The laboratory is a relatively confined space, but the inflow of fresh air is still required to ensure the normal breathing of indoor personnel and ensure that the indoor air pressure is positive.
How does the Humidity Chamber remain stable? Let's take a look at the editor of Huanyi.
1. There will be operators in the laboratory to supervise the temperature and humidity of the indoor constant temperature and humidity box, inquire about experimental policies, and control the testing process. These workers need fresh air for normal breathing, and the survival of microorganisms and bacteria used in experiments also depends on air. (So it is important to maintain air circulation in the laboratory)
2. Frequently inject fresh air into the room without affecting the indoor temperature and humidity. The outside air will bring in some other microorganisms, bacteria, etc. to affect the experimental policy, so there must be a special ventilation system, and the indoor air pressure is positive to prevent this phenomenon from happening. This will ensure the accuracy of the Humidity Chamber when doing experiments.
3, the laboratory planning needs to consider the requirements for housing construction, the height of the building should be above 2.8m (referring to the clearance height under the chess beam). The surrounding of the building is free of vibration, strong magnetic field, heat source, peculiar smell, pollution, etc. Meet the basic requirements of laboratory application: the air supply adopts the orifice type, with the upper air supply and the lower return air. (So the equipment site environment will also affect the accuracy and service life of the test).
