Leakage characteristics and an updated volumetric efficiency prediction model of rolling piston type rotary compressor for small capacity air-conditioner and heat pump applications

Numerical investigation on the flow resistance characteristics of balance block in the rotary compressor

“…[3,4] In past decades, many scholars would pay more attention to different types of leakage losses in the cylinder to enhance the thermal performance and improve the efficient of rotary compressor system. Cai et al [5,6] and He et al [7] conducted a theoretical method to calculate several kinds of leakage losses in rotary compressor and proposed the experimental investigation to compare the theoretical results with experimental results, which proved the validity of theoretical method. Pan et al [8] presented a method to analyze leakage mass flow rate of six different leakage patterns, furthermore, verified the simulated results by monitoring the errors between the theoretical refrigerant mass flow rate and the experimental refrigerant mass flow rate.…”

A Review on Sliding Vane and Rolling Piston Compressors

“…Comparing both models, Cai et al [114] concluded experimentally that no leakage model can single-handedly model the leakage across the wide range of operating and geometric variations. Subsequently, a semi-empirical two-phase leakage flow model was formulated, providing greater accuracy than theoretical flow models [115].…”

Döngüsel Kompresörlerde Teknolojik Gelişmeler

“…Dünya nüfusunun artışı ve teknolojinin gelişmesi ile birlikte özellikle gelişmekte olan ülkelerde enerjiye duyulan ihtiyaç ve enerji tüketimi her geçen gün dramatik bir şekilde artmaktadır [1][2][3][4]. Birçok endüstriyel tesiste basınçlı hava sistemleri, elektrik enerji tüketiminde 3. sırada yer almaktadır.…”
