First experience of the control system of HVAC based on KNX fieldbus applied in intelligent buildings laboratory

Abstract

A new multipurpose laboratory of building technology has been built in Tomas Bata University, Faculty of Applied Informatics and set into test operation. The laboratory supports several subjects like modem HVAC system applications, with renewable sources of energy implemented (solar collectors and reversible heat pump application), and a comprehensive system of control, based on the open bus communication system KNX (c), communication gate based on the TCP/IP protocol. The laboratory is as well equipped as a training tool for control systems based on bus communication particularly KNX (c) (finished) and LONWORKS (c) and BACNET (c) (under construction). The paper describes the first results achieved by the laboratory.
