Abstract

The invention provides a compressor and an air conditioning system. The compressor comprises a motor component, a pump body component, a liquid distribution device component, a refrigerant pipe and acontrol valve; the pump body component comprises a crankshaft, an upper flange, a lower flange, a lower cover plate and a cylinder component; one side, away from the cylinder component, of the lower flange is provided with a cavity; the side wall of the lower flange is provided with a first air suction hole and a second air suction hole which communicate with the cavity; the liquid distribution device component is arranged at the external of a shell component; an outlet pipeline of the liquid distribution device component is connected with the first air suction hole; the first end of the refrigerant pipe is connected with an inlet pipeline or an outlet pipeline of the liquid distribution device component; the second end of the refrigerant pipe extends downward from an upper direction of the motor component and is connected with the second air suction hole; and the control valve is arranged on the refrigerant pipe to control the opening degree of the refrigerant pipe according to the degree of superheat of exhausted air of the compressor. By adopting the compressor provided by the invention, the risk of liquid hammer of the compressor can be lowered, so that separation of a slidingsheet of the compressor from a roller is prevented, vibration noise of the compressor is lowered, and the performance and the reliability of the compressor are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a compressor and an air conditioning system. Background technique [0002] When the rotary compressor operates at light load and low frequency, due to the small cooling / heating load, it is easy to cause incomplete evaporation of the evaporator. The refrigerant coming out of the evaporator is a gas-liquid two-phase state. When the gas-liquid mixed refrigerant enters the compression It is easy to cause liquid shock in the cylinder of the compressor, which is very harmful to the compressor: first, it will increase the power of the compressor, which is easy to cause wear and tear, which is very unfavorable to the reliability of the compressor; second, it may cause the rollers to separate from the slides, The impact between the sliding vane and the roller will cause abnormal noise and affect the reliability. At the same time, the separation of the roller and the sliding vane ...
