Blower assembly for HVAC system

A blower assembly for a heating, ventilation, and air conditioning (HVAC) system, comprising:

• a fan wheel;
• a motor directly coupled to the fan wheel and configured to drive rotation of the fan wheel;
• and
• an enclosure comprising a first side panel, a second side panel, and a curved panel extending from the first side panel to the second side panel to define an internal volume of the enclosure, wherein the first side panel comprises an air inlet opening formed therein, the second side panel comprises a main panel and a cover panel configured to removably couple to the main panel, the main panel comprises an opening and a slot formed therein, the motor is configured to be disposed at least partially within the opening and to mount to the second side panel in an assembled configuration of the blower assembly, the cover panel is configured to occlude the slot in the assembled configuration, and the motor and the fan are removable from the enclosure via the slot, comprising a side rail attached to the second side panel, wherein the side rail comprises retention flange configured to linearly translate within a retention slot of a guide rail of the HVAC system during installation and removal of the blower assembly, and the retention flange is configured to be retained within the guide rail in an installed configuration of the blower assembly with the HVAC system.

A heating, ventilation, and air conditioning (HVAC) system, comprising:

• a housing defining an air flow path therethrough;
• a platform disposed within the housing, wherein the platform comprises a guide rail attached to a support surface of the platform;
• and
• a blower assembly configured to be disposed within the housing,
• wherein the blower assembly comprises an enclosure, a fan wheel disposed within the enclosure, and a motor directly coupled to the fan wheel and mounted to the enclosure,
• wherein the enclosure comprises a curved panel, a first side panel attached to the curved panel, a second side panel attached to the curved panel, and a side rail attached to the second side panel, and the side rail comprises a retention flange, and
• wherein the blower assembly is configured to translate in a linear direction and along the platform from an uninstalled configuration to an installed configuration within the housing and atop the support surface of the platform, the retention flange is configured to translate within and along a retention slot of the guide rail, in the linear direction, during transition of the blower assembly from the uninstalled configuration to the installed configuration, and the guide rail is configured to engage with the retention flange to restrict movement of the enclosure of the blower assembly within the housing in the installed configuration.
