َAll about Common Chiller Problems & Troubleshooting

Cold Direct chiller problem troubleshooting in London

All of you definitely know what a chiller is, and that is why you navigate to this article that discusses common chiller problems.

Industrial chillers use a lot of power, but they are necessary for various activities that require specific temperatures. Operators must emphasize the optimal operation and maintenance approach to maximize system performance, maintain a long lifespan, and reduce energy costs.

Here, we want to address common chiller problems and then express the water chiller troubleshooting.

Chiller Problems and Solutions

faults or performance issues are detected for all Types of Chillers. These codes are usually quite specific and will hasten the troubleshooting process. Here, we have both problem and solution categories.

7 common chiller problems

Find out here what issues typically arise with chillers and how to fix them. Here are the top common chiller faults.

The Chiller is not holding the temperature

There is a risk that the temperature of the process will rise above the value that the chiller system can maintain. An alarm will sound when the system detects a heat load that exceeds the Chiller's capability. The chiller system's warning for excessive heat could also go off if set lower than usual.

Improper Operation

Industrial chillers include user manuals that detail the manufacturer's recommendations for optimal performance. Operators are obligated to follow these guidelines since improper use of equipment shortens its useful life and decreases its efficiency.

Although poor maintenance procedures do not necessarily render these cooling systems inoperable, it is essential to recognize that they become increasingly vulnerable to costly and dangerous issues. Implementing training programs on correct chiller operation and maintenance and establishing effective chiller maintenance procedures to counteract this risk is essential.

Maintenance Neglect

It is possible for chiller performance to suffer and energy consumption to rise if operators don't execute the suggested maintenance. Maintaining efficient operations requires proper diagnosis of equipment based on historical data. Chiller units also require frequent inspections to ascertain their condition and organize preventative and corrective maintenance.

Incorrect Sizing

When designing a cooling system for a factory, one of the first things to consider is the size of the Chiller. Inadequate equipment sizing might result in inefficient airflow and cooling. However, oversizing severely constrained low-load operations, leading to higher costs overall. Operators must evaluate the chilling capability of currently installed chillers to determine if they are enough for typical cooling demands.

Clogging problem

Heavy cylinder wear or excessive cylinder clearance might cause premature compressor failure. Because oil has a higher viscosity than gasoline, it is discharged into the condenser along with the refrigerant, clogs the filter drier's entrance, and prevents the refrigerant from circulating normally.

If there is still too much refrigerant oil in the water chiller system, the cooling effect will be nullified, and the system will not be able to function correctly.

Water leakage

The pump is dripping (either due to a loose connection or damage to the shaft seal).

Faulty Compressor

Different chiller compressor types

can prevent the Chiller from circulating refrigerant, rendering it ineffective. This problem can be solved by having the compressor repaired or replaced.

Chiller Surge

A Chiller surge occurs when the amount of cooled water flowing through the Chiller surges below a given threshold. Many things can cause this, such as malfunctioning control valves or pumps, abrupt shifts in load demand, or alterations to the system's structure.

3 Air-cooled chiller troubleshooting

Here are some of the important chiller troubleshooting checklists that Cold Direct is taking the responsibility of all as well as possible.

The Chiller is not cooling

A frozen evaporator or deteriorating coolant fluid could be the cause of this issue, which can be diagnosed by testing the coolant temperature at the chiller outlet.

Insufficient Pumping

An insufficient coolant volume, a partially closed valve, a faulty pump, or constraints in the process line can all lead to a lack of pumping. Due to these reasons, the refrigeration cycle's coolant flow may be severely impeded.

Regular Maintenance

It is important to do routine maintenance checks as part of your daily monitoring routine. You can potentially avoid a lot of downtime by performing these tests for only a few minutes daily.

Maintain a daily log sheet to record whether or not inspections and maintenance have been performed. Technicians need to keep track of who conducted maintenance and when. The most important thing is to keep track of every aspect of care, no matter how minor (such as adding oil, for example).

More thorough inspections should be carried out once a week or once a month. You must open up the Chiller's cabinet to do these tests.

If your Chiller is only utilized for part of the year, you should give it a thorough once-over at the beginning of the season and again just before you turn it off for the year.

How can ColdDirect Help you with Chiller problems?

While it's impossible to know exactly when your Chiller may fail, there are a few warning indications you can watch out for.

  • Historical Efficiency of the Chiller
  • Age of the Chill
  • Neglected Upkeep
  • Oversizing / Undersizing
  • Idle Time
  • Poor Operating Procedures
  • Ignoring Cooling Towers
  • Lack Of Maintenance
