Multi-connection air conditioning system and method for calculating heat exchange amount thereof

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.
