Problems solved by technology

[0004] 1. Freon is generally used as a refrigerant, which is harmful to the environment, and the cooling capacity per unit volume of Freon is small, which makes the overall equipment volume of the pre-cooler large;
[0005] 2. The insulation box and the refrigeration unit adopt a split structure. This structure is not easy to move, is not conducive to transportation, and cannot be quickly moved to the fruit and vegetable picking site. It is difficult to meet the needs of fruit and vegetable pre-cooling in the first time. It is also troublesome to assemble, time-consuming and labor-intensive;
[0006] 3. The installation methods of heat exchange components such as evaporators and condensers in refrigeration units are not scientific enough, and there are common problems of large wind resistance, low heat exchange efficiency, and high energy consumption

Embodiment Construction

[0035] like Figure 1-Figure 3 As shown, a movable integrated carbon dioxide pre-cooler according to the present invention includes an insulated box 1 and a compressor 2 arranged in the insulated box 1, an air-cooled condenser 3, and a first liquid accumulator 4. The first heat exchanger 5 , the gas-liquid separator 7 , the second heat exchanger 6 , the second liquid reservoir 8 , the evaporator 9 , the first fan 10 and the conveyor belt 11 .

[0036] Specifically, the insulation box body 1 adopts a container body, so that the pre-cooler can be pulled by a container truck for transportation. The heat preservation box 1 is in the shape of a cuboid cabinet, which is closed as a whole, and a cavity for setting various components is formed inside. The side wall of the insulation box 1 adopts a sandwich structure, with two layers of stainless steel inside and outside, forming a hollow filling cavity between the inner and outer layers, and filling the cavity with heat insulating ma...

Abstract

The invention discloses a movable integrated carbon dioxide precooler, and relates to the technical field of refrigeration equipment. The system comprises a heat preservation box body, and a compressor, an air-cooled condenser, a first liquid storage device, a first heat exchanger, a gas-liquid separator, a second heat exchanger, a second liquid storage device, an evaporator, a first fan and a material conveying belt which are arranged in the heat preservation box body; the material conveying belt extends from the feeding hole to the discharging hole; the compressor, the air-cooled condenser,the first liquid storage device, the first channel, the third channel and the gas-liquid separator are sequentially communicated, and the liquid outlet end of the gas-liquid separator is communicatedwith the liquid inlet end of the compressor to form refrigerant flowing circulation; and the fourth channel is communicated with the second liquid storage device, and the second liquid storage deviceis communicated with the evaporator to form carbon dioxide flow circulation. The integrated design is adopted, the structure is compact, moving and transporting are convenient, the requirement for rapid pre-cooling of fruits and vegetables can be met, a carbon dioxide refrigerant is environmentally friendly, the refrigerating capacity per unit volume is high, the refrigerating efficiency can be improved, energy consumption is reduced, and the equipment size is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a movable integrated carbon dioxide pre-cooler. Background technique [0002] In 2019, the national vegetable planting area is about 313 million mu, the fruit planting area is about 180 million mu, and the annual output of fruit and vegetable is about 1 billion tons. Among them, for perishable fruits and vegetables, if there is no pre-cooling after picking, the spoilage rate in circulation can reach 30%. The annual loss is about 50 million tons, and the corrosion rate can be controlled within 5% after pre-cooling, which can keep its hardness and freshness and other quality indicators to the maximum extent, and prolong the storage period. [0003] At present, pre-cooling machines are mostly used to pre-cool fruits and vegetables. The pre-cooling machines in the prior art have the following defects: [0004] 1. Freon is generally used as a refrigerant, which is har...
