What are the operating specifications that need to be familiar with the cooling and heating cycle integrated machine

In the integrated cold and heat cycle machine, the main function of the heat exchanger is to transfer heat from the fluid with a higher temperature to the fluid with a lower temperature, so that the fluid temperature reaches the specified index of the process to meet the needs of the process
.


Similarly, parameters such as the flow rate, working temperature, and pressure of the heat exchange medium are also very important in the selection.
For example, although the plate heat exchanger is compact and has good performance, due to the limitation of the structure and the performance of the gasket, when the pressure or temperature is slightly higher , or it is not applicable when the traffic is very large
.

1.
Try to avoid restarting the cooling and heating cycle integrated machine within five minutes after it stops, so as not to increase the mechanical load of the refrigeration system compressor and affect the service life of the unit
.

2.
It is strictly forbidden to test flammable, explosive, volatile and corrosive items, otherwise it will cause an accident and cause damage to the machine
.

3.
The door of the box should be closed well and tightly before operation, otherwise it will cause the gas leakage of the studio, which will not meet the performance requirements
.

　　4.
Personnel should operate the integrated cooling and heating cycle machine to avoid unnecessary damage due to irregular operation
.

　　5.
During operation, please do not touch and check the parts of the machine system with your hands, so as to avoid electric shock or the accident of motor strangulation; therefore, please stop the machine and turn off the power before repairing
.

　　6.
The controller adopts color LCD man-machine touch dialogue type LCD man-machine interface controller, which is simple to operate, easy to learn, stable and reliable, and displays the complete system operating status, execution and setting program curve in Chinese and English
.

　　7.
Fully automatic, with PLC locking processing, all using PID automatic calculation control, high temperature control accuracy
.

　　8.
It can realize automatic operation, realize automation, reduce the workload of operators, and can automatically start and stop working at any time
.

　　9.
Status display and curve display during operation.
When abnormal conditions occur, the screen will automatically display the fault point and cause and provide methods for troubleshooting.
When it is found that the input power is unstable, it has an emergency stop device
.

10.
Safety protection function: power overload protection, leakage protection, control circuit overload, short circuit protection, compressor protection, grounding protection, over temperature protection, alarm sound prompt
.
