Method and plant for controlling the temperature in an environment

Abstract

Method for controlling the temperature inside an environment, in particular of rooms (S) of a hotel (A) of a complex for residential use and/or office comprising the steps of dynamically defining an average time (T) of travel of a path (C), travelled by a user (U), defined by an entrance (H) of the building or complex (A) to a specific room (S), dynamically detecting an environmental condition outside the room (S), defining a target temperature corresponding to a temperature of the room (S) when a user (U) stays in the room (S) itself and adjusting an environmental control plant of the room (S) so as to maintain the room (S) at a setback temperature corresponding to a temperature in which the room (S) itself is not occupied by a user (U) and taking the room (S) from the setback temperature to the target temperature during the average time (T) of travel of the user (U) from the entrance (H) of the building or complex (A) to the room (S). The setback temperature is defined at least according to the average time (T) of travel, of the external environmental condition, of the target temperature, and of the efficiency of the air conditioning system.

1 . A method for controlling the temperature inside an environment, in particular of rooms (S) of a hotel (A) or of a residential and/or office complex, comprising the steps of:
 defining an average time (T) of travel of a path (C) travelled by a user (U), defined from an entrance (H) of said hotel (A) or residential and/or office complex to a specific room (S);   detecting an environmental condition outside said room (S);
 defining a target temperature corresponding to a temperature of said room (S) when a user (U) stays in the room (S); 
   adjusting an environmental control plant of the room (S) so as to:
 maintain said room (S) at a setback temperature corresponding to a temperature in which the room (S) is not occupied by a user (U); 
 taking said room (S) from said setback temperature to said target temperature during said average time (T) of travel of the user (U) from the entrance (H) of the hotel (A) or residential or office complex to said room (S); 
   
       said setback temperature being defined according to said average time (T) of travel, of said external environmental condition and of said target temperature. 
     
     
         2 . A control method according to  claim 1 , wherein said step of adjusting the environmental control plant is performed in function of the efficiency of the control plant. 
     
     
         3 . A control method according to  claim 1 , wherein said step of defining the average time (T) of travel is performed by calculating an average of travel times that are obtained from a plurality of users who have travelled this path (C). 
     
     
         4 . A method according to  claim 1 , wherein said step of detecting an environmental condition outside said room (S) is performed by detecting a temperature variation along said path (C). 
     
     
         5 . A method according to  claim 1 , wherein said step of detecting an environmental condition outside said room (S) is performed by detecting weather conditions outside said hotel (A) or residential and/or office complex. 
     
     
         6 . A method according to  claim 1 , wherein said step of defining the target temperature is performed a priori or in function of a request of said user (U). 
     
     
         7 . A method according to  claim 1 , comprising a step of defining a database containing data for each room (S) of said hotel (A) or residential and/or office complex, said database containing one or more setback temperatures for each room (S) defined in function of said average time (T) of travel, of said external environmental condition and of said target temperature. 
     
     
         8 . A method according to  claim 1 , comprising a step of defining a database containing for each room (S) of said hotel (A) or residential and/or office complex, said database containing one or more setback temperatures for each room (S) defined in function of said average time (T) of travel, of said external environmental condition and of said target temperature. 
     
     
         9 . An environmental control plant for an environment, in particular a room (S) of a hotel (A) or residential and/or office complex, comprising reading devices for reading the temperature of a room (S) and devices for adjusting the temperature of the room (S), said control plant further comprising a processing unit ( 10 ), connected or connectable to said reading devices and said temperature adjusting devices, configured to perform one or more of the steps of the method according to  claim 1 . 
     
     
         10 . An environmental control plant according to  claim 9 , further comprising reading devices for reading a temperature outside said room (S) and/or of a temperature outside said hotel (A) or residential and/or office complex and/or devices for detecting environmental conditions outside said hotel (A) or residential complex. 
     
     
         11 . A computer program including instructions on performing the steps of the method according to  claim 1 .
