Description

Outdoor heat exchange system and air conditioning system

Technical Field

The utility model relates to a mechanical equipment field particularly, relates to an outdoor heat exchange system and air conditioning system.

Background

In recent years, with the increasingly prominent energy and environmental problems, ground source heat pump air conditioning systems are more and more widely applied. The ground source heat pump air conditioning system mainly comprises an outdoor heat exchange system, a heat pump machine room and an indoor tail end system, wherein the design and construction of the outdoor heat exchange system are particularly important, and whether the whole air conditioning system can stably run for a long time or not is determined.

To save land and be limited by green conditions, most outdoor buried heat exchange holes are designed under the bottom plate of the building basement. The single underground heat exchange hole is connected through a horizontal pipeline, a plurality of horizontal pipelines penetrate upwards along the side wall of the underground garage and are connected to the ground source water collecting and distributing device, and finally the horizontal main pipe is connected to the heat pump machine room.

To the area of the continuous pipe of level under the bottom plate of building ground storehouse, because the construction order of the continuous pipe of level and building pile foundation cushion cap is mostly subregion cross operation, the displacement probably appears in the pipeline during backfilling, destroys original pipeline when leading to later stage building pile foundation cushion cap to excavate the slot.

For example, in the current construction, the common pipe running mode of the multiple same water supply (return) main pipes is that the pipes run on the same layer of the same ditch, the multiple same water supply (return) main pipes share the same pipe ditch, and the pipelines are horizontally laid. Because the waterproof requirement of bottom plate of underground garage is higher, horizontal pipeline can not follow the bottom plate and directly penetrate, and the side wall of people's air defense region, function computer lab does not allow to penetrate, and building red line is too close with the structure wall body, does not allow to do the inspection shaft outdoors, consequently can appear the condition that needs long distance level to walk the pipe, and pipeline single length is more than 200 meters promptly. The phenomenon of bending and deviation of pipelines can occur in a multi-path same-kind water supply (return) main pipe (hereinafter, collectively referred to as a buried pipe) buried in the ground due to the overlong distance of the pipe.

For example, in an area with limited pipe running space, for example, a pile foundation, a local drop plate, a post-cast strip and the like exist under a building, the pipe running method of the same ditch layering is often adopted in construction, a plurality of same water supply (return) main pipes share a pipe ditch, and the pipe is paved in upper and lower layers. The pipe conveying mode also has the problems of the same-ditch same-layer pipe conveying mode, and the mode also has the phenomenon that the distance between the upper layer pipeline and the lower layer pipeline is close during backfilling, and the position of the upper layer pipeline is moved to extrude fine sand under the influence of gravity, or the upper layer pipeline and the lower layer pipeline are contacted with each other and are stacked and damaged due to uneven backfilling of the fine sand.

Because outdoor heat exchange system is secret underground works, and buried heat exchange hole and horizontal pipeline of most projects are all located building ground storehouse bottom plate below, and the design has the limitation, and can't observe after the construction, for permanent, unrepairable engineering, consider whole air conditioning system's long-term steady operation, when carrying out horizontal pipeline design and construction, the risk that the destruction appears in the pipeline should be avoided as far as possible, reduces pipeline construction's potential safety hazard. Therefore, a reliable and stable method for laying underground pipes and measures for protecting the underground pipes are needed.

As shown in fig. 1 to 7, according to the embodiment of the present invention, the outdoor heat exchange system includes a ground pipe 10 and a ground pipe support structure 20, the ground pipe support structure 20 is provided with at least two spacing accommodating grooves 21 for accommodating the ground pipe 10, the spacing accommodating grooves 21 are at least two, one of the spacing accommodating grooves 21 and the other spacing accommodating groove 21 are arranged at an interval in the horizontal direction, and/or one of the spacing accommodating grooves 21 and the other spacing accommodating groove 21 are arranged at an interval in the vertical direction.

