Abstract

The invention relates to a display unit comprising at least one compressor, at least one fluid/gas heat exchanger for cooling the compressed gas, at least one evaporator, at least one expansion device and high pressure conduits connecting the afore-mentioned components with each other to form a transcritical refrigeration circuit, especially a carbon dioxide refrigeration circuit. According to the invention at least the compressor (2) and the fluid/gas heat exchanger (3) are arranged within a compartment (1), which is removable from 225 the display unit (C).
