Reasons for the temperature reduction of the tank water chiller
In the process of using the box chiller, it will inevitably show some problems as the machine wears and ages. So when the temperature difference between the inlet and outlet water is too small, what should we do? For example: when the user encounters this situation when using a box-type chiller, the current inlet water temperature is 20°C, and the outlet water temperature is 18°C. The temperature difference is too small to meet user needs. Regarding the reasons for the small temperature difference between the inlet and outlet water, there are mainly the following situations:
1. It may also be that the heat transfer effect is not good. For example, the heat transfer tube has serious scaling and affects the heat transfer of the chiller. This can be judged by observing the heat transfer temperature difference between the water temperature and the evaporation temperature.
2. The output cooling capacity of the box-type chiller is small. For example, the unit itself is faulty or not fully loaded. These can be preliminary judged by observing the operating current of the chiller.
3. The water flow is too large. This can be judged by observing the pressure difference between the inlet and outlet water pressure of the evaporator and the running current of the water pump.
4. After removing the above problems, let's see if the sensor or thermometer is not accurate.
If all the above steps are completed and we still cannot detect the fault of the box-type chiller, then we should contact the chiller manufacturer or find a professional engineer to deal with the problem.
