This constant temperature and humidity storage cabinet, currently a company in Shenzhen Ming for Huayu production of a product. This I also associated with constant temperature and humidity test box, it is not difficult to distinguish, one is the role of storage, one is the role of the test. The following personal collection of information written a little text information, the owner, you look carefully.
Product description:
Constant temperature and humidity cabinet for a temperature can be controlled at 15 - 30 degrees Celsius, humidity can be controlled at 30% - 60% RH multi-functional storage cabinets, due to its storage temperature and humidity controlled characteristics. There are also room temperature and humidity storage boxes, storage cabinets.
The principle of constant temperature and humidity realized by a closed box space, to achieve heating, cooling, humidification, dehumidification of the four major functions.
The constant temperature and humidity function is specifically how to achieve, first through the placement of high-precision temperature and humidity sensing probe in the cabinet, the cabinet will be the actual temperature and humidity parameter values and control panel settings of the temperature and humidity parameter values for analysis. As an example, when the cabinet temperature of 22 ℃, the control temperature needs to reach 25 ℃. At this point, the control system that is to give the signal, the signal is transmitted to the heating system, the heating system began to work, when the temperature rise to greater than or equal to the set value of 25 ℃ that is to stop working, as a result of the use of high progress of imported probes, the measurement error value of less than 0.1%, so when the temperature measurement of the temperature value is greater than or equal to 25.1 degrees Celsius, when the heating system to stop working. Similarly humidification, dehumidification, cooling principle is the same.
Core principle:
The core of the constant temperature and humidity system for the dehumidification system, because humidification, heating, cooling can be done on the market a lot, a little bit of know-how, but also understand the principle of these relatively simple. But some customers will also say that dehumidification is also very simple ah, is not a moisture-proof cabinet and other equipment? And also cheaper, but the moisture cabinet function is relatively single, only moisture dehumidification. That same reason can be known, moisture-proof cabinet can only store those items that can be stored in a lower relative humidity environment, if the storage items need to be stored above the ambient humidity, temperature below room temperature or temperature above room temperature storage environment, it is certainly not.
Previously said, the principle of constant temperature and humidity system, the first condition must be in a closed space content, otherwise it is easy to be affected by the fluctuations of temperature and humidity of the outside world, that is in the consideration of the customer access to the items more than a few times to open the door, that constant temperature and humidity is controlled is a joke. There is also a moisture-proof cabinet materials are sheet metal spraying, sheet metal is not any thermal insulation measures, the outside world how much temperature that moisture-proof cabinet cabinet is how much temperature. So use the moisture-proof cabinet to store those fine valuable documents, objects is unrealistic, is not feasible.
Constant temperature and humidity storage cabinet specific use:
Through the understanding of constant temperature and humidity storage cabinet parameter solution, it can be understood that, where items will be affected by the external temperature and humidity and affect the quality of the items, should be placed in the storage cabinet storage preservation. Involved in the industry are libraries, museums, precision electronics, precision instruments, aerospace, power generation, electronic devices, medical equipment, automotive manufacturing, audio equipment storage, pharmaceutical industry, scientific research places, polytechnic institutes, test chamber manufacturers and other places.
