How to Maintain Your Chiller is not cooling? It is a significant matter in industrial buildings with different types of chillers. Since chillers are essential for performing a wide range of processes at the correct temperatures.
The right operation and maintenance approach should be prioritized by operators to improve system performance, guarantee a long lifespan, and save energy costs. Common chiller problems are described, as are their solutions, and troubleshooting assistance is emphasized.
Why the chiller is not cooling?
What is a chiller? Every day, industrial chillers will experience both major and minor malfunctions, and alarms will be triggered for the latter. But some won't sound the alarm; how do we identify if any chiller is not cooling enough?
Why isn't the chiller working, and the chiller is not cooling fix and what could be causing it? The following procedure is also applicable when the chiller is not cooling.
When a chiller malfunctions, Here are chiller repair solutions:
- If the chiller isn't doing its job, which is to remove heat from a room or process, then there could be some causes.
- One possibility is a refrigerant leak, which might cause a decrease in cooling capability.
- A defective Chiller compressor type, which moves the refrigerant and facilitates heat transmission, is another typical issue. Problems with airflow, such as blocked filters or broken fans, can also reduce the effectiveness of the cooling system.
- To restore the chiller's cooling functionality successfully, these concerns must be addressed without delay by calling in a trained expert to diagnose and fix the problem.
- The unit is too small and the power is not enough
If the brand-new machine you just got won't cool or if the water temperature won't go down, it's probably because your freezer doesn't have enough cooling capacity. For the time being, a larger chiller can serve as a suitable replacement.
Why isn't the chiller working, and what could be causing it?
- Long periods have passed without the condenser being cleaned.
One of the essential parts of a refrigerator is the condenser. The calcium and magnesium ions and acid carbonate are found in most cooling waters. Carbonates form on the metal's surface when cooling water flows over it. Corrosion and rusting of metals can also be caused by the oxygen present in the cooling water. Rust formation reduces the condenser's heat exchange efficiency and hence its ability to cool.
- We have a clogged dry filter.
If the drying filter becomes clogged, the condenser's ability to exchange heat is compromised, which in turn reduces the overall cooling capacity of the machine. This means the filter needs to be checked and cleaned frequently. If the clogging is severe, you should get a new drying filter.
Using tap water that isn't clean
Tap water's impurities cling to the tank's inner wall and the pipe, decreasing water flow and nullifying the cooling effect. The water pipe or the chiller itself should be cleaned and replaced regularly if you reside in an area with poor water quality.
Low levels of refrigerant (also known as freon or refrigerant)
R22, R410a, R407c, R134a, etc. are all common refrigerants. Liquid refrigerant in the evaporator is constantly absorbing heat from the water as the chiller or air conditioner runs.
The air is compressed as it travels through the compressor and then expands when it exits the valve. Following the first flow, the evaporator converts the fluid into a low-temperature, low-pressure refrigerant for further circulation.
The cooling effect will diminish if the appliance is operated for too long and the refrigerant evaporates. Currently, the user's only responsibility is to add refrigerant correctly; nevertheless, poor installation can lead to leaks of both freon and the machine itself.
The temperature outside is excessive.
Air-cooled chillers and air conditioners have trouble transferring heat to the outdoors when the indoor is airtight or when the temperature is over 40 degrees Fahrenheit, resulting in no refrigeration and possibly even a compressor high-pressure alarm.

There hasn't been regular cleaning and maintenance of the ice maker.
The cold water unit readily absorbs dust and dirt after prolonged use. The machine's heat dissipation efficiency will suffer if it isn't cleaned regularly.
Scale builds up in the pipes, which in turn fosters bacterial growth and diminishes the cooling capacity. Therefore, routine cleaning and upkeep of the machinery and pipelines is essential.
The chiller or air conditioner will fail to cool if the voltage supplied is insufficient, and the copper pipes connecting the indoor and outdoor units are too long.
It's also possible that the chiller's temperature sensor is broken if the real water temperature has attained the standards but the temperature on the display screen has not reduced. The temperature sensor is all that needs fixing here.
Thus, many factors can prevent the water chiller not cooling. These are common failures that the user's intended use should guide the maintenance staff's decision.
