FIG. 6 shows the first embodiment and is a flowchart showing an example of the operation of the indoor control device and the remote control device. First, when the air conditioner is stopped, the remote controller 1 displays the electricity bill (fuel consumption) per unit time, when the dedicated button 11 of the remote controller 1 is pressed, or when the movement of the remote controller 1 is detected. An example displayed in FIG.

  When the indoor control device receives an OFF signal of the operation on / off button 3 from the remote controller 1 during the previous operation, the indoor control device calculates and stores the integrated power amount α per unit time and calculates the setting information average value β during operation. -Memorize (S10). This S10 is used as the calculation / storage unit for the integrated electric energy per unit time and the setting information average value during operation. Then, the transmission unit 23 of the indoor unit transmits the integrated power amount α per unit time and the setting information average value β during operation (S11), and the reception unit 13 of the remote controller 1 receives the remote controller microcomputer (not shown). (S20) (communication X). Further, the indoor control device turns off the power and the air conditioner stops (S12). Let S11 be a transmission unit that transmits the integrated power amount per unit time and the setting information average value during operation to the remote control device.

  Thereafter, the remote controller 1 enters a standby state in a state where the integrated power amount α per unit time and the setting information average value β during operation are stored in the remote control microcomputer.

  Next, when the dedicated button 11 of the remote control 1 is pressed or the movement of the remote control 1 is detected (S21), the remote control 1 stores the integrated power amount α per unit time stored in the remote control microcomputer and the setting. Based on a comparison value between the information average value β and the setting content currently set in the remote controller 1, it is converted from the predicted value of the integrated electric energy per unit time when the operation is started with the setting content, or converted from the integrated electric energy. A predicted value of electricity bill per unit time (fuel consumption) or a predicted value of CO2 emission per unit time is calculated (predicted) by the remote control microcomputer (S22) and displayed on the display unit 2 (S23). In FIG. 6, the predicted value of the CO2 emission amount per unit time is not shown.

  FIGS. 7 to 10 are diagrams showing the first embodiment, FIG. 7 is a diagram showing a display example displayed before driving in the case of carrying out human-centered control, and FIG. 8 is a case of carrying out control of the entire room. The figure which shows the example of a display which displays an estimated fuel consumption before a driving | operation, FIG. 9 is the figure which shows the example of a display which displays an estimated fuel consumption before a driving | running | working simultaneously when performing a person-centered control and the control of the whole room, FIG. 10 is a diagram illustrating a display example in which the predicted fuel consumption, the current setting, and the current room temperature state are displayed at a time before driving when performing human-centered control. A display example of the predicted value (fuel consumption) of the electricity bill displayed on the display unit 2 of the remote controller 1 will be described with reference to FIGS.

  As shown in FIG. 7, as setting contents transmitted from the indoor unit 20, a thermopile infrared sensor 25 provided in the indoor unit 20 determines a person based on a temperature difference between a room temperature and a human body temperature. In the mode in which air conditioning is performed in the center of the room where the room is located, the display unit 2 of the remote controller 1 can display “Driving according to the number of people.

  Further, as shown in FIG. 8, as a setting content transmitted from the indoor unit 20, in the mode in which the thermopile infrared sensor 25 detects the temperature unevenness in the room and air-conditions the entire room without any unevenness, the display of the remote controller 1 is displayed. In part 2, it can be displayed that “if the entire room is air-conditioned, it is about 5.0 yen per hour”.

  In addition, as shown in FIG. 9, regardless of the setting content transmitted from the indoor unit 20, the thermopile infrared sensor 25 is used to air-condition the center of the room where the person is located or to air-condition the entire room without unevenness. The predicted value of the electricity bill per unit time in the mode is displayed. In addition, by providing a selection button 9 that can select which mode to start the operation and start the operation, an expected value of the future electricity bill can be known in the user's favorite operation mode. .

  Here, it can be easily understood by changing the thickness of the frame line which is selected. In the example of FIG. 9, a mode for performing air conditioning at the center of the position of a room where a person is present is selected.

