Problems solved by technology

In the traditional cold storage system, when the storage door is opened, due to the convective heat exchange formed by the temperature difference between the inside and outside of the storage door, it will cause temperature fluctuations in the cold storage, thereby affecting the quality of the goods stored in the cold storage, and at the same time increasing the operating load of the entire cold storage system. In addition, The air outside the cold storage contains a large amount of water vapor, which will follow into the cold storage and condense on the side of the air cooler, causing severe frosting on the air cooler and further reducing the overall operating efficiency of the cold storage system

Embodiment Construction

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] see figure 1 , figure 2 , the present invention provides a cold storage air curtain system capable of forming a positive pressure space, including a hollow cold storage with a cold storage door 15 for entering and exiting goods;

[0033] The inside and outside sides of the top of the cold storage door 15 are respectively provided with a static pressure box 4 outside the warehouse and a static pressure box 3 inside the warehouse;

[0034] The top of the external plenum 4 is connected with a plurality of external fans 2 (not limited to figure 1 The bottom air outlets of the two shown) are connected;

[0035] The top of the static pressure box 3 in the warehouse is connected with a plurality of fans 1 in the warehouse (not limited to...

Abstract

The invention discloses a refrigeration house air curtain system capable of forming a positive pressure space. A refrigeration house door through which goods enter and exit is installed in a refrigeration house; a refrigeration house-out static pressure box and a refrigeration house-in static pressure box are correspondingly arranged on the inner side and the outer side of the top of the refrigeration house door; the top of the refrigeration house-out static pressure box communicates with air outlets in the bottoms of a plurality of refrigeration house-out fans and communicates with air outlets in the bottoms of a plurality of refrigeration house-in fans; a plurality of refrigeration house-out air supply channels with downward openings are formed in an opening in the bottom of the refrigeration house-out static pressure box; a plurality of refrigeration house-in air supply channels with downward openings and a plurality of refrigeration house-in positive pressure air supply outlets areformed in an opening in the bottom of the refrigeration house-in static pressure box; and refrigeration house-in air return channels and refrigeration house-out air return channels which are used forair return are correspondingly formed inside and outside the refrigeration house door for the air return. The refrigeration house air curtain system is good in heat insulation effect, and air curtains can be used for forming the closed positive pressure space inside and outside the refrigeration house, so that air outside the refrigeration house is effectively prevented from being diffused into the refrigeration house, the temperature in the refrigeration house is kept stable, and the quality of the goods stored in the refrigeration house is ensured.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction, in particular to an air curtain system for a cold storage that can form a positive pressure space. Background technique [0002] At present, with the increase of cold chain demand, my country's cold storage reserves continue to increase, and the resulting energy consumption is also increasing year by year. However, due to the uneven management level of cold storage, different companies attach different importance to cold storage energy consumption. , resulting in the relative energy consumption of cold storage in my country is much higher than the advanced level in foreign countries. Therefore, how to reduce the energy consumption of cold storage becomes very important. [0003] For the traditional cold storage system, it uses the cooling fan to exchange heat with the air in the storage, so as to achieve the purpose of producing a low-temperature environment. In the t...
