How to deal with poor heat dissipation of screw chiller - Oumalchiller.com

 Industrial chillers can realize mutual switching, speed up production progress, reduce energy consumption, improve product molding efficiency, suppress product defects, and reduce the occurrence of defective products. Screw chillers are widely used in many fields such as electronics, rubber, plastics, papermaking, petroleum, chemical industry, food, machinery, brewing, vacuum coating, pharmaceuticals, etc., and are also widely used in places with centralized cooling to facilitate centralized management.


In industrial manufacturing, chillers are crucial to the transfer of heat. However, many chiller ma chines are prone to poor heat dissipation after a period of actual operation. At this time, product maintenance should be carried out in a timely manner.


First of all, let's clarify the signs of poor heat dissipation of the chiller. When the condenser of the chiller has poor heat dissipation, the efficiency of the compressor will decrease, and the operating current will increase, which will eventually lead to the air-cooled chiller high pressure. When the air-cooled high pressure rises to 24kg/cm2, the water-cooled chiller high pressure will rise to 20kg/cm2 is a sign of poor heat dissipation of the chiller. At this time, maintenance should be carried out in time.


Poor heat dissipation and treatment methods of water-cooled screw chiller:

When the heat dissipation of the condenser is poor, the efficiency of the compressor will be low, and the operating current will increase. The compressor will trip due to the protection of the high-voltage switch, causing the compressor to stop running. Whether the circulating water of the cooling tower is normal, whether the temperature of the cooling water is too high, whether the cooling tower fan pump is running, and whether the cooling water valve is open. After the above things are normal, you need to press the reset button again, or shut down and restart to operate normally. If high pressure overload occurs frequently, the condenser needs to be cleaned.



Treatment method for poor heat dissipation of air-cooled screw chiller:

1. Check whether thefin condenser of the chiller isdirty, if so, clean it with a small brush.

2. Check whether the fan of the chiller is working normally. If not, you can blow it with air or wipe it clean with a soft cloth dipped in some detergent.

3. Move the chiller to a well-ventilated place to avoid blocking the radiator.

4. If the heat dissipation performance of the chiller is still not good, you can consider upgrading the accessories of the chiller, such as fans, heat sinks or other components.



The above is Oumal's solution to the poor heat dissipation of the chiller. For more detailed information, please contact our Oumal manufacturer or Oumal sales: oumal@oumal.com.

Avoid Downtime, Cut Costs: Smart Maintenance for Smarter Chillers

  Screw water-cooled chillers   typically operate around 3,000 hours per year, depending on China's climate and geographical conditions. Regular and scientific maintenance is crucial to ensure long-term, reliable operation, extend the lifespan, and reduce operating costs. Maintenance and Upkeep Preventive maintenance during operation and inspection involves creating annual and monthly maintenance plans based on actual operating conditions. Shutdown Procedures In winter, clean and dry the unit. Open the drain valve to empty the  shell-and-tube heat exchanger  to avoid freezing. The shutdown sequence is: chiller off - cooling tower fan off - cooling water pump off - chilled water pump off. Special attention to anti-freezing: 1. Drain the evaporator and condenser if the unit is outdoors below 0°C during standby. 2. Interlock the water flow switch with the unit to prevent freezing when the chilled water flow switch malfunctions. 3. Ensure water in the evaporator is flowi...

What are the differences between air-cooled chillers and water-cooled chillers | Oumalchiller.com

  We all know that according to different heat dissipation methods, chillers can be divided into air-cooled chillers and water-cooled chillers. What is the difference between air-cooled chillers and water-cooled chillers? ​ 1. The  air-cooled chiller  uses copper tubes and aluminum fins to dissipate heat from the condenser. A fan is required to blow the outdoor air through the heat exchange fins and take away the heat of the condenser, so the air-cooled chiller does not need to be connected to the cooling tower. But compared with water-cooled chillers, under the same power, air-cooled chillers have larger equipment size and higher noise. The condenser of water-cooled chillers exchanges heat with the cooling water from the cooling tower through the heat exchanger. The excess waste heat will be transported to the cooling tower through the cooling water loop and released into the atmosphere, or enter the water-water heat exchanger or soil heat exchange coil for storage. Ther...

What is difference between centrifugal chiller and screw chillers?

 Water Chillers are generally divided into the following categories: screw chillers, centrifugal chillers, water ring heat pump units, plate and tube evaporative condensing screw chillers, thermal storage air conditioners, etc. Screw chiller and centrifugal chiller are equipment that we often encounter. Below,  Oumal Refrigeration  will take you to understand the difference between centrifugal chiller and screw chiller? What is a  screw chiller ? The compressor adopts a screw type, hence the name screw chiller. The refrigerant coming out of the evaporator of the unit is a gas; after adiabatic compression by the compressor, it becomes a high-temperature and high-pressure state. The compressed gas refrigerant is isobarically cooled and condensed in the condenser. After condensation, it changes into liquid refrigerant, and then expands to low pressure through the throttle valve and becomes a gas-liquid mixture. The liquid refrigerant under low temperature and low pressu...
