Description

Technical Field

[0001] The present application relates to the field of air conditioning technology, in particular to the field of commercial large-scale air conditioning technology, and specifically provides an outdoor unit for an air conditioner and an air conditioner. Background Art

[0002] As one of the most commonly used electrical equipment, air conditioners play a vital role in the field of air conditioning, especially in the field of large commercial air conditioners. For super-large spaces such as office buildings and hospitals, the power of conventional small household air conditioners is far from meeting the demand. It is necessary to install sufficiently large commercial air conditioners to achieve indoor air temperature regulation. This makes commercial air conditioners consume a lot of energy, and it is most urgent to improve the heat exchange efficiency. Even if the heat exchange efficiency is increased by 1%, it is a very objective energy saving in the face of such huge energy consumption, and it will also bring a significant reduction in the user's cost of use. Therefore, compared with conventional air conditioners, the need to increase the heat exchange efficiency of commercial air conditioners is more urgent.

[0003] The heat exchangers of commercial air conditioners in the existing technology are usually CV-shaped heat exchangers or V-shaped heat exchangers. Due to the structural characteristics of the heat exchanger, slight modifications have never been able to further improve the heat exchange efficiency, resulting in the high cost of air conditioners when used in large public areas, which to a certain extent limits the further development of commercial air conditioners.

[0004] Accordingly, the art requires a new outdoor unit for an air conditioner and an air conditioner to solve the above problems. Application Contents

[0005] The present application aims to solve the above technical problem, namely, to solve the problem that the heat exchange efficiency of existing commercial air conditioners still needs to be improved.

[0006] In a first aspect, the present application provides an outdoor unit for an air conditioner, the outdoor unit comprising a plurality of heat exchange units arranged in sequence, each heat exchange unit comprising a mounting bracket and a heat exchanger disposed in the mounting bracket, the heat exchanger being cylindrical.

[0007] In the above preferred technical solution for the outdoor unit of the air conditioner, the diameter D of the heat exchanger is in the range of 0.7m≤D≤1.1m.

[0008] In the above preferred technical solution for the outdoor unit of the air conditioner, the range of the distance X between the heat exchangers is 0.1m≤X≤0.5m.

[0009] In the above preferred technical solution for the outdoor unit of the air conditioner, the ratio X / D of the distance X between two adjacent heat exchangers to the diameter D of the heat exchanger is in the range of 0.25≤X / D≤0.45.

[0010] In the above preferred technical solution of the outdoor unit for an air conditioner, the diameter D of the heat exchanger and the spacing X of the heat exchangers satisfy the following formula:

[0011]

[0012] where K1 is a constant, and the value range is 1.6 ≤ K1 ≤ 4.

[0013] In the above preferred technical solution of the outdoor unit for an air conditioner, the value range of the height H of the heat exchanger is 1 m ≤ H ≤ 1.4 m.

[0014] In the above preferred technical solution of the outdoor unit for an air conditioner, the value range of the ratio H / D of the height H of the heat exchanger to the diameter D of the heat exchanger is 0.95 ≤ H / D ≤ 1.5.

[0015] In the above preferred technical solution of the outdoor unit for an air conditioner, the diameter D of the heat exchanger and the height H of the heat exchanger satisfy the following formula:

[0016] (D / 2) 2 *H = K2;

[0017] where K2 is a constant, and the value range is 0.1 ≤ K2 ≤ 0.34.

[0018] In the above preferred technical solution of the outdoor unit for an air conditioner, the rated air volume of the fan within a preset time is M, and the heat exchange air volume N of each group of the heat exchange units satisfies the following relational expression:

[0019] N = 0.72M + 0.08M / (1 + e (-(100X / 7-3)) );

[0020] where the units of M and N are m 3 / h.

[0021] On the other hand, the present application also provides an air conditioner, and the air conditioner is provided with the outdoor unit for an air conditioner described in any one of the above technical solutions.

[0022] Those skilled in the art can understand that in the technical field of the outdoor units of existing large commercial air conditioners, the heat exchangers of the outdoor units of air conditioners are usually CV-shaped or V-shaped. Such air conditioners are already relatively conventional prior arts and are only briefly described. For example, the heat exchanger inside the outdoor unit of a CV-shaped air conditioner is similar to an inverted truncated cone, and its longitudinal section is an inverted trapezoid. Another example is that the heat exchanger of a V-shaped air conditioner is similar to an inverted cone, and its longitudinal section is V-shaped. The overall heat exchange effects of these two types of air conditioners are acceptable and they have also been widely used, but there is still room for improvement in their heat exchange efficiency.

