Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

A radiation type air conditioning indoor unit 100 according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 5.

As shown in fig. 2, 3 and 4, the radiant air conditioning indoor unit 100 includes: a housing 1, a heat exchanger 2, a radiant panel 3 and an air flow drive 4.

As shown in fig. 3 and fig. 5, the casing 1 forms an air duct 11 extending in the up-down direction, a first air opening 111 communicating with the air duct 11 is disposed on the upper side of the casing 1, a second air opening 112 communicating with the air duct 11 is disposed on the lower side of the casing 1, and the first air opening 111 is provided with an arc air guide surface 13 extending upward and forward. The heat exchanger 2 is disposed in the casing 1 to cool or heat the air flow in the air duct 11. The radiation panel 3 is provided on the front side of the casing 1, and the radiation panel 3 and the heat exchanger 2 are provided to face each other in the front-rear direction. The airflow driving member 4 is disposed in the housing 1 and used for driving the airflow to circularly enter and exit the air duct 11. In other words, the convection current air that the air formed in the wind channel can adjust the temperature to far away, and the radiation panel can adjust the temperature to near, and the radiant air conditioner of this application has convection heat transfer and radiation heat transfer function simultaneously promptly.

Casing 1 constitutes out the wind channel 11 that extends along the up-down direction, and first wind gap 111 sets up in the upside of wind channel 11, and second wind gap 112 sets up in the downside of wind channel 11, and under the refrigeration mode, under the effect of air current driving piece 4, the air current flows along the extending direction from the bottom up of wind channel 11 in entering casing 1 from second wind gap 112 to carry out the heat transfer in wind channel 11, the air current after the heat transfer flows from first wind gap 111. Or in the heating mode, the air flow enters the housing 1 from the first air opening 111 and flows from top to bottom along the extending direction of the air duct 11.

In the cooling mode, since the first air opening 111 is provided with the arc-shaped air guide surface 13, the arc-shaped air guide surface 13 extends upwards and forwards, and cold air is blown out upwards and forwards from the first air opening 111 under the flow guiding effect of the arc-shaped air guide surface 13.

Because the radiant air conditioner indoor set of this application blows out forward and upwards in the condition cold air of refrigeration mode, and the air current can not be perpendicular or near vertical blow to the ceiling, can effectively avoid the ceiling phenomenon of condensation to appear, and can carry hot-air or cold air to far away for the regulation efficiency of temperature in far away, and then improve indoor temperature's whole speed of adjusting temperature. Therefore, according to the utility model discloses indoor set 100 of radiant air conditioner has convection heat transfer and radiant heat transfer's function simultaneously, through set up forward and the arc wind guide surface 13 that upwards extends in first wind gap 111 department, can make the cold air after the heat transfer blow off towards the front side under the refrigeration mode, the air current is avoided directly blowing the ceiling, thereby can prevent effectively that the ceiling from concentrating the condensation, and can carry hot-air or cold air to far away, accelerate the regulating efficiency of far away temperature, and then improve indoor temperature's whole speed of adjusting temperature.

In the above embodiment, the reason why the cool air is blown out upward and forward is that, on the one hand, the hot air in the room floats up and the cool air blown out from the radiant air conditioning indoor unit 100 sinks down, and heat exchange occurs again during the process of sinking the cool air and floating the hot air, so that the temperature in the room is rapidly equalized, and discomfort of the human body due to the temperature difference in the room is reduced, and on the other hand, the airflow blown out from the first air port 111 does not blow directly on the human body, thereby improving the comfort of the user.

The first air opening 111 is provided with the arc-shaped air guide surface 13, so that the turning transition of the air flow is gentle, and the energy loss caused by the turning process is reduced, so that the air flow can be blown farther. It can be understood that under the condition that the air outlet speed is insufficient, the air supply distance is short, when the indoor area is large, the air flow cannot reach the partial space far away from the indoor unit 100 of the radiant air conditioner, the room temperature can show nonuniformity, specifically, the temperature of the partial area close to the indoor unit is low, the temperature of the partial area far away from the indoor unit is high, the temperature difference in the room is large, and the comfort of the user is affected. This application has further guaranteed indoor temperature's homogeneity through setting up first wind gap 111 department into arc wind-guiding surface 13.

