一、概述为了防止冷库地坪冻鼓,影响生产和操作,一般低温冷库的地坪均需作防冻处理。目前我国冷库地坪防冻的方法有机械通风防冻、自然通风防冻、油加温防冻和底层地坪架空防冻等。在以上这些防冻方法中,除机械通风防冻在炎热地区,夏季可作氨压机房的防暑降温用外,其余均是将冷间传入地下的冷量通过某种媒质的作用,散入到周围环境中去,因而这一低温冷源并未能得到很好的利用。大家知道,在冷库制冷系统压缩循环 First, an overview In order to prevent cold floor floor freeze drum, affecting production and operation, the general floor of cold storage are required for antifreeze treatment. At present, China’s cold floor antifreeze methods are mechanical ventilation antifreeze, natural ventilation antifreeze, antifreeze oil heating and ground floor antifreeze. In these antifreeze methods, in addition to mechanical ventilation antifreeze in hot areas, the summer can be used ammonia prevention room cooling prevention, the rest are the cold into the ground through the role of a medium of cooling capacity, into The surrounding environment, so this low-temperature cold source has not been well used. We all know that in the cold storage refrigeration system compression cycle
