Example Embodiment

[0047]Bonded belowFigure 1 ~ 4The technical solutions provided in the present invention will be described in more detail.

[0048]Seefigure 1 The embodiment of the present invention provides a refrigerator defrost system, including a compressor 1, a condenser 2, a first heat exchanger 3, a second heat exchanger 4, a first auxiliary branch 14, and a second auxiliary branch 15. The compressor 1 is constructed as a compressed refrigerant. The fluid inlet of the condenser 2 communicates with the fluid outlet of the compressor 1. The first heat exchanger 3 is connected in parallel between the fluid inlet and the fluid outlet of the condenser 2, and the first branch 5 does not set the throttle element, the second branch 6 setting. There is a first throttle element 7; the fluid outlet of the first heat exchanger 3 communicates with the fluid inlet of the compressor 1. The fluid inlet and condenser 2 of the second heat exchanger 4 are connected in parallel between the third branch 8 and the fo...

Abstract

The invention discloses a refrigerator defrosting system, a refrigerator and a refrigerator defrosting method, relates to the field of refrigerator defrosting, and aims to improve the defrosting effect of the refrigerator. The refrigerator defrosting system comprises a compressor, a condenser, a first heat exchanger, a second heat exchanger, a first auxiliary branch and a second auxiliary branch. The compressor is configured to compress a refrigerant. A fluid inlet of the condenser communicates with a fluid outlet of the compressor. A first branch and a second branch are arranged between a fluid inlet of the first heat exchanger and a fluid outlet of the condenser in parallel, and a fluid outlet of the first heat exchanger communicates with a fluid inlet of the compressor. A third branch and a fourth branch are arranged between a fluid inlet of the second heat exchanger and a fluid outlet of the condenser in parallel, the first branch and the third branch are not provided with throttling elements, and the second branch and the fourth branch are provided with throttling elements correspondingly. A fluid outlet of the second heat exchanger communicates with the fluid inlet of the compressor. According to the technical scheme, a frost layer is overall peeled off, and the defrosting efficiency is high.

Description

technical field [0001] The invention relates to the field of refrigerator defrosting, in particular to a refrigerator defrosting system, a refrigerator and a refrigerator defrosting method. Background technique [0002] Refrigerators are used to freeze and refrigerate food. In the related art, a refrigerator includes a freezing chamber, a refrigerating chamber and an evaporation chamber. The evaporation chamber is located on the rear side of the refrigerator. The evaporation chamber is used to generate cool air. The evaporating chamber communicates with the freezing chamber and the refrigerating chamber through respective air passages. The evaporator is arranged in the evaporation chamber. In the related art, the defrosting method of the refrigerator is electric heating defrosting, and the electric heating tube is arranged under the evaporator, and the evaporator is defrosted by heating the air to form natural convection and heat radiation of the electric heating tube. ...
