Cold damage prevention refrigeration house

Abstract

The invention discloses a cold damage prevention refrigeration house, aiming to provide a refrigeration house which can reduce the cold damage caused by the greater temperature difference between the air blast temperature and the temperature in the refrigeration house so as to implement flow equalization in the refrigeration house. An air return jacket is formed between a refrigeration house body and an inner baffle plate; the upper end of the inner baffle plate is provided with an air blast plate; the bottom of the inner baffle plate is provided with a plurality of air return openings; a partition plate is arranged between the air blast plate and the top of the refrigeration house body; a mixed region is formed between the partition plate and the top of the refrigeration house body; a static pressure air blast region is formed between the partition plate and the air blast plate; the middle part of the partition plate is provided with an air blast fan; an air cooler is arranged at one side of the mixed region, and the other side of the mixed region is communicated with the air return jacket; the air return opening of the air cooler is communicated with the air return jacket; and the air blast opening of the air cooler is communicated with the mixed region. Part of the air passing through the air return opening passes through the air return opening of the air cooler and enters the air cooler, is discharged out from the air blast opening of the air cooler, and is mixed with the other part of return air which does not pass through the air cooler, and the mixed air is discharged into the refrigeration house through the static pressure air blast region, thus the temperature difference between the air blast temperature and the temperature in the refrigeration house is reduced, and the generation of cold damage is reduced.

Description

technical field [0001] The invention relates to a chilling injury prevention cold storage, more specifically, relates to a chilling injury prevention cold storage adopting primary return air mixed with static pressure air supply. Background technique [0002] In traditional cold storage, the cold air cooled by the cooling fan is usually sent directly to the cold storage through the air outlet of the cooling fan, absorbs the heat load in the cold storage, and returns to the cooling fan for cooling through the air return outlet of the cooling fan. Due to the size limitation of the air supply port of the cooling fan, the main flow area of ​​the air supply will be formed, which makes this cold air supply method have three obvious disadvantages: [0003] 1. The wind speed in the mainstream area of ​​the cold air sent by the air outlet of the air cooler is relatively high, which will cause a large dry consumption of the items stored in the mainstream area; [0004] 2. The tempera...

AI Technical Summary

Problems solved by technology

[0003] 1. The wind speed in the mainstream area of ​​the cold air sent by the air outlet of the air cooler is relatively high, which will cause a large dry consumption of the items stored in the mainstream area;

[0004] 2. The temperature in the mainstream area of ​​the cold air sent by the air outlet of the air cooler is low, which will cause chilling or freezing damage to the items stored in the mainstream area, and damage the quality of the items;

[0005] 3. In the area outside the mainstream area, the air circulation is poor, which will cause the temperature field and velocity field in the warehouse to be uneven

[0006] At present, in the research of cold storage, the main consideration is how to make the temperature field in the storage uniform, without considering the large difference between the air supply temperature of the cooling fan and the internal temperature of the storage, which is likely to cause the formation of chilling damage to the stored items in the storage
