How to quickly ventilate and cool down the high temperature workshop?

To solve the problem of plant cooling, first find out why the plant is hot, what causes it, and then use the corresponding cooling equipment.

The following characteristics generally exist in the workshop workshop:

1. The area is large and the floor is high, resulting in high cooling costs.

2. Production equipment will produce heat, odor, smoke and dust, and the environment is not good.

3. Open open environment, not closed, not suitable for traditional air conditioning.

4. The air is not circulated, and some steel structure workshops will gather heat, and the indoor heat is uncomfortable.

According to the common characteristics and needs of the workshop, it is recognized that the more scientific cooling scheme is: negative pressure fan and environmental protection air conditioning, which are the combination of these two ventilation and cooling equipment.

1. Shengqinfeng negative pressure fan is to use the characteristics of large air volume to replace the air inside the workshop, and discharge the heat, odor and smoke mixed in the air to the outside.

Negative pressure is formed indoors and positive pressure fresh air outside will enter the room from the air inlet, forming a virtuous cycle and ventilation, thereby improving the situation of high temperature and stuffiness and poor air quality.

Second, the Oriental environmental protection air conditioner is the use of physical evaporation to absorb air heat, cool the outdoor fresh air into the room, neutralize the sensible heat in the workshop, better can be blown on the employees, rich in oxygen content of the comfortable cool breeze to cool down, at the same time, can also improve the vitality of employees.

Unlike traditional air conditioners, there is no compressor, it does not rely on low temperature to cool down, it is more about improving the overall senses, the breeze is gentle, and the energy consumption is low, only one-eighth of the power consumption of the traditional air conditioner, and there is no need for a confined space, and it can also improve work efficiency.

Therefore, the cooling mode of the combined plant workshop of negative pressure fan and environmental protection air conditioner with low energy consumption, wide range of action and diverse functions will be recognized by the market if it meets the characteristics of the problems existing in the previous large-scale factory workshop. The ventilation and cooling of the factory workshop are to find Hubei Sheng Qinfeng.

1.Negative pressure fan, pumping out high temperature and stuffy air to cool down. Install a negative pressure fan on the wall window of the workshop, force the large number of high-temperature stuffy air gathered in the workshop to be discharged to the outside of the workshop, let the negative pressure situation be formed in the workshop, force the air outside the workshop to pour into the workshop for convection ventilation, reduce the content of high-temperature stuffy air in the workshop, and improve the speed of air circulation in the workshop.

2.The cooling water curtain system refrigerates the air outside the workshop and enters the workshop for secondary cooling. The workshop installs the negative pressure fan on the opposite side or the side wall window to install the cooling water curtain system, and the supplementary air entering the workshop is cooled by the cooling water curtain for the second time, and the air that becomes lower temperature is forcibly introduced into the workshop to cool down, this method is used with the negative pressure fan to cool down the best, it should be noted that the amount and speed of the air in the water curtain cooling system should be enough to supplement the amount and speed of the high temperature and stuffy air discharge in the workshop, and the sealing of the workshop should be done. Try to ensure that the air entering the workshop passes through the cooling water curtain system.

3.Environmentally friendly air conditioning, which cools the air outside the workshop and sends it into the workshop for cooling. The outer wall of the workshop is equipped with environmental protection air conditioning, which is to supply air to the workshop through the fan, and the fresh air outside flows through the wet curtain soaked in water, and the air is in full contact with the water while absorbing the sensible heat in the air focus, so as to achieve the purpose of cooling, ventilation, dust removal, and increasing the oxygen content of the air in the workshop, this scheme is especially suitable for high temperature and crowded places.

4.The industrial fan has a large air volume and a wide coverage area, and the single machine can ventilate the workshop area of 800-1600, and the airflow is pushed to the ground in a cone shape from top to bottom, and flows along the horizontal direction to the ground, and pushes up to the roof after encountering the horizontal airflow of the side barrier or near the fan, so as to achieve effective all-round overall ventilation and effective cooling of personnel for the workshop environment.

How to cool down when the temperature of the plant is high? The temperature of large-scale factories is generally very high in summer, and cooling has become a problem, and the normal production of many enterprises has been affected. Although there are also many ways to cool down, it is difficult to find more economical cooling methods, either the cooling effect is not good, or the cost is high and the energy consumption is high.

In fact, the plant can choose environmental protection air conditioning, negative pressure fan and other combination cooling.

Among them, the environmental protection air conditioner is suitable for the cooling of a large area of the plant, which can effectively cool down by 4-10 degrees, quickly ventilate in a short time, extract the hot air, odor and dust in the plant, and inject clean and cool cold air.

In fact, the plant is generally a multi-steel structure, with production workshops, warehouses, etc., and it is not the whole plant that needs to be cooled.

For the installation of environmentally friendly air conditioners, pay attention to:

1. The voltage of the environmental protection air conditioner should be stable, otherwise it will affect the normal operation of the equipment and is not conducive to cooling.

2. Pay attention to the location of the installation of environmental protection air conditioning and the laying of pipes.

