JP-A-9-318134

  As described above, a device that monitors the operating state of an air conditioner and performs energy-saving operation control by remote control or the like has been conventionally developed. In this case, since the indoor set temperature is changed regardless of the presence / absence of the room, there is a possibility that the room becomes uncomfortable.

  Further, when the room set temperature is changed in the energy saving operation mode, if the change width becomes too large, it takes time to return to a comfortable room temperature at the time of occupancy, and a rapid increase in energy consumption occurs.

  Conventionally, the energy-saving operation is canceled manually or by changing the indoor heat load in the room or the like. In this case, when the person returns to the room, the comfortable room temperature at the time of occupancy is not reached, and it takes time for the temperature to be restored, resulting in a rapid increase in energy consumption.

(Object of invention)
The first object of the present invention is to return to a comfortable thermal state when returning from the outside in the energy saving operation mode, and to temporarily avoid consuming a large amount of energy.

The calorific value harmony apparatus having an energy saving operation function when going out, which raises or lowers the set temperature by a predetermined value in accordance with the increase or decrease of the deviation distance or deviation time transmitted from the deviation measurement communication means.

  In order to achieve the second object, the present invention according to claim 2 confirms locking of a building in which a calorie adjusting device is installed, and notifies the remote control means of locking, Absence confirmation means for confirming absence in a building and notifying to the remote control means, the remote control means in the energy saving operation mode, after the lock confirmation and absence confirmation are notified, the deviation measurement communication means The calorific value harmony apparatus which has an energy saving operation function at the time of going out of Claim 1 which raises / lowers said set temperature by predetermined value for every increase / decrease in the deviation distance or deviation time transmitted from.

  According to the first aspect of the present invention, in the energy saving operation mode, when returning from going out, it is possible to return to a comfortable thermal state, and to temporarily consume a large amount of energy. Can be eliminated.

  Furthermore, according to the second aspect of the present invention, in the energy saving operation mode, it is possible to surely save energy when going out.

  The best mode for carrying out the present invention is as described in Examples described later.

  FIG. 1 is a diagram illustrating a configuration example of an air conditioner according to an embodiment of the present invention. An air conditioner main body 1 includes an indoor unit 2, an outdoor unit 3, a control circuit 4, an indoor temperature sensor 5, and an outdoor temperature sensor 6. The indoor unit 2 has an indoor heat exchanger 7, an indoor blower 8, and an indoor expander 9, and the outdoor unit 3 has a compressor 10, a four-way valve 11, an outdoor heat exchanger 12, and an outdoor expander 13. Although the air conditioner main body 1 is shown in FIG. 1 as a heat pump system, the heat source system may be another system as long as it has a similar function. The control circuit 4 is configured by, for example, a microcomputer, and controls the indoor unit 2 and the outdoor unit 3 by setting operation / stop, indoor set temperature, energy saving operation mode, other operation modes, operation wind speed, and the like. Reference numeral 14 denotes a remote controller disposed away from the air conditioner main body 1. The room temperature setting means 15 sets the room temperature by operating an operation panel (not shown), and the set room temperature is set wirelessly or by wire. There is set temperature notification means 16 for notifying the control circuit 4 and receiving a response from the control circuit 4. For example, a personal computer or a home server is suitable as the remote controller 14.

  Reference numeral 17 denotes a divergence measurement communication means which is the same as when going out, and is preferably provided integrally with a mobile phone or an in-vehicle car navigation device. The deviation measurement communication means 17 includes a measurement means 18 and a communication means 19, and the measurement means 18 is a current deviation measurement communication means by a global orientation system (GPS) using an artificial satellite 20 as shown in FIG. 17 positions are detected, and then the position of the remote controller 14 is detected in the same way (the measuring means 18 may store the position of the remote controller 14 measured in advance) between the two positions. The distance, that is, the deviation distance is calculated (or the deviation distance is converted into the deviation time). The communication means 19 transmits the measured deviation distance or deviation time (hereinafter simply referred to as deviation distance) to the remote controller 14 by radio or wire.

  Reference numeral 21 denotes locking confirmation means for detecting the locking state of the building in which the air conditioner main body 1 is installed, and transmitting the locking state to the remote controller 14 by radio or wire. Reference numeral 22 denotes absence confirmation means for detecting that the building in which the air conditioner main body 1 is installed is absent, and transmitting the detection result to the remote controller 14 by radio or wire. For example, as shown in FIG. 3, the absence confirmation means 22 includes a human sensor 24 provided in each of the main rooms 23, and a remote controller that sends an absence confirmation signal when all human sensors 24 do not detect a human body. 14 is a communication means for transmitting wirelessly or by wire.

  The operation of the remote controller 14 when the control circuit 4 controls the air conditioner body 1 in the energy saving operation mode will be described with reference to FIG. The energy saving operation mode can also be set by the remote controller 14. In step S1, the deviation distance measured by the deviation measurement communication means 17 is monitored, it is determined whether or not it exceeds a predetermined range, and if it exceeds the predetermined range, the process proceeds to step S2. This predetermined range is for excluding the outing range where the user can go home immediately.

  In step S2, the locking information from the locking confirmation means 21 is confirmed. When confirmed, the absence information from the absence confirmation means 22 is confirmed in step S3. By confirming both the locking information and the absence information, it is possible to reliably recognize the necessity of energy saving operation.

  After confirming the locking and absence, the process proceeds to step S4, where the deviation distance is received from the deviation measurement communication means 17 and confirmed. When there are a plurality of deviation measurement communication means 17, a value having the smallest deviation distance is set as a representative value. If this value is within the predetermined range, the process returns to step S1, and if it exceeds the predetermined range, the value is increased or decreased by a predetermined value within the set temperature change range that is predetermined according to the increase / decrease of the deviation distance by the table in step S5. Calculate the set temperature. In step S6, the calculated set temperature is transmitted to the control circuit 4, and the control circuit 4 changes the set temperature to the calculated set temperature and controls the operation of the air conditioner body 1 so that the changed set temperature is obtained. To do. The control circuit 4 transmits a response indicating that the set temperature has been changed as instructed, and the remote controller 14 receives the response in step S7. In this case, depending on the type of the air conditioner, there are some that cannot respond that the set temperature has been changed. In this case, the remote controller 14 reads and checks the set temperature of the control circuit 4.

  The range (ΔT) of the set temperature change sent from the remote controller 14 to the control circuit 4 is determined in advance with respect to the increasing / decreasing distance (ΔL). When the deviation distance increases, the set temperature is increased by ΔT during cooling operation and the set temperature is decreased by ΔT during heating operation for each increase of the deviation distance ΔL. When the deviation distance decreases, the set temperature is decreased by ΔT during the cooling operation every time the deviation distance ΔL is decreased, and the set temperature is increased by ΔT during the heating operation. As a result, the operating rate of the air conditioner body 1 can be reduced and energy saving can be achieved. In addition, when returning home, a comfortable temperature environment is provided, and by gradually heating and cooling, it is possible to eliminate temporarily consuming a large amount of energy.

  In step S1, it is determined whether or not the deviation distance exceeds a predetermined range. However, it may be determined whether or not an elapsed time after entering the energy saving operation mode exceeds a predetermined time. Good.

  The present invention can be applied not only to an air conditioner but also to a water heater, a bath heating device, a floor heating device, and the like.
