How to Troubleshoot an Industrial Chiller

Industrial chillers are heavy duty air-conditioning units meant for use in situations where excess heat generation can become a serious problem; for example, in computer processing rooms, where it is important units do not overheat. Regular maintenance is important so that you avoid malfunctions. It's a good idea to have some base knowledge of the preventative measures you can take. Regardless of how careful you are, there are some things that can go wrong, but before you talk to an engineer there are some ways you can troubleshoot.

Instructions

- 1
  Check that the unit connects to a working source of power if you are getting no response from the unit. Also check whether the circuit breaker governing that power source has tripped (if so, reset it) and look for any loose connections or wires that appear to be damaged.
- 2
  Add fluid if the refrigerant levels are too low, indicated by a loss of charge as the compressor cycles run. You should also add refrigerant if the expansion valve starts to hiss.
- 3
  Look for vibrating pipes as the industrial chiller runs its normal cooling cycle. This could indicate unsupported or badly fitting and loose pipes. Visually inspect the unit for loose pipes and have an engineer replace them.
- 4
  Look around the base of the machine for any sign of fluid leaks. If there is oil seeping from the chiller, this indicates broken seals somewhere on the unit. Trace the leak back to the source if possible and replace the seal.
