However, the display element 3 composed of the LED chips 17 held on the printed wiring board and the display element 4 composed of the LED chips held on the printed wiring board are each supported by separate support frames, and It may be attached to the body 2. In FIG. 3, the surface of the lid facing the display elements 3 and 4 is an opening, and a transparent plate is mounted in the opening with a member having a waterproof function such as a gasket interposed therebetween. . However, when the entire material forming the lid 2 is transparent, the numerical values displayed on the display element 3 and the display element 4 can be observed from the outside, so that it is necessary to provide an opening as shown in FIG. There is no.

  As the printed wiring board, any conventionally known board can be used, but it is preferable to use a membrane sheet using a polyester film as a support, because a thinner display element can be obtained.

  FIG. 4 is a schematic view of an LED numeric display element plate. An example is shown in which a seven-segment LED numeric display element using seven LED chips 17 to display a single-digit number is used as the LED numeric display element plate 18. The seven-segment LED is a combination of seven LED chips, and displays numbers from 0 to 9 by appropriately emitting light from each LED chip. An 8-segment LED including a decimal point may be used.

  In the above embodiment, there are two types of display elements, a display element that displays the cumulative total of the actual operating time of the compressor as a display element and a display element that displays the cumulative total of the time in which the operation of the compressor is controlled. When there is a control panel in the room as in the above, a display element for displaying the total time during which the control panel is on can be provided. Even in this case, it is preferable that the third display element can be observed from outside.

A printed matter 19 displaying information on which data from the display element 4 can be used is affixed. In this example, the data from the display element 3 for displaying the total of the actual operating time of the compressor is an OPERATION meter value (OP meter value), and the data from the display element 4 for displaying the total of the time when the operation of the compressor is controlled. Is the SAVE meter value. That is, the calculation formula for calculating the power consumption reduction rate is SAVE meter value ÷ (SAVE meter value + OP meter value). By substituting the data from the two display elements into this formula, the reduction rate of the power consumption obtained by using the power saving control device according to the present invention can be obtained.

  Further, by attaching the printed matter 19 to the inner surface of the lid 2, the printed matter has a structure that imparts weather resistance, and the printed matter is semi-permanently displayed without being stained or faded by rainwater or dust. Can be seen from outside. In addition, since the electronic component mounted printed circuit board 5 housed in the housing 1 is not directly visible from the outside, this is a preferable embodiment from the viewpoint of aesthetic appearance. As shown in FIG. 2, when the printed circuit board 5 has a structure in which the electronic component-mounted printed circuit board 5 is housed in a state where it is suspended by screws on the pedestal 7 having a hollow portion, the printed matter 19 has a hollow portion. It can also be attached to the gantry 7 formed.

As information that can utilize data from the display element that displays the cumulative total of the actual operating time of the compressor and the display element that displays the cumulative total of the time that the compressor has been operated, in addition to the calculation formula for calculating the reduction rate, There are a formula for calculating the amount of reduction, a conversion formula for calculating the carbon dioxide emission, and the like. The formula for calculating the amount of reduction is SAVE meter value × compressor capacity × 1.5 (coefficient) × unit price. As a conversion formula for calculating the carbon dioxide emission, for example, an OP meter value (time: h) × rated power consumption (kW) × carbon dioxide emission coefficient (kg / kW · h) = CO ₂ amount (kg) Notation. As the carbon dioxide emission coefficient, for example, a numerical value of 0.357 (kg / kW · h) can be used.

  Next, an example of using the power saving control device according to the present invention will be described. The power saving control device according to the present invention was installed in an outdoor unit of a commercial air conditioner (compressor capacity 5.5 kW). The installation work was completed in a very short time due to the high degree of freedom in arranging the terminal blocks. It was established on June 24, 2003, and surveyed on July 7, 2003. The display element for displaying the total operation time of the compressor displayed 24.3 hours, and the display element for displaying the total time when the operation of the compressor was controlled displayed 11.9 hours. From these numerical values, it can be easily calculated that the reduction rate is 32.9% (11.9 ÷ (11.9 + 24.3) = 0.329). In addition, the reduction amount can be easily calculated as 1473 yen (11.9 × 5.5 × 1.5 × 15 = 1472.6, where the unit charge is 15 yen per kW). Furthermore, the carbon dioxide emission can be easily calculated as 47.7 kg (24.3 × 5.5 × 0.357 = 47.7).

In addition, since the power saving control device according to the present invention is provided with waterproof and dustproof measures of IP-65 protection grade, there is no influence by intrusion of rainwater or dust.
