Description

Technical Field

[0001] This invention belongs to the technical field of indoor cooling equipment, specifically a ventilation and cooling device that takes into account the temperature difference between indoors and outdoors. Background Technology

[0046] Please see Figure 1In this embodiment of the invention, a ventilation and cooling device that takes into account the temperature difference between indoors and outdoors includes:

[0047] Install the main pipe 1 horizontally, which is suspended from the indoor ceiling by a fixed bracket;

[0048] Transfer pipe 3 is connected to the installation main pipe 1;

[0049] An exhaust fan blade is installed on the exterior wall panel. The exhaust fan blade is connected to the other end of the transfer pipe 3 and is used to introduce outdoor airflow into the installation main pipe. A filter screen is also installed between the exhaust fan blade and the installation main pipe to filter the outdoor airflow so as to form fresh airflow.

[0050] The refrigeration compressor 4 is installed on the outdoor wall panel and is used to compress and discharge the refrigerant gas flow. One end of the refrigeration compressor 4 is connected to the exhaust pipe, and one end of the exhaust pipe is sealed and passed through the main installation pipe 1.

[0051] The inner transmission tube 2 is coaxially disposed inside the main installation tube 1. One end of the inner transmission tube 2 is connected to the exhaust pipe, and the other end is provided with a sealing end piece.

[0052] Multiple mixed-flow conveying components 5 are arranged in an array, each of which is vertically connected to the main installation pipe 1, and each mixed-flow conveying component 5 is connected to the inner transmission pipe 2; and

[0053] An internal air exhaust assembly 6 is suspended on the indoor ceiling. One end of the internal air exhaust assembly 6 is connected to the mixed flow exhaust assembly 5 and is used to circulate and exhaust indoor air.

[0054] In this embodiment, the mixed-flow conveying component 5 includes:

[0055] Outer cylinder seat 51;

[0056] A sealing seat 52 is embedded and fixed on the main installation tube 1, and one end of the sealing seat 52 is connected to the outer cylinder seat 51.

[0057] An inner connecting tube 53 is coaxially disposed inside the outer cylinder seat 51, and the other end of the inner connecting tube 53 is connected to the transmission inner tube 2.

[0058] The inner mixing chamber 54 is coaxially embedded and fixed in the outer cylinder seat 51. The inner mixing chamber 54 is connected to the sealing seat 52 and the inner connecting pipe 53 for the initial mixing of outdoor airflow and refrigerant airflow.

[0059] The discharge cavity 56 is coaxially fixed in the outer cylinder seat 51. The discharge cavity 56 is connected to the inner mixing chamber 54 through the inner pipe fitting 55, and the inner wall of the discharge cavity 56 has an inverted conical structure.

[0060] A guide fan blade 57 is coaxially mounted in the exhaust chamber 56, allowing relative rotation. A micro motor is mounted on the exhaust chamber 56, and the output of the micro motor is connected to the guide fan blade 57 via gear meshing. This system is used to fully integrate outdoor airflow with refrigerant airflow, thereby achieving initial cooling based on the outdoor airflow.

[0061] The transfer device 7 is coaxially connected below the outer cylinder seat 51.

[0062] As a preferred embodiment, it also includes:

[0063] The inner guide cover 81 is coaxially sleeved and fixed in the outer cylinder seat 51, located below the discharge cavity.

[0064] The diffuser 8 is vertically fixed below the inner guide cover 81. The diffuser 8 is constructed as a double-layer axial tube structure, and its inner tube body is provided with multiple through holes.

[0065] The outer branch pipes 83 are multiple ones arranged in a circular array, and one end of each outer branch pipe 83 is connected to the inner connecting pipe 53.

[0066] The diversion duct 82 is provided corresponding to each of the outer branch pipes 83. One end of the diversion duct 82 is connected to the outer branch pipe 83, and the other end is connected to the diffuser pipe 8 through multiple inner pipe fittings. In particular, the outer branch pipe can directly deliver the refrigerant airflow to the diffuser pipe. The multiple through holes on the diffuser pipe can fully diffuse and discharge the refrigerant airflow and merge it with the cooled outdoor airflow for secondary cooling, thereby precisely adjusting the cooling of the outdoor airflow. Especially when the indoor air is introduced later, the indoor mixing chamber can preferentially and fully merge the outdoor airflow with the indoor air. At this time, the fresh air can be formed based on the cooling of the outdoor airflow or the heating of the indoor airflow by controlling the discharge flow rate. Then, the diversion duct delivers the refrigerant airflow for secondary precise cooling adjustment.

