Energy-saving method and system for central air conditioner

Abstract

The invention relates to the intelligent control technology, in particular to an energy-saving method and system for a central air conditioner. The energy-saving method includes main steps that: working parameters of the air conditioner are collected through a data collection module, simultaneously human body information and environment information are collected through a sensor device, the collected information is transmitted to a cloud platform to be analyzed, whether the current operation parameters of the air conditioner are reasonable is judged, and if the current operation parameters are reasonable, the operation parameters of the central air conditioner are set according to the human body information and the environment information, and control signals are transmitted to the central air conditioner; the central air conditioner adjusts the working mode according to the control signals; and the result is fed back to a user through a display terminal. The energy-saving method and system for the central air conditioner have the advantages of achieving energy saving, simultaneously being capable of performing real-time monitoring, accordingly timely giving scale cleaning prompts, achieving further energy saving and being capable of being integrated with other systems conveniently and capable of being used by users conveniently, and furthermore is especially applicable to the central air conditioner.

Description

technical field [0001] The invention relates to intelligent control technology, in particular to an energy-saving monitoring method and system for central air-conditioning. Background technique [0002] The design of the central air-conditioning system usually calculates its maximum load according to the extreme climate conditions where the building is located, and thus determines the installed capacity of the air-conditioning host and the water supply flow of the air-conditioning water system. However, in fact, the maximum cooling load (or maximum heating load) occurs only for a very short time each year. Most of the central air-conditioning systems operate under partial (low) load most of the time, and the actual air-conditioning load averages only Therefore, the phenomenon of "big horses and small carts" appears, which not only wastes a lot of energy, but also brings a series of problems such as equipment wear and tear, and shortened life span. For a long time, when the ...
