AUTOMATION SYSTEMS FOR VENTILATION AND AIR CONDITIONING

Get consultation

Automation systems for ventilation is a key task and a basis for reliable functioning of utility equipment, low power consumption and comfortable conditions for people.

Automation systems for ventilation enable to control climatic equipment without permanent operator participation, which eliminates errors caused by the human factor.

MAIN FUNCTIONS OF VENTILATION SYSTEM AUTOMATION (VSA):

maintaining of fixed microclimate parameters in premises (temperature, humidity and quality of air)
automatic switch between Winter/Summer modes according to the environment temperature sensor
automatic switch into an economy mode according to the schedule for electrical power saving
measurement of inlet air consumption according to the air quality sensor (СО2)
recuperation of exhaust air heat
filter contamination control
protection of heat exchangers from freezing
protection of ventilation equipment from failure
timely informing of the service personnel in case of emergency situations
possibility of integration in the high level dispatching system with standard protocols
stop of ventilation on Fire signal

VENTILATION CONTROL CABINETS

ST Solution supplies a wide range of standard cabinets for ventilation control. The advantages of these cabinets are an optimal price and fast delivery terms.

If necessary, according to the Client request, we can produce unstandardized control cabinets with consideration of special project requirements. The company cooperates with leading world and Russian producers of controllers and components, such as Danfoss, ABB, Schneider, Siemens, Carel, Beckhoff, Rockwell, Mitsubishi and others.

Each control cabinet is checked by the Quality Department, packed with a datasheet and operating manual and has all the necessary certificates of the RF and the Customs Union.

AUTOMATION AND DISPATCHING FOR VENTILATION

The supplied automation cabinets are connected to the high level dispatching system via standard protocols (Modbus RS485, Modbus TCP, Profibus, Profinet, BacNet, Lonworks etc.)

AIR CONDITIONING SYSTEM AUTOMATION

Modern centralized conditioning systems are strongly integrated with ventilation systems. For example, intake systems may comprise water and freon heat exchangers. To control microclimate of separate premises, fancoils and climatic bars connected to chillers are used. Our company also performs automation for air conditioning and coordination of refrigerating equipment with other building utility systems.

MIXING UNITS

ST Solution has a wide range of mixing units for ventilation equipment and the warehouse.
Mixing unit is a compact device designed for smooth control of operability and protection of fluid heat exchanger by measuring the inlet temperature of heat carrier at its constant flow.
Thanks to the improved design (three way valve and pump are located at the return water line), mixing units may be used with the heat carrier temperature of up to 130°C (recommended temperature is 110°C) enabling reliable protection from freezing of water heater and exact maintaining of intake air temperature.

If necessary, according to the Client request, we can produce unstandardized mixing units with consideration of special project requirements.

All products pass hydraulic tests by the Quality Department under the pressure of 10 bar and have certificates of the Customs Union and of the RF.

WORK STAGES

Designing of Automation Systems for Ventilation and Conditioning

Appropriate designing reduces the production period of control cabinets, accelerates the implementation of electrical mounting works and enables to optimize the project cost.
Depending on the task we may use standard control cabinets and mixing units with minimum price and delivery terms or unstandardized cabinets and mixing units specially developed in accordance with the Customer requirements for a certain facility.
The typical scope of detailed documentation on ventilation system automation (VSA section) comprises the following:

general data with an explanatory note
functional automation diagrams
equipment and external wiring layout plan
schematic diagrams of control cabinets
external connection circuits
cable log
equipment and mounting material specification
typical mounting drawings

Mounting of Automation Systems for Ventilation and Conditioning

Electrical mounting works of ventilation automation systems are implemented according to current standards and additional Customer requirements formed at the agreement stage of Terms of Reference.
The work is done by qualified specialists having a long-term implementation experience of different complexity projects.
Our employees have required protective equipment for safe implementation of works at special hazardous facilities (special clothing, helmets, safety vests, shoes with steel tips, safety belts, safety glasses etc.)
We use only quality mounting materials and electrical tools and we are partners of leading producers in the industry.

Commissioning Work

The stage of commissioning work comprises checking of the key functions of the building ventilation automation system:

laboratory electrical tests and issuing a technical report
instrumentation adjustment with issuing of corresponding reports
individual test of ventilation equipment, check of protective functions and trips, check of operation algorithms
complex testing of the building automation system
check for meeting the requirements of the Terms of Reference
setting power saving functions
issuing as-built documentation
consulting Customer Operations Service
