Embodiment Construction

[0023] exist figure 1 , a schematic sectional view of the radial fan 11 is shown. By means of the radial fan 11 , the refrigerant is accelerated radially by the at least one impeller 16 , 26 of the compressor 27 and is deflected into the circuit of the refrigeration plant 1 , which is exemplified in the image 3 shown in.

[0024] By means of the radial fan 11 , the cooling medium is accelerated in the radial direction by the at least one impeller 16 , 26 of the compressor 27 and is led compressed into the gas pressure line 75 on the compression side of the refrigeration system 1 ( image 3 ). The impellers 16 , 26 are located on the shaft 17 which is driven by the motor 20 in the central region of the motor housing 21 . The motor 20 consists of the rotor 18 connected to the shaft 17 and the stator 19 fixed on the motor housing 21 . The area arranged outside the impellers 16 , 26 as seen from the shaft 17 forms the pressure side of the blower. Radial bearings 22 , 23 , in...

Abstract

The invention relates to a method for controlling at least one radial fan (11) in a refrigeration plant (1), wherein the radial fan (11) comprises a housing (21), in which A shaft (17) is rotatably supported in the casing, said shaft receiving at one end at least one impeller (16, 26) of a compressor (27) fixed to said casing (21), And the housing (21) includes at least one radial bearing (22, 23) and at least one axial gas bearing (31), and the shaft (17) is rotatably supported on the housing through the bearings (21), and the radial fan has a motor (20) driven by a rotor (18) and a stator (19), which drives the shaft (17), wherein the shaft (17) is associated with ) to detect the operating point of the shaft (17) and transmit the operating point to a control device (71) for determining the operating state of the radial fan (11). ).

Description

technical field [0001] The present invention relates to a method for controlling at least one radial fan in a refrigeration plant and to a refrigeration plant. Background technique [0002] A radial fan for gas lasers is known from DE 10 2010 001 538 A1. Such a radial fan comprises a motor consisting of a rotor and a stator between a first radial bearing and a second radial bearing, in particular a radial gas bearing. An impeller is provided on a shaft rotatably driven by a motor in the housing of the radial fan to turn the laser gas of the laser assembly over. The radial fan also includes an axial gas bearing positioned away from the impeller, wherein the motor is positioned between the axial gas bearing and the motor with a first radial bearing and a second radial bearing arranged directly adjacent thereto. between the impellers. The pressure medium is fed to the radial gas bearing and the axial gas bearing through channels in the housing in order to form a hydrodynamic...
