With the global awareness of energy saving and environmental protection has been strengthened as an industrial energy saving imperative subject --- industrial plants. The steel plant in the energy and steel plant insulation system is directly related to the merits of steel plant insulation system is a key plant indicators of environmental measure.
Workers say that a lot of companies, one to the dog days of summer, steel plant in Dongguan is like a furnace, the room temperature is higher than the outdoor temperature. Steel plant cooling is a comprehensive problem, solve it requires the right remedy, we must first find the key factors affecting the temperature steel plant, focusing on its governance, then select the appropriate method for the targeted treatment of other relatively minor factors in order to achieve good indoor environment and its highest price.
To cool the steel plant in Dongguan, we should consider the following questions:
1, insulation properties Steel plant How?
2, how ventilation performance steel plant?
3. Is there a steel plant cooling system?
First, the steel plant cooling insulation
Steel plant thermal energy interval most of the solar radiation and heat conduction, reducing the formation of indoor greenhouse. Thus greatly reducing the temperature of the plant, to improve the steel plant environment. Now commonly used method has the following two options:
. ① to roof stamped steel plant cotton insulation, cotton insulation is generally used on the roof is glass wool, commonly a thickness of 50mm, 75mm, 100mm, density of 10kg / m3; there is also a polystyrene foam board insulation. Usually installed can reduce the indoor temperature 5-8 ℃, the construction process is more complex, if the transformation of the old plant to make insulation, need to remove the existing roof, up the steel wire, the wire-line laying glass wool, covered with original roof, do water treatment.
②. Spray on efficient roof insulation reflective coatings. Such products with excellent insulation properties, excellent albedo can be reflected off of 75% of the sunlight, up to 95% of the emission rate of the substrate can be quickly dissipated heat accumulation, has low thermal conductivity coefficient (0.058 w / mk). If you use this method, the construction is convenient, no damage to the original roof, and the roof can prevent aging and corrosion. After the construction and pre-construction plate surface temperature difference of up to 20 ℃, the indoor temperature up to 8-10 ℃, 30-70% overall energy consumption can be dropped.
Second, the steel plant ventilation and cooling
Because some machines in the steel plant to produce heat and steam, the heat and water vapor, if not discharged, it will accumulate in the plant, so that the effects of elevated temperature steel plant steel plant environment. To solve these problems is to ensure proper ventilation plant, installation of an appropriate amount of a suitable ventilation system. Reasonable ventilation system installed will significantly improve the steel plant air environment, a large steel plant reduced temperature
Install roof ventilation without power, no power ventilation relies on air convection principles ventilating a ventilation device, when there are differences of indoor and outdoor air environment, will produce air flow, thus eliminating emissions and indoor heat. The advantage is that no additional power, more environmentally friendly. However, a strong dependence on the environment, can not be forced ventilation. The major products are turbine ventilators, ventilation strip (lighting with ventilation), roof ventilators and so on.
Install roof forced air ventilation fan is a machine powered by electricity-driven ventilation equipment. Its effect is good ventilation, ventilation can adapt to any environment.
Third, the steel plant forced cooling
Forced cooling means powerhouse roof installation chiller, water cooled chiller is the use of the principle of cooling air from strong exhaust fan to cool air supplied to the interior of the machine. It allows steel plant indoor temperature is kept at a comfortable temperature of 26-30 ℃. Its power consumption, increase their energy consumption and improve the overall cost.