[0023] Based on this, the applicant has proposed a new outdoor unit for an air conditioner, replacing the conventional CV- or V-shaped design with a new heat exchanger. This design changes the heat exchanger to a cylindrical shape, namely a cylindrical heat exchanger with a rectangular longitudinal cross-section. Compared to heat exchangers with traditional structures, this heat exchanger has superior heat exchange efficiency. Furthermore, by combining this with the specific numerical range or formula proposed in this application, the advantages of the circular heat exchanger can be fully utilized, achieving optimal heat exchange efficiency, ultimately surpassing the original CV- or V-shaped heat exchanger and further improving the heat exchange efficiency of commercial air conditioners. Furthermore, the use of the cylindrical heat exchanger reduces the spacing between adjacent heat exchange units at optimal heat exchange efficiency, thereby reducing the overall footprint of the outdoor unit. This reduction in overall unit size also reduces production costs and reduces the amount of land required for installation.

[0024] In addition, the applicant has further defined in detail the protection range of the heat exchanger diameter D, and based on the range of the heat exchanger diameter D, detailed instructions on how to determine the values of the heat exchanger spacing X and the heat exchanger height H, thereby ensuring that the cylindrical heat exchanger of this application can exert its advantages, ensure the stability of the heat exchange efficiency, and avoid falling into an unreasonable range, which would result in the cylindrical heat exchanger being unable to replace the existing CV-shaped or V-shaped heat exchangers.

[0025] In addition, the applicant also confirmed the heat exchange air volume N of each group of heat exchange units based on the heat exchanger spacing X, thereby ensuring that the heat exchange air volume N, the rated air volume M of the fan, and the heat exchanger spacing X can be reasonably matched, effectively avoiding the waste caused by over-selection of product fans and the insufficient efficiency caused by under-selection.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] Please refer to Figures 1 to 5 , this application provides an outdoor unit for an air conditioner. The outdoor unit includes multiple groups of heat exchange units 1 arranged in sequence. Each group of heat exchange units 1 includes a mounting bracket 11 and a heat exchanger 12 arranged inside the mounting bracket 11. The heat exchanger 12 is cylindrical.

[0038] Compared with the traditional CV-shaped or V-shaped heat exchangers, this application proposes a new form of heat exchanger, the cylindrical heat exchanger 12, so that the overall product can obtain better heat exchange efficiency under the same specifications, improving the efficiency of the product. Especially for such large commercial air conditioners, after the heat exchange efficiency is improved, the cost is significantly reduced. And, compared with the CV-shaped heat exchanger or V-shaped heat exchanger, this cylindrical heat exchanger 12 is more compact as a whole, occupies less floor area, and the modular structure is easier to arrange.

[0039] The cylindrical heat exchanger 12 is different from the CV-shaped heat exchanger and the V-shaped heat exchanger. The overall structure is in a brand new state and is currently a new research and development direction. Its overall layout also has many changes. Different layouts can produce different heat exchanger energy efficiencies. Based on this, the applicant has conducted in-depth research on the outdoor unit of the new cylindrical heat exchanger 12, and has thoroughly analyzed the effects of different sizes and layouts on heat exchange.

[0040] Please refer to Figure 2 、 Figure 4 , the heat exchange unit 1 is usually sucked upward by a fan set at the top, and accordingly the air will enter the heat exchanger 12 from the side or bottom, thereby achieving heat exchange with the heat exchanger 12. In this process, Figure 4 As shown, there will be mutual airflow interference between two adjacent heat exchangers 12, and the degree of airflow interference is different at different heights. Figure 4 In the dashed box near the bottom, the wind speed is low, resulting in a low level of interference. In the dashed box near the top, due to the proximity of the fan, interference between adjacent heat exchangers 12 is high. However, different types of heat exchangers 12 have different anti-interference capabilities. The following is a study and analysis of the cylindrical heat exchanger 12 in this application.

[0041] Although in theory the farther the two are from each other, the lower the mutual interference, however, in the actual product production process, it is impossible to place the two heat exchangers too far apart. First, there are restrictions on the use site, and secondly, there are restrictions on production costs. The farther the distance, the higher the cost and the larger the installation site required, which is obviously unacceptable. If the distance is too close, the degree of mutual interference will increase and the heat exchange efficiency will decrease. Compared with traditional heat exchangers, the cylindrical heat exchanger 12 can achieve the same power product with improved heat exchange efficiency and shorter spacing. Therefore, it can be used as a preferred solution for product iteration.

