Description

Technical Field

[0001] The utility model relates to the technical field of heat pump hybrid technology, and particularly relates to a hot water air-conditioning device combining a ground source heat pump and an air source heat pump. Background Technique

[0002] A ground source heat pump, also known as a geothermal heat pump, is a device that uses the heat in the underground soil or water source for heating, cooling, and providing hot water. The ground source heat pump system circulates a liquid through underground pipes and utilizes the relatively stable temperature of the earth's surface layer to improve energy efficiency. It is a highly efficient and renewable energy technology, and its main advantages lie in high energy efficiency, good stability, and long service life.

[0003] An air source heat pump is a device that uses the heat in the air to heat or cool a building. It extracts heat from the air through a compression-expansion cycle and transfers it indoors or extracts heat from indoors and releases it into the air. Its main advantages are high energy efficiency, environmental protection, multi-functionality, and convenient installation. However, its main disadvantage is that its efficiency is affected by the climate. In extremely cold regions, the efficiency of the air source heat pump will decrease because the outside air temperature is too low, the heat extraction efficiency is reduced, and the noise is high.

[0004] The above heat pumps are the mainstream energy heat pump systems in the prior art. When used alone, they have different advantages and disadvantages. Therefore, if the heat output by the two heat pumps is combined and the heat is input into the application scenario by a blower, it is a good form of use. However, the simple combination method in the prior art will cause the power of the main heat pump supply equipment to be different under the same heat exchange demand of the two heat pumps due to the influence of the external environment, resulting in different temperatures output by the heat exchanger at the use end. Therefore, under the condition of the same wind speed, the evaporator under the working condition with higher heat exchange demand and the evaporator under the working condition with lower heat exchange demand will compensate each other, resulting in a decrease in the total output temperature. Only by overloading the evaporator at the end with lower heat exchange demand can the heat exchange demands of the two evaporators be made equivalent to ensure the maximum output efficiency. Therefore, in most cases, the simple mixed hot water air-conditioning device will cause the problem of relatively low temperature output efficiency, and it will also cause the end with low heat extraction efficiency to start overloading or consume a large amount of electric energy to increase the compression or evaporation speed to ensure the higher heat exchange demand inside, resulting in the problem of too high overall use pressure of the equipment. In view of the above problems, a hot water air-conditioning device combining a ground source heat pump and an air source heat pump is specifically proposed. Content of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-9 , the present invention provides a technical solution: a hot water air conditioner device combining a ground source heat pump and an air source heat pump, including an evaporator 1, an air duct component 2 is assembled outside the evaporator 1, and an air supply mechanism 3 is assembled on the other side of the air duct component 2;

[0033] The air outlet of the air supply mechanism 3 can be unidirectionally displaced in the vertical direction of the air supply direction;

[0034] The evaporator 1 includes a first circulation component 14 and a second circulation component 15. The first circulation component 14 and the second circulation component 15 are respectively connected to the heat pump. The first circulation component 14 and the second circulation component 15 are arranged in reverse, and the first circulation component 14 and the second circulation component 15 are installed in an equidistant and staggered overlapping manner;

[0035] The air duct component 2 includes a support frame 21. The cross-section of the support frame 21 is "J"-shaped. The "J"-shaped sealing positions of the two sets of support frames 21 are symmetrically assembled in the reverse direction on the outer wall of the first circulation component 14 or the second circulation component 15. A heat sink 23 is vertically fixed between the "J"-shaped opening positions of two adjacent support frames 21;

[0036] The vertical cavity formed between the heat sink 23 and the support frame 21 constitutes a heat dissipation air duct, and a compensation pipe 25 is butted on the outside of the heat dissipation air duct;

[0037] The air supply mechanism 3 includes an air inlet pipe 31. An air outlet pipe 33 is integrally formed on the outside of the air inlet pipe 31, and the air outlet pipe 33 is inserted into the inside of the compensation pipe 25.

