  • Publication number: 20210368653
    Abstract: A heat transfer medium is used for a heat transfer system including a refrigerant cycle device through which a refrigerant circulates and a heat transfer medium circuit having an electric device. The medium includes an anhydrous liquid that does not contain water and is made of a substance having a polarity less than water. The anhydrous liquid is cooled by heat exchange with the refrigerant and absorbs heat from the electric device while circulating through the heat transfer medium circuit. Accordingly, the low viscosity of the heat transfer medium at a low temperature can be secured. Further, by using an anhydrous liquid without water as the heat transfer medium, it is possible to suppress an increase in an electrical conductivity of the heat transfer medium over time.

  • Publication number: 20210367291
    Abstract: A heat transfer medium is used for a heat transfer system including a refrigerant cycle device through which a refrigerant circulates and a heat transfer medium circuit having a cooling target device. The heat transfer medium is cooled through heat exchange with the refrigerant and absorbs heat from the cooling target device while circulating through the heat transfer medium circuit. The heat transfer medium includes a carboxylate aqueous solution formed by dissolving carboxylate in water. Accordingly, by using the carboxylate aqueous solution as the heat transfer medium, a low viscosity at a low temperature can be secured. Further, since the carboxylate aqueous solution has a high heat exchange efficiency, the cooling capacity of the heat transfer medium can be improved.

  • Patent number: 11003124
    Abstract: An image forming apparatus including an image forming unit, a fixing device, and circuitry is provided. The image forming unit is configured to perform a special image forming operation that forms a color toner image and a special toner image with a color toner and a special toner, respectively, on a recording medium and a normal image forming operation that forms the color toner image without forming the special toner image on the recording medium. The fixing device is configured to fix the color toner image and the special toner image on the recording medium. The circuitry is configured to perform, in the special image forming operation, a toner amount suppression control that makes an amount of the color toner on the recording medium per unit area smaller than that in the normal image forming operation.
