Of total production, Window-type models take up 10 percent of total output; floor-standing models account for 5 percent; wall-mounting AC for 73 percent, and central air conditioners, 12 percent.
About 55 percent of products use R22, 17 percent use R407C, and 28 percent use R410A. All R22 used are procured locally from a holding company in Taizhou city, while R407C is sourced from Hang Zhou and South Korea. The R410A is imported from Japan and South Korea.
Manufacturing
Jiangsu Chunlan’s R&D team focuses on improving existing housing designs and intends to develop 10 new models a year. The R&D team has 900 members and works in partnership with various academic institutes and international companies.
The R&D process, described as “10, 100 and 1,000”, usually takes 18 months to two years. At stage one; a new design is manufactured on a small-scale production line with an output of 10 units. Tests are carried out on noise level, and cooling and heating capacities using the air enthalpy method. Performance in extreme environments is also tested.
Jiangsu Chunlan has 24 assembly lines, each with five QC points manned by two to three people at each point. Another two to three QC team members patrol each assembly line. The company also checks air conditioner performance via the helium CNC-leak test system, which emits an alarm when there is a leakage. Finished products are tested on the assembly line and are also put through a voltage testing system.
