Description
Technical field
The present invention relates to be installed in the shutter on the window.
Background technology
Shutter is mounted in one of solar protection devices on the window, except that the fixed shutter of traditional louvre blade, has also occurred some in recent years and can regulate the adjustable shutter arrangement at louvre blade angle of inclination.These adjustable shutter arrangements are all through front and back pairings, at least two pairs of serial connection bands, form these louvre blades serial connections with the form of parallel-crank mechanism.Move up and down simultaneously the tandem connection band alternately; Just can regulate the angle of inclination of these louvre blades; And existing most adjustable shutter arrangements all can let louvre blade be adjusted to all to shelter from outside window light or let these louvre blades with light is parallel into indoor to let it shine outside window.All be adjusted at louvre blade and shelter from outside window under the light situation, this shutter can stop that (be mainly partial radiation and convection current transmit) heat of a part of sunshine imports into indoor.Yet existing these adjustable shutter arrangements have only only played the effect that stops a part of sunshine heat, all do not have to utilize the sunshine heat to regulate the function of interior temperature.
Summary of the invention
The objective of the invention is, provide a kind of adjustable sunshine heat that can utilize to regulate the phase-changing energy storage louver of interior temperature.
The technical scheme that realizes said purpose is a kind of like this phase-changing energy storage louver.The aspect identical with prior art be, it comprises some louvre blades, front and back pairing and at least two pairs of serial connection bands that are connected in series these louvre blades with the form of parallel-crank mechanism; And, moving up and down alternately under two kinds of situation that can not move again at the tandem connection band, these louvre blades all turn to and are all blocking the state of light outside window.Its improvements are that louvre blade of the present invention all is the middle double-deck shape that vacuum chamber is arranged, and is filled with the phase-change material of gas-liquid phase transition in its vacuum chamber; All being coated with on the external surface of one deck at these louvre blades fullly has the coating of high-absorbility to solar radiation, all is coated with the full coating that solar radiation is had high reflectance on the external surface of another layer.Each to the top of serial connection band all through a conveyer belt connection on the belt pulley.
Utilization of the present invention and adjustment process are following:
Daytime; There is two states: one, accumulation of heat state---when outdoor sunny; And interior temperature is not higher than most of people and feels pleasant temperature when (this case is called " comfort temperature ", for example 23 ℃～25 ℃), and the rotation through belt pulley drives the tandem connection band and does staggered up and down moving; Make a side that is coated with the full coating (hereinafter to be referred as " high-absorbility coating ") that solar radiation is had a high-absorbility on the louvre blade external surface towards outdoor, and make louvre blade vertical as far as possible with sunshine.Because the high-absorbility coating absorbed sunshine and was converted into heat this moment, so, this faces at louvre blade outside in, the phase-change material in its vacuum chamber is also at the sunlit heat of absorption, and then undergoes phase transition (being converted into gaseous state by liquid state) and accumulation of heat; Simultaneously, because louvre blade has certain opening angle, can too not influence indoor daylighting.Two, heat insulation or sunshade state---low and when not having the sun or interior temperature to be higher than comfort temperature when outside temperature; Then drive the tandem connection band and do staggered up and down moving through the rotating belt dish; Make a side that louvre blade is coated with the full coating (hereinafter to be referred as " highly reflective coatint ") that solar radiation is had a high reflectance outwardly; This moment, the interchange of heat of indoor and outdoor just more than the much less of existing shutter, also just reduced air conditioning energy consumption simultaneously like this owing to the high reflectance of louvre blade to outdoor radiation.
At night; There is two states equally: one, heat supply state---when outside temperature is lower than indoor comfort temperature and interior temperature and also is not higher than comfort temperature; Drive the tandem connection band through the rotating belt dish, a side that the high-absorbility coating is arranged to the louvre blade external surface is fully towards indoor.Because this moment, interior temperature was lower than the phase transition temperature of phase-change material, so the phase-change material in its vacuum chamber also undergoes phase transition (being converted into liquid state by gaseous state) and gradually to indoor heat release.Again since this moment all louvre blades one side of highly reflective coatint is arranged, be all towards outdoor, so, can reduce the heat transmission of indoor and outdoor, also just reduced air conditioning energy consumption certainly simultaneously.Two, radiating state---when phase-change material is entirely for gaseous state when interior temperature is higher than comfort temperature and in the louvre blade vacuum chamber; Then drive the tandem connection band through the rotating belt dish; A side that the high-absorbility coating is arranged to louvre blade is towards outdoor, through the outdoor heat radiation of radiation direction.
From scheme and utilization of the present invention and adjustment process, can find out; The present invention can effectively utilize solar energy (being the heat of sunshine); Be particularly useful for the bigger place of day and night temperature (such as some areas in Xinjiang; " early wear the fur-lined jacket noon and entry, eat watermelon round stove " king-sized phenomenon of the temperature difference is just arranged).Not only can make the interior length phase keep comfortable, also greatly reduce the consumption of other energy, not only energy-conservation but also environmental protection kills two birds with one stone.