[0038] The utility model provides a combined hot water air conditioner device composed of a circulation component with two sets respectively connected to two different heat source heat pumps such as a ground source heat pump or an air source heat pump. It uses a zoning form in which high-speed airflows at different positions are introduced into an equal-spacing air duct to form an active air current and a passive adsorption air current inside the air duct. Furthermore, when the heat exchange requirements of different heat sources on both sides of the same air duct are different, the flow rate ratio is adjusted specifically to achieve the purpose of stably mixing and outputting the air current temperature, effectively solving the problem of low output efficiency of existing combined hot water air conditioner devices.

[0039] Specifically, the second circulation component 15 includes an "S"-shaped circulation pipe 12. A number of sets of the circulation pipes 12 are arranged in a linear array and stacked. Connectors 11 are welded to the outside of two of all the pipe joints of the circulation pipe 12, and the other pipe joints of the circulation pipe 12 are welded and connected through connecting pipes 13 to form a three-dimensional stacked circulation pipeline.

[0040] Specifically, the first circulation component 14 has the same structural composition as the second circulation component 15.

[0041] The first circulation component 14 and the second circulation component 15 are respectively two sets of three-dimensional stacked reciprocating circulation pipeline components. The two sets of components are installed in a left-right staggered manner in the legend. Therefore, inside a heat dissipation air duct formed by two sets of support frames 21, the top and bottom are respectively two sets of independent horizontal circulation pipelines, corresponding to two heat sources.

[0042] Specifically, a docking groove 22 is opened on the outer wall of the "Ji"-shaped closed side of the support frame 21. The docking groove 22 closely fits on the outer wall of the circulation pipe 12. The support frame 21 is clamped and arranged through a back-to-back structure, and can clamp and position a group of circulation pipes 12. Subsequently, the gaps between the two sets of support frames 21 are supported by evenly distributed heat dissipation fins 23 to form an air duct, thereby forming a number of vertically stacked air duct structures. The top and bottom of the air duct structure respectively expose the corresponding circulation pipelines, and the heat dissipation fins 23 assist in heat dissipation by utilizing the heat conduction characteristics of the metal.

[0043] Specifically, grooves with the same shape as the outer wall of the circulation pipe 12 are punched on the top and bottom surfaces of the heat dissipation fin 23, and support pieces 24 are formed on the outer sides of the edges of the grooves.

[0044] The main heat dissipation function of the heat dissipation fin 23 is the same as that of existing heat dissipation fins. It is mainly made of a thin and easily heat-conductive metal sheet by stamping. While punching the groove, a support piece 24 with the same arc as the groove is directly formed by rolling. The support piece 24 is used for close contact with the circulation pipe 12 to improve the heat conduction efficiency.

[0045] Specifically, the cross-section of the circulation pipe 12 is oval. The circular pipe is directly processed into the required oval-section circulation pipe 12 by means of roll pressing. And during the pressing process, the program can be directly set to turn to form the circulation pipe 12 with a single horizontal plane structure. The purpose of setting the structure to be oval is mainly to increase the contact position between the circulation pipe 12 and the support piece 24 at the upper and lower installation positions and the contact area with the air flow, so as to improve the heat exchange efficiency.

[0046] Specifically, one set of the air inlet pipes 31, several sets of the compression pipes 32 and several sets of the air outlet pipes 33 are taken as a group. The left and right two groups are inserted into the inside of the compensation pipe 25 in a crosswise manner. The set length of the compensation pipe 25 can respectively fill the vacancies of the heat dissipation air ducts corresponding to the positions where any compensation pipe 25 is located. And the outermost vertical directions of the compensation pipes 25 are in an aligned state.

[0047] As Figures 1-3 shown, the air supply mechanism 3 is divided into two parts. Among them, one set of the air inlet pipes 31 on the left and right parts are respectively used. And half of the length of the compression pipe 32 is welded, and the air outlet pipe 33 with the same length as the inside of the compensation pipe 25 is eccentrically welded outside the compression pipe 32. During use, the two sets of structures are staggered. The adjacent air outlet pipes 33 of the upper and lower two sets can be respectively inserted into the inside of the compensation pipe 25. Therefore, while the air can be supplied to the inside of the air ducts communicated with each compensation pipe 25, the purpose of adjustment can be achieved. Since the overall structure is distributed in a staggered manner, when adjusting the distance between the air outlet pipe 33 and the heat dissipation air duct, the two sets of structures are adjusted in the reverse direction to achieve the same adjustment purpose.

