首先,设计了一种水环多联式集成空调(WLVRF)系统.该系统节能环保,是多联机、水环路和空气源热泵的集成产物,适用于北方大型建筑中.其中,水环路替代制冷剂管路承担了建筑各区域间能量转移的任务,从而减小了单台多联机的规模,提高了机组效率.然后,应用现有的制冷剂和建筑负荷模型,以DATAFIT和MATLAB软件为工具,建立了该系统中各主要组成设备及其他组件的集总参数法数学模型,并模拟了系统性能.通过市场调查,计算出系统的初始投资和运行费.最后,将WLVRF系统和传统多联机(VRF)系统进行比较,结果显示WLVRF系统具有更优良的运行工况,运行费用更低.
First of all, a water ring multi-integrated air conditioning (WLVRF) system is designed, which is energy saving and environmental friendly and is an integrated product of multi-line, water loop and air source heat pumps and is suitable for large northern buildings. The alternative refrigerant pipeline undertakes the task of energy transfer between various regions of the building, thus reducing the size of a single multi-line and increasing the unit efficiency.Then, using the existing refrigerant and building load models, using DATAFIT and MATLAB software As a tool, a mathematical model of the lumped parameter method of the main components and other components of the system is established and the system performance is simulated, and the initial investment and operating cost of the system are calculated through market research.Finally, the WLVRF system and the traditional Multi-line (VRF) system for comparison, the results show that WLVRF system has more excellent operating conditions, lower operating costs.