In addition, the radiation panel 3 is arranged to exchange heat with the heat exchanger 2, on one hand, the radiation panel 3 of the radiation type air-conditioning indoor unit 100 can directly exchange heat with indoor air, so that the heat exchange area between the radiation type air-conditioning indoor unit 100 and the indoor air is increased, the temperature change of the indoor air is uniform, the overall indoor temperature is uniform, and the comfort is high; on the other hand, the airflow driven by the airflow driving part 4 enters the air duct 11 and then exchanges heat with the heat exchanger 2 or exchanges heat with indoor air through the radiation panel 3, so that the temperature difference between the temperature of the airflow blown out from the air outlet and the indoor temperature is reduced, the blown-out temperature is prevented from being too cold or too hot, and the uniformity of the indoor temperature can be ensured; on the other hand, the air in the room directly performing radiation heat exchange with the radiation panel 3 is closer to the radiation type air conditioner indoor unit 100, and the airflow blown out by the radiation type air conditioner indoor unit 100 is farther than the radiation type air conditioner indoor unit 100, so that both the nearer and farther areas can effectively exchange heat, and the uniformity of the room temperature is further ensured.

In one embodiment, the heat exchanger 2 is a plate heat exchanger, and in another embodiment, the heat exchanger 2 is a shell-and-tube heat exchanger. The two heat exchangers in the above embodiments are only illustrative and should not be understood as limiting the scope of the present invention, and the heat exchanger in any form should fall within the scope of the present application, for example, the heat exchanger 2 may also be a spray type heat exchanger.

In one embodiment, the airflow driver 4 is an axial fan, and in another embodiment, the airflow driver 4 is a centrifugal fan. The two fan forms in the above embodiments are only illustrative and should not be understood as limiting the scope of the present invention, and any fan in any form should fall within the scope of the present application, for example, the fan may also be at least one of a mixed flow fan or a diagonal flow fan.

In the above embodiment, the arc wind guide surface 13 may be formed by connecting multiple arc surfaces smoothly, may be only one arc surface, or may be formed by connecting an intermediate connection section with multiple arc surfaces. For example, the arc-shaped wind guiding surface 13 on the rear side plate 14 includes a first section 131 and a second section 132 that are connected in sequence from bottom to top, the opening direction of the open opening formed by the first section 131 is opposite to the opening direction of the open opening formed by the second section 132, wherein the open opening of the first section 131 is open in the direction away from the front side plate, and the open opening of the second section 132 is open in the direction toward the front side plate. Of course, it is also possible that both the first segment 131 and the second segment 132 are open towards the front side plate, which is not described in detail here.

In addition, the first air opening 111 and the second air opening 112 in the present application are also only for convenience of understanding and distinction, and it cannot be understood that the first air opening 111 can only be used for air outlet and the second air opening 112 can only be used for air inlet. For example, when refrigeration is needed, the airflow driving member 4 rotates towards the first direction, the airflow enters the air duct 11 from the second air opening 112 located at the lower side, and flows out of the air duct 11 from the first air opening 111 located at the upper side, so that the effect of uniform heat exchange can be achieved; when heating is needed, the airflow driving member 4 rotates in a second direction opposite to the first direction, and the airflow enters the air duct 11 from the first air opening 111 located at the upper side and is sent out of the air duct 11 from the second air opening 112 located at the lower side, so that a foot warming effect can be provided. The second air opening 112 and the first air opening 111 which are spaced up and down can avoid the phenomenon of return air short circuit caused by that the airflow blown out from the first air opening 111 is directly sucked into the return air duct 11, thereby ensuring the cooling and heating effects of the air conditioner.

It should be noted that the "upper side" and the "front side" mentioned above may refer to the up-down direction and the front-back direction as shown in fig. 1, respectively. In embodiments of the invention, the up-down direction and the front-back direction may vary, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the invention. For ease of description of the invention, reference will be made hereinafter to the orientation as shown in figure 1.

As shown in fig. 3, the flow cross section of the first tuyere 111 is gradually reduced along the flow direction of the air current. It can be understood that the flow cross section of the first air opening 111 is gradually reduced, and the "number of strands" of the air flow passing through a certain flow cross section in a unit time does not change, so that the closer to the first air opening 111 the air flow flows along the direction of the air flow, the faster the air flow speed, and thus the farther the air flow blown out from the first air opening 111 is blown out, the temperature adjustment of a space farther away from the indoor unit 100 of the radiant air conditioner can be accelerated, the temperature in a room is more uniform, and the time for the indoor to reach the desired temperature is effectively shortened.

