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.

A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a heating fluid circuit, a cooling fluid circuit, and a storage fluid circuit. A thermal system of the HVACR system absorbs energy from the storage fluid circuit and rejects it to the heating fluid circuit. The storage fluid circuit includes thermal storage tanks containing thermal storage material that can provide energy for heating or absorb energy for cooling depending on the state of the thermal storage material. Heating can be provided using the heating fluid circuit and the heat provided by the thermal system. Cooling can be provided using the cooling fluid circuit by absorbing energy from the conditioned space using a cooling fluid and rejecting energy from the cooling fluid to the storage fluid circuit including the thermal storage tanks. The thermal storage tanks can also have heat added to them using an air source heat pump system to provide sufficient storage for heating operations.

A refrigerator appliance may include a cabinet, a liner, a sealed system, a conductive ice mold, a thermoelectric heat exchanger, and a water dispenser. The liner may be attached to the cabinet and define an icebox (TB) compartment. The sealed system may include a compressor to motivate refrigerant through the sealed system, and an evaporator disposed along an air path in fluid communication with the compressor to exchange refrigerant therewith. The conductive ice mold may be mounted within the IB compartment. The conductive ice mold may define a mold cavity along the air path to receive a chilled airflow from the evaporator. The thermoelectric heat exchanger (TEHE) may be disposed on the conductive ice mold to draw heat therefrom. The water dispenser may be positioned below the ice mold to direct an ice-building spray of water to the mold cavity.

A method and system for transporting and/or storing temperature-sensitive materials. In one embodiment, the system may be a hybrid system that includes an active temperature-control system and a passive temperature-control system. The active temperature-control system may be, for example, a portable refrigerator that includes an internal chamber for maintaining contents within a desired temperature range. The passive temperature-control system, which includes at least one phase-change material (PCM) member and space for receiving one or more temperature-sensitive materials, may be removably positioned entirely within the internal chamber of the active temperature-control system. When temperature-sensitive materials are loaded into the passive temperature-control system and the passive temperature-control system is loaded into the active temperature-control system, the active temperature-control system keeps the temperature-sensitive materials within a desired temperature range and charges the PCM members for when the passive temperature-control system is thereafter removed from the active temperature-control system.
