商超用CO_2制冷系统能效测试及评价方法
|
摘要
本文以我国商超制冷系统中应用的HFC/HFO-CO_2复叠式制冷系统为研究对象,参考国家标准中对传统商超制冷系统的分析评价体系,对商超用CO_2制冷系统能效测试及评价方法进行分析,提出相应的能效测试和评价方法,为实际CO_2商超制冷系统测试评价工作以及相应的提效等节能管理工作提供理论依据和技术指导。
Taking the HFC/HFO-CO_2 cascade refrigeration system applied in commercial refrigeration system in China as the research object, referring to the analysis and evaluation system of traditional commercial refrigeration system in national standards, the energy efficiency test and evaluation method of commercial CO_2 refrigeration system are analyzed. And the corresponding energy efficiency test and evaluation methods are put forward, which can be used to test and to evaluate the actual commercial refrigeration system, in order to improve its efficiency. It provides theoretical basis and technical guidance for energy-saving management of commercial CO_2 refrigeration system.
