Each electricity bill is transmitted from the center server 7. The electricity bill display unit is in increments of 10 yen, and when the electricity bill calculation accuracy is improved, the electricity bill can be displayed in increments of 1 yen. The electricity bill calculation method will be described later. The electricity bill can be set not only from the portable terminal 9 but also from an air conditioner remote control or a home PC.

Next, an electricity cost calculation method in the center server 7 will be described. The current value during the air conditioner operation is transmitted at a communication interval of a certain time. From the current value transmitted as shown in FIG. 6, the formula for calculating the integrated power is as shown in equation (1).
ΣP = (ΣXi × Ii × (100 or 200) × 0.9) / 3600 (1)
ΣP: Integrated power (Wh)
ΣXi: Integration of time (s) Ii: Current (A)
100 or 200: power supply voltage (V)
0.9: Power factor (%)
The accumulated power is calculated by multiplying the time value Xi from the sent current value Ii to the next transmission timing (Ii + 1) by the current value Ii, the air conditioner power supply voltage, and the power factor.
The power supply voltage of the air conditioner is set to 100 V or 200 V in advance from the PC 5 or the portable terminal 9 and transmitted to the center server 7. The power factor is set to a value assumed in advance in the center server 7.
Next, the electricity cost for the air conditioner is calculated by multiplying the calculated accumulated power by the electricity cost per unit accumulated power. The electricity cost per unit integrated power can be set in advance in the center server 7 or set for each electric power company with which the user has a contract, and a value closer to the actual electricity cost can be calculated. One example is shown in the following equation (2).
Y = ΣP × 22 × 0.001 (2)
Y: Electricity bill (yen)
ΣP: Integrated power (Wh)
22: Example of price per unit kWh (yen / kWh)

  Using the basic concept of the above-described electricity bill calculation method, the electricity bill per hour, the electricity bill per day, or the electricity bill per month is calculated. In addition, although the resolution of the calculation of the electricity bill is 10 yen unit, it may be 1 yen unit or 100 yen unit.

Mail A is the day when C1 value is reached, Mail B is the day when C2 value is reached, and Mail C is the user's mobile phone when C3 value is reached. To send to. That is, when the electricity bill for one month calculated as shown in FIG. 7 exceeds the electricity bill set by the user (C3 value in FIG. 7), the center server sends the set electricity bill to the mobile terminal. An e-mail notifying that the above has been exceeded is sent (mail C). Also, in order to notify the progress of the set electricity bill, it exceeded a certain fixed value such as half of the set electricity bill (C1 value in FIG. 7) or 3/4 (C2 value in FIG. 7). Even in this case, a notification mail may be transmitted to each (mail B, A). FIG. 8 shows an example (mail A) displayed on the display screen 10 of the portable terminal 9 when the set electricity bill exceeds half, and FIG. 9 shows the display screen of the portable terminal 9 when the set electricity bill is exceeded. An example (email C) of 10 is shown, and the e-mail information can improve the energy saving awareness of the air conditioner user. In addition, when the set electricity bill is exceeded, a notification may be displayed on the home PC 5 or a remote controller of the air conditioner (not shown in FIG. 1) or on a display unit provided in the air conditioner body, and the same effect is obtained. can get. Users of air conditioners who have received notification information through these emails can change the set temperature or set humidity for the air conditioner's air conditioning, or change the setting of the daily operating time to make energy saving operation possible. . For example, by increasing the set temperature during cooling operation and lowering the set temperature during heating operation to reduce the air conditioning load, power consumption can be suppressed and energy saving can be achieved.

  Next, the electricity bill monitor in the home PC 5 will be described. As shown in the home PC initial screen of FIG. 10, after selecting the electricity bill display input section 21 on the PC display screen 20, the year and month for displaying the electricity bill are displayed from the year / month input section 22 as shown in FIG. The center server 7 is inquired by selecting and clicking the display input unit 23. The center server 7 sends the electricity bill for the year requested by the PC 5 to the PC.

  FIG. 12 shows an example of displaying the electricity bill transmitted from the center server. A graph displaying detailed data as shown in FIG. 12B appears in the graph display section 24 of the PC display screen 20. In FIG. 12 (b), the horizontal axis represents the day, the left side of the vertical axis represents the daily electricity bill (yen), the right side of the vertical axis represents the accumulated electricity bill and the set electricity bill (yen), and the bar graph represents each day. As an example of the electricity bill and the circled line graph, a line is drawn to the level of 2000 yen as an example of the accumulated electricity bill and the set electricity bill. In this way, the electricity bill is displayed as a graph or a numerical value for the electricity bill for each day, the accumulated electricity bill for one month, and the electricity bill that may be spent for one month set by the user with a portable terminal or the like. . FIG. 13 shows an example displayed as a numerical table instead of a graph. It is displayed on the numerical display unit 26 of the PC display screen 20 as numerical data as shown in FIG. In this way, since the accumulated electricity bill for each day can be displayed by the home PC 5, it is possible to predict the future transition and preventive measures can be taken in advance. On the PC5 screen, if the user sets half of the set electricity bill earlier than the 15th day of half a month, change the set temperature or set humidity (change the set temperature during cooling). Information, such as increasing the set humidity during dehumidification, decreasing the set temperature during heating), or shortening the operation time, and further providing one-point information (such as closing the curtain) to save energy By displaying, energy-saving operation can be promoted to the user.

  Furthermore, since the home PC 5 is communicably connected to the air conditioner 1 via the access point 4, if the accumulated electricity bill exceeds a predetermined value of the set electricity bill, the operation setting condition of the air conditioner from the PC It is also possible to promote energy-saving operation by transmitting a command to change.
