US 8,262,442 B2 · Method and system for managing thermal energy in a building with duct for lifting installations

Abstract

The invention concerns an energy management method in a building including a lifting installation with a mobile car in a shaft and a ventilation passage between the shaft and the atmosphere. The method includes the monitoring of at least one state parameter of the lifting installation; the evaluation, in a control unit, of the necessity to ventilate the shaft based on at least one state parameter; the switching of an obturator element associated with the ventilation passage from an open position, wherein the ventilation passages is essentially open, to a closed position, wherein the ventilation passages is at least partially obturated, only when the evaluation indicates that ventilation of the shaft is not required, the obturator element being prestressed in its open position. The invention also concerns an energy management system designed to implement the method according to. The present method and system are particularly suitable for installation of a lift in a low-energy or passive building.

A thermal energy management method in a building comprising a lifting installation with a mobile car in a shaft and a ventilation passage between said shaft and the atmosphere, said method comprising the following steps:

monitoring of at least one state parameter of said lifting installation;
said monitoring of at least one state parameter comprising monitoring of a presence of a person in said lifting installation and/or monitoring of a movement of said car in said shaft;
evaluation, in a control unit, of the necessity to ventilate said shaft based on said state parameter, said control unit concluding to the necessity to ventilate said shaft if one of a presence of a person and/ when a movement of said car is detected;
switching of an obturator element associated with said ventilation passage from an open position, wherein said ventilation passage is essentially open, to a closed position, wherein said ventilation passage is substantially obturated, only when said evaluation indicates that ventilation of said shaft is not required, said obturator element being prestressed to its open position.

A thermal energy management system in a building comprising a lifting installation with a mobile car in a shaft and a ventilation passage between said shaft and the atmosphere, said system further comprising:

an obturator element associated with said ventilation passage, said obturator element being mobile between an open position, wherein said ventilation passage is essentially open, and a closed position, wherein said ventilation passage is substantially obturated;
a prestressing means for maintaining, in a passive state, said obturator element in its open position;
and
a control unit for controlling a position of said obturator element, said control unit comprising means for monitoring at least one state parameter of said lifting installation and for evaluating a necessity to ventilate said shaft, said control unit only allowing switching of said obturator element to a closed position when the evaluation of a necessity to ventilate said shaft indicates that ventilation of said shaft is not required, said means for monitoring at least one state parameter of said lifting installation comprising one of at least one means for detecting a presence of a person in said lifting installation and/ at least one means for detecting a movement of said car in said shaft, said control unit concluding to a necessity to ventilate said shaft when one of a presence of a person and/ when a movement of said car is detected.
