Abstract
The application of carbon dioxide as natural refrigerant in commercial refrigeration systems has attracted higher interest in recent years for its promising energy efficiency and ecological sustainability. This paper presented the development of a low side scroll compressor for the bottle cooler application in the trans-critical cycle. Experimental tests were performed in two different temperatures of the outlet refrigerant of the gas cooler with the same operation speed. For comparison of performance of the prototype, a small commercial reciprocating compressor was tested at the same operational conditions. Experimental results show that scroll compressor performed significantly better than the small commercial reciprocating compressor at all setting operational modes.
