What to Do if the Chiller Temperature Difference becomes Smaller?

Feb. 10, 2020

Today, the Water Chilling Machine Manufacturer will introduce how to deal with the difference between the temperature of the water entering the chiller and the temperature of the water coming out of the chiller.


1. The output cold capacity of the chiller is small, such as the unit itself is faulty, or is not fully loaded, etc. These can be preliminary judged by observing the operating current of the chiller unit and other parameters.

2. It may also be that the heat transfer effect is not good. For example, the scaling of the heat transfer tube is serious and the heat exchange of the chiller is affected. This can be judged by observing the heat transfer temperature difference between the water temperature and the evaporation temperature.

3. The water flow is too large. This can be judged by observing the pressure difference between the inlet and outlet water of the evaporator and the running current of the pump.

4. After eliminating the above problems, you can consider whether the sensor or the thermometer is inaccurate.


If all the above steps are completed and we still cannot detect the failure of the chiller, then contact the manufacturer or find a professional engineer to solve the problem.


For chiller units, such as the Water Cooled Chiller Machine, if they are operating at high temperatures, it may lead to severe loss of cooling air for a large number of chiller units. After ensuring the sealing effect of the use environment, the industrial water cooler can be effectively and timely insulated to ensure that the industrial water cooler is in a stable operating state. The chiller operating efficiency is stable, which can improve the unit's environmental cooling efficiency and reduce the energy consumption of the chiller.

The insulation of industrial water coolers must be done by professionals. Because the internal components of the chiller can be insulated in many places, many places cannot be insulated. Therefore, when the equipment is insulated, it must be carried out under the guidance of professionals. The better the insulation effect, the higher the safety of the chiller in the later period, which can reduce the probability of the chiller's failure and prolong the service life of the chiller. For a long time, the use of industrial chillers has greatly helped enterprises.


Note for chiller:

In order to obtain better treatment results, companies must choose high-quality insulation materials when completing the heat treatment of the chiller. Because the cost of different insulation materials is different, choosing a product with low price and good insulation effect can reduce the insulation cost of the chiller. Only the chiller insulation material used can successfully complete the entire insulation process, provide a more comfortable operating environment for the chiller, and avoid the impact of various faults on the chiller.


In order to ensure the safe and stable operation of the chiller, comprehensive insulation must be performed before using the chiller. Regardless of the location of the chiller's pipes or various parts, as long as it can complete the position of heat insulation, all the insulation is performed, thereby improving the operating safety of the chiller. Reduce the probability of various failures of the refrigerator to achieve higher operating efficiency and meet the needs of enterprises for industrial refrigerator operation.


The above is the method introduced by Air Cooled Chiller Manufacturer to deal with the decrease of the temperature difference between the inlet water temperature and the outlet water temperature of the chiller. I hope it can help everyone.
