Description
Technical field
The utility model belongs to residential construction area, is related to a kind of wall made of phase change material structure more particularly to a kind of phase transformation
The adjustable wall made of phase change material structure of temperature, can be applied to civil buildings heating and air conditioner energy saving, greening building energy saving, passive type
The fields such as building energy conservation.
Background technique
The raising required with indoor thermal comfort is quicklyd increase with population, building energy consumption has obtained quick growth,
The 40% of global total energy consumption is accounted for, has accounted for 68% for warm energy consumption for cooling especially in building.Therefore, domestic and foreign scholars research and develop
Different energy-saving building technologies is to improve building energy utilization rate, reduce architecture indoor heating energy consumption.
Phase-change material is widely used in construction wall due to thermal storage density with higher, with realize the energy when
Between transfer, improve indoor thermal environment comfort.Current common methods are in wall-body energy saving, centre or outside using phase transformation material
Material.
When correlative study is shown near the phase-change material phase transition temperature applied to wall indoors mean temperature, wall
Hot property it is best.It is existing practical since one position of existing wall can only use a kind of phase-change material of phase transition temperature
The phase transition temperature of novel middle phase-change material is mostly chosen according to the average indoor temperature of summer or one of them season in winter.
However, since Summer Indoor mean temperature is apparently higher than winter, by a kind of phase transformation of phase transition temperature of one of Season select
Material can make phase-change material that can not play latent-heat storage and exothermic function in another season.For example, flat by Summer Indoor
When equal temperature selection phase-change material, the phenomenon that winter room temperature will appear always below phase transition temperature, phase-change material is always
Phase transition process is not present in solid；Conversely, Summer Indoor temperature can go out when selecting phase transition temperature by winter average indoor temperature
Now always above phase transition temperature the case where, phase-change material are liquid always, also do not occur phase transition phenomena.
There is also the building enclosure using two kinds of sizing phase-change material plates, such as Chinese patent applications in the prior art
CN201410825961.6 etc., by the way that the outer sizing PCM wall layer of fixed setting and default is respectively set on outer wall structure of building
Type PCM wall layer, the phase transition temperature of outer sizing PCM wall layer are higher than the phase transition temperature of interior sizing PCM wall layer.Outer sizing
PCM wall layer mainly plays a role in summer, when outer sizing PCM wall layer is substantially equal to or is higher than its phase transition temperature, outside
It is liquid that PCM wall layer of being formed gradually is melted by solid-state, and the heat of the outer solar radiation of absorption chamber reduces and enters the room room
Heat reduces the energy consumption of cold supply system to reduce room temperature.Interior sizing PCM wall layer mainly plays a role in winter,
When interior sizing PCM wall layer temperature be substantially equal to or be higher than its phase transition temperature when, internal layer be formed PCM wall layer by solid-state gradually
Melting is liquid, extra heat in absorption chamber.Set up separately by using the sizing phase-change material layer of different characteristics in external wall
Inside and outside, peak load shifting can be achieved in the load for building cooling supply or heating, effectively reduces fluctuations in indoor temperature, shows simultaneously
Writing reduces whole energy consumption.Although the above-mentioned prior art has its own a technological merit, its shortcoming also clearly,
It is mainly manifested in the inside and outside sizing PCM wall layer with different phase transition temperatures, the two is fixed on wall, two kinds of phases
Become wallboard layer and play latent heat of phase change accumulation of heat and exothermic effects and be also concentrated mainly on a season, a kind of PCM wall layer plays a role
When, another PCM wall layer does not play accumulation of heat and exothermic function substantially.
