Abstract
A chiller for cooling a beverage includes a reservoir configured to hold a heat exchange fluid and an evaporator coil arranged within the reservoir. The evaporator coil includes a plurality of windings configured to circulate a coolant, and projections extending from an exterior surface of one or more of the plurality of windings. The chiller further includes a chiller coil arranged in the reservoir, wherein the beverage is configured to flow through the chiller coil. When the coolant is circulated through the plurality of windings of the evaporator coil, a bank of frozen heat exchange fluid forms on the windings and on the projections.
Claims16
A chiller for cooling a beverage, comprising:
- a reservoir configured to hold a heat exchange fluid;
- an evaporator coil arranged within the reservoir, the evaporator coil comprising:
- a plurality of windings configured to circulate a coolant, and
- projections extending from an exterior surface of one or more of the plurality of windings,
- wherein the projections each comprise a body defining a plurality of pores configured to permit the heat exchange fluid to flow through the plurality of pores to facilitate formation of a bank of frozen heat exchange fluid on the windings and on the projections when the coolant is circulated through the plurality of windings;
- and
- a chiller coil comprising windings arranged in the reservoir, wherein the beverage is configured to flow through the windings of the chiller coil,
- wherein the windings of the chiller coil have a shape that corresponds to a shape of the reservoir, and
- wherein the projections extend toward and are spaced from the chiller coil by a distance.
