The invention discloses a display and control method for the reconversion of relative humidity, and solves a problem that humidity cannot be displayed accurately when temperature rises in a vicious circle and measured temperature is greater than preset temperature because environmental experiment equipment employs a relative humidity control method and a water vapor partial pressure method. The method comprises the following steps: calculating a water vapor partial pressure value; calculating a reconverted relative humidity value according to a set temperature value and the water vapor partial pressure value; judging a measured temperature value and a set temperature value; enabling a display to display the reconverted relative humidity value when the measured temperature value is not less than the set temperature value; enabling the display to display the measured relative humidity value when the measured temperature value is less than the set temperature value; and finally carrying out the PID calculation of the output quantity of a humidifier.
Description
technical field [0001] The present invention relates to a temperature and humidity control and display method for environmental test equipment, and more specifically to a control and display method for relative humidity re-transformation of environmental test equipment. Background technique [0002] Environmental test equipment is a test equipment used in a specific temperature and humidity environment. Through the control of temperature and humidity, the temperature and humidity conditions of the test environment are kept within the specified deviation range. In order to achieve this technical purpose, the hardware structure adopted by the existing temperature and humidity controlled environmental test equipment includes: a test tank made of heat insulating boards, the test tank is connected to an air-conditioning room, and the air-conditioning room includes a refrigerator for cooling and dehumidification , blower, heater, humidifier, temperature and humidity sensor and tem...
