The two groups of condensation pipe groups are mutually separated, and the two groups of condensation pipe groups can be isolated by air and can also be provided with heat insulation plates. Two sets of condenser pipe groups can supply two kinds of media to pass through respectively, do not influence each other moreover.

As shown in fig. 1 and fig. 2, the first condensation tube group 20 includes a first input port 21 for a first medium to enter and a first output port 25 for a first medium to exit, the first input port 21 is located at an end of the first condensation tube group 20 close to the spraying device, and the first output port 25 is located below the first condensation tube group 20. The first condensation tube group 20 is formed by connecting three sets of condensation units in series, namely a first condensation unit 231, a second condensation unit 232 and a third condensation unit 233. The first condensing unit 231, the second condensing unit 232, and the third condensing unit 233 are sequentially fixed to the frame 10 from top to bottom. By sequentially arranging three groups of condensing units, the circulation path of the medium can be increased as much as possible in a limited space. The first condensing unit 231 and the second condensing unit 232, and the second condensing unit 232 and the third condensing unit 233 are connected in series. Four rows of parallel condensing circuits 27 are provided in the first condensing unit 231, the second condensing unit 232, and the third condensing unit 233, respectively. The parallel condensing loop 27 design greatly ensures the medium over-flow. The mutual stack that staggers between every row of condensation return circuit 27 to increased the water film that forms after spraying water sprays and the area of contact of condensation return circuit 27, reduced the shower water and flowed down from the clearance between the condensation return circuit 27, the waste of the shower water that causes, greatly reduced the rate of floating of shower water.

As shown in fig. 1, 2, 3 and 4, each row of condensing loops 27 is provided with three sets of condensing loops 27 side by side, each set of condensing loops 27 is independent and not communicated with each other, each set of condensing loops 27 is composed of a water inlet condensing pipe 271 and a water return condensing pipe 272, and the water inlet condensing pipe 271 and the water return condensing pipe 272 are connected in series. The first condensing unit 231, the second condensing unit 232 and the third condensing unit 233 are identical in structure and installation manner. The first condensing unit 231 is provided with four rows of condensing loops 27, each row is provided with three groups, and twelve groups of condensing loops 27 are provided, namely twelve inlet water condensing pipes 271 and twelve return water condensing pipes 272.

However, two adjacent rows of return water condensation pipes 272 are connected with the inlet water condensation pipe 271 in series. The connection mode and advantages are the same as the connection mode of the water inlet condensation pipe 271 and the water return condensation pipe 272 in the same condensation unit, and are not described again here.
