This application claims the foreign priority benefit of Czech Patent Application Serial No. PUV 2017-34344 entitled “A device for elimination of noise propagation,” filed Nov. 14, 2017, the entire disclosure of which is incorporated herein by reference in its entirety.
The technical solution of the present invention relates to a device for the elimination of noise propagation. In particular, the present invention relates to noise limitation for devices intended to be used for compression of gases and vapours.
The use of devices for the compression of gases and vapours, such as compressors, are widely used in various industrial applications. However, such compression devices, particularly compressors, may produce much vibration and noise, which may be very unpleasant and undesirable when used in a quiet environment. Generally, pads and shock absorbers have been used to prevent the vibrations and accompanying noise from these compression devices from escaping into the surrounding environment. Furthermore, soundproof packaging generally made from highly absorbent polyester non-woven fabric has also been used for sound insulation of compressors. Additionally, compressors have also been packaged in hard films for further controlling and mitigating undesirable sounds from the compressors. Yet another known solution for reducing noise of compressor involves the use of aluminium foil.
The drawback of these solutions is the lack of preventing the penetration of noise into the surrounding environment.
The abovementioned disadvantages are remedied by the device of the present invention, which is able to effectively mitigate excess noise and vibrations produced from compressors and other compression devices used to compress gas and vapours. Generally, the device of the present invention comprises at least one base plate, on which at least one compression device for the compression of gases and vapours is positioned. The compression device may comprise at least one flexible pipe for suction and at least one flexible pipe for displacement. Moreover, the base plate may be provided with at least one impermeable wrapping, which may be connected to the base plate via a hermetic joint. Additionally, the base plate and/or the impermeable wrapping may be provided with at least one valve for creating a vacuum. Also, the base plate and/or the impermeable wrapping may be provided with at least one hermetically adjusted opening for placement of the flexible pipe and/or conductors.
Generally, it is preferable that the impermeable wrapping be provided with a valve.
It is also advantageous that the base plate be provided with at least one hermetically adjusted opening for the placement of the pipe of the compression device. Furthermore, the impermeable wrapping may be provided with at least one opening for the placement of electrical wires.
It is useful that the base plate be provided with at least one anti-vibration means.
The device for elimination of noise propagation provides an efficient exclusion of noise and vibration during the operation of the compressors, especially when used in combination with alternative sources of heat, such as heat pumps or cold sources, such as a refrigerator, a cooling box, or freezing boxes.
The main advantage of the technical solution is the possibility of easy application while ensuring a high anti-noise result.
Another advantage of the present invention is that it may increase the efficiency of the device by limiting the thermal (energy) losses of the compressor and, consequently, may therefore increase the life of compressors.
Another advantage of the device of the present invention is that it may provide protection of the compression device against external environmental influences, such as corrosion.
Other benefits of the device of the present invention include the simplicity of the structural arrangement of the device, the low cost to produce the device, and the variability of the device in its use in connection with industrial applications wherever there is a need to reduce the noise level of operating equipment.
Embodiments of the present invention are described herein with reference to the following drawing figures, wherein:
Reference to
Typically, the compression device for the compression of gases and vapours 2 is connected with the base plate 1. In preferred embodiments, the compression device 2 is removably connected to the base plate 1 by means of screw joints.
The base plate 1 and the compression device 2 may be provided with at least one impermeable wrapping 4. In preferred embodiments, this impermeable wrapping 4 is a steel wrapping. The base plate 1 and the impermeable wrapping 4 may be connected through a hermetic joint 3 for ensuring an internal environment different from the outside environment. The hermetic joint 3 can be, for example, a weld joint.
Furthermore, in various embodiments, the base plate 1 and/or the impermeable wrapping 4 may be provided with at least one valve 5 for creating a vacuum. In preferred embodiments, the valve 5 for creating a vacuum is located on the impermeable wrapping 4.
Furthermore, in various embodiments, the base plate 1 and/or the impermeable wrapping 4 may be provided with at least one hermetically adjusted opening 6 for the location of the flexible pipes 21, 22 and/or the conductors 7. In preferred embodiments, the opening 6 is located in the base plate 1 and is adapted for the insertion of the flexible pipes 21, 22.
As shown in
In various embodiments, to reduce the transmission of vibrations, the base plate 1 is provided with anti-vibrating means 8. In preferred embodiments, the anti-vibrating means 8, 8′ are located symmetrically on the base plate 1.
The device for elimination of noise propagation may create a vacuum via the valve 5, which is connected with a vacuum pump. More particularly, this vacuum configuration with the vacuum pump may create a vacuum in the internal environment between the base plate 1 and the impermeable wrapping 4. Furthermore, the device of the present invention may be connected with a particular product, such as a heat pump or refrigerator, through the flexible pipe 21, 22. Moreover, by using wires from the conductor 7 or an electro clutch, the device for elimination of noise propagation may be connected to a current source. After starting the heat pump, the compression device 2 is switched on and works in its standard and conventional way, except the noise and vibration associated with its operation are detained in the indoor environment. In exemplary embodiments, the device of the present invention can be connected with a refrigerator in order to mitigate the sounds and vibrations produced by the refrigerator's compressor.
The device according to the technical solution can be advantageously used in all industrial applications where it is necessary or beneficial to deter the adverse effects of the noise and vibrations emitted by compressors and other compression devices.
It should be understood that the following is not intended to be an exclusive list of defined terms. Other definitions may be provided in the foregoing description, such as, for example, when accompanying the use of a defined term in context.
