Ventilation is the process of removing contaminated air from rooms and replacing it with a fresher and cleaner one. Its main task is to create optimal and comfortable conditions for a person that meet all sanitary requirements. For this purpose, in each industrial building, as well as in residential buildings, special ventilation systems are installed . Regular maintenance and proper operation not only contribute to the safety of equipment and money, because they prevent ventilation repairs, but also prevent discomfort and health risks.
How to detect a system crash?
To make sure that the air environment in the room is maintained at the proper level, there are many ways:
- Carefully review all ventilation openings. Make sure that they are free of mold.
- There must not be a musty smell in the space, otherwise it is necessary to repair the ventilation.
- Pay attention to the complaints of residents of the house or workers in an industrial building.
In addition to this, it can be noted that scheduled maintenance not only guarantees the preservation of air quality, but also helps to reduce the cost of utility bills and the purchase of new climate equipment.
Proper ventilation: repair, maintenance
All work on the repair and maintenance of ventilation systems is carried out only by a qualified specialist. Do not trust casual professionals, as this can lead to negative consequences.
The main steps to establish the operability of equipment:
- Regular replacement of filters (every 1-6 months) will help free up space from dust and harmful microbes.
- Cleaning the evaporator and coil condenser (1-2 times per year). It is in these places that mold often accumulates due to direct contact with the outside air. Special antifungal agents are an excellent solution to this problem.
- Lubrication of shock absorbers (every year). This is the most common malfunction in climatic equipment. If it is not eliminated, repair of ventilation will require large financial costs.
- Inspection of fans, bearings and belts (2 times a year). Timely detection of problems can save the system engine. Replacing it is a very expensive procedure. Belts should be aligned and not too tight to prevent wear. Untimely lubricated ball bearings will lead to the formation of noise and vibration, and their failure will cause a repair of the supply ventilation.
- Checking the area around the air intake (twice a year). If water accumulates in this area, mold will certainly appear. This means that spores can enter the ventilation system, and then get into the room.
- Search for air leaks (annually) and, if necessary, replace latches, gaskets and screws.
- Cleaning the air ducts (every 2 years) from dirt and dust.
Software operation
Ventilation control systems are presented in the form of special thermostats, with which you can track the heating and cooling processes throughout the building, as well as temperature and humidity control sensors in the rooms. These devices must be constantly checked to prevent a program malfunction (for example, when the room is hot, the heating mode is turned on) and ventilation repair.
Charts
Routing channels and control circuits must be attached to the technical documentation of ventilation devices. Since they will not only easily tell you how to troubleshoot the system, but also help in its modernization.
It is important that all components of the air treatment and the boundaries between the various control zones are precisely marked on them for easy reading of the schemes.
The new generation of HVAC equipment
High energy costs and global environmental problems compel modern scientists to carry out the fundamental research necessary for the production of ventilation devices and components of a new level. Here is a short list of tasks that professionals are currently working on:
- Creating pipes for smaller heat exchangers. This will make it possible to provide more efficient heat transfer, as well as reduce the risk of money costs for the repair of ventilation systems.
- Use of other materials for heat exchangers. It is proved that carbon and graphite foams, plastic and polymer, ceramics significantly increase heat transfer.
- Found new ways to drain the air without cooling it.
Thus, we can conclude: the chain “ventilation - repair - maintenance” directly depends on the proper operation and professional technical inspection of all system components. Timely detection of malfunctions will prevent its malfunction and, most importantly, reduce the risk of threats to human health.
