REFRIGERATING PLANT Russian patent published in 2000 - IPC

FIELD: refrigerating engineering. SUBSTANCE: closed circulating loop of refrigerating plant includes compressor, condenser, throttling valve and evaporator, connected with condenser is external cooling medium loop provided with pump and cooling tower. Both loops are provided with temperature and pressure sensors. Reservoir is mounted in external cooling medium loop. Heat exchanger is arranged inside reservoir; it is mounted in cooling agent loop between compressor and linear receiver. Hermetic reservoir is filled with heat accumulating agent at melting point below maximum permissible condensation point of cooling agent. Heat exchanger is arranged inside this reservoir. Multi-way cocks are fitted in cooling agent loop after compressor between condenser and reservoir in front of linear receiver; they are connected via control members to cooling agent pressure sensor fitted on condenser. Multi-way cock is fitted in cooling medium loop after pump before condenser and reservoir; it is connected via control members to temperature sensor fitted before pump. EFFECT: enhanced and economical efficiency of refrigerating plant. 2 dwg
