Изобретение относитс к области холодильной техники.This invention relates to the field of refrigeration.
Известны регенеративные теплообменники дл каскадных холодильных машин с промежуточным теплоносителем, измен ющим cBoe агрегатное состо ние, содержащие теплообменные поверхности дл протекающих сред 1. Недостатком указанных теплообменников вл етс то, что они не предотвращают нагрев жидкого хладатеита, отсасываемыми из камеры теплыми ларами в период луска мащины .Regenerative heat exchangers are known for cascade chillers with an intermediate coolant that changes the cBoe state of aggregation and contain heat exchange surfaces for flowing media 1. The disadvantage of these heat exchangers is that they do not prevent the liquid coolant from being heated by suction from the chamber during heating of the mashina. .
Целью изобретени вл етс повышение термодинамической эффективности каскадной холодильной мащины в пусковом периоде. Это достигаетс тем, что кажда теплообменна поверхность заключена в автономные кожухи , соединенные по крайней мере с помощью одного трубопровода из нетеплопроводиого материала.The aim of the invention is to increase the thermodynamic efficiency of the cascade cooling mash during the start-up period. This is achieved in that each heat exchange surface is enclosed in autonomous housings connected by at least one conduit of non-heat conducting material.
На чертеже схематично изображен описываемый теплообменник.The drawing schematically shows the described heat exchanger.
Теплообменна поверхность 1 дл отсасываемых паров хладагента размещена в кожухе 2, а теплообменна поверхность 3 дл жидкото хладагента помещена в кожухе 4. Кожухи 2 и 4 соединены один с другим трубопроводом 5 из нетеплопроводного материала.The heat exchange surface 1 for the suction of the refrigerant vapor is placed in the casing 2, and the heat exchange surface 3 for the liquid refrigerant is placed in the casing 4. The housings 2 and 4 are connected to one other pipe 5 of non-conductive material.
В кожухе 4 находитс жидкий промежуточный теплоноситель Q, измен ющий в процессе теплообмена между жидким хладагентом и его парами :вое агрегатное состо ние. Такое введение теплообменника в схему каскадной холодильной машины позвол ет значительно сократить ее пусковой период и экономить электроэнергию дл работы компрессоров нижнего и верхнего каскадов машины.In the casing 4 there is a liquid intermediate heat carrier Q, which changes during the heat exchange between the liquid refrigerant and its vapors: a new state of aggregation. Such an introduction of the heat exchanger into the cascade chiller circuit significantly reduces its start-up period and saves energy for the operation of compressors of the lower and upper stages of the machine.