[0042] See also Figure 5 The applicant conducted detailed research and experiments on four core parameters of the cylindrical heat exchanger 12 to identify a parameter combination that matches or even exceeds the performance of existing CV- and V-shaped heat exchangers. This combination of parameters enables those skilled in the art to design a more precise outdoor unit with a cylindrical heat exchanger 12, thereby achieving ideal heat exchange efficiency. The four parameters are: heat exchanger diameter D, heat exchanger spacing X, heat exchanger height H, and heat exchange air volume N of the heat exchange unit 1 (heat exchange air volume N is not a structural component and is therefore not shown in the figure).

[0043] First, let's focus on the heat exchanger diameter D. The product the applicant desires and has actually been developing is a commercial air conditioner, which is smaller than 0.7m and is classified as a small air conditioner. The difference in heat exchange efficiency between CV-shaped or V-shaped air conditioners and cylindrical air conditioners is significantly reduced in smaller areas, and this is not the applicant's research and development area. When the size is greater than 1.1m, the advantage of the higher heat exchange efficiency of the cylindrical air conditioner is also significantly reduced. Experiments have found that when the heat exchanger diameter D is between 0.7m≤D≤1.1m, the performance of the cylindrical air conditioner is better than that of the CV-shaped or V-shaped air conditioner. The applicant mainly conducts research in the range of 0.7m≤D≤1.1m, and the scope of protection is expected to be cylindrical heat exchangers within the above range.

[0044] On the basis of 0.7m≤D≤1.1m, the preferred value range of the heat exchanger spacing X is 0.1m≤X≤0.5m. Specifically, the air turbulence between the heat exchangers during air intake is not stable but nonlinear. After confirming that the size of the heat exchanger diameter D is 0.7m≤D≤1.1m, the heat exchanger spacing is selected. During the selection, it is found that as X decreases, the turbulence effect undergoes a significant mutation at X=0.1m. The turbulence influence curve soars from a relatively gentle slope σ1 to a larger value σ2, and the impact on the heat exchange efficiency of the cylindrical heat exchanger is also significantly increased. Therefore, when X≥0.1m, it is within the range of the heat exchange efficiency of the cylindrical heat exchanger recognized by the applicant. As X increases, the marginal effect begins to appear. After X=0.5m, the turbulence influence curve no longer changes from the relatively gentle slope σ3. The subsequent increase in size increases the product cost and cannot continue to significantly improve the efficiency. Therefore, the applicant's final desired protection range is 0.1m≤X≤0.5m.

[0045] Furthermore, the final value of the heat exchanger spacing X still needs to be determined based on the final value of the heat exchanger diameter D. The two are not isolated. After the heat exchanger diameter D is determined, the value range of the heat exchanger spacing X will change accordingly. The applicant has provided a corresponding relationship between the optimal ratios of the two, so that designers can accurately determine what the value range of the heat exchanger spacing X is after the heat exchanger diameter D of the designed product is determined, so that the efficiency of the heat exchanger can be improved to a level higher than that of the existing CV-shaped or V-shaped heat exchangers. Specifically, the applicant hopes to protect the ratio X / D of the spacing X between two adjacent heat exchangers to the heat exchanger diameter D, which has a value range of 0.25≤X / D≤0.5. Within this range, it can be clearly ensured that the heat exchange efficiency of the cylindrical heat exchanger 12 is higher than that of a conventional heat exchanger. Outside this range, the turbulence interference is aggravated, and at this time, it is impossible to clearly guarantee the improvement of the heat exchange efficiency.

[0046] For example, when the diameter D of the heat exchanger is selected as 1 m, the value range of X / D is 0.25 ≤ X / D ≤ 0.45. At this time, the value range of X is further restricted to 0.25 ≤ X ≤ 0.45, which is reduced compared with the range of 0.1 m ≤ X ≤ 0.5 m. That is, when the diameter D of the heat exchanger is 1 m, a better heat transfer efficiency can be obtained when the value range of X is in the smaller range of 0.25 ≤ X ≤ 0.45. Another example is that when the diameter D of the heat exchanger is selected as 0.8 m, 0.2 ≤ X ≤ 0.36. That is, when the diameter D of the heat exchanger is 0.8 m, the value range of X is further reduced compared with that when it is 1 m, and when it becomes 0.2 ≤ X ≤ 0.36, a better heat transfer efficiency can be obtained. Those skilled in the art can understand that based on the above proportional relationship to limit the interval, the applicable range of different heat exchanger spacings X based on different diameters can be more accurately delineated, and a better heat transfer efficiency can be obtained within this range.

