Buildings environmental simulation experimental system
Technical field
The present invention relates to a kind of buildings environmental simulation experimental system, also relate to and use above-mentioned buildings environmental simulation experimental system to carry out the method that coefficient of heat conductivity detects.
Background technology
In construction work, the heat-proof quality of building outer wall material more and more comes into one's own, and it directly has influence on the energy-conserving and environment-protective that buildings uses, but always is difficult point for the detection of the coefficient of heat conductivity of exterior wall.At present many methods that is employed in outer wall material both sides setting different temperatures are carried out the detection of coefficient of heat conductivity; But thermal energy conduction is except receiving temperature difference influence; How the humidity of environment, wind-force and heat energy are transmitted to the detection numerical value that all has influence on coefficient of heat conductivity on the exterior wall, so the traditional measurement mode can't satisfy accurate detection demand.
Summary of the invention
Technical matters to be solved by this invention provide a kind of can be through the buildings environmental simulation experimental system that building internal and external environment simulation back is accurately detected the coefficient of heat conductivity of body of wall.The present invention also provides a kind of and has adopted above-mentioned buildings environmental simulation experimental system to carry out the method that the materials for wall coefficient of heat conductivity detects.
For this reason; Buildings environmental simulation experimental system provided by the invention comprises experiment with partition wall, partition wall space, the separated left side and space, the right, wherein is provided with convertible frequency air-conditioner in the space, the right and is used for normal temperature indoor humidity environment constant in the simulating chamber; The right also is provided with light fixture simulating chamber intraoral illumination in the space; Space, the left side is provided with dryer, well heater, hair-dryer and humidifier, and space, the left side one side of partition wall is provided with heat flow meter, and the partition wall both sides are provided with temperature sensor; Temperature sensor all is connected with central processing unit with heat flow meter, and central processing unit is connected with display.
The present invention also provides and has adopted above-mentioned buildings environmental simulation experimental system to carry out the method that the materials for wall coefficient of heat conductivity detects, and comprises 1, through convertible frequency air-conditioner constant normal temperature temperature is kept in space, the right, through the opening and closing simulation lighting condition of light fixture; 2, through controlling simulation all-environment temperature, humidity and wind condition in dryer, well heater, hair-dryer and the humidifier on the left side space; 3, above-mentioned environment is kept after a period of time the temperature data that temperature sensor and heat flow meter through being arranged on the partition wall both sides are monitored day part in real time; The data in real time that temperature sensor and heat flow meter are measured is sent to central processing unit; After central processing unit is handled, form the coefficient of heat conductivity data of partition wall, and this data delivery is carried out screen display to display.
Because in the buildings environmental simulation experimental system provided by the invention; The partition wall the right and left that is used for simulant building beyond the region of objective existence wall all is modeled into indoor and indoor environment through various device; The operator only need control equipment such as dryer, well heater, hair-dryer and humidifier can simulate required outdoor environmental index; And the indoor environment index only needs to simulate through controlling convertible frequency air-conditioner and light fixture; Therefore it is accurately higher under the environment that this comparatively accurately simulation is come out, to detect the coefficient of heat conductivity that obtains, and relatively can reflect the actual performance of material.

Embodiment
As shown in Figure 1; Buildings environmental simulation experimental system provided by the invention comprises experiment with partition wall 1, space 2, the partition wall 1 separated left side and space, the right 3, wherein is provided with convertible frequency air-conditioner 4 in the space 3, the right and is used for normal temperature indoor humidity environment constant in the simulating chamber; The right also is provided with light fixture simulating chamber intraoral illumination in the space 3; Be provided with dryer 5, well heater 6, hair-dryer 7 and humidifier 8 in the space, the left side 2, space, the left side 2 one sides of partition wall 1 are provided with heat flow meter, and partition wall 1 both sides are provided with temperature sensor; Temperature sensor all is connected with central processing unit with heat flow meter, and central processing unit is connected with display.In the present embodiment, directly blow to for fear of air-conditioning and to cause local temperature low excessively on the partition wall 1, influence detects the degree of accuracy of data, closes on partition wall 1 in the space, the right 3 and is provided with first curtain 9; Cause heating up too fast for fear of adding hot charging device direct radiation partition wall 1, close on partition wall 1 in the space, the left side and be provided with second curtain 10.
The present invention also provides and has adopted above-mentioned buildings environmental simulation experimental system to carry out the method that the materials for wall coefficient of heat conductivity detects, and comprises 1, through convertible frequency air-conditioner 4 constant normal temperature temperature is kept in space, the right 3, through the opening and closing simulation lighting condition of light fixture; 2, through controlling simulation all-environment temperature, humidity and wind condition in dryer 5, well heater 6, hair-dryer 7 and the humidifier 8 on the left side spaces 2; 3, above-mentioned environment is kept after a period of time the temperature data that temperature sensor and heat flow meter through being arranged on partition wall 1 both sides are monitored day part in real time; The data in real time that temperature sensor and heat flow meter are measured is sent to central processing unit;, central processing unit forms the coefficient of heat conductivity data of partition wall after handling; Can preestablish computing formula in the present embodiment and directly calculate coefficient of heat conductivity, and this data delivery is carried out screen display to display.
