Summary
Design optimization of a round-tube-plate-fin type CO2 gas cooler is presented in this paper for commercial refrigeration applications. Based on the total heat rejection requirement for a 98 kW cooling capacity system at a design point, a gas cooler with certain heat transfer surface area can be determined for a chosen approach temperature. Coil pressure drop is an outcome of a design and varies with the circuiting arrangement. A parametric study was conducted to study the impact of the coil structural change on system energy efficiency using coil circuiting, i.e. coil pressure drop as a design parameter. The study showed that there was an optimal pressure drop for gas cooler designs that provided maximum system efficiency while meeting the required performance.
