In the pharmaceutical, food, chemical and other industries, process water cooling and cooling are required. The chiller has become a must-have device for many industries. Knowing the operation of the equipment and performing the correct operation is a prerequisite for ensuring smooth operation of the equipment. What should I do if the temperature difference between the inlet and outlet of the chiller is small?
When the user uses the chiller to encounter this situation: the company uses a chiller, the current inlet water temperature is 24 ° C, the outlet water temperature is 23 ° C, the temperature difference is too small, can not meet the needs of users. For the reasons why the temperature difference between the inlet and outlet water is too small, there are mainly the following situations:
1. The output of the chiller has a small amount of cooling. For example, the unit itself has a fault, or it is not fully loaded. These can be judged by observing the parameters such as the chiller operating current.
2. It may also be that the heat transfer effect is not good. For example, the heat transfer tube is seriously fouled and affects the heat exchange 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 rate is too large. This can be judged by observing the 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 thermometer is not accurate.
