Energy-saving control method and system based on target needs

Abstract

The invention discloses an energy-saving control method and system based on target needs. The energy-saving control method comprises the steps that room information in a building is collected, codingand database building are performed on an air conditioner pipe and an air outlet, a wind speed of the refrigerating capacity is determined, and intelligent air conditioning service is performed. The energy-saving control system includes an indoor air data acquisition module, a pipeline data acquisition module, a storage module, a pipeline coding and database building module, a refrigeration data processing module, an intelligent air conditioning service module and a communication module. The energy-saving control method and system realize the maximum energy saving of controlling the indoor temperature within an allowance range, real-time monitoring and management of the refrigeration and air supply state of each room are achieved, dynamic analysis of the operation of a central air conditioner can be performed, a method for quickly checking and locating abnormal conditions is provided, and the energy-saving control system is accurate and efficient and has higher practical value and wideapplication prospects.

Description

technical field [0001] The invention relates to the technical field of energy-saving control, in particular to an energy-saving control method and system based on target requirements. Background technique [0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air-conditioning systems. This system is different from traditional refrigerant-type air-conditioning systems (such as single-body units, VRV) to centrally process air to meet comfort requirements. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the cooling load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the heat load of the indoor environment. The refrigeration system is a crucial part of the central air-conditioning system, and its type, operation mode, and structural form directly affect the economy...

AI Technical Summary

Problems solved by technology

[0003] Existing central air conditioners generally use the method of matching the room with the air conditioner's external unit. When the room is opened, the corresponding external unit is turned on. It is impossible to effectively control the cooling capacity and wind speed of each room, and it is impossible to accurately control the temperature range and change of each room. The speed is high, the user experience is not good, and the total cooling capacity cannot be effectively used. There will be redundant cooling capacity and wind speed, and energy saving and emission reduction cannot be achieved.

[0004] In addition, the existing central air-conditioning pipelines are arranged too much. Once a pipeline is damaged, it is difficult to check and locate accurately.
