  • the time limit used by the second determination unit 374 is a predetermined time determined in advance, and is stored in the time limit storage area 356 of the controller-side storage unit 35.
  • the control unit 372 determines that the elapsed time has exceeded the time limit and the second determination unit 374 determines the energy saving control. Do a new.
  • the control unit 372 Do not perform energy saving control. Note that description of functions similar to those of the control unit 372 of the first embodiment is omitted.
  • the energy saving device 3 receives the state change information from the air conditioner 2 (“Yes” in S31), the state change information is stored in the air conditioning state storage area 351, and the state change information stored in the air conditioning state storage area 351 is stored. Each time, the time information indicating the storage time (current time) at which the state change information is stored is stored in the stable state storage area 352 (S32). If necessary, the energy saving device 3 outputs state change information to the display 5, and the display 5 displays the contents of the state change information (setting state of the air conditioner 2).
  • Step S34 When the user's operation is a non-energy saving operation (S33), the energy saving device 3 sets the energy state to a non-energy saving state (S34). On the other hand, when the user's operation is an energy saving operation (S33), the energy saving apparatus 3 cancels the non-energy saving state (S35). After executing Step S34 or Step S35, the process returns to Step S31. If the user operation is, for example, an off operation (S33), the operation is terminated.
  • the energy saving apparatus 3 When there is no change in the setting state of the air conditioner 2 (“No” in S31), the energy saving apparatus 3 refers to the latest setting state stored in the air conditioning state storage area 351. When the energy state is the non-energy saving state (“Yes” in S36), the difference between the current time and the storage time stored in the stable state storage area 352 corresponding to the latest set state is the determination value storage area. If the threshold value stored in 353 is exceeded (S37), the energy saving apparatus 3 sets the current time to the energy saving execution time when the difference between the current time and the energy saving execution time is longer than the time limit ("Yes" in S38).
  • step S39 energy saving control is performed in a direction to reduce the load on the air conditioner 2 so that the set temperature of the air conditioner 2 is set to 28 degrees (S40). Thereafter, the energy saving device 3 cancels the non-energy saving state (S41).
  • step S38 when the difference between the current time and the energy saving execution time is equal to or shorter than the time limit (“No” in S38), the operation ends.
  • step S36 when the energy state is not a non-energy saving state (“No” in S36), in step S37, if the difference does not exceed the threshold value (“No” in S37), the process returns to step S31.

Abstract

L'invention concerne un système d'économie d'énergie (1) comprenant : un dispositif de conditionnement d'air (2) qui modifie la température de l'air d'un espace de conditionnement d'air cible; et un dispositif d'économie d'énergie (3) qui commande le dispositif de conditionnement d'air (2). Le dispositif d'économie d'énergie (3) comprend une unité de détermination et une unité de commande. L'unité de détermination détermine que le dispositif de conditionnement d'air (2) a atteint un fonctionnement stable une fois que le dispositif de conditionnement d'air (2) a fonctionné dans un état stable pendant une durée prédéfinie après que le dispositif de conditionnement d'air (2) a modifié un réglage conformément à une opération de réglage. L'unité de commande exécute une commande d'économie d'énergie qui modifie les réglages du dispositif de conditionnement d'air (2) dans un sens qui réduit la charge du dispositif de conditionnement d'air (2), si l'unité de détermination a déterminé que le dispositif de conditionnement d'air (2) a atteint un fonctionnement stable.
