摘要
由于高电力消耗,标准电动机在世界总能源消耗中占有很大份额.在具有大量电动机,如HVAC系统的机械系统中降低能耗的替代解决方案之一是使用高效电动机.本研究中的应用介绍了一家办公场所采用高效电机替代暖通空调系统标准电机的节能、节能成本、投资回收期和减排情况.研究发现,通过将标准电机更换为高效电机,可以实现不同负载(50％、75％和100％)的可观节能值.在一年中,不同负载的总节能量分别为 122.5、120.9 和 99MWh.
Abstract
Due to high power consumption,standard motors account for a significant share of the world's total energy consumption.One of the alternative solutions to reduce energy consumption in mechanical systems with a large number of motors,such as HVAC systems,is to use high-efficiency motors.The application of high-efficiency motor energy-saving in this study introduces the energy-saving,energy-saving costs,investment payback period,and emission reduction situation of a official using high-efficiency motors instead of standard mo-tors in HVAC systems.Research has found that by replacing standard motors with high-efficiency motors,significant energy savings can be achieved for different loads(50％,75％,and 100％).In a year,the total energy savings for different loads are 122.5,120.9,and 99MWh,respectively.
