The body 2 is fitted, and screws 12 are passed through the screw holes 10 at the four corners of the lid 2 and the screw holes 11 at the four corners of the housing 1, respectively. It is fixed to an outdoor unit or the like (not shown) of a power consuming device equipped with a compressor such as equipment, refrigeration equipment, and cooling equipment. Alternatively, the housing 1 is first fixed to an outdoor unit or the like of the power consuming device with a screw or the like different from the screw 12, and after the lid 2 is fitted, the lid 2 and the housing 1 are fixed with the screw 12. You can also.

  The main materials constituting the housing 1 include engineering plastics such as polyethylene (PE), polystyrene (PS), ABS resin, and other general-purpose plastics, polyamide (PA), polycarbonate (PC), polybutylene terephthalate (PBT), and polyacetal. Plastics. These may be transparent or opaque by mixing a pigment or the like. Further, a metal such as aluminum and iron may be used. On the other hand, the cover 2 has a transparent surface 21 facing at least two indicators. Usually, since the lid is injection-molded, the entire lid 2 is preferably made of a transparent plastic, such as an acrylic resin or a polycarbonate resin.

  The lid 2 can be formed of a metal such as aluminum. In this case, the display 8 for displaying the total of the actual operation time of the compressor and the display 7 for displaying the total of the time in which the operation of the compressor is controlled are observable, for example, opposed to these two displays. It is preferable that a window is provided on the surface of the lid 2 or a notch is provided at the location, and the display is projected outside from the notch.

  FIG. 3 is a perspective view of the lid 2 viewed from the inside. The lid 2 has a protruding end 14 formed on the inner peripheral surface thereof so as to fit into the housing 1, and a gasket 13 is provided in an annular groove (not shown) formed along the protruding end 14.

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

  FIG. 4 is a perspective view of the power saving control device in which printed matter is attached to the inner surface of the transparent portion of the lid 2. FIG. 4 is an example in which the entire lid 2 is formed of a transparent plastic, and a display for displaying the cumulative total of the actual operation time of the compressor and a time for controlling the operation of the compressor are provided on the inner side surface of the lid 2. A printed matter 20 displaying information that can utilize data from a display device that displays the total number of items is attached. In this example, the data from the display that displays the total of the actual operating time of the compressor is an OP meter value, and the data from the display that displays the total of the time during which 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 displays 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 20 to the inner surface of the side surface of the lid 2, the printed matter has a structure that imparts weather resistance, and the printed matter is displayed semi-permanently without being stained or faded by rainwater or dust. This is a preferable embodiment not only from the viewpoint of aesthetic appearance, since the circuit board housed inside the housing 1 is not directly visible from the outside as well as the information can be viewed from the outside. A printed material 30 on which the product name of the power saving control device according to the present invention and safety precautions are printed is affixed on the upper surface of the gantry 3 having the hollow portion, and can be read through the upper surface 21 of the lid 2. Can be done.

As information that can utilize data from the display that displays the cumulative total of the actual operating time of the compressor and the display 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 for displaying the total running time of the compressor displayed 24.3 hours, and the display for displaying the total time for controlling the operation of the compressor 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.
