How to solve the small temperature difference between the inlet and outlet water of chiller industrial?
The LC -25°C ~ -5°C Low Temperature Chillers may experience wear and tear during use, so we need to regularly record and analyze its operating parameters, observe the sound emitted during operation, check the specific conditions of the refrigerant and refrigeration oil, and carry out regular maintenance operations.
Professionals who have been specializing in industrial refrigeration, commercial central air conditioning, and industrial dehumidification equipment for many years have analyzed the reasons for the small water temperature difference between the inlet and outlet of chillers.
The professional stated that users sometimes encounter this situation when using a chiller: when the chiller is in operation, the current inlet temperature is 24 ℃ and the outlet temperature is 23 ℃. The temperature difference is too small to meet the needs of users. The reasons for the small temperature difference between import and export are as follows:
1. The output cooling capacity of the chiller is small. If the unit itself malfunctions or is not fully loaded, preliminary judgment can be made by observing the operating current and other parameters of the chiller.
2. It is also possible that the heat exchange effect is not good, such as severe scaling of the heat exchange pipe, which affects the heat exchange of the chiller. This can be determined by observing the difference in heat transfer temperature between water temperature and evaporation temperature.
3. If the water flow rate is too high, it can be determined by observing the difference between the inlet and outlet pressure of the evaporator and the operating current of the water pump.
After eliminating the above issues, it is possible to consider whether the sensor or thermometer is inaccurate.
The box chiller unit itself has a fault problem, and the output cooling capacity of the unit itself is small. These issues arise. You can check the operating current parameters of the chiller to make a judgment.
The evaporator has scaling, which leads to poor heat transfer and affects the heat exchange of the entire small chiller. We can make a judgment by checking the heat transfer temperature difference between the water temperature and the evaporation temperature.
The sensor and thermometer have malfunctioned, resulting in temperature difference issues. Check and replace the sensor and temperature gauge.
