Abstract

The present invention relates to an air conditioning system for use in a building arranged in a plurality of zones in each of which the air temperature can be separately controlled. The system comprises two air supply ducts (1, 2) from each of which either heating or cooling air can be supplied to each zone and an individual terminal unit (3) in each zone to which ducts (1, 2) are connected and controllable to determine the air flow rate into the zone at any instant. There is a temperature sensor (6) in each zone, a central control means (9) common to all zones which controls the temperature of the air supplied and the air flow rate in each duct in dependence upon signals sent to the central control means from each zone. There is also a communication network (7) linking the central control means to each zone over which signals are transmitted between the central control means and the zones to control operation of the system.
