Definition of constant temperature and humidity storage cabinet
A constant temperature and humidity locker, literally speaking, should have six functions: first, heating; Second, cool down; Third, humidification; Fourth, dehumidification; Fifth, control; Sixth, storage.

This constant temperature and humidity locker is currently a product produced by a company called Huayu in Shenzhen. I also thought of the constant temperature and humidity test box, which is not difficult to distinguish, one is the storage function and the other is the test function. The following is a little written information collected by personal data. Please read it carefully.

The product introduction is:

Constant temperature and humidity cabinet is a multifunctional storage cabinet, the temperature can be controlled at 15-30 degrees Celsius and the humidity can be controlled at 30%-60% RH. Because its storage temperature and humidity are controllable, there is also the saying of constant temperature and humidity storage cabinet.

Realize the principle of constant temperature and humidity, and realize four functions of heating, refrigeration, humidification and dehumidification in a closed box space.

How to realize the function of constant temperature and humidity? Firstly, through the high-precision temperature and humidity sensing probe placed in the cabinet, the actual temperature and humidity parameter values in the cabinet and those set by the control panel are analyzed. For example, when the temperature in the cabinet is 22℃, the control temperature needs to reach 25℃. At this time, the control system gives a signal, and the signal is transmitted to the heating system, and the heating system starts to work. When the temperature rises to 25℃ or higher than the set value, it stops working. Due to the high-speed imported probe, the measurement error is less than 0.65438 0%, so when the measured temperature is greater than or equal to 25.65438 0 degrees Celsius, the heating system stops working. Similarly, the principles of humidification, dehumidification and refrigeration are the same.

Core principles:

The core of this constant temperature and humidity system is dehumidification system, because there are many things that can be done in the market, such as humidification, heating and refrigeration. Those who know a little understand that these principles are relatively simple. But some customers will also say that dehumidification is also very simple. Isn't there a damp-proof cabinet and other equipment? Moreover, it is relatively cheap, but the function of the moisture-proof cabinet is relatively simple, and it can only prevent moisture and dehumidification. In the same way, it can be seen that the moisture-proof cabinet can only store those items that can be stored in an environment with low relative humidity. If items need to be stored in a storage environment with higher humidity, lower room temperature or higher room temperature, it is definitely not possible.

As mentioned above, the principle of constant temperature and humidity system is that it must be in a closed space, otherwise it will be easily affected by the fluctuation of external temperature and humidity, so it is a joke to open the door many times when considering the customer's picking up the goods. There is also the material of the moisture-proof cabinet is sprayed with metal sheet, and the metal sheet has no heat preservation measures, and the outside temperature is the temperature inside the moisture-proof cabinet. Therefore, it is unrealistic and infeasible to store those fine and valuable documents and articles in a moisture-proof cabinet.

Specific uses of constant temperature and humidity lockers:

Through the understanding of the parameter solution of constant temperature and humidity locker, it can be understood that all items whose quality will be affected by external temperature and humidity should be stored in the locker. The industries involved are libraries, museums, precision electronics, precision instruments, aerospace, power generation, electronic devices, medical devices, automobile manufacturing, audio equipment storage, pharmaceutical industry, scientific research sites, polytechnics, test box manufacturers and other places.
