With the rise in temperature in hot weather, most industrial chillers are experiencing high-pressure alarms, which are extremely inconvenient. High-pressure alarms are a built-in safety feature of chillers that avoid damage in non-cooling operation of the system. The article deals with the reason for high-pressure alarms in chillers and the solution to the issue.
Why Do High-Pressure Alarms Occur?
High-pressure alarms are usually the result of poor heat dissipation in the chiller system. If the condenser cannot dissipate heat, the system pressure rises, triggering the alarm. High condenser outlet water temperature or high air temperature are among the most prevalent causes, both of which prevent the condenser from dissipating heat.
How to Troubleshoot High-Pressure Alarms in Chillers
1. For Air-Cooled Chillers
The most common cause of ineffective heat dissipation in air-cooled chillers is the dust on the surface of the condenser. Dust will eventually block the airflow, so the condenser will no longer cool. To repair this issue:
Clean the Condenser: Clean off the dust from the condenser surface from time to time to enable free airflow and heat dissipation.
Enhance Ventilation: Enhance ventilation in the machine room to lower the ambient temperature, which in turn will increase the efficiency of the condenser.
2. For Water-Cooled Chillers
For water-cooled chillers, internal copper pipe scaling of the condenser is a common problem. Once water scale has developed, it prevents the heat exchange process, causing the chiller to operate inefficiently. The solution is as follows:
Clean the Condenser: Clean the condenser every so often to clear scale deposits and maintain it efficient at heat exchange.
Use Softened Water: Utilize softened water in the cooling system to prevent scaling and ensure long-term efficiency of the condenser.
Benefits and Applications of Evaporative Coolers
With the increasing need for industrial cooling, evaporative coolers have been the ideal solution for the majority of workshops and factories. Evaporative coolers possess several advantages over traditional air conditioning systems in terms of cooling capacity, price, installation, and maintenance.
1. Environmentally Friendly and Energy Efficient
Evaporative coolers lack compressors and refrigerants. They function based on the indoor and outdoor air transfer to cool the air. This makes them very energy efficient and eco-friendly as they consume less electricity and produce fewer poisonous emissions.
2. Low Cost and High Return on Investment
Evaporative coolers are cheaper to install and run than traditional air conditioning systems. They have an instant payback, allowing businesses to save on overall operating expenses.
3. Effective Cooling Performance
Evaporative coolers have wide cooling advantages during hot and humid climatic conditions. They can operate under any climatic condition because of their unique mode of operation, and they make the indoor environment comfortable.
4. Space-Saving and Low Maintenance
Evaporative coolers take up much less space than standard air conditioning equipment, which can be a huge advantage in situations where space is limited. Further, they are easy to service and use and do not require much technical expertise for routine inspection and small-scale repairs.
5. Improved Air Quality Apart from cooling
evaporative coolers also improve indoor air quality by introducing fresh outdoor air into the room. Not only do you have a cooler room, but also fresher, cleaner air. Conclusion High-pressure alarms on chillers from excessive temperatures can be easily rectified by cleaning the condenser, improving heat dissipation, and routine maintenance.
In addition, evaporative coolers are eco-friendly and economical alternatives to traditional cooling systems. They are noted for energy efficiency, low maintenance, and effective cooling. With the right cooling equipment for their use, companies can achieve maximum temperature control with minimal costs and improved air quality.
