In order to deeply understand the internal thermodynamic process of a variable speed rotary compressor with large displacement, the P-V diagram was measured as an important way to analyze efficiencies of the compressor. A testing compressor was modified for measurement of the internal dynamic pressure...
Theoretical and Experimental Study on Rotary Compressor with Double Vapor Injection and Its System This paper takes three kinds of double vapor injection compression cycle as the research object, that is, the two-stage compression cycle with double vapor injection on low-pressure cylinder and intermedi...
Hence, if the cooling potential of today’s compressor and evaporator coils aren’t compromised, the compressor run time would be reduced considerably without affecting cooling effectiveness. In both the cases the total energy consumed will be the same just like the difference between 110v and 220v...

9.11) and the other is because of the operating characteristics of the compressor (see Figs. 6.3 and 6.5Fig. 6.3Fig. 6.5). An additional problem with dense phase conveying, in sliding bed flow for powdered materials, is that the minimum value of conveying air velocity is dependent on the ...

The pressure detection unit is used for detecting the internal pressure in a compressor air cylinder; the rotary encoder is arranged on a compressor crankshaft and can coaxially rotate with the compressor crankshaft; the control unit transmits the pressure signal sampled by the pressure detection ...
The rotary encoder is used for monitoring transient pressure variation of suction and discharge valve port and internal cylinder during compressor running. And it can measure precisely the ...
