ELEVATOR IN USE FOR A CLIMATE CONTROL IN A BUILDING

Abstract

A method of monitors a climate quality within a building having an elevator running between floors of an elevator hoistway. The elevator car of the elevator includes at least an air-quality sensor. The method is characterized in that a fan of the elevator car is running when the door(s) of the car is/are opening at a floor station to suck air from the building's floor level into the elevator car to the vicinity of the air-quality sensor and sensing the air-quality by the sensor preceding to generating data of the air-quality.

Claims

1. Method of controlling a climate quality within a building by means of an elevator system comprising an elevator car that is running between floors of an elevator hoistway of the building, the elevator car of the elevator comprising at least an air-quality sensor, the method comprises the steps of controlling a fan of the elevator car to at least run when the door(s) of the car is/are detected to be open or opening at a floor level station to therewith suck air from the building's floor level into the elevator car to the vicinity of the sensor and sensing sensor specific parameter(s) by the sensor, wherein further the floor-level-position of the elevator car is detected and the acquired sensor data are allocated to the position data of the car as gained by the position detection.

2. Method according to claim 1, wherein when the car door(s) is/are open a floor level is verified from the position data of the car, wherein acquired sensor data are allocated to said verified floor as long as the door(s) will be opened again on a different floor level.

3. Method according to claim 1, wherein the fan is switched on by a controller simultaneously when starting an opening process of the car door(s) and switching the fan off when closing the door(s), wherein sensing the climate data only while running the fan.

4. Method according to claim 1, wherein sensing of the climate parameter(s) starts after a time-lapse of a preset time delay.

5. Method according to claim 1, wherein sensing of the climate parameter(s) is only carried out when the car is empty.

6. Method according to claim 1, further comprising sending the climate data as acquired for the floor levels to a mobile smart-gadget visualizing therewith the actual prevailing climate conditions within the building.

7. Method according to claim 1, further comprising sending the acquired data to a controller linked to an HVAC-system of the building for further processing said data and adapting the climate quality accordingly.

8. Method according to claim 1, wherein measuring the climate quality encompasses measuring by means of a convenient sensor the temperature, humidity, air pressure, volatile organic compounds, small particles of air pollution, floor level noises.

9. Method according to claim 1, further comprising stopping a time window within which a measuring of sensing any climate parameter was missing, wherein a threshold value for a maximum time window is defined, the exceedance of which triggers an activation of said controlling method.

10. Method according to claim 5, wherein a time window is stopped for each floor level individually, so that an activation of the controlling method can be started for each floor level individually.

11. Method according to claim 1, wherein the data as gained are combined with further data as gained by an air quality sensing system installed in the building.

12. Method according to claim 1, wherein the elevator controller receives and/or exchanges commands with the HVAC-controller of the building.

13. Method according to claim 1, wherein the elevator controller is configured such to start the control method including a travel action of the car moving from floor to floor and opening the door(s) at each floor, respectively.

14. Elevator system including an elevator controller and being configured to carry out the method according to claim 1.

15. Method according to claim 2, wherein sensing of the climate parameter(s) starts after a time-lapse of a preset time delay.

16. Method according to claim 3, wherein sensing of the climate parameter(s) starts after a time-lapse of a preset time delay.

17. Method according to claim 2, wherein sensing of the climate parameter(s) is only carried out when the car is empty.

18. Method according to claim 3, wherein sensing of the climate parameter(s) is only carried out when the car is empty.

19. Method according to claim 4, wherein sensing of the climate parameter(s) is only carried out when the car is empty.

20. Method according to claim 2, further comprising sending the climate data as acquired for the floor levels to a mobile smart-gadget visualizing therewith the actual prevailing climate conditions within the building.

Description

[0040] In the following, the invention is elucidated by means of an embodiment shown in the drawings. In these,

[0041] FIG. 1 is a perspective view of an elevator moving in its hoistway;

[0042] FIG. 2 is a schematic view showing the functioning of the invention

[0043] In FIG. 1 an elevator system is to be seen serving several floor levels 4. In the middle floor level there is an elevator car 10 stopping with car doors 18 opened so that the inner space 8 of the car 10 is in air exchange with the air of the respective floor level 4. Any data which are gained or sent to the car are transmitted via a cable 6 to the controller of the elevator system.

[0044] When now having a look into FIG. 2, the invention becomes clear in view of that when the car doors 18 are opened, at least then, the fan 14 in the ceiling of the elevator car 10 is triggered to be switched on. This in turn leads to that the air of inside the car is ventilated and pushed into the hoistway 12, what also leads to that air of the floor level 4 is sucked into the cabin of the car creating therewith an air flow 20 into it. Since this air flow 20 continues up to the fan 14 and further on into the hoistway space, the air flow 20 is directed to the air quality sensor 16 which is creating data of the quality of the air as sucked in from the floor level 4. These data can be sent via the cabling 6 to the elevator controller for any further evaluation. When integrating these data into the building automation any ventilation of air within the building can be adapted by the data as gathered by the quality sensor 16 within the car 10. Due to that the car is moving between the several floors 4, it is an easy way to gather air quality data from each floor level 4 by means of the moving car.