In this outdoor heat exchange system set up buried pipe 10 in buried pipe bearing structure 20's spacing holding tank 21, can utilize spacing holding tank 21 to inject buried pipe 10's position to because phenomena such as the skew, the bending that length overlength leads to make between the buried pipe 10 extrude the collision each other and cause the damage when can preventing buried pipe 10 level walk pipe. Through using buried pipe bearing structure 20 to support and spacing buried pipe, both prevented the buried pipe skew, guaranteed the interval between the buried pipe 10 again, guarantee that can not extrude each other and cause the damage between the buried pipe 10, promoted the reliability that the buried pipe walked the pipe, avoid the risk that the pipeline appears destroying, reduced pipeline construction's potential safety hazard.

The buried pipe support structure 20 may be an integrated structure or a separate structure. As shown in fig. 1 and 5, taking the ground pipe support structure 20 as an integrated structure as an example, the ground pipe support structure 20 is provided with a first groove group, the first groove group is located on a first side wall of the ground pipe support structure 20, and the first groove group includes at least two limiting accommodating grooves 21 arranged at intervals along a horizontal direction. For the buried pipe 10 arranged in the same trench in the trench 30, the buried pipe 10 can be limited by the limiting and accommodating groove 21 in the first groove group. Because spacing holding tank 21 sets up along the horizontal direction interval, consequently can keep the distance between the buried pipe 10 of horizontal arrangement to prevent buried pipe 10's skew, and fixed buried pipe 10 guarantees that it can not produce bending deformation, prevents that buried pipe 10 from warping and mutual extrusion from causing the pipeline to destroy.

Optionally, in order to improve the limiting effect on the buried pipe 10, the cross-sectional shape of the limiting accommodating groove 21 is adapted to the cross-sectional shape of the buried pipe 10. For example, if the buried pipe 10 is a circular pipe, the position-limiting accommodation groove 21 may be a semicircular groove. Of course, the two may not be adapted to each other, for example, the buried pipe 10 is a circular pipe and the limiting and receiving groove 21 is a square groove.

Optionally, in order to improve the adaptability of the underground pipe support structure 20, a second groove set is further disposed on the underground pipe support structure 20, the second groove set is located on a second side wall of the underground pipe support structure 20, the second side wall and the first side wall are spaced from each other in the vertical direction, and the second groove set includes at least two limiting receiving grooves 21 spaced from each other in the horizontal direction. For the buried pipes 10 which are arranged in the pipe trench 30 in a stacking manner with the trench, the buried pipes 10 on the lower layer can be accommodated and limited through the limiting and accommodating groove 21 of the first groove group, and the buried pipes 10 on the upper layer can be accommodated and limited through the limiting and accommodating groove 21 of the second groove group. Therefore, the buried pipes 10 on the same layer can be limited, and the buried pipes 10 on two adjacent layers can also be limited, so that the buried pipes 10 on the upper layer are prevented from being bent under the action of gravity to extrude the buried pipes 10 on the lower layer.

It should be noted that the size of the space between the limiting accommodating grooves 21 in the first groove set may be the same as or different from the size of the space between the limiting accommodating grooves in the second groove set. The interval between two adjacent limit accommodating grooves 21 in the first groove group can be the same or different.

Optionally, in order to ensure the stability of the pipe distribution, the projection of the limit accommodating groove 21 of the second groove group in the vertical direction is located between two adjacent limit accommodating grooves 21 in the first groove group, so that the buried pipe 10 on the upper layer is located in the gap between two buried pipes 10 on the lower layer when the pipe distribution is stacked, and the buried pipe 10 is prevented from being deformed.

Alternatively, in order to reliably support the buried pipe 10, the buried pipe support structure 20 is plural and is provided at intervals in a length direction of the buried pipe 10. For example, one underground pipe support structure 20 is provided every 20 to 30 meters.

