A scroll compression has become the prevalent technology used air-conditioning and refrigeration systems. The compression chamber consists of two spiral shaped vanes that form pairs of chambers. A crankshaft imposes an orbital translation on one of the vanes, which reduces the volume of the chambers, thereby compressing the gas trapped within the chamber. A hole is placed at the center of the fixed spiral. The moving spiral will uncover the hole, which serves as an exhaust port. This project studies the exhaust flow area as a function of crank angle. Additionally, the project assesses the sensitivity of the exhaust flow area to the defining spiral parameters, along with the size and placement of the port.
