However, the GWP value of R410A is larger than that of R22. The "Kyoto Protocol" has listed R410A as a greenhouse gas for controlled emissions. All R410A is by no means a long-term alternative.

Abstract

The invention discloses a compressor and an air conditioning system with the same. The compressor comprises a shell, an air cylinder assembly and a motor assembly; the shell is provided with an exhaust outlet; the air cylinder assembly is arranged in the shell and provided with a compression chamber; the motor assembly is arranged in the shell, a first fluid channel communicating the compression chamber with the exhaust outlet is arranged in the motor assembly, a second fluid channel is limited between the motor assembly and the shell, and refrigerant adopts difluoromethane; the smallest cross section area of the first fluid channel and the smallest cross section area of the second fluid channel in the flowing direction of the refrigerant are denoted as G1 and G2 respectively, the exhaust volume of the compressor is denoted as D, and G1, G2 and D meet the relation: f=D*Rhod / G1, h= D*Rhod / G2, wherein 0.2g / cm<2><=f<=3.8g / cm<2>, 0.12g / cm<2><=h<=1.3g / cm<2>, and Rhod=0.079 g / cm<3>. According to the embodiment of the compressor, air exhausting and oil returning are more smooth, the power dissipation is low, and the operating efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, and more specifically, relates to a compressor and an air conditioning system having the same. Background technique [0002] R22 refrigerant has been listed as a phase-out refrigerant by the "Montreal Protocol". Europe and Japan have already begun to switch to R410A refrigerant replacement, and the United States has also begun to ban the use of R22 in new refrigeration products. China has also accelerated the pace of R22 phase-out, and in 2015 it will meet the requirement of reducing the baseline level by 10%. And some major domestic brands have also begun to launch environmentally friendly air conditioners with R410A as the refrigerant. However, the GWP value of R410A is larger than that of R22. The "Kyoto Protocol" has listed R410A as a greenhouse gas for controlled emissions. All R410A is by no means a long-term alternative. [0003] As one of the alternative refrigerants, ...
