Air curtains for industrial gates. PVC strip curtains: ribbon curtains. What types of curtains, their design and work features

June 25, 2015. Alexei

The heat curtain on the gate in the shop refers to the industrial type of equipment. But the main function of such equipment is similar to the one that other analogs are implemented - the creation of an air barrier to mix cold air from the street and warm out of the room.

There is pretty big choice Such devices, which allows you to install them on any side of the gate: on the side, above them, at the bottom.

For which they serve and where they can be used

The heat curtain in the production workshop is mounted in order to reduce the loss of heat in the premises, where most of the time the doorways are not protected from the penetration through them the air from the street. This happens when loading / unloading, frequent entry of transport. But in addition to production facilities, such a technique is often established in private - in garages. Another area of \u200b\u200bapplication is civil objects, such as auto repair shop.

We watch the video, the principle of operation:

The thermal air curtain on the gate to the shop allows to significantly save energy, which is due to the lack of the need for intensive warming up of the room after each opening of the gate. However, the effectiveness of such equipment also affects the location.

For example, in the garage or car workshops, where the picture is often observed when the transport stops directly in the opening itself, it is very recommended to use the lower version of the blowing, since the upper supply of warm air simply will not block the flow of the cold air due to the car's opening.

What types of curtains, their design and work features

Electric curtains

There are two types of equipment used today with unidirectional feeding of heated air:

Industrial thermal air curtains For the gate, the shoelable - they provide a calorifer, by means of which the device warms the air environment to a certain temperature value;
Mixing - function based on the principle of outdoor intake.

There are also similar techniques and on the mode of operation: on a constant or periodic basis. There is also a classification in the direction of the served airflow:

Flow movement takes up upwards. In this case, the devices are installed at the goal. As mentioned above, this method is not always effective, but only when machines often stop at the gate. However, there are deficiencies in this solution - this is too fast clogging of the mechanism, which is why maintenance is required.
Aircraft movement from top to bottom. This is a classic way of location like this technique. The equipment is installed directly above the gate.
The directional flow moves in the horizontal plane, which is implemented by the location of the devices on the side of the gate.

Other groups are also distinguished by design:

Thermal air curtains on the Water Gate are functioning on the basis of an active heating system or hot water supply, which makes it possible to mainly warm the air with the direct participation of the coolant;
Electric - Unlike the first option, it can be used almost everywhere if there is a dedicated power source for its connection on the object, while water plants are used where obligatory must be heating system or hot pipeline.

The principle of action of such equipment is similar to all versions: by means of a powerful fan built into the device body, air is injected. Its output can be organized different ways, it all depends on the type of installation. But in any case, the design will provide a gap specifiedThrough which the air is fed to the border of the object and the external environment.

Thermal air curtain for the garage or for the workshop is selected taking into account a number of parameters:

When the diesel or gas is selected heat gun For a garage or a device for the workshop, in both cases it is important to properly determine the thermal power of such equipment, which will improve air at the required height and with sufficient speed.

We watch the video, the criteria of choice:

When choosing an aggregate with necessary power It is necessary to take into account the size of the room, as well as the level of its thermal insulation and the average temperature of the outside and inside the object.

How to calculate thermal power and air flow

To calculate sufficient performance, it is necessary to approximately represent, at what speed in the room there is a certain volume. For this multiplies the value of the speed of the air flow and the volume of the room. The resulting value (L PR) is used to obtain the value of the required aircraft consumption using such equipment:

Lzov \u003d LPR / J (B / B + 1),

where j is the coefficient that determines the strength of the flow created by the device corresponds to the value of 0.45;

B, b-parameters of the gap, through which air flow will be supplied.

Calculation of power thermal curtain on the gate:

Quap \u003d 0,24ls (TZ - TNach),

where t z, t start - the values \u200b\u200bof the averaged temperatures directly the air curtain itself and the outer environment, respectively.

FEATURES OF INSTALLATION AND OPERATION

There is a similar technique as close as possible to the impact. At the same time, the highest degree of efficiency is achieved when organizing a protective jet of air. It is also important to ensure that the length of the device corresponds to the width of the opening, if the installation option was selected above the gate. In the case when the vertical installation is mounted, then it is necessary to select its length, based on the height of the gate.