3. The air inlet environment of the equipment is fresh, and places with peculiar smells, odors, and thick smoke should be avoided.

4. Regularly and properly clean to avoid clogging and reduce the service life of the equipment.

If there is too much equipment in the high-temperature workshop, you can install environmentally friendly air conditioning, do post air supply, or cool down the workshop as a whole; Environmental protection air conditioning 1 hour 1 degree of electricity can be 100 to 150 square area cooling, cooling can reach 4-10 degrees, low operating costs, compared with the traditional compressor air conditioning, power consumption is only 1 8 of the traditional air conditioner, environmental protection air conditioning not only energy saving and environmental protection but also has ventilation, humidity adjustment, good cooling effect, large coverage area and other characteristics, can be very effective in improving the working and living environment.

Guangdong Hechang 20 years of professional workshop ventilation and cooling project, according to different environmental requirements, to provide diversified solutions.

There are many ways to cool down the workshop, depending on whether you have cooled down as a whole or locally.

Mobile air conditioners can be used for local cooling

1. Small size, generally only the size of a water dispenser, will not take up space at all.

2. It is movable, and the four universal wheels at the bottom ensure that the user can transfer the place of use as he wishes, and is not limited by the use area. No installation is required, plug and play, eliminating the cumbersome installation process of traditional air conditioners, and can be put into use as soon as possible after purchase.

3. The cooling effect is more obvious. The mobile industrial air conditioner blows out the air conditioning air with a temperature difference of 10-15, which can make the user feel comfortable and more useful for cooling and cooling down.

6. Small equipment investment, energy saving and power saving. A mobile industrial air conditioner can meet the cooling needs of 2-3 positions, and the purchase of equipment depends on the number of high-temperature positions, and because it is the use concept of local cooling, it avoids the waste of cooling energy caused by large space and few employees in many factories.

Large industrial air conditioners can be used for overall cooling

1. Strong wind, uniform airflow and low noise, 2. Extend the air duct above the need to cool down, and open holes at intervals, which is the place where the cold air blows evenly to the bottom of the work.

To put it simply, the first need for ventilation to cool down the high-temperature workshop, the purpose of ventilation is to let the original stuffy air in the workshop be discharged outside, and when the stuffy air is discharged outside, it will be sent into the room with environmental protection air conditioning (industrial air cooler). In this way, the cool breeze is recently discharged and the stuffy air is discharged, which realizes a virtuous cycle, and is now a more scientific cooling scheme for the high-temperature workshop.

Among them, negative pressure fans (such as good: Tuhe, Kyushu, Jiafeng) can be used to realize the hot air discharge of the workshop content. And eco-friendly air conditioners (e.g

Penguin Wind, Keruilai, Jiafeng, Aolan, Jiatianxia, etc.) is the use of water evaporation and heat absorption principle to transport cool breeze, similar to blowing sea breeze, to send a steady stream of comfortable cool breeze to the room, which can be cooled in a large area, and can also be partially cooled down by employees.

According to different environments and requirements, different solutions are needed, and post cooling can be used in places where personnel are fixed, and overall cooling must be used in places where personnel are scattered, and cooling equipment includes air conditioners, air coolers, fresh air units, etc.

3000 square meters of steel structure workshop, because the area is relatively large, the overall cooling is not realistic, and the input cost will be very high.

Only some negative pressure fans were used to achieve overall ventilation and ventilation, and then several Jiafeng industrial mobile air coolers were used in the positions where workers were concentrated, and the cool air was conveyed to several places where the personnel were concentrated, which was quite okay.

Plant workshop cooling is now generally selected energy-saving and environmentally friendly equipment, low cost, low energy consumption, good effect, such equipment has negative pressure fan, wet curtain, environmental protection air conditioning, mobile air cooler, their cooling principle is the same, can be decided according to their own plant situation to install what kind of equipment, do not understand can find professionals to view the site after the development of a reasonable ventilation and cooling program.

This is to choose the best plan according to the situation of the collective, there is no absolute best, only to see which is more suitable.

If the workshop is relatively large and there are fewer personnel or there is heating equipment, it is recommended to directly equip employees with water-cooled cooling clothes, which consumes the least electricity, has the most obvious cooling effect, and has the least investment.

There are several ways to cool down the workshop, please refer to:

1. Natural heatstroke prevention and cooling methods.

1. First of all, we should keep the air circulating and open the windows in all corners of the workshop, so that the air can be convection, which will be cooler.

2. Water can be sprinkled on the floor of the workshop, and the water evaporation and heat absorption will absorb part of the heat in the air, and the personnel will be more comfortable.

3. There must be enough drinking water in the workshop, and more water is consumed in summer, and drinking more water can also effectively prevent heatstroke and cool down.

Second, the cooling equipment cooling method.

