The environmental protection air conditioner cools the air outside the workshop and then sends it to the workshop for cooling. The utility model is provided with an environmental protection air conditioner on the outer wall of the workshop. The environmental protection air conditioner supplies air to the interior of the workshop through a fan. When the fresh air from the outside passes through a wet curtain soaked in water, The air and water are fully contacted, and the sensible heat at the air focus is absorbed to achieve cooling, ventilation and dust removal, and the oxygen content of the air in the workshop is improved. The scheme is especially suitable for high temperature and crowded places.

The cooling curtain system used for the cooling and ventilation of the factory floor sends the air outside the workshop to the workshop for secondary cooling. A cooling water curtain is set at the window opposite or on one side wall of the negative pressure fan in the workshop. Through the cooling water curtain, the replenishing air flowing into the workshop is carried out secondary cooling. The cooling effect of this method is very good with the negative pressure fan. Attention should be paid to the quantity and flow rate of the air flow in the water curtain cooling system should be enough to supplement the quantity and flow rate of the hot air flow out of the workshop. At the same time, the sealing work of the workshop should be done well, and the air flow into the workshop should be ensured as far as possible through the water curtain cooling system.

The negative pressure fan is used for cooling and ventilating the high temperature and sultry air in the workshop. By setting negative pressure fans in the workshop walls and Windows of the workshop, a large number of high temperature and sultry air gathered inside the workshop is forced to the outside of the workshop, resulting in a negative pressure situation inside the workshop, and the air outside the workshop is forced to flow into the workshop for convection ventilation, which reduces the high temperature and sultry air inside the workshop and increases the air flow speed inside the workshop. This method is suitable for the original poor air flow And the whole workshop has high temperature and hot conditions to be solved.

When the air cooler is in normal operation, it is usually used with drinking water. For a long time, it is easy to appear that the key parts of the wet curtain and the water in the chamber have a lot of dirt in drinking water, water residual and the machine itself damaged residue. In order to ensure the actual effect of ventilation and cooling of the air cooler, the following aspects about the correct maintenance of the industrial water cooler can be referred to by everyone.

1. When the air cooler stops using, clean the frost layer and ice block in the finned tube radiator with clean cold water, discharge the water in the inflow tray, and then change the axial flow fan to dry the water;

2. When cleaning the cold air machine, first pull out the power cord plug, loosen the screw, take out the back cover, and then wipe the filter screen and wet curtain neatly with a wet rag. Pay attention to not wetting other components when wiping, so as to prevent corrosion of components;

3. The fan of the air cooler should be placed horizontally, and the area placed should be far away from fire or flammable materials to prevent the machine from being burned down without cause;

4. When the air cooler is used, check whether there is dust and other obstacles in the inlet vent. If there is any obstacle, wipe it with a dry rag and use it again.

5. The cold air machine should be cleaned frequently to avoid the blockage of the antipollution filter net or volatile hole. If the air cooler is used for a long time but is cleaned regularly, it will also lead to the continuous deposition of the machine basin dirt, leading to common faults of the machine, which will seriously affect the application and reduce its service life

Before we apply the wet curtain air cooler, we need to check whether there is dust and other dirt in the reservoir, which should be cleaned 1-2 times in the service life of the year. The water in the pool should be drinking water or other clean water.

1. The centrifugal fan is the heart of the wet curtain air cooler. If there is a fault, the power should be turned off immediately and the electrician should be asked to repair it immediately. When assembling, attention should be paid to connecting the ground wire. When disassembling the centrifugal impeller, the center should be used to prevent the leaf deformation from colliding with the shell.

2. If the float switch of the wet curtain air cooler fails to operate, and there is less water in the pool or overflow water seepage is found, it should be corrected and replaced in time.

3. If it is found that the power supply of the cooling water curtain is not enough or uneven, it is necessary to check whether there is less water in the pool, whether the water pump is running, and whether the small round hole on the water supply pipe road and the water pump inlet part, especially the spray pipe road, is blocked, and check whether the spray pipe road is located in the middle of the cooling water curtain. Normal sprinkling relative height should be more than 80mm.

4. Because the centrifugal fan of the wet curtain air cooler is of low voltage type (negative pressure and gas pressure are small), there is no way to extend the pipeline in the air vent of the industrial air cooler to exhaust air for long distance.

5. The circuit of the centrifugal fan and water pump of the wet curtain air cooler should be centralized control system, and the control circuit should be installed in the room.

6. In winter, when environmental protection air conditioning and industrial air cooler are not needed, the water in the pool should be added to the net, and the shell should be tied up with plastic film or cloth to prevent sand and dust from entering the room. Odor Solution

The first key factor is that the environmental protection air conditioning is not cleaned on time, and the second is because the water body produces mildew. Because of the long-term use of environmental air conditioning, dust accumulated to the top of the filter, for this matter will emit a smell.

7. When the environmental protection air conditioning application for a period of time, the inside of the filter screen and metal sheet will deposit dust, when the dust is too much will cause odor, seriously affect the quality of the air, affect the exhaust air volume.

8. Because the environmental protection air conditioning is cold, there is often some moisture inside, so after the environmental protection air conditioning is turned off, it is not dry manic mildew reduction function of environmental protection air conditioning is immediately slow down, so that the moisture inside will always be in the inside, for a long time, there will be aspergillus flavus and odor formation.

What are the important characteristics and application fields of large and medium-sized industrial air coolers? Large and medium-sized industrial air cooler can not only maintain indoor air quality clean, clean, environmental health, large and medium-sized industrial air cooler can also avoid dry air and so on. Large and medium-sized industrial air coolers are widely used in textiles, machinery and equipment, porcelain, hospital outpatient clinic, school and other industries. The following large and medium-sized industrial air cooler Xiaobian to give you a detailed explanation of the relevant information! The characteristics of large and medium-sized industrial air coolers are mainly divided into the following aspects:

1, large and medium-sized industrial air cooler completely energy-saving large and medium-sized industrial air cooler commodities: large and medium-sized industrial air cooler is no compressor, no cold coal, zero pollution energy-saving large and medium-sized industrial air cooler commodities, large and medium-sized industrial air cooler is the use of outdoor air cooling basic principle and carry out heat convection ventilation in the room to achieve natural ventilation cooling effect.
