摘要： A dual-cylinder two-stage variable capacity compressor is provided, including: a first cylinder, having an exhaust port connected to a first exhaust channel: a second cylinder, wherein the second cylinder is provided with a ventilating slider, and the ventilating slider is provided with a first gas transit channel and a second gas transit channel; wherein, when the ventilating slider is at a first connecting position, the first exhaust channel is connected to a suction channel in a second cylinder when the ventilating slider is at a second connecting position, the first exhaust channel is connected to a second exhaust channel. The compressor of the present disclosure can vary its own capacity, that is, the variation of the compressor's capacity can be realized by arranging a ventilating slider, which will meet the requirements of variation loads of the compressor in different seasons.

摘要： A fresh-air air conditioning system comprises: a first electromagnetic valve connected to a first interior heat exchanger, and the first electromagnetic valve is connected via a first accumulator to a compressor and a third electromagnetic valve; the third electromagnetic valve is connected via a second accumulator to the compressor and a second electromagnetic valve; and the second electromagnetic valve is connected to a second interior heat exchanger. When the first interior heat exchanger or the second interior heat exchanger is closed, the third electromagnetic valve opens so that the first accumulator and the second accumulator simultaneously communicate with the open one of the first interior heat exchanger or the second interior heat exchanger, avoiding poor oil return as a result of prolonged single-cylinder operation of the compressor, and ensuring the reliability of the compressor as well as interior comfort.

摘要： A variable capacity compressor is provided, including: two cylinders and a middle plate; at least one flow channel provided in the middle plate, wherein one end of the flow channel is connected to an exhaust chamber of any one of the two cylinders, the other end is connected to a suction chamber of the other one of the two cylinders. In present disclosure, by setting a flow channel in the middle plate of the variable capacity compressor, the exhaust chamber of one cylinder is connected to the suction chamber of the other cylinder. When the flow channel is completely closed, the two cylinders operate independently; when the flow channel is opened, the refrigerant in the exhaust chamber flows into the suction chamber through the flow channel, that is, the upper cylinders and the lower cylinder are connected to each other, which can adjust the capacity of the compressor.
