The advanced Gas Driven VRF system offers increased efficiency and performance across the range.
Improvements include increased part load performance, reduced gas consumption with a Miller-cycle engine and reduced electrical consumption by using DC-Fan motors.
4 benefit points of ECO G Series
1. Limited electric supply.
Electric consumption of ECO G is only 9% compared to ECOi because gas engine is utilized for the compressor driving source.
2. High demand of DHW with heating and cooling cogeneration.
DHW is produced effectively thanks to heat from engine exhaust during heating and cooling.
3. Open and flexible design.
ECO G system is designed to connect various Indoor units and controllers which is available for ECOi system. With new GE3 series, Pump sown system has been also implemented to answer commercial needs.
4. Heating at low ambient temperature up to -20°C.
Stable heating capacity has been realized with waste heat recovery from the engine even if outside temperature is quite low.
1. Improvement in blast efficiency
New 3-blades fan.
Propeller shape with 3 blades is more efficient
Max. 30% of fan electrical consumption is saved compared to conventional fan.
2. Better partial load control
Reduce start / stop loss has reduced by expanding the are where continuous operation is possible. Annual operation efficiency has further improved by better efficiency at lower partial load.
3. New “L” type heat exchanger
Heat exchanger surface area is included by 25% compared to conventional model to optimize efficiency.
