Description

Technical Field

[0001] This utility model relates to the field of building energy conservation testing technology, specifically to a testing device for the solar heat gain coefficient of existing light-transmitting building envelope glass. Background Technology

[0002] Solar heat strikes the surface of a translucent building envelope, and the heat travels in three directions: reflected to the outside, absorbed by the glass, and transmitted into the interior through the glass. For different types of glass, the solar heat gain coefficient can be determined by analyzing the spectrum transmitted through the glass. Traditional testing methods typically involve applying a light source to one side of the glass, while a detector on the other side receives the light signal, converts it into an electrical signal, and transmits it to a main computer for data processing. The main computer then processes and analyzes the signal to obtain the solar heat gain coefficient of the test specimen.

[0003] The shortcomings of existing technology:

[0004] 1. Cumbersome testing process: Traditional testing equipment is usually large in size, and the installation and debugging process is complicated. It requires professional personnel to operate, making it difficult to conduct testing quickly and conveniently on existing building sites.

[0005] 2. Poor adaptability to different types of glass: For different types of glass, especially ordinary insulated glass, the light source and detector of traditional testing equipment may not be able to accurately match the characteristics of the glass, resulting in insufficient accuracy of the test results.

[0006] 3. Lack of rapid on-site testing capabilities: Existing technologies are insufficient to quickly determine the solar heat gain coefficient of glass on-site, failing to meet the needs of on-site assessment and renovation decisions.

[0007] 4. High requirements for the testing environment: Traditional testing methods have high requirements for the testing environment and require a strict laboratory environment. However, the environmental conditions at actual construction sites are complex and diverse, making it difficult to meet the requirements of traditional testing methods.

[0008] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0079] The principle of this utility model is as follows:

[0080] This invention is based on the optical transmission-absorption principle. It simulates the emission of a specific spectrum from a solar source, which penetrates the glass under test. The transmitted light signal is collected by a receiver, and the solar heat gain coefficient (SHGC) of the glass is calculated in real time by a data processing system. Its core workflow is as follows:

[0081] Optical path simulation and signal acquisition

[0082] Light source emission: The light source emitter 31 emits broadband visible light (simulating the solar spectrum). The beam is incident perpendicularly on the surface of the specimen 4. Part of the light is reflected or absorbed by the glass, and the remaining light passes through the glass and enters the receiver.

[0083] Transmitted light reception: The light source receiver 33 is attached to the other side of the specimen 4 to collect the spectral energy distribution (wavelength-intensity data) of the transmitted light in real time and convert it into an electrical signal.

[0084] Dynamic adjustment and calibration

[0085] Clamp self-adaptation: By linking the slide rail 32 with the pulley 334, the position of the light source receiver 33 is adjusted to ensure that the light source and receiver are in close contact with glass specimens 4 of different thicknesses, thus eliminating optical path gap errors.

[0086] Environmental compensation: The built-in algorithm of the data acquisition unit 1 automatically deducts ambient stray light interference and calibrates to standard test conditions (such as AM1.5 solar spectrum).

[0087] Data processing and SHGC calculation

[0088] Spectral analysis: The main unit 11 integrates the transmission spectrum and, combined with the spectral transmittance (τ), absorptivity (α), and secondary heat transfer coefficient of the glass, directly outputs the solar heat gain coefficient (SHGC) according to standard formulas (such as ISO9050).

[0089] Results output: Display screen 12 shows the SHGC value in real time, and the data can be exported for building energy efficiency assessment.

[0090] On-site adaptation mechanism

[0091] Rapid deployment: Glass can be directly clamped at the existing curtain wall opening sash using the detachable specimen clamp 3 and data cable 2, without the need to remove components, thus meeting on-site testing conditions (such as power supply and operating space).

[0092] Key technical points:

[0093] Integrated optical path design: The light source and receiver are coaxially aligned, avoiding the complex debugging of traditional separate equipment.

[0094] Dynamic sliding rail adjustment: compatible with 3-40mm thick insulated glass, solving the problem of glass specification differences in existing buildings.

[0095] Real-time algorithm compensation: Eliminates the influence of ambient light fluctuations, ensuring a test accuracy of ±3%, in line with GB / T2680 standard requirements.

[0096] Based on the above principles, this utility model enables on-site, rapid, non-destructive, and high-precision testing of the solar heat gain coefficient of existing light-transmitting building envelope glass.
