Abstract: Architectures and techniques are presented that can facilitate improved design and function of certain heating, ventilation, and air conditioning (HVAC) devices. Architectures directed to an improved evase device can be designed with rounded corners that can facilitate, e.g., mitigation of reverse flow that traditionally grows back from corners of a transition from an axial fan to a rectangular duct. Architectures directed to an improved intake device can be designed to limit intake from certain flow directions and to smoothly change flow direction, which can facilitate, e.g., reduction in noise. Architectures directed to an improved fan intake device can be designed to reduce noise without significantly reducing total pressure. Architectures directed to an improved air handler device can be designed to concurrently heat and cool air and to reduce dimensions (e.g., size, weight) that can reduce costs and mitigate shipping and installation difficulties.
