Eco-cute Heating System
For years, the Japanese have used CO2 as a "natural" refrigerant to provide abundant Hot Water for domestic or commercial use. . The use of CO2 as a refrigerant enables supply of hot water to the tank up to 65°C. This is a "complete boiler replacement product"
- Abundantly supply for space heating and tap water
- Environmentally friendly with CO2 natural refrigerant
- Continuous output down to -20°C (heat pumps using conventional refrigerants lose performance at low temperatures)
- High efficiency C.O.P.s up to 3.8
- Low noise and vibration
- 65° temp ensures natural pasteurisation to prevent legionella, without the need for electric heating.
SANYO CO2 ECO is a system that effectively utilizes heat in the atmosphere
The CO2 is recovered from industrial processes and sealed within the external heat pump at high pressure, producing hot water which is fed to an internal tank - either a matched Sanyo 223 litre tank or to an alternative thermal store - the bigger the better!
A refrigeration pipework installation is not required.
A 9kW Heat Pump connected to a Sanyo 223l tank will cope with up to 240sqm of floor space, a 4-bed house insulated to modern standards, with a peak heat loss of 15kW.
For larger areas or commercial applications, Heat Pumps are grouped together to serve larger tanks.
Systems can be designed to cope with varying demands for Heating water or DHW (e.g. washing)
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
Quiet operation
With SANYO "CO2 ECO" the noise level during operation is 45 dB-A
