[0001] The present invention relates to the technical field of sewage source heat pumps, and in particular to a dual-heat source heat pump integrated machine. Background Art

[0002] Sewage source heat pumps are safe, environmentally friendly, energy-saving, efficient, and turn waste into treasure, and have been widely recognized in the market. However, in actual application, they also bring various problems to customers, especially easy corrosion, serious dirt and blockage, high maintenance frequency, and difficult maintenance.

[0003] At present, sewage source heat pumps with direct sewage heat exchangers are available on the market, which can solve problems such as easy corrosion, serious dirt and blockage, high maintenance frequency, and difficult maintenance. However, the quality of installation projects is also uneven, and various problems arise, such as on-site pipeline installation problems, matching and linkage problems between various equipment, etc. The subsequent operating costs are high, and after-sales maintenance is complicated. There are often problems such as insufficient sewage volume and low operating efficiency of air source heat pumps in winter. The single heat source equipment has low operating efficiency under certain environments. For this reason, we propose a dual-source heat pump all-in-one machine. Summary of the invention

[0004] In view of the above problems existing in the prior art, one aspect of the present invention is to provide a dual-heat source heat pump all-in-one machine.

[0006] Preferably, the second valve, the third valve, the fourth valve and the fifth valve are used to control the on-off of the water pipelines of the first water pump and the second water pump.

[0007] Preferably, the first water pump and the second water pump are connected in parallel, one for backup and the other for use.

[0008] Preferably, the first valve and the seventh valve are used to control the on-off of the user-side water inlet main pipe and the user-side water outlet main pipe, respectively.

[0009] Compared with the prior art, the dual-heat-source heat pump integrated machine provided by the present invention has the following beneficial effects:

[0010] (1) It adopts a special container structure and can be placed outdoors together with a full-liquid air source heat pump to prevent corrosion;

[0011] (2) The integrated machine is hoisted as a whole, which is easy to install. When it is transported to the site, only some pipes need to be connected;
