Description
Technical Field
The invention belongs to the field of air conditioning devices, and particularly relates to an air conditioner indoor unit and an air conditioner.
Background
At present, an air conditioner for conditioning indoor air is generally of a blowing type, that is, a forced convection heat exchange method is adopted to regulate the temperature of an indoor space. The mode can change the room temperature rapidly, and the heat transfer efficiency is higher. However, the blowing feeling caused by the heat convection is strong, the operation noise is large, and uncomfortable use experience is easily brought to a user.
The radiation air conditioner mainly adopts a radiation panel to perform radiation heat exchange with the external environment, thereby achieving the purpose of adjusting the room temperature. The radiation heat exchange mode does not need to force airflow to flow, and has the advantages of comfort, silence, no wind feeling and the like. However, since the radiation heat exchange is started slowly, the radiation panel cannot reach the temperature set by the user in a long time after the start-up, and the start-up and stop are difficult to achieve.
The forced convection heat exchange and radiation heat exchange modes are combined, so that the air conditioner has the comfort of radiation heat exchange and the high efficiency of convection heat exchange, and the current combined air conditioner has less application. After the air conditioning system operates for a period of time, the temperature of the radiation panel can become very high or very low due to the thermal inertia of the radiation panel, so that the heat exchanger positioned at the back side of the radiation panel is heated or cooled, and particularly, under the conditions that the air inlet is far away from the heat exchanger, or the wind resistance is large and the air quantity is small, the temperature change of the air flowing through the heat exchanger is not large, so that the heat exchange medium in the heat exchanger cannot be subjected to normal phase change, and the heating or refrigerating capacity of the air conditioner is insufficient.
Chinese patent document CN103314259A discloses an air conditioner with radiation heating, hot air heating and cold air cooling modes. The air conditioner has a radiation heat exchanger of a radiation panel and an indoor heat exchanger arranged in parallel. When the operation mode is switched to the hot air heating operation mode, the high-temperature heat exchange medium does not flow to the heat exchanger of the radiation panel, but only flows to the indoor heat exchanger, so that the problem that the surface temperature of the radiation heat exchanger is not reduced is solved. But the air conditioner has few optional modes and a non-radiation refrigeration mode, when the indoor temperature is reduced to the set temperature, the cold air refrigeration mode is still needed to maintain the indoor low temperature, the blowing feeling is strong, the energy consumption is high, and the air conditioner is not beneficial to improving the use comfort level of the air conditioner and meeting the requirements of energy conservation and environmental protection.

Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments. In the following description, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
It should be noted that the "upper portion" hereinafter refers to a position higher in the vertical direction; "lower" means a position lower in the vertical direction.
As shown in fig. 1 to 4, the present embodiment relates to an indoor unit of an air conditioner, including:
the radiation heat exchanger comprises a shell, a heat exchanger and a heat exchanger, wherein the shell comprises a radiation panel 1 formed on one side wall surface of the shell and an accommodating cavity 4 arranged in the shell, and the radiation panel 1 is used for performing radiation heat exchange with the environment; the shell is also provided with an air inlet 6 and an air outlet 7 which are communicated with the accommodating cavity 4;
and the heat exchanger 3 is arranged in the accommodating cavity 4 and is close to the air inlet 6.
The indoor unit of the air conditioner comprises a radiation panel 1 for radiation heat exchange with the environment and a heat exchanger 3 for convection heat exchange, so that the radiation heat exchange and the convection heat exchange can be combined together, after the indoor unit is started, the indoor temperature can rapidly reach a set value mainly in the convection heat exchange mode, and the heating or refrigerating requirements of users are met. After the indoor unit of the air conditioner operates stably, the indoor unit of the air conditioner is mainly adjusted in room temperature in a radiation heat exchange mode, the silencing effect is good, no wind is felt, and the use comfort level is high.
Generally, after an indoor unit of an air conditioner is in stable operation, the temperature of the radiation panel 1 is usually kept at a higher/lower temperature value, and radiation heat exchange is performed between the radiation panel and the accommodating cavity 4 to a certain degree, so that the temperature of air flow entering the heat exchanger 3 is too high/too low, and the heat exchange medium in the heat exchanger 3 cannot normally perform phase change operation. At this moment, the heat exchanger 3 is arranged close to the air inlet 6, the length of an air channel from the air inlet 6 to the heat exchanger 3 is shortened, the influence of overhigh or overlow temperature of the radiation panel 1 on the temperature of the air inlet flow is reduced, the temperature of the air inlet flow exchanging heat with the heat exchanger 3 is not lower than the boiling point of the heat transfer medium in the heat exchanger 3 in a refrigeration mode, and the temperature of the air inlet flow is not higher than the boiling point of the heat transfer medium in a heating mode, so that the normal phase change of the heat transfer medium in the heat exchanger 3 is ensured, and the refrigeration or heating capacity of an indoor unit of an air conditioner is ensured to be sufficient.
