Title:
DEVICE FOR MEASURING RADIANT COOLING PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2021/020707
Kind Code:
A1
Abstract:
A device for measuring radiant cooling performance according to the present invention disclosed herein comprises: a first simulation unit which simulates light toward a sample that can be radiant-cooled; a second simulation unit which faces the first simulation unit with the sample therebetween and simulates an outdoor environment; and a measurement unit which measures the temperature of the sample that is radiant-cooled toward the second simulation unit. The second simulation unit includes: an isolated vacuum chamber part in which the sample is provided; and a cooling part which is provided on one side of the chamber part so as to face the first simulation unit with the sample therebetween, absorbs radiant heat energy radiated from the sample, and provides an environment cooled by a coolant. According to the configuration described above, the device is not affected by the outside environment, thus enabling accurate and consistent measurement of radiant cooling performance.
