Problems solved by technology

[0002] Refrigerants such as R22, R410A, etc., due to the increase in specific volume at ultra-low temperatures, the unit suction capacity of the compressor decreases, resulting in a significant drop in the heating capacity of the compressor, and due to the decrease in the suction capacity of the refrigerant, the unit The flow rate is reduced, and the lubrication and cooling effect on the pump body and motor inside the compressor is not good. The limitation of the compressor will cause large leakage and friction loss. The above factors lead to unsatisfactory performance and reliability of the compressor at low temperature.

Abstract

The invention provides a rotary compressor. The rotary compressor comprises a compressor body (10) and an enthalpy increase pipe assembly (20) connected to the compressor body (10). A ratio of a pore cross-section of an input terminal of an enthalpy increase pipe (21) in the enthalpy increase pipe assembly (20) to that of an enthalpy increase pore (16) is 0.7-1.2, and the enthalpy increase pore has a diameter of 0.1-3.0 mm. The rotary compressor of the invention can increase a unit suction intensity of the compressor under ultralow temperature, enhance lubrication and cooling functions of an internal pump body and a motor of the compressor, and improve reliability of the compressor.

Description

technical field [0001] The invention relates to the field of heating and ventilation, in particular to a rotary compressor. Background technique [0002] Refrigerants such as R22, R410A, etc., due to the increase in specific volume at ultra-low temperatures, the unit suction capacity of the compressor decreases, resulting in a significant drop in the heating capacity of the compressor, and due to the decrease in the suction capacity of the refrigerant, the unit The flow rate is reduced, and the lubrication and cooling effect on the pump body and motor inside the compressor is not good. The limitation of the compressor will cause large leakage and friction loss. The above factors lead to unsatisfactory performance and reliability of the compressor at low temperature. Contents of the invention [0003] The present invention aims to provide a rotary compressor, which can increase the unit suction capacity of the compressor at ultra-low temperature, enhance the lubrication an...
