Equipment Set Building HVAC Controls

Building management systems in the digital age
Most modern commercial buildings have heating, ventilation and air conditioning (HVAC) systems that are controlled automatically. HVAC control systems control the temperature, airflow, humidity and carbon-dioxide content of rooms based on the temperatures inside and outside of the building in question. This keeps the climate in the rooms pleasant and the power consumption low.

Modern HVAC systems contain a wide range of technologies and complex control systems. In order to ensure smooth and efficient operation, installation and maintenance engineers must possess an in-depth understanding of how these systems work. Our learning system provides the perfect foundations for teaching this knowledge and providing practical training using real-life components.

Practical training

The Building management systems learning system is the ideal medium for teaching the basics of modern control systems to the level required for training in the field of HVAC. The system possesses industry-standard components provided by Johnson Controls, a world-renowned manufacturer.

Web-based supervisory controller

A built-in web server that acts as an HMI interface can be used to access all the system data in real time via LAN or WLAN. The graphic overview enables the students to keep an eye on the ventilation system and ventilation shafts at all times. Other special functions include time sequence control, forecast displays and alarm management.

Simulated signals, real control

The HVAC system plan module models a typical air conditioning system with simplified building ventilation shafts. This provides the foundation for the learning system. This module can be used to easily simulate change in temperature, pressure and carbon dioxide concentration. It also contains simulated flaps, cooling and heating equipment, fans and humidifiers.

The module's sensor and actuator simulations are connected to a real field controller. This gives the students practical experience of how an HVAC control system responds to changes in conditions. The field controller's control algorithm has been optimized to speed up the processes modeled in the system.
