Abstract: A refrigerated display case (1) with at least one unit composed of a plurality of wall groups, namely a bottom group (11), a rear wall group (12), and a top group (13), which delimit a refrigerated chamber (4) at the bottom, at the back, and at the top, and with a cooling device (5) that has a refrigerant circuit and whose components at least include a compressor (51), an evaporator (50), a condenser (52), and an electric control unit (55). A refrigerated display case that is climate-friendly, efficient, and simultaneously safe to operate is achieved in that propane is contained as a refrigerant in the refrigerant circuit, with a filling capacity of more than 150 g.

Abstract: A refrigerated display case (20) having at least one unit composed of a plurality of wall assemblies, namely a bottom assembly (22.3), a rear wall assembly, and a top assembly (22.1), which delimit a cooling space at the bottom, the rear, and the top, and having a cooling unit (1) whose components include at least one evaporator (11), one condenser (13, 13′), and one electric control unit (15). An environmentally friendly refrigerated display case (20) is achieved in that the cooling unit (1) includes at least two closed refrigerant circuits (10, 10′), which convey propane as a refrigerant and are each provided with a compressor (12, 12′), and in order to variably control the cooling output, at least one compressor (12, 12′) is embodied with a speed regulation and at least one compressor (12, 12′) is embodied for operation at a constant speed.

Abstract: A cooling unit having, on two sides, supporting C-shaped lateral frames. The lateral frames are formed from frame profiles having a rear-sided vertical profile and a lower and an upper forward-projecting horizontal profile. A rear wall group having a heat-insulating outer covering is mounted on the vertical profiles, a base group is mounted on the lower horizontal profile and an upper group is mounted on the upper horizontal profile, and the groups surround a cooling chamber from behind, below and above. The construction has at least the outer covering of the rear wall group arranged on the inner side, facing the cooling chamber, of the vertical profile.
