Measurement of temperatures, HVAC system values and weather-station readings for single-floor industrial building in Croatia

This data is measurements for temperature inside building, together with measurements from HVAC system (radiator based) and reading from outside weather station. Data was used for estimation of parameters of thermodynamic model of building and HVAC system. Outside temperature, heat-flow from HVAC system and Solar radiation were used for inputs, while inside temperatures are outputs of model. This is industrial building with offices and production space. Office part is in two-floors and is equipped with separate heating system based on floor-heating. Rooms are equipped with independent thermostats and there are no measurements in them. During winter, temperature in offices is set between 20 and 24 °C, depending if office is occupied. Production space is separated in four zones: Assembly (largest, 24x16m), Entry (8x8), Mechanical preparation (8x8) and Warehouse (8x16). Production is space is made from concrete construction with structural insulating panel (SIP). There are several windows on all spaces, made from triple-glazing. There are one small door for personnel and one big doors for loading/unloading, both on Entry outside wall. There are several doors between space, which are closed most of the time. There is one small door connecting Assembly with office part of the building. HVAC system for production consist of one 35kW hot-water boiler. There is a pump and three-way valve that mixes water to setpoint temperature (usually around 60 °C). Water is then supplied to ceiling radiators in spaces. For each space, there is an open-close valve, controlled by PLC (simple hysteresis ON-OFF controller). Outside, there is weather-station Davies, model Vantage Pro2. Data is following: Date Time Outside temperature (HVAC) °C (this is sensor on one wall without cover, so it is affected by Sun and is not reliable) Assembly temperature °C Entry temperature °C Mechanical preparation temperature °C Warehouse temperature °C Flow m3/h (of supply water) Supply water temperature °C Return water temperature °C Assembly valve state (0 is closed, 1 is open) Entry valve state Mechanical preparation valve state Warehouse valve state Assembly setpoint temperature °C Entry setpoint temperature °C Mechanical preparation setpoint temperature °C Warehouse setpoint temperature °C Supply water setpoint temperature °C Outside temperature (weather station) °C (this is reliable outside temperature) Outside humidity % Wind speed m/s Solar radiation W/m2 Measurements are in 15 minute interval (if it was more frequent, it was averaged to 15 minutes). There are two breaks in data, at 11.1.2019 16:15:00 and at 24.1.2019 17:30:00. Data also include thermodynamic model that was used with this data (initial model and resulting optimized model).

本数据集涵盖建筑内部温度、基于散热器的暖通空调 (Heating, Ventilation and Air Conditioning, HVAC) 系统实测数据，以及外部气象站观测数据。该数据集曾用于建筑与暖通空调系统热力学模型的参数估计任务，其中模型输入项为室外温度、暖通空调系统热流量与太阳辐射，模型输出为各区域室内温度。
该建筑为兼具办公与生产功能的工业建筑。办公区域共两层，配备独立的地板采暖系统，各房间设有独立温控器，但未采集其内部温度数据。冬季办公区域的温度设定值介于20至24℃之间，具体数值取决于办公区域是否处于使用状态。
生产区域划分为四个功能分区：装配区（面积最大，尺寸为24×16m）、入口区（8×8m）、机械准备区（8×8m）与仓储区（8×16m）。生产区域采用混凝土结构搭配结构保温板 (Structural Insulated Panel, SIP) 建造。所有区域均设有三层中空玻璃窗，入口区外墙设置1扇人员通行小门与1扇用于货物装卸的大门。区域之间设有多扇隔断门，日常多数时间处于关闭状态；另有1扇小门连通装配区与办公区域。
生产区域的暖通空调系统配备1台35kW热水锅炉，配套水泵与三通调节阀，用于将供水温度调节至设定值（通常约60℃）。热水随后被输送至各分区的吊顶散热器，每个分区均配有由可编程逻辑控制器 (Programmable Logic Controller, PLC) 控制的开关阀，采用简单的滞环开关控制器进行调节。
室外搭载型号为Vantage Pro2的Davies气象站。
