喷气增焓技术对多联机制冷性能影响分析

Effect of Enthalpy Enthalpy Enhancement Technology on Cooling Performance of Multiplex Machine

为了使多联式空调机组在制冷工况时制冷性能更佳,本文在机组开启喷气的情况下,名义制冷全开负荷占比98.13%,制冷能力比普通多联机高13.46%。高温制冷工况下,全开负荷开喷气能力占比89.1%,比常规多联机提升13.17%。制冷能力可提升10%~15%。开喷气的情况下,系统过冷度比不开喷气高3~5℃,可降低室内侧噪音,提高用户使用效果。

In order to improve the refrigeration performance of multi-connected air-conditioning units under refrigeration conditions,the nominal refrigeration full-open load accounts for 98.13%under the condition of unit opening jet,and the refrigeration capacity is 13.46%higher than that of common multi-connected air-conditioning units.Under high temperature refrigeration conditions,the capacity of full open-load start-up jet accounts for 89.1%,which is 13.17%higher than that of conventional multi-line.Refrigeration capacity can be increased by 10%-15%.Under the condition of open jet,the supercooling degree of the system is 3-5℃higher than that without jet,which can reduce the indoor side noise and improve the user’s use effect.
