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.

A water loop variable refrigerant flow (WLVRF) air-conditioning system is designed to be applied in large-scale buildings in northern China.The system is energy saving and it is an integrated system consisting of a variable refrigerant flow (VRF) air-conditioning unit,a water loop and an air source heat pump.The water loop transports energy among different regions in the buildings instead of refrigerant pipes,decreasing the scale of the VRF air-conditioning unit and improving the performance.Previous models for refrigerants and building loads are cited in this investigation.Mathematical models of major equipment and other elements of the system are established using the lumped parameter method based on the DATAFIT software and the MATLAB software.The performance of the WLVRF system is simulated.The initial investments and the running costs are calculated based on the results of market research.Finally,a contrast is carried out between the WLVRF system and the traditional VRF system.The results show that the WLVRF system has a better working condition and lower running costs than the traditional VRF system.
