REFRIGERATING UNIT Russian patent published in 2014 - IPC F25B5/00 F25B39/02 F25D11/02 

FIELD: heating.

SUBSTANCE: invention refers to refrigerating unit (1) that includes external housing (2), at least one refrigerating compartment (3) for storage of cooled products (5) and refrigerating circuit (6) with evaporator (4) for cooling of refrigerating compartment (3). Evaporator (4) includes the first element (7) of evaporator and the second element (8) of evaporator; besides, the first element (7) of evaporator is located outside refrigerating compartment (3), and the second element (8) of evaporator is located inside refrigerating compartment (3). The first element (7) of evaporator is made in the form of a helix evaporator, envelops refrigerating compartment (3) and includes the pipelines carrying cooling agent, which are wound around the refrigerating compartment and are in heat-carrying contact with it. The first element (7) of evaporator and the second element (8) of evaporator are connected in series; besides, the cooling agent circulating in refrigerating circuit (6) of the refrigerating unit first flows through one evaporator element, and then through the other evaporator element, or they are parallel connected.

EFFECT: increasing efficiency, and cooling or freezing capacity.
