Difficulties of many steel processing plant cooling in summer. The total area of the industrial plant is large, and the aspect ratio is high. When the outdoor temperature is 35 ° C, the temperature in the industrial plant will be around 40 ° C, and the top will exceed 50 ° C or even higher 2. The operation cost of traditional central air-conditioning cooling is too high, the cost of electricity costs for events is higher, it is difficult to solve the essential problems of roof insulation, and the actual effect of improvement is not good.

The steel structure workshop is a steel frame structure. Although the building is tall, it is also insulated. However, it is still hot in the summer production workshop, and the employees are very uncomfortable with sweating during the work inside. Department on the spot.

Cooling solution for steel structure workshop, highly recommended:

1. Negative pressure fan, exhausting hot and hot gas to cool down. Install negative pressure fans on the wall windows of the production workshop of the industrial plant

Many accumulated hot and hot gases are discharged outside the production workshop, causing air pressure trends in the production workshop, driving the gas outside the production workshop into the production workshop.

Heat to circulation gas, reduce the moisture content of hot and hot gas in the production workshop, and improve the indoor ventilation rate in the production workshop. This method is suitable for the original empty space.

The circulation of gas commodities is blocked, and the general production workshop often has production workshops that must be handled under high temperature and hot conditions.

2. Cooling water curtain system to cool the gas outside the production workshop and enter the workshop to cool down. Opposite door or side wall of negative pressure fan installed in production workshop

A cooling water curtain system is installed on the window of the wall, and the filling gas entering the production workshop is cooled again by the cooling water curtain, and the temperature becomes even higher.

Low gas is forced into the production workshop to be cooled by the negative pressure fan. This method cooperates with the negative pressure fan to reduce the temperature.

Note that the amount and rate of the software of the water curtain cooling system software should be sufficient to fill the amount and rate of the hot and hot gases discharged from the production workshop, and

To ensure the tightness of the production workshop, as far as possible, ensure that the gas entering the production workshop goes through the cooling water curtain system.

3.Environment-friendly air-conditioning, cooling the gas outside the production workshop and sending it to the production workshop to cool down. Environmentally friendly air conditioners are installed on the outside walls of the production workshop, which are based on centrifugal fans

Exhaust air into the production workshop. The outdoor air is fresh and flowing through the soaked cooling water curtain. After the gas and moisture touch it, it digests and absorbs the most important gas.

Sensible heat, which in turn exceeds the goals of cooling, aeration, ash removal, and increasing the oxygen content of the gas in the production workshop. This plan is very suitable for high temperatures

And crowd gathering venues. Strong actual cooling effect: In the hot area, the equipment can usually cool down more than the actual effect of 4-10 ℃, and the cooling speed is fast, the exhaust air volume is large, the exhaust air is far: the larger exhaust air volume per hour is 18000-60000m³, according to customers According to regulations, people's equipment has high air pressure and exhaust air. Stable characteristics and reliable quality: "5090 volatility net" after 100mm is selected to have a strong cooling performance, and three-leaf forward-swept axial-flow fan blades are used, with low noise and high efficiency. Environmental protection and energy saving: Each unit with a total area of 100-150 square meters requires only 1 kWh per hour. Power saving: Energy consumption is only 1/8 of traditional central air-conditioning, and project investment is only 1/5 of domestic central air-conditioning. Not limited by the natural environment, open fire semi-open production workshop can be applied.

Cooling solution of steel structure workshop:

1. The overall cooling of the plant is suitable for:

 A. Workers' positions are not fixed

 B. Focus on the overall cooling of the environment

 C. Use the positive pressure of the space to prevent dust from entering

 D. Heat sources can be controlled or restricted

 E. Plant area is relatively small

The overall cooling will bring the maximum comfort to the entire plant, and is especially suitable for workshops where the workers' workstations are not fixed and the equipment or goods that need to be cooled are highly mobile. If concentrated cooling is required in some specific areas, fixed-point cooling can be increased to form an "overall-fixed-point" cooling mode.

2. Regional cooling applies to:

 A. Large plant area

 B. Workers and equipment to be cooled are relatively fixed in a certain area

 C. Work area layout is obvious

 D. There is no need to cool down outside the work area, so that it has a cooling effect and saves the customer's investment costs, killing two birds with one stone.

3. The fixed-point cooling of work positions is suitable for:

 A. Worker positions are relatively solid.

 B. Large workshop area

 C. Heat sources spread throughout the space

 D. Least Cost Design
