Abstract

A method of operating an air conditioning system to condition air in a plurality of closed areas in a building, which has the steps of delivering a stream of air conditioning at a relatively constant cold temperature level to a terminal provided in each of the areas, regulate the amount of relatively cold air conditioning discharged in the area according to the level of temperature in it, generate a control signal, varying the magnitude of the same according to the amount of air conditioning at constant temperature supplied to the area, characterized by the phases of monitoring the magnitude of the control signal, and activating a hot air supply terminal when the magnitude of the control signal indicates that the amount of relatively cold air at constant temperature discharged in the area it has decreased below a predetermined level.
