FIELD: refrigerating compression plants working at supercritical high pressure.
SUBSTANCE: proposed compression plant includes compressor (1), heat-liberating heat exchanger (2), expansion unit (3) and heat-absorbing heat exchanger (4) connected in closed circulating loop which may work at supercritical high pressure. Cooling agent charge and structural members of plant are rated at pressure inside plant during idle time below 1.26 of critical pressure of cooling agent when temperature of entire plant is set at level of 60°C. Carbon dioxide or mixture of agents containing carbon dioxide is used as cooling agent for plant.
EFFECT: simplified construction and enhanced efficiency.