As shown in fig. 1, 3 and 5, the casing 1 is provided with an air deflector 5, and the air deflector 5 is used for adjusting the opening of the first tuyere 111. The air deflector 5 may be used to open or close the first tuyere 111, and the air deflector 5 has a windward side extending upward and forward. The air outlet angle can be further adjusted by arranging the air guide plate 5, so that the air guide plate can meet the requirements of different modes. For example, in the cooling state of the air conditioner, a standard cooling angle of the air deflector 5 can be set, and natural convection of indoor air is realized through the difference between the self weight of cold airflow and the self weight of air, so that the cooling efficiency is improved. Or, the air conditioner can be set with a standard heating angle of the air deflector 5 in the heating mode, and similarly, natural convection of indoor air is realized through the difference between the self weight of hot air flow and the self weight of air, thereby improving the heating efficiency. The air deflector 5 may also be configured to be capable of reciprocating rotation, for example, the air deflector 5 may be driven by a stepping motor, and the reciprocating rotation of the air deflector 5 is realized by controlling the rotation of the stepping motor, so as to realize the air sweeping of the air supply flow in the up-down direction.

In the above embodiment, the air supply assembly may further include a left air sweeping member and a right air sweeping member, and the left air sweeping member and the right air sweeping member are used for adjusting the air outlet angle of the first air opening 111 in the left-right direction.

As shown in fig. 4, a turbulence structure 6 is arranged in the air duct 11, the turbulence structure 6 and the heat exchanger 2 are oppositely arranged in the front and rear direction, and the air flow in the air duct 11 is disturbed by the turbulence structure 6. In one embodiment, the spoiler structure 6 is disposed on the rear side plate 14, the heat exchanger 2 and the spoiler structure 6 are disposed in a front-rear opposite manner, the spoiler structure 6 disturbs the airflow in the air duct 11, so that the airflows in the air duct 11 can be mixed with each other, the airflows can be scattered and then recombined, heat exchange of the airflows in the air duct 11 is uniform, and the temperature of the airflows blown out from the first air opening 111 is uniform. Moreover, the air current after the fan accelerates takes place orderly or unordered local change after vortex structure 6, and more air currents flow to heat exchanger 2, and heat exchange efficiency of heat exchanger 2 also can greatly increased, shortens indoor reaching the warm time.

As shown in fig. 4, the spoiler structure 6 includes: a guide frame 61 extending in the up-down direction, and a plurality of spoiler protrusions 62 formed on the guide frame 61. The air guide frames 61 are arranged at intervals along the left and right direction, the air duct 11 is separated by the air guide frames 61 to form a plurality of sub-ducts (the sub-ducts can be completely separated and can also be mutually communicated), the air flow entering the air duct 11 from the second air opening 112 can be divided into a plurality of strands to enter the sub-ducts respectively, the air flow in the sub-ducts flows along the preset direction under the backflow effect of the air guide frames 61, and the air flow is disturbed to generate disordered direction conversion when meeting the disturbing flow protrusions 62, so that the air flow is scattered and then mixed with other air flows in the sub-ducts or other sub-ducts. After the turbulent flow effect of the turbulent flow bulges 62, the temperature of the air flow blown out from the first air opening 111 is uniform.

As shown in fig. 4, the turbulator protrusion 62 has an arc-shaped surface extending in the up-down direction. Through setting up vortex arch 62 to the arcwall face, can be so that the air current is in the same direction as smooth being led, reduce because of the noise that the air current turned the direction suddenly and produce.

In another embodiment, the spoiler protrusion 62 may also be a guide plane, and the spoiler protrusion 62 is set to be a guide plane forming a certain angle with the flow guiding frame 61 along the airflow flowing direction, so that the airflow can turn along the preset angle.

As shown in fig. 4, the spoiler protrusions 62 are symmetrically disposed with respect to a center line of the deflector frame 61. Wherein, the relative water conservancy diversion frame symmetry of vortex arch 62 sets up means that the both sides of same water conservancy diversion frame 61 all are provided with vortex arch 62, and the interval sets up about water conservancy diversion frame 61 along the upper and lower direction all for the vortex arch 62 of each side, and the vortex arch 62 that is located both sides is symmetrical. Like this, can make the air current that flows out in every subchannel all flow out after roughly the same vortex environment for the air current that flows out keeps the temperature unanimous as far as possible along the left and right direction.

