- Collaborate with global specialized lab in the design of key parts; utilize finite element calculation to optimize the design.
- The electrically controlled cabinet of the compressor is at low-temperature part of compressor. The electric unit has a long service life.
- The Carrier patented self-adapting control avoids the over-cycling of compressor, highly increasing the life span of the compressor.
- When the pressure of the condenser abnormally heightens, the compressor can automatically relieve pressure. When accident occurs (e.g. the fin coil of the condenser blockades; the fan malfunctions), the chiller can automatically regulate the cold quantity and continuously run reliably.
Strict Durability Test
- Salt spray corrosion resistance test;
- Over-time fatigue test for pipeline and fan support of compressor;
- Simulation transport test in reference to the military product test standard, with effect equivalent to 4000 km transport on the truck.
PRO-DIALOG PLUS control
The Pro-Dialog Plus microcomputer control system designed specifically for the optimization of the air cooling cold water chiller to combine perfectly the simple and quick operation and advanced and complex central air-condition control concept. The system monitors in real time the running parameters of the chiller, accurately manages the compressor, electronic expansion valve, fan and pump (with in-built hydraulic module option) to run in the best energy utilization rate.
- Inner clock module can control the activation/stop of the cold water chiller and the running of the setting point of the second work;
- Auto-regulate the running parameter setting according to the temperature of the external conditions or that of the backwater.
- The two chillers primarily or secondarily control, which can balance the running time of the two chillers, and realize auto-switch when one chiller is at fault.
- The graphic operation interface visually shows the main running parameter of the equipment: temperature, pressure, setting point, running time of the compressor, etc.
- The 10 menu buttons on the control panel allow direct management of the running of the chiller, the easy output of history record of the error, and the quick and comprehensive auto-diagnosis of the chille
Remote management (standard)
Pro-Dialog Plus provides RS485 standard serial telecommunication port. Its simple connection with Carrier CCN control network may realize advanced remote management, monitor and diagnosis: start/stop, dual work conditions setting, energy demand limit, user safety interlock, water pump control and running switch, heat recycling, running indication, error clue, error warning, etc.
- Energy management module (option) can also realize other remote managements of the chiller: room temperature control, work condition value regulation, energy demand limit, user safety interlock, close of timing procedure, stop, indication of cooling quantity, running status of compressor, etc.
