Description

Technical Field

[0001] The utility model belongs to the technical field of air source heat pumps, and in particular relates to an air source heat pump structure for preventing cold island effect. Background Art

[0002] An air source heat pump is an energy-saving device that uses air as a heat source and absorbs and utilizes the heat energy in the air through a working fluid. It consists of four parts: an evaporator, a compressor, a condenser, and an expansion valve. It is a heat energy utilization system with relatively high energy efficiency.

[0003] During operation, the air source heat pump absorbs the heat of the surrounding air and outputs energy from the heat pump to provide heating to the end user. When installing, the air source heat pump is usually placed in an outdoor ventilated area. However, sometimes the air source heat pump is not allowed to be placed in an outdoor ventilated area, so sometimes the air source heat pump is placed in a poorly ventilated place. As the air source heat pump runs, the surrounding air temperature continues to decrease. Due to the lack of external air supplementation and replacement, the temperature of the air around the air source heat pump is lower than the normal air temperature, thus forming a cold island effect. In addition, when multiple heat exchange units are operated together, due to space limitations, when multiple hosts are running at the same time, especially when the wind speed is low or there is no wind, a cold island effect will occur in the host group layout area, causing the heat exchange efficiency to be greatly reduced.

[0004] Therefore, it is urgent to design an air source heat pump structure that prevents the cold island effect to solve the problem mentioned above that the temperature of the air around the air source heat pump is lower than the normal air temperature, thereby forming a cold island effect and reducing the heat exchange efficiency of the air source heat pump. Utility Model Content

[0006] To achieve the above objectives, the specific technical solution of the air source heat pump structure for preventing the cold island effect of the utility model is as follows:

[0008] Furthermore, the spoiler assembly includes a plurality of V-shaped spoiler structures, and the plurality of V-shaped spoiler structures are sequentially arranged at intervals along the first direction, and each V-shaped spoiler structure is overlapped and arranged between two adjacent evaporators.

[0009] Furthermore, the V-shaped spoiler structure includes a first spoiler and a second spoiler, one end of the first spoiler is connected to one end of the second spoiler, the other end of the first spoiler abuts against the top edge of an evaporator, and the other end of the second spoiler abuts against the top edge of an adjacent evaporator.

[0010] Furthermore, one end where the first spoiler is connected to the second spoiler is hinged to adjust the angle between the first spoiler and the second spoiler.

[0011] Furthermore, the V-shaped spoiler structure also includes a connecting plate, which is vertically arranged with the V-shaped spoiler structure, and the connecting plate connects and fixes the multiple V-shaped spoiler structures in sequence.

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0028] Please refer to the attached Figure 1 To Attachment Figure 5 The utility model describes an air source heat pump structure for preventing the cold island effect.

[0029] like Figure 1As shown, multiple air source heat pump units are connected in parallel, and multiple air source heat pumps are arranged in a matrix form, which is an important heating method for centralized heating. At low wind speeds, the density of the cold air discharged from evaporator 1 is greater than that of the ambient air, and it cannot be effectively mixed with the ambient air. The cold air will sink, and the sinking cold air will enter the evaporator 1 from the inlet of evaporator 1 for heat exchange. Under normal circumstances, the air inhaled at the inlet of evaporator 1 is ambient air. After the ambient air undergoes heat exchange in evaporator 1, the cold air is discharged from fan 2. However, when the cold air is inhaled at the inlet of evaporator 1 for heat exchange, the cold air is lower than the ambient air temperature, which will cause the air temperature inside evaporator 1 to drop, forming a cold island effect, which affects the heat exchange efficiency of the air source heat pump. The direction of the cold air flow is as shown in the figure. Figure 1 Therefore, after the cold air sinks, it is necessary to block the cold air to prevent the cold air from entering the evaporator 1 for heat exchange. Therefore, it is urgent to design an air source heat pump structure that prevents the cold island effect to solve the above-mentioned problems.

