A, the fire coal condensing-type cogeneration units generated output p that draws gas _CHP(t) and the heat h that exerts oneself _CHP(t) signal, the action of day part in the time will be regulated in the control cogeneration of heat and power in future;

B, the different air-conditioner power consumption constantly of user p _EHP(t is l) with refrigeration work consumption h _EHP(t, l), control user side different distance user uses the air-conditioner refrigerating capacity, and closes the fan coil amount.
