The reason why the chiller has insufficient cooling capacity or slow cooling

Industrial chillers are the necessary equipment for industrial production nowadays, and each unit is inseparable from the participation of refrigerants during operation. Therefore, the shortage of cooling capacity will affect whether the machine can operate normally. If something goes wrong, it will cause a lot of trouble for use. The chiller has insufficient cooling capacity, or the cooling and cooling is very slow. When we encounter these problems, what should we do? Let's analyze the shortage of industrial chillers and the reasons for the slow cooling.

The reason why the chiller has insufficient cooling capacity or slow cooling:

1. The occurrence of this situation is related to the large loss of cooling capacity. Due to insufficient insulation thickness of the equipment and pipelines or damage to the insulation layer, the loss of cooling capacity is increased, which affects the cooling effect. In operation, once the outer surface of the insulation layer is found to have wet or frosted parts, it means that the thickness of the insulation material is insufficient or has been wetted. In this case, the insulation material should be added or replaced in time. In addition, the evaporator tank cover is not tight, the air treatment room or the cold storage seal door seal is damaged, the air supply air supply duct and the room door and window leak. It will increase the loss of cooling capacity and take timely measures.

2. When each chiller is installed, a layer of insulation cotton is placed on the evaporator and the pipeline to prevent loss of cooling capacity. If the unit is slow in cooling, the company must first check whether the thickness of the insulation layer of the pipeline is insufficient or whether the insulation is damaged. Be sure to pack the insulation cotton and make sure the thickness is enough!

3. Check for air in the chiller refrigeration system. When installing a chiller, whether it is inside the unit, water pump, or pipeline, there should be no air, even if there is only a little air, the chiller is absolutely unable to operate normally. In addition, there is a film inside the pump, and you must remember to tear it off before installation. Otherwise, there is no way for water to circulate or flow slowly, which directly affects the operation of the chiller.

4. Check whether the moving parts of the refrigeration compressor are worn or the gap is increased, resulting in a decrease in the volume of gas. The compressor is the heart of the chiller. If there is a problem with the compressor, the chiller will not run 100%. Therefore, the periodic inspection and maintenance of the compressor cannot be ignored.

5. The poor efficiency of the refrigeration compressor is also one of the reasons. In the long-term operation of the equipment, the wear of the moving parts, the increase of the matching clearance or the tight sealing will reduce the actual air volume of the compressor and reduce the cooling capacity. Check the refrigeration compressor. If the repair is not good, it should be replaced in time. Air in the system can also cause this to happen. At this time, the exhaust pressure and temperature increase, the power consumption increases, and the cooling capacity decreases.

The above is the cause of insufficient cooling or cooling of the chiller. I hope to help everyone. If this phenomenon occurs in a chiller, it is generally inseparable from the above reasons. Of course, if you have not solved the problem after following the methods analyzed above, it is recommended that you directly inspect and repair the chiller manufacturer to avoid a wider range of failures.
