Get Yd Chiller Maintenance Requirements / Chiller Log Sheet (form 160.69-mr1)

Air-cooled Water Chillers Only Condenser fan inspections should be carried out with emphasis on bearings check for signs of wear, poor lubrication. Belts and couplings should also be checked and adjusted when necessary. Condenser coils should be inspected for leaks, corrosion, and areas of kinking or blockage.

Even the major manufacturers advise cleaning the chiller tubes as part of normal maintenance. In Carrier's operation manual for their AquaEdge® High-Efficiency Centrifugal Chillers they suggest “the following must be done on a yearly basis… shell and tube heat exchanger tubes [within the chiller] must be cleaned.”

Monthly chiller maintenance checklist Top up the lubrication if required. Check the condenser and clean the coils. Clean condenser water strainers. Run the chiller on full load and check the liquid level in the evaporator.

While HVAC systems are responsible for regulating the comfort levels of most indoor environments, a chiller plant act as a centralized cooling system which provides cooling for a building or a number of buildings. Additionally, it provides a portion of the air conditioning by HVAC systems.

Cleaning is a vital chiller safety practice because deposits can cause temperature increases, escalating the compressor burden to compress the refrigerant and block airflow. Daily inspection of winter chillers for leakages is essential to maximizing the equipment's performance and ensuring improved system operation.

Chillers should be tested for leaks, control operation and water quality weekly as well. Items such as load balances and limits can be inspected twice a year. A thorough cleaning, electrical system inspection, and other maintenance tune-ups should be performed annually.
