REFRIGERATING DEVICE AND METHOD TO MAINTAIN CONSTANT SPECIFIED TEMPERATURE IN REFRIGERATING CHAMBER OF REFRIGERATING DEVICE Russian patent published in 2012 - IPC F25D11/02 

FIELD: power engineering.

SUBSTANCE: refrigerating device (10) comprises one first refrigerating chamber (22) and one second refrigerating chamber (24), a heat insulation separating wall (26), which separates chambers, a refrigerating plant (34) with a system of heat removal joined with a space that surrounds the refrigerating device (10). The first refrigerating chamber (22) is cooled down to the first temperature (T1) by removal of the first main heat flow (Q_H1) of the first refrigerating chamber (22) into the space that surrounds the refrigerating device (10). The second refrigerating chamber (24) is cooled down to the second temperature (T2) by removal of the second main heat flow (Q_H2). Maintenance of the second temperature (T2) as constant at the specified value (T2_Soll) is realised with a device (36; 40) of heat transfer by controlled transportation of an auxiliary heat flow (Q_AUX) from the second refrigerating chamber (24) into the first refrigerating chamber (22), or in the reverse direction.

EFFECT: method improvement.
