Enthalpy increasing structure of compressor and scroll compressor

Abstract

The invention provides an enthalpy increasing structure of a compressor. The enthalpy increasing structure of the compressor comprises a fixed scroll disc, an exhaust valve, a pressure valve module, atop cover and an enthalpy increasing pipe, wherein the fixed scroll disc is provided with a valve base mounting hole, and an exhaust hole positioned on one side of the valve base mounting hole; the exhaust valve is arranged on the fixed scroll disc, and is corresponding to the exhaust hole; the pressure valve module is arranged on the valve base mounting hole; the top cover is tightly connected with the fixed scroll disc, and is provided with an exhaust cavity and a pressure cavity; the exhaust cavity is corresponding to the exhaust valve; the pressure cavity is corresponding to the pressurevalve module; and one end of the enthalpy increasing pipe penetrates through the top cover and communicates with the pressure cavity. The invention provides the enthalpy increasing structure of the compressor, and a scroll compressor with the enthalpy increasing structure of the compressor; the heating quantity of the scroll compressor under low-temperature heating condition is improved; meanwhile, the performance of the compressor is improved; the enthalpy increasing structure can effectively reduce the clearance volume influence of the scroll compressor; the capacity efficiency and the performance of the scroll compressor are improved; and a pressure valve module is simple in design, high in reliability and easy to assemble.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an enthalpy increasing structure of a compressor and a scroll compressor. Background technique [0002] At present, the airflow channels of the existing scroll compressors are as follows: figure 1 and figure 2 As shown, the components of the scroll compressor are composed of a movable scroll 21 and a fixed scroll 22. The refrigerant enters the scroll suction chamber 212 from the scroll suction port 211, and the refrigerant is compressed by the compression chamber 222 to the discharge chamber 223, and finally The refrigerant is discharged through the fixed scroll exhaust port 224 . When the existing scroll compressor operates under heating conditions, especially when the outdoor temperature is very low in winter, the heating capacity will be severely attenuated, which will reduce the comfort perceived by the human body Contents of the invention [0003] In order to sol...
