Ventilation pipe is a kind of municipal infrastructure which can make the air circulate and reduce the concentration of harmful gas. It is also the mainstream cooling method in factories and workshops at present. What details should be paid attention to when using the ventilation pipe to cool down? According to the long-term engineering experience, the editor has found the following four points that must be paid attention to:
Jinan ventilation duct
1、 Ventilation and cooling. Due to the sunlight shining on buildings, machinery and equipment, human body and other heat sources, the temperature in the places requiring ventilation is higher than that outside. The negative pressure fan can quickly exhaust the hot air in the room, keep the room temperature and the outside temperature level, and prevent the temperature rise in the workshop.
2、 Air flow takes away heat from the human body. Air flow accelerates the evaporation of sweat to absorb human heat, thus making the human body feel cool, as cool as the natural wind.
3、 The negative pressure fan only has the function of ventilation and cooling, and has no refrigeration function. It is the feeling of human body to be cool. It is ignorant to say how much temperature the negative pressure fan can drop.
At four o'clock, the whole ventilation project needs to be used together with water curtain, and the temperature in the workshop can be controlled within 28 ℃ in the hottest summer. But people 上一篇：如何將酒店廚房油煙排干凈?
