Detailed Description

To make the purpose and embodiments of the present application clearer, the following will clearly and completely describe the exemplary embodiments of the present application with reference to the attached drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

In the description of the present application, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing and simplifying the description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus are not to be considered limiting of the present application.

The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first", "second", may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.

Throughout the description of the present application, it is to be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in this application will be understood to be a specific case for those of ordinary skill in the art.

For a better understanding of the present application, reference is made herein to the prior art: the energy recovery system mainly comprises heat exchange equipment and a pipeline. The energy recovery system realizes energy recovery through heat exchange, the heat exchange function is mainly completed by heat exchange equipment, and the pipeline is only used for conveying media. A heat exchange core is usually arranged in the heat exchange equipment, and heat transfer between two paths of media is realized through the heat exchange core.

Referring to fig. 1, a heat exchange device is taken as a fresh air ventilator 1, and an energy recovery system is specifically described as an example of an air treatment system, and the energy recovery system includes the fresh air ventilator 1 and a pipeline 2.

The fresh air ventilator 1 comprises a casing 11, a heat exchange core 12 and a fan.

The casing 11 is provided with an indoor air supply outlet 15, an indoor air exhaust outlet 16, an outdoor air inlet 17 and an outdoor air outlet 18.

The heat exchange core 12 is arranged in the shell 11, and the outdoor air inlet 17 and the indoor air supply outlet 15 are communicated through the heat exchange core 12 to form an air supply duct; the indoor air outlet 16 and the outdoor air outlet 18 are communicated through the heat exchange core 12 to form an air exhaust duct.

The fan comprises a blower 13 and an exhaust fan 14, the blower 13 is arranged in the blowing air duct, and the exhaust fan 14 is arranged in the exhaust air duct.

The duct 2 includes a supply duct 21 and a discharge duct 22. One end of the air supply pipeline 21 is connected with the indoor air supply outlet 15, and the other end extends to the indoor room; the exhaust duct 22 has one end connected to the indoor exhaust port 16 and the other end extending to the indoor room.

When the energy recovery system operates, the blower 13 and the exhaust fan 14 are started, the indoor air of an indoor room enters the exhaust air duct of the fresh air ventilator 1 through the exhaust pipeline 22, the outdoor air enters the supply air duct of the fresh air ventilator 1 through the outdoor air inlet 17, after heat exchange is carried out on the two paths of air at the heat exchange core 12, the indoor air is blown to the outdoor through the outdoor air outlet 18, and the outdoor air is blown to the indoor room through the supply pipeline 21. Thereby, energy recovery is achieved while ventilating.

For example, in hot summer, the outdoor temperature is higher, the indoor temperature is lower due to the use of the air conditioner and other factors, and in this scenario, when the energy recovery system is operated, the outdoor air with higher temperature and the indoor air with lower temperature exchange heat at the heat exchange core 12, so as to reduce the temperature of the outdoor air blowing to the indoor, thereby recovering the energy of the air conditioner.

The heat exchange core 12 in the heat exchange equipment in the energy recovery system in the prior art is generally large in size, so that the heat exchange equipment is also large, can occupy a large space during installation, and is limited to installation in places with narrow installation space.

Therefore, based on the above problems, the inventive concept of the present application is proposed to transfer the heat exchange function of the energy recovery system to the pipeline, and to omit the heat exchange core 12 in the heat exchange device. Therefore, the volume of the system can be reduced, and the problem of installation limitation is solved.

The following detailed description of the application refers to the accompanying drawings in which:

in one aspect of the present application, referring to FIG. 2, an energy recovery system 100 is provided that includes a power source system 110 and a delivery conduit 120.

The power source system 110 may be an air driving system for driving air flow or a water pumping system for pumping water flow according to different media in actual situations.

Power source system 110 includes a first power source system and a second power source system. For convenience of description, the medium driven by the first power source is referred to as a first medium, and the medium driven by the second power source is referred to as a second medium.

Delivery conduit 120 is coupled to power source system 110. The conveying of the medium is realized by the conveying pipeline 120 under the action of the power source system 110.

The transfer line 120 includes a heat exchange line 130 for exchanging heat while transferring the medium.

Referring to fig. 3 to 6, the heat exchange pipeline 130 includes n layers of pipelines sleeved one on another, where n is an integer greater than 1. Wherein, the pipeline that arbitrary two adjacent covers were established is defined and is respectively skin honeycomb duct 131 and heat transfer honeycomb duct 132, and skin honeycomb duct 131 covers is established outside heat transfer honeycomb duct 132, and arbitrary heat transfer honeycomb duct 132 is the reference, and the heat exchange takes place for the medium that flows in this heat transfer honeycomb duct 132 and the medium that flows through outside this heat transfer honeycomb duct 132.

