基于Simulink的双压缩机空调分段除霜模拟

Simulation of sectional defrosting of dual compressor air conditioning based on simulink

针对寒冷及严寒地区空调制热运行下除霜展开研究,设计一种双压缩机热气旁通式分段除霜空调并进行仿真模拟。结果表明,该模型在寒冷地区的气候条件下正常运行,保证室内温度趋于稳定,并能够分段进行有效除霜。变制冷剂流量多联式空调系统(新型VRV空调系统)适用于寒冷地区冬季的供暖,为新型VRV空调供暖在寒冷地区的应用提供参考。

In view of the research on defrosting of air conditioner heating operation in cold and severe cold areas,a dual-compressor hot air bypass segmented defrosting air conditioner was designed and simulated.The results show that the model works normally under the cold climate conditions,and can ensure that the indoor temperature tends to be stable,and effective defrosting can be carried out in sections.The new VRV air conditioning system is suitable for winter heating in cold areas,which provides a reference for the application of new VRV air conditioning heating in cold areas.
