双联 (一拖二 )变频空调系统由于两蒸发器间各参数的相互影响 ,使得它的运行特性较复杂 ,表现极强的耦合性 .通过采用分布参数法并引入两相流理论 ,建立起以双蒸发器、电子膨胀阀、压缩机为一体的双联空调系统的热力学模型 .对双联变频空调系统稳态特性及双蒸发器间耦合关系进行仿真研究 ,为双蒸发器的优化设计、控制及节能手段的运用提供依据
Due to the mutual influence of the parameters of the two evaporators, the dual-linked (one-two-two) inverter air-condition system makes its operating characteristics more complicated and exhibits extremely strong coupling. By adopting the distributed parameter method and introducing the theory of two- The thermodynamic model of a dual air-conditioning system with dual evaporators, electronic expansion valves and compressors is taken as an example to simulate the steady-state characteristics of the dual-inverter air-conditioning system and the coupling relationship between the dual evaporators, Control and use of energy-saving measures to provide the basis
