Definitions

  • the at least one control device is further preferably designed so that when the changeover valve is switched so that a second outlet is opened, the mixing valve is switched so that its second input is as far as possible and preferably completely closed.
  • the control device 52 controls the changeover valve 10 such that by displacement of its valve element 50 either a flow path from the circulating pump unit 6 to the first heating circuit flow connection 22 or alternatively to the process water heat exchanger 12 is given.
  • the mixing valve 8 becomes preferable so controlled that its valve element 40 is located so that the second input 36 is substantially closed, so that the pump unit 6 sucks via the input port 14 of the heat source 16 heated heat carrier and promotes through the hot water heat exchanger 12.
  • the switching valve 10 is in the other switching position, the flow path to the hot water heat exchanger 12 is closed and the flow path to the first heating circuit flow connection is opened. In this position, the mixing function of the mixing valve 8 comes into play.
  • connection to the second heating circuit feed connection 28 branches off between the input connection 14 and the first input 34 of the mixing valve 8, so that the second heating circuit 26 is supplied with heat transfer medium having the flow temperature Heat source 16 is supplied is supplied.
  • To convey the heat carrier through the second heating circuit 26 serves the central circulation pump 18th
  • the mixing valve 8 is, as described, identical. It has a first valve seat 70 on the first input 34 and a second valve seat 72 on the second input 36.
  • the valve seats 70 and 72 are also facing each other, so that the valve element 40 is located between them and can optionally come to rest on one of the valve seats 70 and 72.
  • the valve element 40 is also attached to a lever 66, which is led out of the valve housing 56 by a seal 68 and is moved there by the stepping motor 38.
  • the lever 66 also pivots about a pivot axis in the region of the passage in the seal 68.
  • the output 32 of the mixing valve 8 branches off from the space between the valve seats 70 and 72, as well as the input 42 of the switching valve 10 in the space between the Valve seats 62 and 64 opens.
  • Fig. 7b shows a second switching position in which the valve element 98 is rotated about the rotation axis X so that the switching opening 100 is located above the connection opening 94 of the first output 44 and the Switching port 96 of the second output 46 is closed.
  • the first switching opening 112 is formed so long in its curved extension direction that it continues to lie above the connection opening 90 of the first input 34. D. h., In this switching position, the flow path to the hot water heat exchanger 12 is closed and it is now promoted on rotation of the impeller 78, the liquid heat carrier through the first output 44 to the first heating circuit flow connection 22.
  • FIGS. 7d to 7f show positions of the valve element 98 for different mixing ratios.
  • the second switching opening 114 is formed so long in its arcuate extension direction that it completely covers the connection opening 94 of the first outlet 44 in all angular positions of the valve element 98 with respect to the longitudinal axis X, so that the first outlet 44 is open.
  • Fig. 7d shows a center position in which the first switching opening 112 is positioned so that the connection openings 90 and 92 of the inputs 34 and 36 covered by the same amount, and preferably both are fully open.
