Appointment shield ventilation control
If you want to enable or set up domestic split-system or apparatus ventilationFixed in the hole ventkanala, no control nodes are not required - each device controlled manually or by remote d / y.
But if the length of a large network, and the devices are installed in inaccessible places, in mines, on the roof or the attic, in dedicated niches inside walls - the need arises to install remote unit management.
All information about the heaters, convectors, the individual fan is supplied in a single center - SCHUV. Here are the machines responsible for the operation and regulation instruments
Modern SCHUV represent panel with indicator control devices or metal cabinets, which are mounted on the floor or hung on the wall. To protect the internal filling are provided hinged doors, lockable. In addition to the abbreviations can be found SCHUV SHUV (cabinet).
Basic functions SCHUV:
- control of the equipment included in the ventilation and air conditioning systems;
- protection units from the occurrence of overheating, incorrect installation and connection, short circuit protection;
- adjustment of the most important parameters of the equipment, such as performance or power;
- programming of the entire system or individual units to a specified time period - day, week, month;
- Indicating that facilitates control and adjustment;
- maintaining a certain temperature in the different rooms, the possibility of rapid change of its parameters;
- control over the internal walls of the duct and the degree of filter contamination;
- Warning malfunction seasonally dependent equipment, e.g., water heaters, which may be frozen at too low a temperature.
Installation of electrical switchboard in a business or residential building allows service personnel monitor the operation of the equipment from one place and to quickly respond to breakdowns and stop individual devices. Apparatus regulating fire fighting and partly heating device also can be placed in the same cabinet.
Scheme SHUPVV installation. Cabinets can be a common, unifying all units in the building and serving a separate floor, wing, plant, section, etc.
In the event of an emergency such as a fire in one of the rooms, ventilation stop is automatically or manually - to SCHUV panel.
Features SCHUV device
Installation and integration of control panels produced by the rules and regulations that dictate the state documents, such as GOST R 51321.1. Cabinets for pumps and electrical, ventilation and air conditioning systems, panels are mounted in the hallways, utility rooms or in specially designated areas - of shield.
If the building has the capacity, all control units, including ventilation and fire is set in the control room.
The room where the panel board is located, should be observed room temperature, normal humidity level. All devices must be protected against direct from / f rays and dust, as well as the magnetic fluctuations and radio interference
Electrical equipment manufacturers offer a variety of configurations that vary in size, functionality, degree of protection and programming level. The simplest modifications are intended to serve the private residential property complex - businesses and public buildings.
Requirements to complete control panels
When choosing SHUV oriented to the working area size, the ability to install the necessary equipment, ergonomics and safety. The last point concerns both the installers regularly serving network, and people who may be nearby.
The main requirements for SHUV SCHUV and are as follows:
- Shield must contain all system management tools ventilation and air conditioning;
- important components necessary to provide the display, light, digital, or connected to a PC;
- devices that are responsible for the most significant equipment must have dual controls - automatic and manual.
All devices are carefully placed on the same plane. Options should be as simple and easy to understand. If the assembly of the ventilation panel to make all the rules, then, if necessary, even to the ignorant person can turn off electrical emergency devices.
Modern control units are made with the possibility of energy saving. Suppose a properly fitted automatic devices are able to reduce costs by 50-65%
Content and functionality of the panels may vary. For example, some required frequency converter systems while others do without it. Maximum user-friendly are the cabinets and panels with automatic and remote / y.
Overview of operating elements
Structurally SHUV - a plastic or metal housing of a rectangular shape having the desired degree of protection IP 45. If the operating conditions are associated with increased risk, the higher protection class.
Inside the housing has devices such as a power supply, controller, transducers. Several circuit breakers are responsible for the separate devices: heaters, recuperators, ventilators, coolers etc.
Required element - hand control. Also needed alarm unit which is activated in an emergency situation and generates an alert light or audible signals.
Trims and terminals for the installation of electrical appliances and their commutation with wires look the same as the counterparts for electrical switchboards
The controls are and sensors. It's kind of receptor, collecting a variety of information about the state of the system and its environment.
They remove air temperature and the devices themselves, the degree of gas concentration or contamination of the elements, measured air velocity et al. The data obtained are fed to the automatic controllers, and there is a correction operation of system elements.
Function sensors are divided into the following types:
- temperature;
- humidity;
- speed;
- pressure and others.
