[0002] HVAC involves people's livelihood and is an engineering technology that the country attaches great importance to. HVAC equipment usually requires a mounting frame for fixed installation. Due to its own operation, HVAC equipment is usually accompanied by vibration and noise. This is an unavoidable problem in industrial design. Therefore, in addition to the function of installing and fixing HVAC equipment, the mounting frame of HVAC equipment also needs to provide noise reduction and vibration reduction. For example, a HVAC equipment noise reduction mounting frame recorded in the patent announcement number CN212719029U, the device installs an air bag inside the base. After the air bag is compressed, the air bag will spit out gas to give an upward force. The device can effectively prevent the HVAC equipment from moving downward, but does not limit the upward movement of the equipment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0023] Example 1
[0024] See also Figure 1-4 A noise reduction mounting frame for HVAC equipment. When in use, a fixing frame 100 is installed on the periphery of the HVAC equipment. A plurality of fixing frames 100 are arranged in an array vertically to the ground. The size of the fixing frame 100 is manufactured according to the size of the HVAC equipment, and the HVAC equipment can be completely fixed. The fixing frame 100 is connected to a reinforcement structure. The reinforcement structure includes a reinforcement frame 201, a reinforcement hole 202, a reinforcement rod 203 and a mounting hole 204. The reinforcement frame 201 is fixedly connected to the plurality of fixing frames 100 to provide pressure for the reinforcement frame 201, thereby improving the fixing ability of the reinforcement frame 201 to the HVAC equipment. The four reinforcement frames The cylindrical array 201 is distributed around the reinforcement frame 201, and the reinforcement rod 203 is installed at the diagonal position of the reinforcement frame 201. The reinforcement frame 201 is a quadrilateral structure with insufficient stability. The reinforcement rod 203 can improve the stability of the reinforcement frame 201. A reinforcement hole 202 is provided on the side of the reinforcement frame 201 away from the fixed frame 100. The reinforcement hole 202 connects the sound insulation structure and the reinforcement frame 201. The mounting hole 204 is provided on the lower surface of the reinforcement frame 201 and contacts the ground. The mounting hole 204 fixes the reinforcement frame 201 to the ground. The sound insulation structure can isolate the propagation of sound and noise.
[0025] The sound insulation structure includes a sound insulation board 301, a fixer 302 and a fixing screw hole 303. The sound insulation board 301 is provided with a hole position corresponding to the reinforcement hole 202. The sound insulation board 301 is fixedly connected to the reinforcement frame 201 through the reinforcement hole 202. There are four sound insulation boards 301 in total. Fixers 302 are respectively provided at the four corners of the four sound insulation boards 301. The fixers 302 are fixedly connected to the sound insulation boards 301. A fixing screw hole 303 is provided in the middle of the fixer 302. The fixer 302 and the fixing screw hole 303 fix the sound insulation board 301 to the ground.
[0026] One of the sound insulation panels 301 is provided with a circular hole, which allows the pipes of the heating and ventilation equipment to be normally connected to the terminal.
[0027] A buffer structure is provided below the fixed frame 100, and the buffer structure includes a cavity base 401, a sliding support block 402, an auxiliary support column 403 and an inner cavity 404. The cavity base is below the HVAC equipment. The cavity base 401 is provided with an inner cavity 404. A sliding support block 402 is slidably provided on the inner wall of the inner cavity 404. The auxiliary support column 403 is also slidably arranged on the inner wall of the inner cavity 404. The auxiliary support column 403 is distributed in a circular array around the sliding support block 402. Multiple auxiliary support columns 403 and the sliding support block 402 support the HVAC equipment at the same time. The sliding support block 402 is fixedly connected to the HVAC equipment. When the HVAC equipment vibrates during operation, the sliding support block 402 can prevent the heating equipment from vibrating. The base 401 is fixed to the ground to fix the position of the entire heating equipment. The internal space of the cavity base 401 forms an air bag 500. The air pressure of the air bag 500 is consistent with the external air pressure. When an external force acts on the air bag 500 and causes a change, the air pressure will prevent the volume of the air bag 500 from changing, thereby offsetting the external force.
[0028] Example 2
[0029] The airbag 500 is filled with an inert gas, and the inert gas is an inert gas with high stability.
[0030] The connection positions between the four sound insulation panels 301 are provided with sound insulation cotton seals, which can increase the sound insulation capacity of the sound insulation structure.
[0031] The fixing frame 100 and the reinforcement frame 201 are made of aluminum alloy. Aluminum alloy has high hardness and is corrosion-resistant, so the HVAC equipment noise reduction mounting frame can have a longer service life.
[0032] During installation, the base 401 is fixed to the ground, the positions of the auxiliary support columns 403 and the sliding support block 402 are fixed at the same time, the HVAC equipment is installed on the upper surface of the sliding support block 402 and fixedly connected, and the four fixing frames 100 are sequentially installed on the periphery of the HVAC equipment to limit the position of the HVAC equipment. The reinforcement frame 201 is fixedly installed with the fixing frame 100 to increase the fixing effect of the fixing frame 100 on the HVAC equipment. Reinforcement rods 203 are installed on the diagonal line of the reinforcement frame 201 to enhance the stability of the reinforcement frame 201. The reinforcement frame and the sound insulation board 301 are connected at corresponding positions through the reinforcement holes 202, and the sound insulation board 301 is fixed to the ground under the action of the fixer 302 and the fixing screw hole 303.
[0033] When working, the HVAC equipment emits vibration and noise. The noise is blocked by the sound insulation board 301 during propagation, and the front, rear, left and right vibrations are limited by the fixed frame 100, the reinforcement frame 201 and the reinforcement rod 203, so the vibration amplitude is reduced. The up and down vibration drives the sliding support block 402 to vibrate, and the volume of the airbag 500 changes. A pressure difference is generated between the airbag 500 and the external air pressure, and the generated air pressure is used to offset the pressure difference, thereby reducing the up and down vibration amplitude of the HVAC equipment.
[0034] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
