Abstract:
A method for heating and/or air conditioning of premises, comprising at least one service room (15), and at least two main rooms (8,9,10), consisting of:using an external unit (50; 51) and at least one internal unit (1), the external unit (50; 51) comprising means for regulation with variable power and an exchanger, and each internal unit (1) comprising an air take-up unit (2), means for ventilation with a variable throughput and power and an exchanger, and being designed to assure the heating and/or air conditioning of at least two main rooms (8,9,10); discharging a given volume of stagnant air; conveying a given volume of renewed air to the air take-up units (2) of each internal unit (1); mixing the renewed air and the air taken up in each internal unit (1), upstream from the exchanger of the latter; blowing the mixture of renewed air/heated and/or cooled air taken up, into each main room (8,9,10), through at least one blower aperture (5,6,7) which is supplied by an internal unit (1), and each of which is associated with means for motorisation, which can make it possible to modify the position of opening of the said apertures; and regulating the temperature in each main room (8,9,10), by means of temperature measurement means (33; 38), with which the means for motorisation of the blower apertures (5,6,7) are associated, such as to obtain positioning of each of these apertures which can make it possible to maintain each of the said main rooms at a pre-determined set temperature, the said method being wherein a central control unit (48) is used, which is connected to the external (50; 51) and internal unit(s) (1), the means for motorisation of each blower aperture (5,6,7), and the means for measurement of the temperature (33; 38), and is programmed to be configured: either in a mode for control of the temperatures of the rooms (8,9,10), during which: it controls the external (50; 51) and internal unit(s) (1) and the means for motorisation of the blower apertures (5,6,7), according to the information received from the means for measurement of the temperature (33; 38), such as to maintain the set temperature in each main room (8,9,10); it determines the position of the means for motorisation of each blower aperture (5,6,7), such as to detect any total closure of the (or all of the) aperture(s) which supply/supplies a main room (8,9,10); and, if all the apertures (5, and/or 6, and/or 7) which supply at least one main room (8, and/or 9, and/or 10) are closed, it is configured in a mode for control of renewed air, during which: it measures the time of closure of the said aperture(s) (5,6,7) closed; after a time of closure of the said aperture(s), which is greater than a pre-determined threshold, it calculates the deficit in the supply of renewed air in each room (8,9,10) not supplied, and controls the means for motorisation of all the blower apertures (5,6,7), such as to open each blower aperture initially closed, and to close the blower apertures initially opened of the rooms, for a period of time which is designed to make up for the deficit in the supply of renewed air in each room not initially supplied; and it is reconfigured in the temperature control mode in the main rooms, when the deficit in the supply of renewed air has been made up.
