“…Experimental evaluations of the two-stage, dual cylinder rolling piston compressor were carried out which showed that it had higher cooling capacity and COP [209]. To improve performance, a novel capacity modulation method to control compressor operation depending on flowrate requirements was proposed [210] and better performance was obtained when compared to other systems [211]. In addition, an inter-stage vapor injection port was implemented into a two-stage, dual cylinder compressor and a 2% improvement in COP [212] was obtained.…”

Rotary compressors have been employed in heating and cooling for more than a century and are ubiquitous in daily life but there has not been any comprehensive record of their development and technological advances. This review paper attempts to provide a comprehensive account of the advances in R&D and design evolution of these rotary compressors since their inception, namely the sliding vane compressor, rolling piston compressor, and their design variants in open literature. This is to showcase the current state-of-the-art for these compressors so that researchers can use it as a basis for future work. Based on authors’ insight, inter-disciplinary research combined with advancements in ‘disruptive’ technology such as artificial intelligence and advancements in additive manufacturing might be a promising research direction to bring about improvements in rotary compressor performance to meet mankind’s growing needs for cooling and heating applications.

“…However, there are also disadvantages such as sealing, leakage, friction and inertia problems deployed and from other algorithms. While some of the literature studies focus on the mechanical friction problem encountered in the vane [13][14][15][16][17][18][19][20] most of them have turned to new designs in order to decrease the pressure loss and increase the compressor efficiency [21][22][23][24][25][26].…”

Rotary compressors have some advantages such as lower noise, vibration, lower cost and few parts. For this reason, it is preferred more than its substitutes such as piston, screw and sliding compressors in cooling and air-conditioning systems. In this study, two different designs, rolling piston and revolving vane, were made to increase the performance of the double-stage, rotary compressor with a volume of 22.6 cc. When the test results are examined, it is seen that the rolling piston compressor consumes 1.3 times less power than the electric motor for 2700 rpm and 3 bar pressure, due to the lower inertia forces compared to the revolving vane compressor.

“…The model was validated with experimental data finding that the root mean square errors for refrigerant mass flow rate, compressor power input and discharge temperature were accurate to within ±3%, ±3% and ±3 K respectively. Lee et al developed (Lee et al, 2015) and validated (Lee et al, 2016) a deterministic model of a two-stage rotary compressor. The validation considered an R410A rolling piston compressor and 16 experimental test conditions.…”