Specifically, referring to fig. 4 and 6, solid single arrows indicate the flowing direction of the first medium, hollow single arrows indicate the flowing direction of the second medium, solid double arrows indicate heat transfer, and the first medium and the second medium respectively exchange heat when flowing inside and outside the heat exchange flow guide pipe 132.

Illustratively, referring to fig. 3 and 4, n =2, the inner-layer pipe is a heat exchange guide pipe 132, the outer-layer pipe is an outer-layer guide pipe 131, and heat exchange occurs between a medium flowing between the heat exchange guide pipe 132 and the outer-layer guide pipe 131 and a medium flowing in the heat exchange guide pipe 132.

Exemplarily, referring to fig. 5 and 6, n =3, inward and outward, for the adjacent first layer of pipes and the second layer of pipes, the first layer of pipes is the heat exchange flow guide pipe 132, and the second layer of pipes is the outer layer flow guide pipe 131; for the adjacent second layer and third layer, the second layer is a heat exchange flow guide tube 132, and the third layer is an outer layer flow guide tube 131. The medium flowing between the second layer of pipelines and the first layer of pipelines and the medium flowing in the first layer of pipelines are subjected to heat exchange; and the medium flowing between the second layer of pipelines and the first layer of pipelines exchanges heat with the medium flowing between the third layer of pipelines and the second layer of pipelines.

The heat exchange is realized by the heat exchange pipeline 130 in the conveying pipeline 120 in the energy recovery system 100 of the application, and a huge heat exchange core body 12 is replaced, so that the volume of the system is smaller, the system can be installed in any place, and the installation convenience and flexibility of the system are improved.

Moreover, the heat exchange core 12 in the prior art has a large volume and is inconvenient to maintain, and the heat exchange pipeline 130 is used for exchanging heat to replace the heat exchange core 12, so that the convenience of maintenance is improved.

Moreover, the energy recovery system 100 of the present application is improved on the original pipeline, and the heat exchange function is added on the conveying function, so that the heat exchange core 12 in the prior art is omitted, and the product structure is simplified.

In addition, when heat exchange core 12 in the heat exchange equipment exchanges heat among the prior art, because heat exchange core 12's form is mostly cross flow or advection + cross flow, the built-in pressure loss is very big, is unfavorable for energy-conservation, and this application passes through heat exchange pipeline 130 heat transfer, and the pressure loss is less, and energy-conserving effect is better.

Since the heat exchange tubes 130 in this application can be of a multi-layer nested structure, except for the outermost and innermost layers, the tubes in the middle layer are both the outer flow guide tube 131 in the inner layer and the heat exchange flow guide tube 132 in the outer layer, and therefore,

the outermost outer layer draft tube 131 can isolate the energy exchange between the inside and the outside of the tube, can realize the functions of noise reduction and condensation prevention, can be made of flexible, rigid metal or hard nonmetal, and has internal and external force resistance greater than 1 Pa-2000 Mpa so as to meet the requirements of different application environments.

The heat exchange flow guide pipe 132 (the middle layer and the innermost layer of the pipeline) is made of a material with sensible heat or total heat energy exchange, can be a polymer film, aluminum/copper and alloy thereof, plastic, a biological film and the like, has a heat exchange coefficient of more than or equal to 0.2 and a water exchange capacity of more than or equal to 30mL/m ² 。

In some embodiments of the present application, referring to fig. 7-10, a plurality of heat exchange flow conduits 132 may be nested within one outer flow conduit 131.

The plurality of heat exchange flow guide pipes 132 correspondingly form a plurality of first passages, and the spaces between the plurality of heat exchange flow guide pipes 132 and the outer layer flow guide pipe 131 form second passages; the media in the plurality of first channels are in heat exchange with the media in the second channels.

Illustratively, and with particular reference to fig. 7 and 8, an outer draft tube 131 has three heat exchange draft tubes 132 therein. Three first passages are respectively formed in the three heat exchange guide pipes 132, and second passages are formed in spaces between the three heat exchange guide pipes 132 and the outer layer guide pipe 131.

In an application scenario, the medium in the same space can flow into the three heat exchange flow guide pipes 132 in three ways, so that the heat exchange efficiency between the first channel and the second channel can be improved by the form of flow division.

In another application scenario, three media in three spaces flow to the three heat exchange flow guide pipes 132 in a one-to-one correspondence manner, for example, the medium in the space (1) flows through the first heat exchange flow guide pipe 132, the medium in the space (2) flows through the second heat exchange flow guide pipe 132, and the medium in the space (3) flows through the third heat exchange flow guide pipe 132, so that simultaneous heat exchange in multiple spaces can be realized.

Therefore, the number of the heat exchange guide pipes 132 in the heat exchange pipeline 130 can be flexibly set according to actual use scenes, so that the application range of the heat exchange pipeline is widened, and the heat exchange efficiency can be improved.

