A refrigeration appliance with multiple storage compartments has a refrigerant circuit with a first expansion valve, a first heat exchanger, a second expansion valve, and a second heat exchanger connected in series between pressure and suction connections of a compressor. Each heat exchanger is associated with at least one storage compartment in order to control its temperature. A control unit controls the compressor rotational speed and positions of the expansion valves. The control unit has a continuously linear regulator for each storage compartment with a P-component for estimating a required temperature control output using a difference between actual and target temperatures. A model computing unit ascertains a target evaporation temperature for a first storage compartment controlled by the first heat exchanger, and for a second storage compartment controlled by the second heat exchanger. The heat exchangers are operated by selecting the compressor rotational speed and the valve positions of the expansion valves.

The present invention relates to a drawer assembly and a refrigerating and freezing device with the drawer assembly. The drawer assembly comprises a cartridge defined a drawing space and a modified atmosphere film assembly, an accommodating cavity is defined in a top wall of the cartridge, the accommodating cavity is communicated with the drawer space; the modified atmosphere film assembly is mounted in the accommodating cavity, and the modified atmosphere film assembly is provided with a modified atmosphere film and an oxygen-enriched gas collecting cavity, so that when the pressure of the oxygen-enriched gas collecting cavity is less than the pressure of the accommodating cavity, oxygen in air of the accommodating cavity penetrates the modified atmosphere film to the oxygen-enriched gas collecting cavity, so as to obtain a gas atmosphere with rich nitrogen and lean oxygen, facilitating for fresh keeping of foods.

A helmet cooling system includes a reservoir for holding a chilled medium and includes fan that that draws ambient air into the reservoir so that the air will pass over the chilled medium and exit the reservoir through a tube that is connected to a helmet. The helmet includes several channels for distributing the chilled air to the wearer's head to help keep the wearer comfortable. The reservoir can include a diverter valve to preserve the chilled medium when it is not necessary by sealing off the chilled medium and preventing air from circulating past it or otherwise contacting the chilled medium.

A refrigerator includes: a cabinet including a freezing chamber; an evaporator located at one side of the freezing chamber; a freezing chamber fan configured to supply cool air to the freezing chamber; an ice maker located in the freezing chamber and configured to perform ice-making; an ice bin located below the ice maker and separates and stores ice made in the ice maker; an ice detection device which detects whether or not the ice stored in the ice bin is full; and a control unit configured to control the freezing chamber fan according to a detection signal of the ice detection device. The control unit is configured to turn off the freezing chamber fan when ice-fullness is detected by the ice detection device and turn on the freezing chamber fan when the ice-fullness is not detected by the ice detection device.

A under counter refrigerator includes a main body defining at least one of a first and second storage compartments, an evaporator to generate cool air to be supplied to the at least one of the first and second storage compartments, and a machine room provided at a lower portion of the main body to define an installation space in which a compressor and a condenser are provided. The machine room includes a suction portion provided in front of the main body to suction outside air into the machine room, a discharge portion provided in front of the main body to discharge the suctioned air in the machine room, a guide wall to separate the installation space into a first space in which the condenser is installed, and a second space in which the compressor is installed. A condensation fan is installed at the guide wall, the condenser is provided in a front portion of the first space, a defrosting water tray is provided at a rear of the condenser, and the condensation fan is disposed on one side of the defrost water tray.

A refrigerator comprising a refrigerator body provided with a refrigerating compartment, an ice maker, an ice-making air duct, a first fan assembly disposed in the ice-making air duct and an ice maker evaporator is disclosed. The ice-making air duct comprises an air inlet duct and an air return duct, which are both disposed in a foaming layer of the refrigerating compartment, and one ends thereof close to the ice maker extend into a foaming layer on a door body of the ice maker. The first fan assembly is detachably disposed in the air return duct, and may be integrally disassembled from and installed in the air return duct. The ice maker evaporator is disposed between the air inlet duct and the air return duct and at the side far away from the ice maker.

Disclosed is a refrigeration unit having an accumulator, a refrigeration system and a method for controlling a refrigeration unit having an accumulator, wherein the refrigeration unit has a refrigeration chamber for receiving and storing goods to be refrigerated, an accumulator having an accumulator holder in which a storage medium is accommodated, a heat exchanger, a controller and a coolant line arrangement which can be connected to a coolant supply network via connections. The coolant line arrangement is guided through the accumulator holder, and the heat exchanger is thermally coupled to the storage medium accommodated in the accumulator holder.
