A novel method of deicing utilizing a fins-on-tubes type evaporator/heat exchanger system that is optimized for energy-saving inductive heating thereof, by configuring it to increase its resistance to a value at which the system's reactance at its working frequency is comparable to its electrical resistance. The system includes a set of tubes configured for flow of cooling material therethrough, and also includes a set of fins positioned and disposed perpendicular to, and along, the tubes, in such a way that at least a portion of the fins comprises longitudinal excisions therein.

An aircraft galley chiller is adapted to fit within a service column of the aircraft. The condenser is elongated, oriented vertically, and includes a bank of fans to increase airflow. The evaporator is also elongated and includes a bank of fans. The evaporator and condenser are oriented with the same plane to produce a footprint that fits within the service column. The evaporator includes a heater element to periodically heat and de-ice the evaporator.

A refrigerating unit including a compartment, a glass door, and a heating arrangement installed in a base profile of the compartment. The refrigerating unit including an elongated gasket profile having a proximal part and a distal part, wherein the proximal part includes a flexible element configured to allow the distal part to be displaced towards the base profile upon closing the glass door. The distal part includes a hollow part with a first side of the hollow part connected to the proximal part and a second side of the hollow part directed towards the glass door. The heating arrangement further includes a heat-conducting material enclosed by the hollow part and arranged with an outer side surface of the heat-conducting material abutting the second side of the hollow part, and a heating element enclosed by the hollow part and arranged for conductive heating of the heat-conducting material.

A refrigerator includes a cabinet, in which a cooling chamber and at least one storage space are defined, the cooling chamber being arranged at the bottom of the cabinet and directly below the storage space; a door body, which is arranged on a front surface of the cabinet so as to operably open and close the storage space; an evaporator, which is wholly horizontally placed in the cooling chamber in the shape of a flat cube, and is configured to provide cooling capacity to the storage space; and a liquid storage bag, which is arranged in the cooling chamber and connected to the evaporator. An included angle between a center line of the liquid storage bag and a horizontal line is 1° to 89°. A foam layer and a housing of the refrigerator may block the sound transmission of flow of a liquid refrigerant, to achieve a good sound insulation effect.
