Abstract

The invention provides a dynamic hydraulic balance adjusting method and device for a central air conditioning system. The method includes the steps that operating data of all fan coils of the central air conditioning system are obtained, indoor environment data of rooms corresponding to the fan coils are obtained, outdoor environment data are obtained, and supplied water temperature data of a central air conditioning main pipe are obtained; the target indoor environment states of the rooms corresponding to the fan coils of the central air conditioning system are set; the control parameter curve of the central air conditioning system is calculated according to the target indoor environment states of the rooms corresponding to the fan coils and the supplied water temperature data of the central air conditioning main pipe; and the central air conditioning system is controlled to operate according to the control parameter curve. By the adoption of the adjusting method, no monitoring equipment is needed, the dynamic hydraulic balance of an air conditioner water system is achieved through dynamic control over electric two-way valves of the fan coils and setting of the wind speeds of the fan coils, the demand for indoor comfort is met, and energy consumption of the air conditioning system is lowered.

Description

technical field [0001] The invention relates to the field of central air-conditioning system control, in particular to a method for adjusting the dynamic hydraulic balance of 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 ...
