Study on influence of the cavity wall heat transfer test in the hot summer and cold winter zone

The influence of the maintenance period to the wall of heat transfer coefficient has been analyzed. By comparing the result of cavity wall of heat transfer coefficient test and theoretical calculation, the reason of the differences between the two parts has been analyzed and the corrective measures to reduce the influencing factors in the cavity wall heat transfer coefficient experiment have been given, which provide a reference for the cavity wall research in the hot summer and cold winter zone.
