AI Technical Summary
Existing air conditioner distributors require mold making, resulting in long production cycles and making it impossible to design larger pipe diameters. Furthermore, traditional brass distributors cannot meet the needs of distributing large flow rates of refrigerant.
The main pipe, distribution pipe and branch pipe are all customizable pipe structures. The refrigerant is evenly distributed through welding or threaded connection, avoiding the need for mold manufacturing. Metal pipe fittings are used to improve production efficiency.
This achieves uniform distribution of refrigerant during the distribution process, improves the heat exchange efficiency of the air conditioning system, shortens the manufacturing cycle, and reduces costs.
