Abstract
The invention discloses a guarding hot box for detecting thermal performances of walls. The guarding hot box comprises a measuring box, a protective box, a cold box and a test piece frame, wherein a test piece for isolating the cold box and the protective box is arranged in the test piece frame; the cold box and the protective box are respectively installed and arranged on the two sides of the interior of the test piece frame; the measuring box is mounted in the protective box; and the measuring box and the protective box are respectively sealed with the test piece frame. The shell of the protective box is made from the sandwich panel of an extruded sheet. The cold box is made from an argon arc welding integral stainless steel tank and a transformed steel plate on the outer surface. The guarding hot box disclosed by the invention has the advantages of being accurate in detection and reasonable in structure.
Description
Technical field
The invention belongs to technical field of buildings, refer more particularly to the protective hot box detecting thermal characteristic of wall.
Background technology
The method of domestic detection thermal characteristic of wall has 4 kinds, is respectively heat flow meter method, Heat-box method, hot case-heat flow meter method, a plane heat source method with constant heat rate and thermal infrared imager method.Wherein, Heat-box method comprises again protective hot box method and demarcates Heat-box method.Protective hot box method Cleaning Principle is based on one-dimensional steady-state heat transfer, required temperature, wind speed and radiation condition is set up respectively in test specimen both sides, these conditions are provided by hot case and ice chest respectively, after wall heat transfer reaches steady state (SS), measure air themperature and casing flow guiding screen surface temperature in surface of test piece temperature, casing and be input to the power of batch meter, by calculating the heat transfer coefficient of trying to achieve test specimen.Protective hot box is absolutely necessary one of equipment.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of protective hot box detecting thermal characteristic of wall, has and detects advantage accurate, rational in infrastructure.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
