Description

Technical Field

[0001] This utility model belongs to the field of heat pump technology, specifically relating to an energy-saving and noise-reducing heat pump protection structure applied to building heating systems. Background Technology

[0002] In building heating systems, heat pumps, as a highly efficient and energy-saving heating device, operate on the principle of consuming a small amount of electricity to drive a compressor. This allows the refrigerant to undergo a state transformation within a circulation system consisting of a compressor, plate heat exchangers, and other auxiliary components, thereby achieving efficient heat transfer. The compressor compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas. When this gas enters one side of the plate heat exchanger, it releases heat (at this time, the plate heat exchanger acts as a condenser, heating the circulating chilled water in the building heating network). After releasing heat, the refrigerant is throttled and depressurized before entering the other side of the plate heat exchanger (or another plate heat exchanger), where it absorbs heat from a low-temperature heat source (such as outdoor air or groundwater) (at this time, the plate heat exchanger acts as an evaporator). The refrigerant, after absorbing heat, is then drawn back into the compressor, and this cycle repeats continuously, transferring heat from the low-temperature environment to the interior of the building, providing a stable heat source for indoor heating.

[0003] However, heat pumps generate various types of noise during building heating operations, significantly disrupting the building and its surrounding environment. The main noise sources include: mechanical vibration noise from the compressor during operation, which is transmitted to the building structure through the equipment base, causing solid-borne sound; airflow impact noise from the rapid flow of refrigerant within the pipes during operation, and resonance noise from pressure fluctuations in the pipes, which easily diffuses through building pipe shafts, equipment rooms, and other spaces; in addition, the motor driving the compressor generates a combination of aerodynamic, mechanical, and electromagnetic noise.

[0004] These noises propagate within buildings through two pathways: airborne and solid-borne. Airborne noise diffuses into residents' homes along corridors, windows, and other pathways. Solid-borne noise, on the other hand, propagates through building structures such as walls and floors. Low-frequency noise, in particular, is difficult to control due to its slow attenuation, long wavelength, and strong penetrating power. It often penetrates building walls and floors, causing continuous disruption to residents' daily lives and becoming an urgent environmental problem to be solved in building heating systems. Utility Model Content

[0005] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide an energy-saving and noise-reducing heat pump protection structure for use in building heating systems.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] An energy-saving and noise-reducing heat pump protection structure for building heating systems includes a chassis support, a protective shell mounted on the chassis support, polyurethane shock-absorbing blocks installed between the chassis support and the protective shell, a plurality of rubber shock-absorbing blocks vertically fixedly installed at the bottom inside the protective shell, a bottom support plate mounted on the top of the rubber shock-absorbing blocks, and a compressor and a plate heat exchanger mounted on the bottom support plate.

[0008] The protective shell comprises, from the outside to the inside, a protective and sound-insulating sheet metal layer, a rigid sound-insulating material layer, and a soft sound-insulating material layer, and the protective shell is provided with heat dissipation vents.

[0009] Further specifying, the bottom of the protective shell is equipped with rubber shock-absorbing feet, and the compressor is mounted on the rubber shock-absorbing feet.

[0010] Furthermore, the outer wall of the compressor is also made of the protective sound-insulating sheet metal layer, the rigid sound-insulating material layer, and the soft sound-insulating material layer.

[0011] Furthermore, the compressor's piping connections utilize stainless steel vibration-damping tubing.

[0012] Furthermore, the pipe connections of the plate heat exchanger are made of rubber soft water pipes.

[0013] The beneficial effects of using this utility model are as follows:

[0014] This utility model "builds a house" for the compressor, forming a three-layer soundproof barrier with a protective soundproof sheet metal layer, a hard soundproof material layer, and a soft soundproof material layer to ensure noise reduction effect;

[0015] This invention uses polyurethane shock absorbers to isolate vibrations between the chassis support and the protective shell, and rubber shock absorbers to isolate vibrations between the protective shell and the bottom support plate. This dual isolation ensures effective vibration reduction. Attached Figure Description

[0024] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1:

[0026] like Figures 1-5 As shown, the present invention provides an energy-saving and noise-reducing heat pump protection structure for building heating systems, including a chassis support 1, a protective shell 2 installed on the chassis support 1, a polyurethane shock absorber 3 installed between the chassis support 1 and the protective shell 2, a plurality of rubber shock absorbers 4 vertically fixedly installed at the bottom inside the protective shell 2, a bottom support plate 5 installed at the top of the rubber shock absorbers 4, and a compressor 6 and a plate heat exchanger 7 installed on the bottom support plate 5.

