基于EnergyPlus的保育猪舍冬季温度与能耗模拟研究

Simulation of Temperature and Energy Consumption of a Weaner House in Winter Based on EnergyPlus

保育猪刚经历断奶应激,对低温很敏感,保育猪舍的温度环境直接影响其发病率、成活率和生长性能。本文应用建筑能耗模拟软件EnergyPlus对中国南方地区一栋典型结构、冬季采用热水地暖系统的保育猪舍温度和能耗进行了模拟和分析。冬季采暖时EnergyPlus对保温猪舍舍内温度的模拟结果与实际测量值对比结果为决定系数R2=0.81,均方根误差RMSE=0.94,最大差值为2.14℃,平均差值为0.76℃;整个冬季采暖煤耗量模拟结果与实际使用量的误差为7.9%。结果表明:EnergyPlus可以模拟该保育舍的温度及能耗。

Environmental temperature inside weaner houses is very importa nt for weaners＇ health and growth performance since the weaners have just suffered from ablactation hyperirritability and are very sensitive to low temperature. In this study, the building energy simulation tool-EnergyPlus was applied to simulate temperature and energy consumption of a typical weaner house in Eastern China. The floor of the weaner house was half-slatted with hot-water heating system under the half-solid area. The results of comparison between simulated and measured temperate in winter heating season were： coefficient of determination RE was 0.81; root-mean-square error RMSE was 0.94; the maximum difference was 2.14℃ and the mean difference was 0.76℃. The difference between simulated and recorded coal consumption in the studied winter was 7.9%. The resuhs indicated that using EnergyPlus was acceptable for dynamic simulation of weaner house temperature and energy consumption.
