Air conditioner outdoor unit and air conditioning system

Abstract

The present utility model discloses an air conditioner outdoor unit and an air conditioning system. The air conditioner outdoor unit includes a compressor, two outdoor heat exchangers, a gas-liquid separator, and a flow path module assembly. An end port of the suction pipe of the gas-liquid separator at an end away from the gas-liquid separator faces upward. The flow path module assembly includes at least two switching valves and a first flow path module. One of the switching valves is in communication with the first outdoor heat exchanger, and another of the switching valves is in communication with the second outdoor heat exchanger. The first flow path module includes a module body and a plurality of connecting pipes. The module body has a module cavity with a cavity wall provided with at least three through holes. The connecting pipes are correspondingly disposed with and connected with the through holes. The connecting pipes include at least two second connecting pipes and one first connecting pipe. The second connecting pipes are correspondingly disposed with and connected with the switching valves. The first connecting pipe of the first flow path module is disposed on an upper side of the module body, and an end port of the first connecting pipe at an end away from the module body faces downward and is connected to the upward-facing end port of the suction pipe.