The temperature can be both digital and analog. The signal of the sharp increase or decrease of the temperature inside the premises switch can cause the system to another mode.
On the same principle are humidity sensors. As there is a movement of air masses inside vents can be found thanks to the speed and pressure sensors. On-site sensors are divided into external and internal. First remove the data in the premises, the second, also known as atmospheric or street - outside buildings.
Also, the ventilation channel sensors are, that is mounted inside the duct, either on the walls or across the air flow. They are versatile and can transmit a large amount of information such as temperature, pressure, air velocity
Part of sensors fixed to the surface of the parts to be controlled. They remove the parameters of the devices themselves, such as winding temperature, rotation speed, etc..
Mounting the sensor is accompanied by careful selection. On the one hand, the more information, the better the system works, but on the other operation and network maintenance becomes costly in terms of energy consumption.
The sensors coupled to the controllers work. These are the devices that receive information and process it in the automatic mode. They can be called mediators, since the signal is transmitted on the executive devices: air flow switches, fans, refrigeration, heaters.
For installation inside SHUV more than any other controllers with microprocessors suitable. They are compact in size and do not require a large area for installation
Particularly popular generic type controllers, which are both capable of processing information from the various systems of ventilation, heating and others.
Recommendations for assembly SHUV
Installation and testing SCHUV should engage personnel with the appropriate qualifications, self-assemble and connect elements within the panel or cabinet is not only recommended, but also prohibited.
Housing is not made by the hands, and is obtained commercially or order-specific ventilation system. Together with the body kit is supplied devices: circuit breakers, controllers, power supplies, switches, security elements and wires.
Often it occurs such that a set of devices and components not staffed full - there is no wiring or circuit-breakers. When parts need to save transoms matching specifications (e.g., wire size, or machine power current).
Set of elements SCHUV accompanied by a diagram on which are assembled. Any deviations from the scheme can lead the incorrect operation or breakdown art
Before the order is necessary to make a list of all devices that are part of the ventilation system, as well as make suggestions regarding the mode switching, the controller type, the presence of certain sensors. In some SCHUV instead of the controller sets the relay.
Examples SCHUV sample can serve the following technical characteristics:
- nom. frequency - 50 Hz;
- voltage - 380 V;
- voltage connected Fan - 220;
- motor power - 22 kW;
- the level of protection - IP65;
- Sizes - 400h800h180 mm;
- service life - 10 years.
Finished models are marked with symbols, which contains information about the modification and its frame size, the degree of protection, a climatic performance, room TU or GOST. In the latter case, the producers are guided by GOST 14254 and GOST 15150.
Benefits of professional installation
According to the rules, installation and maintenance ventilation systemsAnd SCHUV should engage professionals with an engineering degree. They bear full responsibility for improper selection, installation, connection devices, as well as for the maintenance of technical equipment in an improper or dangerous condition.
To correctly determine the content panel or cabinet installers do full monitoring of the ventilation system.
Then proceed as follows:
- analyze the load;
- select the optimal scheme;
- determine the modes of operation of devices in order to increase efficiency;
- pick up the equipment.
Assembly itself takes a bit of time: all devices in turn are mounted in several rows, wires neatly attached to the terminals, and laid along the lines of organized bundles, then output out.
One of connectivity options, wherein NK1 and NK2 - channel type heating devices; M1 - 3-phase fan; A, B, C - a connection network, N - neutral, PE - earth; Q - overheat safety thermostat; Y - thermostat of protection
Professional installers have experience installing and operating SCHUV, so is unlikely to be mistaken with a choice of models and nuances accession instruments. In addition, they are well versed in the circuits systems of ventilation of apartments and country houses, and can quickly determine the presence of errors in the drawing.
If time does not figure and connect the devices on the wrong scheme - and this also happens - you can create an emergency situation.
Sales and marketing of boards and cabinets has been many companies that produce or sell ventilation, refrigeration and heating equipment. For example, in Moscow, it can be done in the "Ruklimat" companies, "Rowan", "AB-Automatic", "Galvent" and others.

Video review - the sample assembly SHUV with heater:
Automation of the ventilation or any other system - the process of important and expensive. If you choose the wrong equipment or make the assembly, it may be an accident as a result of which people suffer, for example, at a chemical plant.
At least, fails appliances, also expensive. For these reasons, the installation SCHUV from the initial design stage to the end should deal exclusively with professionals.
