Abstract

The invention provides a dynamic hydraulic balance adjustment device for a central air conditioning system. The device includes: an acquisition unit for acquiring operation data of each fan coil of the central air conditioning system, indoor environment data of rooms corresponding to the fan coils, outdoor environment data and water supply temperature data of a central air conditioning main pipe;a setting unit for setting target indoor environment states of the rooms corresponding to the fan coils of the central air conditioning system; a first calculating unit for calculating a control parameter curve of the central air conditioning system according to the target indoor environment states of the rooms corresponding to the fan coils and the water supply temperature data of the central airconditioning main pipe; and a control unit for controlling the central air conditioning system to operate according to the control parameter curve. The device achieves dynamic hydraulic balance through dynamic control over fan coil electric two-way valves and fan coil air speed setting, the requirement of indoor comfort is met, while the energy consumption of the air conditioning system is reduced, and the installation cost is low.

Description

technical field [0001] The invention relates to the field of central air-conditioning system control, in particular to a dynamic hydraulic balance adjustment device for the central air-conditioning system. Background technique [0002] With the development of economy, more and more buildings adopt central air-conditioning system. According to the available statistics, the energy consumption of the central air-conditioning system accounts for more than 40% of the total energy consumption of the building. As energy and the environment become an issue of increasing concern, more and more attention has been paid to the energy saving of the central air-conditioning system. [0003] During the operation of the central air-conditioning system, hydraulic imbalance is one of the main causes of energy waste. Due to the hydraulic imbalance of the central air-conditioning system, the flow of various pipelines and equipment in the system is unreasonably distributed, and the flow flowin...
