Abstract: The air-condition intelligence electric-economized device is a new type of energy saving product which is developed for high-energy consumed refrigeration equipments,such as air-conditioner device and icebox,in household. This device saves the energy through optimizing the compressor’s operating curve.Its hardware is made up of 89S52 processor,SC2272-M4 telecontrol decoding chip,switching power and so on,while the software is made up of initialization module,key code collection,key-press processing,parameters preservation,display module,and compressor control module.This device can be set the electricity-economized rate remotely.It can extend the life span of the air-condition by reducing the start-stop times of the compressors,and can effectively reduce the energy consuming of itself by using small and low-energy consumed switching power.Tested by the national household appliances’ quality supervision and inspection center,this device’s electricity-economized rate is 15%-45%,so it has a bright future of market application.
