Principle of Constant Humidity and Temperature Machine

The principle of the constant temperature and humidity machine combines a refrigerant circulation system, air circulation system, electrical control system, temperature and humidity sensors, control system, refrigeration system, and humidification system. These systems work together to precisely control the environmental temperature and humidity. Its working process is roughly as follows:
Refrigeration System. This system typically uses compressor refrigeration, where the refrigerant evaporates and absorbs heat in the evaporator, removing heat from the environment to lower the temperature.
Humidification System. This system usually employs ultrasonic humidification or electrode-type humidification, increasing environmental humidity by spraying water mist or steam into the environment.
Dehumidification System. This system achieves dehumidification by lowering the temperature; air passes through the evaporator and is cooled below the dew point temperature, condensing moisture from the air to achieve dehumidification.
Control System. This system is the core, responsible for comprehensively controlling the working states of refrigeration, heating, humidification, and dehumidification to achieve constant temperature and humidity effects.
Air Circulation System. This system generally consists of a centrifugal fan and the motor driving it, providing air circulation within the testing machine. Additionally, the constant temperature and humidity machine also features functions such as purification and ventilation.
