【摘要】 以系统论和相似理论为基础,分析了多元变制冷剂流量空调系统(MVRV)与单元变制冷剂流量空调系统(SVRV)空调系统在结构、物理模型、运行调节特性等方面的相似性,提出SVRV是MVRV的抽象与简化,MVRV是SVRV的扩展与延伸的理念。二者通过气液两相流体网络有机地统一,消除人们对MVRV系统开发的盲目性,为MVRV系统的优化设计、匹配选型和性能标定等指明方向。更多还原

【Abstract】 Based on the theory of system and similarity, the structure, physical model, performance of operation and adjustment and so on about single variable refrigerant volume refrigeration system (SVRV) and multiple variable refrigerant volume refrigeration system (MVRV) are studied and compared. The analysis and comparison show that SVRV is the abstraction and simplification of MVRV while MVRV is the expansion and extension of SVRV. SVRV and MVRV systems can be uniformed with gas liquid two-phase fluid network, which will be helpful for developing MVRV systems, including optimal design, selection of types and performance measurement on VRV systems.更多还原
