the COP value of the pack controller is calculated every 15 seconds from the three enthalpies h1, h2 and h3.
The calculation of the Carnot COP value is calculated from the COP values of the last 2 minutes.
Requirements
The following sensors must be present on the refrigeration pack system for the calculation of the COP:
The LP and HP pressure transmitters
The suction gas temperature sensors of the refrigeration points for the measurement of the enthalpy h1
All cylinder head temperature sensors for the measurement of the enthalpy h2
The gas cooler outlet temperature sensor for the measurement of the enthalpy h3
Connection of the temperature sensors
Hot gas temperature sensor: terminals 25/26
Attention: double assignment!
Do not use if the refrigeration pack system has more than 8 compressors.
Gas cooler outlet temperature: Terminals 31/32
Suction gas temperature sensor: Terminals 33/34
Cylinder head temperature sensor connection to the corresponding Pt1000 inputs
5.17.2 COP Optimisation
Only for combined control where parameter
M.com.out.reg. = No
, see menu 3-2-1-1.
The efficiency of the system depends on the compressor speed. In order to prevent the system from running
continuously with unfavourable efficiency (FC compressor operates at excessive speed), the controller
activates a compressor and reduces the speed of the FC compressor in order to switch to a more energy-
efficient operating point after a delay time of 10 minutes.
5.18 Operating Data and Archiving
5.18.1 Operating Hours of Compressors and Fans
The operating hours of all compressors and fans are recorded every 30 seconds and stored in non-volatile
memory. The display (menu 6-1) is shown in hours. In the case of replacement of compressors or fans or the
controller, the operating hours can be adjusted (menu 6-1-1 and menu 6-1-2).
The actual values of the COP calculation are shown in menu 2-6.
