1. INTRODUCTION
1.1 General features
Hecu CO2 is a control system for complete management of R744
condensing units fi tted with BLDC compressors. The serial connection
between the condensing unit and the evaporators controlled by
MPXPRO/UltraCella and CAREL EEV expansion valves represents one of
the main features of this solution, contributing to the energy effi
ciency
and reliability of the entire system. The control board is designed for
DIN rail assembly and is fi tted with plug-in screw terminals, as well
as incorporating a driver for managing two electronic expansion
valves. A user terminal (PGDe or pLDpro) is also available for service or
commissioning the system.
Main features:
•
Modulation of cooling capacity by BLDC compressor with inverter;
•
Management of a fi xed-speed backup compressor;
•
Management of two modulating fans;
•
Card with built-in driver for CAREL unipolar valves;
•
Management of unipolar high-pressure valve (HPV);
•
Management of unipolar fl ash gas valve (RPRV);
•
Serial communication with evaporators (max 5);
•
RS485 serial for BMS;
•
Floating suction pressure set point;
•
Floating condensing pressure set point;
•
Advanced algorithm for calibrated oil injection to the compressor;
•
Oil speed boost for oil return to the compressor;
•
Oil recovery washing for oil return to the compressor;
•
Vast confi guration of defrost functions;
•
Suction and discharge superheat control;
•
Ample confi guration of alarms.
