Frequency Control Technology For Central Air Conditioning System, Energy Saving,

In recent year. with the constantly emerging of the high buildings and large mansions in city and the constantly improvement of the people' s living standards. The people to the ask of the surroundings of the work condition and reside become more and more important. cool in summer and warm in winter is the common need of people. The center air-condition system meet the need of the people. But the energy consumption of the center aid-condition system takes 60% in the buildings every year. So the problem of the saving energy before people.In this text. there is a intelligent control project based on the fuzzy PID. On the one hand. to the more export power motor adopt to fuzzy control. The converter will be applied in the central air-conditioning system. the output power of the electrical load with the changes In many extent. saving energy. On the other hand. At the central air-conditioning systems in general have a system devoted to the health of hot water for the host. In summer. Since the central air-conditioning system in the cooling Water generally only 37 centigrade. it' s hard to the direct use. Use of heat pump units and plate heat exchanger will focus on building water supply to the health needs of the heat and central air-conditioning cooling process of cooling water emissions of heat Linkage. there is a value chain about communication with the heat of the two heating. Building a thermal cycle. In Winter. In buildings it can use water to the fire instead of cooling water. Implementation of heat recycling. to reduce emissions. energy conservation purposes.
