摘要： PROBLEM TO BE SOLVED: To air-condition the whole passenger room area even if one unit among outdoor machines runs into trouble by providing two or more outdoor machines arranged on a floor of a moving body and plural indoor machines arranged in a ceiling part of the moving body, and connecting the respective outdoor machines in order to refrigerating cycles of respective systems of the whole indoor machines. SOLUTION: Indoor machines 7 of 12 units are arranged on the ceiling of a passenger room 2 of a train, and a single indoor machine 8 is respectively arranged on the ceiling of entrances 3 and 4, and a refrigerant delivered from refrigerant compressors built in outdoor machines 5 and 6 arranged in the entrance 3, is flowed in the whole indoor machines of 12 units through a main pipe 9 of refrigerant piping and a branch pipe 10 of refrigerant piping. The respective indoor machines 7 and 8 are formed as a structure that respective refrigerants delivered from the outdoor machine 5 and the outdoor machine 6 return to an evaporator without being mixed together. Therefore, even if one unit among the outdoor machines 5 and 6 runs into trouble, since the refrigerant delivered from another one unit flows in the whole outdoor machines 7 and 8 of 12 units, air-conditioning can be continued.

摘要： PROBLEM TO BE SOLVED: To accurately bring the indoor temperature into coincidence with a set temperature by collating the control conditions retrieved by first and second retrieving means with a predetermined control rule, and deciding the change amount of heating capacity in a heater. SOLUTION: When a set temperature Ts is set (ST1 to 2), a temperature change rate ΔTr is calculated (ST3, 4), the present indoor temperature Ta is compared with the temperature Ts, and a temperature deviation amount ΔTs is calculated (ST5). Then, a control condition retrieving unit 13 retrieves the control condition having the highest adaptability with the change rate ΔTs as the input variable of the temperature change rate membership function (ST6). Thereafter, a control condition retrieving unit 14 retrieves the control condition having the highest adaptability with the amount ΔTs as the input variable of the temperature deviation amount membership function (ST7). When a change amount deciding unit 21 collates the control condition with a control rule to decide the change amount P of cooling or heating capacity (ST8), a control output unit 22 controls so that the cooling or heating capacity is altered by the amount Pw (ST9).

摘要： PROBLEM TO BE SOLVED: To air-condition the whole passenger room area by the other one unit even if one unit among two air conditioners runs into trouble by providing an air-conditioning duct to supply conditioned air from the respective air conditioners to a passenger room by collecting it to a single system in the two air conditioners arranged in either one end part before and behind a moving body. SOLUTION: In a moving body 1 such as a train, two air conditioners 2R and 2L are arranged in either one end part before and behind the moving body by sandwiching a passage 7, and an air-conditioning duct 3 to supply conditioned air 6 blown off from these air conditioners 2R and 2L to a passenger room 1a, is arranged along a central ceiling surface of the moving body. That is, the conditioned air 6 blown off from the two air conditioners 2R and 2L is supplied over the total length of the passenger room 1a after it is collected to a single system by the air-conditioning duct 3. Therefore, even if one unit among the air conditioners 2R and 2L runs into trouble, since the conditioned air blown off from the other one unit can be supplied to the whole passenger room area, air-conditioning can be continued.

摘要： PROBLEM TO BE SOLVED: To provide size reduction in an AC/DC switch-over device so that it may be fitted under the floor of a vehicle or the like. SOLUTION: An AC terminal 3 and a DC terminal 4 are disposed in a roughly straight form with a common terminal 5 between, a movable contact 13 is formed by a linear conductor and held by the fixed contact 12 of the common terminal 5 so that it may conduct a linear movement along the longitudinal direction. Fixed contacts 11, 14 are fitted so that they may be electrically- connected to the AC terminal 3 at one end of the linear movement of the movable contact 13 and the DC terminal 4 at the other end. In other words, a space in a cross direction of the movable contact 13 is decreased and the size in the one-axis direction of this AC/DC switch-over device is suppressed from increasing. An operation lever 17 is fitted in a plane parallel to the linear movement surface of the movable contact 13 so that it may oscillate and is oscillated by an electromagnetic drive device 9 which includes cylindrical coils 33-36 and plungers 43-45, thus conducting AC/DC switching by making the movable contact 13 conduct the linear movement.

摘要： PROBLEM TO BE SOLVED: To provide an AC/DC switching circuit which can prevent a delay in no-voltage release of a DC voltage detecting relay and prevent a short circuit of a DC power supply even when a short-circuiting failure of a contractor occurs. SOLUTION: A contractor 11A of one circuit and one contact which turns ON in an AC section and OFF in a DC section is provided between the (+) side 6A of a DC output end of an auxiliary rectifier 6 and the (+) side of an input line of an auxiliary circuit 5, while a contractor 1B of one circuit and one contact which turns OFF in the AC section and ON in the DC section is provided between either 6B of AC input ends of the auxiliary rectifier 6 and a grounding device 8. Accordingly, it is unnecessary to use an AC-DC changeover switch being a specific device and the specifications of main circuit equipment can be standardized by the contractors. Even when the contractors fail to operate, no short circuit of a power supply takes place and no effect is produced on other electric cars. Since only necessary minimum rectifying elements are used for checking the reverse voltage of the auxiliary circuit, the power loss in the auxiliary rectifier can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a power running/regeneration switching circuit of an AC-DC dual system electric car which dispenses with a power running/ regeneration changeover switch and an AC-DC changeover switch which are specific devices having functions of AC ON and DC OFF/AC OFF and DC ON with two circuits and a plurality of contacts. SOLUTION: In an AC-DC dual system electric car which conducts AC power running/regeneration by a separate excitation type thyristor converter 6, a power running/regeneration switching circuit is constructed by using four contactors 11A, 11B, 11C and 11D each having only an ON/OFF function with one circuit and one contact, and a contactor 7A for AC-DC changeover is provided between the (-) side of a main-circuit DC input end and a grounding device. Thereby the contactors used for a main circuit can be standardized. Since the power running/regeneration switching circuit shares a part of the function of an AC-DC switching circuit, besides, circuitry can be simplified and this is advantageous to make the equipment small in size and light in weight.
