Scroll Compressor Dynamics : 1st Report, The Model for the Fixed Radius Crank

Building Technologies Office 03.02.02.38 Milestone Report—Compressor Technology Development for Refrigerants with <150 Global Warming Potential

“…In 1984, Morishina et al [10] adopted the concept of the involute of a circle in their model. The displacement volume and pressure ration, radial, and tangential forces were calculated in the analytical model.…”

“…Based on Morishina's work [10], Yanagisawa [16] developed a full scroll compressor geometrical model in 1990, which expresses every chamber volume as a function of orbiting angle by a general formula. This improvement makes the development of a thermodynamic model much easier.…”

Design optimization of scroll compressor applied for frictional losses evaluation

“…The details to fundamental formulas adopted in the study, comprised calculation of the suction volume, compression volume of individual chambers during one orbiting cycle and discharge volume, has been derived by Morishita et al (1984), Morishita et al (1986) and Nieter and Gagne (1992).…”

“…where A i represented the chamber area derived by Morishita et al (1986). Moreover, by neglecting the inertial force with constant speed consideration, the centrifugal force of the orbiting scroll is…”

“…Numerous literatures about STC had been published since 1980s. Among those, the mathematical model including geometrical characteristics, kinematics and dynamics has been disclosed (Morishita et al, 1984(Morishita et al, , 1986. The compression and discharge processes, leakage through clearances and superheat of suction pipe in thermodynamics also have been developed by Nieter and Gagne (1992); Schein and Radermacher (2001) and Chen et al (2002).…”
