Problems solved by technology

It can conveniently lower the indoor temperature and control the humidity, but the indoor temperature distribution of this air conditioning method is uneven, the difference between cold and hot near the tuyere is obvious, and the cold wind feeling in the direction of the incoming flow is strong
[0005] 2. In winter, the air treated by traditional air-conditioning bears the heat load in the room, and the heat provided can match the heat load in the room. However, this air-conditioning method is easy to cause the indoor to be hot at the top and cool at the bottom, and the temperature gradient is excessive. Large, with a strong sense of blowing in the direction of the incoming air near the tuyere, you need to rely on a humidifier to adjust the indoor humidity
However, the heat exchanged is radiant heat and has strong directionality, so it needs to be combined with the fresh air auxiliary system
[0010] 3. A single cold (hot) radiation wall can only cool down the indoor enclosure structure and human body through radiation, and the cooling effect on the indoor air is not obvious

Embodiment 1

[0026] Such as figure 1 As shown, the solid-wall radiant convection air conditioner using air film heat exchange includes a guide body 1 , an air inlet tube 2 and a radiant plate 3 . The guide body 1 is a columnar body with a parabolic cross-section, with an arc-shaped guide surface 11 at one end and a Coanda curved surface 12 at the other end. There is a smooth transition between the arc-shaped guide surface 11 and the Coanda curved surface 12 . One end of the air inlet cylinder 2 is provided with an air inlet 21, and the other end is provided with an air outlet, which is located at one end of the arc-shaped guide surface 11 of the guide body 1, and the arc-shaped guide surface 11 of the guide body 1 is incorporated into the air guide body 1 through the air outlet 21. Its inner cavity forms a strip-shaped air outlet 4 between the air outlet and the guide body 1 . The radiation plate 3 is arranged at one end of the Coanda curved surface 12 of the guide body 1 , and the front ...

Embodiment 2

[0031] Such as figure 2 As shown, the only difference between this embodiment and embodiment 1 is that it also includes a cross-flow fan 6 and a surface cooler 7 arranged in the inner cavity of the air inlet tube 2 . The cross-flow fan 6 is installed in the inner cavity of the air inlet tube 2 near the air outlet, and the surface cooler 7 is installed in the inner cavity of the air inlet tube 2 near the air inlet 21 .

[0032] Briefly describe the application of the present invention:

[0033] The present invention is fixedly installed on the indoor ceiling by base plate 5. In Embodiment 1, the air inlet 21 of the air inlet cylinder 2 can communicate with the air outlet of the central air conditioner, which belongs to the air conditioner terminal device. Embodiment 2 can be used alone as a refrigeration air conditioner.

[0034] Briefly describe the working principle of the present invention:

[0035] Under summer conditions, the present invention blows out the air that r...

Abstract

The invention discloses a solid wall radiation convection air conditioner capable of using an air film for heat exchange. The air conditioner comprises a flow deflector, an air inlet cylinder and a radiation plate; the section of the flow deflector is a parabola-shaped columnar body, an arc flow guide face is arranged at one end of the flow deflector, a Coanda curve face is arranged at the other end of the flow deflector, an air inlet is formed in one end of the air inlet cylinder, an air outlet is formed in the other end of the air inlet cylinder, the air inlet cylinder is arranged at one endof the arc flow guide face of the flow deflector, through the air outlet, the arc flow guide face of the flow deflector is contained in an inner cavity of the air inlet cylinder, and a strip-shaped air outlet is formed between the air outlet and the flow deflector; the radiation plate is arranged at one end of the Coanda curve face of the flow deflector. The air conditioner has the beneficial effects that the no strong blowing feeling exists, and the hot comfort is good.

Description

technical field [0001] The present invention relates to a radiation convection air conditioner, in particular to a solid wall radiation convection air conditioner utilizing air film for heat exchange, specifically a radiation wall formed by cooling (or heating) a solid wall by an air film, and at the same time forming air convection indoors Air conditioner terminal unit. Background technique [0002] The traditional air conditioner, represented by the all-air system, conducts convective heat exchange with people, which conducts convective heat exchange with the surrounding environment through the cold (hot) air sent out. [0003] Traditional air conditioners have the following shortcomings in actual use: [0004] 1. In summer, traditional air conditioners centrally process the air, and use the treated air to bear the indoor cooling load. The cooling capacity can be well matched with the indoor cooling load of the room. It can conveniently lower the indoor temperature and c...