  In addition, when the movement amount can be detected by the dedicated button 11 or the movement amount detection sensor 14 while the operation is stopped, the two-way communication is performed from the transmission unit 12 of the remote controller 1 to the reception unit 22 of the indoor unit 20, and the indoor unit 20 The temperature in the room is detected by a temperature sensor provided in the, and the detection result is transmitted from the transmission unit 23 of the indoor unit 20 to the reception unit 13 of the remote controller 1.

  As shown in FIG. 10, the remote controller 1 expresses the received current room temperature information and the set temperature currently set by the remote controller 1 in an easy-to-understand manner with numerical values and pictures, and predicts the electricity cost per unit time (fuel consumption). At the same time, it is displayed on the display unit 2.

  The user looks at the predicted value (fuel consumption) of the electricity bill per unit time displayed on the remote controller 1 and, for example, when changing the set temperature, presses the temperature adjustment button 4 to change the setting (S24).

  The remote controller 1 is based on a comparison value between the accumulated power amount α per unit time stored in the remote control microcomputer, the setting information average value β, and the setting content whose setting has been changed. Calculate the predicted value of the integrated power consumption per unit time, or the predicted value of the electricity bill per unit time (fuel consumption) converted from the integrated power amount, or the predicted value of CO2 emissions per unit time by the remote control microcomputer ( Predicted) (S22) and displayed on the display unit 2 (S23). In FIG. 6, the predicted value of the CO2 emission amount per unit time is not shown.

  If the predicted value (fuel consumption) of the electricity bill per unit time is acceptable to the user, the setting condition change is terminated (the setting condition is not changed in S24). For example, if the cooling operation is to be started, the remote control 1 The air conditioner starts operation by transmitting a cooling operation start signal from the transmission unit 12 to the indoor unit 20 by the operation on / off button 3 or the cooling button 6 which is the operation mode.

  If the user has not changed the setting from the previous operation setting to the current operation (the setting condition is not changed in S24), the air conditioner is set with various settings when the air conditioner was operating last time. Is operated (the various settings here indicate temperature, humidity, wind speed, wind direction, etc.). In S21, the start button of the cooling operation is transmitted by the operation on / off button 3 of the remote control 1 or the cooling button 6 which is the operation mode without the dedicated button 11 of the remote control 1 being pressed or the movement of the remote control 1 being detected. The same applies to the case where the air conditioner starts operation by transmitting to the indoor unit 20.

  When the reception unit 22 of the indoor unit 20 receives the operation start signal transmitted from the transmission unit 12 of the remote controller 1, the indoor unit control device turns on the power and starts the operation of the air conditioner (current operation). (S13).

  Subsequently, at the start of operation, the indoor unit control device transmits the previous integrated power amount α per unit time stored in the indoor microcomputer and the setting information average value β during the previous operation by the transmission unit 23 of the indoor unit. (S14), the receiver 13 of the remote controller 1 receives the data and stores it in a remote controller microcomputer (not shown) (S26) (communication Y). In this way, by performing bidirectional communication between the remote controller 1 and the indoor unit 20 a plurality of times, the previous transmission data can be used even when the bidirectional communication fails, and the predicted value of the electricity cost per unit time ( It is possible to avoid the fact that (fuel consumption) cannot be displayed.

  The information received from the remote controller 1 indicates that the indoor microcomputer uses, for example, the cooling mode and the data on the difference between the room temperature and the set temperature using the cable 40 to the outdoor unit 30 (the outdoor microcomputer built in the control device 31). Send to.

  Operation at the optimal frequency (frequency that allows the room temperature to quickly approach the set temperature in the cooling mode) in response to a command from the outdoor microcomputer that has received the information on the indoor unit 20 (cooling mode and the difference between the room temperature and the set temperature) The compressor 32 performs.

  Thereby, the air conditioner performs the cooling operation while changing the frequency of the compressor 32 so that the room temperature becomes the set temperature.

  The indoor microcomputer of the indoor unit 20 communicates with the outdoor microcomputer and outputs a current value output from a circuit (not shown) that detects a current during operation of the air conditioner and a device (compressor) including the compressor 32. The integrated electric energy is calculated from the power factor value determined in advance from the operation characteristics (blower rotation speed, current value, etc.) of the air conditioner other than the machine 32 and the operating characteristics of the air blower.

