User Manual for Carrier 19XR/XRV Centrifugal Liquid Chiller

Key Information and Overview

The Carrier 19XR/XRV is a high-efficiency, single-stage centrifugal liquid chiller designed for large-capacity water cooling applications. It features a hermetic compressor with aerodynamic impellers and tunnel diffusers. The unit is designed for stability, low noise, and modular construction, with a nominal cooling capacity ranging from 1000 to 3000 kW.

SmartVu™ Control System

The chiller is equipped with the Carrier® SmartVu™ control system, which provides comprehensive monitoring and control capabilities.

• Interface: Features a 10-inch color touchscreen that supports up to ten languages and displays real-time operating parameters.
• Intelligent Operation: Includes pre-start checks (oil temperature, condensation pressure, bearing temperature, etc.) and dynamic regulation algorithms to optimize efficiency.
• Diagnostics: The system includes fault diagnostics with alarm codes. It can perform pre-diagnostics for maintenance (e.g., oil and filter replacement alerts) and send automatic email notifications in case of alarms if connected to the internet.
• Connectivity: Supports BACnet or Modbus protocols for easy integration into building automation systems or i-Vu™/WebCTRL™ networks.

Carrier ABOUND Connectivity

The system supports the Carrier ABOUND platform, which utilizes cellular communication to transmit real-time operating data to the cloud.

• IoT Integration: Provides continuous monitoring of equipment health and performance.
• Remote Diagnostics: Allows service technicians to access real-time data and maintenance history remotely, facilitating faster troubleshooting and repair.
• Analytics: Compares current performance against design specifications to provide actionable insights and preventive service solutions.

Options and Accessories

Various options are available to customize the chiller for specific applications:

• Variable Frequency Drives (VFD): Standard and high-efficiency options available.
• Motors: High-voltage motors (3000V to 11kV, 50Hz or 60Hz).
• Installation Aids: Anti-vibration springs, factory-installed starters, and delivery in multiple sections.
• Specialized Modules: Refrigerant leak detection sensors and hot gas bypass for low-load operation.
• Customization: Available for marine, oil and gas, and chemical industry applications.

Physical Specifications

The chillers are available in different chassis sizes (3, 4, and 5). Dimensions and weights vary based on the configuration. Users should refer to the physical characteristics table in the manual for precise length, width, height, and weight data (net and in-service) before installation.
