    Abstract: A coolant pipe (3, 23) extends on the evaporator plate (1) of a roll bond evaporator. Said coolant pipe (3, 23) has a first connection point (2, 19) on an edge of the evaporator plate (1) and a constriction (4) that adjoins the connection point (2, 19). A section of the coolant pipe (3, 23) extending across the constriction (4) is delimited by branches (6, 7, 22, 24) on both sides. The evaporator plate (1) has a second connection point (8, 20) which is separate from the first connection point (2, 19).

    Abstract: A compression machine includes a refrigerant condenser, an expansion device, a refrigerant evaporator, a first compressor and a second compressor. Each compressor is arranged to receive lower pressure refrigerant vapor from the evaporator and to deliver higher pressure vapor to the condenser independently of the other compressor. The first compressor operates when the compression machine is operating in a first duty mode, for example a water-cooling mode. The second compressor operates when the compression machine is operating in a second duty mode, for example one of a water-heating mode or a brine cooling. The first compressor is selected for optimal performance in the first duty only and the second compressor is selected for optimal performance in the second duty mode only.

    Abstract: A hot gas defrost process is disclosed for defrosting an evaporator of a refrigeration system. In an exemplary embodiment, the hot gas defrost process includes the step of flooding at least one evaporator to be defrosted with liquid refrigerant prior to supplying a hot refrigerant vapor to the liquid flooded evaporator. In an exemplary embodiment, the hot gas process includes the step of suctioning down the refrigeration pressure within the evaporator upon termination of the supplying of the hot refrigerant vapor to the evaporator being defrosted.
