Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology for heat pump units, and in particular to a noise reduction room for air-cooled heat pump units. Background Technology

[0002] Air-cooled heat pump units are high-efficiency air conditioning, heating, and cooling equipment, widely used in shopping malls, office buildings, hospitals, stadiums, exhibition halls, and other places with centralized heating and cooling needs. When operating, air-cooled heat pump units generate vibration and airflow noise from their compressors and pumps, producing significant noise that can disturb the surrounding environment. This is particularly true when installed in residential areas, office areas, and other living and working areas, often leading to noise complaints.

[0003] Existing air-cooled heat pump units also have some noise reduction facilities or methods, such as installing sound-absorbing barriers around the sides of the unit, but exhausting and dissipating heat on the top. These facilities are simple to install and relatively low in cost, but their noise reduction effect is generally limited. Another example is the Chinese invention patent application CN202310194051.1, entitled "A Noise Reduction Device for an Air-Cooled Heat Pump Unit," which uses a sound-insulating and sound-absorbing enclosure to minimize noise emissions. However, it is installed in a ground-level machine room, and the sound insulation and noise reduction effect of the soundproof walls is generally limited, which can negatively impact the landscape. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a noise reduction room for an air-cooled heat pump unit, which adopts a sunken ground layout, has good sound insulation and noise reduction effect, and has little impact on the landscape layout.

[0005] This utility model is achieved using the following technical solution: a noise reduction room for an air-cooled heat pump unit, comprising a main body of the room, an opening, an air inlet channel, an air outlet channel, a unit platform, an air inlet silencer, an air outlet silencer, a fan, and a mounting cover. The main body of the room is recessed into the ground, with its top end level with the ground. The unit platform is horizontally positioned on the ground of the main body of the room. An opening is provided at the top of the main body of the room, and a mounting cover is provided over the opening. An air inlet channel is vertically arranged at one end of the main body of the room, and an air outlet channel is vertically arranged at the other end of the main body of the room. The heat pump unit is fixedly installed on the unit platform. An air inlet silencer is installed in the air inlet channel, and an air outlet silencer is installed in the air outlet channel. The fan is also fixed in the air outlet channel, located below the air outlet silencer.

[0006] Furthermore, the inner walls and top of the main body of the computer room are covered with a layer of noise reduction board.

[0007] Furthermore, an inspection port is provided at the top of the main body of the computer room, and an inspection cover plate is provided on the inspection port. A row of ladders is provided on the inner wall of the main body of the computer room below the inspection port.

[0008] Furthermore, noise reduction plates are provided at the bottom of both the installation cover plate and the maintenance cover plate.

[0009] Furthermore, an air intake shield is provided above the air intake duct, and an exhaust shield is provided above the exhaust duct.

[0010] Furthermore, a drainage trough is provided at the top of the main body of the computer room, on the outer ring of the mounting cover plate.

[0011] Furthermore, the upper end of the mounting cover is provided with several mounting cover lifting rings.

[0012] Compared to existing technologies, the advantages of this utility model are as follows: The noise reduction room for an air-cooled heat pump unit is a sunken floor-mounted design, minimizing its impact on the landscape. During use, external air enters through the air intake duct and exits through the exhaust duct, achieving air convection and heat dissipation within the room. Silencers within the air intake and exhaust ducts reduce noise in the airflow. Noise-reducing plates on the inner walls, top, and bottom of the cover plate of the room reduce noise at openings and access panels. This results in excellent sound insulation and noise reduction for the air-cooled heat pump unit noise reduction room, effectively minimizing noise interference to the surrounding area.

[0016] The purpose of this invention is to address the shortcomings of existing technologies by providing a noise reduction system for air-cooled heat pump units.

[0017] Example 1

[0018] This embodiment provides a noise reduction room for an air-cooled heat pump unit, referring to... Figure 1 As shown, the system includes a main computer room 11, an opening 12, an air intake duct 13, an exhaust duct 14, a unit platform 15, an air intake silencer 21, an exhaust silencer 22, a fan 24, and a mounting cover 31. The main computer room 11 is a sunken floor-mounted structure, with its top level with the ground. The unit platform 15 is horizontally positioned on the floor inside the main computer room 11. The top of the main computer room 11 has an opening 12, which is covered by the mounting cover 31. The unit platform 15 is located within the opening. Below 12, an air inlet duct 13 is vertically installed at one end of the main body 11 of the computer room, and an exhaust duct 14 is vertically installed at the other end of the main body 11. The heat pump unit 10 is fixedly installed on the unit platform 15. An air inlet silencer 21 is installed in the air inlet duct 13, and an exhaust silencer 22 is installed in the exhaust duct 14. The air inlet silencer 21 and the exhaust silencer 22 in this embodiment use existing pipe silencers, so that the sound energy is dissipated by friction in the pores of the porous material in the pipe. The fan 24 is also fixed in the exhaust duct 14, and the fan 24 is located below the exhaust silencer 22. In this embodiment, the fan 24 uses an existing industrial axial flow fan to improve air convection in the main body 11 of the computer room and to achieve heat dissipation.

[0019] Reference Figure 1 As shown, an access panel 41 is provided at the top of the main body 11 of the computer room. An access panel 42 is provided on the access panel 41 and can be opened and closed. A row of ladders 43 is located on the inner wall of the main body 11 below the access panel 41. The ladders 43 can be existing ladders with steel cages to improve safety. Maintenance personnel can open the access panel 42 and enter the main body 11 through the ladders during regular inspections or maintenance. An air intake shield 16 is provided above the air intake duct 13, and an exhaust shield 17 is provided above the exhaust duct 14 to prevent external rainwater from entering the main body 11 along the air ducts. A drainage channel 18 is provided at the top of the main body 11, around the outer edge of the cover 31, for convenient drainage.

[0020] Reference Figure 1 As shown, the inner walls and top of the main body 11 of the computer room are covered with a layer of noise reduction board 23 to further reduce noise around the main body 11 of the computer room. Noise reduction boards 33 are provided at the bottom of the mounting cover 31 and the maintenance cover 42. In this embodiment, the noise reduction board 23 and the cover noise reduction board 33 can use existing ceramic aluminum sound-absorbing panels or microporous noise reduction panels to reduce noise at openings and maintenance ports. Several mounting cover lifting rings 32 are provided at the upper end of the mounting cover 31 to facilitate opening the mounting cover 31 when installing the heat pump unit 10.

[0021] This utility model discloses a noise reduction room for an air-cooled heat pump unit. The main body 11 of the room is sunken into the ground, minimizing its impact on the landscape. During installation, the mounting cover 31 is opened, and the heat pump unit 10 is hoisted into the main body 11 and installed on the unit platform 15. In use, the fan 24 in the exhaust duct 14 operates to exhaust air, allowing outside air to enter through the air inlet duct 13 and exit through the exhaust duct 14, achieving air convection and heat dissipation within the main body 11. Silencers installed in the air inlet duct 13 and exhaust duct 14 reduce noise in the air ducts. Noise-reducing plates installed on the inner walls, top, and bottom of the cover of the main body 11 reduce noise at openings and access panels, resulting in a soundproof and noise-reducing room for the air-cooled heat pump unit, effectively reducing noise interference to the surrounding area.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
