珠江三角洲现代温室环境与能耗水平调查与实测

Research and Field Survey on Environment and Energy Consumption of Modern Greenhouse in Zhujiang Delta Area

对珠江三角洲的温室进行了调查和实测,主要目的是调查生产过程中现代温室的热湿环境情况和能耗水平,包括温室的热湿环境、全年运行时间、降温、升温以及其他温室设施的运行时间和温室的通风能耗、降温能耗、升温能耗等。调查与实测表明该地区温室环境基本满足所种植物的生长要求,但其控制能耗过高,将近达到30 kW.h/(m2.a)的电耗和4.5 kg/(m2.a)的煤耗。建议充分利用珠江三角洲的气候特点,大幅度降低能耗。

Research and field survey of modem greenhouse in Zhujiang delta were carried out to see its thermal - humidity environment and energy consumption, including the thermal - humid environment, the runtime and consumption of ventilation, thermal control all the year round. The result is that the environment of the greenhouse can basically meet the requirement of plants growth, but the energy consumption is too high, nearly 30kW/（m^2·a）of electricity and 4. 5kg/（m^2 · a）of coal is consumed. It is suggested to make good use of climate resources of that area to reduce the energy consumption