[0030] like Figures 1 to 5 As shown, the air source heat pump structure for preventing the cold island effect in the utility model includes a plurality of air source heat pumps, and the plurality of air source heat pumps are arranged in a matrix form. An evaporator 1 is provided in each air source heat pump, and a fan 2 is connected to the top of the evaporator 1. A spoiler component 3 is also included, and the spoiler component 3 is overlapped at the edge position of the top of two adjacent evaporators 1, and the cold air flowing out of the fan 2 is directed upward through the spoiler component 3.

[0031] A plurality of air source heat pumps are arranged in a matrix form, and an evaporator 1 is provided in each air source heat pump. A fan 2 is connected to the top of the evaporator 1. A spoiler component 3 is provided, and the spoiler component 3 is overlapped at the edge position of the top of two adjacent evaporators 1. The cold air flowing out of the fan 2 is guided upward through the spoiler component 3, thereby preventing the cold air discharged from the evaporator 1 from having a density greater than that of the ambient air, failing to effectively mix with the ambient air, and sinking back to the inlet of the evaporator 1 for heat exchange, thereby reducing the local air temperature inside the unit. By providing the spoiler component 3, the cold island effect is avoided and the heat exchange efficiency of the air source heat pump is improved.

[0032] Further, if Figures 1 to 5 As shown, the spoiler assembly 3 includes a plurality of V-shaped spoiler structures 31, which are arranged in sequence along the first direction, and each V-shaped spoiler structure 31 is overlapped and arranged between two adjacent evaporators 1. The V-shaped spoiler structure 31 includes a first spoiler plate 311 and a second spoiler plate 312, one end of the first spoiler plate 311 is connected to one end of the second spoiler plate 312, the other end of the first spoiler plate 311 abuts against the top edge of one evaporator 1, and the other end of the second spoiler plate 312 abuts against the top edge of the adjacent evaporator 1. In this embodiment, the first direction is Figure 2The direction shown by L1.

[0033] By setting a plurality of V-shaped spoiler structures 31, the plurality of V-shaped spoiler structures 31 are overlapped at intervals between two adjacent evaporators 1, that is, a V-shaped spoiler structure 31 is set between every two evaporators 1, and the upper and lower parts of the two evaporators 1 are separated. The cold air coming out of the fan 2 after the heat exchange in the evaporator 1 will only move upward along the first spoiler plate 311 or the second spoiler plate 312 under the blocking of the V-shaped spoiler structure 31, and will not move downward to enter the entrance of the evaporator 1. The V-shaped spoiler structure 31 blocks the cold air and avoids the cold island effect. The V-shaped spoiler structure 31 blocks the cold air. Figure 4 Direction indicated by the arrow.

[0034] Further, if Figures 1 to 5 As shown, in the actual working process, when multiple air source heat pumps are arranged in a matrix form, the spacing distance between two adjacent air source heat pumps arranged along the first direction is different, that is, the spacing distance between two adjacent evaporators 1 is different. In order to better adapt to the different distances between two adjacent evaporators 1, in this embodiment, one end of the first spoiler 311 and the second spoiler 312 is hinged to adjust the angle between the first spoiler 311 and the second spoiler 312. When the distance between two adjacent evaporators 1 changes, it is only necessary to adjust the angle between the first spoiler 311 and the second spoiler 312, so that the V-shaped spoiler structure 31 can be overlapped between adjacent evaporators 1 at different distances. In this embodiment, a damping structure is provided at the hinge between the first spoiler 311 and the second spoiler 312, and the angle between the first spoiler 311 and the second spoiler 312 can be adjusted at will. After the angle between the first spoiler 311 and the second spoiler 312 is adjusted, the first spoiler 311 is overlapped on the top edge of one evaporator 1, and the other spoiler is overlapped on the top edge of another adjacent evaporator 1.