[0047] Furthermore, the applicant also proposed a precise calculation formula for the diameter D of the heat exchanger and the heat exchanger spacing X: where K1 is a constant, and the value range is 1.6 ≤ K1 ≤ 4. More preferably, the value of K1 is 2.97, that is, the diameter D of the heat exchanger and the heat exchanger spacing X satisfy Finally, those skilled in the art can more accurately calculate the value of the most reasonable heat exchanger spacing X after confirming the final diameter D of the heat exchanger based on the above formula. For example, when D = 1.05 m, the value of K1 is 2.97, and the calculated value of X is 0.4 m, and the calculated value of X / D is 0.4.

[0048] Through the above formula, those skilled in the art can design the optimal value of X for the cylindrical heat exchanger under different diameters of the heat exchanger, so that the cylindrical heat exchanger of the present application can exert the optimal heat transfer efficiency.

[0049] The above discussion focuses on the preferred range of the heat exchanger spacing X based on 0.7m ≤ D ≤ 1.1m. In actual selection, the heat exchanger height H is also directly related to the heat exchanger diameter D. The lower the heat exchanger height H, the stronger the air suction capacity at the bottom of the heat exchanger, and the greater the probability of turbulence occurrence between them. The higher the heat exchanger height H, the worse the air suction capacity at the bottom of the heat exchanger. Although the turbulence decreases, the overall flow velocity also decreases, and complete heat exchange below cannot be achieved. Therefore, a suitable range for the heat exchanger height H should also be selected to ensure that the heat exchange efficiency of the cylindrical heat exchanger is better than that of the existing CV-shaped or V-shaped heat exchangers. After confirming that the size of the heat exchanger diameter D is within 0.7m ≤ D ≤ 1.1m, when the heat exchanger height H is less than 1m, the heat exchange area of the overall heat exchanger decreases, and the heat exchange amount cannot meet the requirements. Moreover, the state of the bottom turbulence changes from a gentle increase to a rapid intensification, resulting in serious mutual interference at the bottom, which is an inflection point where the turbulence significantly increases. After the heat exchanger height is greater than 1.4m, the bottom wind speed can no longer meet the normal heat exchange of the heat exchanger. Although turbulence is avoided, the actual efficiency of the product begins to decline rapidly, which is an inflection point where the wind speed does not meet the standard. Therefore, the ultimately desired protection range by the applicant is 1m ≤ H ≤ 1.4m.

[0050] Furthermore, the final determination of the value of the heat exchanger height H still needs to be based on the final value of the heat exchanger diameter D. The two are not isolated. After the value of the heat exchanger diameter D is determined, the range of the value of the heat exchanger height H will change accordingly. The applicant gives the corresponding relationship of the optimal ratio between the two so that designers can accurately confirm the range of the value of the heat exchanger height H when the heat exchanger diameter D of the designed product is determined, and the heat exchange efficiency of the heat exchanger can be improved to be higher than that of the existing CV-shaped or V-shaped heat exchangers. Specifically, the range of the ratio H / D of the heat exchanger height H to the heat exchanger diameter D that the applicant desires to protect is 0.95 ≤ H / D ≤ 1.5. Within this range, it can be clearly ensured that the heat exchange efficiency of the cylindrical heat exchanger is higher than that of the conventional heat exchanger. Outside this range, the turbulence interference intensifies or the bottom air volume is insufficient. Although there may still be good effects at this time, it cannot be clearly guaranteed that the heat exchange efficiency is improved compared to the traditional CV-shaped and V-shaped heat exchangers.

