【摘要】 【目的】研究新疆乌鲁木齐市周边地区日光温室结构优化设计方案,提升设施农业经济效益。【方法】对标准化节能日光温室的温度、湿度、地温、光照等环境因子进行数据采集,与温室热环境模拟预测软件的综合评价体系进行对比分析。【结果】(1)模拟室内外气温与实际温度变化趋势基本一致,低温误差小于0.5℃,高温误差较大,原因是输入模拟气象条件时选择了内置模式确定室外气象条件,仅提供了晴天与阴天的日最高与最低气温不够精确。(2)温室采用临时加温装备造成墙体及后屋面实测温度与预测模拟值的平均误差大于4℃。【结论】已建成新疆地区节能日光温室结构设计科学、合理,温室热环境满足越冬生产要求,温室性能模拟对日光温室性能提升,温室结构优化以及新材料的开发有着重要的意义。更多还原

【Abstract】 【Objective】The project aims to research the solar greenhouse structure and optimize design programs in areas surrounding Urumqi,thus enhancing the economic benefits of agricultural facilities.【Method】Data about the temperature,humidity,ground temperature,light intensity and other environmental factors in the energy-saving solar greenhouse were collected and compared with the comprehensive evaluation system of software for the thermal environment simulation and prediction in solar greenhouse.【Result】(1)The simulated and actual temperature of indoor and outdoor change trend is basically consistent,the low-temperature error is less than 0.5℃,the input fuzzily simulation meteorological condition caused the bigger high-temperature error.The reason that causes the error is that only built-in mode is adopted when weather condition is simulated to determine the outside temperature.Only informing the highest and lowest temperature in sunning or cloudy days can not gurantee the accuracy.(2)Because the greenhouse uses the temporary heating equipment,therefore the wall and the roof’s actual temperature and the forecast simulation value average error is greater than 4℃.【Conclusion】Has completed the solar greenhouse structural design of scientific and reasonable,to meet the production requirements of winter.Greenhouse thermal environment simulation software has important significance on the performance of solar greenhouse structure optimization and upgrading,development of new materials in region of Urumqi,Xinjiang.更多还原
