Abstract
A multi-split air-conditioning system, and a method for calculating a heat exchange capacity thereof. The method includes: acquiring a total heat exchange capacity of a multi-split air-conditioning system; acquiring a pressure difference between two pressure measurement points on each air pipe; acquiring the distance between the two pressure measurement points on each air pipe; acquiring the pipe diameter of each air pipe; acquiring the friction factor of each air pipe; acquiring the density of a heat exchange medium in each air pipe; and according to the total heat exchange capacity of the multi-split air-conditioning system, the pressure difference and distance between the two pressure measurement points on each air pipe, the pipe diameter and friction factor of each air pipe, and the density of the heat exchange medium in each air pipe, calculating a heat exchange capacity of each indoor unit.
