SHELL-AND-PLATE HEAT EXCHANGER AND USE OF A SHELL-AND-PLATE HEAT EXCHANGER

摘要

Disclosed is a shell-and-plate heat exchanger (1) for cooling and condensing a circulating refrigerant. The heat exchanger (1) comprises a desuperheater (2) for lowering the temperature of the gaseous refrigerant to a temperature above the condensation temperature of the refrigerant, wherein the desuperheater (2) is formed by a stack of corrugated desuperheater heat transfer plates (3). The desuperheater (2) is connected to a condenser (4) for condensing a main part of the refrigerant, wherein the condenser (4) is formed by a stack of corrugated condenser heat transfer plates (5). The condenser (4) is connected to a subcooler (6) for further lowering the temperature of the condensed refrigerant, wherein the subcooler (6) is formed by a stack of corrugated subcooler heat transfer plates (7), and wherein the stack of corrugated desuperheater heat transfer plates (3), the stack of corrugated condenser heat transfer plates (5) and the stack of corrugated subcooler heat transfer plates (7) are arranged inside the same common continuous shell (8). The condenser (4) and the subcooler (6) are connected through a liquid refrigerant container (9) arranged bellow the stack of condenser heat transfer plates (5) and/or the stack of subcooler heat transfer plates (7), in that the condensed refrigerant is collected in the liquid refrigerant container (9) from which the liquid refrigerant continues into the subcooler (6) through a subcooler inlet conduit (10). Use of a shell-and-plate heat exchanger (1) is also disclosed.