[0048] Specifically, an inclined compression pipe 32 is arranged between the air inlet pipe 31 and the air outlet pipe 33.

[0049] Specifically, a contraction port 34 with a gradually decreasing distance from the air supply and air outlet directions is opened inside the air outlet pipe 33.

[0050] The whole air supply mechanism 3 is connected to a conventional fan, generally adopting a drum fan structure. After guiding the air flow through the intake pipe 31 on the outside and compressing it through the compression pipe 32, the air flow is initially accelerated and finally ejected from the contraction port 34 to achieve the purpose of final acceleration, restricting the flow area of the air flow, increasing the flow velocity, and stabilizing the stability of the subsequent air flow. When inputting gas inside a single corresponding air duct, the air outlet width of the air outlet pipe 33 can cover about 1 / 3 of the spacing inside the air duct. According to Bernoulli's principle, when a negative pressure is formed at a position with a high flow velocity, the external air flow will be sucked in from about 2 / 3 of the remaining position of the compensation pipe 25 without fan input, thus forming areas with different flow velocity air flows. Therefore, by adjusting the relative position of the whole air supply mechanism 3 with respect to the front evaporator 1 of the present application, the flow velocity at different height positions inside the heat dissipation air duct can be adjusted (taking the example of Figure 8, when adjusting the left and right groups of air supply mechanisms 3, in order to achieve high-speed heat dissipation of the circulation component 14, the left air supply mechanism in the figure needs to be moved upward, and the right air supply mechanism needs to be moved downward. Conversely, when high-efficiency heat dissipation of the circulation component 15 is required, moving in the opposite direction can achieve the synchronous purpose), so that through the contact position, area, and speed of the flow velocity with the circulation pipes 12 of different heat sources, the purpose of adjusting the heat exchange efficiency can be achieved.

[0051] When adjusting, taking the case where both the circulation component 14 and the circulation component 15 have heating heat exchange requirements as an example (when there is a refrigeration requirement, the following conditions are the same), the air outlet pipe 33 is close to the circulation component with a higher temperature (i.e., a higher heat exchange requirement), which can improve the heat exchange efficiency at the position with a higher heat exchange requirement and ensure that the circulation component at the position with a lower heat exchange requirement will not be overheated, thereby neutralizing the total output heat exchange amount. To avoid the situation where, under the same wind speed, the same heat exchange efficiency wind speed is used for the circulation components with different heat exchange requirements on both sides, resulting in different upper and lower temperatures of the output air flow and further mixing being required to achieve a stable output temperature. After mixing, after calculating the specific heat capacity of the output temperature, the temperature will cause the temperature output by the circulation component at the high heating efficiency end not to be completely output to the outside, but to be mixed with the low heating efficiency end to supplement the temperature difference, thereby reducing the efficiency of the total output temperature. Therefore, the present application improves the stability of heat exchange output, reduces the working efficiency of the external heat exchanger during low-efficiency heat exchange, and ensures that the equipment can operate stably according to the external air environment.

[0052] The design solution of the present application also has control over the utilization of external temperature. For example, when a ground-source heat pump and an air-source heat pump are heating in winter, when the external air temperature is lower than the ground-source heat, the heating efficiency of the ground-source heat pump is higher than that of the air-source heat pump. And in some sunny locations or when the temperature increases during the day, the heating efficiency of the air-source heat pump will be slightly higher than that of the ground-source heat pump, or the heating efficiencies are similar. In the above cases, the air outlet 33 of the present application can successively and respectively achieve a stable heating output effect through the circulation pipe 12 close to the ground-source heat pump, the circulation pipe 12 slightly close to the air-source heat pump, or in the middle position. It is not necessary to increase the compression efficiency of the air-source heat pump to increase the temperature of the internal heat exchanger in order to achieve a stable temperature for mixed output when the heating efficiency of the ground-source heat pump is higher than that of the air-source heat pump. Therefore, a large amount of electric energy is saved and there is no need for long-term overload operation. The above example also applies to the opposite refrigeration situation. The main common point is that the air outlet pipe 33 is close to the end with a large demand for heat exchange efficiency.
