Method and apparatus for humiture test box shortening high-temperature high moisture-humidity balancing time

Abstract

The present invention discloses a method and a structure of a temperature and humidity testing chamber for shortening the time of balancing high temperature and high humidity. A heater is fixed on a saturer inside the temperature and humidity testing chamber. When the workaround of the temperature and humidity testing chamber is want of higher humidity, the saturer is solely heated by the heater to increase the quantity of saturated moisture and then the saturated moisture is delivered to the workaround. The present invention resolves the problems that high temperature and high humidity take a long time to be balanced and even high temperature and high humidity can not be carried out. The heater is used to heat solely the saturated moisture that is brought about by the saturer, which can make the temperature and humidity of the workaround be up to the preset numerical value. In comparison with the testing chamber without the heater, the balance time can be shortened by 20-40 percent, and at the same time, the demand of high temperature and high humidity can be easily attained. Thus, the present invention has the advantages of expanding the scope of humidity test; shortening the balance time; and making the temperature and humidity testing chamber meet the demands of high temperature and high humidity.

Description

Technical field: [0001] The invention relates to a method and a device for shortening the high-temperature and high-humidity equilibrium time of a temperature and humidity test box, and belongs to the technical field of temperature and humidity test boxes. Background technique: [0002] In the current technology, the temperature and humidity test box is used to detect hair temperature and humidity meters (meters), dry and wet bulb thermometers, digital temperature and humidity meters and other types of test equipment for temperature and humidity sensors. The humidity test range of the temperature and humidity test box is usually 30-95% RH. In the case of high temperature and high humidity, such as temperature 40-50 ℃, humidity 80-95% RH, it takes a long time to increase the humidity, and it is very Difficult, or even impossible to meet the requirements of high humidity. Relative humidity is the percentage of the partial pressure (Pw) of water vapor actually contained in the...

Problems solved by technology

Therefore, in the case of high temperature and high humidity, such as at a temperature of 50°C, increase the relative humidity from 90% RH to 95% RH, taking into account the volume of the work area and the transportation volume of the moisture pipeline, and the high temperature and humidity in the work area cannot ensure stability In the case of such a replacement, the balance time required for such a replacement method will be very long, and even higher requirements cannot be met.

For example, some existing temperature and humidity test boxes cannot meet the numerical requirements of temperature 45-50°C and humidity 90-95%RH

Therefore, the existing temperature and humidity test box requires a long time to balance the humidity at high temperature, and the state of high temperature and high humidity is not stable enough, and even cannot meet the requirements of high temperature and high humidity, and the use effect is not ideal.
