Refrigerated display case

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 a bottom, at a back, and at a top, and with a cooling device (5) that has a refrigerant circuit at least including a compressor (51), an evaporator (50), a condenser (52), and a control device (55), characterized in that propane is contained as a refrigerant in the refrigerant circuit, with a filling capacity of between 300 g and 1500 g the refrigerant circuit has a low-pressure region with an operating pressure of between 0.8 and 2.0 bar and a high-pressure region with an operating pressure of between 20 and 30 bar;

• the compressor (51) and the condenser (52) are positioned spaced apart from each other, particularly in different wall groups;
• the evaporator (50) is positioned in the rear wall group (120);
• the compressor (51) is positioned beneath the evaporator (50) in a lower region of the rear wall group (12) and at least one fan (56) for assisting a flow of cooling air is positioned above the evaporator (50) in the rear wall group (12);
• the at least one fan (56, 57) has a motor over temperature protection;
• the cooling device (5) in the refrigerant circuit has a maximum surface temperature of less than 300° C. during operation;
• the compressor (51) is a hermetically sealed, suction-gas-cooled compressor, and the compressor (51) is situated in a lowest region of the refrigerant circuit in terms of geodetic altitude.
