Abstract: A method, system, and control system for operating a HVAC system having one or more variable-speed components is provided. The method includes running the one or more variable-speed components at a first setpoint, and determining that the first setpoint generates a response having an intensity above a threshold. The response includes a vibration, a noise, or a combination thereof. The method further includes logging the first setpoint into a list of setpoints to avoid. The method also includes, in response to determining that the first setpoint generates the response having the intensity above the threshold, adjusting the one or more variable-speed components to a second setpoint.

Abstract: A sound attenuating enclosure with sound absorbing panels. The panels are positioned in an array of four side panels and a top panel. The array of panels is covered with vinyl material forming seams between adjoining panels and flaps for securing the panels together to form the enclosure. Each of the panels is provided with a pouch having a resealable opening for containing a flat sound reflecting element. One predetermined side panel is provided with apertures for allowing supply lines to pass through the enclosure.

Abstract: An elastomeric mount for a compressor is formed of upper and lower stud portions with a solid elastomeric section therebetween to thereby provide improved vibrational damping performance in both the vertical and transverse directions. The three elements are integrally joined by molding the studs into the elastomeric portion, and the binding between the elements is enhanced by way of an adhesive.
