Electric power control apparatus

Abstract

An electric power control apparatus having an operation monitor unit for monitoring the operational state of an electric power device, an electric power control unit for shifting the device to a driving state of a low power consumption, and a timing control unit. The timing control unit comprises first means for introducing a control mode at every predetermined control cycle second means for maintaining a standby, in the control mode, until a predetermined time elapses after a shift of the device to a normal driving state third means for activating the electric power control unit if the device is in the normal driving state after that standby and for maintaining, if the device is in the low power consumption state after that standby, another standby until the device gets into the operating state, and then activating the electric power control unit after another predetermined time elapses communication means for performing a data communication with the exterior remote control means for performing the control based on a control data received from the exterior and data transmission means for transmitting the operation status to the exterior.

Description

technical field [0001] The present invention relates to a power control device for reducing power consumption of power equipment such as refrigerators and air conditioners. Background technique [0002] For example, electric power equipment such as refrigerators and air conditioners use a lot of power for their built-in compressors, so in order to reduce contract power supply and achieve power saving, so-called on-demand control is used. [0003] In the conventional on-demand processing control, the operation of the compressor is forced to stop for a preset time at regular intervals, regardless of the operating state of the air conditioner or the temperature of the room to be air-conditioned, that is, only A simple control method that shifts the machine to a low-power operation state for a certain period of time. [0004] However, in such a control method, the time when the compressor is forcibly stopped by the on-demand processing controller sometimes coincides with the ti...

Problems solved by technology

[0004] However, in such a control method, the time when the compressor is forcibly stopped by the on-demand processing controller sometimes coincides with the time when the air is supplied by the temperature adjustment mechanism of the machine itself. Looking forward to the power saving effect

[0005] In addition, the refrigerator or air conditioner repeatedly restarts and stops automatically through the temperature adjustment mechanism of the machine itself (see Figure 4 ), if the compressor is forcibly stopped without elapse of time from the restart, it will not be possible to smoothly reach the target ambient temperature for freezing, cooling, heating, etc.

In addition, if the start and stop are performed unilaterally according to the time schedule control, the distance of the refrigerant pipe arrangement, the oil return time, the temperature environment or pressure environment of the refrigerator, etc. will be ignored, and the life of the machine will be significantly shortened.

[0006] Furthermore, the compressor may be stopped before the restart time. In such a case, if the operation of the compressor is stopped for a long time, the judgment of the microcomputer installed in the refrigerator and air conditioner will be judged as an abnormality of the machine. There is also the fear of stopping the machine itself

[0007] In addition, when multiple devices are installed in one room, although the temperature of the compressor should be in the operating state, there is also the possibility that multiple devices will be in the air supply state at the same time, which will cause a problem that the temperature in the room will change rapidly.

[0008] In addition, since the operation adjustment conditions of the temperature adjustment mechanism of the refrigerator or the air conditioner, etc. are directly operated by operating the operation switch on the operation panel to perform changes, etc., it is impossible to perform changes, etc. at a remote place away from the operation panel. operation
