Abstract
A component configuration for enhancing the serviceability of a dispenser includes a platform positionable on the housing of the dispenser. A refrigeration unit mounts at a center and rear portions of the platform. An electronic control is disposed within a housing that is mounted at a center portion of the platform adjacent to the refrigeration unit. The electronic control housing permits access to the electronic control from the front of the dispenser. An evaporator coil of the refrigeration unit includes concentric coil sections defined by an inner coil section, an intermediate coil section, and an outer coil section.
Claims2
An apparatus for forming a frozen cooling fluid bank, comprising:
- a cooling chamber including sides, a top, and a bottom forming a closed container for holding a cooling fluid;
- an evaporator coil disposed within the cooling chamber, comprising concentric coil section defined by an inner coil section, an intermediate coil section, and an outer coil section, wherein the concentric coil sections include spacing therebetween so that the outer coil section cools the cooling fluid in the outer portion of the cooling chamber, the inner coil section cools the cooling fluid in the inner portion of the cooling chamber, and the intermediate coil section cools the cooling fluid in the portion of the cooling chamber between the inner coil section and outer coil section, thereby decreasing the formation time of a frozen cooling fluid bank;
- and
- a cooling fluid circulating device that circulates unfrozen cooling fluid during peak periods of use to create melt channels between the frozen cooling fluid surrounding the inner coil section and the outer coil section, thereby maximizing surface area contact between unfrozen cooling fluid and the frozen cooling fluid.
