Advantages of Parallel Chillers

1. According to the number of equipment turned on and the cooling capacity required by the equipment, the number of compressors to be turned on is automatically selected, which greatly saves energy, and saves more than 20% of electricity compared with units of the same power.

2. Compact structure: compressors, accumulators, gas-liquid separators, etc., including electronic control equipment, are all centralized together, with a highly integrated design concept.

3. If one mainframe fails, other mainframes can still supply cooling intermittently to reduce losses.

4. Automatically select the host with short cumulative working time to boot first each time it is turned on, to ensure that all the hosts have the same working time, and can avoid frequent startup of individual hosts through fuzzy control, greatly extending the service life of the host.

5. The PLC control has high stability, ensuring that there will be no failure in electrical control during long-term operation.

6. PLC control can truly realize that the refrigeration system does not require professional management, and can realize remote temporary control, which can temporarily control the working conditions of any equipment at any time in the main engine room.

7. The color touch screen man-machine interface allows users to set the working parameters of each device and the host more easily.

8. The PLC control has high stability, ensuring that there will be no failures in electrical control during long-term operation.

9. Equipped with phase loss, phase sequence, voltage, oil pressure, liquid level, high voltage, low voltage, motor overload, protection module, oil flow protection, air circuit breaker protection and other protections, and automatically handle alarms according to the protection level, if necessary Intervention staff.

10. PLC control can truly realize that the refrigeration system does not require professionals to manage it. It can be realized that the operation of any equipment can be controlled at any time in the main engine room, and it can also be remotely inspected, modified, and remotely Fault diagnosis and processing of high reliability unit design.

11. Low maintenance, fully automatic control, to ensure that the equipment is carried out under good working conditions and to give full play to the high performance of the equipment.

12. Quick response. The entire control system adopts closed-loop control, the temperature can be maintained in the set range, and fuzzy control is adopted to automatically adjust the speed of compressor startup and shutdown according to the actual situation, saving customers more time for production.

13. The PLC can display the basic information of the unit operation, as follows:

a. Compressor suction and discharge pressure, temperature; oil temperature, oil pressure difference

b. The current and voltage of the main motor

c. Compressor loading and unloading percentage

d. External start/stop command status; compressor starter status

e. Basic automatic protection function of the unit

f. Overcurrent

g. Compressor starter failure, compressor running failure, general failure, sensor failure.
