摘要
A refrigeration apparatus for transcritical operation includes a gas cooler, an aftercooler, an evaporator with a low-pressure liquid separator, a compressor, a first controllable throttling device and interconnecting piping between the mentioned components and in addition a second controllable throttling device and an intercooler that comprises two flow paths separated by heat exchanging surfaces. A first flow path inlet of the intercooler is connected to the gas cooler outlet. A first flow path outlet of the intercooler is connected to the aftercooler inlet. A second flow path inlet of the intercooler is connected to the outlet of the second throttling device. A second flow path outlet of the intercooler is connected to the economizer port of the compressor. The second throttling device inlet is connected to the piping either upstream or downstream of the aftercooler. The second throttling device outlet is connected to the second flow path inlet of the intercooler.
