Influence of resistance of heat exchangers on air duct system of indoor air conditioners

Establishes a 3D model for the indoor air conditioner composed of the cross flow fan and heat exchanger, and simulates four type models with different resistance coefficient and the same heat exchanger structure and arrangement. Based on the simulation results, analyses the difference of flow field of the air duct system of indoor air conditioner as the resistance of heat exchanger changing, and states the change of the flow rate and the influence of resistance on inlet of cross flow fan.
