Abstract

The invention discloses an energy-saving control system for air conditioners. The energy-saving control system comprises a central control unit, a detection switch arranged on an indoor ventilation window and a temperature sensor arranged indoors; the central control unit is provided with a timer and a first analog-digital converter used for converting analog signals of the temperature sensor into digital signals, and a brightness detection sensor is arranged indoors; the central control unit is further provided with a second analog-digital converter used for converting analog signals of the brightness detection sensor into digital signals; the energy-saving control system further comprises a control cabinet used for controlling the indoor air conditioners to be turned on. According to the energy-saving control system, the timer is arranged for recording the indoor constant temperature time and the ventilating and window-opening time, the unmanned state is assumed when the set time is up, the air conditioners enter the energy-saving state, and therefore the energy waste is avoided; adjustment and the voltage stabilization operation are carried out on power supply of the air conditioners, and therefore the stability of power supply of the air conditioners can be maintained.

Description

technical field [0001] The invention relates to an air conditioner energy-saving control system. Background technique [0002] When there is no one in the room, if you forget to turn off the air conditioner, the air conditioner may be turned on for a long time, which will cause waste of resources. At the same time, the grid power supply is unstable, which will impact the air conditioner and other household appliances and affect the service life of household appliances. Contents of the invention [0003] The purpose of the present invention is to provide an air-conditioning energy-saving control system, which can improve the problems existing in the prior art. By setting a timer, the indoor constant temperature time and the opening time of the ventilation window can be counted, and it can be recognized as unmanned when the set time is reached. State, so that the air conditioner enters an energy-saving state to avoid energy waste. At the same time, the air conditioner power ...
