The various types of buildings, the extensive use of advanced equipment and related auxiliary equipment, central air-conditioning system made of building technology has become an important symbol of one of modern architecture to create a comfortable and efficient working and living environment are essential infrastructure. This energy conservation status of the central air conditioning, energy-saving measures were discussed. More exciting Information "> HC HVAC Network Energy saving of air conditioning We all know, energy is essential for human survival and social development of the material basis of energy saving is the common mission of mankind. , "Energy conservation" has been a basic state policy of China, adhere to the "conservation and development simultaneously, giving priority to conservation" has been a long-term energy conservation policy of our country. Vigorously promote energy-saving technological progress, dramatically improving energy efficiency, improve social and economic benefits, is that we face in promoting energy-saving changes to the national economy is an important task, two in 2009 to energy-saving theme is carried out, and the agency and other related departments have developed a related energy-saving policies, such as air conditioning, Water Heater Improve energy efficiency, heat pump technology to enhance energy efficiency are reflected even in China has become an issue of global concern. HVAC specific to our industry, air conditioning, water heater, heat pump technology and energy saving products are essential raw materials to energy saving. Moreover, the energy consumption in our buildings energy consumption accounts for about 1 / 3, central air conditioning system energy consumption accounts for 65% of China's building energy consumption, this is a very alarming figure. Air conditioning system for reducing the energy consumption of the whole building is critical. To this end, the central air-conditioning energy saving control of product development has become a central air-conditioning business for each major task, and only then continue to adapt to market demand, companies can become bigger and stronger. How to understand the energy? Energy conservation, saving energy is by definition is the rational use of energy, and enhancing energy efficiency. The so-called Building energy efficiency Is living in comfort requirements are met under the precondition of the use of thermal insulation at the building of new wall materials and high-efficiency ratio of Heating Air-conditioning to save energy, reduce energy consumption, improve energy efficiency purposes. Clearly the central air-conditioning energy saving energy saving direct impact on the building. Central air conditioning system for energy conservation is concerned, one is from the design of the system itself, considering the overall energy consumption; on the other hand, in the use and maintenance of the process, as required to manage, so the system can be extended life can also reduce unnecessary materials, energy waste. So how to maximize energy efficiency central air conditioning, except that it itself, its end product that is Fan Coil Unit , Fans, compressors and other central air-conditioning end products require maximum energy efficiency. Separately from air-conditioning, fans start of energy? 1, the current air conditioning system design, energy saving measures (1) building equipment with automatic control technology to control air-conditioning terminal units In Intelligent Building Premises equipment commonly used in automatic control systems, central air conditioning system at the end of the new fan, back fan, variable air volume fan, fan coil units and other devices to monitor and use state of the "fine" control, in order to achieve conservation of energy. It does this by DDC (Direct Digital Controller) controller will detect the relevant value for PID (proportional, integral, differential) operator, to realize the PID control of the equipment, up to the energy saving effect. This kind of air-conditioning terminal equipment control can be saving 10% -15%, as can not be achieved on Air Conditioning Station and the air conditioning system intelligent control, therefore, energy-saving effect is not significant. This typical energy-saving control technologies products and manufacturers are: A, Honeywell EXCEL5000 building services automation system; B, United States, Johnson's building automation systems; C, Siemens S600 peak system. Air terminal device is controlled by the Building Automation System (BAS), the main characteristics of these devices are implemented energy-saving air-conditioning terminal equipment control, and dynamic variable flow operation of the energy saving control system to create a more favorable external conditions. (2) to adopt a common Inverter Central air conditioning system to control pumps and fans Central air conditioning system to reduce energy waste, should adopt a common frequency converter to control the air conditioning system of pumps and fans, through the supply and return water pressure or temperature of the collection, on the water pump and fan PID regulator in order to save energy effect. This control method usually saves such as pumps and fan motor drive system of electric energy by about 20% up to 30%. This energy-saving control technology manufacturers and typical products: A, Schneider Electric (SchneiderElectric), representative products Ahivar38 series inverter asynchronous motor; B, Germany's Siemens (SIEMENS), representative products are general purpose inverter MICROMASTER440 products.
