| 摘要 |
The invention relates to a device (1) for heat exchange in a drainage system and a device for heat exchange on a building and construction site. The device comprises a heat exchange element (2) comprising an external pipe device (10) and an internal pipe device (20), where the internal pipe device (20) is provided inside the external pipe device (10). A coupling device (3) provides a fluid-communicating coupling between the heat exchange element (2), a first fluid connector (4) and a second fluid connector (5). The coupling device (3) comprises an external coupling interface (31) for coupling the heat exchange element (2) to the second fluid connector (5) and an internal coupling interface (32) for coupling the heat exchange element (2) to the first fluid connector (4). The external pipe device (10) comprises a first end (10a) connected to the external coupling interface (31) and a second end (10b) which is closed. The internal pipe device (20) comprises a first end (20a) connected to the internal coupling interface (32) and a second end (20b) which is open. The device (1) is configured so that a heat exchange medium can circulate through the first fluid connector (4), the internal pipe device (20), the external pipe device (10) and the second fluid connector (5). |
