=====================================

it is inevitable that the environment temperature of PLC and other temperature converter devices exceeds the allowable value. If the environment temperature of PLC can not be limited below its allowable value, the following methods should be adopted to reduce the environment temperature so that it is within the allowable temperature. According to the engineering experience formula, to reduce the temperature rise in the electric control cabinet, it is necessary to increase the size of the distribution cabinet or increase the air flow rate in the distribution cabinet. It is not economical to increase the size of distribution cabinet, so the method of increasing the ventilation capacity of cooling fan is generally adopted. When installing the cooling fan in the electric control cabinet, the large heat generating device should be as close as possible to the cold air inlet to improve the heat dissipation efficiency, and try to avoid installing PLC on the top of the heat source because the PLC control system large heating devices lead to an abnormal rise in the temperature of the setting place, you can use the installation of ventilation and ventilation equipment to discharge the heat of the electric control cabinet to the outside, or the installation of cold room devices forced to reduce the setting of the environment temperature.

獨守一份靜謐的時光，做一個自私的幸福者。為鳥的翅膀掠過的天空，回憶流動的風;為小蟲爬過光滑的樹葉，重溫那些清涼。愛在不言中，思念是蝴蝶的翅膀，在莊周的夢里翩翩起舞;春心托給杜鵑，在靜謐的山谷夜夜啼鳴。如珠的眼淚，悄悄閃爍在月華中。似煙的玉氣，久久縈繞在暖陽里�？蓯鄣那帏B啊，你飛去哪里?殷勤顧盼的眼神，怎能冷落蓬山的劉郎?守望一份幸福，在每一個日出日落，為遠方的人默默祈禱。
