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.

The resent invention provides a refrigerator comprising: a cabinet having a storage chamber; a door for opening and closing the storage chamber; a case having a discharge port through which air is discharged to the storage chamber; an evaporator provided inside the case and for supplying cold air by means of heat exchange with air; a fan installed on the discharge port and for generating the airflow discharging to the storage chamber the air which has been heat exchanged in the evaporator; and a differential pressure sensor having a first pipe, of which one end is positioned on a part where the air is withdrawn to the fan, and a second pipe of which one end is positioned on a part where the air is discharged from the fan.

A refrigeration system for an interior space (260), includes an evaporator coil (230) and evaporator fan (242) residing within the interior space, the evaporator coil (230) being configured for refrigerating the interior space (260); an evaporator motor (235) coupled to the evaporator fan (242) along an axial shaft; a condenser coil (215) and fan (210) disposed adjacent to the evaporator motor (235); and an insulation panel (250, 255) that separates the evaporator motor (235) from the evaporator fan (242).

A refrigerator appliance having a temperature controlled drawer with improved temperature control is provided. A sealed system including a compressor, an evaporator, and an evaporator fan may be configured for cooling the fresh food chamber. A controller is configured to operate the evaporator fan when the compressor is off in order to increase the temperature of the temperature controlled drawer. Additionally, or alternatively, a secondary fan may be attached to the temperature controlled drawer and may be selectively operated by the controller to circulate air from the chilled chamber through the temperature controlled drawer. In this manner, the temperature of the temperature controlled drawer may be more precisely controlled regardless of whether the compressor is running.

A fan assembly including a housing, an impeller, a first damper member, a second damper member, and an actuation assembly. The housing defining a number of outlets and the impeller being configured to rotate about a rotational axis to direct air towards the number of outlets. The first damper member at least partially extending circumferentially about the impeller and the second damper member at least partially extend circumferentially about the impeller. The actuation assembly is configured to selectively rotate the first damper member and/or the second damper member to partially block, completely block or completely open the number of outlets.

A supercooling refrigerator (1000) including: a refrigerator body (100); a door (200) for opening and closing one side of the refrigerator body (100); an accommodating portion (400) provided inside the refrigerator body (100) and seated with an object (M) to be stored; a cooling duct (600) including a fan for taking in air in the refrigerator body (100) and discharging the air, and an evaporator (630) for cooling the air discharged from the fan; and a cool air supply duct (700) formed with a cool air discharge port (710) through which the air cooled through the cooling duct (600) is discharged into the refrigerator body (100), the fan being a cross flow fan (620) including a plurality of discs (622), and a plurality of blades (623) disposed between the discs (622) along outer circumferential surfaces of the discs (622).

An isothermal container for preserving and/or transporting perishable or heat-sensitive products, includes a cryogenic compartment for a mass of a cryogenic fluid, a product storage compartment for the products to be preserved or transported, at least one Seebeck module, and at least one fan positioned within the product compartment to create forced convention therein that is electrically powered by the Seebeck module, which generates a voltage from the difference in temperature between the mass of cryogen and the ambient air temperature of the product compartment.

A freezing refrigerator heats an entrance side pipe of evaporator, which is difficult to heat in the related art, with the condensation latent heat of refrigerant that builds up in a lower portion of evaporator in a liquid state while being vaporized with the heat of defrosting heater so as to warm the outlet pipe by a second thermal coupling part thermally coupling an inlet pipe and an outlet pipe of evaporator, whereby temperature variation of the entire evaporator in a defrosting operation can be suppressed, and the power consumption of defrosting heater can be reduced.

A fan assembly and a refrigerator including a fan assembly may prevent a backward flow of air and include an orientation of a spoke that is configured to be in parallel with a direction of a fan outlet flow. The fan assembly may include a fan including a hub and blades; a motor to rotate the hub; an outer housing or housing that accommodates the fan therein; a support frame or frame including an annular body or frame body provided in and coupled to the housing, a bracket centrally positioned in the frame body that fixes the motor, and spokes extending between and coupled to the frame body and the bracket; anti-vibration members arranged along and fixed to the frame body, wherein the anti-vibration members connect the frame body to the housing; and a protrusion protruding outward from and along an outer circumferential face of the frame body to prevent a backflow of air from the fan.

A refrigerator including a housing mounted at a rear surface of a door to define a storage space of food, a basket disposed inside the housing, a duct extending to the housing from one side of an evaporator to supply cold air generated by the evaporator into the storage space of the housing, and a fan assembly coupled to the duct to allow the cold air to be forcibly supplied.
