我们开发了一个详细的稳态系统模型，以模拟集成五区可变制冷剂流量（VRF）热泵系统的性能。该系统是多功能的，能够进行空间冷却、空间加热、空间冷却和水加热组合以及专用水加热。根据设备系统模型产生的数据，开发了各种方法来绘制每种模式下的VRF性能。性能图用于TRNSYS年度能源模拟。 使用TRNSYS，我们成功地在5种气候条件下的5区住宅中设置并运行了多个分体式、VRF热泵和除湿器组合的案例，这些气候条件控制室内干球温度和相对湿度。我们比较了VRF热泵与基准中央空气源热泵的计算能耗，以及电热水和独立除湿器。此外，我们还研究了VRF热泵的多种控制方案，即:。 e、 开/关控制、可变室内空气流量，以及使用不同的区域温度设置计划等。对多种情况下的节能进行了评估。引文:美国丹佛市ASHRAE会议论文

We developed a detailed steady-state system model, to simulate the performance of an integrated five-zone Variable Refrigerant Flow (VRF)heat pump system. The system is multi-functional, capable of space cooling, space heating, combined space cooling and water heating, and dedicated water heating. Methods were developed to map the VRF performance in each mode, based on the data produced by the equipment system model. The performance maps were used in TRNSYS annual energy simulations. Using TRNSYS, we have successfully setup and run cases for a multiple-split, VRF heat pump and dehumidifier combination in 5-zone houses in 5 climates that control indoor dry-bulb temperature and relative humidity. We compared the calculated energy consumptions for the VRF heat pump against that of a baseline central air source heat pump, coupled with electric water heating and standalone dehumidifiers. In addition, we investigated multiple control scenarios for the VRF heat pump, i.e. on/off control, variable indoor air flow rate, and using different zone temperature setting schedules, etc. The energy savings for the multiple scenarios were assessed.
