How to cool the factory building?
There are two main ways to cool down the workshop: installing roof ventilation balls to cool down and installing environmental protection air conditioners.
1. Install the roof vent ball for ventilation and cooling.
Roof ventilation ball is a kind of ventilation equipment which relies on the principle of air convection and does not need electricity, and relies on the natural wind on the roof of the factory building to blow the fan blades to produce a certain amount of ventilation. When the indoor and outdoor air environments are different, air will flow, thus eliminating indoor waste gas and hot air. Its advantage is that it does not need extra electricity and is more environmentally friendly. However, it is highly dependent on the environment and cannot be forced to exhaust.
2. Install environmental protection air conditioner
Ventilating doors and windows and installing negative pressure fans can only enhance the flow and discharge of hot and stuffy air in steel structure workshops. If the air temperature in the steel structure factory building is to be lower and the cooling effect is more obvious, environmental protection air conditioners can be installed to send cold air into the factory building with positive pressure, and the air and cold air in the factory building are forced to neutralize and cool down, so as to improve the speed of air overflowing from the factory building and carry out forced airflow ventilation.
How to do simple heat insulation in the factory building?
1, increasing the thermal resistance and thermal stability of the envelope.
Setting solid material insulation layer on the roof is to use the thermal resistance of the roof material layer and the function of material heat storage to insulate the heat, aiming at improving the thermal inertia of the structure, thus reducing the average temperature and temperature fluctuation range of the roof surface. For residential rooms that are used all day, the roof should have enough thermal resistance and attenuation, and it should be delayed for a longer time.
2, set the roof overhead ventilation insulation layer.
The principle of ventilated roof is to set ventilation interlayer on the roof. On the one hand, the outer layer of ventilation interlayer is used to block the sun, which makes the roof become secondary heat transfer and prevents the solar radiation heat from directly acting on the envelope structure. On the other hand, the effect of wind pressure and hot pressing, especially natural ventilation, is used to take away the heat entering the interlayer, thus reducing the influence of outdoor thermal action on the inner surface.
3. Adopt attic roof, water storage roof and vegetation roof.
Attic roof is one of the common roof forms in buildings. Air holes are often opened at cornices, roofs or gables, which is helpful for ventilation, dehumidification and heat dissipation. The water storage roof is an aquifer made on the flat roof of fine stone concrete.
Vegetation roof is to plant all kinds of green plants with soil or other media on the waterproof layer of the roof. Using evaporation and photosynthesis of plants to shade the sun and absorb solar radiation heat can reduce the influence of solar radiation heat on the roof.
The above content is all the information that Bian Xiao analyzed about how to cool the factory building and how to do simple heat preservation. I hope I can bring you some help. At present, there are two main cooling methods in the mainstream workshop, and the above three insulation methods can be tried, each of which is suitable for different situations.
