Why is the temperature difference between the inlet and outlet water of the ማቀዝቀዣ too small?

The main reasons for the small temperature difference between the inlet and outlet water are as follows:

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

2. It may also be that the heat transfer effect is not good. For example, the heat transfer tube has serious fouling, which 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.

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 water pump.

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

The technical staff said that under normal circumstances, if the chiller fails, you should directly communicate with the manufacturer on the phone to confirm what the fault is. The user can solve the small faults that can be solved by themselves. If it cannot be solved, it is recommended that the chiller manufacturer arrange after-sales Service personnel come to conduct inspections and perform comprehensive maintenance on the unit.
