Preferably, the semiconductor component includes a first electrode 2816, a second electrode 2817, a third electrode 2818, a P-type semiconductor 2814 and an N-type semiconductor 2815; cold junction 2811 is in contact with second electrode 2817, a first region of hot junction 2812 is in contact with first electrode 2816, and a second region of hot junction 2812 is in contact with third electrode 2818; a first terminal of the N-type semiconductor 2815 is connected to the third electrode 2818 and a second terminal of the N-type semiconductor 2817 is connected to the second electrode 2817; a first terminal of the P-type semiconductor 2814 is connected to the first electrode 2816, and a second terminal of the P-type semiconductor 2814 is connected to the second electrode 2817; the first electrode 2816 is connected to a negative power supply, and the third electrode 2818 is connected to a positive power supply.

Referring to fig. 3, when a current flows through a circuit (P-type semiconductor 2814 and N-type semiconductor 2815 in fig. 3) formed by different conductors, heat absorption and heat release occur at the joints of the different conductors according to the current direction, in addition to irreversible joule heat generation.

The work flow of the compression refrigeration apparatus 282 of the present disclosure includes the following three processes:

and (3) a compression process:

the refrigerant is a substance that is easily liquefied at normal temperature. The refrigerant absorbs heat in the evaporator 2825 and evaporates into low-temperature and low-pressure refrigerant vapor, and in order to change the low-temperature and low-pressure refrigerant vapor into high-temperature and high-pressure refrigerant vapor, the refrigerant is liquefied at normal temperature and compressed by the gas compressor 2824, and the compressed high-temperature and high-pressure refrigerant vapor is sent to the condenser 2823 through a pipeline to be liquefied.

And (3) condensation process:

the compressed high-temperature and high-pressure refrigerant vapor is cooled by air (or cooling water) in the condenser 2823 to release heat and is condensed into a refrigerant liquid.

And (3) an expansion process:

after being liquefied, the refrigerant is throttled and expanded to reduce pressure and adjust flow (the flow can be adjusted by a capillary tube of the expander 2821) and then enters the evaporator 2825. The condensed high-pressure refrigerant liquid is suddenly reduced in pressure by the expansion valve of the expander 2821, and the liquid is rapidly expanded, so that the condensed high-pressure refrigerant liquid is converted into low-temperature low-pressure mist refrigerant and enters the evaporator 2825.
