Abstract

A building having a plurality of rooms in at least one zone is heated or cooled by heating or cooling a heat-transfer, medium outside the rooms, conducting the heated or cooled medium through conduits to the rooms, and providing a respective controller for each zone. Respective heating/cooling parameters are established for each zone by predetermination or measurement, and the heating or cooling of each zone with the heat-transfer medium is controlled by means of the controllers in accordance with the respective parameters by regulating the amount of the medium conducted to the zone or a temperature of the medium conducted to the zone.

Claims

1. A method of heating or cooling a building having a plurality of rooms in at least one zone, the method comprising the steps of:

heating or cooling a heat-transfer medium outside the rooms;

conducting the heated or cooled medium through conduits to the rooms;

providing a respective controller for each zone;

establishing respective heating/cooling parameters for each zone by predetermination or measurement; and

controlling the heating or cooling of each zone with the heat-transfer medium by means of the respective controller in accordance with the respective parameters by regulating the amount of the medium conducted to the zone or a temperature of the medium conducted to the zone.

2. The method defined in claim 1 wherein the heat-transfer medium is heated or cooled by means of a heat pump.

3. The method defined in claim 1 wherein the heat-transfer medium is only heated outside the room.

4. The method defined in claim 1 wherein the conduits are in the floor, walls, or ceiling of the rooms.

5. The method defined in claim 1 wherein each room has its own zone and controller and the heating or cooling each room by the heat-transfer, medium is controlled by means of the respective controller.

6. The method defined in claim 1 wherein the parameters include priority parameter for each room.

7. The method defined in claim 1 wherein one of the parameters of each room represents a heat-storage capacity of the respective room.

8. The method defined in claim 1 wherein one of the parameters of each room represents a conductivity of a floor covering of the respective room.

9. The method defined in claim 1 wherein one of the parameters of each room is an actual-temperature of the room and another of the parameters of each room is a desired temperature for the room.

10. The method defined in claim 1 wherein the conduits are provided with flow regulators operated by the controllers.

11. The method defined in claim 1 wherein the heating or cooling of each zone is regulated so as to minimize the output level of a heating or cooling appliance serving to heat or cool the heat-transfer medium.

12. An apparatus for heating or cooling a building having a plurality of rooms in at least one zone, the apparatus comprising:

means for heating or cooling a heat-transfer medium outside the rooms;

conduits connected to the heating/cooling means for conducting the heated or cooled medium to the rooms;

a respective controller in each zone; and

control means connected to the controllers and to the heating/cooling means for controlling the heating or cooling of each zone with the heat-transfer medium by means of the respective controller in accordance with respective parameters established by predetermination or measurement by regulating the amount of the medium conducted to the zone or a temperature of the medium conducted to the zone.
