Claims

[Claims for Utility Model Registration] (1) A dry air supply device for preventing moisture condensation on tools that are heated during operation and cooled by a refrigerant, comprising: a movable housing; a pre-cooling/pre-dryer provided within the housing and receiving ambient air through the housing; an absorption dryer provided within the housing; and a pre-cooling/pre-drying device provided between the absorption dryer and the pre-cooling/pre-drying device. a first conveying means, a fan provided in the first conveying means, a common mixing chamber for mixing dry air, and a fan provided between the absorption dryer and the common mixing chamber. a second conveying means; an adjustable bypass duct leading from the first conveying means to a common mixing chamber; a blower box having a wide area injection nozzle for blowing dry air onto the tool; a dry air duct extending from the mixing chamber to the blower box; a control device for regulating, respectively, the flow rate of the dry air through the bypass duct, the temperature of the refrigerant and the operation of the tool; and as close as possible to the tool surface. a measuring device located at a location where the dry air is blown onto the tool and measures the relative humidity and temperature of the dry air and sends a signal to the control device. Dry air supply device to prevent moisture condensation from forming on the tools being cooled. (2) The moisture of the tool heated and cooled by a refrigerant during the operation according to claim 1 of the utility model registration claim, characterized in that a filter is provided between the housing and the pre-cooler/pre-dryer. Dry air supply device to prevent minute condensation from occurring. (3) heating during the operation according to claim 1, characterized in that the adjustable bypass duct is provided with an adjustment flap configured to completely close the duct; Dry air supply device for preventing moisture condensation on tools that are heated and cooled by a refrigerant. (4) Utility model registration claim 1, characterized in that the measuring device is disposed between two opposing tools, for example, when these tools can move relative to each other. Dry air supply device for preventing moisture condensation on tools that are heated and cooled by a refrigerant during the operation described in . (5) The control device comprises a processor that adjusts the flow rate of dry air in the bypass duct, the temperature of the refrigerant, and the operating speed of the tool in comparison with values from the temperature and absolute humidity diagrams of the air. A dry air supply device for preventing moisture condensation on tools that are heated and cooled by a refrigerant during operation as claimed in claim 1.
