Heating and air-conditioning
TRONIC CONTROL® s.r.o. As a manufacturing company supplies heating, ventilation and air conditioning technology – namely:
Facility Management
When controlling heating, ventilation and cooling the TRONIC 2000® interconnects all parts with a communication bus and provides a fully distributed system connected to a supervisory centre. Each part of the control system has its individual independent controller, which takes control of the corresponding technology (boiler plant, heat exchanger, part of a building, machine room etc.) in accordance with its own software transcription. In addition it communicates on-line with the supervisory centre. All relevant data (process data, meter data, commands, positions etc) are transferred to the supervisory centre. The software for the communication interface is very flexible allowing connection to equipment from third-party suppliers (frequency converters cooling units, ventilation units etc). Fire and security protection systems, lift control etc. can be integrated into the system. The TRONIC 2000® software also contains optional upgrades to cover prediction, adaptive control and optimisation functions.
Boiler plant control
The TRONIC 2000® can control both small boiler rooms as well as large boiler plants with an output of 100MW. For smaller applications the TRONIC T2008E can be used with the T2032CX being used for the larger ones. TOTRON® and BILANCE software packages are able to operate with both of them. The TRONIC 2000® can operate using a cascade function for boiler units which have a serial communication OpenTherm®. Output process parameters such as temperature, flow, pressure, and alarms are sent to the TRONIC 2000® which returns process commands to optimise control and protection using software transcripted parameters. Systems are currently being delivered to the well-known Czech boiler producer Thermona.
Ventilation and air condition control
Control of ventilation and air conditioning units is often done using a pre-set time schedule in accordance with the character of the building or hall (hotel, airport, gymnasium etc).
In each case it is necessary to control temperature and sometimes humidity (in hospitals for example). The day can be split into suitable process parts to reach both quality of control and minimum consumption of energy.
Heat exchanger station control
The TRONIC 2000® is able to provide optimal control and protection of object heat exchanger units. For quality of control special functions are required such as adaptive control with ability to predict control deviation. This system of control is well proven.
Hot water can be produced by direct heating in a metal sheet heat exchanger to a desired temperature of 50 deg C (high speed heating) without a chamber. Such type of control – high speed without chamber- requires a very quick reaction to the changes in temperature of the returned hot water. Adaptive control with prediction of deviation, a fast continuous valve, and temperature sensors with very small traffic delay are able to solve this problem and keep the total amplitude of temperature deviation under 5 deg C.
Building control
Individual control of heating and cooling in each room is a more effective way of saving costs and energy. Our controller TRONIC 2008F is designed for this application (e.g. to control fan-coil units, electromagnetic valves on radiators). This system is used in hotel rooms, offices and in the other places where it is necessary to keep a comfortable environment with the possibility of locally resetting the desired temperature and ventilation.
Our controller connects and communicates with a supervisory centre and staff can set room parameters remotely. Reception activities (door-card system, phone, lifts etc.) can be implemented to our system in the hotel.
Supervisory centre
The TRONIC 2000® has been developed as a fully distributed system and it allows us to build large communication networks and supervisory centres. It allows the connection of equipment from third-party suppliers. A fully distributed system gives the chance of creating new operating and control procedures to solve new customer problems and provides user-friendly communication to the customer information network.
This offers him new process optimisation and balance of supply and demand. The supervisory centre can follow the technology on-line, balance supply and demand, generate printouts of operating conditions, and produce graphical displays of data including fault reports and details of operator intervention.
