Experts in the field of mechanics know well that insufficiently just to place the car in storage to the enclosed space. The last has to have correctly equipped vent system thanks to which the external covering and internal components of the car will remain in proper condition for all year.
Main role and problems of garage ventilation
Carrying out vent system as in garage, so in any other room is necessary for creation in it effective air exchange. Due to the correct arrangement of ventilation in garage in it condensate, exhaust gases and various toxic evaporations which are allocated in use the car will not collect.
Thus, mounting of garage ventilation has to be directed to the solution of the following tasks:
- prevention of the increased humidity which is formed at hit to the room of rain, snow and also dirt from the car;
- elimination of gas evaporations, harmful to person;
- protection of walls and ceiling of the room against mold and the other fungal formations arising because of congestion in condensate garage;
- the careful maintenance of the car, tools and other accessories in dryness and protection them from corrosion and rust;
- creation of favorable microclimate in garage cellar (at its availability) for long-term storage of vegetables and other products.
Types of garage vent systems
The most widespread system is natural ventilation. It differs in simple realization and does not demand the big budget therefore most of motorists inclines to the choice it. The scheme of the device of natural ventilation provides receipt and removal of air flows through the incoming and exhaust openings. Availability of its realization is complemented with fast and simple calculations.
The system of mechanical ventilation becomes more effective, but rather complex in realization. Its separate advantage consists in lack of need to make calculation of the area of garage as continuous air exchange is provided with the integral fans. They are responsible for receipt and extract of air in the volume, necessary for garage and cellar. For the rest the owner of garage is expected by difficulties with realization of similar system: the equipment for it costs much, and without special knowledge in construction and power of work become almost impracticable.
Rather known way of aeration of garage – combined. It combines natural intake of air and with conclusion fulfilled by means of compulsory by vent system on the basis of the fan installed in air duct. The device of such system becomes difficult because of long calculations without which it is impossible to combine the systems of aeration of air, various on the features.
Thus, creation of natural ventilation according to the following scheme where 1 — the direction of air will be suitable for midsize garage; 2 — air vents; 3 — ventilating box:
Calculation of parameters of garage ventilation
As key parameter of air exchange its frequency rate, that is quantity of full cycles of change of air in garage for hour acts. As a rule, this value (n) is 6-10 m3/h. Also important parameter for further calculations is the internal volume of garage (Vg) which is calculated by means of multiplication of its internal dimensions - lengths, width and heights.
Having received the necessary parameters, it is necessary to calculate consumption of indoor air for hour by formula: L=n*Vg. In other words, the received size will show the air volume contained by garage. Knowing it, it is possible to pick up correctly the section of air ducts of extract and pritochka for what the received value L is rounded towards increase (it has to be multiple 5). For simplification of calculations it is possible to pick up suitable value, being guided by the following table:
As a rule, the air renewal rate in natural ventilation of midsize garage makes about 0.5-1 m/s therefore round air ducts which dimeter has to make from 500 mm will become the optimum choice. It is possible to stop on the pro-thinned-out components, with internal section from 450 by 500 mm. To normalize air inflow, the design can be added further with the trellised air intake, having established it at the height up to 0.5 m from garage floor.
Order of arrangement of ventilation of garage the hands
Before works it is necessary to prepare the following tools and materials:
- the Bulgarian (for cutting of pipes);
- sealant;
- the perforator (for creation of openings);
- plastic pipes;
- caps and protective screens.
Further it is possible to start mounting, following the step-by-step management:
- At first it is necessary to make air vents in walls, having calculated their diameter. If to be guided by norms, for average garage (6 by 3 meters) diameter of openings has to be not less than 27 cm. They are made by means of the perforator at distance of 10-15 cm from floor. In the received openings air ducts from pipes are mounted.
- On opposite wall (is 10 cm lower than ceiling) openings for installation of vent pipe which will go beyond garage roof are carried out. The it is higher, the air exchange will be more effective. Minimum height of design over roof has to be 50 cm.
- After installation of pipes in apertures it is necessary to close up sealant gaps between them and wall. Exhaust outlets of pipes are closed by the grids protecting from penetration into the room of small rodents. For prevention of hit of precipitation in pipe the protective cap is established.
Ways of improvement of work of natural extract of garage
At the organization of natural ventilation by the hands it is possible to achieve optimum updating of the atmosphere in garage without mechanical tools, for example, by heating of exhaust pipe and installation of the deflector. The warmed-up air easier cold, and, rising up, it will quicker come out through aspiration duct, being replaced with fresh external air.
For improvement of warming up of air in not heated garage it is enough to paint aspiration duct with black paint. So walls of air duct will absorb more solar energy, heating air in the channel and pushing out it up. When planning natural ventilation with further painting of air duct the need for additional thermal insulation of ventkanal vanishes therefore so simple and available measures will also help to reduce costs on purchase and mounting of the main components of system.
The cold weather coming since fall in itself they do not create particular problems for the car which is stored, however ways to seriously break operation of all forced-air and exhaust ventilation system. The hot engine will give additional heat within hour after arrival of the car to garage, but further in not heated garage temperature will go down practically to street values because of what natural ventilation will cease to work.
For air exchange preservation indoors and prevention of frosting of aspiration duct in which condensate will inevitably collect it is enough to buy the normal 40-watt glow lamp. It should be established under aperture of vertical aspiration duct and to leave included. The lamp will generate heat, providing the movement of air at speed up to 0.4 m/s. In addition the channel of air duct needs to be covered with thermal insulation material, having made sure that moisture does not come to it. Increase in level of fire danger indoors in this connection it is necessary to buy the most reliable and safe glow lamps becomes lack of similar way of improvement of heat exchange.
