Addressing Summer Cooling Challenges for Industrial Water Chillers

During summer chiller usage, ultrahigh water temperature or cooling failure after long-time operation might stem from incorrect chiller selection, external factors, or internal malfunctions of the industrial water chiller.

1. Proper Chiller Matching

When selecting a water chiller, ensure it aligns with your laser equipment’s power and cooling requirements. This guarantees effective cooling, normal equipment operation, and a prolonged lifespan. With 21 years of experience, TEYU S&A team can expertly guide your chiller selection.

2. External Factors

When the temperature exceeds 40°C, industrial chillers struggle to effectively convert heat, leading to poor heat dissipation within the refrigeration system. It is recommended to position the chiller in an environment with a room temperature below 40°C and good ventilation. Optimal operation occurs between 20°C and 30°C.

Summer marks a peak in electricity consumption, causing fluctuations in grid voltage based on actual power usage; excessively low or high voltages can disrupt equipment's regular operation. It is recommended to utilize a stable voltage, such as a single-phase supply at 220V or three-phase supply at 380V.

3. Inspecting the Internal System of the Industrial Chiller

(1)Verify if the chiller's water level is adequate; Add water up to the highest level of the green zone on the water level indicator. During the chiller installation, ensure that there's no air inside the unit, water pump, or pipelines. Even a small amount of air can disrupt the chiller's operation.

(2)Insufficient refrigerant in the chiller can impair its cooling performance. If a refrigerant shortage occurs, contact our customer service technicians to locate leaks, perform necessary repairs, and recharge the refrigerant.

(3)Monitor the compressor. Prolonged compressor operation might lead to issues like aging, increased clearances, or compromised seals. This results in reduced actual exhaust capacity and a decline in the overall cooling performance. Additionally, anomalies like decreased capacitance or internal irregularities of the compressor can also cause cooling abnormalities, necessitating maintenance or replacement of the compressor.

4. Strengthening Maintenance for Optimal Cooling Efficiency

Regularly clean dust filters and condenser grime, and replace circulating water to prevent inadequate heat dissipation or pipeline blockages that could reduce cooling efficiency.

To maintain chiller functionality, it’s also important to monitor the ambient temperature and humidity changes, inspect electrical circuits regularly, provide proper space for heat dissipation, and conduct comprehensive safety inspections before restarting long-inactive equipment.

Operation Guide for TEYU S&A Laser Chiller Refrigerant Charging

If you find that the cooling effect of the laser chiller is unsatisfactory, it may be due to insufficient refrigerant. Today, we will use the rack-mounted fiber laser chiller RMFL-2000 as an example to teach you how to properly charge the refrigerant.

 

Steps for Chiller Refrigerant Charging:

 First, please operate in a spacious and well-ventilated area while wearing safety gloves. Also, no smoking, please!

 Next, let's get to the point: Use a Phillips screwdriver to remove the upper sheet metal screws, locate the refrigerant charging port, and gently pull it outwards. Then, unscrew the sealing cap of the charging port and easily loosen the valve core until the refrigerant is released.

 ATTENTION: The internal pressure of the copper pipe is relatively high, so do not fully loosen the valve core all at once. After the refrigerant inside the water chiller is completely released, use a vacuum pump to extract the air inside the chiller for about 60 minutes. Before vacuuming, please remember to tighten the valve core.

 Finally, it is recommended that you slightly open the valve of the refrigerant bottle to purge any air trapped inside the pipe and to avoid excessive air entering when you connect it to the charging pipe.

 

Chiller Refrigerant Charging Tips:

1. Choose the appropriate type and weight of refrigerant based on the compressor and model.

2. It is permissible to charge an additional 10-30g beyond the rated weight, but overcharging may cause compressor overload or shutdown.

3. After injecting an adequate amount of refrigerant, promptly close the refrigerant bottle, disconnect the charging hose, and tighten the sealing cap.

 

TEYU S&A Chiller uses the environmentally friendly refrigerant R-410a. R-410a is a chlorine-free, fluorinated alkane refrigerant that is a non-azeotropic mixture under normal temperature and pressure. The gas is colorless, and when stored in a steel cylinder, it is compressed liquefied gas. It has an Ozone Depletion Potential (ODP) of 0, making R-410a an environmentally friendly refrigerant that does not harm the ozone layer.

 

These guidelines provide detailed steps and precautions for charging refrigerant in the RMFL-2000 fiber laser chiller. We hope this information is helpful to you. For further insights on refrigerants, you can refer to the article Industrial Water Chiller Refrigerant's Classification And Introduction.

How to Choose a Suitable Laser Chiller for Your Fiber Laser Cleaning Machine?

When choosing a laser chiller for your 6000W fiber laser cleaning machine, you need to consider some factors, such as the cooling capacity of the laser chiller, the temperature stability, the cooling method, the chiller brand, etc. Here are some tips for you:

First, you need to determine the cooling capacity required for your laser. This is typically measured in kilowatts (kW) and should match or exceed the power output of your laser. TEYU CWFL-6000 laser chiller is specially designed by TEYU S&A chiller manufacturer for 6000 fiber laser, perfect for cooling 6000W laser cleaning machines, 6000W laser welding machines, 6000W laser cutting machines, 6000W laser engraving machines, etc.

Next, you should consider the temperature stability required for your laser system. Some lasers are more sensitive to temperature fluctuations than others, so it's important to choose a chiller that can maintain a stable temperature within the desired range. TEYU CWFL-6000 laser chiller has a water temperature control range of 5°C ~35°C and a precision of ±1℃, perfectly meeting the temperature control range and precision requirements of 6000W fiber lasers on the market.

You may also want to consider the cooling method used by the laser chiller, which depends on your specific needs and available resources.

Refrigeration Principle Of TEYU Chiller For Supporting Equipment: The laser chiller's refrigeration system cools the water, and the water pump delivers the low-temperature cooling water to the laser equipment that needs to be cooled. As the cooling water takes away the heat, it heats up and returns to the chiller, where it is cooled again and transported back to the fiber laser equipment.

Refrigeration Principle Of The TEYU Laser Chiller Itself: In the refrigeration system of a chiller, the refrigerant in the evaporator coil absorbs the heat of the return water and vaporizes into steam. The compressor continuously extracts the generated steam from the evaporator and compresses it. The compressed high-temperature, high-pressure steam is sent to the condenser and later releases heat (heat extracted by the fan) and condenses into a high-pressure liquid. After being reduced by the throttling device, it enters the evaporator to be vaporized, absorbs the heat of the water, and the whole process circulates constantly. You can set or observe the working status of the water temperature through the temperature controller.

Additionally, it's important to consider the size and weight of the chiller, as well as any space limitations you may have in your facility. You'll want to ensure that the chiller can be easily installed and integrated into your laser system. All of TEYU's chillers are specially designed by TEYU's R&D team, combining the smallest volume and maximum cooling capacity to produce the best cost-effective products.

Lastly, it's always a good idea to consult with the chiller manufacturer or an expert in laser cooling systems to ensure you choose the most suitable chiller for your specific application. They can provide you with more specific recommendations based on the details of your laser cleaning machine. TEYU S&A Chiller has 21 years of experience in laser cooling. In 2022, the sales volume of chiller products has exceeded 120,000 units, selling well in more than 100 countries and regions around the world.
