how does an environmental chamber work?

The temperature and humidity environmental chamber can simulate a variety of temperature and humidity natural environments, and is suitable for testing electronic devices, household appliances, food, trolleys, vulcanized rubber, plastic rubber, metal materials and other commodities. So how does the temperature and humidity environmental chamber carry out humidification?

The whole process of humidification of the temperature and humidity environmental chamber is to increase the working pressure of water vapor. The more initial way is to spray water on the test box wall to control the saturation pressure of the water surface according to the operating temperature. The water on the surface of the environmental chamber wall produces a large surface. On this surface, add water vapor pressure to the temperature and humidity environmental chamber according to the method of diffusion to increase the air humidity in the test chamber, because the key to the control of the environmental humidity is the mercury electric contact type conductivity meter is used to carry out simple power switch quantity adjustment, and the adaptability to the operation of the large and backward boiling water tank temperature is weak, so the whole process of operation connection is long, and the alternating cold and humidity can not be considered for the humidification quantity. More requirements are stipulated, and more importantly, in the case of self-spraying on the wall of the chamber, it is inevitable that water drops on the sample will cause different levels of environmental pollution to the sample.

In addition, there are also certain regulations for the drainage pipe in the temperature and humidity test chamber. This method was quickly replaced by steam humidification and shallow water zone humidification. Steam humidification is suitable for central air-conditioning facilities and ventilation duct humidification systems, high-precision humidification sites, etc.
