迷你分体式热泵被提议作为一种新的改装方案，以取代太平洋西北部的阻力供暖。NREL之前已经为小型分离式系统开发了现场测试协议，以确保现场测试的一致结果。本报告侧重于开发小型分体式热泵的详细系统性能图，以便准确分析不同气候区域和住房类型的小型分体式系统的潜在好处。本报告介绍了两种微型分体式热泵的实验室测试结果。富士通12RLS和三菱FE12NA的稳态供热和制冷性能在不同压缩机和风扇转速的室外和室内温度范围内进行了测试。每个单元的循环性能也在这两种操作模式下进行了测试。这两个系统在低负载下都表现得很好，实验测试数据与制造商报告的值一致。获得了足够的数据集，以促进这两个系统未来的性能建模。
Mini-split heat pumps are being proposed as a new retrofit option to replace resistance heating in the Pacific Northwest. NREL has previously developed a field test protocol for mini-split systems to ensure consistent results from field tests. This report focuses on the development of detailed system performance maps for mini-split heat pumps so that the potential benefits of mini-split systems can be accurately analyzed for different climate regions and housing types. This report presents laboratory test results for two mini-split heat pumps. Steady-state heating and cooling performance for the Fujitsu 12RLS and Mitsubishi FE12NA was tested under a wide range of outdoor and indoor temperatures at various compressor and fan speeds. Cycling performance for each unit was also tested under both modes of operation. Both systems performed quite well under low loads and the experimental test data aligned with manufacturer reported values. Adequate datasets were attained to promote performance modeling of these two systems in the future.
