Embodiment 1

[0057] The debugging method of embodiment 1 is: when Figure 5 For the users in the high area corresponding to the first-stage cold water pipeline, because the actual occupancy rate is lower than the design value, the actual heating demand of the users in the high area decreases, which is lower than the design heat supply, while the middle area and the low area (corresponding to the system The actual heating demand of the second stage and the third stage) is equal to the design heat supply. At this time, by adjusting the opening of the total flow regulating valve 16 of the primary network, the total flow of the primary network is reduced, and the total valve is adjusted so that the flow of the primary network is about 90% of the design flow; at the same time, the control bypass in the first stage cold water pipeline of the system is adjusted The opening of the first-stage secondary network inlet and outlet bypass valve 1701 reduces the flow of the secondary network water in th...

Abstract

The invention discloses an absorption heat exchanger and a debugging method that can realize multi-region independent heat supply and belongs to the field of energy saving; wherein the secondary water enters the absorption heat exchanger from the cold water pipeline inlet of each level and is fed by each level The outlet of the cold water pipeline is discharged, and the inlet of the hot water pipeline for primary water is connected to the hot water pipeline of the generator in the absorption heat exchanger through the valve of the main pipe of the hot water pipeline; It is divided into two roads, the control bypass and the heat exchange main road, and then the control bypass and the heat exchange main road merge to the outlets of the partitioned cold water pipelines at all levels. The invention divides the cold water pipeline into two branches through the multi-stage independent absorption heat exchange process and the multi-stage independent cold water pipeline, and realizes the purpose of heating multiple independent secondary waterways, so that the system has flexible adjustment capabilities , when the above-mentioned different situations occur, the normal district heating can be completed, and at the same time, the ability of the absorption heat exchanger to reduce the return water temperature of the primary network can be realized.

Description

technical field [0001] The invention belongs to the technical field of energy saving, and specifically relates to an absorption heat exchanger capable of realizing multi-region independent heat supply and flexible adjustment and a debugging method. Background technique [0002] With the development of cities in our country, more and more high-rise buildings have appeared. When heating such buildings, due to the number of floors and high heat demand, problems such as overpressure and vertical hydraulic imbalance will occur when using a single conventional heating system. At present, the solution to the heating problem of this type of building is to use a heating system with secondary network partitions in the heating station. Usually, the secondary network needs to be divided into high, medium and low zones according to the water pressure, and also be divided according to the building function to meet the different heating needs brought about by the difference of different h...
