According to the requirements for preserving cultural relics in museum showcases, the constant temperature and humidity machine must meet the following requirements:
It must not come into contact with chemical components that pollute the air. Do not use chemical methods to remove moisture;
The noise of the constant temperature and humidity machine should not exceed the specified decibel. For example, air conditioning, refrigeration, and dehumidifiers cannot be used. Because they are too noisy and prone to gas pollution, they not only fail to protect cultural relics, but also corrode them.
Using semiconductor refrigeration is the best. It does not produce noise or pollution. It is the direction of research at home and abroad. However, it has not been successful yet. This is because the efficiency of semiconductor refrigeration units is low and the power consumption is large. , the heat dissipation problem is also more difficult to solve.
Although museum display cabinets are used to store valuable cultural relics, the state's investment is still relatively low. The price of constant temperature and humidity machines is relatively high, which is unacceptable to users. If this factor is not considered, then the production will be Useless.
The requirements for constant temperature and humidity machines in museum showcases are: the size must be small. If it is too large, it will not be easy to put into the museum showcase.
The above points are the requirements for the design of constant temperature and humidity machines for museum showcases.
