Preview control systems for HVAC
- Concordia Univ., Montreal, Quebec (Canada). Centre for Building Studies
The application of preview control to heating, ventilating, and air-conditioning (HVAC) systems is explored. A multizone space-heating (MZSH) system consisting of a boiler, two heat pumps (one for each zone), two environmental zones, and the associated distribution network is considered The system consists of five controllers. The control problem is to maintain the zone temperatures and the boiler temperature at some specified setpoints irrespective of the changes in space-heating loads acting on the zones. By treating the disturbances (such as outdoor temperatures) as previewable, decentralized preview controllers for the MZSH system are designed Simulation results showing the closed-loop responses of the system with and without preview control are given.
