Comprehensive Building a Central Air-Conditioning Analysis of the Economic Benefits of Energy-Saving Measures

通过对具体工程实例分析和论述,得出中央空调的节能可以通过提高制冷主机冷凝器的换热效率来提高主机在常年运行时高效节能,并利用冷凝热回收技术来回收原来冷却塔带走的热量,这样既可得到免费热水,又可以减少冷却塔的排放热量,利用新风全热换热器来回收排风中的冷量,并通过空调自动控制系统,在中央空调各种不同工况时,进行优化控制,实现整个系统的节能运行,从而达到降低整个中央空调系统能耗的目的。

Through specific examples of projects and expositions that the central air-conditioning refrigeration energy saving can be achieved by improving the efficiency of mainframe condenser heat exchangers in the years to improve mainframe running high efficiency and energy saving, and use condensing heat recovery technology to recover the original cooling tower heat away This not only receive free hot water, cooling tower will reduce emissions of heat, wind-wide use of the new heat exchanger to heat recovery ventilation in the cold, and through air-conditioning control system, the central air-conditioning in all kinds of different conditions,, optimal control and realize the energy-saving operation of the entire system, so as to achieve the central air-conditioning system to reduce energy consumption purposes.
