YMAA Air - Cooled Inverter Scroll Chillers And Heat Pumps
Range 12TR to 72TR
The YORK Amichi Series Air-Cooled DC Inverter Scroll Chillers and Heat Pumps have been designed to meet tomorrow's efficiency standards today. Delivering performance beyond typical chiller and heat pump efficiency levels, the YORK Amichi Series meets or exceeds stringent regulatory requirements through an optimized combination of efficiency-enhancing technologies from YORK".
Direct current (DC) inverter technology:
Provides variable capacity control and allows Amichi Series chiller compressors to operate more efficiently across all cooling load and ambient temperature conditions versus constant-speed chillers that use a step unloading design.
Electronically commutated (EC) fans:
Use more efficient motors and better aerodynamics to improve overall system efficiency and sound performance, particularly in part-load conditions. At reduced ambient temperatures, the head pressure control varies fan speeds to optimize the system efficiency and ensure reliable operation. This combination of variable speed compressor and fans provides a displacement power factor as high as 0.93, lowering electricity costs.
High-efficiency brazed plate heat exchanger:
Uses less refrigerant and transfers heat from the liquid to refrigerant more efficiently, providing excellent heat transfer performance in a compact design. This also results in a lower water side pressure drop, allowing the use of smaller pumps to further minimize building power consumption.
Tandem compressor design:
Uses several circuits, which improves off-design and part- load efficiency by using the entire surface area of the heat exchanger at all conditions while also providing partial redundancy.
