Description
Technical Field
The utility model belongs to the technical field of the building energy conservation, in particular to thermal-insulated difference in temperature testing arrangement of building energy-saving coating.
Background
Building energy consumption is always a big household of energy consumption. With the continuous increase of the total area of buildings and the continuous improvement of the indoor living comfort level, the energy consumption of the buildings tends to increase sharply. In the energy consumption statistics, the energy consumption of the building is about 30% of the total social energy consumption calculated according to the energy consumed in the building and using processes, and if the energy consumed in the building material production process is added, the energy consumption accounts for 46.7% of the total social energy consumption. Therefore, building energy conservation has a significant impact on achieving the "dual carbon" goal, and enhancing the thermal insulation performance of a building envelope is almost a necessary way to achieve energy conservation and carbon reduction in all types of buildings.
At present, materials with building energy-saving functions mainly comprise three types: heat-blocking type, sunlight-reflecting type, and infrared radiation type. The materials applied to the building envelope structure are mainly the first two types, namely heat conduction blocking type materials represented by rock wool and polystyrene boards and sunlight reflecting type coatings represented by heat reflecting heat insulation coatings.
Wherein, the heat conduction blocking type material adopts the heat conduction coefficient to measure the energy-saving effect. For example, the heat conductivity coefficient of the rock wool is 0.037-0.043W/(mK), the heat conductivity coefficient of the polystyrene board is 0.033-0.039W/(mK), and the heat conductivity coefficient of the aerogel is 0.017-0.025W/(mK). Generally speaking, the lower the thermal conductivity of the material and the thicker the material is, the higher the thermal resistance is, the better the energy saving effect is, and the determination is mainly made according to GB/T10295-.
Sunlight reflective materials, represented by heat reflective insulating coatings, are mainly used on the outermost surfaces of buildings. The material can reflect the electromagnetic waves in a visible light region with the wavelength of 0.38-0.76 mu m and a near infrared light region with the wavelength of 0.76-2.5 mu m in the solar spectrum, so that the electromagnetic waves are not absorbed by equipment or buildings, and the temperature of the surface and the interior of the coated buildings is reduced. The higher the reflectivity of the coating to visible light and near infrared light, the more remarkable the heat insulation effect, and the determination is mainly carried out according to GB/T25261-2018 reflective heat insulation coating for buildings.
The infrared radiation type material is a novel building energy-saving material, and the heat inside the material is radiated to the external space in the form of electromagnetic waves by using a substance with high infrared emissivity, so that the effect of reducing the surface temperature of a building and achieving active refrigeration is achieved. The measurement of the emissivity of the material is originally from the radiation heat-insulating material of the spacecraft, and the normal emissivity of the infrared spectrum is taken as a measurement index. At present, various problems still exist in the application of the measurement technology in the field of civil materials, and the technology opening is limited to a certain extent. Therefore, for such materials, taking a radiation type coating as an example, people try to evaluate the energy saving effect by using the thermal insulation temperature difference mentioned in the standard of the existing thermal reflection thermal insulation coating and thermal insulation coating as an index, and if the value of the temperature difference is larger, the effect is better. The specific analysis is as follows:
the existing standards GB/T25261-2018 reflective insulation coating for buildings and T/CIE 082-2020 detection method of insulation temperature difference of thermal insulation coating relate to a test method of insulation temperature difference, and an artificial light source (a xenon lamp or a dysprosium lamp) is respectively used for simulating sunlight or circularly heating tertiary water as a stable heat source to measure the insulation temperature difference of one side of a coating of a detected material and one side of a back plate. The testing method can represent the heat preservation effect of the coating according to the measured temperature difference. However, since the temperature of the heat source is only a certain fixed value, and the temperature of the real environment fluctuates back and forth within a certain range, the energy saving effect of the coating in the real natural environment cannot be determined.
The standard T/CSTM 00292-2021 building heat insulation coating energy-saving evaluation method simulates an actual building by building a large test box (4 meters long, 3 meters wide and 2.6 meters high), coats the energy-saving coating on the outer surface of the building, monitors the gradual time values of the temperatures of the inner and outer surfaces of the test box body under outdoor all-season and all-weather natural conditions, and evaluates the effect of the heat insulation coating on the indoor temperature. The evaluation system of the detection method is more objective and representative, but has a plurality of problems: the method needs great investment for building a test platform for the early-stage experiment, and has high operation requirement and high detection difficulty.
