Building enclosure structure heat transfer coefficient rapid test device and test method thereof

The invention relates to a building enclosure structure heat transfer coefficient rapid test device and a test method thereof. A temperature control box is made of sandwich heat preservation color steel plates, the temperature control box is in a square shape, and an inner layer is in a cylinder shape; the inner layer of the temperature control box in a circular shape and is opened at one side; the inner surface of a tested enclosure structure is in tightly contact with one side of the circular opening of the temperature control box; a refrigerating/heating device is arranged in the temperature control box and connected with a control panel by a lead; a heat flowmeter and a temperature sensor are distributed on the inner surface of the tested enclosure structure; a temperature sensor is distributed in the corresponding position of the outer surface of the tested enclosure structure, and the outer surface of the tested enclosure structure is shielded by shading cloth; all the temperature sensors are connected
