Автор: Brian S. Kim

Принадлежит: Individual

A defrost fan control device for a refrigerator is provided. The device comprises a container, a heat exchanger, a chamber, a suction pump, a condensate spraying device, an evaporation coil, and a blower. The suction pump is for sucking up the condensate from the container. The condensate spraying device is for spraying the condensate sucked up by the suction pump within the chamber. The evaporation coil is disposed around the condensate spraying device such that the condensate from the suction pump lands on an inner surface of the evaporation coil and evaporates the condensate. The blower is for inducing air flow within the chamber, whereby the evaporated condensate is exhausted from the chamber.

Принадлежит: Mitsubishi Electric US Inc

Systems and methods for low ambient air temperature cooling in air-source based heat pump systems wherein an outdoor heat pump unit includes a discharge hood positionable over its fan. The hood including a damper that is openable and closeable as a function of outside temperature. The outdoor unit may also include wind deflectors positioned over the coil openings of the disclosure. During cooling operations below a low outside air threshold temperature, e.g., below 23° F., the damper assembly partially closes to reduce airflow across the condenser coil of the outdoor unit to a level below that which is possible at minimum fan speed. As the outdoor temperature continues to drop, the damper assembly continues to close to further reduce airflow.

Passive vacuum relief valve for ultra-low temperature freezers

Номер: US20140034157A1

Автор: Yongrak Kwon

Принадлежит: Global Cooling Inc

A passive vacuum relief valve for an ultra-low temperature freezer. A thermally conductive tube extends through a freezer cabinet wall and opens into the interior cabinet space. The tube also extends outwardly from the cabinet wall in thermal exposure to ambient air so that it can receive heat from the ambient air. A valve enclosure has a chamber opening into the tube and is also positioned in the ambient air. A check valve, preferably a ball type, is formed in the valve enclosure and is polarized in a direction permitting ambient air to flow through the chamber and the tube into the freezer cabinet. The exposed tube is passively heated by the ambient air and provides a thermal conduction path to the valve and to the portion of the tube extending through the freezer cabinet wall to prevent moisture from freezing and locking the valve and/or obstructing the tube.

The heat exchanger is adapted for cooling a coolant (e.g., water), used to cool a device or an area (e.g., building interior), such as during periods of peak energy cost and usage, to save energy and energy costs. The heat exchanger includes a coolant storage tank with one or more refrigerant circulators in contact with the floor of the tank. The circulators use a refrigerant having a freezing temperature colder than the coolant, with coolant on the floor of the tank forming a layer of ice thereon. A rotary scraper extends up through the tank floor from each circulator, with the scrapers operating to remove the thin layer of ice from the floor as the ice forms. The resulting ice chips are relatively small and thin, thus having a relatively large surface area for their volume in order to maximize melting and rapid cooling of the coolant.

AIR-COOLED REFRIGERATOR, AND CONTROL METHOD, CONTROL SYSTEM AND CONTROLLER FOR DEFROSTING THEREOF

An air-cooled refrigerator and a control method, a control system and controller for defrosting thereof are provided. The high-temperature air of the air-cooled refrigerator exchanges heat with the evaporator in the air duct and is sent into a refrigerating compartment through the operation of a fan; when the evaporator is gradually frosted, the heat-exchanged air suffers the resistance from the frosts on the evaporator during the flow and the fan slows down. Based on this principle, the fan speed can directly correspond to the frost accumulation mass of the evaporator. The actual frost accumulation mass of the evaporator can be directly determined by determining the fan speed. When the fans peed is decreased to a certain low speed, it means that there is much frost on the evaporator and the defrosting needs to be started timely. As a result, the problems of large energy consumption and poor fresh-keeping effect caused by the traditional control method of defrosting in advance or delayed defrosting can be solved, and the energy-saving and fresh-keeping effects of the air-cooled refrigerator can be improved. 1. A method , comprising:collecting a first fan speed of a fan of an evaporator of a refrigerator during a stable operation of the refrigerator;determining whether the first fan speed is less than or equal to a threshold speed; andperforming a defrosting operation on the evaporator in response to the first fan speed less than or equal to the threshold speed.2.
