Refrigerating system and refrigerating device

Abstract

The invention provides a refrigerating system and a refrigerating device. The refrigerating system comprises a compressor, a condensation device, a throttling device and an evaporation device which are sequentially connected in series to form a loop. Specifically, the evaporation device comprises a first evaporation set and a second evaporation set which are sequentially connected between the throttling device and the compressor in series, and the first evaporation set is arranged on the top wall of an inner container of the refrigerating device. According to the refrigerating system, the second evaporation set supplies the cooling capacity to the side of a freezing chamber, the first evaporation set is arranged on the top wall of the inner container to supplement the cooling capacity to the top of the inner container, and therefore the problem that due to cooling capacity sinking, the temperature in the inner container is unevenly distributed is solved. In addition, according to the scheme, refrigerant flowing out of the throttling device sequentially flows through the first evaporation set and the second evaporation set so that it can be ensured that the first evaporation set has enough high heat exchange to be coordinated with the sinking rate of the cooling capacity, and the requirement for supplementing the cooling capacity to the top of the inner container is met along with sinking of the cooling capacity.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigeration system and refrigeration equipment with the refrigeration system. Background technique [0002] At present, most refrigerators in the market use coiled tube evaporators to provide cooling capacity. Specifically, the evaporator tube is wound on the outer wall of the freezer, and the refrigerant in the evaporator tube absorbs the heat on the inner tank to achieve cooling in the freezer. Air cooling, but due to the sinking of the cold air, the temperature of the upper part of the freezer is often higher than the temperature of the lower part of the freezer, resulting in a large temperature difference between the upper and lower parts of the freezer, resulting in the inner wall of the inner tank or the surface of the food in the inner tank. Severe frosting phenomenon requires the user to clean the freezer compartment of the refrigerator frequently, which greatly...
