As can be seen from the above, one compressor 100 may correspond to two indoor units, and the rated cooling capacities of the two indoor units may be the same or different, and are determined according to actual situations. The two paths of refrigerants compressed by the compressor 100 are independent from each other, and the discharge capacities of the two compression units are determined according to the rated refrigerating capacities of the indoor units corresponding to the two compression units; the suction and discharge states (pressure and temperature) of each refrigerant path are determined by the respective indoor unit structures and the corresponding ambient temperatures.
The first communication pipeline is provided with a first throttling valve, the flow of the refrigerant passing through the first communication pipeline can be further controlled, so that flexible control can be realized, the second communication pipeline is provided with a second throttling valve, the flow of the refrigerant passing through the second communication pipeline can be further controlled, and flexible control can be realized. A pair of filters are arranged on two sides of the first throttling valve to filter the refrigerant flowing through the first communication pipeline; and a pair of filters are arranged on two sides of the second throttling valve to filter the refrigerant flowing through the second communication pipeline.
In summary, according to the compressor 100 and the air conditioning system provided by the present invention, one outdoor unit may correspond to two indoor units (i.e. a first indoor unit and a second indoor unit), which is equivalent to that the air conditioning system has two sets of subsystems, one outdoor unit is applied to the two sets of subsystems, and only one motor 120 is provided in the outdoor unit, the motor 120 is connected to the first compression unit 150 and the second compression unit 160 which are independent, and the first compression unit 150 and the second compression unit 160 are respectively connected to the first indoor unit and the second indoor unit, so that the usage of one motor 120 is saved, the energy efficiency of the air conditioning system is improved, and the usage of materials is reduced.
The above description is only for the purpose of describing the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and any variations and modifications made by those skilled in the art based on the above disclosure are within the scope of the appended claims.
