Air - cooled air cooler suddenly does not cool how to do?

Air cooler is a kind of refrigeration equipment, which can give temperature control, constant current power supply and voltage regulator. The principle of the air cooler is to introduce a certain amount of water into the internal structure of the machine storage tank, according to the cold water mechanism will automatically cool the circulating water, and then the structure of the machine and equipment centrifugal pump will introduce the low temperature frozen water into the refrigeration equipment, the frozen water will bring the internal structure of the machine and equipment heat, the hot water in high temperature weather once again flow back to the storage tank for cooling. Such reciprocating exchange refrigeration, to complete the role of mechanical equipment refrigeration. According to the different refrigeration methods of chiller, it can be divided into air - cooled chiller and ice - water unit.
In actual use, in our air cooled air cooler suddenly does not refrigerate, what is the reason?
When the air-cooled air cooler is in operation, the liquid refrigerant in the evaporator continues to absorb heat from the water and immediately evaporates. According to the reduction of the refrigeration compressor and the relief valve of the air conditioning condenser, it also becomes low temperature and low pressure refrigerant into the evaporator for recirculation.
1) If the air cooled air cooler is used for too long, the refrigerant will volatilize, thus harming the actual effect of refrigeration. Another reason is that the refrigerant leaks, which is not enough to harm the refrigeration, so you should observe whether the refrigerant is enough. In the case of exposed refrigerant, find the leakage waterproof leak, therefore, be sure to maintain and eliminate the filtration system of his laser generator refrigeration unit, when the blockage is serious, it is recommended to replace the gas-liquid separator.
2) There is also too much water sediment in the air cooled air cooler, which adheres to the inner wall of the tap water pipeline, causing a shortage of water supply, thus affecting the actual effect of refrigeration. Therefore, in areas with poor water quality, sewage treatment technology should be done or water pipes should be removed and replaced in time to ensure the normal operation of refrigeration units.
3) The condenser is not cleaned for a long time. The condenser is one of the main components of the refrigeration unit. For a long time, it is easy to be corroded, resulting in the reduction of the heat conduction effect of the condenser. In the case of very serious scaling, the pipeline will be blocked, so that the actual effect of the heat conduction of the air-cooled air cooler will be missing, thus affecting the actual effect of refrigeration. Therefore, it is recommended to clean the condenser about once in half a year.
In general, his air cooler must be eliminated and maintained regularly in the process of use, so that the characteristics of the machine and equipment can be more stable, the service life can be more long-term, and the work efficiency can be higher.

Installation of negative pressure fan, should be designed how much ventilation high efficiency

In the specific use of the plant, the negative pressure air will be centralized on one side of the industrial plant, and the air intake will be on the other side of the plant. The gas flows from the air intake into the machine and equipment, producing heat convection blowing.
Negative pressure fan
In this process, the negative pressure fan and the aluminum doors and Windows adjacent to the fan remain closed, driving the gas into the workshop through the aluminum doors and Windows on the intake side. The gas is injected into the workshop from the air inlet in an orderly manner, flows through the workshop, and is discharged from the workshop by the negative pressure fan centrifugal fan. The ventilation rate is as high as 99%. Through detailed project planning and ventilation speed and wind according to the actual demand, all the high fever, harmful substances, dust and smoke can be quickly discharged from the workshop, and all the problems of poor ventilation can be solved. The actual effect of ventilation can be reached within a few seconds after the fan is turned on.

How do you go about choosing the total number of installations you need?
1. First of all, you should consider that there is not a lot of pyrogen in the memory of the workshop where they must install the negative pressure fan;
2. Whether there is large smoke and dust in the workshop;
3. Whether the workshop has a good natural air supply environment;

The above three points determine the number and model selection of your negative pressure fans;
Most workshops are due to poor ventilation capacity, according to the aluminum doors and Windows themselves can not achieve efficient ventilation effect; Especially in the summer, stuffy weather, the room experience is best noticeable. The key to the installation of negative pressure fan is to exhaust more polluting dust particles out of the room through the negative pressure ratio of the fan, so as to effectively improve the office environment and make the indoor air quality cleaner and more transparent. Generally, when installing negative pressure fans, the priority issues of caloric value and pollutants are mainly taken into account. It is proposed that the key caloric value and environmental pollution of the workshop be discharged out of the room at the first time, so as to improve the actual effect of ventilation. This application can effectively deal with many problems existing in your current factory, such as very serious smoke and fine dust in the air.
The actual installation site will be determined according to the site installation standard; When you are dealing with heat, smoke and dust at the same time, it is generally recommended that the ventilation efficiency is not less than the normal ventilation every three minutes; According to this high efficiency to select the total number, generally in a certain range of total, but there are also relatively high requirements, a minute ventilation.

How to extend the service life of Ningbo air cooler

1. Clean the air cooler water tank. Open the discharge valve, wash with tap water can be; If the dust or dirt deposition is more, it should be taken off first, and then washed with tap water.
2. Clean the volatile screen, namely the wet curtain. Remove the wet curtain, wash with tap water can be, if there is difficult to wash the material above the wet curtain, can first use tap water to infiltrate it, straight to the wet curtain spray central air conditioning cleaning liquid, to be thoroughly infiltrated into the wet curtain for 5 minutes, then change the tap water wash, until the residue in the wet curtain can get rid of.
3. Wet curtain air cooler long-term without daily maintenance. The water resource gate valve of the main closed air cooler should be removed. The wet curtain should be removed and the water in the clear water tank should be drained together to completely clean the water tank of the air cooler. After cleaning, install the wet curtain, open the air cooler, exhaust air for 5min~8min, after the wet curtain is dried, the main switch power supply of the closed air cooler can be used.
4. Odor removal. After the application of wet curtain air cooler for a period of time, if the air cooler is not cleaned and maintained, it may lead to heavy cold air smell from the air cooler. At this time, it is necessary to clean the wet curtain and water tank of the air cooler in the whole process according to the second point above. If the odor is still heavy, you can add some chlorine-containing disinfectant to the air cooler water tank from the starting situation, so that the disinfectant is enough to penetrate into the wet curtain and every corner of the air cooler, so that the circulation of disinfection and sterilization several times, you can move the air cooler odor.
Precautions for use
1. When cleaning the wet curtain cold air machine, the main power supply of the air cooler should be completely cut off, and the sign of "Maintenance, prohibited application" should be hung at the control circuit to prevent some people from starting by mistake, leading to risks.
2. When cleaning the wet curtain, the cold air should be carefully removed, and the pressure should not be too large to prevent damage to the wet curtain. Do not put all corrosive chemicals to prevent erosion of the wet curtain.
3. It is necessary to fasten the safety belt when working at high places to ensure safety
