摘要
随着我国农业产业化结构的升级发展,现代温室作为农业的一种新型生产方式,已成为未来发展的一个方向。在农业农村部提出相关绿色设施农业规划后,近年来,其建造面积与使用规模迅速增长,发展趋势为智能化、自动化、节能低碳化。但实际运行中,其生产运营成本往往较高,能源消耗是运营中最大的成本。在建筑能耗中暖通空调系统耗能比例接近60%,因此降低空调系统能耗对温室运行费用的降低具有重要意义。本文以某项目现代温室为研究对象,在空调设计中创新地采用多能互补的能源系统,以地热能、空气能、太阳能为一体的清洁能源形式进行整合,同时耦合低温跨季储能技术,全方位保证温室内科研项目的顺利开展。在实际运行后,对比传统温室空调系统,能耗更低,实现了现代温室的低成本运行,且环保效益显著,节约199.5 t标准煤/年,减排CO_(2)552.6 t/年,减排SO_(2)0.28 t/年,减排NOx 1.79 t/年,减排烟尘2.2 t/年。此多能互补与低温跨季储能系统的实施为农作物大棚能源管理和节能运营提供了一个可借鉴的新标杆,契合整体项目低碳、节能、可再生的定位,可为我国北方地区现代温室的空调系统提供技术参考。
With the upgrading and development of China’s agricultural industrialization structure,modern greenhouses,as a new production method in agriculture,have become a direction for future development.After the Ministry of Agriculture and Rural Affairs proposed relevant green facility agriculture plans,their construction area and usage scale have rapidly increased in recent years,and the development trend is towards intelligence,automation,energy conservation,and low-carbon.However,in actual operation,the production and operation costs are often high,and energy consumption is the largest cost in operation.The energy consumption of HVAC systems accounts for nearly 60%of building energy consumption,therefore,reducing the energy consumption of HVAC systems is of great significance for reducing greenhouse operating costs.This article takes a modern greenhouse project as the research object,innovatively adopting a multi energy complementary energy system in air conditioning design,integrating geothermal energy,air energy,and solar energy as a clean energy form,while coupling low-temperature cross season energy storage technology,to ensure the smooth development of scientific research projects in the greenhouse in all aspects.After actual operation,compared with traditional greenhouse air conditioning systems,the energy consumption is lower,achieving low-cost operation of modern greenhouses and significant environmental benefits,it saves 199.5 tons of standard coal per year,reduces CO_(2) emissions by 552.6 tons per year,SO_(2) emissions by 0.28 tons per year,NOx emissions by 1.79 tons per year,and smoke emissions by 2.2 tons per year.The implementation of this multi energy complementary and low-temperature cross season energy storage system provides a new benchmark for energy management and energy-saving operation in crop greenhouses,which is in line with the overall project’s low-carbon,energy-saving,and renewable positioning,it can provide technical reference for modern greenhouse air conditioning systems in northern China.
