Model RTHF 250 G - 780 G (750 to 2760 kW)

Introduction

The Trane XStream™ RTWF G and RTHF G series are designed for higher reliability and energy efficiency, catering to today's environmental needs. As part of the EcoWise™ portfolio, these chillers utilize R1234ze, a low Global Warming Potential (GWP) refrigerant, to minimize environmental impact. They offer enhanced efficiency in both cooling and heating, with a proven track record of over 99.5% reliability. The industrial-grade design is suitable for commercial and industrial applications, including office buildings, hospitals, schools, retail buildings, and industrial facilities.

Key advantages include:

Very low environmental impact with near-zero GWP R1234ze refrigerant.
High efficiencies in cooling and heating.
99.5% reliability rate.
Suitable for high condensing temperature and heat pump applications, delivering hot water up to 85°C (RTWF G).
Versatile adaptation to various application requirements.

XStream RTWF G and RTHF G are available in several versions and efficiency levels: Standard Efficiency (SE), High Efficiency (HE), High Seasonal Efficiency (HSE), and Extra High Efficiency (XE) for RTHF G. HSE versions feature Trane Adaptive Frequency Drive (AFD) for improved High Part Load Efficiencies (ESEER).

Features and Benefits

Trane Helical-Rotary Compressors

Trane helical-rotary compressors are renowned for their reliability, built to demanding standards. With thousands of hours of testing, including severe operating conditions, they offer a proven track record with over 400,000 units worldwide demonstrating a reliability rate greater than 99.5%. These compressors are resistant to liquid slugging and feature fewer moving parts (male and female rotor), direct-drive, low-speed operation for high efficiency and reliability, and are field-serviceable. The suction-gas-cooled motor ensures longer motor life, and a five-minute start-to-start and two-minute stop-to-start anti-recycle timer allows for precise water-loop temperature control.

Capacity Control and Load Matching

The patented unloading system with a variable unloading valve allows compressors to modulate infinitely, precisely matching building load and maintaining chilled-water supply temperatures within ±0.3°C. This contrasts with stepped capacity control systems that can only maintain temperatures within ±1°C and often lead to overcooling. The RTWF G and RTHF HSE G versions, equipped with the Adaptive Frequency Drive (AFD), achieve excellent efficiencies at both full and part load by precisely matching building load. HSE units are compliant with Class C3 industrial environment requirements of EN61800-3.

CHIL Evaporator

Trane developed a compact, high-performance, integrated design CHIL evaporator for XStream chillers. It optimizes refrigerant flow for excellent heat exchange with water under all operating conditions and minimizes refrigerant charge.

High Condensing Temperatures Applications

For heat pump or low leaving temperatures industrial process applications, compressors operate under severe pressure conditions. XStream RTWF G units feature a specialized compressor design to handle these conditions, allowing temperatures as low as -12°C on the evaporator side or as high as 85°C on the condensing side while maintaining high efficiency and reliability.

Variable Primary Flow (VPF)

VPF systems offer cost-saving benefits related to pumps, including the elimination of the secondary distribution pump and associated piping, labor, electrical service, and VFD costs. Trane's software analysis tool can help determine if VPF is justified by anticipated energy savings. The XStream series evaporators can withstand up to 50% water flow reduction, provided the flow remains above minimum requirements. The control algorithms manage flow changes to maintain precise leaving evaporator temperatures.

Factory Testing

All XStream chillers undergo a comprehensive factory functional test, including sensors, wiring, electrical components, microprocessor function, communication capability, and expansion valve performance. Each compressor is run-tested for capacity and efficiency verification. Units are factory preset to customer design conditions, ensuring a trouble-free start-up.

Factory-Installed and Tested Controls

All chiller options are factory installed and tested, ensuring proper function and reducing installation expenses for the customer.

Superior Control with UC 800™ Chiller Controls

The Adaptive Control™ microprocessor system enhances XStream chiller performance by providing advanced control technology. It minimizes unnecessary service calls and unit shutdowns by only shutting down the unit when operating limits are violated after all corrective actions have been exhausted.

SmartFlow Control

XStream series units are compatible with variable flow operation on both evaporator and condenser sides. The pump speed is modulated to maintain a constant chiller temperature difference (ΔT). Entering and leaving evaporator temperatures are measured by the chiller controller via a factory-supplied sensor, with a ΔT setpoint on the unit controller.

System Option: Ice Storage

The UC 800 optimization software manages equipment for ice storage systems. It can optimize chiller operation for ice production or ice consumption modes, balancing chiller and ice contributions to meet cooling loads. This extends chiller plant capacity and reduces cooling costs by utilizing stored ice during periods of high electrical demand.

Series Counterflow Chiller Configuration

For multiple chiller plants, a series piping configuration can offer greater efficiency by saving pumping energy through larger ΔT and low flow designs. This layout also improves efficiency for the upstream chiller. Combining series piping with Variable Primary Flow (VPF) further enhances system efficiency. Series piping can also be applied to the condenser side, creating a Series-Series counterflow configuration with similar benefits.

For more information on series chiller arrangements, refer to the Trane Application Engineering Manual about Multiple-Chiller system design and control (SYS-AP M001).

Product Certification

Trane participates in Eurovent and AHRI chiller certification programs, ensuring units comply with declared performance through third-party certifications.
