HVAC Simulator

Technical Description

Modern DDC systems integrate control, optimisation and monitoring functions. This benchtop unit simulates a heating circuit with domestic water heating and a ventilation and air conditioning system with mixed air control. Various operating conditions and control modes can be set up. It is also possible to simulate faults in the system and to observe the resulting behaviour. Using the benchtop demonstrator the operation of complex building management systems can be simulated.

Learning Objectives / Experiments

- Programming of digital controllers
- Working with digital controllers
- Fault analysis, fault fixing, operating behaviour of the
system
- Changes to control parameters and their effect

Features

* Simulation of a ventilation and air conditioning
system with domestic water heating
* Compact system with fault switching
* Digital modules from central building control systems
