## Abstract

The present disclosure is directed to a sunshade system that monitors a position of the sun and adjusts a position of a frame and/or blades based on a position of the sun. For example, a heating, ventilation, and air conditioning (HVAC) unit of an HVAC system may be exposed to adverse, external weather conditions, such as sunlight, which may heat up components of the HVAC unit and decrease an efficiency of the HVAC system. Accordingly, a control system of the sunshade system may monitor the position of the sun and adjust the position of the frame and/or the blades to provide adequate shading for the HVAC unit.

## Claims

### Claim 1

A sunshade system of a heating, ventilation, and/or air conditioning (HVAC) system, comprising:
a frame configured to move in at least one degree of freedom relative to an HVAC component of the HVAC system;
a plurality of blades coupled to the frame, wherein each blade of the plurality of blades is configured to rotate relative to the frame;
a motor configured to adjust a position of the frame or rotate the plurality of blades relative to the frame;
a sensor configured to monitor a solar position and generate solar position data based on the monitored solar position; and
a controller communicatively coupled to the motor, wherein the controller is configured to:
receive the solar position data from the sensor; and
instruct the motor to adjust the position of the frame or rotate the plurality of blades based on the solar position data and a relative position of the HVAC component to either shield the HVAC component from solar rays or to expose the HVAC component to solar rays, based on an operating condition of the HVAC component.

### Claim 2 (depends on 1)

The sunshade system of claim 1, comprising a linkage coupled to the motor and coupled to each blade of the plurality of blades, wherein the motor is configured to move the linkage to rotate the plurality of blades.

### Claim 3 (depends on 1)

The sunshade system of claim 1, wherein the motor is configured to rotate the frame in at least a ninety degree range.

### Claim 4 (depends on 1)

The sunshade system of claim 1, wherein the sensor comprises one or more sensors configured to generate the solar position data based on the solar position relative to an orientation of the frame, an orientation of the plurality of blades, or both.

### Claim 5 (depends on 1)

The sunshade system of claim 1, wherein the motor is configured to rotate each blade of the plurality of blades in at least a ninety degree range.

### Claim 6 (depends on 1)

The sunshade system of claim 1, wherein the sensor includes a Global Positioning System (GPS) device.

### Claim 7 (depends on 1)

The sunshade system of claim 1, wherein the controller is configured to:
receive a user input indicative of an instruction to move the frame to a second position; and
instruct the motor to move the frame to the second position based on the user input.

### Claim 8 (depends on 1)

The sunshade system of claim 1, comprising a second motor configured to rotate the plurality of blades relative to the frame.

### Claim 9 (depends on 8)

The sunshade system of claim 8, wherein the controller is configured to instruct the second motor to rotate the plurality of blades relative to the frame based on the solar position data.

### Claim 10 (depends on 1)

The sunshade system of claim 1, comprising a turntable configured to rotate the frame about a vertical axis.

### Claim 11 (depends on 1)

The sunshade system of claim 1, wherein the motor is configured to adjust the position of the frame and rotate the plurality of blades relative to the frame.

### Claim 12

A method of controlling positioning of a sunshade of a heating, ventilation, and/or air conditioning (HVAC) system, comprising:
monitoring, via one or more sensors, a solar position and a sunshade position;
generating, via a controller, solar position data based on the monitored solar position and sunshade position data based on the monitored sunshade position; and
instructing, via the controller, a motor to adjust a position of a frame of the sunshade based on the solar position data, a relative position of an HVAC component of the HVAC system, and the sunshade position data to either shield the HVAC component from solar rays or to expose the HVAC component to solar rays, based on an operating condition of the HVAC component, wherein a plurality of blades are coupled to the frame, each blade of the plurality of blades configured to rotate around an axis through a center of each blade of the plurality of blades relative to the frame.

### Claim 13 (depends on 12)

The method of claim 12, comprising instructing, via the controller, the motor to rotate the plurality of blades based on the solar position data and the relative position of the HVAC component of the HVAC system to shield the HVAC component from solar rays.

### Claim 14 (depends on 12)

The method of claim 12, wherein the solar position data comprises a solar position relative to an orientation of the frame.

### Claim 15 (depends on 12)

The method of claim 12, wherein the solar position data comprises a solar position relative to an orientation of the plurality of blades.

### Claim 16 (depends on 12)

The method of claim 12, wherein at least one sensor of the one or more sensors is a light intensity sensor.

### Claim 17 (depends on 16)
