资源简介:
The DataPVT.xlsx file is a spreadsheet compiling both electrical data from a water heating system and environmental data from a hybrid photovoltaic/thermal (PV/T) system. This setup includes four photovoltaic modules, with two modules dedicated to photovoltaic (PV) generation and the other two assigned to the hybrid PV/T system. Electrical data encompass the voltage, current, and electrical power values generated by each of the four modules. For the water heating system, temperature and fluid flow data are recorded, while environmental data include ambient temperature, water temperature in the reservoir, solar irradiation, and wind speed.
The data is organized into 22 columns, each displaying the following variables:
Day – Day of data collection.
Time – Data collection time.
V1 - Voltage measured in module 1 of PV system (V).
V2 - Voltage measured in module 2 of PV system (V).
V3 - Voltage measured in module 1 of PV/T system (V).
V4 - Voltage measured in module 2 of PV/T system (V).
I1 - Current measured in module 1 of PV system (A).
I2 - Current measured in module 2 of PV system (A).
I3 - Current measured in module 1 of PV/T system (A).
I4 - Current measured in module 2 of PV/T system (A).
PPV1 - Electrical power generated by module 1 of PV (W).
PPV2 - Electrical power generated by module 2 of PV (W).
PPVT1 - Electrical power generated by module 1 of PV/T (W).
PPVT2 – Electrical power generated by module 2 of PV/T (W).
Tamb - Ambient temperature (°C).
Tboiler - Fluid temperature inside the boiler (°C).
To - Fluid temperature at the heat exchanger outlet (°C).
Tres - Water temperature in the reservatory (°C).
Ti – Fluid temperature at the heat exchanger inlet (°C).
G – Solar irradiation (W/m²).
m ̇ – Mass flow rate of the fluid at the heat exchanger outlet (l/s).
Vwind - Wind speed (m/s).
Data was collected at one-minute intervals (day and night) between August 29 and October 20, 2024. The acquisition system collects twenty samples for each variable, calculates the respective average, and associates it with the date and time when the data was collected.
DataPVT.xlsx 文件为一份汇编型电子表格,涵盖某热水系统的电气数据与混合光热(photovoltaic/thermal, PV/T)系统的环境数据。本系统配置四块光伏组件:其中两块用于纯光伏(photovoltaic, PV)发电,剩余两块搭载于混合光热PV/T系统中。电气数据包含四块组件各自产生的电压、电流与电功率数值;热水系统的记录数据涵盖温度与流体流量信息,环境数据则包括环境温度、储水容器水温、太阳辐照度与风速。
