Tiivistelmä
In China, with the rapid development of economiy, the resources are consumed very seriously. Compared with the developed countries, China’s energy consumption for unit GDP production is more than 6 to 10 times and the energy consumption for unit product production is 50% higher than in the developed countries. Therefore, China is increasing emphasis on energy conservation and is also increasing the awareness of energy saving and environmental protection.
In energy saving measures, the one that reduces energy consumption of the central air conditioning is very important. Because in industrial and commercial buildings, central air conditioning system is a very important part of infrastructure and it is widely used. It takes a large proportion in industrial production and the total daily energy consumption of buildings. In industry, central air-conditioning energy consumption accounts for over 40% of the total energy consumption.
In this thesis, the problem and the cause of the problem were found according to the research of the specific practical problem of the traditional energy saving system. Based on the theory of intelligent building management system (IBMS) and energy-saving central air-conditioning inverter, a means of vector control can be adopted to achieve the integrated use of the technology and a solution to improve the Central Air Conditioner equipment and improve HVAC energy saving control system can be found.
In this thesis, it was studied how to reduce the central air-conditioning energy consumption, and also it was a case study about improvement of Nanchang HKLS air conditioning system. This case study shows the practical design and practical improvement of the project can be known and it is also shown the energy saving result by economic analysis is also presented.
