Nobao Green Energy Saving GSHP Central Air Conditioning System Traditional Central Air Conditioning System Solution
Upfront Investment Invested by Nobao Group and saved tremendous upfront investment for customers Large upfront investment, the cost per square meter is 350-400RMB

Depreciation of Equipment

Undertaken by Nobao Group

Annual depreciation rate is 10%

Function Integrated system for heating,cooling,free hot water,floor heating and heating swimming pool services Need multiple different system to realize
Secondary Investment lifespan is 25 years and no need of secondary investment Same as the preliminary investment:350 RMB per m²
Operation Energy Consumption High efficiency, low energy consumption, saving 50%-70% energy compared with traditional system High energy consumption,low efficiency,oil-fired boiler.the cost for coal and gas is increasing
Maintenance Cost Nobao responsible for all the maintenance work within the energy management contracting period High maintenance cost
Maintenance Personnel 1-2 personnel 8-10 personnel
Daily Operation Maintenance Auto operation, free of maintenance VRV air-conditioning system:Refill the refrigerant every 6-7 years,risk of outside window maintenance,vulnerable external cleanliness,boiler system needs professional taking care of by turns,periodical maintenance and check,high safety risk.
Room Size Small room and low noise VRV air-conditioning system:unit placed outside the room,which affect the building beauty; water chilling unit and boiler room taking large areas
Environment Friendly and Policies No carbon dioxide emission,no noise and vibration; Green energy, improving your brand;Strong government policies support and cash subsidies High energy consumption,and emission,restricted by the regulations,boiler burning(coal,oil,gas, etc.) polluted environment.cooling tower creates noise and water molds pollution; High emission cannot sustain the development;Government penalty for polluting the environment and enforced reconstruction and check risk.

One Time Energy Utilization of Nobao GSHP Heating Mode (outlet water 65℃ at condenser, outlet water 5℃ at evaporator)

Items Power generation and output Combined heat and power generation Heat pump COP Utilization efficiency of the original fuel
