Fonctionnement
Internal recirculating airflow: a fan draws chamber air through a duct containing a heater, refrigeration evaporator, and humidifier/dehumidifier; conditioned air is blown back into the chamber from the top, exchanging heat with the test specimen, then drawn back into the duct for repeated cycling. PID control via Samwon TEMI880 touchscreen controller modulates heating, refrigeration (Tecumseh compressor, servo refrigerant flow for >30% energy saving), and humidification simultaneously to achieve the set temperature and humidity.
