“…Accordingly, it can be deduced that the average values of the forces acting on the upper vane in the DSVC and SVC are approximately the same. The variations in the forces acting on the upper vane in the DSVC are also similar to those in the SVC, as shown in the simulated results in (Hu et al, 2013). However, as shown in Fig.…”

“…To contribute to the development of a lower cost rotary compressor for electric vehicle air conditioning systems, a novel double-swing vane compressor (DSVC) is introduced in this paper. This type of compressor is designed on the basis of the swing vane compressor (SVC) presented by Hu et al (2013), which is structurally simple and easy to manufacture and also has a higher mechanical efficiency. Compared with the SVC, the work 3 / 38 capacity of the DSVC is significantly increased under the same operating conditions and dimensions by adding an additional vane in the mechanism.…”

“…One end of the lower vane is jointed with the rotor while the other end is inserted into the guide way assembled with the cylinder. Unlike the SVC with a single-swing vane (Hu et al, 2013), the crescent chamber trapped within the cylinder and rotor is divided by the two vanes into two work chambers, namely the former work chamber and the latter work chamber. Each work chamber is connected with a suction valve assembly and a discharge valve assembly.…”

This paper presents a novel double-swing vane compressor (DSVC) for use in electric vehicle air conditioning systems. The design and work principle of the DSVC are introduced, and the dynamics and mechanical efficiency of the mechanism are theoretically formulated and analysed. Under the same operating conditions and dimensions, the theoretical volumetric flow rate of the DSVC is about 1.6 times that of the swing vane compressor (SVC) with a single swing vane and the mechanical efficiency of the DSVC is also greater than that of the SVC. The design of the double-swing vanes improves the load fluctuations on the eccentric and shaft bearings and enhances the operating smoothness of the compressor. Overall, the assessment of the structure and dynamics of the DSVC shows that the DSVC has the advantages of high efficiency, light weight and simple component geometries, which make it well suited to the requirements of electric vehicle air conditioning systems.

“…They found for example that the contact force between vanes ant rotor in compression chamber become maximum near the discharge starting. Another research effort is conducted 24 to study a novel rotary compressor named ''swing vane compressor.'' The previous investigation has shown that this type of compressor has a number of characteristics which are better than their corresponding ones in a sliding vane compressor.…”

Vapor-compression systems are still the most widely used type of automotive cooling systems despite their high energy consumption and negative environmental effects. This article gives a review of the carried out developments and the future trends for this type of automotive airconditioning systems which have served vehicle occupants for more than 50 years. After going over a brief historical progression of the system, the circulating refrigerant developments were presented. Only few refrigerants meet the imposed attributes (e.g. zero ozone depletion potential, low global warming potential), and CO 2 as well as R1234yf have a big potential to be the future refrigerants. Then, the developments related to the other major system components were outlined. In this context, the future trends show that the scroll compressor besides the evaporator and the condenser having parallel flow and micro-channels are the most promising for the next generation of (air-conditioning) systems. Concerning the control of the compressor and the expansion device, the advanced electronic control is the most attractive for the future systems. This is due to its provision to better improvement for the airconditioning system performance. The present vapor-compression airconditioning systems still have some weaknesses despite their eminent achieved improvements. Models developed for airconditioning systems still have some shortcomings (e.g. low accuracy). Also, the test procedures for airconditioning extra fuel consumption are still not worldwide in all aspects. Therefore, more efforts should be made to solve these problems.

 Turbo rotary engines  Two stage turbine  Design parameters Unmanned aerial vehicles and hybrid cars, which are currently being studied extensively, require high efficiency and power-to-weight ratio engines. The Pars engine, which is a rotary engine that have the potential to provide these desired characteristics, consisting of compressor, combustion chamber and turbine, is similar to the single vane rotary refrigerant compressors and expanders used in the industry. In this study, a new twostage turbine was designed in place of the Pars turbine, which has a rotary valve system. Expansion ratio, eccentricity ratio, volume ratio, phase difference angles were determined as design parameters and theoretical moment values were obtained. In the theoretical calculations made, a torque increase of 47% was obtained for equal inlet time angels relative to the rotary valve system in the two-stage turbine. Figure A. Structure of the two stage turbine (a) Volumes and angles of two stage turbine (b) Purpose: In this study, two turbines with rotary vane were connected in series to obtain a double chamber turbine. Thus, the rotary valve mechanism requirement of the Pars turbine has been eliminated. In the newly designed turbine, mechanical efficiency is increased by the removal of the power of the valve mechanism. Theory and Methods: In this study, a double stage turbine was analyzed in order to eliminate the need for a rotating valve that controls the air which is required for the Pars turbine. The effect of turbine eccentricity ratio, volume ratio and phase difference angle on the turbine moment, which is determined as design parameter, was investigated and the turbine and double stage turbine were compared. Results: In the theoretical calculations, an increase of 47% was obtained for the equal input time angles of the double stage turbine according to the rotary valve system turbine. Conclusion: As the eccentric ratio increases in turbines, the turbine size decreases and the pallet loads increase. This reduces the turbine moment due to increased friction losses. The eccentric ratio affects the turbine power more than the other parameters. When the eccentric ratio is doubled for equal input and output angles in the double stage turbine, the expansion rate decreases by 3%. It is seen that the pallet loads increased linearly with the eccentric ratio of the turbine.
