Problems solved by technology
Its disadvantage is that the dilute lithium bromide solution in the solution tank is only heated once by the solution-solution heat exchanger before entering the generator, which has a limited effect on increasing the temperature of the dilute lithium bromide solution, so that the distilled water in the dilute lithium bromide solution cannot be fully heated inside the generator. Vaporization seriously restricts the working efficiency of the whole absorption machine

The invention discloses an absorption heat exchanger. The absorption heat exchanger comprises a generator, a condenser, an evaporator, an absorber, a solution tank and a cooling agent water tank; internal heating coils in the generator and the evaporator are serially connected to connect with a water inlet pipe and a water outlet pipe of heat source circulating water; a condensation coil in the condenser and an internal cooling coil in the absorber are respectively connected with a water inlet pipe and a water outlet pipe of user circulating water; and lithium bromide solution is heated by a solution-solution heat exchanger and a hot water-solution heat exchanger for two times to enter the internal heating coil in the generator for ternary heating. The absorption heat exchanger effectively increases the temperature of the lithium bromide solution to enable the lithium bromide solution to quickly and efficiently generate the working conditions in the generator so as to prominently improve the working efficiency of a whole absorption heat exchanger unit.
Description
technical field [0001] The invention belongs to the technical field of heat exchange, in particular to an absorption heat exchanger. Background technique [0002] Absorption heat exchangers are also called absorption heat pumps. This heat supply technology based on absorption cycles has begun to be applied in urban central heating systems. It has changed the traditional mode of direct circulation of heat source water for urban heating, and changed it to a mode in which heat source circulating water is used to provide heat source, and the circulating water is heated for users through absorption machines. Its advantages include: (1) It can make full use of heat source circulation The heat source provided by water, the return water temperature of the heat source circulating water is greatly reduced, which is conducive to improving the heat exchange efficiency; (2) The water temperature of the heat source circulating water is not high, and low-temperature heat sources such as sm...
