Patent number: 12013161Abstract: An air conditioner unit and method of operating the same includes performing an operating cycle in a feedback control mode, including adjusting the an electronic expansion valve (EEV) to minimize an error between a measured superheat and a target superheat using a PI controller, determining that a target compressor speed has changed by greater than a predetermined speed threshold, and initiating a linear control mode of the operating cycle, including adjusting the EEV using a valve position equation that is a function of the target compressor speed, an indoor temperature, and an outdoor temperature. The controller may also start a transition timer upon initiation of the linear control mode, transition back into a feedback control mode upon expiration of the transition timer, and initialize the integral term of the PI controller based on the EEV position from the linear control mode.Type: GrantFiled: December 1, 2021Date of Patent: June 18, 2024Assignee: Haier US Appliance Solutions, Inc.Inventor: Joshua Duane Longenecker
