The Current Situation Of The Energy Consumption And Total Energy-Conserving Methods Of Central Air-Conditioner In Chinese Building

Nowadays, the problem of energy shortage has been becoming one of the most intractable problem throughout the world. With the rapid development of Chinese economy, the problems of electronic energy shortage confront many Chinese cities. The energy consumption of the construction proportions greatly in the total energy consumption, so does the energy consumption of the air-conditioner in the energy consumption of the construction. As the supply of the energy has been getting more and more insufficient and people increasingly care for both the warm environment and the quality of ihe air indoors, it is urgently required to Decrease the energy consumption of the air-conditioner to the most degree while keeping comfortable degree in the working reach of the air-conditioner.Generally, the energy consumption of the Central air-conditioner is composed of three parts, including the energy consumption of the cold and heat sources of the air-conditioner, the energy consumption of the water or the air-transmitting system and the energy consumption of the end equipment set of air-conditioner.It is established in this article through analysis and demonstration that the energy-conservation of Central air-conditioner should begin with the calculation of the cold and heat sources and subsequently, choose the set of cold and heat sources with proper COP value to economize the energy consumption of the cold and heat sources. Then, primarily adopts the technology of frequency conversion to realize the flow-varying working of water pump for reducing the energy consumption of water transmitting system. Moreover, utilizes VAV air-conditioner system to reduce the energy consumption of the transmition process of the wind system and subsequently, to decrease the total energy consumption of the transmition system. Meanwhile, the the end equipment set of air-conditioner should be appropriately chosen to diminish the energy consumption of the end equipments. Finally, each operating mode of the system of Central air-conditioner should be optimally controlled through automated controlled system of the air-conditioner in order to achieve the goal of reducing the total energy consumption of Central air-conditioner.The energy-conservation of Central air-conditioner system is very key to the energy-conservation of the whole building. We hope that this article can offer the masses of the employees with help and reference for their work of energy-conservation in Central air-conditioner, and make a contribution to cause of energy of our country.
