An evaporation and absorption unit
An evaporator for an absorption heat pump or a single coolant cooling process comprises a number of stacked plates (200; 400) provided with a pressed pattern to hold the plates on a distance from one another to form a heat exchanging strip (300; 500; 700; 2002), vapor leading spaces (295; 495; 2001)...

Zusammenfassung: | An evaporator for an absorption heat pump or a single coolant cooling process comprises a number of stacked plates (200; 400) provided with a pressed pattern to hold the plates on a distance from one another to form a heat exchanging strip (300; 500; 700; 2002), vapor leading spaces (295; 495; 2001) and outer walls (210; 410), the heat exchanging strip being designed such that flow channels are formed by internal surfaces of the strip, said flow channels connecting a heat carrier inlet and a heat carrier outlet, wherein a coolant forms a falling film on external surfaces of the heat carrier channels by being provided above the heat carrier channels by a coolant inlet (240; 440), wherein coolant being vaporized from the external surfaces by heat from a heat carrier flowing from the inlet to the outlet rapidly enters the vapor leading spaces (295; 495; 2001). The vapor leading spaces (295; 495; 2001) are provided between the heat exchanging strip (300; 500; 700; 2002) and the outer walls (210; 410).