1. Environmental protection air conditioning, a single unit with an air volume of 18,000 can manage 100-150 square meters of cooling, about 1 kilowatt-hour electricity, and send the air outside the workshop to cool down and send it into the workshop for cooling. The outer wall of the workshop is equipped with environmental protection air conditioning, which is to supply air to the workshop through the fan, and the fresh air outside flows through the wet curtain soaked in water, and the air is in full contact with the moisture while absorbing the sensible heat in the air focus, so as to achieve the purpose of cooling, ventilation, dust removal, and increasing the oxygen content of the air in the workshop, this scheme is especially suitable for high temperature and crowded places.

2. Industrial large fan, diameter meter optional, power, large air volume, wide coverage area, single machine can ventilate to cover the workshop area of 1500, the airflow from top to bottom into a cone to the ground, to the ground along the horizontal direction of flow, encounter the side barrier or near the horizontal airflow of the fan and push up to the roof, to achieve effective all-round overall ventilation and effective cooling of personnel in the workshop environment.

3. Negative pressure fan to pump out high temperature and stuffy air to cool down. Install a negative pressure fan on the wall window of the workshop, force the large number of high-temperature stuffy air gathered in the workshop to be discharged to the outside of the workshop, let the negative pressure situation be formed in the workshop, force the air outside the workshop to pour into the workshop for convection ventilation, reduce the content of high-temperature stuffy air in the workshop, and improve the speed of air circulation in the workshop.

4. The cooling system of the water curtain fan refrigerates the air outside the workshop and enters the workshop for secondary cooling. The workshop installs the negative pressure fan on the opposite side or the side wall window to install the cooling water curtain system, and the supplementary air entering the workshop is cooled by the cooling water curtain for the second time, and the air that becomes lower temperature is forcibly introduced into the workshop to cool down, this method is used with the negative pressure fan to cool down the best, it should be noted that the amount and speed of the air in the water curtain cooling system should be enough to supplement the amount and speed of the high temperature and stuffy air discharge in the workshop, and the sealing of the workshop should be done. Try to ensure that the air entering the workshop passes through the cooling water curtain system.

Look at the budget, the budget is low, and the wet curtain wall is a large industrial fan. However, when the weather is hot, it is estimated that it is a little difficult to block. The budget is a little higher, the wet curtain air cooler, when it is more than 30 degrees outside in summer, the wind blown by the wet curtain air cooler is estimated to be around 30 degrees.

If your budget allows, you can opt for industrial energy-efficient air conditioners. For different venues, targeted plans are made to ensure that the temperature in the venue is controlled within a certain range. It has the effect of **air conditioning, but it saves electricity compared to ordinary ** air conditioning.

1: Install industrial air coolers on the exterior wall or roof.

The environmental protection air conditioner of the industrial air cooler adopts the principle of water evaporation and cooling, but it is different from the water curtain wall in that the fan and the water curtain are in the same equipment, which is a positive pressure air supply, and the doors and windows are required to be opened during operation. Of course, this can also solve the ventilation and cooling problem of tall plants, but due to the large span of tall plants, the installation on the wall cannot meet the requirements of the middle area, and the installation on the roof must also be connected to the air duct.

The shortcomings of its use in tall factories are listed as follows:

1) safety, the environmental protection air conditioner installed on the outer wall generally needs to make a meter-wide triangular bracket to be fixed on the wall, this installation method is difficult to ensure long-term safety due to the large torque, especially the regular personnel climb the bracket for maintenance, inconvenient and have potential safety hazards, it is difficult for general personnel or installers to design a completely reliable bracket according to the stress degree of various walls and the stress degree of the steel structure color steel plate, so that it is difficult to ensure the safety of personnel and equipment, and this hidden danger is aging with the wind, sun and rain bracket, With the aggravation of service life, there have been a number of crashes across the country, which should be taken seriously.

2) The air supply distance of the environmental protection air conditioner installed on the wall with side air supply is limited, generally up to 15 meters, of course, increasing the outlet residual pressure of the fan can increase the air supply distance, but the noise and power consumption increase at the same time, and the strong wind at close range may affect the personnel and process; The air connection pipe greatly increases the cost and affects the aesthetics and the use of workshop machinery. The environmental protection air conditioner installed on the roof must first solve the problem of load-bearing and leakage prevention on the roof, and secondly, it also needs to be connected to the air duct to increase the cost.

3) It is calculated that the power consumption and initial installation cost of the use of external or roof environmental protection air conditioners in tall factories may be twice that of water curtain walls and negative pressure fans. Of course, only for individual positions in the workshop to supply air for cooling, external or roof environmental protection air conditioning is a better choice.

4) There are many domestic environmental protection air conditioning brands, most of which are of average quality, especially cheap machines, with a high failure rate and high maintenance costs. If conditions permit, you can consider: Keruilai, Jiafeng environmental protection air conditioner, Aolan, Jia Tianxia, penguin wind environmental protection air conditioner, these types of big brands, the initial cost is more expensive, and the quality is much more reliable.

2. Ventilation and cooling mode of negative pressure fan.

The negative pressure fan is a good choice for ventilation and cooling of the plant by discharging the stuffy air from the plant to the outside to achieve the circulation of fresh air.
