Abstract
An air conditioner includes a human detection sensor and a controller, when the human detection sensor detects that no human is present during execution of the air conditioning operation, is configured to select whether to make a switch to the second power-saving operation after the first power saving operation is performed from the air conditioning operation based on results of detection by the human detection sensor at and after a time at which it is detected that no human is present and the presence/non-presence information at and after the time at which it is detected that no human is present.
Claims13
An air conditioner comprising:
- a human detection sensor that detects whether a human is present in an air conditioning space;
- and
- a controller that is configured to predict whether a human will be present in the air conditioning space and, using presence/non-presence information that is results of predicting whether a human is present, make a switch from an air conditioning operation to a power-saving operation of which power consumption is smaller than the power consumption of the air conditioning operation,
- wherein the power-saving operation includes a first power-saving operation in which a set temperature in the air conditioning operation before the switch to the power-saving operation is changed and of which power consumption is smaller than that of the air conditioning operation before the switch to the power-saving operation and a second power-saving operation in which the air conditioning operation is stopped, and
- when the human detection sensor detects that no human is present during execution of the air conditioning operation, the controller is configured to select whether to make a switch to the second power-saving operation after the first power saving operation is performed from the air conditioning operation based on results of detection by the human detection sensor at and after a time at which it is detected that no human is present and the presence/non-presence information at and after the time at which it is detected that no human is present.
(canceled)
An air conditioning system comprising an air conditioner including a human detection sensor that detects whether a human is present in an air conditioning space;
- a server device that generates a plurality of presence/non-presence patterns that are generated using results of detection by the human detection sensor in the past and that represents a tendency of presence and non-presence of a user in the air conditioning space;
- and a communication adapter that makes communication between the air conditioner and the server device,
- wherein the air conditioning system comprises:
- a presence/non-presence predictor that selects a presence/non-presence pattern from the presence/non-presence patterns using current results of detection by the human detection sensor and that predicts whether a human will be present in the air conditioning space using the selected presence/non-presence pattern;
- and
- a controller that, using presence/non-presence information that is results of predicting whether a human is present, is configured to make a switch from an air conditioning operation to a power-saving operation of which power consumption is smaller than the power consumption of the air conditioning operation;
- and
- wherein the power-saving operation includes a first power-saving operation in which a set temperature in the air conditioning operation before the switch to the power-saving operation is changed and of which power consumption is smaller than that of the air conditioning operation before the switch to the power-saving operation and a second power-saving operation in which the air conditioning operation is stopped, and
- when the human detection sensor detects that no human is present during execution of the air conditioning operation, the controller is configured to select whether to make a switch to the second power-saving operation after the first power saving operation is performed from the air conditioning operation based on results of detection by the human detection sensor at and after a time at which it is detected that no human is present and the presence/non-presence information at and after the time at which it is detected that no human is present.
