Analysis of Heat Transfer Oil in Refrigeration and Heating Systems
The refrigeration and heating system is also called high and low temperature circulation device or cooling and heating circulation integrated machine. It is a temperature control equipment used in the supporting reaction kettle of the pharmaceutical and chemical industry to provide cold source and heat source. The heat transfer medium selected by the refrigeration and heating system is heat transfer oil. According to the equipment Different models, you can choose different models of heat transfer oil.
1. Application of heat transfer oil in refrigeration and heating system
Heat transfer oil is divided into different models according to different temperature ranges. It is recommended to select the appropriate heat transfer oil according to the temperature range of the equipment model. Due to the difference in equipment configuration, the heat transfer oil consumption of different refrigeration and heating systems is different. If it is a fully closed circulation pipeline, there will be no water vapor and oil mist, and the amount used will be less than that of an open refrigeration and heating system.
The heat transfer oil has been used at high temperature for a long time. If it is an open equipment, its quality will be affected to a certain extent. It is necessary to regularly test the heat transfer oil of the refrigeration and heating system to check whether there is sediment in the oil quality. If it is a fully closed cycle In the refrigeration and heating system of the pipeline, the heat transfer oil does not participate in the circulation, and the inspection time can be appropriately relaxed. After the oil quality changes, it is necessary to replace the heat transfer oil with new ones.
2. The quality of heat transfer oil in the refrigeration and heating system
The heat transfer oil of the refrigeration and heating system is generally analyzed from four aspects: viscosity, flash point, acid value, and carbon residue. Generally speaking, if the quality of the heat transfer oil of the refrigeration and heating system changes, its viscosity will change. If the oil is polluted or oxidized, the operator needs to replace it in time. If the heat transfer oil is corroded, check the residual carbon value, and pay attention to it after it is higher than the average value. If these four items of data do not exceed the range of change, it means that the quality of the heat transfer oil in the refrigeration and heating system is good and it can still operate normally. If one of the data is abnormal, it is necessary to consider taking corresponding measures to replace the heat transfer oil in time.
3. Precautions for the use of heat transfer oil in refrigeration and heating systems
The environment for heat transfer oil and cooling and heating systems should be ventilated. Although the heat transfer oil has a high boiling point, open flames should be avoided. Once the heat transfer oil leaks, it will cause accidents if it comes into contact with an open flame. At the same time, care should be taken not to place it in the hot gas flame zone and avoid the source of ignition.
