LIQUID SYSTEM FOR COMBINED NATURAL COOLING AND MECHANICAL COOLING Russian patent published in 2019 - IPC F25B25/00 F25B41/04 

FIELD: cooling or freezing equipment.

SUBSTANCE: refrigerating system containing refrigerating circuit and natural cooling system. Natural cooling system includes a fluid cooling circuit and a natural cooling circuit. Fluid cooling circuit is thermally and hydraulically connected to the refrigerating circuit so that the cooling fluid medium of the cooling circuit of the fluid medium is configured to transfer heat to the coolant. Natural cooling circuit is thermally and hydraulically connected to the refrigeration circuit so that the natural cooling fluid of the natural cooling circuit is configured to absorb heat from the coolant. Natural cooling circuit and the fluid medium cooling circuit are thermally and hydraulically connected through a natural-cooling heat exchanger. At least one valve is configured to control flow in the natural cooling circuit. Each of the loops is a closed loop. Refrigerating system is made with possibility of operation in mode of natural cooling, mode of mechanical cooling and combined mode of natural and mechanical cooling.

EFFECT: technical result is higher efficiency of operation, simplified design, which leads to reduced occupied area.