[0035] Further, if Figures 1 to 5 As shown, in order to connect multiple V-shaped spoiler structures 31 together and facilitate overlapping multiple V-shaped spoilers on the evaporator 1 arranged in a matrix form, the V-shaped spoiler structure 31 also includes a connecting plate 32, which is arranged vertically with the V-shaped spoiler structure 31, and the connecting plate 32 connects and fixes the multiple V-shaped spoiler structures 31 in sequence. Through holes are provided on the multiple V-shaped spoiler structures 31, and the connecting plate 32 passes through the multiple through holes in sequence to connect and fix the multiple V-shaped spoiler structures 31. In other embodiments, the connecting plate 32 can also be set at the top of the V-shaped spoiler structure 31 to connect the multiple V-shaped spoiler structures 31, and can also be set at other positions of the V-shaped spoiler structure 31, as long as the V-shaped spoiler structures 31 can be connected together.

[0036] Further, if Figures 1 to 5 As shown, in order to increase the stability of the connection, in this embodiment, a plurality of connecting plates 32 are provided, and the plurality of connecting plates 32 are sequentially spaced and arranged along the second direction to connect and fix the plurality of V-shaped spoiler structures 31, and each connecting plate 32 is arranged above two adjacent evaporators 1. The plurality of connecting plates 32 are provided, on the one hand, to connect the plurality of V-shaped spoiler structures 31 and increase the stability of the connection; on the other hand, the connecting plates 32 are provided between adjacent evaporators 1 arranged along the second direction to play a role in blocking cold air. In this embodiment, the second direction is Figure 2 The direction shown by L2.

[0037] Further, if Figures 1 to 5 As shown, in the actual working process, when multiple air source heat pumps are arranged in a matrix form, the spacing distance between two adjacent air source heat pumps arranged along the second direction is different, that is, the spacing distance between two adjacent evaporators 1 is different. In order to better adapt to the different distances between two adjacent evaporators 1, in this embodiment, multiple connecting plates 32 are all slidably set on the V-shaped spoiler structure 31 along the second direction, and the connecting plates 32 are slidably set on the V-shaped spoiler structure 31 to adjust the position of the connecting plates 32 on the V-shaped spoiler structure 31 to better adapt to the different distances between two adjacent evaporators 1. In this embodiment, as Figure 5 As shown, the width of the connecting plate 32 is greater than the distance between two adjacent evaporators 1 arranged along the second direction.

[0038] Further, if Figures 1 to 5 As shown, in this embodiment, in order to facilitate the overlapping of the spoiler assembly 3 on the evaporators 1 arranged in a matrix and ensure the stability of the V-shaped spoiler structure 31, the spoiler assembly 3 and the multiple evaporators 1 are screwed or snap-fixed. In other embodiments, the spoiler assembly 3 and the evaporator 1 can also be connected and fixed by other structures as long as a stable connection interface between the spoiler assembly 3 and the evaporator 1 can be guaranteed.

[0039] The use process of the air source heat pump structure for preventing the cold island effect of the utility model is as follows:

[0040] According to the spacing between the multiple air source heat pumps arranged in a matrix, that is, according to the spacing between the multiple evaporators 1 arranged in a matrix, the spacing between two adjacent evaporators 1 arranged along the first direction, the angle between the first spoiler 311 and the second spoiler 312 is adjusted, so that the V-shaped spoiler structure 31 is adapted to the spacing between the two adjacent evaporators 1, so that the V-shaped spoiler is overlapped between the two adjacent evaporators 1, that is, the first spoiler 311 is overlapped at the edge position of the top of one evaporator 1, and the second spoiler 312 is overlapped at the edge position of the top of another evaporator 1. The V-shaped spoiler is used to inhibit the cold air from the fan 2 from flowing downward, and the upper cold air and the lower air are blocked to prevent the cold air from flowing downward into the evaporator 1. According to the spacing between the two adjacent evaporators 1 arranged along the second direction, the position of the connecting plate 32 on the V-shaped spoiler structure 31 is adjusted, and the connecting plate 32 is adjusted above the two adjacent evaporators 1 to play a role in blocking the cold air. The cold air is blocked by the V-shaped spoiler structure 31 and the connecting plate 32 to prevent the cold air from flowing back into the evaporator 1, thereby effectively suppressing the cold island effect.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