[0051] For example, when the heat exchanger diameter D is selected as 1m, the H / D value range is 0.95≤H / D≤1.5. At this time, the value range of the heat exchanger height H is further limited to 0.95≤H≤1.5. Since 1≤H≤1.4 is the maximum value range of H, after comprehensive comparison, the value range of H is still 1≤H≤1.4, which means that when the heat exchanger diameter D is selected as 1m, the full range of 1≤H≤1.4 can improve the heat exchange efficiency. For example, when the heat exchanger diameter D is selected to be 0.7m, the value range of the heat exchanger height H is further limited to 0.95*0.7≤H≤1.5*0.7, that is, 0.665≤H≤1.05. Combined with the maximum value range of H of 1≤H≤1.4, the final value range of H is 1≤H≤1.05, which means that when the heat exchanger diameter D is selected to be 0.7m, the heat exchange efficiency can be improved within the range of 1≤H≤1.05. For example, when the heat exchanger diameter D is 1.1m, the range of heat exchanger height H is further limited to 0.95*1.1≤H≤1.5*1.1, that is, 1.045≤H≤1.65. Combined with the maximum range of H of 1≤H≤1.4, the final range of H is 1.045≤H≤1.4. This means that when the heat exchanger diameter D is 1.1m, the heat exchange efficiency can be improved within the range of 1.045≤H≤1.05. Those skilled in the art will understand that by limiting the range based on the above proportional relationship, the applicable range of different heat exchanger heights H based on different heat exchanger diameters D can be more accurately delineated based on different diameters.

[0052] Furthermore, the applicant has proposed a precise calculation formula for the heat exchanger diameter D and the heat exchanger height H: (D / 2) 2 *H=K2. K2 is a constant with a value range of 0.1≤K2≤0.34. More preferably, the value of K2 is 0.324, that is, the heat exchanger diameter D and the heat exchanger height H satisfy (D / 2) 2 *H = 0.324. Ultimately, those skilled in the art can use the above formula to more accurately calculate the optimal heat exchanger height after the final heat exchanger diameter D is confirmed. For example, when D = 1.05m, K2 is 0.324, the corresponding H is calculated to be 1.176m, and the H / D ratio is 1.12.

[0053] Through the above formula, those skilled in the art can design the optimal H value of the cylindrical heat exchanger under different heat exchanger diameters, so that the cylindrical heat exchanger of the present application can achieve the optimal heat exchange efficiency.

[0054] The above has respectively given a detailed explanation of the values among the heat exchanger spacing X, the heat exchanger height H, and the heat exchanger diameter D. Further, the heat exchange air volume N of each heat exchange unit 1 also directly affects the total heat exchange amount and the heat exchange efficiency of the heat exchanger. Through research, it is known that in terms of the correlation strength of the cylindrical heat exchanger in this application, the heat exchange air volume N has a closer relative relationship with the heat exchanger spacing X rather than the heat exchanger diameter D. Therefore, this application mainly uses the heat exchanger spacing X as a reference to confirm the heat exchange air volume N.

[0055] The heat exchange air volume N of each said heat exchange unit 1 satisfies the following relational expression:

[0056] N = 0.72M + 0.08M / (1 + e (-(100X / 7-3)) );

[0057] wherein, M is the rated air volume of the fan within a preset time, and the units of M and N are m 3 / h, and the unit of X is m.

[0058] For example, when the fan with M value of 25000 is used, the formula at this time is N = 18000 + 2000 / (1 + e (-(100X / 7-3)) ). After calculation, the value of the heat exchange air volume N obtained is between 18000 - 20000, and it varies with the different heat exchanger spacings X. Those skilled in the art can design different X values according to the requirements of different heat exchange air volume N values, thereby meeting the requirements of the optimal heat exchange air volume, avoiding the situation where the product power design does not match the heat exchanger spacing X, that is, avoiding the situation of over-performance or under-performance of the product design.

[0059] To sum up, this application not only provides a new outdoor unit of the cylindrical heat exchanger 12, but also designs the relevant ranges, ratios, and formulas of the heat exchanger diameter D, the heat exchanger spacing X, the heat exchanger height H, and the heat exchange air volume N that can exert its optimal effect based on this special structure. Based on the above limitations, the solution of the cylindrical heat exchanger 12 in this application can exceed the heat exchange efficiency of the CV-shaped heat exchanger or the V-shaped heat exchanger, enable the outdoor unit of the cylindrical heat exchanger 12 to exert its advantages, avoid its inferiority interval, and make the product truly become one of the mainstream heat exchangers in the market in the future.

[0060] It should be noted that the above embodiments are only used to illustrate the principle of the present invention and are not intended to limit the protection scope of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0061] For example, in an alternative embodiment, the number of the heat exchange units 1 can be adjusted arbitrarily, such as two, three, six, etc. As long as it can be applied to the outdoor unit of the cylindrical heat exchanger in the value range mentioned in the present application, it will fall within the protection scope of the present invention.

[0062] In addition, the present invention also provides an air conditioner, which has the outdoor unit for the air conditioner described in any one of the above embodiments.
