Embodiment Construction
[0023] see Figure 4 , the present invention can realize multi-zone heating absorption heat exchange unit and heat supply system, which includes a two-stage absorption heat pump unit 1 and n heat exchangers (n is a natural number), the two-stage absorption heat pump unit 1 It consists of condenser one 2, condenser two 3, absorber one 8, absorber two 9, generator one 4, generator two 5, evaporator one 6 and evaporator two 7, primary water flows through generator one in series 4. After generator 2 5, enter each heat exchanger. Among them, heat exchanger one 10, heat exchanger two 11, and heat exchanger three 12 are connected in parallel for primary water, mixed after heat exchange, and enter evaporator two 7 and evaporator one 6 in series. There are many ways for primary water to enter the heat exchanger four ~ n, series, parallel or mixed series and parallel. The lead-out point for the primary water to enter the heat exchangers 4~n can be before the generator 14, after the ge...

The invention discloses an absorption type heat exchanger unit capable of achieving multi-area heat supply and a heat supply system, and relates to the technical field of absorption type heat exchangers. Primary water flows through the first generator and the second generator in series and then enters the heat exchangers. Primary water among the first heat exchanger, the second heat exchanger and the third heat exchanger is connected in parallel, mixed after heat exchange and connected in series to enter the second evaporator and the first evaporator. The leading-out point of the primary water entering the heat exchanger 4-n can be in front of the generator I, behind the generator I or behind the generator II. Secondary water in the first subarea enters the first condenser and the first heat exchanger in parallel, secondary water in the second subarea enters the first absorber and the second heat exchanger in parallel, secondary water in the third subarea enters the third heat exchanger, the second absorber and the second condenser in parallel, and the secondary water of the second absorber and the secondary water of the second condenser can also be connected in series. And the secondary water in the subareas 4-n respectively enters the heat exchangers 4-n for heat exchange and temperature rise. According to the invention, the heat adjustment among the partitions is realized through one machine with multiple supplies, the mutual influence among the partitions is effectively reduced, and the device has the characteristics of simple structure and flexible and convenient adjustment.
Description
technical field [0001] The invention relates to the technical field of absorption heat exchangers, in particular to an absorption heat exchange unit and a heat supply system capable of realizing multi-zone heat supply. Background technique [0002] With the acceleration of my country's urbanization process, the heating area and the proportion of energy consumption continue to increase. At the same time, more than 50% of my country's industrial energy consumption is transformed into industrial waste heat. The absorption type large temperature difference heat exchange unit is used for heating, which can reduce the return water temperature of the primary network to below the return water temperature of the secondary network, significantly increase the temperature difference between supply and return water, which is beneficial to waste heat recovery, reduces primary energy consumption, and reduces the cost of transmission and distribution pipelines The initial investment can re...
