Description
Technical Field
The invention relates to the field of refrigeration of refrigerators, in particular to an eddy current refrigeration device applied to a refrigerator, the refrigerator and a using method of the eddy current refrigeration device.
Background
A refrigerating system of refrigerator is composed of compressor, condenser, throttle valve and evaporator. The two are sequentially connected by a pipeline to form a closed system, and the refrigerant continuously circulates in the system to change the state and exchange heat with the outside to realize refrigeration.
The liquid refrigerant absorbs the heat of the cooled object in the evaporator, is vaporized into low-temperature low-pressure steam, is sucked by the compressor, is compressed into high-pressure high-temperature steam, is discharged into the condenser, releases heat to a cooling medium (water or air) in the condenser, is condensed into high-pressure liquid, is throttled into low-pressure low-temperature refrigerant by the throttle valve, and is again discharged into the evaporator to absorb heat and vaporize, so that the aim of circulating refrigeration is achieved. Thus, the refrigerant completes one refrigeration cycle through four basic processes of compression, condensation, throttling and evaporation in the system.
The reduction of the evaporation temperature, which leads to the evaporation pressure P, is necessarily required in order to produce lower temperatures in a single-stage compression refrigeration cycle 0 Drop, condensing pressure P k Is determined by the condensing temperature (assuming that the evaporating pressure is P 0 Indicated that the condensing pressure is P k Indicated), the condensing temperature is limited by the temperature of the cooling medium, and the range of variation is limited. Too low an evaporation temperature will lead to a pressure ratio P k /P 0 Too high a pressure ratio increases resulting in a decrease in unit refrigeration capacity.
The refrigerant in the current refrigerating system is directly conveyed into an evaporator pipeline after being throttled and depressurized by a capillary tube, the refrigerant is gasified and absorbed in the evaporator pipeline so as to realize compartment refrigeration, the evaporating temperature is dependent on the size of the return air pressure, namely, the temperature of the evaporator is determined by the performance of a compressor, and when the temperature of the evaporator needs to be further reduced, the refrigerating system can only be realized by replacing a compressor with lower back pressure or adjusting the circulating quantity of the refrigerant.

the refrigerant comes out of the condenser pipeline, passes through the electromagnetic valve, then is throttled and depressurized by the capillary tube to become low-temperature low-pressure liquid, flows into the vortex chamber from the input port of the vortex refrigerating device, accelerates the spiral pipeline which gradually becomes shallow along the pipeline, and is injected into the pipeline of the vortex chamber from the tangential direction through the angular incision to form free vortex, the rotation angular velocity of the free vortex is larger when the rotation angular velocity is closer to the center, friction is generated between layers of annular fluid due to different angular velocities, and the inner-layer refrigerant has lower temperature; the external fluid absorbs energy, the kinetic energy is increased, and part of kinetic energy is changed into heat energy due to friction with the pipe wall, so that the refrigerant has higher temperature; when the outer layer refrigerant is conveyed to the hot end in the vortex chamber, the outer layer refrigerant is directly output from the outer ring of the hot end outlet, enters the compressor through the hot end outlet of the vortex refrigerating device, and returns to the condenser pipeline; the inner layer refrigerant and the outer layer refrigerant are conveyed to the hot end of the vortex chamber together, and after being blocked by the circular wall plate in the middle of the hot end outlet, the inner layer refrigerant starts to be conveyed in the opposite direction and finally is output from the cold end outlet of the vortex chamber, enters the evaporator pipeline through the cold end output port of the vortex refrigerating device, enters the compressor from the other end of the evaporator pipeline after refrigerating is finished, and returns to the condenser pipeline.
8. The method for using a refrigerator according to claim 7, wherein: the temperature of each port is T1 > T0 > T2.
