Abstract

PURPOSE:To enable operation of an air-conditioner or a general home-use product to be carried out within a capability of an excessive current protection device even if an electrical current is increased as the air conditioner or the general home-use electrical appliances by a method wherein a load current flowing in a dwelling building is detected and an electrical current of the air- conditioner is controlled in response to the state of the load current. CONSTITUTION:CT circuits 7a to 7d always monitor an electrical current flowing in a commercial power supply line and perform a controlling operation in response to the operating states of air-conditioners 3a to 3c and general home-use electrical appliances 18a to 18c. As an electrical current value flowing in a main power supply line exceeds an electrical current value defined by the first electrical current setting circuit 11, a capability is metered in sequence from the air-conditioner of which preference order is set low and an increasing of the electrical current value is restricted. As the electrical current value flowing in a branch power supply line exceeds an electrical current value defined by the second electrical current setting circuit 12, the air-conditioner connected to the branch line has a metered capability and then an increasing of the electrical current is restricted.

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a control device for a plurality of air conditioners and a control method thereof. There is a growing trend that we are nearing the dawn of a new media era in which a single central control device will control multiple controlled devices. On the other hand, on the power supply side of the home, there is a growing need to strengthen the power supply equipment in order to cope with the peak load due to the increase in the load of air conditioners and non-air conditioners. In reality, due to differences in load operation rate and load usage characteristics for power supply equipment,
Problems that the invention aims to solve even if a situation that inhibits the benefits of the consumer occurs, such as when an overcurrent protection device is activated.When electrical appliances other than the air conditioner are being used at full capacity in a general household. If the compressor is started under severe air conditioning conditions, or if an air conditioner equipped with a capacity conversion device is operated at its maximum capacity, the current flowing through the overcurrent protection device may exceed its allowable amount and turn OFF. The method of the present invention solves the above-mentioned conventional problems, regardless of the magnitude of the current value of equipment other than air conditioners. The purpose is to prevent excessive currents caused by the operation of air conditioners and electric appliances other than air conditioners.

When the current value flowing through the main power supply line exceeds the current value determined by the first current setting circuit, the capacity of the air conditioners set lower in priority is sequentially reduced to suppress the increase in current. When the flowing current value exceeds the current value determined by the second current setting circuit, the capacity of the air conditioner connected to that branch line is throttled and the increase in current is suppressed. It is necessary to know which system on the commercial power supply line the conditioner is connected to. Therefore, in the present invention, the air conditioners 3a to 3c are sequentially operated with 1 silver, resulting in an increase in the output of the CT circuits 7a to 7d. It determines the system of the power line connected to it.
