* HVAC: Heating, Ventilation and Air Conditioning
Market NeedsHVAC System uses vast amount of energyAbout HALF of the electricity used in commercial buildings is used in HVAC system.
Energy-saving requirements of Government and
EnterprisesGovernment and large companies (such as hotels) need to meet annual energy-saving targets.
Difficulties in HVAC management
It is difficult for general technical or management personnel to fully understand wide varieties of complicated HVAC systems.
Requires a simple and effective intelligent energy-saving systemSaves energy without increasing human resources
