This document provides an overview of the Carrier 19XR/XRV single-stage centrifugal liquid chillers. It is intended for operators and maintenance personnel to understand the system's capabilities, control interface, and diagnostic features. The chiller is designed for high-capacity water cooling applications ranging from 1000 to 3000 kW.
Device Description
The 19XR/XRV series features a hermetic single-stage centrifugal compressor with aerodynamic impellers and tunnel diffusers. The system is optimized for non-chlorinated refrigerants (R-134a or R-513A) and utilizes high-efficiency evaporator and condenser tubes.
SmartVu Control System
The chiller is equipped with the Carrier SmartVu control system, featuring a 10-inch color touchscreen interface. Key capabilities include:
- Real-time monitoring of operating parameters.
- Intelligent pre-start checks (oil temperature, condensation pressure, bearing temperature, etc.).
- Dynamic regulation algorithms for efficient operation.
- Comprehensive protection against surges, overcurrent, and overheating.
- Password-protected settings to prevent unauthorized changes.
Intelligent Diagnostics
The system includes advanced diagnostic tools accessible via the touchscreen. It logs fault codes, provides maintenance alerts (e.g., oil and filter replacement), and can automatically send email notifications to maintenance personnel if connected to the internet.
Connectivity and Automation
The control panel supports BACnet and Modbus protocols for easy integration into building automation systems. Optional i-Vu Link modules allow for centralized management and remote access via web browsers or mobile devices.
Carrier ABOUND Platform
The system supports the Carrier ABOUND IoT platform, which provides continuous cloud-based monitoring, performance analytics, and remote diagnostic capabilities, allowing service technicians to arrive on-site with pre-notified information.
Physical Specifications
The chillers are available in various chassis sizes (3, 4, and 5). Dimensions range from approximately 4230mm to 4980mm in length, with operating weights varying between 7200kg and 12160kg depending on the configuration.