Preferably, as shown in fig. 4, the positions of the turbulence protrusions 62 on two adjacent flow guide frames 61 are different from the positions of the respective flow guide frames 61, and the turbulence protrusions 62 on one of the flow guide frames 61 are staggered corresponding to the turbulence protrusions 62 on the other flow guide frame 61, so that the turbulence effect can be improved.

Of course, the above embodiment is also only illustrative, for example, the spoiler protrusions 62 on both sides of the same air guiding frame 61 may also be disposed asymmetrically.

In some embodiments, the heat exchanger 2 may be a parallel flow heat exchanger or a microchannel heat exchanger. The adoption of the parallel flow heat exchanger or the micro-channel heat exchanger can save energy, and the energy saving is an important index of the current air conditioner. Conventional heat exchangers 2 are difficult to manufacture for high grade, e.g., class i, energy efficiency standards, and microchannel heat exchangers would be the best choice to address this problem. For example, in the aspect of household air conditioners, when the size of a flow channel is smaller than 3mm, the law of gas-liquid two-phase flow and phase-change heat transfer is different from the conventional larger size, the smaller the flow channel is, the more obvious the size effect is, and when the inner diameter of the pipe is as small as 0.5-1mm, the convective heat transfer coefficient can be increased by 50% -100%. The enhanced heat transfer technology is used for the air-conditioning heat exchanger, so that the heat transfer of the air-conditioning heat exchanger can be effectively enhanced, and the energy-saving level of the air-conditioning heat exchanger is improved.

Of course, the above-mentioned embodiments are not to be construed as limiting the scope of the present invention, and the heat exchanger 2 may also be a plate-and-tube heat exchanger 2, for example.

The airflow driving part 4 is a cross-flow wind wheel or a centrifugal fan. When the cross-flow wind wheel works, the airflow does not change direction along the axial direction of the cross-flow wind wheel, and the airflow passes through the impeller and flows under the action of twice forces of the blades, so that the airflow can reach a far distance, and the air supply distance can be increased by adopting the cross-flow wind wheel. The centrifugal fan can change the direction of the air flow, so that the positions of the second air opening 112 and the first air opening 111 can be selectively opened by arranging the centrifugal fan, and the selection is more diversified.

As shown in fig. 2, 4 and 5, the lower side of the housing 1 is provided with a cylindrical structure 7 extending in the left-right direction, the cylindrical structure 7 is provided with a first air opening 111 or a second air opening 112 opened to the front side, and the airflow driving member 4 is provided in the cylindrical structure 7.

The above embodiments are also merely illustrative, and for example, the lower side of the housing 1 may be provided with a square structure, a tapered structure, an elliptical structure, or the like extending in the left-right direction. And the second tuyere 112 may not only be provided to be opened toward the front side of the cylindrical structure 7, but the second tuyere 112 may also be provided to be opened toward at least one of the rear side, the left side and the right side of the cylindrical structure 7.

As shown in fig. 5, the outer surface of the cylindrical structure 7 is provided with ribs 71 distributed in the circumferential direction. The plurality of fins 71 arranged at intervals along the circumferential direction of the cylindrical structure are arranged, so that the airflow is scattered and redistributed when entering the second air port 112, mixed flow is realized, the temperature of the airflow before heat exchange is kept uniform, and the outlet air temperature is uniform. In addition, the arrangement of the fins 71 also helps to strengthen the structural strength of the cylindrical structure 7, improve the bearing capacity of the cylindrical structure 7, enable the airflow driving part 4 to be stably installed, and enable the radiation type air conditioning indoor unit 100 to be stably hung on a wall.

Because according to the utility model discloses indoor set 100 of radiant air conditioner through setting up forward and the arc wind-guiding surface 13 that upwards extends in air outlet department, can make the air current after the heat transfer blow off towards the front side, avoided the air current directly to blow the ceiling to can prevent effectively that the ceiling from concentrating the condensation, the air conditioner that has indoor set 100 of above-mentioned radiant air conditioner also has above-mentioned advantage.

In the above embodiment, the second air openings 112 may be provided with purification components, and the purification components may filter and purify the fresh air flow and the indoor return air flow, for example, the purification components may be arranged as a hypa filter screen, or the purification components may be arranged as an electrostatic dust removal device.
