Claim 2:
3. The method for calculating the heat exchange amount according to claim 2, wherein the calculating of the weight coefficient of each indoor unit according to the inlet air temperature of each indoor unit, the two-phase saturation temperature of each indoor unit, the air supply volume of each indoor unit and the heat exchange area of each indoor unit comprise:
using the following formula to calculate the weight of each indoor unit:

wcal,i=a1Tain+a2Te+a3TainQa+a5ATainQa+a6ATeQa+7A+a8 Te A+a9;

wherein Tain is the inlet air temperature of the indoor unit, Te is the two-phase saturation temperature of the indoor unit, Qa is the air supply volume of the indoor unit, A is the heat exchange area of the indoor unit, a1 is a first correction coefficient, a2 is a second correction coefficient, a3 is a third correction coefficient, a4 is a fourth correction coefficient, as is a fifth correction coefficient, a6 is a sixth correction coefficient, a7 is a seventh correction coefficient, a8 is an eighth correction coefficient, and a9 is a ninth correction coefficient; and
obtaining the weight coefficient of each indoor unit by dividing the weight of each indoor unit by the sum of the weights of all the indoor units.
