Energy-saving control method and system for air conditioner

Abstract

The invention provides an energy-saving control method and system for an air conditioner. The energy-saving control method for the air conditioner comprises the steps of calculating an enthalpy valuerange and a moisture content range according to a set temperature control range and a humidity control range, and according to the enthalpy value range and the moisture content range obtained throughcalculation on an enthalpy-humidity map and based on the principle that the change amount of an enthalpy value is minimum, dividing the environment state into a plurality of different areas, wherein each area corresponds to at least one control mode; and calculating a real-time enthalpy value and a moisture content according to the temperature and humidity detected by an air inlet of the air conditioner, matching the real-time enthalpy value and the moisture content with the plurality of areas divided on the enthalpy-humidity map in real time, and controlling according to the control mode corresponding to each area. By the adoption of the technical scheme, temperature and humidity control of the air conditioner is converted into range control from point control, the average energy consumption is reduced by about 30%, real-time matching of temperature and humidity control points and environmental energy is truly achieved, intelligent energy-saving control is achieved, and the control method is low in investment, simple in equipment transformation and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of air conditioner control, and in particular relates to an air conditioner energy-saving control method and control system. Background technique [0002] At present, domestic industrial air conditioners for painting are required to meet a certain temperature and humidity. The control mode is basically single-point control, that is, a fixed temperature and humidity are set within a certain period of time, and then the heating, humidification, surface cooling, etc. are controlled by the program to achieve the set temperature. Temperature and humidity to meet the field use. The temperature and humidity of the external environment are different in different time periods, and the corresponding enthalpy values ​​are also different. The temperature and humidity setting of the air conditioner is a fixed value according to the spring, summer, autumn and winter modes. The temperature and humidity are controlled by a ...

AI Technical Summary

Problems solved by technology

The temperature and humidity of the external environment are different in different periods of time, and the corresponding enthalpy values ​​are also different. The temperature and humidity setting of the air conditioner is a fixed value according to the spring, summer, autumn and winter modes. The temperature and humidity are controlled by a single point and cannot be changed according to changes in the external environment. The energy consumption of the whole system is very high, and the energy waste is relatively large
