“…From equation (1) and using the method illustrated by Song et al, 37 the motion characteristics of the vane in the harmonic profile cylinder is presented in Figure 8(a). And according to equations (3), (11), and (13) to (15), the motion of the vane in the RVC with the new combined profile cylinder is depicted in Figure 8(b). Comparing Figure 8(a) with (b), the following conclusions are arrived at: (i) The fullness of the vane displacement in the combined profile cylinder is larger than the vane in the harmonic profile cylinder, and this makes the suction volume of the compressor with combined profile cylinder larger than the compressor with harmonic profile cylinder; (ii) the velocity of the vane located in the combined profile cylinder is larger than the vane located in the compressor with harmonic profile cylinder nearby 30 and 135 .…”

“…Valenti et al 10 found the evidence that spraying the lube oil in compressor is one way to increase the efficiency of compressor through experiments. Fukuta et al 11 established vane side force model with considering hydrodynamic lubrication, which can be used to simulate the influence of viscosity of lubricating oil and magnitude of clearance at the vane side on the lubricating characteristics, analyze the vane behavior and improve performance and reliability of the compressors. Platts 12 established the hydrodynamic model of sliding vanes in sliding vane air compressors and 1 analyzed its characteristics.…”

Inner wall profile of the cylinder in a rotary vane compressor (RVC), which influences the motion characteristics of vanes, suction volume, friction characteristic, etc., plays an important role in the performance of the compressor. This work mainly aims at the profile design of a new cylinder for a double-acting RVC with harmonic profile cylinder on the basis of not changing integrate size. According to the relation between cylinder profile and vane motion characteristics, a method for the cylinder profile design is proposed in this paper. With an assumed vane motion, equations of the cylinder profile, cell volume of the compressor as well as pressure angles between vanes and cylinder inner wall are constructed preliminarily. And then through adjusting parameters and optimization with an independently developed procedure, a new cylinder with the so-called combined profile is obtained. Theoretical analysis of the cell volume variations and the pressure angles between vanes and cylinder are conducted. The results show that there is neither rigid impulse nor soft impulse between vanes and cylinder due to the vane continuous motion including displacement, velocity and acceleration. And the pressure angles between vane and cylinder and working volume of the compressor with the new profile cylinder are superior to harmonic profile cylinder, which is useful for the reduction of friction power in the operation of compressor. Experiments show that the cooling capacity and COP of the test refrigeration cycle with the proposed combined profile cylinder is higher than the compressor with harmonic profile cylinder. And the volumetric efficiency and isentropic efficiency of the compressor with combined profile cylinder have better performance. This method can be applied to the design of the cylinder for multiple-acting rotary vane compressors, rotary vane expanders and vane pumps.

“…Early designs used non-metallic vanes, such as polyimide vanes which assumed Coulomb type friction with a friction coefficient of 0.11 at the vane tip [9]. As operating pressures and speeds increased, metallic vanes were introduced, and with the presence of the lubricating oil, hydrodynamic lubrication models were developed to study the oil film thickness and friction at the vane tips [17] and sides [40]. Under such conditions, the friction coefficient was measured to be 0.055 by Cipollone et al [27] and an empirical value of 0.065 was obtained by Bianchi and Cipollone [20] in another study.…”

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.
