Solid wall radiation convection air conditioner capable of using air film for heat exchange

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...

AI Technical Summary

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
