System Benefits


Through closed Double-U undergroud pipeline system, Nobao Ground Source Heat Pump main machine module extracts and powers the liquid that exchanges the heat or cold with the underground geothermal energy to provide multi HVAC functions to the relevant buildings.
Nobao GSHP system is an integrated green and eco system with multiple functions such as heating,cooling and water heating etc.It fully utilizes the shallow geothermal energy stored in the ground to be able to reach an energy saving from 50% to 70%,making it the energy efficient,environmentally clean,and cost-effective HVAC system available today.
 
  VRV system Water cooled chiller units + boiler system Nobao GSHP system
Mode of Exchange Air exchange Exchange heat/cold with water, open circulation through cooling tower plus boiler system (coal; oil or gas) for heating supply. Exchange with ground source energy, eliminating releasing excess heat/cold into surrounding air with no city heat island effects
Environment Exchange with release excess heat/cold to surrounding air, easy to cause city heat island effects High energy consumption, high CO2 emission, noise pollution Zero CO2 emission, no heat island effects, low energy consumption, neat & clean system
System mode Air cooling, low efficiency Water cooling,open cycle,high water consumption, boiler at very low efficiency for heating. Closed cycling water cooling exchange with ground source energy, stable, very high efficiency, heat recovery.
Efficiency Attenuation High Attenuation, meaning the more extreme outside air temperature, the lower efficiency. Medium attenuation because of the dependence of the cooling water on the surrounding atmosphere Underground temperature sustainable and stable, consistent high efficiency with zero attenuation regardless of atmosphere conditions
Space required Main machine placed outdoor or on roof, noise/vibration pollution, negative impact on architecture outview Need large in-house mechanical space and special boiler room, outdoor (roof) cooling tower produce noise/vibration pollution and negative impact building outview Small space required(1/3), flexible multi-module installation, very low noise, no outdoor equipment, no impact on outview
Average lifetime 10 - 12 years Water cooled units 15 years,Boiler 10 years Single system >25 years
Energy Exchange air cooled exchanger easy to be polluted, requires regular professional cleaning cooling tower efficiency decrease over the timeline also significantly Outdoor underground closed pipeline system energy exchange, no maintenance needs, no attenuation, lifetime more than 50 years
Maintenance System unstable, difficult repair once mal functioning. Needs professional personnel to daily operate and maintain. stable system, no requirement for daily
Energy Saving High initial investment, high operation and energy costs Medium initial investment, high operation and energy High initial investment, very low operation and maintenance cost
Operation risk Difficult maintenance and safety issue main machine malfunction influence whole system, boiler burning has high risk and need annual government check on safety and fire risk Zero CO2 omission, If one module malfunction, no influence on overall system, zero pollution or safety issue