Optionally, the buried pipe support structure 20 is an extruded polystyrene board. The extruded polystyrene board is named as extruded polystyrene foam board, is made of polystyrene resin and polymer, and is one kind of environment protecting heat insulating material with excellent anticorrosive, ageing preventing, moisture preventing and heat insulating performance. The buried pipe supporting structure 20 made of the material has high structural strength, can keep the inherent shape without deformation, has outstanding heat preservation performance and can realize a good heat preservation effect.

Because the buried pipe fixing piece 23 and the main body 22 are detachable, different buried pipe supporting buried pipe fixing pieces 23 can be replaced in different use scenes, so that the buried pipe supporting structure can adapt to different use requirements, the adaptability is better, and the positions and the number of the limiting accommodating grooves 21 on the buried pipe supporting structure 20 can be adjusted according to requirements. In addition, the spacing size between spacing holding groove 21 on different buried pipe fixings 23 can be different to adapt to different walk pipe interval requirements.

The cooperation between the main body 22 and the buried pipe fixing 23 may be set according to specific needs. For example, at least one side wall surface of the main body 22 is provided with a first guide protrusion 221 engaged with the buried pipe fixing member 23, and the buried pipe fixing member 23 is provided with a first guide sliding groove engaged with the first guide protrusion 221.

For another example, at least one side wall surface of the main body 22 is provided with a second guiding sliding groove engaged with the buried pipe fixing member 23, and the buried pipe fixing member 23 is provided with a second guiding protrusion engaged with the second guiding sliding groove.

Therefore, the phenomena of bending and deviation of the pipeline caused by overlong distance of the pipeline and no fixing measures can be avoided.

The specific use process of the device in the scene with limited walk tube space is as follows: because the pipe-passing space is limited, the buried pipes 10 in the construction adopt a pipe-passing mode layered with the trench, namely, the buried pipes 10 share the pipe trench 30, the buried pipes 10 are divided into upper and lower layers, and the buried pipes 10 in the same layer are arranged in a line in the horizontal direction. According to the use requirement, a buried pipe supporting structure 20 is arranged above the buried pipe 10 at the lower layer at intervals of 20-30 meters, so that the buried pipe 10 in the horizontal direction is fixed and spaced through the buried pipe supporting structure 20, and meanwhile, the layered laying support of the buried pipe 10 can be realized in the vertical direction. Therefore, the phenomenon of overlying damage of the buried pipes 10 can be avoided, the firmness and stability of installation are ensured, and a certain distance is reserved between every two buried pipes 10.

After the buried pipe 10 is laid and the on-site constructor checks that the buried pipe 10 is correct, the buried pipe 10 can be backfilled by fine sand, and then the graded gravel 40 is used for covering, so that the backfilling of the pipe trench 30 is realized.

According to the utility model discloses an on the other hand provides an air conditioning system, and air conditioning system includes foretell outdoor heat transfer system.

The buried pipes 10 of the outdoor heat exchange system of the air conditioning system are horizontally routed in a long distance under the bottom plate of the building ground reservoir, the buried pipes 10 share a pipe ditch 30, the buried pipes 10 are arranged in a horizontal direction in a straight line, and a buried pipe supporting structure 20 (such as an extruded polystyrene board) is arranged above the buried pipes 10 according to the actual situation on site at intervals of 20-30 meters so as to fix and space the buried pipes 10 in the horizontal and vertical directions, so that the problems that the buried pipes 10 are contacted with each other to cause heat exchange interference, extrusion, lamination, damage and the like due to the fact that the buried pipes 10 are not fixed and isolated when the pipes are routed are effectively solved, the construction potential safety hazards of the buried pipes 10 can be effectively reduced by the measures, and the long-term stable operation of the whole air conditioning system is ensured.

From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: .

Use buried pipe bearing structure to support and spacing buried pipe, compare with prior art, buried pipe bearing structure not only can avoid buried inter-pipe mutual contact to take place heat transfer and disturb, can also avoid the pipeline extrusion, fold and press the phenomenon of destruction.