  Further, the integrated electric energy A per unit time is calculated from the calculated integrated electric energy and the accumulated operation time from the start of operation, and stored in the indoor microcomputer (S15).

  In addition, the electricity bill is obtained by the product of the calculated integrated electric energy A per unit time and the electricity bill unit price (yen / kWh).

  Here, the unit price of electricity can be arbitrarily set to the amount of money with the remote controller 1, and the amount of money according to the user's area can be entered, and the value is closer to the value of the electricity bill in the environment used by the user. be able to.

  Further, the indoor microcomputer stores the average value B of the setting contents (temperature, humidity, etc.) set within the period from the start of operation to the stop (S15). In S15, the integrated power amount per unit time and the setting information average value during operation are calculated and stored.

  Then, the user presses the operation on / off button 3 of the remote controller 1 to transmit an operation stop signal from the transmitter 12 of the remote controller 1 to the indoor unit 20 (S27).

  When the receiving unit 22 of the indoor unit 20 receives the operation stop signal from the remote controller 1 (S16), the indoor microcomputer of the indoor unit 20 stores the average value of the stored setting contents before stopping the air conditioner. B and the integrated electric energy A per unit time are transmitted by the transmission unit 23 of the indoor unit (S17), received by the reception unit 13 of the remote controller 1, and stored in the remote control microcomputer (S28) (communication Z). . S17 is a transmission unit that transmits the integrated power amount per unit time and the setting information average value during operation to the remote control device.

  Here, if the communication Z at the time of operation stop is successfully acquired and the average value B of the setting content and the integrated electric energy A per unit time can be acquired, the information acquired by the communication Y at the time of operation is overwritten and stored. Is done.

  As an opportunity to display the predicted value (fuel consumption) of the electricity cost per unit time on the display unit 2, the electricity cost is predicted when the dedicated button 11 of the remote controller 1 is pressed or when the movement of the remote controller 1 is detected. By displaying the value (fuel consumption) on the display unit 2 for a certain period of time, it is possible to suppress the battery life of the remote controller 1 from being shortened.

  By using the movement amount detection sensor 14 that can detect the movement amount of the remote controller 1, when the user picks up the remote controller 1, the estimated value of the integrated electric energy per unit time when driving with the set contents Or, by calculating the predicted value of electricity cost per unit time (fuel consumption) or the estimated value of CO2 emission amount per unit time converted from the integrated power amount, and displaying it on the display unit 2 The predicted value (fuel consumption) of the electricity bill can be easily confirmed.

  In addition, by providing the movement amount detection sensor 14, when it is picked up, it is displayed, and when no movement is detected for a certain period of time, the display content is erased, and the battery life of the remote control 1 is prevented from being shortened. can do.

  As described above, by displaying the predicted value (fuel consumption) of the electricity bill per unit time with the contents set in the remote controller 1 before starting operation, the set temperature is lowered more than necessary (during cooling). Suppress non-energy-saving behavior and promote user energy-saving behavior. In addition to predicting the electricity bill per unit time (fuel consumption), by showing the current temperature and the set temperature that has been set before driving, if this level is around, let's refrain from using the air conditioner. Alternatively, the user's energy-saving behavior to increase the set temperature (during cooling) can be promoted.

  Moreover, although the content by the difference of room temperature and preset temperature was demonstrated, the sensory temperature calculated from the indoor temperature sensor, the humidity sensor, and the thermopile infrared sensor 25 as information sent from the indoor unit 20, and the sensory temperature set with the remote control 1 By expressing numerically and numerically in an easy-to-understand manner, it is possible to appeal at the temperature felt by the user, and the same effect can be obtained. Here, the sensory temperature calculation unit calculates the sensory temperature from the indoor temperature sensor, the humidity sensor, and the thermopile infrared sensor 25.

