A refrigerator damper system employs a fluidic valve providing switching of air between refrigerated compartments without the need for a movable valve plate such as can be obstructed by ice. In one embodiment, a bidirectional fan provides switching from a first compartment to a second compartment and then from a second compartment to a first compartment with change of fan direction.

The invention relates to a cml (1) for storing at least one set (2) of products (20), particularly a set of products arranged on at least one storage support (3), said cell comprising ventilation means (4) for creating a rear-to-front air flow (A) circulating in the housing (14) from the rear to the front of the housing or for creating a front-to-rear air flow (B) circulating in the housing (14) from the front to the rear of the housing, and at least one first sealing device (5 or 6) comprising a first flexible sealing element (50 or 60) that is inflatable in relation to one of the walls (10, 11, 12) of the cell and towards the inside of the housing (14) under the effect of an air pressure which is generated in the housing (14) by said air flow (A or B). The first sealing device (5 or 6) comprises at least one second sealing element (52 or 62) that can be actuated between an inactive configuration and an active configuration in which it exerts a mechanical pressure on part of the first flexible sealing element (50 or 60), said mechanical pressure being oriented towards the inside of the housing (14) and allowing said first flexible sealing element (50 or 60) to be distanced from said wall (10, 11, 12) of the cell in relation to which said first flexible sealing element (50 or 60) is inflatable. The cell comprises actuating means that allow the second sealing element (52 or 62) to be actuated into its active configuration.

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 blast cell system is provided with simple and scalable designs that prevent short cycling of air flow through any pallets in blast cells. The blast cell includes a plurality of suction channels that provide independent fluid pathways for directing the air drawn from different rows in the blast cell into the fan.

A container for transport of biological samples, food or beverages under controlled temperature, or other perishable goods includes a housing compartment for the goods, which is delimited by one or more side walls and has at least one opening. At least one intermediate wall is provided inside the housing compartment and is adapted to divide the housing compartment into at least two sections. The intermediate wall has at least one vent pipe element that includes an upper opening connected to a lower opening through a duct, such that the lower opening communicates with one section and the upper opening communicates with the other section of the housing compartment. The vent pipe element also includes a fan adapted to create a forced-air flow from the upper opening to the lower opening and vice versa, so that the forced-air flow provides constant temperatures for the goods during transport.

The invention is applicable to the technical field of heat sinks, and provides a heat dissipating device and a vending machine. The heat dissipating device comprises a fan, a fan motor and a heat dissipating cavity; the fan is connected with the fan motor, and the heat dissipating cavity comprises a first end surface close to the fan and away from the fan. a second end surface; the first end surface and the second end surface further comprise a plurality of sets of heat dissipating copper tubes parallel to the first end surface and disposed in the same direction, and the heat dissipating copper tubes in each set of heat dissipating copper tubes are parallel to each other, and the same group of heat dissipating The copper tube is also covered with a wide gap metal mesh; wherein the fan motor is a positive and negative motor; when the vending machine refrigeration system is started, the fan motor is reversed within a preset time to drive the fan to reverse, so that the heat dissipation cavity is obtained. Wind power from the first end to the second end. The invention can clean the heat sink in time, so that the vending machine refrigeration system can operate stably and efficiently.

A blast cell system is provided with simple and scalable designs that prevent short cycling of air flow through any pallets in blast cells. The blast cell includes a plurality of suction channels that provide independent fluid pathways for directing the air drawn from different rows in the blast cell into the fan.

A refrigerator includes a storage chamber, an evaporator configured to cool the storage chamber, and an air passage through which cold air generated by the evaporator flows. The air passage includes a blower fan configured to blow the cold air to the storage chamber, and a trap part in which warm air generated by a defrosting operation stays, such that warm air generated by the defrosting operation is prevented from being introduced into the inner space of the refrigerator through the air passage. The refrigerator reduces the defrosting operation time, efficiently prevents increase of the inner temperature of the refrigerator due to warm air during the defrosting operation, reduces a temperature difference in inner temperature of the refrigerator, and prevents food stored in the refrigerator from being rotten due to a temperature change.

A system for blast-freezing items includes a plurality of cells arranged side-by-side, each cell including a housing with a bay space, a plenum, a front air passage, a rear air passage, and a fan. The fan is positioned in the plenum and configured to circulate air through the bay space. Each cell also includes a plurality of channels to separate pathways of air to segments of the bay space. The system also includes a plurality of crane rails extending between rows of cells and at least one crane capable of traveling along the plurality of crane rails to load or unload each of the plurality of cells.
