Building Surface Temperature Measurement System

建筑物约占加拿大总能源消耗的29%和温室气体排放的22%，其中三分之二归因于空间供暖和制冷需求。使用被动式热存储，主要是建筑集成相变材料（PCM），可以将满足这些需求所需的能源减少20- 30%。虽然这种减少是显着的，但在这些材料可以安全地集成到传统组件之前，仍然需要进行大量的研究。为了解决这一差距，有必要改善建筑物表面温度的可用数据，包括房间表面温度的趋势和空间分布。为了支持这种对更好数据的需求，卡尔顿大学高级建筑围护结构研究中心（CABER）主任兼PI Cruickshank博士开发了两个全尺寸的全仪表测试室，每个测量3 m x 3 m x 3 m，具有可更换的内部面板。目前正在建造的两个室是相同的，可以完成比较测试（例如，一个是典型的建筑材料，另一个是建筑集成PCM面板）。然而，这些测试室目前还没有配备详细或真实的时间监测房间中的空间表面温度分布。由于这些数据对于推进最新技术水平和支持Cruickshank博士的NSERC Discovery研究至关重要，她通过NSERC RTI计划申请76，310美元，用于购买两个独特的定制设计的表面温度测量系统，安装在CABER内的两个测试室中。该系统由Viper Imaging设计和提供，每个系统都使用一个FLIR A70相机，带有95°透镜，连接到平移和倾斜系统，允许使用单个相机完成整个空间的完整扫描，获得测试箱每个10 cm x 10 cm区域的温度读数。与相机耦合的是一个高精度红外温度计，它将用于红外相机的连续校准，提高结果的准确性。这两台相机将反馈到一个运行ViperTrack的计算机工作站，ViperTrack是一种用于编译和分析红外相机数据的软件，将用于提供详细的数据集，用于分析和计算机模型验证。除了改进PCM的实验和建模方法外，共同申请人奥布莱恩博士和Gunay博士还将在他们自己的研究中广泛使用这种设备，分别侧重于不断变化的建筑条件下居住者舒适度的影响和自适应建筑控制对空间内能源使用的影响。 拟议的设备对于上述研究的成功以及加拿大应对气候变化的新工具和方法的开发至关重要。这是特别真实和及时的，因为到2025年需要大幅减少能源和排放目标，以实现加拿大政府的2030年目标。

Buildings account for approximately 29% of Canada's total energy consumption and 22% of greenhouse gas emissions, two-thirds of which are attributed to space heating and cooling demands. The use of passive thermal storage, primarily with building integrated phase change materials (PCMs), can reduce the energy required to meet these demands by 20-30%. Although this decrease is significant, much research is still required before these materials can be safely integrated into traditional assemblies. To address this gap, it is necessary to improve the available data for building surface temperatures, including the trends and spatial distribution of a room's surface temperature. To support this need for better data, Dr. Cruickshank, Director and PI of the Carleton University Centre for Advanced Building Envelope Research (CABER), has developed two full-scale fully instrumented test chambers, each measuring 3 m x 3 m x 3 m, with replaceable interior panels. The two chambers, currently under construction, are identical, allowing for comparative tests to be completed (e.g., typical construction materials in one and building integrated PCMs panels in the other). These tests chambers, however, are not currently equipped to monitor the spatial surface temperature distribution in the room in detail or real time. As these data are critical to advance the state of the art and support Dr. Cruickshank's NSERC Discovery research, she is requesting $76,310 through the NSERC RTI program to purchase two unique, custom designed surface temperature measurement systems, to be installed in each of the two test chambers within CABER. The systems, designed and supplied by Viper Imaging, each utilize a FLIR A70 camera with a 95° lens, attached to a pan and tilt system, allowing for a complete sweep of the entire space to be completed using a single camera, obtaining temperate readings for each 10 cm x 10 cm area of the test chamber. Coupled to the camera is a high accuracy IR thermometer, which will be used for continuous calibration of the IR camera, improving the accuracy of results. Both cameras will feed back to a single computer workstation running ViperTrack, a software for compiling and analyzing IR camera data, which will be utilized to provide a detailed data set for analysis and computer model validation. In addition to improving the experimental and modelling methods for PCMs, co-applicants Drs. O'Brien and Gunay will make extensive use of this equipment within their own research, which focuses on the impact of occupant comfort under changing building conditions and adaptive building controls on the energy use within a space, respectively. The proposed equipment is critical to the success of the aforementioned research and the development of new tools and methods in Canada's battle against climate change. This is especially true and timely, given the substantial energy and emission target reductions required by 2025 to meet the 2030 objectives of the Canadian government.
