A method and system of determining and displaying energy savings from an HVAC system operating in an energy saving mode. The HVAC system is operated to maintain a comfort mode temperature during a learning period. The energy consumed by the HVAC system at multiple outside ambient conditions during the learning period is determined. The correlation between a specific ambient condition and energy consumed by the HVAC system is determined. The HVAC system is run to maintain an energy saving setpoint temperature. The energy consumed by the HVAC system is determined at an ambient condition while maintaining the energy saving setpoint temperature. The energy savings are calculated as a function of the difference between the energy that would have been consumed by the HVAC system at the ambient condition based on the determined correlation and the energy consumed by the HVAC system while maintaining the energy saving setpoint temperature at the ambient condition

Novel twisted blades with an air foil for use with air conditioner condensers and heat pumps that provide improved airflow efficiency to minimize operating power requirements having an overall diameter across the blades being approximately 19 inches, and approximately 27.6 inches. The blades (AC-A) can run at approximately 840 rpm to produce approximately 2200 cfm of air flow using approximately 110 Watts of power from an 8-pole motor. Using an OEM 6-pole ⅛ hp motor produced approximately 2800 cfm with approximately 144 Watts of power while running the blades at approximately 1100 rpm. Power savings were 25% (50 W) over the conventional configuration. A second version of the fan (AC-B) with some refinements to the flow geometry produced a similar air flow while using only 131 W of power at 1100 rpm. Power savings were 32% (62 W) over the conventional configuration. Embodiments can include two, three, four and five blades equally spaced apart from one another about hubs. Additionally, a novel noise reduction configuration can include asymmetrically mounted blades such as five blades asymmetrically mounted about the hub. Short, conical diffusers were shown to further improve air moving performance by up to 18% at no increase in power. Embodiments coupled with electronically commutated motors (ECMs) showed additional reductions to condenser fan power of approximately 20%.

When there is no occupant in seats other than a driver seat during a foot mode, an air-conditioning controller executes a single seat concentration mode to prevent blowing of warm air to a passenger seat and a backseat by closing foot outlets on a passenger seat side and a backseat side. In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature. Thus, an electric power consumed by an electric motor of a blower can be reduced, thereby realizing energy saving.
