SYA-75 Transmittance Enclosure Solar Heat Gain Coefficient Tester

Based on the principle of steady-state heat transfer, an artificial light source is used within a thermal chamber to simulate solar radiation, and a transmittance calorimeter measures the solar heat gain inside the chamber. The ratio of this solar heat gain to the incident solar irradiance on the specimen’s surface yields the solar heat gain coefficient of the transparent envelope component.

SYA-75 Transmittance Enclosure Solar Heat Gain Coefficient Tester

Description

Product Introduction:

Based on the principle of steady-state heat transfer, an artificial light source is used within a thermal chamber to simulate solar radiation, and a transmittance calorimeter measures the solar heat gain inside the chamber. The ratio of this solar heat gain to the incident solar irradiance on the specimen’s surface is defined as the solar heat gain coefficient of the transparent envelope component.

Product Features:

1. The insulated cabinet, assembled using polyurethane foam technology, features a low thermal conductivity, excellent insulation performance, and energy efficiency.

Product Features:

2. Data acquisition and control are performed using a dedicated industrial computer.

3. Imported long-arc xenon lamp solar simulator with a collimated beam and a constant-current control cabinet, ensuring stable and uniform light irradiance.

4. A heat‑gain metering device for the cold chamber air ensures the accuracy of test results;

5. Imported high-precision digital temperature sensor with a resolution of 0.01°C;

6. The cold, hot, and protective chambers all employ PID control, ensuring precise temperature regulation and rapid response times.