All work on the installation of such equipment is performed exclusively on the inside of the room. Another an important nuance - Control of the operation of air conditioning and ventilation systems to avoid additional impact on the operation of the device. If the gate is too wide, then you can use several installations. Their compound is implemented in this case by means of a special connecting kit.

We watch video, installation and installation:

Depending on the type of device selected, the mechanism can be equipped with fastening elements: for wall or ceiling mounting. Managing such a technique is also made in accordance with the type of device. When installing the curtain, it is necessary to select an anchor, taking into account not only the main weight of the structure itself, but also takes into account the likely load in the event of vibration waves, which is especially important in repair shops and production workshops.

Thus, the choice and installation special equipment To create air curtains is somewhat more complicated than buying such equipment as a diesel heat gun for the garage. Although before purchasing industrial device Accepted into account thermal power, Air supply speed and performance performance. But these parameters are still added to select the installation method (ceiling, wall, outdoor), assessment of the load on the fastening elements and, of course, the dimensions of the equipment itself, which will create an air curtain over the entire width of the doorway or gate.

IN winter time The year in industrial and warehouses there is a problem of getting wet and cold air masses. This is especially true of the territory at the entrances and doorways. To protect the working personnel and maintaining normal temperatures in industrial premises, industrial heat curtains For gates. They support the optimal microclimate for people and products and do not miss extra moisture.

The principle of operation of thermal curtains

In warehouses with a large gate, unloading of raw materials or goods is often performed. This creates constant temperature and humidity differences. Such processes negatively affect products and raw materials, and especially in the state of health workers.

Another significant lack of temperature drops - increased heating costs. And in the case electric heating And air conditioning is also huge bills for electricity.

The air thermal curtain is hanging on the territory of the loading of goods and protects the room from cold streams. The device works on the principle of thermal gun: air flow under high pressure Served on the area of \u200b\u200bthe gateway. On some devices, the air is served from the street on others it is heated. The angle under which air is supplied, ranges about 35-40 degrees in the range. The convenience of the device is that it does not interfere with the passage of loaders and movement of personnel.

Distinguish such types of curtains:

Estimated - such curtains are equipped with a calorifer, which warms the air masses supplied to a certain temperature. Often they are used where you need to create a specific microclimate.
Mixing - Such devices take air from the street. Such devices for technical premises are used.

Depending on the view of the room, attention is drawn to one of these types of curtains.

Types of industrial curtains

Every heat curtain has its own constructive features. Such devices are divided into several types:

by operating mode;
by type of air mass;
by location.

Different and the mode of operation of various air curtains for industrial gate. For example, warehouse veins can only work at certain periods of time or constantly. In the first case, the device starts working only at the moment when the doors open. Such a solution is fairly economical. However, for stable operation of the thermal veil of periodic action, it is necessary to establish their work.

At the same time, the devices that are in the permanent state are capable of performing an effective heating device. Often, devices are used for exhaust.

Industrial curtains differ in the direction of air:

The stream is spread from the bottom up. In this case, the gap is in the opening below.
The air goes from above-slot placed above the opening.
Horizontal flow - the slot is located on the side. Often such devices are used for high width openings.

Each type of curtain has certain advantages that should be considered when choosing a device. For example, to choose the appropriate type of curtain for wide, but low opening, it is worth paying attention to devices with lower air supply. They make it possible to effectively cope with the propagation of cold air masses on the floor. However, such designs have a substantial minus - they require frequent maintenance, because they are easy to clog.

Curtains with upper air supply are ineffective when stopping in the opening vehicle. They are not able to delay the flow of cold air passing under the car. For these reasons, the lateral location curtains are often mounted on industrial facilities.

The devices located above the opening have another substantial minus - they are ineffective at a high height of the opening. If you classify curtains at the place of the air intake, it is worth splitting them on such types:

with internal fence and heated - such devices take air directly from the room, which is protected from the cold;
without heating;
external heated - Air masses are closed from the street;
the fence is carried out outsidebut air does not heat up.

Some curtains can be used as inlet device Ventilation or additional heating equipment.

Nuances Installation

When calculating the curtain, which will be installed in the warehouse or industrial, should be considered:

the number of openings and the intensity of their operation (open periodically or permanently);
whether vehicles will stop in the openings;
is the openings installed the air conditioning system.

