Air Conditioner Squirrel Cage Blower
The amount of conditioned air needed to satisfy the load demand is calculated for maximum air flow. Because more air flow is generally needed for cooling applications the fan, blower, and duct work are sized to allow the proper amount of flow. Other factors in sizing the HVAC blower motor are the amount of changes of air per hour as required by the mechanical code. This can add additional load to the system as outside air being added to the system is often less than ideal for use in the HVAC system and will require additional conditioning.
Air Conditioner Squirrel Cage Blower - AC & heating blowers move the air throughout the system. The blower motor is sized to handle the load of air. Horsepower ratings are used to size the blower motors and range from fractional horsepower ratings into the hundreds depending on how big the load is. Proper air conditioning & heating preventive maintenance should be performed on the HVAC blower to maintain a good working order of the blower system. Large HVAC blower systems such as the one pictured needs to have the bearings greased and the belt changed on a regular basis.
