Dynamic hydraulic balance adjusting device for central air conditioning system

Abstract

The invention provides a dynamic hydraulic balance adjusting device for a central air conditioning system. The device comprises an acquisition unit, a setting unit, a first calculation unit and a control unit, wherein the acquisition unit is used for acquiring operation data of fan coils 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; the setting unit is used for setting target indoor environment states of the rooms corresponding to the fan coils of the central air conditioning system; the first calculation unit is used for calculating a control parameter curve of the central air conditioning system according to the target indoor environment state of the rooms corresponding to the fan coils and the water supply temperature data of the central air conditioning main pipe; and the control unit is used for controlling the operation ofthe central air conditioning system according to the control parameter curve. According to the device, dynamic hydraulic balance is achieved through dynamic control set for electric two-way valves ofthe fan coils and fan coil pipe wind speed, so that indoor comfort requirement is met, 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...
