Double Skin

An actual office building with ventilated double-skin facade (VDSF) in cold region has been studied for researching the opening or closing performance of VDSF on the airflow window in winter. In the daytime of winter, airflow window of external facade should be closed, and airflow window of internal facade should be open, according to which the indoor temperature can be kept at a comfortable level effectively, and the purpose of reducing the indoor thermal load and the building energy consumption of air conditioning can be reached. The research also provides the best time of the airflow window of internal facade to open and close. If one directly applies the analysis of experimental results to guide the construction of VDSF and other energy-saving design of buildings, it can provide a reliable reference for similar projects.

In order to satisfy the requirement of villages indoor thermal amenity in winter in cold district in north of china, thermal performance of level, vertical flue smoke organization form hot wall have been tested. The experiment use Testo flue gas analyzer, BES-C portable computer multi-channel data acquisition instrument, the infrared thermography and so on to acquire basic data of two type flue layouts hot wall. These parameters include smoke composition, the inport and export smoke temperature, smoke quantity, metope temperature of hot wall and so on. And then record the test data, calculate evaluation index of the thermal performance, which are metope temperature standard deviation, thermal inertia and heat efficiency, etc. According to the value of the heat efficiency, we can judge the thermal performance of two kind of hot walls. The test results shows that the heat efficiency of level flue smoke organization form is 68.9%, and the heat efficiency of vertical flue smoke organization form is 62.1%. The heat efficiency of hot wall in the form of level flue is higher, better meet the requirement of heating facilities in energy saving, residents thermal amenity.
