HELPING YOU ANSWER COMMON CHILLER QUESTIONS

Do any of these questions seem familiar?

  • How many tons/kw of cooling is my chiller actually giving me?
  • Is it still capable of delivering the capacity it was designed for?
  • How efficient is my chiller at the moment?
  • Why can’t my chiller achieve my set point?
  • Is it using more power than it should?
  • What can I do to my chiller to save more power?
  • Is my chiller healthy?


Frequently Asked Questions

What is CheckMyChiller.com?

A free tool that helps answers these type of questions, and provide you with the means of doing a quick health check on your chillers.

Who is CheckMyChiller.com for?

This tool is for anyone that can stand in front of a chiller. You don’t need to understand chillers well to use this tool, simply key in the information provided on the chiller control panel, and the tool will do the rest.

What Chillers can CheckMyChiller.com be used on?

CheckMyChiller.com can be used for any brand chiller, water cooled, or air cooled, flooded or DX, but is currently only set up to allow chillers that have R134a, R123, or R22 as refrigerants. If you have a chiller that has a different refrigerant, please let us know the details and we will try to make the tool available for your chiller model.

When should you use CheckMyChiller.com?

Anytime you have one of the questions above, simply login, input the data, and get your answers. The more you use it, the more powerful it becomes, as you can begin to see trends, and notice changes over time. Use it before a chiller fails, as chillers can often run reliably, while still consuming far too much power for the amount of cooling they are delivering.

Why should I use CheckMyChiller.com?

Chillers are extremely power hungry, typically using about 35-50% of the buildings total power consumption. Studies have proven that the performance of a chiller and its capacity, always degrades over time, and you may have lost 30% of your chillers capacity, and added 15% to your buildings power bill without even knowing it. This tool will help you identify if your chiller is not as healthy as it should be, and just how unhealthy it is.

How will I know if my chiller is healthy?

CheckMyChiller.com can provide you with a chiller health score, indicating that either your chiller is doing great (hopefully), or that it is unhealthy to a certain degree, in which case it will also provide you with some possible causes for the issues it has identified.

Just how accurate is CheckMyChiller.com?

The results provided by this tool are only as accurate as the data you enter. To try make it as accurate as possible, it will give you an indication when the data you enter is unusual, and prompt you to double check your figures before drawing any conclusions about your chillers health. This tool is intended as a guide only, and is no substitute for a Central Plant Energy Control System, equipped with flow meters, and highly calibrated temperature sensors, but it will point you in the right direction, and at least flag if there is an apparent issue without going to significant expense to do a full energy audit, or equip your plant with high end monitoring equipment.

What can make my chiller unhealthy?

There are numerous factors that can affect the health of your chiller, but here are some of the more common ones:

  • Heat Exchangers become fouled, due to sludge, mud, scale, biological growth or other contaminants found in the water, which tend to accumulate over time on the water side of the heat exchanger tubes, most commonly in the condenser, but sometimes also in the evaporator.
  • Water Flow Issues, on either or both the Chilled and Condenser Water side.
  • Compressor Degradation over time due to wear.
  • Internal Heat Exchanger Fouling, typically due to the presence of oil, or other contaminants, that can build up on the refrigerant side of your evaporator and condenser tubes.
  • Chiller Refrigerant Control, sensors may be out of calibration, Expansion Valves may be faulty, Hot Gas Valves may not be fully sealing, resulting in refrigerant in the wrong place at the wrong time.
  • Other Refrigerant Issues, such as refrigerant leaks, incorrect charge either too much or not enough, or the presence of a non-condensible, such as air present in the chiller.
  • Issues with chiller and plant settings, such as water temperature set points, Refrigerant control settings, compressor management, cooling tower operation, pumps, bypasses, etc.

If CheckMyChiller.com finds a problem, can it be fixed?
