た。[Detailed Description of the Invention] Industrial Application Field This invention relates to a centralized control device for multiple air conditioners and a centralized control method thereof. There is a growing trend that the era of new media, in which multiple controlled devices are controlled by a single central control device, is nearing its end. The use of centralized control devices for air conditioners is increasing, and on the power supply side of homes (as well), power supply facilities are being strengthened to cope with the peak load associated with the addition of air conditioners and loads other than air conditioners. The reality is that power supply equipment has different circumstances due to differences in load availability and load usage characteristics.
Problems that the invention aims to solve even if a situation that harms the benefits of consumers occurs, such as when an overcurrent protection device is activated. When the compressor is started under heavy air conditioning conditions, when an air conditioner equipped with a frequency converter is started, the current flowing through the overcurrent protection device exceeds its allowable amount and the air conditioner turns off. This caused inconveniences in use, such as worsening the feeling of time and causing electrical appliances other than air conditioners to stop working.

Regardless of the magnitude of the current value other than the air conditioner, the overcurrent protection device can be turned off when the air conditioner starts operating or when an electrical appliance other than the air conditioner is turned on. Even if the purpose is to eliminate the operation, it may also be applied to areas where current limiters are used in addition to general overcurrent protection devices for main lines, based on the power supply method specific to the electric power company that supplies electricity. To explain the difference between the protective operation of a general overcurrent protection device and a current limiter, for example, in the operation of a general overcurrent protection device in a single-phase three-wire system, current is detected independently for each line, and one input When the current value specified by the overcurrent protection device in the relevant line is exceeded, overcurrent protection is activated.

If the current value flowing through the wiring of the house and detected by the CT circuit is smaller than the output of the first return current setting means, then the signal is transmitted to the air conditioner that outputs the simultaneous stop signal. A signal for returning to the original operating state is output to each air conditioner operating terminal 22 via the transmitting/receiving section 2, starting with the air conditioner with the highest operating priority. Terminal 22

The current value detected by the C7 circuit is within the range of the current value determined by the first suppression current setting means. The operation of the air conditioner that has been restarted is monitored for a certain period of time, and only when the current value again exceeds the current value determined by any one of the suppression current setting means 1 to 4, the low priority air conditioner is immediately restarted. A return current value for restarting the operation of the air conditioner in question while carrying out suppressed operation at a constant cycle in the truncated period may be switched to a value determined by a second return current setting means that is larger than the first return current value. As the recovery control method 2, the restarted operation of the air conditioner is monitored by the recovery current setting means for a certain period of time, and each time the current value specified by any of the suppression current setting means 1 to 4 is exceeded again within a certain period of time. It is also possible to switch to the return current value determined by the plurality of return current setting means 1a to na, which are increased in order from the current value determined by the first return current setting means.
Further, each output of the comparators 35 and 36 is read through the Cpul and detected by the C7 circuit 34. If the current value flowing through the wiring of the house is larger than the output of the third b suppression current setting means, the air conditioning A signal to stop the air conditioner is transmitted to each air conditioner operating terminal 22 via the signal transmitting/receiving section 2, and the current value flowing through the wiring of the house detected by the C7 circuit is the return current of the 1b. If the output is smaller than the output of the setting means, a signal is outputted to each air conditioner operating terminal via the signal transmitting/receiving unit 2 to the air conditioners that output the simultaneous stop signal to return to the original operating state. Note that the signal transmitting/receiving section 2 and the air conditioner operating terminal 22 are connected via transmission lines 3 and 4, so that the signals of the central control device side signal transmitting/receiving section 2 and the air conditioner operating terminal 22 are connected to each other via transmission lines 3 and 4. Even after the transmission and reception, the same operations are performed for the suppression currents 1b to 2b and the second return current setting means, and will be described in detail below. If the flowing current value is larger than the output of the second b suppressing current setting means, at least the compressor of the air conditioner is stopped, and the current value flowing through the wiring of the house detected by the C7 circuit is If the output is greater than the output of the suppression current setting means, the operating frequency will be reduced for air conditioners equipped with a frequency converter, and 41 for general-purpose air conditioners.

Also, as a second return control method, the operation of the air conditioner restarted by the return current setting means is monitored for a certain period of time, and the operation is again suppressed within a certain period of time. The 1b current value is increased in order from the current value determined by the 1b return current setting means each time the current value determined by any of the current setting means 1b to 3b is exceeded.
Switching to the return current value determined by the plurality of return current setting means b to nbb. In the formula, when a power line is drawn into a house, one line is the neutral line and the other two lines constitute two power supply lines, but each air conditioner connects to the above power supply line ( Next, we will discuss the suppression and recovery operation of the 200V input air conditioner. Therefore, the air conditioners are detected by the CT circuit 12, and according to each output of the comparison means 1, the operation priority setting means 15 is set between the air conditioners. 1.% according to the operation priority determined by It is necessary to follow the set value of either system Ll or L2, which causes the operation priority to be set in two systems.

果が得られも28 is a means for displaying the current (Ll and L2) flowing through the residential wiring for each wiring system; at least the measured current for each wiring system; or the average value of the wiring system currents consisting of the at least two systems; Display hand north
Alternatively, there is a means of displaying the current flowing through the residential wiring for each wiring system as a ratio (usage rate) to the allowable current setting value of the overcurrent protection device (Table 1). The current flowing through the handrail or residential wiring, which is displayed as a ratio [usage rate] to the allowable current of the overcurrent protection device, is the ratio [use rate] to the value obtained by further correcting the allowable current to the allowable current setting value of the overcurrent protection device. Reference numeral 41 denotes a switching section for current display contents, and the above-mentioned display contents are switched by the display switching means 41 and displayed on the current usage rate display section. The centralized control system for conditioners is used when multiple air conditioners or electrical appliances other than the air conditioners are in use, such as when the current flowing through the overcurrent protection device and current limiter exceeds the allowable amount. This solves the inconvenience of using the air conditioner, such as turning off the air conditioner, which worsens the feeling when using the air conditioner, and causes electrical appliances other than the air conditioner to stop working.The effects are described below. ) Clothes in which overcurrent has flowed through the overcurrent protection device Do not turn off the overcurrent protection device and current limiter 8. Do not simply stop the air conditioner, but perform suppressed operation according to the level of the overcurrent. The number of unnecessary stop operations of the air conditioner is reduced, and the deterioration of the feeling of the air conditioner is prevented.2) Overcurrent flows through the overcurrent protection device and current limiter. By performing the operation, unnecessary stoppage of electrical appliances other than the air conditioner can be prevented.3) By setting the model classification to determine whether or not the operating frequency converter is installed, it is possible to prevent overcurrent from flowing to the overcurrent protection device. 4) The return current is adjusted according to the current capacity of the air conditioner used in the home and the capacity of equipment other than the air conditioner. For example, the return operating current value of an air conditioner that has been put into suppressed operation can be freely set depending on domestic circumstances. 5) The suppressed current value can be freely varied within the allowable current range of the overcurrent protection device. In addition, the current usage rate and allowable current value can be displayed.Especially when performing energy-saving operation, the effect is incredible. % 6) In addition to general overcurrent protection devices, similar control is possible in locations where current limiters are installed, and the same effects as above can be obtained.