According to some embodiments of the application, a plurality of heat transfer honeycomb ducts 132 are arranged at intervals in the outer honeycomb duct 131, so that the periphery of each heat transfer honeycomb duct 132 is ensured to be in contact with the medium of the second channel, and the problem of low heat transfer efficiency when the plurality of heat transfer honeycomb ducts 132 are accumulated is avoided.

In some embodiments of the present application, referring to fig. 11-13, in radial cross-section, the heat exchange flow guide 132 is corrugated with alternating peaks and valleys.

For example, in fig. 11, the radial cross section of the heat exchange guide pipe 132 is star-shaped, and the peak and the valley are triangular; in FIG. 12, the heat exchange guide tube 132 has rectangular peaks and triangular valleys; the edges of the peaks of the heat exchange draft tube 132 in fig. 13 again alternate in peak to valley.

The heat exchange guide pipe 132 is designed to be corrugated in special shape, so that the exchange area can be increased, and the energy exchange efficiency is improved.

It can be understood that, for the multi-layer sleeve structure, referring to fig. 14, the special-shaped design is also applicable, so that the heat exchange area of the multi-pipe is increased, and the efficiency of energy exchange is improved.

According to some embodiments of the present application, the relationship between the radial cross-sectional area S1 of the heat exchange draft tube 132 and the radial cross-sectional area S2 of the outer layer draft tube 131 satisfies: S1/S2 is more than 10 percent, so that the requirements of different pressure losses can be met while the heat exchange performance is met.

In some embodiments of the present application, the outer flow conduit 131 and/or the heat exchange flow conduit 132 is at least one of a straight tube, a threaded tube, or a corrugated tube in the axial direction. The straight pipe has lower cost, and the screwed pipe and the corrugated pipe can meet the bending requirements under different laying environments.

According to some embodiments of the present application, referring to fig. 15, the peaks on the heat exchange flow guide tube 132 are abutted against the inner wall of the outer layer flow guide tube 131, and the valleys on the heat exchange flow guide tube 132 and the outer layer flow guide tube 131 form a channel for medium circulation. Thus, the heat exchange guide tube 132 can be fixed in the outer guide tube 131 by the structure of the heat exchange guide tube itself.

In some embodiments of the present application, referring to fig. 16, the heat exchange flow conduit 132 is secured within the outer flow conduit 131 by a mounting bracket 140.

According to the length of the heat exchange pipeline 130, a fixed bracket 140 is arranged at every preset distance so as to support the position of the heat exchange guide pipe 132 in the outer layer guide pipe 131.

The fixing bracket 140 includes an outer ring portion 141, an inner ring portion 142, and a radiating portion 143. The outer ring portion 141 and the inner ring portion 142 are both in a ring shape, the inner ring portion 142 is located in the outer ring portion 141, and the plurality of radiation portions 143 are located between the inner ring portion 142 and the outer ring portion 141, so that the inner ring portion 141 and the outer ring portion 141 are connected, and meanwhile, the plurality of radiation portions 143 have intervals therebetween, so that the medium cannot be blocked from flowing.

The outer ring portion 141 abuts against the inner wall of the outer layer flow guide tube 131, and the inner ring portion 142 is sleeved outside the heat exchange flow guide tube 132 to support the position of the heat exchange flow guide tube 132 in the outer layer flow guide tube 131.

In another aspect of the present application, the above energy recovery system is specifically applied to air treatment, and therefore, an air treatment system 200 is provided, and referring to fig. 17, the air treatment system 200 includes a first wind-driving system 211, a second wind-driving system 212, and a conveying pipeline 120.

The transfer line 120 includes a heat exchange line 130, and the structure of the heat exchange line 130 is the same as that described above. Wherein a first channel 133 (channel indicated by solid arrow in fig. 17) is formed in the heat exchange flow guide tube 132, and a second channel 134 (channel indicated by hollow arrow in fig. 17) is formed in a gap between the heat exchange flow guide tube 132 and the outer layer flow guide tube 131. The first channel 133 is in communication with a first wind-driving system 211 and the second channel 134 is in communication with a second wind-driving system 212.

Under the action of the first and

second ventilation systems

211 and 212, the air of the first space exchanges heat with the air of the second space flowing through the second channel 134 while flowing through the first channel 133.

The air treatment system 200 of the present application, by the heat exchange pipeline 130 realizing heat exchange while conveying air, avoids the problem of large system volume and limited installation caused by the adoption of the heat exchange core 12 in the prior art.

And the laying of the heat exchange pipeline 130 is flexible in actual working conditions, so that the application range of the system is expanded.

The air supply system is used for driving outdoor air to flow indoors; and the air exhaust system is used for driving indoor air to flow to the outdoor.

The first channel 133 of the heat exchange line 130 communicates with the air supply system, and the second channel 134 in the heat exchange line 130 communicates with the air exhaust system. Thus, the outdoor air in the first passage 133 is heat-exchanged with the indoor air in the second passage 134.
