This paper is concerned with rolling piston type rotary compressor for alr conditioner. rotating · motion of the rolling piston is theoretically analysed using mathematical model which consists of dynamic equation of rolling piston, equation of force equilibrium and equation of bearing characteristic. Also the motion in operating compressor is measured by(More)
Atmospheric methane (CH4) increased from ∼900 ppb (parts per billion, or nanomoles per mole of dry air) in 1900 to ∼1800 ppb in 2010 at a rate unprecedented in any observational records. However, the contributions of the various methane sources and sinks to the CH4 increase are poorly understood. Here we use initial emissions from bottom-up inventories for(More)
We have being tried to evaluate exactly performance of hermetic rolling-piston type rotary compressor using for domestic room air conditioner. The performance is evaluated concerning with volumetric efficiency and consumption power. Our evaluating approach was founded expelimental measurement and logical calculation. The volumetric efficiency in this naper(More)
