摘要： PURPOSE:To suppress interruption of a breaker due to overccurent, to allow a small current contract, and to lighten the load on an appliance due to turn ON/OFF of power while enhancing the operability. CONSTITUTION:An adapter 2 is connected between an appliance 6c which can be interrupted with an overcurrent and a receptacle. When the detected current exceeds a contract current limit, the breaker 1 interrupts the adapter and if the contract current exceeds the limit even after interruption of all adapters, the breaker interrupts. The breaker makes a decision whether somebody is present based on the operating state of alliance and relaxes the conditions of automatic interruption control set for safety if some person is recognized. The alliances are interrupted only partially when the current exceeds the limit and if the contract current exceeds it continuously, the breaker functions to interrupt power in safety. Furthermore, since the conditions of automatic interruption control for safety are relaxed, long time operation is allowed to enhance the operability.

摘要： PURPOSE:To suppress interruption of a breaker due to overcurrent, to allow a small current contract, and to lighten the load on an appliance due to turn ON/OFF of power. CONSTITUTION:An adapter 2 is connected between an appliance 6c which can be interrupted with an overcurrent and a receptacle, and a communication means is provided for a breaker 1. The breaker 1 stores the priority of interruption for the adaptor and when a detected current exceeds a contract current limit, the adapter is interrupted according to the priority. If the overcurrent is eliminated in the way of interruption, the adaptor is reset at that moment. If the current exceeds the limit even after interruption of all adapters, the breaker interrupts. Consequently, the appliances are interrupted only partially even if the current exceeds the limit and when the contract current exceeds continuously, the breaker functions to interrupt power in safety. Furthermore, various signals may be transmitted from the adapter to the breaker.

摘要： PURPOSE:To protect an electric appliance over-loading due to abrupt interruption of power thereto by interrupting power to preselected electric appliances when the total current exceeds a contact current limit. CONSTITUTION:Adapters 2 are provided for an air-conditioner 6c, a hair dryer 6d and a microwave oven 6e which do not cause serious trouble upon abrupt power interruption. When the total current exceeds a contact current limit, an interrupting mechanism built in the adapter 2 functions to interrupt power to the electric appliance connected with the adapter 2. If the total current does not drop below the contract current limit, a breaker 1 functions to interrupt power to all the systems. This system realizes efficient use of power without increasing the contract current limit while taking account of temporary increase of power.

摘要： PURPOSE:To avoid interruption by a breaker due to overcurrent, to allow a small current contract, and to prevent an accident of an appliance not turned OFF inadvertently. CONSTITUTION:An adapter 2 is connected between an appliance 6c which can be interrupted with an overcurrent and a receptacle. When a detected current exceeds a contract current limit, a breaker 1 interrupts the adapter current and if the contract current limit is exceeded even after interruption of all adapters, the breaker is interrupted. An allowable conduction time is set for the breaker or the adapter and it is interrupted when the working time of adapter exceeds the allowable time. Consequently, the appliances are interrupted only partially even if the contract current limit is exceeded and when the current exceeds the contract limit continuously, the breaker functions to interrupt power in safety. When the current flows longer than the allowable time, a decision is made that an appliance is not turned OFF inadvertently and power is interrupted automatically.

摘要： PURPOSE:To prevent a cooling capacity from being decreased and enable a stable operation of an air conditioner to be carried out by a method wherein a reduction in cooling capacity against an absorbing device caused by deterioration in aging or closed contamination at cooling fins is sensed in response to a variation of the number of rotation in an air-cooled fan then to inform a user of a clogged state in the cooling fins. CONSTITUTION:A controller 30 controls each of a blower fan 11, an air-cooled fan 17, a pump 23, a control valve 15 in a fuel supplying pipe 14, various valves V1 to V5 and each of alarm lamps 33 and 34 in response to various sensing signals produced from various sensors T1 to T7 arranged at an outdoor device and an output signal produced from a communication controller 31 connected to an indoor device 2. At this time, the controller 30 confirms that the rotation of the air-cooled fan is normal. In turn, it stores an appropriate temperature at an outlet of the absorbing device 20 which is predetermined in response to a surrounding air temperature, an outlet sensed temperature of the absorbing device and time-series variation data calculated in response to both these temperatures. When the variation data exceeds a specified value, a clogged state in the cooling fins in the absorbing device 20 is alarmed to a user.

摘要： PURPOSE:To obtain concentrated ratio of absorbent liquid and condensing temperature irrespective of a decrease in a cooling capacity and maintain a capacity of an absorber by increasing or decreased a quantity of heat to be supplied to a regenerator and a pumping capacity of a pump for sending dilute absorbent liquid in response to an increase or decrease in an air conditioning load. CONSTITUTION:An air conditioner has an outdoor unit 1 and an indoor unit 2. The outdoor unit evaporates refrigerant in an evaporator 10, absorbs the refrigerant vapor to absorbent liquid by an absorber 20, heats the dilute absorbent liquid by a regenerator 12 to generate refrigerant vapor and concentrated absorbent, and condenses the vapor by a condenser 16. After the air in a room is directly cooled by the evaporator 10, the cooled air is blown into the room to cool it. With such a structure, a controller 30 increases or decreases a quantity of heat to be supplied to the regenerator 12, i.e., pumping capacities of a valve 15 for regulating fuel gas to be supplied to a burner 13 and a pump 23 for pumping the dilute absorbent liquid in response to an increase or a decrease in air conditioning load.
