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 pipelines, water pumps and terminal equipment, and no valves are provided in the pipelines. 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 separat...

Abstract

The embodiment of the present invention discloses a data processing method and a data processing device for an air-conditioning water system balance scheme. A plurality of first water system balance schemes obtained by separately calculating the first water system balance scheme and adjusting the first water system balance scheme according to different constraints The calculated total flow and calculated total pressure difference of the two water system balance schemes determine the pump type selection of the corresponding water system balance scheme, and then calculate and compare the total costs of different water system balance schemes to determine the selected water system balance scheme. In the embodiment of the present invention, the water system balance scheme with the best comprehensive effect of initial investment, hydraulic balance effect, and operation energy consumption can be determined through the above method, and energy saving can be realized on the premise of ensuring the hydraulic balance of the water system.

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...
