S3C44BOX control device to achieve energy-saving method of

This article describes the energy-saving approach,which using S3C44BOX microprocessor and its related software,fan and water-pump-driving motor with variable-frequency of temperature difference data.In the central air-conditioning fans,pumps energy-saving control system,we make the central air-conditioning operates on actual loading,provide the refrigerating and heating capacity to terminal to save energy purposefully.Thus,the energy can be saved.
