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: the present invention relates to method and device that a kind of temperature/humidity verification box shortens hot and humid degree equilibration time, belong to the temperature/humidity verification box technical field.
Background technology: in the technology, temperature/humidity verification box is the calibration equipment that is used for detecting hair thermohygrometer (meter), wet-and-dry bulb thermometer, digital thermohygrometer and other kinds Temperature Humidity Sensor now.The humidity calibrating scope of temperature/humidity verification box is normally at 30～95%RH, and under hot and humid degree situation, like 40～50 ℃ of temperature, humidity 80～95%RH, it is long to increase the required time of humidity again, and very difficult, even can't reach the requirement of high humility.Relative humidity is the dividing potential drop (Pw) and the synthermal number percent of the dividing potential drop (PN) of saturated steam down of actual institute containing water vapor in the expression air, and promptly HT=(Pw/PN) T * 100%RH representes relative humidity with RH% usually.Reach same relative humidity or saturated humidity, the gas that temperature is high more, the steam vapour amount that needs is many more, and existing temperature/humidity verification box generally is to adopt the method that adds gas in the saturated with moisture replacement calibrating case workspace to improve the relative humidity in the workspace.Therefore under the situation of hot and humid degree; Such as 50 ℃ of temperature; 90%RH brings up to 95%RH with relative humidity, consider the operational throughput of the volume and the moisture pipeline of workspace, and the high humiture in workspace is not guaranteed stable situation; The required equilibration time of such substitute mode can be very long, even can't reach higher requirement.Just can't reach the numerical value requirement of 45～50 ℃ of temperature, humidity 90～95%RH like more existing temperature/humidity verification boxs.Therefore existing temperature/humidity verification box in high temperature, to increase the required equilibration time of humidity long, and hot and humid degree state stablizes inadequately, even the requirement of the high humility that can't reach a high temperature, result of use is not ideal enough.
Summary of the invention
The objective of the invention is to: provide a kind of temperature/humidity verification box that enlarges calibrating humidity range, shortening equilibration time, the high humility that can reach a high temperature to shorten the method and the device of hot and humid degree equilibration time, to remedy the deficiency of prior art.
Temperature/humidity verification box of the present invention shortens the method for hot and humid degree equilibration time; On the saturator in temperature/humidity verification box well heater is installed; When humidity will be improved in the workspace of temperature/humidity verification box; Use well heater that saturator is heated separately, strengthen the amount of humidification of saturated with moisture, again saturated with moisture is sent in the workspace.
Above-mentioned temperature/humidity verification box shortens the method for hot and humid degree equilibration time; When humidity will be improved in the workspace of temperature/humidity verification box under the situation of 35～50 ℃ of temperature, humidity 80～95%RH; Use well heater that the saturated with moisture that saturator produces is heated 2～8 ℃ separately; Strengthen the amount of humidification of saturated with moisture, again saturated with moisture is sent in the workspace.
Above-mentioned temperature/humidity verification box shortens the method for hot and humid degree equilibration time; When humidity will be improved in the workspace of temperature/humidity verification box under the situation of 40～50 ℃ of temperature, humidity 80～95%RH; Use well heater that the saturated with moisture that saturator produces is heated 4～6 ℃ separately; Strengthen the amount of humidification of saturated with moisture, again saturated with moisture is sent in the workspace.
Above-mentioned temperature/humidity verification box shortens the method for hot and humid degree equilibration time; Moisture after heating impacts the temperature in the workspace; Constant temperature water tank is installed in temperature/humidity verification box, and the pipeline of conveying dry gas and moisture passes constant temperature water tank to carry out being connected in the workspace after the temperature constant again.
Temperature/humidity verification box of the present invention shortens the device of hot and humid degree equilibration time; It comprises the workspace (1) of temperature/humidity verification box, on the interface (2) of workspace (1), is connected with dry gas pipeline (3) and moisture pipeline (4) respectively, and dry gas pipeline (3) connects exsiccator (5); Exsiccator (5) connects blower fan (9); Moisture pipeline (4) connects saturator (6), and the import of saturator (6) connects blower fan (13), on interface (2), is connected with atmospheric valve (12); Well heater (7) and temperature sensor (8) are installed on saturator (6).
