Something with a long time there will be some small problems, after all, in the use of the process is subject to wear and tear, constant temperature and humidity unit after a period of time there will be some small faults, common is the cold storage compressor return port frost, fine frost generally do not have to deal with this is a normal phenomenon, the compressor frost constant temperature and humidity will continue to work, but if it is serious then it's very troublesome, it means that the constant temperature and humidity machine Can not work properly, can not control the temperature and humidity of the room, which will lead to changes in the environment, the equipment inside the room will be affected. The reasons for frost are as follows:

The working environment of the archive constant temperature and humidity machine: the temperature is 18 ℃ ~ 30 ℃, relative humidity is ≤ 90%.

With the continuous development of science and technology, products are more and more sophisticated, performance is more and more outstanding, more and more functions, especially electronic products.

Cabinet-type constant temperature and humidity machine can be realised in high temperature environment with high power equipment, so heat dissipation has a great influence on the stability and service life of the equipment. At present, air cooling and water cooling are the two mainstream choices. Which kind of heat dissipation?

In order to give full play to the performance of constant temperature and humidity machine, do not affect the test effect of constant temperature and humidity machine, easy to box heat dissipation and maintenance, the installation environment of the equipment should meet the following conditions:

In summer, the unit's ability to control humidity is low, so the adjustment of the unit's cooling capacity is usually only two or three steps. Therefore, it is only suitable for air-conditioned rooms with small changes in humidity load.

The operating system of constant temperature and humidity machine adopts touch screen and control module to stop the setting, monitoring and automatic adjustment of menu parameters. Specific methods are as follows: after the air-conditioning system is energised, the touch screen enters the system operation preparation state after self-checking and stops the system parameter setting.

The display cabinet constant temperature and humidity machine has certain requirements for the operating environment. Firstly, the display cabinet constant temperature and humidity machine needs to be placed in a dry and well ventilated place, avoiding direct sunlight and narrow spaces,
