VACUUM ADIABATIC BODY AND REFRIGERATOR Russian patent published in 2022 - IPC F25D23/06 F25D23/00 F25D11/00 

FIELD: refrigeration equipment.

SUBSTANCE: invention relates to refrigeration equipment. The refrigerator contains at least one main body, a door, an engine room having a compressor and a condenser, an expansion device, an evaporator and a heat exchange pipeline having an exhaust pipeline and an inlet pipeline at least partially connected to the exhaust pipeline. The refrigerant flows towards the evaporator through the inlet pipe. The evaporated refrigerant flows through the exhaust pipe. The vacuum adiabatic body includes: a first plate with the possibility of forming at least a wall section for the first space; a second plate with the possibility of forming at least a section of the wall for the second space; a third space between the first and second plates with a temperature between the temperature of the first space and the second space; a support configured to maintain a distance between the first and second plates; a thermal resistance sheet configured to reduce the amount of heat transfer between the first plate and the second plate; and an opening through which a heat exchange conduit passes between the first space and the second space. At least a portion of the heat exchange pipeline is provided in a fourth space filled with adiabatic material. The fourth space has a volume smaller than the volume of the third space. The area in which the inlet pipe and the outlet pipe exchange heat with each other in the fourth space is larger than the region in which the inlet pipe and the outlet pipe exchange heat with each other in the third space.

EFFECT: invention contributes to reduction of refrigerator heat losses.
