What are HVAC Chillers?

Air conditioning is an integral part of every commercial, residential and industrial set up. For smaller structures, separate AC units are required, but, a centralized air-conditioning system is crucial for larger one. In such centralized systems, giant AC units – chillers – are used to provide the cooling for industrial and commercial applications. With the increase in large structures and industries, there’s a need to make every product cost-effective; hence, chiller operation and maintenance in India have become extremely important.

How do HVAC chillers work?

HVAC chillers usually generate chilled water to provide air conditioning in large industries with centralized cooling system. These structures generate a lot of unwanted heat, from both solar heat gain and from the electrical equipment in use. To remove that heat and help everyone live in a comfortable temperature, chillers work in such a way that they ensure proper maintenance of the equipment.

Chillers are either located in the basement or on the roof of industries. Ones on the roof are generally air cooled, while the basement chillers are generally water cooled. That is, they use cooling towers or condenser (like in normal AC units) to disperse the unwanted heat into the atmosphere and comfort workers.

Air compressor operation in India has been gaining ground, lately, due to the excessive rise in temperature and growing discomfort with the heat. Chillers use a refrigerant gas that moves the heat between the evaporator and condenser. The evaporator generates chilled water, which is sent around the industrial structures by a pump to collect the heat and bring it back to the evaporator to be cooled down. The refrigerant collects this cooled-down heat, moving it to the condenser. Now, the condenser puts it into another loop, and sends it to the cooling towers, and into the atmosphere.

HVAC chillers include microprocessor controls and integral pumps that improve the overall chiller performance by improving its integral pumping capacity with precise programming.

Best Guidance To Care & Maintain Industrial Chillers

Chillers actually act as a plant’s single largest electrical load supplier. Maintenance works of the chillers involve repairing and cleaning of tubes and ducts, repairing and preventing the leakages of refrigerants, decreasing the operating cost and saving energy. Chiller operation and maintenance in India has reached a new height after the latest developments in centrifugal chillers and magnetic bearing chillers. Latest remote monitoring technologies also help a lot.
Our company Energy Plus India acts as a mechanical project company to provide utility services. So, as an expert here,

We will point out by what techniques you can maintain industrial chillers.

MAINTAIN LOG
If you keep daily or periodical records of temperatures, pressures, levels of fluids and residual precipitation, then this history of operating details will help you understand as to how and when you should maintain your chiller. You can use remote monitoring technologies for continuous monitoring.

KEEP THE TUBES CLEAN
To get high performance, you need to ensure that the heat transfer through the pipes remains efficient. Make sure that there is no dirt, residual minerals, ores, mud, scale, algae present in the pipes. Approach temperatures indicate heat transfer efficiency, and higher approach temperatures indicate that heat transfer is not efficient. You must clean the condenser tubes at least once a year.

TREAT CONDENSER WATER
Condenser water loops use open cooling sources to cool; such water needs to undergo treatment to remove scale, residue, and biological dirt. Otherwise, heat transfer will be affected and the effectiveness of pipes and ducts will decrease. Inspect chilled water loops at least once a year.

ENTERING WATER TEMPERATURE SHOULD BE LOW
If you keep the entering water temperature low, then your chiller’s efficiency will increase.

CHILLED WATER FLOW RATE
Chilled water flow rate affects the efficiency of a chiller. Low flow rate decreases the efficiency. The minimum flow rate should be approximately 3-feet per second (FPS). High flow rate causes vibration, noise, and erosion of tubes. The maximum flow rate should be approximately 12 FPS.

MAINTAIN REFRIGERANT
Amount of coolness of a chiller depends on the amount of refrigerant which passes through the compressor. Prevent the leakage of refrigerant and prevent air and moisture, which will cause increased efficiency.

MAINTENANCE OF HARDWARE
Analyze the lubricating oil of the compressor once a year. If necessary, then change the oil. You need to prevent high moisture to improve purge run hours. Check the oil filters, and if the pressure drops, then you need to change them. You don’t need to take this headache for magnetic bearing frictionless chillers.
Regularly check and remove faults from the entire electrical system which involves starters, gears, motors, wiring etc.

SPEED DRIVES
You can install variable speed drives to save energy. These drives match the motor efficiency and lower the inrush current during starting of motors.

Tips To Keep Your Boiler Operation Healthy And Functional

Industrial boilers are pressurized systems that burn combustible fuel or use electricity to heat water that is used to provide heating in your building. Certain steps are necessary to keep your boiler operation healthy and functional. We at Energy Plus, a trusted provider of Boiler Operation & Maintenance in India are providing you some tips in order to help you take care of your boiler:

Keep up the pressure
The boiler and the rest of your heating system will lose pressure over time. Your system needs the right amount of pressure to operate properly; too low and your boiler won’t fire up; too high and there’ll be the excess strain on the pipes and equipment. Just check the pressure gauge on your boiler regularly. The gauge should be pointing between 1 and 1.5 bars. If it falls below this, you’ll need to top up the pressure of your boiler. Each boiler will have particular ways to increase the pressure, so consult the instruction manual.

Arrange for an annual service
You should get your boiler and heating system serviced at least once a year. At some time, you’ll need an annual boiler servicing to keep the warranty valid. Regular boiler checks will help it to run smoothly and safely.

At Energy Plus, we understand the value of maintaining the boiler and is always prepared with any kind of boiler operation and maintenance in different cities in India.

Effective Tips on the Way to Care and Maintain Industrial Chiller

Industrial chiller is very important for the proper functioning of a factory. Chillers get congested at times and create huge nuisance in industry operations.

These essential tips will help you eradicate problems with chillers –

Keep a daily log

Keeping a daily log is essential for any industrial heavy equipment. Always have a data ready for your chillers. Parameters like temperature, pressure, fluid levels and flow rates should be recorded and monitored. These will come in help during maintenance and repair. Remote monitoring technologies will allow you to inspect your machines periodically. It will also allow you to generate trend reports that can pinpoint functional problems.

Keep tubes clean

This is crucial for effective heat transfer. Condenser tubes should be cleaned at regular interval. Industrial Chiller performance will be greatly compromised if the heat transfer is interrupted by contaminants. Cleaning ensures that the tubes remain free of sludge, mud, scale, algae, dust and other contaminants.

Treat condenser water

Condenser water loops that uses open cooling sources requires water treatment to stay free from corrosion, scale and biological growth. The water quality should be well monitored to ensure proper chilling and heat transfer.

Decrease entering water temperature

Decreasing the temperature of the entering water increases chiller efficiency. Keeping the chilled water flow between 3 to 12 feet per second ensures better efficiency.

Maintain proper level of refrigerant

Keep the refrigerant level as per the chilling requirements. Too low or too high level of refrigerants is detrimental for the health of chillers.

Check compressor oil

Send compressor oil samples to laboratories to check its quality. This spectrometric analysis reveals a lot about the overall health of the chiller. Change the oil when the reports indicate anything wrong.

Install variable speed drivers

As the chillers have huge electrical intake, VSD should be installed for electric saving. This also prevents electric charge overflow.

Chillers in most cases represent the single largest electric load in a plant. Hence, proper chiller maintenance is very important too keep it light on pocket. At Energy Plus, we offer best of its kind chiller operation and maintenance in India to give you a smooth factory experience.
