Precautions for the use of fluid heating and cooling systems

Fluid heating and refrigeration system temperature control, fluid heating and refrigeration system is what we often call closed refrigeration and heating cycle device, also called high and low temperature integrated machine, cold and heat integrated machine, and various types of glass reactors, double-layer reactors, reactors , extraction equipment and other devices cooperate to achieve the same machine operation of cooling and heating
.

1.
Whether the fluid heating and cooling system is air-cooled or water-cooled, the temperature control device should be located in an operating environment with sufficient fresh air: the surrounding space is greater than 30cm
.

2.
When selecting the heat transfer medium of the refrigeration constant temperature circulator, pay attention to whether its temperature upper and lower limits, ignition point, viscosity, freezing point, etc.
meet the requirements, and whether it is suitable for the use of the internal pipeline of the instrument
.

3.
The cooling and heating circulation device of the reaction kettle of the fluid heating and refrigeration system adopts suitable instruments, and it is strictly forbidden to vibrate violently during installation
.

4.
The fluid heating and refrigeration system needs to be heated frequently
.

The temperature measuring instrument should be checked and measured regularly to prevent inaccurate temperature and misoperation caused by the large thermal resistance of the temperature measuring node
.

　　5.
The user should customize detailed operating procedures and regular maintenance system, and the operator should be very familiar with and master the operation of the equipment
.

　　6.
It is especially suitable for the control of heating and exothermic processes in the reaction process
.

The installation of the circulating pipeline of the fluid heating and refrigeration system should facilitate the discharge of the gas in the pipeline
.

If there is leakage, stop the operation in time and use it after repair
.

　　7.
The heat transfer medium of the heating and cooling constant temperature circulator is not suitable, which will have a negative impact on the equipment and may cause damage to the equipment
.

　　8.
Within the specified pressure range, only the heat transfer medium specified by the manufacturer can be used
.

　　9.
When controlling the temperature of the fluid heating and refrigeration system, it is necessary to quickly and effectively compensate for the heat absorption and heat release in the chemical reaction.
When choosing a suitable temperature control system, various conditions and influencing factors need to be comprehensively considered
