The high and low temperature alternating humidity and heat test chamber simulates the principle of natural climate

40 degrees high and low temperature test chamber temperature representation is generally more, do not know that for the experimental equipment, generally all relative temperature of this definition of an ambient humidity belongs, and a definition of ambient humidity generally refers to the gas in the water and gas sub-working pressure, that is, a temperature of the temperature drainage of a saturated state and a percentage of its vapor pressure ratio where the expression of a percentage
.

High and low temperature test chamber is simulated to simulate the temperature of natural climate, such as subtropical long-term temperature of 40 ° C to a higher level, and Antarctica or Ukraine and other countries around the city long-term temperature of -40 degrees so that it will be lower, people to test the high temperature resistance of the goods, for example: mobile phones, to know whether the mobile phone in the Ji gao temperature or extremely low temperature conditions is not a data signal can voice call, It is necessary to set relative temperatures in people's alternating high and low temperature chambers to simulate this kind of climate
.

In this surface the general cabinet is based on a method of external diffusion to add a standard air pressure in a test chamber of an air humidity of a rising effect, in addition to the appearance of an additional heat
generation in the whole process of humidification is not easy to lift the system software.

That is to say, when a temperature of the key point is specified, a dehumidification effect of the self-spray water appliance belongs
.

Then this ambient humidity is a buffer effect of the key power switch for manipulating the water, and the high and low temperature test damp heat test chamber is therefore initially selected for steam humidification and shallow water plate humidification, then its operation of the whole process is relatively long, and it is also a relatively suitable system software to stabilize the small environmental humidity
.

For the saturation pressure characteristics of water vapor can be understood, a saturation pressure of water vapor is generally only a cover of temperature, and it is not known that it is not related to a gas pressure imposed on water vapor, in which it has been calculated by many selected rational formulas, then the expression of the selection effect
.

A whole process of humidification is actually to increase the working pressure of water vapor, the initial humidification method is to spray water on the wall of the test chamber, according to the manipulation temperature of the water surface saturation pressure to obtain manipulation
