Description
: Изобретение относитс к автоматиче| скому регулированию холодильными уста| новками, например, в рефрижераторных: The invention relates to an automatic | regulation of refrigeration systems | newcomers, for example, in refrigerated
вагонах. wagons.
1 Цель изобретени - повышение эконо мичности и надежности.1 The purpose of the invention is to increase economic efficiency and reliability.
На фиг.1 показана схема рефрижераi торной секции; на фиг.2 (а, б, в, г) - времен; ные диаграммы работы холодильных Figure 1 shows a diagram of a refrigerator section; figure 2 (a, b, c, d) - times; refrigeration diagrams
; установок в разных вагонах.; installations in different cars.
Рефрижераторна секци состоит из дизельного вагона 1, двух рефрижераторных вагонов 4 и 8 (их количество может быть произвольным), дизель-генераторов 10, 11. j Холодильные камеры секций оснащены тер- модатчиками 2, 3, 6, 7. Рефрижераторный : вагон 4 оснащен холодильной установкой 5 : с компрессором 12, рефрижераторный ва- : гон 8 оснащен холодильной установкой 9 с компрессором 13. Мощность, потребл ема любым компрессором, составл ет N.The refrigerator section consists of diesel wagon 1, two refrigerator wagons 4 and 8 (their number can be arbitrary), diesel generators 10, 11. j The refrigeration chambers of the sections are equipped with temperature sensors 2, 3, 6, 7. Refrigerator: wagon 4 is equipped refrigeration unit 5: with compressor 12, refrigerated car: car 8 is equipped with refrigeration unit 9 with compressor 13. The power consumed by any compressor is N.
Способ управлени холодильной установкой осуществл ют следующим образом.The method for controlling the refrigeration unit is as follows.
Первый рефрижераторный вагон произвольно выбирают ведущим. Дополнительно задают диапазон температур t3-t2 во втором рефрежираторном вагоне 8, Причем (ta- t2)(ti-t2). Пусть, начина с момента времени т 1 (фиг.2) оба компрессора 12, 13 и дизель-генераторы 10, 11 отключены. При достижении заданной температуры 1з в момент времени г 2 во втором рефрижераторном вагоне 8 включают компрессор 13 и дизель-генератор 11 сигналом термодатчика 7. Загрузка дизель-генератора 11-IM. При достижении заданной температуры ti в рефрижераторном вагоне 4 в момент времени гз включают компрессор 12 и одновременно отключают компрессор 13 по сигналам термодатчика 2. Загрузка дизель-генератора 11-N. При достижении заданной температуры ti в рефрижераторном вагоне 8 в момент времени rs включают компрессор 13 и дизель-генератор 10 по сигналам термодатчика 6. При достижении заданной температуры т.2 в рефрижераторном вагоне 4 в момент времени т а по сигналам термодат00 СА)The first refrigerated wagon is arbitrarily selected as the lead. Additionally, the temperature range t3-t2 is set in the second refrigerated car 8, and (ta- t2) (ti-t2). Let, starting from time t 1 (figure 2), both compressors 12, 13 and diesel generators 10, 11 are turned off. Upon reaching the desired temperature 1z at time r 2 in the second refrigerator car 8, the compressor 13 and the diesel generator 11 are turned on by the signal of the temperature sensor 7. Loading of the 11-IM diesel generator. When the desired temperature ti is reached in the refrigerator car 4 at the time instant gz, the compressor 12 is turned on and the compressor 13 is simultaneously turned off by the signals of the temperature sensor 2. Loading of the 11-N diesel generator. Upon reaching the set temperature ti in the refrigerator car 8 at the time rs, turn on the compressor 13 and the diesel generator 10 according to the signals of the temperature sensor 6. When the set temperature t.2 in the refrigerator car 4 is reached at the time t and according to the signals of the temperature sensor 00 CA)

чика 2 выключают компрессор 12 и дизель- генератор 10. Загрузка дизель-генератора 11-N. При достижении температуры t2 в рефрижераторном вагоне 8 в момент времени г в отключают компрессор 13 и дизель-генератор 11 по сигналам термодатчика 6.Chika 2 turn off the compressor 12 and the diesel generator 10. Loading the diesel generator 11-N. When the temperature t2 is reached in the refrigerator car 8 at the time r, the compressor 13 and the diesel generator 11 are turned off by the signals of the temperature sensor 6.
Как видно из фиг,2,г.врем совместной работы дизель-генераторов, г Б- г е уменьшилось по сравнению с прототипом ТА- т в фиг.2,в и в пределе (при уменьшении диапазона температур) стремитс к нулю, т.е. охлаждение может выполн тьс одним дизель-генератором.As can be seen from FIG. 2, during the joint operation of diesel generators, Mr. Бе е has decreased compared to the prototype TAТ in FIG. 2, t and to the limit (with decreasing temperature range) tends to zero, t. e. cooling may be performed by a single diesel generator.
