A portable cooler container is provided, with a payload chamber for one or more temperature sensitive or perishable goods. A cooling unit is disposed in the payload chamber. The cooling unit includes a vessel filled with a cooling material (e.g., dry ice) and closed with a lid. One or more variable apertures of the cooling unit are operable to controllably release a chilled gas (e.g., CO2 gas) generated by the cooling material into the payload chamber of the vessel to cool the payload.

A method of controlling a refrigerator that includes: operating a cool air supply means with a predetermined output; a controller determining the output of the cool air supply means based on a current temperature of a storage compartment sensed by a temperature sensor while the cool air supply means operates with the predetermined output; and the controller operating the cool air supply means with the determined output. The controller determines that the output of the cool air supply means is decreased or increased when an absolute value of a difference between a previous temperature and a current temperature of the storage compartment is equal to or greater than a first reference value, and wherein the output of the cool air supply means is decreased or increased again when the absolute value of the difference between a current temperature of the storage compartment sensed again after a predetermined time has elapses and the previous temperature of the storage compartment is equal to or greater than the first reference value.

The present invention relates to a refrigerator. A refrigerator according to the present invention may comprises a first tray assembly forming one part of ice-making cells, and a second tray assembly forming the other part of same. Following the start of ice making process, so that ice can be produced in the direction of ice-making cells formed by any one tray assembly, from among the first and second tray assemblies, to the ice-making cells formed by the other tray assembly, the other tray assembly comprises a first surface forming a part of the ice-making cells, and a second surface extending from the first surface and supported by at least one surface of the one assembly.

A method, which is for controlling a temperature of a refrigerating compartment, includes cooling the refrigerating compartment, cooling the freezing compartment, determining a temperature of the refrigerating compartment, and based on the temperature of the refrigerating compartment, controlling the refrigerating compartment to a constant temperature range by controlling opening and closing of first and second passages of a three-way valve of the refrigerator to alternate cooling the refrigerating compartment and cooling the freezing compartment.

An ECM motor, including: a motor controller and a motor body. A microprocessor of the motor controller is connected to a first temperature detecting unit and a second temperature detecting unit disposed at different positions outside the ECM motor for detecting temperatures at the different positions. In operation, when the temperature difference between the first temperature T1 and the second temperature T2 is smaller than or equal to a preset value T0, a first gear at the rotational speed S1 is selected by the microprocessor and the motor is controlled to run constantly in the first gear at the rotational speed S1. When the temperature difference between the first temperature T1 and the second temperature T2 is larger than the preset value T0, a second rotational speed S2 is selected by the microprocessor and the motor is controlled to run constantly in the second gear at the rotational speed S2.

A refrigerator including a refrigerator compartment; a freezer compartment; an ice compartment disposed in the refrigerator compartment; an ice maker assembly disposed in the ice compartment, the ice maker assembly including an ice maker tray/evaporator having an evaporator cooling tube which is in direct contact with the ice maker tray portion; an ice bucket for storing ice disposed in the ice compartment; and an air handler/auger motor assembly disposed at a rear portion of the ice compartment behind the ice bucket. The air handler/auger motor assembly includes an air passage having a fan disposed therein. An inlet of the fan communicates with an airflow passage under the ice maker tray/evaporator, such that the fan creates a suction and draws cool air from the ice maker tray/evaporator and discharges the cool air through the air passage and to the ice bucket to prevent any ice in the ice bucket from melting.
