Problems solved by technology

[0004] However, the inventors of the present invention have found that the above-mentioned prior art uses both sewage and surface water as the heat exchange water source of the heat pump, and the two are independent of each other. When one or more of the heater and other components fails, the overall heat exchange area of ​​the independent heat exchange source cannot be used, making the economy and practicability low

Embodiment 1

[0057] Such as figure 1 As shown, this embodiment provides a water source heat pump composite system, which includes a circulating water system and a heat pump unit 4. Among them, there are at least two circulating water systems, and each circulating water system includes a water intake circulating pipe 1, a heat exchanger 2 and an intermediate water circulating pipe 3. Wherein, the heat exchanger 2 in each circulating water system is respectively connected with the water intake circulation pipe 1 and the intermediate water circulation pipe 3 to realize the heat exchange between the water in the water intake circulation pipe and the intermediate water in the intermediate water circulation pipe. . The heat pump unit 4 is connected to the intermediate water circulation pipeline 3 of each circulating water system, and is used to transfer the heat of the intermediate water to the heat pump unit 4. The intermediate water circulation pipeline 3 includes a first pipeline 31 and a sec...

Embodiment 2

[0059] Such as figure 1 As shown, this embodiment provides a water source heat pump compound system. Compared with the previous embodiment, the first pipe 31 of the intermediate water circulation pipe 3 in this embodiment is also provided with a water collector 33 to allow The intermediate water after heat exchange in the heat exchanger 2 flows through the water collector 33, and then flows into the heat pump unit 4 for heat exchange heat treatment. The second pipeline 32 of the intermediate water circulation pipeline 3 is also provided with a water separator 34, so that the intermediate water after heat exchange by the heat pump unit 4 flows through the water separator 34, and then flows into the corresponding heat exchanger 2 for heat exchange treatment. .

[0060] In this embodiment, through the above arrangement, the intermediate water of different intermediate water circulation pipelines 3 flows into the water collector 33, and then flows into the heat pump unit 4 at a const...

Embodiment 3

[0063] This embodiment provides a water source heat pump compound system. Compared with the above embodiment, there are two circulating water systems in this embodiment, specifically a first circulating water system and a second circulating water system. Among them, the water intake circulation pipeline of the first circulating water system is a sewage circulation pipeline, and the water intake circulation pipeline of the second water circulation system is a surface water circulation pipeline.

[0064] The sewage water source or the surface water source flows through the heat exchanger through the sewage water intake pump 12 or the surface water intake pump respectively, transfers heat and returns to the sewage water source or surface water source, and the intermediate water that exchanges heat with the water source in the heat exchanger passes through the intermediary The water pump flows into the water collector 33 and from the water collector to the heat pump unit 4. After the ...

Abstract

The invention, which relates to the technical field of heat pump air conditioning, discloses a water-source heat-pump composite system. With the system, technical problem of low economy and practicability of the existing water source heat pump system in the prior art can be solved. According to the technical scheme, the composite system comprises at least two circulating water systems. Each circulating water system contains a water taking circulating pipeline, a heat exchanger, an intermediary water circulation pipeline; and the heat exchanger is connected with the water taking circulating pipeline and the intermediary water circulation pipeline. A heat pump set is connected with the intermediary water circulation pipeline of the circulating water system. Each intermediary water circulation pipeline includes a first pipeline and a second pipeline; and intermediary water inside the first pipeline flows to the heat pump set and intermediary water inside the second pipeline flows to the heat exchanger. The first pipelines of all circulating water systems are connected by a first normally-closed pipeline; and the second pipelines of all circulating water systems are connected by a second normally-closed pipeline. The provided water-source heat-pump composite system has high economy and practicability.

Description

Technical field [0001] The present invention relates to the technical field of air conditioning, in particular to the technical field of heat pump air conditioning, and in particular to a water source heat pump compound system. Background technique [0002] A heat pump is an energy-saving device that can convert unusable low-level heat energy (such as heat energy contained in soil and water) into usable high-level heat energy. Ground and water source heat pumps are gradually applied to the air-conditioning industry due to their advantages in energy saving, environmental protection, high efficiency, and economy. However, the application of ground source heat pumps requires a large buried pipe area, and the development and utilization of groundwater is restricted to varying degrees throughout the country. Sewage and surface water not only have a large water source, but also support their development and utilization throughout the country. [0003] In practical applications, especial...
