The invention provides a compressor single-stage and double-stage conversion assembly, a control method thereof, a compressor and an air conditioning system. The single-stage and double-stage conversion assembly of the compressor comprises the compressor, the compressor comprises a shell, a first air cylinder, a middle cavity and a second air cylinder are arranged in the shell, and an air supplementing and enthalpy increasing opening and an exhaust opening are formed in the shell; exhaust gas of the first air cylinder is conveyed to the second air cylinder through the middle cavity, and the middle cavity is further provided with an air outlet with a valve, wherein the air outlet is communicated with the exhaust port. An air supply enthalpy increasing channel communicated with the air supply enthalpy increasing opening and an exhaust channel communicated with the exhaust opening are arranged outside the shell; one end of a communicating pipeline is communicated with the air supplementing and enthalpy increasing channel, and the other end of the communicating pipeline is communicated with the exhaust channel; and a control valve is arranged on the communicating pipeline. The operation mode that the compressor only completes compression of the first air cylinder can be regulated and controlled, so that the exhaust temperature is increased within a short time, refrigerant and refrigerant oil are promoted to be separated as soon as possible, oil-lacking operation of the compressor is prevented, and reliability is guaranteed.
Description
Technical field [0001] The present application belongs to the technical field of air conditioning system, and specific relates to a compressor single-double-stage conversion component and its control method, compressor, and air conditioning system. Background technique [0002] Double-stage lunquat compressors have accumulated an increasingly important position in air conditioning, heat pump water heaters, frozen refrigeration, and other areas due to their low temperature conditions. [0003] When the two-stage junction compressor and its air conditioning system are applied to the cold area, if it is stopped at low temperatures, the refrigerant will migrate into the compressor, causing a large amount of liquid refrigerant in the refrigeration oil in the compressor. After booting, the refrigerant is dramatically volatilized, and the refrigerating oil will be out of the system; at this time, the low exhaust temperature characteristics of the two-stage lunquat have become disadvanta...
