Exceptional results

DC Inverter EVI Scroll Compressor

• New asymmetric wrap: Optimized design reduces leakages and invalid suction superheating.
• Non-contact seal design: Oil film seal formed by lubricating oil to reduce friction for higher efficiency and reliability.
• Relieve valve: More adaptive to variable pressure conditions to provide higher part-load efficiencies.
• Enhanced Vapor Injection (EVI) technology: Significantly extends compressor operation map and increases efficiency.
• DC inverter technology: Delivers stepless capacity control for precise capacity matching to meet building load variations and to reduce unit power input.

YORK Inverter Driver – the brains of the operation

The YORK Inverter Driver is engineered to meet the challenging performance demands of the YMAE chiller. The solution smartly manages inverter system operation to boost chiller efficiency. This ultimately results in serious energy savings for you, the customer.

BLDC Fan

The fan blades have been aerodynamically optimized for streamlined style that delivers extraordinarily low operation noise. This means minimal disturbances for the people in your spaces. The high-efficiency electronically commutated DC brushless BLDC motor regulates fan using a stepless speed method. The fan blades and motor align perfectly to deliver great low energy consumption.

Brazed Plate Heat Exchanger (BPHE)

A stainless steel high-efficiency BPHE ensures optimum heat transfer efficiency. This technology provides superior performance and longer life cycle. In addition, the cross and counter flow design supplies water to the refrigerant circuit for full heat transfer with each refrigerant system. This maximizes chiller efficiency, especially under part-load operation.

Real-time system efficiency optimization

Advanced control algorithms from YORK ensure your chiller system dynamically adapts to building load changes and tunes each individual unit to keep it running at its optimal efficiency. results in increased system efficiency by 14-20 percent compared to the normal fixed-speed modular system

Wide operating range

YMAE has a wide operating range for full-year operation:

Cooling: Operating ambient temperature from -15°C to 48°C for superior cooling performance.

Heating: Operating ambient temperature from -27°C to 43°C for stable heating performance that caters to different customer requirements.

Low inrush current

The inverter compressor has a low start-up current – in fact the maximum start-up current is smaller than the nominal current. This avoids shock to motors and drives from sudden current surges during start-up and enables a smaller transformer capacity and extended chiller lifetime.
