Description

Известные способы получени  холода методом расширени  газа основаны на применении процессов дросселировани  и адиабатического расширени  с отдачей внешней работы.The known methods of obtaining cold by the method of expanding gas are based on the use of processes of choking and adiabatic expansion with the return of external work.

Предлагаетс  способ получени  холода, который не требует, в отличие от известных, расширительных машин, уменьшает таким образом стоимость производственного оборудовани  и  вл етс  более простым . Особенность предлагаемого способа заключаетс  в том, что сжатый в компрессоре газ пропускают через теплообменник-рекуператор в пр мом направлении с меньшей скоростью, чем в обратном.A method for producing cold is proposed, which does not require, in contrast to the known, expansion machines, thus reducing the cost of production equipment and is simpler. A feature of the proposed method is that the gas compressed in the compressor passes through the heat exchanger-heat exchanger in the forward direction at a slower rate than in the opposite direction.

На чертеже изображена схема, по сн юш.а  способ.The drawing shows a diagram, according to the method.

Сжатый газ, служаший хладоагентом,- подают компрессором / через холодильник 2 в 3-поточный теплообменник-рекуператор 3 в пр мом направлении по первой ветви а-б, где газ охлаждаетс  встречным потоком хладоагента. В теплообменнике-рекуператоре газ движетс  в пр мом направлении с небольшой скоростью. Охлажденный газ поступает во вторую обратную ветвь б-в теплообменника-рекуператора, где расшир етс  и нагреваетс , а его скорость Движени  повышаетс  до большой величины. Нагревание о.хлажденного газа происходит за счет тепла пр мого тока и от охлаждаемых в ветви г-д газа или жидкости.Compressed gas, which served as a refrigerant, is supplied by a compressor / through cooler 2 to a 3-way heat exchanger-heat exchanger 3 in the forward direction through the first branch ab, where the gas is cooled by a counter flow of refrigerant. In the heat exchanger-heat exchanger, the gas moves in a forward direction at a low speed. The cooled gas enters the second reverse branch b-in the heat exchanger-heat exchanger, where it expands and heats up, and its Motion speed rises to a large value. The heating of the cooled gas occurs due to the heat of the direct current and from the gas or liquid cooled in the g-d branch.

Кинетическа  энерги  хладоагента, выход щего из теплообменника-рекуператора из ветви б-в, гаситс  в холодильнике 4 вне теплообменника-рекуператора .The kinetic energy of the refrigerant leaving the heat exchanger-heat exchanger from the branch b-c is quenched in refrigerator 4 outside the heat exchanger-heat exchanger.

При высоких скорост х движени  полезна  холодопроизводительность единицы хладоагента может иметь большую величину. Например , если в качестве хладоагента вз ть водород и выпускать его из ветви б-в теплообменника- рекуператорд - в .. ртнке--в со скоростьюAt high speeds, the useful refrigerating capacity of a unit of refrigerant can be large. For example, if hydrogen is taken as a coolant and released from the branch b — in a heat exchanger — recuperator — in .. rtnke — in at a rate of

1300 м1сек (звукова  скорость движени  водорода при комнатной температуре ), то полезна  холодопроизводительность единицы хладоагепта составл ет 200 ккал1кг, в то как изотермический эффект дросселировани  водорода от 150 атм, с предварительным охлаждением; жидким азотом, равен 50-60 ккал/кг.1300 m1sec (sonic velocity of hydrogen at room temperature), then the cooling capacity of a unit of refrigerant is 200 kcal1kg, while the isothermal effect of hydrogen throttling is from 150 atm, with preliminary cooling; liquid nitrogen is equal to 50-60 kcal / kg.
