Изобретение касаетс холодильной техники .The invention relates to refrigeration.
По основному авт. св. № 469865 известен способ производства холода в криогенных установках , преимущественно гелиевых, путем сжати газообразного хладагента, его охлаждени и адиабатического расширени в область влажного пара с использованием части, потока в детандере дл компенсации необратимых потерь, и адиабатического расширени оставшейс части потока до пограничной кривой жидкости в точке, соответствующей т пературе испарени хладагента.According to the main author. St. No. 469865 discloses a method for producing cold in cryogenic plants, preferably helium, by compressing the gaseous refrigerant, cooling it and adiabatic expansion to the wet steam region using part, flow in the expander to compensate for irreversible losses, and adiabatic expansion of the remaining part of the flow to the liquid boundary curve the point corresponding to the refrigerant evaporation temperature.
По предложенному способу часть потока , расшир емую до пограничной кривой жидкости, перед расширением охлаждают парами, образующимис при кипении хладагента .According to the proposed method, a part of the flow, expanded to the boundary curve of the liquid, is cooled before expansion by the vapors formed during the boiling of the refrigerant.
Это позвол ет повысить экономичность способа.This makes it possible to increase the efficiency of the method.
чертеже схематично изображена ус- дл осушествлепип способа. The drawing is a schematic representation of the method.
Хладагент (. гелий) нагнетают компрессором 1 частично к ,детандеру 2 и частично к детандеру 3, охлажда детандеры соответственно в теплообменнике 4 и в те5 плообменниках 5 и 6 обратным холодным I потоком, поступаюш.им из холодильной ка- меры 7 и отход щим от детандера 2. В теплообменнике 6 охлаждают только часть потока, расшир емую до пограничной кри10 i вой жидкости, перед ее поступлением в i детандер 3, The refrigerant (. Helium) is pumped by compressor 1 partly to, expander 2 and partly to expander 3, cooling the expanders, respectively, in the heat exchanger 4 and in the return flow I and 5 exchangers 5 and 6, coming from the cooling chamber 7 and leaving of the expander 2. In the heat exchanger 6, only a part of the flow is cooled, which is expanded to the boundary curved liquid i
