华南地区高大平房仓横向通风应用试验

Application of Horizontal Ventilation in Large Size Horizontal Warehouse in Southern China

本文研究在条件相同的高大平房仓内分别安装横向和竖向通风系统,同时进行通风降温试验。通过试验发现,横向通风也可以达到通风目的,从粮堆上层到下层降温的均匀性较好,但远端粮温下降缓慢,且所需通风时间较长。

This paper studies the installation of horizontal and vertical ventilation systems in tall bungalows with the same conditions,and carries out ventilation cooling tests at the same time.It is found that the horizontal ventilation can also achieve the purpose of ventilation.The uniformity of cooling from the upper layer to the lower layer of the grain heap is better,but the temperature of the distal grain decreases slowly and the ventilation time is longer.
