Abstract

The utility model provides a porous medium solar energy heat collecting combined wall, which is characterized in that a porous medium layer is arranged between a transparency glass plate and a thermal storage wall; an air sealing sandwich layer is formed between the transparency glass plate and the porous medium layer; the porous medium layer, the thermal storage wall and an upper and a lower ventilating ports of the thermal storage wall form an air flow passage for supplying heat for a heating house. By daylight, sufficient solar radiation exists, and the porous medium layer quickly and effectively collects solar radiation energy and conducts heat; the porous medium layer supplies heat for the heating house by the air flow passage and the ventilating ports, and stores excess solar energy. At night, the solar radiation does not exist, the porous medium layer is used as a heat insulation body and releases self storing heat with the thermal storage wall. Thus, the heat dissipation and cooling influence of the heating house is counteracted and the insulating properties of the heating house are obviously enhanced. By tests, the solar utilization rate of the utility model can obtain 30%.

Description

Porous media formula solar energy heating faced wall

Technical field

The utility model relates to a kind of solar energy heating faced wall, particularly a kind of porous media formula solar energy heating faced wall.

Technical background

The solar energy heating faced wall of releasing (Trombe Michel wall) is the air blanketing that seals between solar radiant energy heating clear glass and the Heat Storing Wall outer surface by absorbing at present, because of greenhouse effect, temperature raises, and the air that is heated conducts heat to Heat Storing Wall in heat conducting mode.Thermal insulation layer is set a determining deviation place at interval at distance Heat Storing Wall inner surface, utilize the air flow channel that forms between thermal insulation layer and the accumulation of heat body of wall inner surface, make and be subjected to the conduction of Heat Storing Wall body heat and the air of temperature rise, enter in the heating chamber from the last ventilating opening of Heat Storing Wall and to heat, and air in the relatively low heating room of temperature, enter from the following ventilating opening of Heat Storing Wall and to be conducted by the Heat Storing Wall body heat and heat up, generate the natural convection loop of heating air-flow thus, constantly solar radiant energy collected, stored and to the heat supply of heating room.And when outdoor temperature is low,, prevent the contrary circulation of air-flow by closing ventilating opening under the air flow channel to night, and under the acting in conjunction of thermal insulation layer, increased the thermal resistance of heating room and external environment, the temperature after the heat radiation of counteracting Heat Storing Wall reduces the influence to the heating room, reduces heating room variations in temperature.Therefore, the solar energy heating faced wall is when absorbing solar radiant energy, owing to be subjected to the influence of Heat Storing Wall conduction efficiency, make that temperature rising speed in heating room is slower, and when heating at night chamber external environment temperature is low, air is easily passed to external environment condition by air flow channel and Heat Storing Wall with heat in the heating room, makes the heat insulating ability in heating room not reach people's re-set target yet.

Summary of the invention

The purpose of this utility model is to provide a kind of porous media formula solar energy heating faced wall, realizes daytime when abundant solar radiation is arranged, and the heat supply of heating room is collected and conducted to porous media with solar radiant energy rapidly, stores the solar radiant energy of " surplus " simultaneously; And when heating at night chamber external environment temperature is low, porous medium layer both can be used as thermal insulation layer, can be released into lentamente in the heating room with the heat of Heat Storing Wall again, offset the radiating and cooling influence in heating room, obviously improve the heat-insulating property in heating room self internal storage.

The utility model is to realize like this, between transparency glass plate and Heat Storing Wall, porous medium layer is set, make and form the occluded air interlayer between transparency glass plate and the porous medium layer, between porous medium layer and the Heat Storing Wall, and the upper and lower ventilating opening of Heat Storing Wall forms the air flow channel to the heating of heating room.When abundant solar radiation was arranged by day, porous medium layer was fast and effeciently collected solar radiant energy, heat conduction, gave the heating of heating room through air flow channel and ventilating opening, and stored the solar energy of " surplus ".When do not have solar radiation night, porous medium layer was as the heat-insulation and heat-preservation body, and and Heat Storing Wall together the heat of self storing is discharged, to offset the radiating and cooling influence in heating room, obviously improve the heat-insulating property in heating room.

Description of drawings

Fig. 1 is the structural representation of the utility model porous media formula solar energy heating faced wall.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Referring to Fig. 1,1 is porous medium layer, and 3 is transparency glass plate.Between porous medium layer 1 and transparency glass plate 3, be sealing air interlayer 2.5 is Heat Storing Wall, is that air flow channel 7,4 is the following ventilating opening that is arranged on Heat Storing Wall 5 between Heat Storing Wall and

porous medium layer

1, and 6 is last ventilating opening.When sufficient solar radiation was arranged by day, glass plate 3 absorbed solar radiant energies with air blanketing 2, and because of greenhouse effect, temperature raises.So, when the thermal conductive resin that porous medium layer 1 utilizes self conducts air in the heated air flow road 7 and Heat Storing Wall 5 with heat, the heat of " surplus " is stored, to reduce the influence that heating room " too much " is subjected to external environment condition.And the temperature rise air that is heated in the air flow channel 7, enter the heating room by last ventilating opening 6, the lower air of temperature in the heating room enters air flow channel 7 from following ventilating opening 4 and is heated rising, so going round and beginning again forms the Natural Circulation of heating air-flow, and the circulating current direction is shown in the hollow arrow among Fig. 1.The Natural Circulation of above-mentioned heating air-flow makes that air themperature raises rapidly in Heat Storing Wall 5 and the heating room.When night, heating room ambient temperature was low, because the heat-insulation and heat-preservation and the heat release of porous medium layer 1 and the heat release that is stored in Heat Storing Wall 5, common heat leakage of offsetting the heating room causes the influence of cooling, thereby the temperature of slowing down the heating room effectively reduces, and increases the comfort level in heating room.Through the reality test, the solar energy utilization ratio of porous media formula solar energy heating faced wall reaches 30%.

Beneficial effect

The release of the utility model porous media formula solar energy faced wall, when sufficient solar radiation is arranged, many The hole dielectric layer is stored carrier as heat conduction and heat, can promote rapidly the temperature in heating room, effectively alleviate heating The room is because of the too high phenomenon of heat " surplus " temperature, when night, heating room ambient temperature was low, and porous The heat-insulation and heat-preservation function of dielectric layer, and cause cooling with heat leakage that the common heat release of Heat Storing Wall is offset the heating room Impact, the temperature that effectively slows down the heating room reduces, and increases the comfort level in heating room. Through the reality test, The utility model porous media formula solar energy heating faced wall is taking full advantage of solar radiant energy, saves the energy, Satisfy thermic load requirement in the heating room, have fairly obvious superiority on the comfort level in increase heating room, it Solar energy utilization ratio can reach 30%.
