Technical Analysis of Clean Air Conditioning Control System

The clean air conditioning control system is specifically applied to clean air conditioning systems in industries such as clean rooms, microelectronics factories, semiconductor factories, GMP, biopharmaceutical companies, and chemical clean rooms. It can achieve automatic adjustment of system temperature and humidity, pressure difference, dew point, air volume, and wind speed, as well as various safety protection, interlocking, energy-saving operation and other control functions. It maximizes the control and accuracy requirements of temperature and humidity, pressure difference in clean rooms, and provides a high cleanliness and low-energy consumption indoor environment for enterprise production processes.

Product technical features: The lower the air leakage rate of the air handling unit used in clean engineering, the more energy is saved for customers and the lower the operating costs. The precision of temperature and humidity control in cleanrooms is to meet process requirements, such as in the manufacturing of certain electronic products where strict temperature and humidity control is required. In order to achieve constant temperature and humidity, it is required that clean engineering air handling units have at least cooling, heating, humidification, dehumidification and other functional sections, and require precise control methods;
