SANYO CO2 ECO is a system that effectively utilizes heat in the atmosphere
Environmentally friendly
A natural refrigerant (CO2) heat pump hot water supplier that considers the global environment.
For its refrigerant, SANYO "CO2 ECO" uses heat energy derived from compressed CO2, friendly to the ecosystem and our living environment. CO2 is an atoxic natural refrigerant with Ozone-Destruction Potential "0" and Global Warming Potential "1".
Economical
The high-efficiency heat pump method enables its superior energy-conservation capability
The coefficient of performance (CO2) is 3.75 for SANYO "CO2 ECO" compared to 1 for electric heaters (standard condition).
Low ambient operation
With SANYO "CO2 ECO", the heat pump operates continuously in the harsh condition of -20°C, maintaining its performance at no less than 4.0 kW. The consistent operation of the heat pump extremely low temperatures is made possible by the refrigerant circuit technology developed and refined by SANYO The heat pump operation of many models using "HCFC or HFC" as the refrigerant can only withstand the ambient temperature up to approximately -10°C. Electric heaters are required for temperatures below this level, resulting in performance that is not high in efficiency
The world First C02 ECO Rotary 2-stage Compression System
SANYO "CO2 ECO" adopts the rotary 2-stage compressor, a creation of SANYO original technology.
The outstanding performance of SANYO's "2-stage compressor" supports the basic operation capability of "CO2 ECO".
Resistant to high working pressure
Internal intermediate pressure system
- easier to design shell (lower D.P.)
Resistant to large pressure difference
2-stage compression system
- high-reliability through load dispersion
- high efficiency (lower leakage loss)
- low vibration and low noise
High efficiency and lightweight design
2-stage compression system - DC brushless motor and inverter drive
- high efficiency intensive winding motor with high-power neodymium magnet
Silent operation
With SANYO "CO2 ECO" the noise level during operation is 45 dB-A