Preferably, the housing is vertically arranged, and the air inlet 6 and the air outlet 7 are respectively arranged at different vertical heights on the housing. The vertically arranged shell enables the specific arrangement heights of the air inlet 6 and the air outlet 7 to have a larger optional range, and a user can select the height suitable for the air inlet and the air outlet according to needs.
As shown in fig. 1 and fig. 2, as a preferred embodiment, the air inlet 6 is disposed in a vertical middle portion of the radiation panel 1, and at least one air outlet 7 is disposed on the radiation panel 1 and vertically above and below the air inlet 6.
The air outlet 7 is arranged above and below the air inlet 6, so that the air conditioner indoor unit can intake air from the middle part of the radiation panel 1 and exhaust air from the upper end and the lower end of the radiation panel 1. The setting mode shortens the path length of the air flow in the indoor unit of the air conditioner on one hand, and the air flow temperature is less influenced by the temperature of the radiation panel 1, thereby ensuring that the air flow can ensure that the heat exchange medium in the heat exchanger 3 is normally changed in phase. On the other hand, the air outlet 7 is arranged up and down, so that a user can selectively open or close the air outlet 7 at different vertical heights according to different requirements. For example, when heating, the hot air with smaller specific gravity enters the room from the air outlet 7 at the lower part, so that the hot air can directly act on the actual activity area of the user, and the effect of falling the hot air to the ground is achieved. During refrigeration, cold air with large specific gravity can enter a room from the air outlet 7 at a higher position, and the cold air flows from top to bottom to integrally cool the room, so that the cooling effect of the indoor unit of the air conditioner is optimized.
Preferably, the heat exchanger 3 is disposed in the vertical middle of the accommodating cavity 4 at a position corresponding to the air inlet 6, a fan 2 for enhancing heat exchange is disposed on one side of the heat exchanger 3 away from the air inlet 6, and the fan 2 can promote airflow to flow from the air inlet 6 to the air outlet 7 in a directional manner and improve heat exchange efficiency of the heat exchanger 3.
Further preferably, the heat exchanger 3 is in the form of a straight plate or a flap, preferably a V-shaped structure. When the heat exchanger 3 is in a straight plate form, the heat exchange plane of the heat exchanger 3 is arranged right opposite to the air inlet 6, so that the heat exchange area of the heat exchanger 3 is effectively increased, and the heat exchange efficiency is improved; when the heat exchanger 3 is in a V-shaped structure, the opening direction of the V-shaped structure is opposite to the air inlet 6, the arrangement mode can better utilize the distribution of the air speed of the inlet air, and the heat exchange efficiency is improved. It should be noted that the structural form of the heat exchanger 3 is not limited to a straight plate shape and a folded plate shape, and may be any other structural form that facilitates heat exchange.
Preferably, the fan 2 is a centrifugal fan or a mixed flow fan, and it should be noted that the type of the fan 2 is not limited to the two fan types, and may be any type of fan that can enhance heat exchange and promote airflow from the air inlet 6 to the air outlet 7.
As shown in fig. 3 and 4, as a preferred embodiment, a partition plate 5 is disposed in the accommodating chamber 4, and the partition plate 5 partitions the accommodating chamber 4 into an upper air flow passage 41 at an upper portion and a lower air flow passage 42 at a lower portion.
The air inlet 6 comprises at least one upper air inlet 61 communicated with the upper air flow channel 41, and the upper air inlet 61 is arranged on the radiation panel 1 and close to the partition plate 5; the air inlet 6 further includes at least one lower air inlet 62 communicated with the lower air flow passage 42, and the lower air inlet 62 is disposed on the radiation panel 1 near the partition 5.
The air outlet 7 comprises at least one upper air outlet 71 arranged vertically above the upper air inlet 61, and a one-way airflow channel is formed from the upper air inlet 61 to the upper air outlet 71; the air outlet 7 further includes at least one lower air outlet 72 disposed vertically below the lower air inlet 62, and another one-way airflow channel is formed from the lower air inlet 62 to the lower air outlet 72. The number of the upper air inlets 61 and the lower air inlets 62 may be determined according to the requirement of the specific air inlet and outlet amount.
