Problems solved by technology
However, the actual investigation found that installing a large number of balance valves in the water system only considered the restriction on the flow rate, but caused the resistance of the water system to increase, making the water pump run at a high head for a long time

Embodiment Construction
[0043] The present invention is described below based on examples, but the present invention is not limited to these examples.
[0044] figure 1 It is a flow chart of the data processing method of the air-conditioning water system balance scheme of the embodiment of the present invention. Such as figure 1 As shown, the data processing method includes:
[0045] S100. Obtain a first water system balance solution.
[0046] The first water system balance scheme is obtained according to the fixed buildings. In this embodiment, the first water system balance scheme is provided with pipes, water pumps and terminal equipment, and no valves are provided in the pipes. In this embodiment, the terminal equipment is a fan coil unit or an air conditioner. The water pump is arranged at the water inlet of the cooling water pipeline or at the water return of the chilled water, and is used for delivering water to the air-conditioning system of the fixed building. The water separator of th...

The embodiment of the invention discloses a data treatment method and data treatment device of an air conditioner water system balance scheme. By correspondingly calculating the calculating total flowand the calculating total pressure difference of a first water system balance scheme and a plurality of second water system balance schemes acquired by adjusting the first water system balance schemeaccording to different restraint conditions, water pump selection of corresponding water system balance schemes is determined; and then total costs of the different water system balance schemes are calculated respectively and compared to determine a selected water system balance scheme. According to the embodiment of the invention, due to the above method, the water system balance scheme optimalin comprehensive effect of initial investment, a hydraulic balance effect and running energy consumption can be determined, and energy saving is achieved on the premise that hydraulic balance of a water system is guaranteed.
Description
technical field [0001] The invention relates to the field of HVAC technology, in particular to a data processing method and a data processing device for an air-conditioning water system balance scheme. Background technique [0002] In public buildings, the energy consumption of the central air-conditioning system accounts for about 50%-60% of the total energy consumption of the building, while the energy consumption of the cold station accounts for 50%-80% of the energy consumption of the central air-conditioning. Accounting for about 10%-20% of the energy consumption of the cold station, it is an important part of the energy consumption of the central air conditioning system. [0003] The form of the air-conditioning water system is divided into constant flow and variable flow, both of which are designed to carry out hydraulic balance to meet the hydraulic demand of the most unfavorable loop. In some large-scale centralized energy supply stations, combined with operation m...
