Description
Technical field
The present invention relates to a kind of rotary compressor, particularly a kind of oil supply hole structure of rotary compressor eccentric crankshaft.
Background technique
The R22 refrigeration agent is classified as the refrigeration agent that time limit is progressively eliminated by " Montreal is agreed " book.Europe, Japan begin to turn to the R410A refrigeration agent to substitute already, and the U.S. also will forbid that in 2010 R22 uses in new refrigeration product.China has also accelerated the paces that R22 eliminates, and will be frozen in the average level in 2009～2010 years in 2013, will reach 10% the requirement of cutting down baseline values in 2015.And more domestic main brand also begin to release the environment-friendly air conditioner of R410A as refrigeration agent.Yet the GWP value of R410A is also bigger than R22, and " Kyoto Protocol " classified R410A as the greenhouse gases of controlled discharge, and all R410A never are long-range replacement schemes.
As HCFC (like R22), the alternative refrigerant of HFC (like R410A, R407C)), existing carbon-hydrogen refrigerant industry is the most paid close attention to.But carbon-hydrogen refrigerant is used for air-conditioner system, and a very important problem is arranged, and is exactly that it has high combustibility, must limit the refrigeration agent enclosed volume of hydrocarbon air-conditioner system.So be necessary to reduce the amount of refrigerant in the compressor housing significantly, thereby make the refrigeration agent enclosed volume of air conditioner machine system also be able to reduce.Become the structure have than the hyperbaric chamber in the low pressure chamber of large space and less space can reduce the inner amount of refrigerant of compressor preferably the compressor set inside.
Rotary compressor above compressing mechanism is arranged in motor drive mechanism; It is inner that the lubricating oil sump that is used for lubrication and seal is positioned at the lower shell body of compressor, i.e. the below of motor drive mechanism, like this; Because the distance of compressing mechanism and oil sump is bigger, cause the compressor oil-supplying difficulty.
Summary of the invention
