In the food processing industry, a stable, clean, and precise temperature-controlled environment is a core prerequisite for ensuring product quality and extending shelf life. Addressing the stringent requirements of high cleanliness, corrosion and rust prevention, and constant temperature and humidity in food workshops, we tailored a 1500㎡ dedicated air conditioning project for this food workshop. With meticulous design considerations, reliable equipment configuration, and an intelligent operating system, it perfectly achieves 8℃ precise temperature control, building a solid temperature control defense line for food production.
