Anticorrosive low-humidity walk-in test chamber

Abstract

The invention relates to an anticorrosive low-humidity walk-in test chamber. The anticorrosive low-humidity walk-in test chamber comprises a chamber body (1), a heating system, a humidification and dehumidifying system, a refrigeration system and an electrical system, wherein the chamber body (1) is provided with an operating room (3); a humiture circulation system and an air exchanging system are arranged in the operating room (3); the air exchanging system comprises an air inlet valve (4), an air sucking valve (5), a filter screen and a drier; the lateral part of the chamber body (1) is provided with an air inlet and an air return opening; the air inlet valve (4) is arranged at the air inlet; the air sucking valve (5) is arranged at the air return opening; the inner side of the air inlet is provided with the filter screen; an air outlet terminal of the filter screen is provided with the drier; an air outlet terminal of the drier is communicated with the interior of the operating room (3); and the heating system, the humidification and dehumidifying system, the refrigeration system, the humiture circulation system and the air exchanging system are connected with the electrical system. The anticorrosive low-humidity walk-in test chamber has a wide humidity scope, can guarantee that ventilation effect can be achieved at any time in the chamber, meets breathing requirements of operators and ensures safety of operating personnel.

Description

[technical field] [0001] The invention relates to the technical field of environmental test equipment, in particular to an anti-corrosion low-humidity walk-in test box. [Background technique] [0002] Many chemical products, due to the particularity of their ingredients, will inevitably have some corrosiveness, but they are an indispensable part of industrial production. In order to ensure the reliability of their products during use, they must be tested In the laboratory, various simulated aging tests are carried out on the samples to test the stability of the product's performance in various environments, as well as the destructiveness to the environment, so that designers can formulate products that are relatively economical, environmentally friendly, and of good quality. At present, the conventional temperature and humidity testing equipment on the market may have the following problems if the tested product is corrosive: [0003] (1) The corrosion resistance of the 304...

AI Technical Summary

Problems solved by technology

[0003] (1) The corrosion resistance of the 304 steel plate in the inner box is not very good. After a few months, the inner box will rust everywhere;

[0004] (2) Under the action of corrosive gas, the evaporator will soon appear corrosion phenomenon, and the place where the tube wall is thin or welded will be corroded and penetrated, and eventually the refrigeration system will leak refrigerant, and the refrigeration system may be damaged at the same time The core component, the compressor;

[0005] (3) Due to the volatile gas produced by the test sample, if there is no fresh air device, the operator will feel dizzy, nauseous, and even prone to personal safety when entering the inner box to work;

[0006] (4) The humidity range of the test chamber is not very wide, especially low humidity, which cannot simulate the low temperature and dry climate in winter
