1. A method for calculating a heat exchange amount of a multi-connection air conditioning system, the multi-connection air conditioning system comprising a plurality of indoor units, and the method for calculating the heat exchange amount comprises:
obtaining a total heat exchange amount of the multi-connection air conditioning system;
obtaining an inlet air temperature of each indoor unit;
obtaining a two-phase saturation temperature of each indoor unit;
obtaining an air supply volume of each indoor unit;
obtaining a heat exchange area of each indoor unit; and
calculating a heat exchange amount of each indoor unit according to the total heat exchange amount of the multi-connection air conditioning system, 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; and
controlling an operating status of the multi-connection air conditioning system by controlling the operation of at least one element via a controller communicatively coupled to at least one sensor.