  Further, visibility is improved by displaying on the remote controller 1 at hand instead of the display of the indoor unit 20 main body, and when the movement amount of the remote controller 1 is detected by the movement amount detection sensor 14, the predicted value of the electricity bill per unit time By displaying (fuel consumption), it is possible to display the predicted value of the electricity bill per unit time (fuel consumption) on the display unit 2 of the remote controller 1 without the user being conscious of it, and to predict the electricity bill per unit time The value (fuel consumption) can be confirmed, and the user's energy-saving behavior can be promoted. In addition to displaying the predicted value of electricity cost per unit time (fuel consumption) with the movement amount detection sensor 14, if there is no movement for a certain period of time, the display is turned off to extend the battery life of the remote control. Can do.

  Further, as shown in FIG. 6, the bidirectional communication between the remote controller 1 and the indoor unit 20 is performed not only in the communication X when the operation is stopped, but also in the bidirectional communication Y between the remote controller 1 and the indoor unit 20 at the start of the next operation. The same data as the communication X is transmitted with this information.

  In this way, by performing bidirectional communication between the remote controller 1 and the indoor unit 20 a plurality of times, the previous transmission data can be used even when the bidirectional communication fails, and the predicted value of the electricity cost per unit time ( It is possible to avoid the fact that (fuel consumption) cannot be displayed.

  Here, communication is performed twice before and after driving. However, the present invention is not limited to this, and when a signal is transmitted from the remote controller 1 during a series of driving, information is exchanged by bidirectional communication multiple times. However, the same effect can be obtained.

  The accumulated power per unit time stored in the indoor microcomputer and the setting information average value during operation, and the accumulated power per unit time stored in the remote control microcomputer and the average value of the setting contents are By storing and calculating a predicted value in each mode for each heating / dehumidifying mode, it is possible to avoid displaying the difference in the electric energy depending on the operation mode.

  Although the infrared LED is used as the bidirectional communication means, the bidirectional communication using wireless communication eliminates the directivity between the indoor unit 20 and the remote controller 1 and reduces the probability of transmission failure. An effect is obtained.

  FIG. 11 shows the first embodiment and is a flowchart showing another example of the operation of the indoor control device and the remote control device. In the example of FIG. 6, when the air conditioner is stopped, the remote controller 1 displays the electricity cost (fuel consumption) per unit time in order to extend the battery life, or when the dedicated button 11 of the remote controller 1 is pressed, or the remote controller 1 Although an example of displaying on the display unit 2 when the movement of the air conditioner is detected has been described, the electricity cost per unit time (fuel consumption) is always displayed on the display unit 2 of the remote controller 1 while the air conditioner is stopped. Good.

  In the flowchart shown in FIG. 11, since the electricity bill (fuel consumption) per unit time is always displayed on the display unit 2 of the remote controller 1 while the air conditioner is stopped, there is no S21 in FIG. 6. The other contents are the same.

  As in FIG. 7, after the operation of the air conditioner is stopped, the accumulated power amount A per unit time, the average value B of the setting contents, and the settings set by the remote controller 1 before the operation start are stored in the remote control microcomputer. From the comparison value with the content, the predicted value of the integrated electric energy per unit time when the operation is started with the setting content, or the predicted value of the electricity bill per unit time (fuel consumption) converted from the integrated electric energy, or An expected value of the CO2 emission amount per unit time is calculated by the remote control microcomputer and displayed on the display unit 2.

  When the communication Z between the indoor unit 20 and the remote controller 1 fails when the operation is stopped, the average value α of the setting contents at the previous operation received from the indoor unit 20 by the communication Y at the start time and the integration per unit time Unit time converted from the predicted value of the integrated power amount per unit time when the operation is started in the setting status from the setting content set on the remote control 1 before starting operation and the amount of power β, or the integrated power amount A predicted value (fuel consumption) of the per capita electricity bill or a predicted value of the CO2 emission amount per unit time is calculated by the remote control microcomputer and displayed on the display unit 2.

  Moreover, in addition to the room temperature and humidity, the thermopile infrared sensor 25 is used to calculate the sensory temperature, and the case of performing human-centered control and the case of performing control of the entire room has been described. Similarly, in an air conditioner controlled by room temperature / humidity, the estimated value of the integrated electric energy per unit time before the start of operation, or the predicted value of the electricity cost per unit time converted from the integrated electric energy (fuel consumption) ), Or when the expected value of CO2 emission per unit time is calculated and displayed on the display unit, the same effect can be obtained.
