What is the effect of humidity on a walk-in high and low temperature test system

The operating environment of the laboratory test system is more important, different humidity for the laboratory test system are a certain impact, resulting in the failure of the laboratory test system, so what is the impact of humidity on the laboratory test system? The humidity is high, which reduces the insulation strength of the electrical equipment of the laboratory test system, and the moisture in the air adheres to the surface of the insulation material, forming condensation, reducing the insulation resistance of the electrical equipment, greatly increasing the leakage current of the equipment, causing insulation breakdown, and the leakage inside the switchgear causes creepage and accidents, resulting in electrical faults
.

If the air is not flowing, the mold growth will be rapidly accelerated, so in the case of the same humidity and equal temperature, the mold in indoor equipment is much more
serious than outdoor equipment.

The laboratory test system material itself or the surface of the dirt, it provides the necessary nutrients
for the growth of mold.

After the mold is formed, the mold contains a lot of water, and when the hyphae are covered with a mesh on the surface of the insulator, not only the insulation performance of the product is greatly reduced, but also affects the appearance and logo of
the equipment.

In the process of metabolism, mold often secretes acidic substances
.

The conductive metal and the electrical contact material produce an obscure film, resulting in an increase in
contact resistance.

Especially for the printed circuit board of the laboratory test system, if it is in such an environment for a long time, it will corrode the circuit, which will reduce the accuracy of the instrument, or cause equipment failure, or even burn the instrument
.

After the conductive metal and magnetic conductive silicon steel sheet in the electrical equipment are corroded, the performance and service life of the equipment will be seriously reduced, and after the relative humidity reaches a certain value, the corrosion of the metal in the laboratory special test system will suddenly accelerate
.

Corrosion causes the metal to lose its proper properties
.

The electrical cabinet heat exchanger isolates the air inside and outside the control box to ensure that the air in the box is clean, adopts the heat pipe structure design, has a high efficiency heat exchange ability, simple structure, convenient
maintenance.

The laboratory test system is not used for the general temperature control system, and the influence of humidity on its laboratory test system is still relatively large, so we try to avoid the influence of humidity on the laboratory test system and place it in a special environment
