Embodiment Construction

[0031] The core of the present invention is to provide an absorption heat exchange unit. The primary side pipeline of the heat exchange unit passes through the heat network heater before entering the heat pump unit, which has a better heat supplement function and increases the primary side hot water. The water supply temperature can increase the temperature difference between the primary side hot water supply and return water, and reduce the operating cost of the absorption heat exchange unit.

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Please refer to figure 2 , figure 2 It is a schematic structural diagram of the first embodiment of the absorption heat exchange unit provided by the present invention.

[0034] In a specific embodiment, such as figur...

Abstract

The invention discloses an absorptive heat exchanger unit which comprises a hot water type absorptive heat pump unit, a water-water heat exchanger and a primary side pipeline and a secondary side pipeline. The primary side pipeline sequentially passes a generator of the heat pump unit and the water-water heat exchanger from water supply to water return. The heat exchanger unit further comprises a heat supply network heater, and the primary side pipeline has to pass the heat supply network heater before entering the generator. Compared with the prior art, the absorptive heat exchanger unit has the advantages that the heat supply network heater can heat the primary side pipeline before the primary side pipeline enters the heat exchanger pump unit, heat compensation is realized, water supply temperature of the primary side pipeline can be further increased, temperature difference between supply and return of primary-side hot water is increased, and initial investment and operation cost of the absorptive heat exchanger unit can be reduced.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to an absorption heat exchange unit. Background technique [0002] As the scale of urban central heating increases year by year, the high-temperature hot water generated by centralized heat sources needs to be transported over a long distance to reach the heating area. In the case of the same heat supply, increasing the temperature difference between supply water and return water can Reduce the flow of water supply, thereby reducing the initial investment in pipelines. At the same time, it can also reduce the power consumption of water pumps, so it can reduce heating energy consumption and heating costs. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an absorption heat exchange unit disclosed in patent CN203177524; the following briefly introduces the working principle and technical defects of the heat exchange unit in the meeting. ...
