Ternary-cycle quick-cooling frost-free refrigerator and continuous operation method thereof

Abstract

The invention discloses a ternary-cycle quick-cooling frost-free refrigerator. The refrigerator comprises a box body and a refrigeration system; an exhaust port of a variable-frequency compressor is connected with a first refrigerant pipeline, and a press chamber condenser, a condensation prevention pipe, a left side condenser and a right side condenser are arranged on the first refrigerant pipeline in series connection mode in the flow direction of refrigerant; the refrigeration system comprises a one-inlet-three-outlet electromagnetic valve, a refrigerating refrigeration mechanism, a variable-temperature refrigeration mechanism and a freezing refrigeration mechanism, wherein the one-inlet-three-outlet electromagnetic valve is provided with a branch control first inlet, a branch control second outlet and a branch control third outlet; a refrigerating capillary inlet, a variable-temperature capillary inlet and a freezing capillary inlet are connected with the branch control first outlet, the branch control second outlet and the branch control third outlet respectively; and an outlet of a freezing evaporator is connected with an air suction port of the variable-frequency compressorthrough a second refrigerant pipeline. The invention further discloses a corresponding continuous operation method. According to the refrigerator and the method, the taint of odor between compartmentscan be avoided, opening and stopping control can be independently carried out on any compartment of the refrigerator, the energy waste is avoided, and two different evaporation temperatures are provided for each compartment, so that quick cooling is realized.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a frost-free refrigerator and its continuous operation method. Background technique [0002] With the improvement of people's living standards and the requirements of the market, people have higher and higher requirements on the function and volume of refrigerators, so many air-cooled refrigerators with large volumes, multiple doors, and multiple temperature zones appear in the market. However, the current air-cooled multi-door refrigerators still mainly use a single evaporator for cooling. The cooling of each room is controlled by the damper switch, and the cold air is sent to different rooms to achieve the purpose of cooling. The air duct structure is relatively complicated, and the wind is circulated. It will lead to the smell of food in the refrigerator, cold room and freezer, and also cause the phenomenon of food drying; specifically, every time the circulating air pas...
