But at present our country market selling refrigerators mostly using the traditional mechanical type temperature control, the control precision, single function, has the advantages of simple control method is difficult to meet the requirements of the development of refrigerator. With the economic development and people39。s living standards further improved, the multifunctional development of increasingly high demand. As the MCU performance is good, strong control function, reliable work, low cost and other advantages, is now in the home appliance products has been widely used. Facing the domestic refrigerator development present situation, the technique is pared with other developed countries have a certain gap, we in the original basis of the refrigerator is improved, making it suitable for use in contemporary fashion, energy saving and environmental protection, intelligent, precise temperature control of the development mode, make people experience have never even heard of it personalized feeling, fast and the original is no longer a dream. A new generation of products in control also increased in artificial intelligence, is home appliance of superior performance, the use of more convenient and reliable. Refrigerator temperature control system is the use of temperature sensor acquisition of refrigerator and freezer room temperature and evaporation the use of MCU in digital signal processing, so as to achieve the purpose of intelligent system may realize the electric refrigerator refrigerator and freezer room temperature setting, refrigerator automatic defrosting, the door alarm function. The design of the second chapter discusses the hardware design third chapter discusses the system software design. Based on the direct cooling type refrigerator cooling system improvement and using fuzzy control technology to realize the refrigerator, double temperature double control, make refrigerator according to use conditions change rapidly and reasonably adjusting cooling capacity, and the energy saving effect is good.
