Influence of the valve-seat gap on the dynamics of reed type valvesInfluence de l'espace siège-soupape sur la dynamique des soupapes à lamelles multiples
(2020-10-01)
One of the main parts of refrigeration compressors is the automatic valve system used to control the suction and discharge processes. Experimental studies of these processes in the compressor environment are complex because ...
Evaluation of an Immersed Boundary Method for solving the fluid structure interaction problem in refrigeration compressor valves
(2014-01-01)
In refrigeration compressors, the suction and discharge valves are responsible for the retention of the refrigerant from the suction chamber to the cylinder and passage from the cylinder to the discharge chamber. As the ...

In refrigeration compressors, the suction and discharge valves are responsible for the retention of the refrigerant from the suction chamber to the cylinder and passage from the cylinder to the discharge chamber. As the ...
Numerical simulation of the flow through a compressor-valve model using an immersed-boundary method
(Hong Kong Polytechnic Univ, Dept Civil & Structural Eng, 2016-01-01)
Hermetic reciprocating compressors are widely used in small- and medium-size refrigeration systems based on the vapor-compression cycle. One of the main parts of this type of compressor is the automatic valve system used ...
Effective force area and discharge coefficient for reed type valves: A comprehensive data set from a numerical studySurface de force utile et coefficient de décharge pour les soupapes à lamelles multiples: Un ensemble complet de données tirées d'une étude numérique
(2019-07-01)
Radial diffusers have been used as valve model to determine effective force area and discharge coefficient of the flow. A comprehensive data set of these parameters is lacking in the literature. Here, we present numerical ...
