The constant temperature and humidity test box is used to test and determine the parameters and performance of finished products such as lamps and power supplies after high temperature, low temperature, alternating humidity and heat or constant temperature test. Mainly high temperature and high humidity, low temperature test, temperature cycle test.
Constant temperature and humidity test chamber consists of two parts: temperature regulation (heating, cooling) and humidification. Through the rotary fan installed in the top of the box, the air is discharged into the box to achieve gas circulation, balancing the temperature and humidity inside the box. The data collected by the built-in temperature and humidity sensor of the box is transmitted to the temperature and humidity controller for editing and processing, and the command of temperature and humidity adjustment is issued, which is completed jointly by the air heating unit, condensation tube and the heating and evaporation unit in the water tank.
Constant temperature and humidity box temperature adjustment is through the box built-in temperature sensor, the collection of data, adjusted by the temperature controller, connected to the air heating unit to achieve increased temperature or adjust the refrigeration solenoid valve to reduce the temperature inside the box, in order to achieve the required temperature control. Constant temperature and humidity box humidity adjustment is through the body of the humidity sensor to collect data, adjusted by the humidity controller, connected to the water tank heating element, through the evaporation of water in the tank to achieve increased humidity in the box or adjust the refrigeration solenoid valve to achieve the role of de-humidification, in order to achieve the required humidity control.
The constant temperature and humidity chamber is equipped with multiple protection measures. The temperature system is equipped with an over-temperature protector under the condition that the maximum safe allowable temperature can be set, and the air heating element can be powered off automatically when the rotating fan stops. Humidification system can stop the power supply with the humidification tank water level is reduced. Refrigeration system also stops working with the increase of the box temperature (over 40℃) or humidity.
In ADAYO lighting constant temperature and humidity test experiment, care should be taken to operate in a power supply within the rated voltage range and when the machine is installed and set up to take care not to allow dust, wire, iron filings or other things to enter, otherwise incorrect operation or malfunction will occur. Please try not to open the door of the test chamber during the work of the instrument, if you must open, you need to do a certain amount of protection work. Ventilation holes of the body need to be kept open to avoid malfunction, abnormal action, reduced life and fire.
As a led ceiling downlights manufacturer, ADAYO lighting is committed to becoming the customer's R&D department and manufacturing department, providing customers with high-quality products and services, and creating value for customers. Save costs while ensuring high quality, and achieve mutual benefit and win-win results.
