Abstract: An appliance includes a first compartment and a second compartment. A temperature of the first compartment is determined with a first temperature sensor, and a temperature of the second compartment is determined with a second temperature sensor. If the temperature of the first compartment is above a first predetermined value and the temperature of the second compartment is above a second predetermined value, a controller causes the appliance to enter a pulldown mode. Upon entering the pulldown mode, the controller causes a valve to enter a first position where refrigerant flows to a freezer evaporator and is prevented from flowing to a fresh food evaporator.

Abstract: A communication device for pipes of an air conditioner disclosed herein transmits and receives communication signals using induced electromagnetic force, generated by a signal line wound around a core assembly, thereby facilitating for coupling between the core assembly and the signal line. Also, one type of core assembly can be commonly applied to various standards of pipes. Rainwater or foreign materials cannot permeate between the signal line and the core assembly by winding the signal line on the core assembly, despite of external installation, thus preventing breakdown or degraded communication performance of the communication device. Also, with forming a signal line mounting hole through the core assembly, the signal line is fixedly inserted through the signal line mounting hole, thereby preventing in advance a movement of the core assembly even though a refrigerant pipe vibrates.

Abstract: Hot air containing water is discharged from a heating space to pass through a vertically bent fluid pipeline (1035) formed by an hot air section (1030) of a water condensing pipeline structure (1029) and a vertically bent flow guiding structure (1032). Meanwhile, external inlet air having relatively low temperature is pumped through an cold air section (1031) of the water condensing pipeline structure (1029) to enable the hot air to be cooled, thereby condensing the water contained in the hot air. The condensed water is collected or flows with a first part of the hot air to pass through an hot air shunt port (1026) for being guided to an external discharging port (109). A second part of the hot air is guided by the hot air shunt port (1026) to flow towards a hot air return inlet (1022), thereby reducing the thermal energy loss and saving electric energy.

The ice containment device further offers the capability of holding a desired level of retraction to the ice within the cooler. The provision for retraction of the ice and thereby the ability to adjust both the proximity of the ice to the items in the cooler as well as the weight of the ice upon those items can be utilized to cool fragile objects.
