Design and experimental analysis of a carbon dioxide transcritical chiller for commercial refrigeration

A model and simulations to investigate the effects of compressor and fans speeds on the performance of CO 2 light commercial refrigerators

“…Cecchinato et al [19] developed a finite volume based simulation model for a carbon dioxide trans-critical 146 chiller. In trans-critical mode, the upper pressure is no longer an independent variable and it is expressed as a 147 function of the refrigerant temperature at the gas cooler outlet, as the back-pressure valve control algorithm 148 requires to assure the highest cycle performance.…”

Modeling and calculation of open carbon dioxide refrigeration system

“…The previous studies on the CO 2 refrigeration systems mainly focused on the transcritical cycle [6][7][8][9][10] and cascade refrigeration systems [11][12][13][14], while open refrigeration systems are less reported. Yan developed an open refrigeration system in a refrigeration lorry [3,15] without considering the effect of storage environment of carbon dioxide on the refrigeration performance and the refrigeration capacity loss.…”

Performance evaluation of an ejector subcooled vapor-compression refrigeration cycle

“…Vapor-compression refrigeration cycles are widely used in a variety of refrigerator, air conditioner and heat pump systems [1,2]. They contribute an appreciable part of energy consumption in energy use, and thus improving their energy efficiency is of paramount importance.…”
