Therefore, they are simply referred to as central ducted air conditioners here. Cumulative shipments from January to June 2021, announced by AHRI on August 13, 2021, increased by 19.1% compared with the same period last year. In particular, the shipment increases in April and May were remarkable, with year-on-year increases of 55.2% in April and 31.5% in May.
