We see that all the injection workshops are high temperature, sweltering, and the temperature even reaches 40-45 degrees, or even higher. Some injection molding workshops have a lot of high -power axis flowers. After environmental protection air conditioners, the problem of high temperature and hotness cannot be improved, and it does not feel the effect of cooling. Some factories installed several large central air conditioners for the injection molding workshop, but it was still high -temperature and sullen, without significant improvements.

Let’s make an evaluation first. What is the total power of a 1000 -square -meter injection molding workshop? It may be 800 kilowatts, it may be 1300 kilowatts, or it may be 2000 kilowatts. The heat generated by the energy consumption of the injection molding machine is only a part of the heat discharged through the cooling water of the mold, and the large amount of heat emitted in the air cannot be discharged in time. How can the central air -conditioning refrigeration that matches the high -power central air conditioning to neutralize the heat? I think this is already a question that has no practical significance. Will refrigeration will be a astronomical number required for the heat and neutrality. Maybe it matches such a high -power central air conditioner?

Since the central air conditioner does not reach the cooling effect, is it okay to evaporate and refrigerate with water? Most people think of discharging heat through the fan and replacing fresh air. A bearing fan with a diameter of 800mm is 5.5 kilowatts or 4.5 kilowatts, and the power consumption is very large. Why do those injection molding workshops in a large large bearing fans still do not feel the effect of improvement like the original?

There are three reasons for the poor cooling effect of the injection molding workshop:

1. The efficiency of the fueling of the axis fans is too low. The speed of the axis fans is generally 2800 or 1400 rpm. High energy consumption, big noise, and inefficient.

2. The wind turbine installation position is wrong, and the fan is installed around the workshop.

3. There is no closed window, the discharged gas comes in from the window, the air turns between the fan and the window, and the gas in the workshop cannot be drawn.

The only correct ventilation and cooling solution of the injection molding workshop is negative pressure ventilation. Wind speed and air conversion times can be designed. It can be exhaled once in 1 minute or it can be made into 30 seconds. The wind speed also depends on the distance from the air inlet to the outlet. If the distance from the air inlet to the outlet is 60 meters, the number of air changes is once a minute, then the wind speed = 60 meters/60 seconds = 1 meter/second. A 56 -inch negative pressure fan can ensure that the 800 cubic meter space plant is breathable once in one minute. In such a rapid ventilation, the temperature of the workshop cannot rise. Natural hair drying makes the human body feel cool and comfortable. The negative pressure fans are discharged out of the air to reduce the indoor air pressure, the indoor air becomes thin, forming a negative pressure area, and the air flows into the room due to the pressure difference between the air pressure. In the actual application of the industrial plant, the negative pressure fan is concentrated on the side of the plant, the air inlet is on the other side of the plant building, and the air from the air inlet to the negative pressure fir forms a convection blower. In the process, the doors and windows near the negative fans are closed, and the air is forced to flow into the workshop from the doors and windows of the air inlet. The air was discharged from the air inlet to the workshop from the airport, flowing from the workshop, and the workshop was discharged from the negative pressure fan. The ventilation is thorough and efficient, and the air pressure can be as high as 99%.

If you want to achieve the effect of air conditioning, you can install water curtains in the air in the air. Why can’t the effect of environmental air conditioners be done? In the face of a special environment, who is a master naturally distinguished.
