Claim 6:
7. The method for calculating the heat exchange amount according to claim 1, wherein when the multi-connection air-conditioning system is in a heating operating condition, and the obtaining of the total heat exchange amount of the multi-connection air-conditioning system comprises:
obtaining a flow rate of a compressor of the multi-connection air conditioning system;
obtaining a specific enthalpy of a heat exchange medium at a discharge port of the compressor of the multi-connection air conditioning system and a specific enthalpy of a heat exchange medium at an inlet of an electronic expansion valve of the multi-connection air conditioning system; and
calculating the total heat exchange amount of the multi-connection air conditioning system according to the flow rate of the compressor of the multi-connection air conditioning system, the specific enthalpy of the heat exchange medium at the discharge port of the compressor of the multi-connection air conditioning system and the specific enthalpy of the heat exchange medium at the inlet of the electronic expansion valve of the multi-connection air conditioning system.
