REFRIGERATING AND/OR FREEZING DEVICE Russian patent published in 2013 - IPC F25B21/00 F25D21/04 

FIELD: heating.

SUBSTANCE: refrigerating and/or freezing device includes an electromagnetic cooling device with a pump, a cold heat exchanger, devices for recording of the temperature value of the cold heat exchanger. The above device has a control or an adjustment unit having the possibility of controlling the temperature and/or mass of heat carrier medium supplied to the cold heat exchanger. Temperature of the cold heat exchanger in the cooling mode is not decreased below 0°C. Electromagnetic cooling device and/or a heat carrier medium supply pump have the possibility of their being operated uniformly and constantly without a defrosting cycle of the cold heat exchanger. The above defrosting cycle is performed only when it is required to decrease the temperature of the cold heat exchanger below 0°C.

EFFECT: reduction of consumed energy amount, preventing or reducing to minimum level of temperature vibrations.
