WITHDRAWAL OF INSTANTLY RELEASING GAS FROM COOLING SYSTEM HEADER Russian patent published in 2009 - IPC F25B1/00 F25B41/04 F25B49/02 

FIELD: instrument making.

SUBSTANCE: invention relates to cooling system. Cooling system, that serves to circulate supercritical coolant in closed-loop circuit in preset direction, comprises, streamwise, heat-removing heat exchanger (4), intermediate expander (6), header (8), evaporator expander (10), evaporator (14), compressor (20) and pipeline (26) withdraw instantly releasing gas. Pipeline (26) communicates header (8) with compressor (20). Aforesaid compressor allows switching over from intermediate pressure level, whereat instantly releasing has is fed, to low pressure level, whereat coolant, coming out from evaporator (14), is fed. Pipeline (26), which off takes instantly releasing gas, communicates, via heat exchange, with pressure pipeline (24). The latter communicates compressor (20, 22) with heat-removing heat exchanger (4) to superheat instantly releasing gas prior to feeding it into compressor (20; 22). Compressor (20) allows adjusting output capacity adjustment. Proposed cooling system comprises regulator (28) to adjust the capacity of compressor (20) depending upon the amount of instantly releasing gas.

EFFECT: reduced power consumed by compressor.
