Description

Technical Field

[0001] The utility model relates to the technical field of air energy heat pumps, in particular to a noise reduction shell of an air energy heat pump. Background Art

[0002] Air energy heat pump is a highly efficient heating and hot water supply equipment, and its working principle is mainly based on the "reverse Carnot" effect and the second law of thermodynamics. The working mode of air energy heat pump is different from that of traditional water heaters or air conditioning systems. It does not generate heat by burning fuel, but by absorbing free heat energy in the environment (such as heat in the air) and efficiently converting this part of heat energy into comfortable living energy. This method not only saves energy, but also helps to reduce environmental pollution. The working principle of air energy heat pump can be summarized as follows: Energy conversion: by absorbing low-grade heat energy from the external environment, such as heat in the air, it is converted into high-grade heat energy for people to use; Thermodynamic cycle: using the reverse Carnot cycle principle, through the cooperation of evaporator, compressor, condenser, complete the transfer and circulation of energy; Energy saving and environmental protection: compared with traditional coal-fired boilers, air energy heat pump is more energy-saving and environmentally friendly because it does not produce carbon dioxide emissions; Automatic control: modern air energy heat pumps are usually equipped with automatic control systems, which can automatically adjust the working state according to needs to achieve the best energy efficiency ratio.

[0003] When the air-energy heat pump is actually used, the compressor inside it needs to compress all the time, which causes the compressor to generate large vibrations and noises when in use, thereby causing noise interference to nearby residents when the air-energy heat pump is in use. A noise reduction shell of the air-energy heat pump is needed, but the existing noise reduction shell and the air-energy heat pump are an integrated structure, which is not convenient for disassembly and installation, resulting in difficult maintenance work. Therefore, a noise reduction shell of an air-energy heat pump that is easy to install is needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a noise reduction housing of an air energy heat pump which is easy to install.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a noise reduction shell of an air-energy heat pump, comprising a first support plate and a heat pump body, a second support plate being connected to the top of the first support plate, the heat pump body being fixedly arranged at the center of the top surface of the second support plate, a shell body being arranged around the heat pump body on the top surface of the second support plate, a mounting plate being fixedly arranged at the top end of the outer wall of the shell body on the top end of the second support plate, a plurality of damping shock absorbers being evenly embedded on the top surface of the second support plate and being screwed together with the mounting plate, and a sound absorbing panel being fixedly arranged around the heat pump body in the shell body.

[0006] The advantages of the utility model compared with the prior art are: a group of mounting plates on the outer shell body are connected with multiple damping shock absorbers on the top surface of the second support plate by using mounting bolts to penetrate, so that the outer shell body can be quickly installed around the pump body, and the sound-absorbing panel in the outer shell body cooperates with the damping shock absorber to achieve the noise reduction function to a large extent.

[0007] As an improvement, a group of limiting holes are symmetrically provided on the second support plate, a group of grooves are symmetrically provided on the top surface of the first support plate and are located directly below the limiting holes, and a group of limiting plates are symmetrically provided on the shell body and extend into the grooves through the limiting holes, so that the installation of the shell body can be more stable, and the limiting plates can be fixed with bolts.

[0008] As an improvement, a sound insulation board is fixedly provided on the inner wall of the shell body, and a sound insulation cavity is provided between the sound absorbing board and the sound insulation board. The unprocessed noise passing through the sound absorbing board is blocked in the sound insulation cavity by the sound insulation board, so that the sound absorbing board can continuously process and absorb the noise, thereby improving the noise reduction effect.

[0009] As an improvement, the front side wall of the shell body is connected to a group of ventilation mesh panels, which can facilitate heat dissipation and ventilation of the heat pump body.

[0010] As an improvement, a plurality of rubber buffer springs connected to the bottom surface of the second support plate are evenly arranged on the top surface of the first support plate. The rubber buffer springs cooperate with the damping shock absorber to improve the shock absorption effect of the device and reduce noise. BRIEF DESCRIPTION OF THE DRAWINGS

A group of limiting holes 8 are symmetrically penetrated through the second support plate 3, and a group of grooves 9 located directly below the limiting holes 8 are symmetrically provided on the top surface of the first support plate 1. A group of limiting plates 10 that penetrate the limiting holes 8 and extend into the grooves 9 are symmetrically provided on the shell body 4.

At this time, the mounting plate 5 is close to the top of the damping shock absorber 6, and the mounting plate 5 is penetrated by bolts to connect with the damping shock absorber 6 to complete the installation operation of the shell body 4.

[0022] During the operation of the heat pump body 2, the ventilation mesh 13 cooperates with the heat pump body 2 to dissipate heat and ventilation, and the sound-absorbing panel 7 continuously absorbs and processes the noise generated by the heat pump body 2.
