鸭梨机械冷藏库制冷装置属于中压设备,制冷压缩机、附属设备及管道均在一定压力下工作,故有一定的危险性。制冷剂(氨)具有毒性,并能燃烧和爆炸。氨液溅到皮肤上会引起冻伤、烧伤。氨气能刺激人的眼睛及呼吸器官。当空气中单位体积含量达0.5～0.6%时,半小时即可引起人体中毒;含量达15～25%时,遇明火会引起爆炸。目前,梨产区一些小型机械冷藏库已投产使用,为保证制冷装
Yali mechanical refrigerator refrigeration unit belongs to the medium-voltage equipment, refrigeration compressors, ancillary equipment and pipes are under pressure to work, so there is a certain degree of danger. Refrigerants (ammonia) are toxic and can burn and explode. Ammonia splashing on the skin can cause frostbite and burns. Ammonia can stimulate people’s eyes and respiratory organs. When the air volume content of 0.5 to 0.6% per unit, half an hour can cause human poisoning; content of 15 ~ 25%, the event of fire will cause an explosion. At present, some small mechanical refrigerators in the pear producing area have been put into operation, in order to ensure refrigeration equipment
