1. Workshop air cooler cooling project scheme

        ①. Solution: install air cooler for ventilation and cooling.

        ②. Cooling working principle: Using negative pressure ventilation, the physical principle of air convection design, using the knowledge of fluid mechanics, scientific rigorous calculation design blade Angle, the motor power, speed, air pressure, air volume, in the fan electricity work, quickly achieve a lot of smoke volume, make indoor environment quickly and produce an outdoor air pressure difference, form a powerful negative pressure, Forced the indoor pollution hot air must be in the direction of the flow we set emitted quickly, in indoor air pressure drop, air getting thinner, form a negative pressure zone emitted at the same time, force the outdoor fresh air along the air pressure difference compensation into indoor, so as to achieve the workshop factory exhaust smoke and exhaust heat, dust, ventilation and air circulation cooling effect.

2. Specific implementation

        In the practical application of the workshop, the air cooler is usually installed on one side of the injection workshop, and the air inlet is located on the other side of the workshop. The air is formed by the air inlet to the negative pressure fan. In this process, close to the negative pressure fan near the doors and Windows should be kept closed, forced air by the inlet side of the door and window compensation into the workshop, from the workshop, the negative pressure fan discharged from the workshop, complete ventilation, efficient, ventilation rate can be as high as 99%. Through scientific and reasonable design, any high heat, harmful gas, dust and smoke can be quickly discharged from the workshop, poor ventilation and other problems can be completely solved once.

3. Ventilation and cooling effect

        The effect of air cooler ventilation and cooling is better. It is mainly aimed at solving the causes of high temperature and sultry caused by heat accumulation in the workshop. The negative pressure ventilation is used to pump the hot air out of the workshop quickly, and the cool air is introduced into the outdoor convection exchange, so as to reduce the indoor temperature of the injection molding workshop. As we know, the temperature in places requiring ventilation keeps rising due to the sunlight shining on buildings, machinery and equipment, human body and other heat sources, and it is concentrated indoors and cannot be excluded from outdoors. Negative pressure fan is the use of mechanical kinetic energy, working can quickly exhaust the hot air inside the injection workshop, so that the room temperature and the outside temperature is flat, not workshop temperature rise.
