CASCADE REFRIGERATING PLANT Russian patent published in 1995 - IPC

FIELD: refrigerating engineering. SUBSTANCE: steam superheat at output of evaporator 5 increases at increased thermal loads (when changing high-temperature mode to low-temperature one). Valve of thermal-control rectifier of thermal vessel 8 of heat system opens due thermal action and some part of liquid coolant starts to circulate along communication line 6. Temperature of steam stream which was overheated in evaporator 5 is cooled till achieving which provided reliable operation of compressor. Working matter of heat system corresponds to coolant circulating in the circuit. EFFECT: improved reliability of operation. 1 dwg
