Technical Field

The invention belongs to the technical field of heat transfer of building enclosures, and particularly relates to a novel field detection device for a heat transfer coefficient of a building enclosure.

Background

The heat transfer coefficient of the enclosure structure refers to the heat transferred by the area of one square meter in one second under the condition of stable heat transfer, wherein the temperature difference of air at two sides of the enclosure structure is one degree, and the unit is tile/(square meter DEG). The heat transfer coefficient is not only material dependent but also process specific. The heat transfer coefficient is conventionally referred to as the overall heat transfer coefficient. The national current standard specification is not necessarily named as heat transfer coefficient. When the temperature difference in the heat transfer process is constant, the larger the heat transfer coefficient is, the higher the heat transfer rate of the heat exchanger is. While reducing any of the thermal resistances increases the heat transfer coefficient, the heat transfer coefficient will depend primarily on the thermal resistance of this control term when one is much higher than the others. The wall thermal resistance is usually small and negligible. The scale layer can generate considerable thermal resistance, so the heat transfer surface of the heat exchanger needs to be cleaned regularly. When the heat exchanger is designed, the thermal resistance of the control item needs to be accurately determined. When considering the intensified heat transfer process, it is first sought to reduce the thermal resistance of the control item. The heat transfer coefficient K of the wall body is characterized in that when the air temperature difference between two sides of the wall body (including all structural layers) is 1K (1 ℃) under the condition of stable heat transfer, the heat transferred by the area of the wall body per unit square meter in unit time is W/(M2. K). Namely, the heat transfer coefficient K includes all structural layers and air boundary layers on two sides of the wall. The method represents the thermal performance of a wall heat-insulating system, and researches show that the reduction of the heat transfer coefficient of the outer wall can obviously reduce the energy consumption of the building.

When the existing building envelope heat transfer coefficient field detection device is used, due to the fact that the existing building envelope heat transfer coefficient field detection device is too large in size and inconvenient to carry, and the problem that a connecting line is pulled and damaged from a side-view terminal due to walking during use can occur, and therefore the novel building envelope heat transfer coefficient field detection device is provided.
