Common Issues in the Design and Selection of Air Conditioning Units
Currently, the most common forms of energy utilization include screw chillers, centrifugal chillers, VRV systems, lithium bromide absorption chillers, modular air handling units, ice storage systems, tri-generation systems, municipal energy supplies, and heat pumps. However, our primary focus lies on energy conservation and emission reduction, low operating costs, environmental benefits, and the flexibility to adapt operations based on the specific energy source and load requirements.

Structure, Operating Principles, and Performance of Smoke Extraction Fans
In terms of their main body structure, the smoke extraction dampers within smoke extraction fans are fundamentally identical to fire dampers; however, their control boxes differ slightly. Under normal conditions, the smoke extraction damper remains in a "normally closed" state. In the event of a fire, the damper can be activated either manually—by pulling a steel cable—or automatically, via a power signal transmitted from the fire control center. Upon activation, an electromagnet engages, causing its armature hook to disengage; subsequently, driven by the force of an opening spring, the damper rapidly swings open to facilitate smoke extraction.
