Integrated high efficiency blower apparatus for HVAC systems

An integrated heating, ventilation and air conditioning (HVAC) blower apparatus, comprising:

• a centrifugal blower wheel disposed within a housing;
• an electronically commutated motor (ECM) in operative communication with said centrifugal blower wheel, said ECM extending at least partially through a first inlet cone disposed in a first side of said housing;
• and
• said centrifugal blower wheel further comprising:
• a first blade support;
• a second blade support;
• and
• a plurality of S-shaped blades extending between and coupled to said first and said second blade supports, wherein each of said S-shaped blades has a trailing edge bent in a forward direction with respect to a defined direction of rotation of said wheel, and the blade supports extend beyond the trailing edge of the S-shaped blade.

A heating, ventilation and air conditioning (HVAC) system for heating/cooling a space, comprising:

• a system controller;
• at least one of a heating and a cooling source;
• an integrated blower apparatus in communication with said system controller;
• and
• an airflow path for circulating air through the space;
• said integrated blower apparatus further comprising:
• a centrifugal blower wheel disposed within a housing, said centrifugal blower wheel further including a first blade support, a second blade support offset from said first blade support by a distance along a central axis of rotation, and a plurality of S-shaped blades extending between and coupled to said first and said second blade supports, wherein each of said S-shaped blades has a trailing edge bent in a forward direction with respect to a defined direction of rotation of said wheel, and the blade supports extend beyond the trailing edge of the S-shaped blade;
• and
• an electronically commutated motor (ECM) in operative communication with said centrifugal blower wheel, said ECM extending at least partially through a first inlet cone disposed in a first side of said housing.

A system, comprising:

• a heating ventilation and air conditioning (HVAC) blower, comprising:
• a first blade support;
• a second blade support offset from the first blade support by a distance along a central axis of rotation;
• and
• a plurality of S-shaped blades extending between and coupled to the first and second blade supports, wherein each of the S-shaped blades has a trailing edge bent in a forward direction with respect to a defined direction of rotation, and the trailing edge is generally free from the first and second blade supports.
