Lithium bromide cold / hot water / heat pump unit

摘要

It includes an evaporator, a condenser, an absorber, an additional water heater and a low temperature generator, and each of the devices is provided with a tube plate (2) and a heat exchange tube (1), and the heat exchange tube (1) is a tube sheet ( The heat exchange tube (1) is a titanium heat exchange tube (1) inserted into the hole (21) of 2), and the titanium heat exchange tube (1) is inside the hole (21) of the tube sheet (2). Lithium bromide cold / hot water / heat pump unit with silicone oil (3) applied to the outside of the pipe end. In addition, other lithium bromide cold / hot water / heat pump units and tube expansion methods are provided. The lithium bromide cold / hot water / heat pump unit has excellent corrosion resistance, is lightweight, and saves materials, while the difficulty of low pipe expansion can be greatly reduced and the sealing property is good.
