Air conditioning system and control method thereof

Abstract

The invention relates to the technical field of air conditioners, particularly provides an air conditioning system and a control method thereof, and aims to solve the problem that an existing air conditioning system cannot realize constant-temperature dehumidification. To this end, the air conditioning system according to the present invention comprises: a plurality of outdoor heat exchangers capable of switching between series connection and parallel connection; the indoor heat exchangers can be switched between series connection and parallel connection; the control method comprises the steps that according to the working mode of the air conditioning system, the connecting modes and the participation number of the outdoor heat exchangers and the indoor heat exchangers are determined; in the dehumidification mode, air is cooled and dehumidified through the downstream indoor heat exchanger, and then is heated through the upstream indoor heat exchanger; the constant-temperature dehumidification and the heating dehumidification can be realized, the constant-temperature dehumidification and the heating dehumidification can be realized not only under the heating and refrigerating modes, but also, the application range is relatively wide, and the constant-temperature dehumidification and the heating dehumidification can be suitable for various weathers.
