According to institutional research, the shipment/retail ratio of the leading companies in the air-conditioning industry improved significantly in July. Gree air-conditioning domestic sales revenue/installation card growth rate was nearly 20%, and the US July air-conditioning shipment/installation card increased by about 30%. The second-line faucet also showed significant improvement. Among them, Meiling and Kelon saw significant improvements in air-conditioning shipments in July. Benefiting from the recovery of the air-conditioning industry chain, the core manufacturers of related parts and components are fully produced.

According to industry insiders, the air-conditioning sector has been in the inventory cycle for two years and is currently in the initial stage of recovery. The peak season is coming, and the 20% increase in air-conditioner retail sales in June reflects this trend. The installation card and shipments in July further indicate that the industry trend is improving. Benefiting from the contraction of shipments in the past two years, the full recovery of the entire industry in 2017 is worth looking forward to.
