Constant temperature and humidity test

Time:2020-12-28 18:06:13 CTR:

The constant temperature and humidity test chamber is composed of two parts: temperature adjustment (heating, cooling) and humidification. Through the rotating fan installed on the top of the box, the air is discharged into the box to realize gas circulation and balance the temperature and humidity in the box. The data collected by the temperature and humidity sensors built in the box are transmitted to the temperature and humidity controller (micro Information processor) for editing, and issuing temperature and humidity adjustment instructions, which are completed by the air heating unit, condenser tube, and heating and evaporation unit in the water tank.
      The temperature adjustment of the constant temperature and humidity box is through the built-in temperature sensor of the box, collecting data, adjusting by the temperature controller (micro information processor), connecting the air heating unit to increase the temperature or adjusting the refrigeration solenoid valve to reduce the temperature in the box. Achieve the temperature required for control. The humidity adjustment of the constant temperature and humidity box is through the built-in humidity sensor, collecting data, adjusting by the humidity controller (micro information processor), connecting the heating element of the water tank, and evaporating the water in the water tank to increase the humidity in the tank or adjust the cooling Solenoid valve to achieve the dehumidification effect, in order to achieve the required humidity control.
       The constant temperature and humidity box is equipped with multiple protection measures; the temperature system is equipped with an over-temperature protector under the condition of setting the maximum safe allowable temperature, and the air heating element can be automatically powered off when the rotating fan stops; the humidification system can follow the water level of the humidification tank The power supply is stopped when the temperature is lowered; the refrigeration system also stops working as the temperature of the cabinet rises (over 40°C) or the humidity increases.
