摘要： PROBLEM TO BE SOLVED: To provide a vehicle air-conditioning control system capable of collecting state information of a vehicle air-conditioner, performing a precise survey/analysis of the air-conditioner in response to the state information and performing to control a remote vehicle air-conditioner in response to the result of the survey/analysis.
SOLUTION: A vehicle air-conditioning control device 1 installed at a vehicle of a train transmits data including an operating information of the installed air-conditioner and a position information about this vehicle. A control computer 300 accumulates data transmitted from the vehicle air-conditioning control device and processes it. With this operation, a precise survey/analysis for the air-conditioner can be carried out in reference to a rail-way line or a position and the like. With this operation, this invention resolves a problem found in the prior art train operation data collecting system in which the system only transmits an amount of power consumption consumed at an air-conditioner, motor and lightings from a running train through wire-less system regularly and the precise survey/analysis of the vehicle air-conditioner could not be performed.

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.
