Description
Technical field
The invention belongs to energy-saving building technology fields, are related to a kind of phase-change heat collecting and storing wall device and the sun using reduced scale
Room test room, and solar simulator device and external environment case is combined to be used for the experimental system of solar energy housing experimental study.
Background technique
The northern area of China is more cold, is the main region of heating, wherein northern cities and towns heating energy consumption is 1.84 hundred million
Tce accounts for the 21% of building energy consumption, reduces building heating energy consumption and is of great significance for building energy conservation.Northern area solar energy
It is resourceful, if the thermal isolation and heat storage performance of architectural exterior-protecting construction can be reinforced, and it efficiently can be carried out heating using the sun and can effectively change
Kind indoor thermal environment, reduces heating energy consumption.Heat collecting and accumulating wall is a kind of widely used solar heating mode, but is often adopted
It is sensible heat accumulation of heat, in order to improve the heat storage capacity of wall, the preferable phase-change material of heat storage performance can be used.Phase transformation thermal-arrest stores
Hot wall is remarkably improved its heat storage performance, greatly improves its heating efficiency, significantly improves winter indoor thermal environment of building.Phase transformation collection
The construction ecto-entad of thermal regenerator wall be followed successively by glass cover-plate, air interlayer, phase-change material layers, adiabator layer, structure sheaf and
Interior finish coat.The nonlinear change of the hot physical property of phase-change material under the conditions of outside air temperature, solar radiation cyclically-varying, so that
It conducts heat different from traditional heat collecting and accumulating wall, needs the heat-transfer mechanism for probing into phase-change heat collecting and storing wall and phase-change heat collecting and storing wall
The hot property and its Thermal Design method of formula solar energy housing difference component.The research method of passive solar house be divided into theory analysis,
Experiment test and numerical simulation are asked wherein experiment test is a kind of important research means particularly with mathematical physics is complicated
Topic, experiment test are more effective.Experiment testing research is divided into on-the-spot test research and experimental study.On-the-spot test is divided into long-term prison
It surveys and short-term close mapping, the purpose of long term monitoring is to understand the synthesis thermal characteristics and energy conservation effect of solar energy housing in normal conditions of use
Fruit is convenient for technical and economic evaluation；The purpose of short-term close mapping is to study the actual performance of passive heat-collection and heat-accumulation component, is understood too
The heat transfer coefficient of positive room building enclosure is checked to calculate Thermal Design.On-the-spot test needs to build practical building, this
A large amount of human and material resources, financial resources are spent, and are taken a long time.On-the-spot test simultaneously is affected by outdoor weather condition, only
It can be tested under the conditions of specific period and particular weather.And it is uncontrollable due to the complexity of outdoor environment and condition
Property, it is difficult to the analysis of single influence factor is carried out, the affecting laws of different parameters cannot be intuitively disclosed, experimental repeatability is poor.It is real
The test room that research mostly uses reduced scale is tested, saving of labor easily builds, and the cost and manpower of construction is greatly saved.Experimental study is divided into reality
Test room experiment under the weather conditions of border is tested with the controllable test room of environmental condition.And the design about test room,
Then size is different, and experimental result differs greatly.The structure design of test room is relatively fixed single simultaneously, is only capable of probing into certain
The influence of a little elements, experimental study have significant limitation.And for the environmental Kuznets Curves of experimental system, most experimental system institute
The radiating light source spectral characteristic of use differs greatly with the practical sun, while intensity of solar radiation cannot continuously adjust, sun spoke
The uniformity penetrated is difficult to ensure.
Specifically, heat collecting and accumulating wall type solar energy housing experimental system is primarily present following some problems:

Design should defer to certain principle, as accumulation of heat wall-body energy saving should meet on large space Natural Convection Conditions and unit collector area
Room thermic load phase undertaken etc..
(2) design of test room structure is single, and research range is limited.
The structure design of test room is relatively fixed single, and glass cover-plate, accumulation of heat wall and space enclosing structure material cannot be into
Row replacement, air interlayer thickness etc. cannot be adjusted, to seriously hinder the research of different component hot propertys, hinders not
With the research of design parameter affecting laws, research range is limited.
(3) radiating light source spectral characteristic differs greatly with the practical sun, not can accurately reflect the influence of practical solar radiation.
The radiating light source of test room mostly uses greatly tungsten halogen lamp, xenon lamp etc., and the spectral distribution curve of these light sources transmitting
It differs greatly with the practical sun, cannot really reflect practical solar radiation, and the stability of light source is poor.
(4) intensity of solar radiation adjustable range is limited, and solar radiation uniformity is difficult to ensure.
The solar simulator device that test room uses only is adjustable the intensity of solar radiation of several fixations, cannot be to the sun
Radiation intensity is continuously adjusted, and adjustable range is limited.Simultaneously light source position and arrangement it is relatively fixed, solar radiation it is uniform
Property is difficult to ensure.
Based on the above reasons, should being precisely controlled from environmental condition, the rational design of system dimension, structure flexibly set
Meter etc. is improved.The present invention is improved for solar simulator device and phase-change heat collecting and storing wall device, to too
Positive room test room is optimized.Compared with conventional heat collecting and accumulating wall experimental system, the experiment for having widened solar energy housing significantly is ground
Study carefully range, improves the feasibility of solar energy housing experimental study.
