Description
Technical field
The present invention relates to the energy-conserving and environment-protective building field, particularly a kind of full passive type solar energy air heat wall.
Background technology
More and more under the serious situation, pursue environmental protection and the energy-conservation target that becomes various countries, the whole world gradually at problem of environmental pollution that traditional energy consumption at present causes, Green environmental-protection building is wherein important field.A kind of technical application has appearred at present; Promptly utilize the atural beat radiation of solar energy and the greenhouse effect of glass (greenhouse effect: sun heat radiation can penetrate glass but the room temperature heat radiation can't escape out); In a window wall interlayer body, concentrate circumference low ambient temperature air; The upwards heat buoyancy that is caused by the temperature difference guides the air inflow after heating indoor naturally, thereby carries out indoor heating.The structural representation of this glass body of wall as shown in Figure 1, said heating body of wall comprises the hot air outlet 10 of body of wall inside upper part, it can communicate or be connected with air-conditioning or hot water system with indoor; Inboard heat absorption surface 18, it can be the building wall
Body or high reflecting glass; The high glass 16 that passes through of exterior wall, the outdoor air that is arranged at the exterior wall bottom enters the mouth 14; In addition, also can comprise the room air inlet 12 that the body of wall lower inside is provided with.This glass heats body of wall refluxes because outer cold glass can cause the decline air, thereby reduces the total air outflow that makes progress in the window wall interlayer body, and the heat convection current can not fully be carried out; In addition, air can meet with bigger resistance at the momentum of outdoor air entrance owing to turning to, thereby can reduce air mass flow, also can influence the exchange heat effect of indoor and outdoor air-flow.If overcome the problems referred to above, need to increase other machinery and therrmodynamic system; In addition, the restriction of the floor height that this design can be built, applicable situation is limited.
Summary of the invention
For solving prior art problems; The present invention proposes a kind of full passive type solar energy air heat wall; It makes full use of the atural beat radiation of solar energy and the greenhouse effect of glass; In a specially designed window wall interlayer body, concentrate circumference low ambient temperature air, the upwards heat buoyancy that is caused by the temperature difference guides the air inflow after heating indoor naturally, need not any machinery and therrmodynamic system and just can realize the natural heating to indoor environment.
For reaching the object of the invention, solar air heating pad wall of the present invention comprises the hot air outlet that is arranged at the body of wall inside upper part, and it can communicate or be connected with air-conditioning or hot water system with indoor; Inboard heat absorption surface, it can be construction wall or high reflecting glass; The high glass that passes through of exterior wall, its first half is provided with a plurality of distributed heat absorption Internal baffles, and Lower Half is provided with a plurality of distributed little
Air intake; In addition, also comprise body of wall top and bottom, it can pass through glass for height.
Preferred in addition, also can comprise the room air inlet that the body of wall lower inside is provided with.
Wherein, The effect of said a plurality of distributed Internal baffles is; Because outer cold glass can cause the decline air and reflux, thus the total air outflow that makes progress in the minimizing window wall interlayer body, and distributed little Internal baffle can destroy this backflow; Reduce the air velocity on cold glass inner side surface simultaneously, reduce external heat convection losses.
Momentum in the entrance cause air mass flow to reduce owing to turn to meeting to meet with bigger resistance thereby a plurality of distributed little air intakes can reduce air, increases air mass flow, destroys downward cold air sedimentation simultaneously, reduces thermal convection losses.In addition, it can also more effectively and equably be delivered to inboard hot surface and heat being heated cold air.
Solar energy heating wall of the present invention passive type work entirely need not any machinery and therrmodynamic system; Can be used in during application on the building of various floor heights, system can repeat to prolong about up and down; Can be used as independently heating system, also can be used in combination with other system; Whole system does not have moving-member, has guaranteed lowlyer, even is zero maintenance cost and need not special constructional materials that cost is lower.
