A transcritical vapour compression refrigeration apparatus including: a compressor, a gas cooler, an economiser, an evaporator and a refrigerant; the refrigerant being compressed in the compressor, heat being rejected from the compressed refrigerant at supercritical pressure in the gas cooler, the cooled compressed refrigerant being then expanded in a first stage to first temperature and pressure conditions in the economiser and then expanded in a second stage to second temperature and pressure conditions; a stream of refrigerant from the economiser at s...
The invention claimed is: 1. A transcritical vapour compression refrigeration apparatus which comprises: a reciprocating refrigerant compressor, a gas cooler, an economiser, an evaporator and carbon dioxide (R-744); said compressor being operative to compress to supercritical pressure the carbon dioxide in two separate streams, said gas cooler being operative to reject heat from the compressed carbon dioxide at supercritical pressure in the gas cooler, said evaporator being operative to expand the cooled compressed carbon dioxide in a first stage to fir...
