空调热泵设备性能测量与评价:从稳态到实际
Performance measurement of air conditioning heat pump units: From steady conditions to actual operation
【摘要】 空调热泵装置的制冷(热)能力及能效是评价其性能的主要指标。在实验室稳态工况性能测量中,为体现空调热泵部分负荷性能的提升,性能评价经历了从“点”评价到季节性能评价的过程,但其本质都是给定热源侧和使用侧工况以及指定压缩机和风机运行状态下的稳态运行参数。随着空调热泵装置控制水平的发展,为进一步空调热泵装置的自动控制特征与品调控质,综述了国内外关于基于变化负荷性能测量的方法,包括静态补偿法(房间固定负荷)和动态补偿法(虚拟建筑负荷),本质是将虚拟的空调热湿负荷施加到实验室室内侧,并要求空调热泵装置根据室内的负荷利用自动控制技术将室内调节到设定温度,在此期间获得机组的性能。旨在为建立在实验室模拟空调热泵装置实际运行性能的测量方案提供参考或依据。
【Abstract】 The cooling(heating) capacity and energy efficiency of air conditioning heat pump devices are the main indicators for evaluating their performance. In laboratory steady-state performance measurement, in order to reflect the improvement of partial load performance of air conditioning heat pumps, performance evaluation has gone through a process from "point" evaluation to seasonal performance evaluation, but its essence is the steadystate operating parameters under given heat source side and usage side conditions, as well as specified compressor and fan operating conditions. With the development of the control level of air conditioning and heat pump devices, in order to further improve the automatic control characteristics and quality control of air conditioning and heat pump devices, reviews the methods for measuring performance based on variable loads at home and abroad, including static compensation method(chamber induced load) and dynamic compensation method(virtual building load). Essentially, virtual air conditioning heat and humidity load is applied to the inside of the laboratory room, And it is required that the air conditioning and heat pump device use automatic control technology to adjust the indoor temperature to the set temperature based on the indoor load, in order to obtain the performance of the unit during this period. Aims to provide reference or basis for establishing a measurement scheme for simulating the actual operating performance of air conditioning heat pump devices in the laboratory.
