For：Δ W=2.28kWh.
It is varied for air-conditioning kind in the market using the present invention：Gree, beauty, Haier, Hisense etc., they
Remote controler is different, and the instruction encoding of remote control is different, if doing a system just for a kind of air-conditioning, market is too small, if a kind of sky
Tune does a system, then have a too many type again, heavy workload, when installation is inconvenient to find corresponding system again.Therefore we
Devise infrared learning function, instruction code and storage of the system in the air-conditioning that will be arranged in pairs or groups therewith using preceding study, in case of after
Phase uses.The learning functionality that this system has is the infrared remote control code of direct study air-conditioning, is stored in EPROM, even if being
