2. avoid the people to be the expense of being equally shared by all.The vacant room that the no one lives also has temperature owing to absorb the heat of adjacent resident family, can draw the expense that it need be paid with the inventive method calculating, has avoided artificial regulation to be equally shared by all the un-reasonable phenomenon of expense;

3. taken into full account the resident family that influenced by adjacent not heating room.Calculate by the inventive method, reduce as this resident family's room temperature, expense also can reduce, if do not reduce because heating load increases (valve opening increasing) temperature, expense can not increase yet, because by computing method of the present invention, this resident family's weighted value is 1, and the heat expense of increase is born by not heating resident family;

4. effectively control the generation of wasting phenomenon.The computing method according to the present invention, the heat radiation if resident family windows, and indoor temperature remains unchanged, and can cause weighted value to increase, the expense of expenditure also will increase, and with this limit waste, encourages energy-conservation;

5. taken into full account the resident family that is positioned at cold mountain, bottom or top layer.Because cold mountain, bottom or top room thermal load are big, their required heats when doing adjustment are also big.Because the present invention has established the not thermal load benchmark of chummery in calibration process, the calculating of weighted value is standard with own thermal load benchmark just, can guarantee the resident family of cold mountain, top layer, bottom like this, weighted value is identical with normal room when doing adjustment or when running into the thermal load disturbance.
