It is specific as follows that the step (21) sets up air-conditioning group's polymerization model, air conditioner load and tradition energy storage device characteristic phase
Seemingly, can be by electric energy so that in building belonging to being stored in the form of heat energy, the higher energy storage capacity of indoor temperature is smaller, and indoor temperature is got over
Low energy storage capacity is bigger.Assuming that the comfort level scope of user is [Tmin,Tmax], indoor temperature is TmaxWhen energy storage capacity be 0, then it is indoor
Temperature is TinWhen energy storage capacity OinFor：
Oin=C (Tmax-Tin)； (5)
