    • A counter-current heat exchanger (1) for use in transferring heat from a hot water output to a cold water input in a plumbing system. The heat exchanger (1) has upper (2) and lower (3) plates with a heat exchange layer (4) therebetween. The heat exchange layer (4) has upper (4a) and lower (4b) sides. A first conduit (7) for the hot water output is formed between the upper side (4a) of the heat exchange layer 4 and the upper plate (2) and a second conduit (8) for the cold water input is formed between the lower side (4b) of the heat exchange layer and the lower plate (3). The first (7) and second (8) conduits are formed as spirals with the heat exchange layer (4) forming a boundary therebetween with the first conduit (7) positioned above the second conduit (8) and the heat exchange layer connected to the lower plate (3) via a sealed connection.
    • 一种逆流热交换器(1),用于将热量从热水输出传递到管道系统中的冷水输入。 热交换器(1)具有上板(2)和下板(3),板之间具有热交换层(4)。 热交换层(4)具有上侧(4a)和下侧(4b)。 在热交换层4的上侧(4a)和上板(2)之间形成用于热水输出的第一导管(7),并且用于冷水输入的第二导管(8)形成在下部 热交换层和下板(3)的侧面(4b)。 第一(7)和第二(8)导管形成为螺旋状,其中热交换层(4)形成它们之间的边界,其中第一导管(7)位于第二导管(8)上方并且热交换层连接到 下板(3)通过密封连接。

    • The invention relates to a floor drain comprising a drain compartment having a bottom, at least one side and an open upper portion. The bottom and the at least one side together define a space to collect waste water. The bottom comprises an opening for a drain trap. The floor drain further comprises a heat exchanger element, receivable in the space of the drain compartment, for transferring heat present in the waste water to fresh water. The heat exchanger element is provided with a first connection and a second connection. The first connection and the second connection are arranged inside the space of the drain compartment. A first conduit is connected to the first connection and a second conduit is connected to the second connection.
    • 本发明涉及一种地漏(1),其包括具有底部(4),至少一侧(6)和敞开的上部(8)的排水室(2)。 底部(4)和至少一个侧面(6)共同限定了用于收集废水的空间(10)。 底部(4)包括用于排水阱的开口(11)。 地漏(1)还包括可接收在排水室(2)的空间(10)中的用于将存在于废水中的热量转移到淡水中的热交换器元件(14)。 热交换器元件(14)设置有第一连接件(16)和第二连接件(20)。 第一连接件(16)和第二连接件(20)布置在排水室(2)的空间(10)的内部。第一管道(18)连接到第一连接件(16)和第二管道(22) )连接到第二连接(20)。
