A new type of frost-free freezer refrigeration device with solution dehumidification

Abstract

The invention discloses a novel frost-free freezer refrigerating device with a solution dehumidification function. The novel frost-free freezer refrigerating device comprises a freezing cabinet, and the two sides of the freezing cabinet are provided with a left bin chamber and a right bin chamber correspondingly. The novel frost-free freezer refrigerating device is characterized in that a compressor is arranged in the freezing cabinet and connected with an R1 pipeline, a condenser and an R2 pipeline are arranged in the left bin chamber, and a cooler is arranged in the right bin chamber; the R1pipeline and the R2 pipeline are connected; and the condenser, an R3 pipeline, an R4 pipeline, a first capillary throttling pipe, an air cooler, a second capillary throttling pipe, the cooler and thecompressor are sequentially connected to form a refrigeration circulation pipeline. The novel frost-free freezer refrigerating device has the beneficial effects that the condenser is arranged in an inner space of the freezing cabinet, condensing pipes are provided with fins, a circulating fan sucks cold air, moisture in the cold air is firstly removed through the heat exchanging surface on one side, and then the cold air enters the air cooler, so that it is guaranteed that the surface of the air cooler is not frosted. The novel frost-free freezer refrigerating device has the advantages that energy is saved and the air quality of the freezing cabinet space is improved, and is suitable for being used and popularized.

Description

technical field [0001] The invention relates to a novel frost-free freezer refrigeration device with solution dehumidification, belonging to the technical field of refrigeration. Background technique [0002] The temperature in the freezer is low, and most of the water vapor exists in the form of liquid. These liquids are attached to the inner wall of the freezer. When the temperature reaches below zero, ice crystals will form on the inner wall. After a long day, thick hoarfrost will form in the freezer. . Especially when we store aquatic products, the speed of frosting will be accelerated. Many users are very distressed by the phenomenon of frosting in the freezer, but they cannot close the freezer, because the food will deteriorate, so they have to let it thicken and thicken. Failure to recognize the dangers of frosting in the freezer has inadvertently brought great harm to the freezer and our lives. 1. According to the measurement, when the thickness of frost in the fr...

AI Technical Summary

Problems solved by technology

Frost in the freezer will cause the cooling speed to drop, making it difficult to reduce the temperature to zero to minus five degrees within 30 minutes, which will affect the freshness of the food

3. The temperature in the freezer is very low, but it only inhibits the reproduction speed of bacteria, but cannot kill bacteria, and the frost in the freezer will increase the humidity in the freezer, which provides the best conditions for the survival of bacteria

[0005] However, the existing frost-free freezers all use the air-cooled evaporator to send cold air to the freezing space of the freezer. The frosting evaporator tube cannot be seen when the door is opened, but in fact, the surface of the air-cooled evaporator built in the invisible inner layer is still frosted. It’s just that you can’t see it, and it’s just setting the timing electric heating to defrost. The present invention overcomes the shortcomings of the existing technology and proposes a freezer that really does not frost.
