Abstract: A centrifugal blower includes a centrifugal fan having a fan wheel that is configured to rotate about a rotational axis. The centrifugal blower includes a blower housing having a first side panel, a second side panel, and a wall extending about the rotational axis and between the first and second side panels. The centrifugal blower also includes a cutoff plate that is configured to extend about the rotational axis, where the cutoff plate includes a first end with a flange having a camber geometry and a second end that is configured to overlap with the wall such that an amount of overlap between the second end and the wall is adjustable to adjust a position of the flange relative to the fan wheel. The centrifugal blower further includes an exhaust port defined by the first side panel, the second side panel, the wall, and the flange.

Abstract: The present disclosure describes techniques concerning a fan assembly. The fan assembly may include a fan, having multiple blades to rotate about an axis, and a housing in which the fan is disposed. Additionally, the fan assembly may include an air inlet formed in a wall of the housing that is transverse to the axis. The air inlet may define an orifice and includes multiple air guides that each extend into the housing from a perimeter of the air inlet.

Abstract: A heating system, includes a furnace that is configured to heat air to be provided to a conditioned space, a pressure sensor configured to collect sensor data indicative of a pressure of air within the furnace; a fan configured to supply the heated air to the conditioned space, and a motor configured to drive the fan. Additionally, the heating system includes processing circuitry communicatively coupled to the pressure sensor and the motor. The processing circuitry is configured to control the motor based upon the sensor data such that an amount of airflow supplied to the conditioned space is constantly supplied by the fan.

Abstract: An HVAC system includes, an electronic expansion valve (EEV), and a controller in communication with the EEV. The controller is configured to determine a minimum EEV setpoint position value based on a comparison of a superheat error value to a setpoint error threshold. The controller is further configured to determine a maximum EEV setpoint position value based on a comparison of a second superheat error value to a second setpoint error threshold. The controller is further configured to calculate an average setpoint value based on the maximum EEV setpoint position value and the minimum EEV setpoint position value. The controller is further configured to configure the EEV to a position corresponding to the average setpoint value and operate the EEV for a predetermined amount of time. The controller is further configured to operate the EEV according to a PID algorithm.

Abstract: A system for heating a building via refrigerant includes a coil temperature sensor, an ambient temperature sensor, and a controller. The controller includes a processing circuit configured to record a system operating parameter and a control step of a control process before performing a sacrificial defrost cycle. The processing circuit is configured to cause the system to perform the sacrificial defrost cycle and operate the system at predefined system operating parameters other than the recorded system operating parameters. The system is configured to cause the system to operate at the recorded system operating parameters and generate calibration data in response to the sacrificial defrost cycle ending. The processing circuit is configured to cause the control process to operate at the recorded control step and cause the system to perform a defrost cycle based on the calibration data, the coil temperature, and the ambient temperature.
