Multicontour multifunctional spiral heat exchanger operates in several modes as follows:
1. The one or several low pressure heat exchange media enters the multicontour multifunctional spiral heat exchanger through the inlet pipes for external connection of the low pressure heat exchange media 4, and passes through the channels for the passage of low pressure heat exchange media 10, and leaves multicontour multifunctional spiral heat exchanger through the outlet pipes for external connection of the low pressure heat exchange media 5. Wherein the three-ways valves or shut-off devices of connection units 6 of outlet
5 and inlet 4 pipes located sequentially next to each other are in a position that covers the connecting jumper between them. The one or several high pressure heat exchange media enters the multicontour multifunctional spiral heat exchanger through the distribution collector 11 and inlet manifolds 8, and passes through the channels of one or several high pressure media 7, and leaves multicontour multifunctional spiral heat exchanger through the outlet manifolds of the heat exchange one or several high pressure media 9 and the outlet distribution collector 15. Wherein the three-ways valves or shut-off devices 12, 13 and shut-off valves 14 of the distribution collector 11 and the three-ways valves or shut-off devices 16,17 and shut-off valves 18 of the distribution collector of the one or several high pressure media 15 are in a position that covers only connecting jumpers between them. The heat exchange in this mode occurs independently in each part of the channel 10 both for the one or several low pressure media and the one or several high pressure media. 2. The one or several low pressure heat exchange media enters the multicontour multifunctional spiral heat exchanger through the inlet pipes for external connection of the low pressure heat exchange media 4, and passes through the channels for the passage of low pressure heat exchange media 10, and leaves multicontour multifunctional spiral heat exchanger through the outlet pipes for external connection of the low pressure heat exchange media 5. Wherein the three-ways valves or shut-off devices of connection units 6 of outlet 5 and inlet 4 pipes located sequentially next to each other are in a position that covers the connecting jumper between them. The high pressure heat exchange medium enters multicontour multifunctional spiral heat exchanger through the distribution collector 11 and inlet manifolds 8. Wherein the three-ways valves or shut-off devices 12,13 and shut-off valves 14 are in a position that provides a unified flow of the one high pressure heat exchange medium through the inlet distribution collector 11 towards inlet manifolds 8.

The heat exchange in this mode occurs
independently in each part of the channel 10 for the one or several low pressure media, while the heat exchange for high pressure heat exchange medium occurs in the all parts of the heat exchanger from one source of high pressure medium. 3. When the three-ways valves or shut-off devices of connection units 6 of outlet
5 and inlet 4 pipes located sequentially next to each other are in a position that provides a unified flow of low pressure medium through all parts of the channel 10, the low pressure heat exchange medium enters the multicontour multifunctional spiral heat exchanger through the first inlet pipe for external connection of the low pressure heat exchange media 4, passes sequentially through the all parts of the channel 10 and leaves multicontour multifunctional spiral heat exchanger through the last outlet pipe for external connection of the low pressure heat exchange media 5.

Wherein the three-ways valves or shut-off devices 12,13 and shut-off valves 14 are in a position that provides a unified flow of the one high pressure heat exchange medium through the inlet distribution collector 11 towards inlet manifolds 8. The high pressure heat exchange medium passing through the channels 7 exits mu!ticontour multifunctional spiral heat exchanger through the outlet manifolds of the heat exchange one or several high pressure media 9 and outlet distribution collector of the one or several high pressure media 15, wherein the three-ways valves or shut-off devices 16, 17 and shut-off valves 18 are in position that provides a unified flow of the one high pressure heat exchange medium through the outlet distribution collector 15. In this mode the heat exchange occurs in the all parts of the channel 10 generally for the low pressure heat exchange medium, and the heat exchange for the high pressure medium occurs in the all parts of the heat exchanger from the one source of the high pressure medium.
4. When the three-ways valves or shut-off devices of connection units 6 of outlet 5 and inlet 4 pipes located sequentially next to each other are in a position that provides a unified flow of low pressure medium through all parts of the channel 10, the low pressure heat exchange medium enters the multicontour multifunctional spiral heat exchanger through the first inlet pipe for external connection of the low pressure heat exchange media 4, passes sequentially through the all parts of the channel 10 and leaves multicontour multifunctional
spiral heat exchanger through the last outlet pipe for external connection of the low pressure heat exchange media 5. The high pressure heat exchange media enters the multicontour multifunctional spiral heat exchanger through the distribution collector 11 and inlet manifolds 8, and passes through the channels of one or several high pressure media 7, and leaves multicontour multifunctional spiral heat exchanger through the outlet manifolds of the heat exchange one or several high pressure media 9 and the outlet distribution collector 15. Wherein the three-ways valves or shut-off devices 12, 13 and shut-off valves 14 of the distribution collector 11 and the three-ways valves or shut-off devices 16,17 and shut-off valves 18 of the distribution collector of the one or several high pressure media 15 are in a position that covers only connecting jumpers between them. In this mode the heat exchange occurs in the all parts of the channel 10 generally for the low pressure heat exchange medium, and the heat exchange for the several high pressure media occurs independently in each part of the channel 10.
5. Depending on the numbers of the channels both for low and high pressure heat exchange media the other combined modes of multicontour multifunctional spiral heat exchanger operations can be used.
