Commercial Chiller Inspection

Air Conditioning Repair


Malfunctions and issues with chilling equipment is not only a source of inconvenience for the owners but also hazardous to the occupants of the place. It is important to ensure the equipment is in proper working condition to avoid malfunctions.


A commercial chiller is the machinery used in the cooling process through two ways. They can cool by vapor compression or by a process named absorption refrigeration cycle. Vapor compression is used within the cooling process of large buildings and commercialized warehouses for storing frozen merchandise.


It is common sense to have the cooling system running and well maintained for health and safety reasons. The damage that can be caused from malfunctions can be costly and an increase in the expenses far much worse than the cost of maintenance. The process of maintenance involves scheduling random inspections regularly by professionals. Similar to any heating air conditioner, the chillers have to be maintained and serviced regularly. The process involves the following steps:


1) Dropping the head part of the chilling unit.


2) Thoroughly cleaning the brush tubes. This will ensure the tubes are able to transfer the heat better. Sufficient heat transfer enables chilling efficiency of the unit.


3) Oil analysis regularly. Take samples of oil at intervals when the chiller is running. These samples should then be run for tests to certify their efficiency.


4) Take samples of the refrigerant. Take the samples for testing, this sample can enable one to determine a lot about the chilling unit. Once a refrigerant is well charged there will be no leaks. If the refrigerant is incorrectly charged there will be malfunctions that may lead to damages within the unit such as the compressor impeller, the carryover of the refrigerant and a reduction in the capacity caused by an overloaded motor. The consumption of power will also be more than the required.


5) Randomly perform the Eddy Current Tests. The Eddy current test involves the use of an electromagnet that is not destructive. It uses the electromagnet principle of induction to operate. This process does not facilitate the release of hazardous chemicals or radiation. This process works best in non magnetic alloys, however.


6) Use water treatment. There should be water analysis performed monthly on your unit. This will help detect malfunctions and recommendations can be done accordingly. Choose water treatment options that are environmentally friendly and conservative.


7) Document all performance. The equipment should be monitored and performance noted down frequently. Comparisons of the documented performance and the start up data will enable detections of changes. Control measures can also be set based on the manufacturers list of performance measures. Any defaults and changes should be flagged from investigation. Smartphones can contribute greatly to the monitoring process using relevant apps.


8) Be ready for winter: It is advisable to ensure you maintain a 40 degree set on your systems to avoid freeze ups within your units. Randomly check the status of the dampers and the controls within the building, also protect the mechanical rooms sufficiently to prevent damages. This can be done by heating the room and proper heat insulation. It is important to have your chiller served regularly to enhance performance and safety.
