YHAU-CG-CA-CXR Double Effect Direct Fired Chiller/Heaters: The Flexible Solution for Everyday Applications
YORK YHAU-CG-CA-CXR Double-effect, Direct-fired Absorption Chillers/Heaters are driven by waste heat and low-cost heat to deliver highly efficient performance in a space-efficient design. The modular configuration allows multiple units to be arranged in a variety of footprints to fit different space requirements. And for easy building management system (BMS) integration, this unit comes with controls based on programmable logic controller (PLC) and industry-standard MODBUS connectivity.
Benefits
- Flexible Design: Featuring a compact footprint and modular design, this unit is an ideal solution for high-performance cooling and heating in tight spaces.
- Optimal Efficiency: This unit has a coefficient of performance of 1.23 with a turndown ratio from 100% to 25% at different temperatures.
- Trusted Reliability: World-class engineering and proven controls for easy BMS integration simplify operation and reduce unplanned maintenance downtime.
Features
- Low noise level of 80 dbA.
- Coefficient of performance (COP) of 1.23 based on lower heating value (LHV) with a turndown ratio from 100% to 25%.
- Controls based on PLC and industry-standard MODBUS connectivity for easy BMS integration.
- The space-efficient design of the unit simplifies installation through forklift loading or via an emergency/service elevator.
- Ambient temperature range of 5°C/41°F to 40°C/104°F with 10-90% relative humidity.
- Modular configuration allows multiple units to be arranged in a variety of footprints to fit different space requirements.
- Completely packaged and insulated from the factory with an easy-access enclosure, making the unit suitable for outdoor installations.
Higher System Efficiency
If saving energy and reducing emissions are the goals of an organization, the YORK YHAU-CG-CA-CXR is an ideal choice. This unit uses best-in-class burner combustion technology matched to a high-temperature generator furnace design that enhances system efficiency. It’s a perfect match for comfort cooling applications with low noise levels. The unit has a COP of 1.23 (LHV basis) with a turndown ratio from 100% to 25% at different entering condenser water temperatures.

Modular Configuration
The modular configuration of the YHAU-CG/CA-CXR allows multiple units to be arranged in a variety of footprints to fit different space requirements. This unique design feature also means it’s possible to incrementally increase capacity as buildings are constructed or spaces become occupied.