[0027] The protective shell 2 consists of a protective and sound-insulating sheet metal layer 8, a rigid sound-insulating material layer 9, and a soft sound-insulating material layer 10 from the outside to the inside. The protective shell 2 is provided with a heat dissipation vent 11.

[0028] In this implementation case, the entire heat pump unit is installed at the usage position via the chassis bracket 1, and then the protective shell 2 is installed on it. It should be emphasized that a polyurethane damping block 3 is installed between the protective shell 2 and the chassis bracket 1. Under the effect of the polyurethane damping block 3, the protective shell 2 is damped and buffered to a certain extent, thereby reducing the noise generated by the collision and vibration between mechanical structures. With the inherent characteristics of the protective shell 2, it plays a protective role for the heat pump system installed inside.

[0029] Furthermore, a bottom support plate 5 is installed at the bottom inside the protective shell 2. The compressor 6 and plate heat exchanger 7 of the heat pump system, including but not limited to, are then installed on the bottom support plate 5. The rubber shock-absorbing block 4 installed between the bottom support plate 5 and the protective shell 2 enhances the buffering effect, that is, enhances the noise reduction effect.

[0030] Furthermore, the multi-layered structure of the protective shell gives it excellent noise reduction and protection effects.

[0031] Example 2:

[0032] like Figure 2 , Figure 4 As shown, a rubber shock-absorbing foot 12 is installed at the bottom inside the protective shell 2, and the compressor 6 is installed on the rubber shock-absorbing foot 12.

[0033] In this implementation case, further noise reduction protection is provided for the compressor 6, which has relatively strong vibration and noise. The rubber shock-absorbing feet 12 also serve to buffer and absorb vibration, thereby reducing noise.

[0034] Example 3:

[0035] like Figure 5 As shown, the outer wall of the compressor 6 is also made of a protective sound insulation sheet metal layer 8, a rigid sound insulation material layer 9, and a soft sound insulation material layer 10;

[0036] In this implementation case, the compressor 6, which has relatively strong vibration and noise, is further protected against noise by using the same material as the protective shell 2 to absorb vibration and thus reduce noise.

[0037] Example 4:

[0038] like Figure 2 , Figure 3 As shown, the piping connections of compressor 6 use stainless steel vibration damping pipes;

[0039] In this implementation case, stainless steel vibration damping pipes are used for pipeline connections. Leveraging the excellent corrosion resistance, high temperature resistance, and high strength of stainless steel, these pipes can adapt to various complex working conditions such as chemical and humid environments, effectively resisting media erosion and external wear, thus extending service life. Simultaneously, their special corrugated pipe structure can flexibly compensate for pipeline displacement caused by temperature changes, vibration, or installation deviations, significantly reducing vibration transmission, minimizing stress damage to pipelines and connected equipment, and providing buffering and shock absorption. This ensures the stability and safety of system operation, combining durability and functionality.

[0040] Example 5:

[0041] like Figure 2 , Figure 3 As shown, the piping connections of the plate heat exchanger 7 use rubber soft water pipes;

[0042] In this implementation case, the pipe connections of the plate heat exchanger use rubber soft water pipes. The excellent flexibility of rubber material can easily adapt to minor deviations during pipe installation, simplifying the connection process. Its excellent elasticity can effectively absorb the vibration and noise generated by the equipment operation, reducing the impact of pipe resonance on the system. At the same time, the rubber material has certain temperature resistance and corrosion resistance, which can adapt to common water temperature changes and ordinary media environments in heat exchangers. It is also lightweight and low-cost, making it easy to maintain and replace later. While ensuring the connection sealing, it also takes into account the convenience of installation and the economy of use.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
