Abstract

The invention provides a heat transfer coefficient detection heating device and a heat transfer coefficient detection device. The heat transfer coefficient detection heating device comprises a box anda heating device, wherein the box comprises a box body and a cavity; the cavity is formed in the box body; the opening end of the box body is in sealed connection with the inner surface of a to-be-detected enclosure structure; the heating device is arranged in the box. The heat transfer coefficient detection heating device has the advantages that when the heat transfer coefficient of the enclosure structure of a building is detected by a heat flow meter, the opening end of the box body is in sealed connection with the inner surface of the to-be-detected enclosure structure, the interior of the box is heated by the heating device, the temperature in the box is 10 DEG C higher than the temperature of the outer side of the enclosure structure, and then the heat transfer coefficient can be detected; the structure is simple, the handling of air conditioners at site is not needed, the working efficiency is greatly improved, the indoor heating is also not needed, the operation is simple, andthe heat transfer coefficient can be detected in all seasons.

Description

technical field [0001] The invention relates to the technical field of heat transfer coefficient detection, in particular to a heat transfer coefficient detection heating device and a heat transfer coefficient detection device. Background technique [0002] The wall is the main part of the building envelope, and the detection of the wall heat transfer coefficient is one of the important detection items. The heat transfer coefficient K of the wall is the heat transferred through the wall area per square meter per unit time when the wall (including all structural layers) is under stable heat transfer conditions when the air temperature difference on both sides is 1K (1°C). . The conventional on-site detection method is the heat flow meter method, and the heating method used on site is to install air conditioners and oil heaters for heating, or use air conditioners for cooling in summer. According to the requirements of the standard: the surface temperature of the high-temper...
