Detailed Description
Referring to fig. 1 to 2, the invention relates to a transverse low-noise wall-mounted air-source heat pump all-in-one machine, which comprises a box body 1 and an air supply system, wherein a compressor 2 is installed on the front side part in the box body 1, an evaporator is installed on the rear side part in the box body 1, and the compressor 2, the evaporator and the like are installed at the end part of an inner cylinder of a water heater through installation support plates. The air supply system comprises an air inlet 5 and a plurality of centrifugal fans 4. The air inlet 5 is arranged at the rear side of the box body 1, and the evaporator is arranged close to the air inlet 5.
In order to increase the volume of the evaporator, the evaporator is made in an arc shape and is arranged basically adjacent to the inner wall of the box body 1. Specifically, the evaporator can be the arc form for the integral type shaping, or form the arc form by the end to end connection of a plurality of evaporator unit 3, and every evaporator unit 3 is rectangular shape. A plurality of centrifugal fans 4 arranged in an arc shape are arranged along the inner arc surface of the evaporator, and an air outlet 6 of each centrifugal fan 4 is arranged to point to the end part of the box body 1 along the axial direction of the box body 1 or is arranged to point to the circumference of the box body 1 along the radial direction of the box body 1. The centrifugal fan 4 works, airflow enters through the air inlet 5 and then passes through the evaporator, the accelerated airflow improves the heat exchange efficiency, and the airflow flows out through the air outlet 6 again. The air outlet 6 is flexibly and changeably arranged, and smooth air flow guiding-out can be realized no matter the air outlet is arranged at the end part of the box body 1 axially pointing to the box body 1 or arranged at the circumference of the box body 1 radially pointing to the box body 1.
In the invention, the evaporator is designed into an arc shape, which is beneficial to increasing the design volume of the evaporator, thereby enhancing the heat exchange capacity of the evaporator and realizing the improvement of the overall performance of the heat pump all-in-one machine. Meanwhile, the centrifugal fan 4 is adopted in the air supply system, and the air inlet and outlet mode is designed to be opposite to that of the prior art, so that the air resistance of an air duct is reduced, the air inlet and outlet area is increased, the unit can obtain increased air volume under the condition of low air speed, the noise of a fan module is reduced, and the performance of the whole machine is improved. On the other hand, because the noise of centrifugal fan 4 itself is less to this air supply system's air inlet and air-out all need not to pass through compressor 2, have effectively avoided compressor 2 noise to follow the air current and together are spread.
Specifically, the evaporator may include three evaporator units 3 connected end to end, and the number of the centrifugal fans 4 is equal to the number of the evaporator units 3 and is respectively fixedly disposed on the inner side surfaces of the evaporator units 3; and the air outlet 6 can be designed adaptively in advance according to the installation space of the heat pump all-in-one machine on site.
An air outlet 6 of the centrifugal fan 4 positioned at the upper part is obliquely arranged upwards, and the air outlet 6 penetrates through the periphery of the box body 1 and points to the upper front part of the box body 1; an air outlet 6 of the centrifugal fan 4 positioned at the lower part is obliquely arranged downwards, and the air outlet 6 penetrates through the periphery of the box body 1 and points to the lower front part of the box body 1; an air outlet 6 of the centrifugal fan 4 positioned in the middle is horizontally arranged along the axial direction of the box body 1, and the air outlet 6 penetrates through the end part of the box body 1. In order to avoid backflow of cold air, an air guide angle 7 is arranged on the periphery of the box body 1, and the air guide angle 7 is located above the rear side of the air outlet 6 and inclines towards the front side of the box body 1. When cold air flows out of the air outlet 6, the cold air always flows towards the front end of the box body 1 under the action of the air guide angle 7, and the cold air is prevented from entering the air inlet 5 again, so that the heat exchange efficiency is further influenced.
Or the evaporator is arranged to comprise three evaporator units 3 connected end to end, the number of the centrifugal fans 4 is equal to that of the evaporator units 3, and the centrifugal fans are respectively and fixedly arranged on the inner side surfaces of the evaporator units 3; the air outlets 6 of the three centrifugal fans 4 are all horizontally arranged along the axial direction of the box body 1 and all penetrate through the end part of the box body 1. The outlet 6 may adopt this design in the case where the upper and lower spaces of the cabinet 1 are limited but the installation space of the end of the cabinet 1 is abundant.
Meanwhile, the evaporator may be further designed to include two evaporator units 3 connected end to end, and the number of the centrifugal fans 4 is two and is respectively fixedly disposed on the inner side surfaces of the evaporator units 3. The number of evaporator units 3 can be determined in particular according to the power of the complete machine.
For the situation that the installation space at the two ends of the box body 1 is not enough, the air outlet 6 of the centrifugal fan 4 positioned at the upper part can be obliquely arranged upwards, the air outlet 6 penetrates through the periphery of the box body 1 and points to the upper front part of the box body 1, the air outlet 6 of the centrifugal fan 4 positioned at the lower part is obliquely arranged downwards, and the air outlet 6 penetrates through the periphery of the box body 1 and points to the lower front part of the box body 1; the air flow is prevented from quickly impacting the wall and flowing back after flowing out from the two ends of the box body 1.
Or, the air outlets 6 of the two centrifugal fans 4 can be horizontally arranged along the axial direction of the box body 1 and penetrate through the end part of the box body 1. The arrangement mode can meet the condition that the mounting space above and below the box body 1 is insufficient but the mounting space at the end part of the box body 1 is sufficient.
Preferably, a partition plate 8 is arranged in the box body 1 and positioned between the compressor 2 and the evaporator, and the partition plate 8 and the inner wall of the box body 1 form a closed sound insulation cavity for insulating noise of the compressor 2. The noise that compressor 2 sent has realized effectively completely cutting off under the effect in airtight sound insulation chamber, avoids this heat pump all-in-one to send great noise in the use. Meanwhile, the centrifugal fans 4 can also be arranged on the partition plate 8, and gaps are reserved among all the centrifugal fans 4 to prevent air volume interference.
The air supply system of the transverse low-noise wall-mounted air-source heat pump all-in-one machine can provide a uniform air field, so that an evaporator can exchange heat uniformly, and meanwhile, the air field is low in resistance and low in noise. The evaporator can realize the increase of the volume, and the overall performance of the heat pump all-in-one machine is improved.
While the embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