[0067] In this embodiment, the transfer device 7 includes:

[0068] The telescopic guide tube 71 is vertically connected below the outer cylinder seat 51;

[0069] The conveyor base 72 is connected below the telescopic conduit 71;

[0070] The electric telescopic rod 73 is rotatably connected between the outer cylinder base 51 and the conveyor base 72 via a universal joint; and

[0071] The diffuser 74 is fitted and fixed below the discharge base 72 to allow for full diffusion from multiple angles.

[0072] In this embodiment, an outflow pipe 75 is also provided on one side of the exhaust base 72, and one end of the outflow pipe 75 is connected to the internal air exhaust assembly 6.

[0073] In this embodiment, the internal air supply component 6 includes:

[0074] An external guide pipe 61 is horizontally suspended below the indoor ceiling. One end of the external guide pipe 61 is connected to a circulating air pump (not shown in the figure) to circulate and guide indoor airflow.

[0075] A purification cylinder 62 is connected to the other end of the external guide pipe 61. The purification cylinder 62 is provided with a coarse filter, a fine filter layer and an adsorption layer 63 arranged obliquely from top to bottom.

[0076] External discharge pipe 64 is connected below the purification cylinder 62; and

[0077] The delivery branch pipe 66 is connected to the external exhaust pipe body 64. The other end of the delivery branch pipe 66 is connected to the side of the installation main pipe 1 away from the exhaust fan blades. The delivery branch pipe can deliver the purified indoor air to the installation main pipe and fully integrate it with the outdoor airflow so that the input outdoor airflow can be locally heated and regulated based on the indoor air temperature.

[0078] In a preferred embodiment, one side of the purification cylinder 62 is connected to an external airflow pipe 65 between each of the coarse filter, fine filter layer and adsorption layer 63. The external airflow pipe is used to guide purified gas of different concentrations in layers between each coarse filter, fine filter layer and adsorption layer, so as to fully purify the indoor air that is circulated.

[0079] In this embodiment, the outflow pipe 64 is also provided with a connecting pipe 67, which is connected to each outflow pipe 75 in the mixed flow delivery assembly 5. The connecting pipe 67 and the delivery branch pipe 66 can supply and transmit air relatively independently or synchronously. In use, when the delivery branch pipe works independently, the indoor air and the outdoor airflow collide and merge to form fresh air based on the outdoor airflow cooling or the indoor air temperature rising. Then, the refrigerant airflow is merged and cooled to form cold air. Under long-term conditions, the indoor temperature is lower than the outdoor temperature. When the connecting pipe works independently, the outdoor airflow and the refrigerant airflow merge to form cooling based on the outdoor airflow. Then, the input indoor air forms ventilation and cooling based on the indoor air, making the indoor temperature lower than the original indoor temperature, but higher than the outdoor temperature. When the delivery branch pipe and the connecting pipe work synchronously, the ventilation and cooling based on the indoor air is more obvious. At this time, the temperature difference between indoor and outdoor is relatively small.

[0080] Specifically, in ventilation and cooling, the exhaust fan blades introduce outdoor airflow into the main installation pipe, and the refrigeration compressor compresses and discharges the refrigerant airflow to the transmission inner pipe. At this time, the inner air exhaust assembly can first mix the indoor air with the outdoor airflow through the delivery branch pipe, while the inner mixing chamber initially mixes the refrigerant airflow with it, and the diffuser pipe delivers the refrigerant airflow to it for secondary cooling and regulation. The transfer and exhaust device diffuses and discharges the cooled airflow, and the connecting pipe in the inner air exhaust assembly can deliver indoor air again through the exhaust fan base, forming ventilation and cooling based on indoor air.

[0081] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
