本文基于TRNSYS软件分别建立了空气源热泵的变水流量(VWV)和定水流量(CWV)模型。该模型可以对系统各部件的运行特性进行模拟。通过模拟仿真,对系统在VWV与CWV控制策略下的性能参数进行了计算与分析。结果表明,与CWV系统相比,VWV系统室温波动较小,并且能够节能10.3%。本文所建立的模型及所应用的VWV系统节能分析方法,为VWV系统的应用及推广提供了理论依据。
Based on the TRNSYS software, the variable water flow (VWV) and constant water flow (CWV) models of air source heat pump are established respectively. The model can simulate the operating characteristics of various components of the system. Through the simulation, the performance parameters of the system under VWV and CWV control strategy are calculated and analyzed. The results show that compared with the CWV system, the VWV system is less volatile at room temperature and can save 10.3% energy. The model established in this paper and the energy-saving analysis method of VWV system provided a theoretical basis for the application and popularization of VWV system.
