中国 2 1世纪的空调发展将以变频、健康为主流。2 1世纪空调变频技术是重点。目前 ,日本 80 %是变频热能型空调 ,95 %以上是变频分体机 ,这反映了人们对高效节能的需求。中国是一个资源开发比较落后的国家 ,电力问题一直难以解决 ,一些地方电力不足 ,电压不稳 ,变频技术可以有 The development of air conditioning in China in the 21st century will be dominated by frequency conversion and health. 2 1st century air conditioning inverter technology is the focus. At present, Japan accounts for 80% of variable-frequency thermal energy-type air conditioners and 95% of which are frequency-converting splitters, reflecting the demand for energy-efficient energy. China is a relatively backward resource development country. The power problem has been difficult to solve. In some places, electricity is insufficient, and the voltage is unstable. The frequency conversion technology can have
