What is the reason why the chiller is not cooling?

Industrial chillers will inevitably have large and small faults in the daily operation process, and general faults will have alarm prompts. But some will not alarm, so how to determine and eliminate the fault? What is the reason why the chiller not cooling? Today I will briefly talk about the reasons and solutions for the chiller not cooling. The following method is also applicable when the chiller not cooling.

When a chiller not cooling properly, it can be indicative of a potential issue within the system.
The chiller's primary function is to remove heat from a space or process, so if it fails to provide adequate cooling, several factors may be at play.
1.One possibility is a refrigerant leak, which can cause a decrease in cooling capacity.
Another common problem could be a malfunctioning compressor, which is responsible for circulating the refrigerant and facilitating heat transfer. Insufficient airflow due to clogged filters or damaged fans can also hinder the cooling process.
It is crucial to address these issues promptly by contacting a qualified technician to diagnose and resolve the problem to restore the chiller's cooling functionality effectively.

2.The ambient temperature is too high

When the indoor is airtight or in an environment above 40°C, it is difficult for the air-cooled chiller or air conditioner to transfer heat to the outdoor, which leads to no refrigeration and even a compressor high-pressure alarm.

3.The cold water machine is not cleaned and maintained for a long time

After using for a period of time, the ice water unit is easy to absorb dust and debris. If it is not cleaned for a long time, it will affect the heat dissipation performance of the machine. The pipes are also prone to scale, breed bacteria, and reduce the cooling effect. Therefore, the equipment and pipes need to be cleaned and maintained regularly.

Insufficient power supply voltage and too long copper pipes connecting the indoor unit and the outdoor unit will also cause the chiller or air conditioner to not cool. In addition, if the actual water temperature has reached the requirements, but the temperature on the display screen has not decreased, it is likely that the temperature sensor of the chiller is damaged. In this case, you only need to replace the temperature sensor.

In short, there are many reasons why the chiller or air conditioner is not cooling. The above are common types of failures. The specific situation requires the maintenance personnel to judge according to the actual use of the user.
