Abstract
Abstract An apparatus for reducing the amount of ice buildup on a discharge grill of a heat pump outdoor unit includes an ice ring surrounding a central part of the grill for preventing the formation of ice thereon. The apparatus has a support member disposed within the ice ring and is positioned over a central disc of the grill for supporting an ice disc. The ice disc is mounted upon the support member for preventing the entrance of freezing rain, sleet or the like onto the central area of the grill so as to minimize the formation of ice.
