For the heat transition and integration of renewable energies, systems with components (heat pumps, heat exchangers, absorbers, collectors, etc.) are required that achieve high efficiencies with low temperature differences following the low-ex principle. To achieve these efficiencies, the behavior of the components must be precisely known. Measurement under laboratory conditions is therefore a central prerequisite for the research and development of such systems. The task of the testbed is to enable this precise measurement of components. This provides data for precise modeling and simulation of not only the static but also the dynamic behavior of the components. These models then feed back into the research of novel systems through hardware-in-the-loop simulation and validation, again using the testbed. Due to insufficiently stable conditions and a lack of control options, the acquisition of measurement data and model validation of this quality is not possible through testing in the context of prototypes and demonstrators outside of a laboratory testbed. The special feature of the testbed is that three media streams are available: 1. a conditioned air stream with high power application for heat and moisture transfer (up to 25 kW), 2. a conditioned liquid stream also with high power transfer (up to 25 kW) and 3. a conditioned air stream for limited power application to simulate a two indoor or outdoor climate (up to 5 kW). The measurements follow three use cases: 1. heat and moisture exchange in building services components, 2. measurement of humid air and air collectors, and 3. measurement of airflow for indoor conditioning. One focus of the unit will be to investigate novel system components based on open absorption and air-to-air systems that integrate heat pumps. This includes the use of solar radiation as a heat source with latent heat transport as humidity and other nanofluid-based methods to establish lower-loss transport principles. In addition, the device will enable experimental research on indoor comfort in the context of such novel systems as well as conventional building services systems. Finally, the device provides opportunities of data acquisition for data-driven prediction models generated by machine learning (ML) that represent complex thermodynamic processes for further simulation and planning in an agile manner following the paradigm of component-based ML.

对于可再生能源的热转换和集成，系统的组件（热泵，热交换器，吸收器，收集器等）需要在遵循低Ex原理的情况下以低温差实现高效率。为了实现这些效率，必须精确地知道组件的行为。因此，在实验室条件下进行测量是研究和开发此类系统的核心先决条件。测试台的任务是实现对组件的精确测量。这不仅为组件的静态行为而且为组件的动态行为的精确建模和仿真提供了数据。然后，这些模型通过硬件在环仿真和验证反馈到新系统的研究中，再次使用测试平台。由于不够稳定的条件和缺乏控制选项，无法通过在实验室测试台之外的原型和演示环境中进行测试来获取测量数据和模型验证。该试验台的特点是有三种媒体流可用：1.具有用于热和湿气传递的高功率应用（高达25kW）的经调节的空气流，2.也具有高功率传递（高达25kW）的经调节的液体流，以及3.用于有限功率应用的空调气流，以模拟两个室内或室外气候（高达5 kW）。测量遵循三个用例：1.建筑服务部件中的热和湿气交换，2.测量湿空气和空气收集器，以及3.测量室内空调的气流。该单位的一个重点将是研究基于开放式吸收和集成热泵的空气对空气系统的新型系统组件。这包括使用太阳辐射作为热源，潜热传输作为湿度和其他基于纳米流体的方法来建立低损耗传输原理。此外，该设备将使实验研究的室内舒适度的背景下，这种新的系统以及传统的建筑服务系统。最后，该设备为机器学习（ML）生成的数据驱动的预测模型提供了数据采集的机会，这些模型代表了复杂的热力学过程，以便按照基于组件的ML范式以敏捷的方式进行进一步的模拟和规划。
