A heat exchanger and a heat reclaiming system including such a heat exchanger.

摘要

A heat-reclaiming system includes a heat exchanger (16) providing for heat transfer from warm used laundry water to cold fresh laundry water. The heat exchanger is formed with interior ducts (34) which define a space for the transport through the heat exchanger (16) of the cold water. A shell (44,54) encloses the ducts, and the ducts (34) and shell (44,54) together define a space for the transport through the heat exchanger (16) of the used laundry water. The shell (44,54) is formed in two parts, one part (44) being movable to expose the ducts (34) for cleaning. The heat exchanger (16) is mounted above a pit (36) that stores the used laundry water before it is introduced into the heat exchanger (16). A pit cover plate (70) that normally covers the pit (36) but exposes the pit when the shell (44,54) is removed. This minimises heat loss from the pit during operation.
