The present study exposes an economical and easy-to-use system to assess the heat transfer in building envelopes by determining the U-value. Nowadays these systems require long wires and a host to collect and process the data. In this work, a multi-point system for simultaneous heat flux measurement has been proposed. The aim is to reduce the long measurement time and the cost of thermal isolation evaluations in large buildings. The system proposed consists of a low-cost 3D-printed heat flux sensor integrated with a LoRa transceiver and two temperature sensors. The heat flux (HF) sensor was compared and calibrated with a commercial HF sensor from the Fluxteq brand.
本研究提出了一种经济且易于使用的系统，通过确定 U 值来评估建筑围护结构的传热。如今，这些系统需要长导线和一个主机来收集和处理数据。在这项工作中，提出了一种用于同时测量热通量的多点系统。其目的是减少大型建筑物中热隔离评估的长测量时间和成本。所提出的系统由低成本的 3D 打印热通量传感器与 LoRa 收发器和两个温度传感器集成而成。对热通量 (HF) 传感器与 Fluxteq 品牌的商用 HF 传感器进行了比较和校准。
