order to achieve the most optimal and effective solution it is necessary to concretize the idea of the necessary form of ventilation from the very beginning. In particular, where the conditions for this are available, it is reasonable to use some of the heat that is removed, for example, for heating the air coming from outside. In situations where the type of building or customer’s requirements do not allow us to take advantage of natural ventilation, we can organize mechanical ventilation, which will help achieve the desired result.
Features of modeling situations in order to obtain the most optimal solution
The equipment used by Colt uses a CFD simulation program (ComputationalFluidDynamics) to simulate the conditions under which hot air movement will be carried out in the structure. Such a software tool makes it possible to “predict” how energy will move and transmit within a building under a variety of conditions. Data can be entered in the CFD from the thermal imaging device, and then, based on the sources of heat sources installed inside the building, specialists can simulate the movement of hot air. After completion of the study, they will be able to offer a solution that helps eliminate heat accumulation in the building.
Conducting CFD analysis can be useful for obtaining the most effective combination of smoke removal and heat removal in order to achieve optimal working conditions inside the structure – a comfortable, safe and energy-efficient internal environment.

Formulation of the problem
Our main goal is to make the modern world an ideal place for work and a comfortable life, to help make healthier, safer, more convenient and productive work that fills the surrounding buildings.
The use of natural ventilation in heavy industry
In facilities such as power plants, aluminum smelters, garbage incinerators, and so on, turbine furnaces, piping systems and auxiliary devices give off a huge amount of heat due to convection and radiation. For a comfortable stay in these zones of people, the temperature regime should not exceed the established maximum values. It is obvious that in the factories of such a plan the arrangement of natural ventilation is often an extremely effective ventilation form, and, moreover, the most economically advantageous method. With the increase in the volume of heated air, it is removed by natural ventilation through the roof.
The goal of effective operation of the created ventilation is to maintain a balance between the exhaust and supply air. To achieve this, qualitative development of the system allows.
Criteria for the development of a ventilation system
Determine the ratio of pressure in the building can be by means of a special computer program for the development of natural ventilation. It is on the basis of the received data that the dimensions of the necessary vent hole are calculated, and in addition, the places where it is best placed. It is also necessary to take into account an important point, such as a neutral line in the structure. It means a line over which air has a positive pressure in comparison with environmental conditions. Below this line, air masses have a negative pressure. Due to this, the air will be discharged through the specialized holes, which are located above the neutral line. If these holes are located below the notorious line, then the air will flow through them.
Also, various external factors are included in the calculation, for example, the load exerted by the wind, its direction and location of the structure relative to other buildings. The results of the above calculations become the basis for developing an efficient and reliable, regulated natural ventilation system.
Advantages of installing natural ventilation
The installation of a natural ventilation system involves a number of special advantages, such as:
- In fact, it does not consume energy;
- Does not need maintenance;
- It functions silently;
- Can boast of low operating costs;
- Has a long service life;
- Not prone to breakdowns;
- Requires a small amount of construction work.
In the event that the building or other circumstances do not allow the installation of a natural ventilation system, Colt is able to offer the development of a combined or fully mechanical ventilation system and, in addition, air conditioning systems.
“Labyrinth”: ventilation system installed on the roof
“Labyrinth” is a block for arrangement of natural ventilation, created for the equipment of continuously operating, water-proof ventilation. Such a system is well suited for applications in industries characterized by the allocation of large thermal volumes and noise. In such industrial buildings, on the one hand, it is required to ensure optimal heat removal, and, on the other hand, to reduce the noise threshold. The system offered to you can be used both for removing warm air, and for inflow of fresh air, and also, if there is a desire of the customer, to equip with the function of sound absorption.
“Labyrinth MK2”: it includes lamellas with a standard ventilation capacity, as well as sound absorption.
“Labyrinth MK4”: designed for maximum airflow.
Features of the frame
The frame of the system includes a rectangular formwork, equipped with a built-in lamellar system. These lamellas are put so that the so-called. “Channels-labyrinths”, allowing to reflect sound and reduce sound emission. All models are equipped with edges that hold water in case of rain, then diverted to the roof by a pair of gutters. Due to this design, the system shows an enviable watertightness in the open. Its body is made of high-quality aluminum “Colterra”. Length, height and width can be different, based on individual needs.
If necessary, “Labyrinth” can be equipped with a gate that prevents waste of energy, and also used to control air capacity. The design of the valve includes a frame with static lamellar flaps, used to close the ventilations by moving along the guides. The valve is mounted on top of the frame, it can be controlled both electrically and pneumatically.