Preferably, there are two partitions 5, and the two partitions 5 are disposed at intervals to divide the accommodating chamber 4 into the upper air flow passage 41, the lower air flow passage 42 and the partition 43; the arrangement of the two partition plates 5 shortens the vertical lengths of the upper airflow channel 41 and the lower airflow channel 42, so that the vertical lengths of the upper airflow channel 41 and the lower airflow channel 42 are not more than half of the vertical height of the shell, the influence of the radiation panel 1 on the temperature of the intake airflow can be further reduced, and the normal phase change and work of the heat exchange medium in the heat exchanger 3 can be ensured.
Preferably, the upper heat exchanger 31 and the upper fan 21 are sequentially arranged in the upper airflow channel 41 from the upper air inlet 61 to the upper air outlet 71, and the lower heat exchanger 32 and the lower fan 22 are sequentially arranged in the lower airflow channel 42 from the lower air inlet 62 to the lower air outlet 72. The upper fan 21 drives the gas in the upper airflow channel 41 to exchange heat through the upper heat exchanger 31 and then flow out of the indoor unit of the air conditioner, and the lower fan 22 drives the gas in the lower airflow channel 42 to exchange heat through the lower heat exchanger 32 and then flow out of the indoor unit of the air conditioner. Similarly, the upper heat exchanger 31 and the lower heat exchanger 32 are preferably, but not limited to, straight plates or folded plates, and the upper fan 21 and the lower fan 22 are preferably, but not limited to, cross-flow fans or axial-flow fans, and any other fans that can drive airflow in the above directions to enhance heat exchange can be used.
Preferably, the air inlet 6, the air outlet 7, the upper air inlet 61, the lower air inlet 62, the upper air outlet 71 and the lower air outlet 72 are all arranged as openings in a grid shape, a louver shape or a circular hole shape, so as to ensure sufficient air inlet and outlet amount and meet the overall requirements of users on air inlet and outlet forms and air inlet and outlet appearances.
Preferably, the radiation panel 1 is configured as a straight panel or a curved panel, and more particularly, the shape and structure of the radiation panel 1 may be changed according to the interior decoration style, so that the shape of the indoor unit of the air conditioner may be designed as a screen type, a mural type or other forms that can be integrated and adapted with the interior decoration, thereby meeting the requirements of users on beauty and individuality. One side of the radiation panel 1, which is positioned inside the accommodating cavity 4, is further coated with a heat insulation material so as to reduce heat exchange of the radiation panel 1 to airflow in the accommodating cavity 4.
As a preferred embodiment, a heat transfer channel for conducting a heat transfer medium is arranged between the radiation panel 1 and the heat exchanger 3; the heat transfer channel connects the radiation panel 1 and the heat exchanger 3 in series or in parallel. Here, the series connection means that a heat transfer medium flows through the heat exchange structure of the radiation panel 1, then flows into the heat exchanger 3, exchanges heat with an air flow, and finally flows out to the outdoor unit of the air conditioner. The parallel connection mode means that heat transfer media can flow into the radiation panel 1 and the heat exchanger 3 respectively without influencing each other according to flow distribution, and are converged to enter the outdoor unit of the air conditioner after phase change heat exchange.
The indoor unit of the air conditioner has the following operation modes:
more specifically, a preferred operation of the indoor unit of the air conditioner is designed as follows:

In the cooling mode, when the air conditioner is started up, the upper air outlet 71 and the lower air outlet 72 can simultaneously output air, so that the rapid cooling effect is ensured. And after the air conditioner stably operates, the lower air outlet 72 is closed, and only the upper air outlet 71 is used for air outlet. After reaching the preset temperature, the fan 2 runs at a lower rotating speed or stops running so as to achieve the effects of comfort, energy conservation and silence.
Correspondingly, in the heating mode, when the machine is started up, the upper air outlet 71 and the lower air outlet 72 can simultaneously output air, so that the rapid heating effect is ensured. And after the air conditioner stably operates, the upper air outlet 71 is closed, and only the lower air outlet 72 is used for air outlet. After reaching the preset temperature, the fan 2 runs at a lower rotating speed or stops running so as to achieve the effects of comfort, energy conservation and silence.