Depending on these indicators, certain air heating norms are established in the opening zone and the temperature indicators of the veil.

Toughness calculation

Before buying a specific thermal curtain model, it is worth calculating the optimal indicators of the system. They are based on the source data. This approach will increase the efficiency of energy consumption.

The main parameters when carrying out calculations are:

the overall performance of the system - depends on the set of factors;
the speed with which the air masses are blowing out with a fan;
angle of inclination of the air flow;
the size of the opening;
califer power;
the power of the coolant.

Special techniques are used to calculate. Each of them guarantees a certain accuracy of the result. Even a small inaccuracy in the calculations may result in significant loss of electricity.

Constructive features

The specific model is selected in accordance with the tasks solved. For example, the lower curtains are purchased for the car gate. In this case, the device is installed at the floor level. The direction with which air will be done can be adjusted by installing special slothes.

If the gate is standing in a room, which often drives cars, it is necessary to look at vertical devices located in the 2 sides of the opening. In this case, it is possible to apply both products with a fan at once on 2 racks and independent devices. Air can be closed from different areas of the room.

The curtain, located horizontally and mounted above the gate, is used when air flow does not exceed 38 thousand cubic meters. m per hour. If the curtain is installed on a high opening, it is better to use hot air (about 60 degrees). This will create an open temperature at thenime.

Often, in order to prevent the penetration of cold air masses, the lower fence is applied.

In addition, special attention is paid to the air duct area, by means of which the influx of fresh air is carried out. It should ensure the uniform of the head of the air masses.

Automation

To more conveniently manage thermal veins, special automation is mounted on them. Such equipment solves several tasks:

running and stopping the fans during the opening and closing of the gate;
continuous change in temperature indicators of air flows taking into account changes temperature mode on the street indoors;
start and stopping the veil when changing the temperature on the street.

When installing automation on the gate, the use of automatic control systems of thermal curtains helps to save on electricity consumption and get a cost-effective engineering system.

The "Thermomir" store offers buyers a wide range of air thermal curtains. Sale of heat saves is carried out on the official website wholesale and retail.

One of the most effective options Protection against the penetration of cold air into the room is a heat curtain. A wide air flow device separates the heated room from cold air from the street, protects against dust and insects, provides a comfortable microclimate in the entrance zone, allows you to save energy for heating, and in the summer saves coolness in air conditioned rooms.
Air curtains are installed on entrance groups Buildings S. large quantity Visitors: in shopping and entertainment centers, metro lobby, cafes and restaurants, large offices, banks, clinics, etc.

Curtains are with heating - electrical and water (on hot water), as well as without heating - air.

Electric thermal curtains They work from the mains, can be both domestic and industrial, have several operating modes with power switching and can work without heating ( summer mode). Curtains with a capacity of up to 5 kW work at a voltage of 220 V network, and from 5 and higher - 380 V. Household curtains are actively used for doors in country houses and dachas.

Water thermal curtains They differ from electric much more power, so actively apply for large objects - doorways and gates of large warehouses, shops, shops, hangars, etc. These curtains have stationary mountingare connected to the main hot water and are characterized high efficiency and air performance.

Air curtains without heating Used where it is necessary to divide the heat zone and cold without additional heating. These devices are not equipped with heating elements, and work as large fans, allowing you to separate from heated premises refrigerated chambers, zones or warehouses with cooled products, prevent smoke and dust to other rooms, for example, in working workshops and workshops, etc.

Thermal air curtains have basic specifications: Power, air performance and installation height. For these parameters, the selection of heat saves is calculated. Also important dimensions are also important, and more precisely the width of the curtain - it should be sufficient to overlap the entire doorway, providing full-fledged protection.
Thermal curtains are most often produced in horizontal performance and are placed above the door or gate on the wall or ceiling. Curtains vertical installation Are posted on the side of the doorway and have an important characteristic Already not width, and height. Sometimes, at high doorwayThe use of several such curtains installed on each other. There are also models of universal installation that are connected on the side or from above at the request of the user. Thermal curtains often have a remote remote control - key, wired or wireless. Such a device significantly facilitates the use of the veil and increases comfort. A large assortment The thermal curtains are presented below on the page and in the site menu.
