本文详细分析了温室的热工过程,得出影响温室能耗的主要因素包括温室的太阳辐射、贯流放热量、通风换气放热量、室内土壤的地中导热量、室外气象、室内温度和作物的蒸腾作用等。通过能耗模拟软件计算了上海地区单层塑料膜温室在不同室内控制温度、不同供暖方式下的全年耗气量,结合实际调研得出,上海地区在种植常见瓜果类(番茄、黄瓜等)作物时塑料薄膜温室的全年累计耗气量约为5m3~7m3天然气/(m2温室·a)。
In this paper, the thermal process in greenhouse is analyzed in detail. The main factors affecting greenhouse energy consumption are solar greenhouse radiation, tubular heat release, ventilation heat transfer, indoor ground heat conductivity, outdoor weather, indoor temperature and crop Transpiration and so on. The energy consumption simulation software was used to calculate the annual air consumption of single-layer plastic film greenhouse in Shanghai under different indoor control temperatures and different heating methods. According to the actual investigation, it is concluded that planting common fruits and vegetables (tomato, cucumber, etc.) The total annual air consumption of plastic film greenhouse crops is about 5m3 ~ 7m3 natural gas / (m2 greenhouse · a).
