An apparatus for operating a compression-type refrigeration device with water as the refrigerant

摘要

An apparatus for operating a compression-type refrigeration device with water as the refrigerant, with a turbocharger (2), a capacitor (3), an evaporator (1), and at least one bypass (4) between the capacitor (3) and evaporator (1), wherein the means is designed in such a way that the bypass (4) during the on - and shut down of the turbo-compressor (2) is opened, characterized in that the at least one bypass (4) on the gas side between the capacitor (3) and evaporator (1) and is arranged with a which can be filled with liquid u - shaped tube (5) is provided, whereby the arms of the tube of the u - shaped tube (5) are so dimensioned that in the case of the corresponding amount of material in a liquid column of such a height can be formed, the at least the maximum pressure difference between the capacitor (3) and evaporator (1), wherein at the lowest point of the u - shaped tube (5) a drain (6) is mounted, and wherein the device is designed in such a way that the drainage (6) in the case of normal operation of which is closed and in the case of predefined operating states is opened.
