Abstract
An automated cooling system and method for energy efficient use with a building structure by adjusting operational parameters is provided. The automated cooling system can adjust operational parameters in response to conditions (e.g., temperature, humidity) detected by sensors located at one or more strategically selected locations inside or outside the building structure. The automated cooling system can ramp speeds of a motor that rotates fan blades in response to changes in the air temperature in the building structure so as to maintain a desired temperature without switching on and off the motor to preserve fan blade inertia.
Claims28
An automated cooling system for use with a building structure, the automated cooling system comprising:
- a housing comprising an inflow end and an outflow end;
- a motor configured to rotate a fan drive shaft;
- a fan blade assembly secured to the fan drive shaft so that rotation of the fan drive shaft causes the fan blade assembly to rotate;
- a bracket connected to the housing and the motor to position the motor within the housing, wherein the motor and the fan blade assembly are disposed within the housing and configured to draw air from an attic space of the building structure into the housing through the inflow end and to exhaust air out of the housing through the outflow end to exhaust air out of the attic space, wherein the housing is configured to be mounted to the building structure;
- a condition sensor comprising a temperature sensor;
- and
- a control unit configured to communicate with the condition sensor and configured to receive a condition sensor signal from the condition sensor, the control unit configured to communicate with the motor and configured to change a speed at which the motor rotates the fan drive shaft, wherein the control unit is configured to determine a target speed based on a value of the condition sensor signal using a lookup table,
- wherein the control unit is configured to determine an air temperature based on the condition sensor signal and compare the air temperature to a desired temperature, wherein the control unit is configured to maintain a temperature of the attic space at the desired temperature by sending a first motor signal for the motor to operate at a first speed based on the air temperature being higher than the desired temperature, and sending a second motor signal for the motor to operate at a second speed based on the air temperature being lower than the desired temperature, the second speed being less than the first speed, such that motor speed is automatically adjusted in response to changes in the air temperature in the attic space so as to maintain the temperature of the attic space at the desired temperature without switching on and off the motor to preserve fan blade inertia while maintaining the temperature of the attic space at the desired temperature.
