abstract With the continuous progress of human civilization and the rapid development of science and technology, people are more and more eager to improve the quality of life. In order to be able to make people live and work in a comfortable and healthy environment, people have invented the air conditioner. However, the huge energy consumption of air conditioning has intensified the contradiction between energy supply and demand. In this paper, a central air conditioning intelligent controller is designed to reduce the energy consumption of the air conditioner by the intelligent control of the controller. In the beginning, central air conditioning and temperature controller, and the control system is introduced, and then puts forward the design of the system overall scheme and control strategy. The system consists of microcontroller, temperature sensor, keyboard circuit, reset circuit, display module, alarm module, communication and other parts, again in the hardware part detailed paintings of the overall circuit diagram and each part of the circuit components, then write the source program based on the design requirements, and draw the flow chart, and the system simulation. The system through the MCU and temperature sensor can achieve the temperature of the acquisition and control, and can be designed by the design of the key circuit to adjust the upper and lower limits of single-chip microcomputer control temperature. By comparing the temperature and the set temperature range, to control the air conditioning work, to achieve the effect of temperature control.
