浅圆仓空调控温试验

TEST OF TEMPERATURE-CONTROL WITH AIR CONDITIONERS IN SQUAT SILO

通过对浅圆仓安装2P、3P、6P空调,在氮气气调低氧条件下进行控温效果对比试验,发现在同样的仓房条件及相近的天气情况下,制冷量越大,降温效率越高。6P空调对仓温的控制效果最好,有效控制天数均在80%以上,而2P空调几乎无法有效控制仓温,3P空调有效控制天数只达到一半。针对南方高温高湿的广东地区,夏季高温天气持续较长,仅6P空调才能满足实际需求。

After 2P,3P,and 6P air conditioners were installed in the squat silo,a comparative experiment was carried out under the condition of low-oxygen with nitrogen-controlled atmosphere storage. It was found that air conditioner with better cooling capacity had higher cooling efficiency under the same warehouse conditions and similar weather conditions. 6P air conditioner had the best control effects on the warehouse temperature with above 80% of effective control days,while the 2P air and 3P air conditioner could not effectively control the warehouse temperature and had the half of effective control days,respectively. The results showed that in Guangdong with higher temperature and humidity,only 6P air conditioner could meet actual demand against longer hot weather in summer.
