GB/T21087-2007《空气-空气能量回收装置》能效问题的讨论

GB/T21087-2007 “Air-to-Air Energy Recovery Equipment” Discussion of Energy Efficiency

通过对GB/T21087-2007《空气-空气能量回收装置》国家标准节能指标的分析和空气能量回收装置节能技术的研究,阐述了空气能量回收装置的节能理念和提高节能效果的研究方向。认为空气-空气能量回收装置的国家标准没有真实体现空气能量回收装置的节能效果,标准中还有不少概念性的误区,由于空气能量回收装置国家标准提出的能效系数不能真实反映该产品的节能状态,阻碍了空气能量回收装置节能技术的研究、提高和发展,提出应尽快修订GB/T21087-2007《空气-空气能量回收装置》国家标准,并将真正的节能指标纳入国家标准中,有利于新风行业节能技术研究和提高。

It was elaborated in this paper the energy conservation idea of air energy recovery equipment and the study direction of enhancing the energy-saving effect, through analyzing the national standard energy-saving indicators and researching the energy conservation technology of air energy recovery in GB/T21087-2007 ＂Air-to-Air Energy Recovery Equipment＂. It was believed that the national standards for air-to-air energy recovery equipment did not reflect the real energy-saving effects of the equipment, and there were many conceptual errors in the standards. Since the coefficient of energy efficiency brought up by the national standards for air energy recovery equipment cannot accurately reflect the energy-saving status of the product, the research, advancement and development of the energy-saving technology for air energy recovery devices were hampered. Therefore, the national standards of GB/T21087-2007 ＂Air-to-Air Energy Recovery Equipment＂ should be revised as soon as possible, and the actual energy-saving indicators should be included in the national standards, thus conducive to research and improvement of the energy-saving technology in the ventilation mechanical industry.
