Definitions

the invention relates to a compressor unit according to the preamble of claim 1.
Such an assembly is known from DE-C-43 27 003, from which the preamble of claim 1 is based.
the exhaust air emerging from the liquid separator is fed to an after-cooling device, via which the suction air is also conducted.
This results in a heat exchange between the cooler suction air and the exhaust air heated by the compression process, which results in cooling of the exhaust air.
part of the water vapor contained in the exhaust air is condensed.
the condensed water is fed back into the operating fluid circuit so that the consumption of operating fluid is reduced. Despite this reduction in the consumption of operating fluid, this still has to be added from time to time. It has been shown that the degree of separation of water vapor from the exhaust air cannot be increased significantly by a larger dimensioning of the aftercooling device.
a separate cooling air flow for the second aftercooling device is unnecessary in that it lies in the cooling air flow of the heat exchanger.
the second aftercooling device can be structurally combined with the heat exchanger, which results in a significant space saving.
a suction line 4 is connected to the inlet opening 1 of the liquid ring machine 2 of the compressor unit 3.
the outlet opening 5 of the liquid ring machine 2 is connected to a liquid separator 6.
the medium (air) to be compressed, including part of the operating liquid, is expelled via the outlet opening 5 and fed to the liquid separator 6.
a third post-cooling unit 14 can also be arranged between the second post-cooling unit 8 and the first post-cooling unit 7. However, the third post-cooling unit 14 can, as indicated by dashed lines, flow upstream of the second post-cooling unit 8.
the third post-cooling unit 14 is connected with its primary circuit to the exhaust line 9 of the liquid separator 6, and thus to the outlet line of the secondary circuit of the first after-cooler 7.
the compressor unit 3 also has a heat exchanger 10 which is connected to a return line 11 for the operating liquid leading from the liquid separator 6 to the liquid ring machine 2.
a fan 12 is assigned to the heat exchanger 10 and generates a cooling air flow 13 flowing through the heat exchanger 10.
the second post-cooling unit 8 is structurally combined in such a way that the cooling air flow 13 also flows through it. This can be achieved by arranging these elements axially one above the other or one above the other in height.
the condensate obtained in the after-cooling units 7, 8 and 14 is returned to the operating fluid circuit by means of corresponding lines, which are not specifically shown in the drawing.
the exhaust air flowing out of the liquid separator 6 first flows through the second after-cooling unit 8 and is cooled accordingly, which leads to condensation of part of the water vapor contained in the exhaust air. Subsequently, in the third and first post-cooling units 14 and 7 there is a further cooling of the exhaust air and thus a further condensation of water vapor.
the exhaust air in the exhaust air when leaving the after-cooling unit 7 or the proportion of water vapor still contained in the third after-cooling unit 14 is not higher than the proportion of water vapor when the suction air enters the first after-cooling unit 7. So there is no water consumption at all.
liquid separator 6 is arranged in the cooling air flow of the heat exchanger 10. This is possible, in particular, if the compressor unit is designed as a structural unit, by means of a corresponding structural arrangement of the liquid separator in the structural unit.
the liquid separator can advantageously also be provided with cooling fins that increase its surface area.
