Description
技术领域technical field
本发明涉及传热系数检测技术领域，具体涉及一种传热系数检测加热装置及传热系数检测装置。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.
背景技术Background technique
墙体作为建筑围护结构的主要部分，墙体传热系数检测是重要的检测项目之一。墙体的传热系数K是表征墙体(含所有构造层次)在稳定传热条件下，当其两侧空气温差1K(1℃)时，单位时间内通过单位平方米墙体面积传递的热量。常规现场检测手段为热流计法，现场使用的加热手段为安装空调和油汀进行加热，或者在夏季单使用空调进行制冷。针对标准上的要求：维护结构高温侧表面温度应高于低温侧10℃以上，且在检测过程中任何时刻均不得等于或低于低温侧表面温度。日常检测中很难对空间加热或制冷保持10℃以上温差，尤其是在春秋季节，空调效果不好，或者需要加热的房间过大时，都很难满足要求，并且如果需要采用空调进行加热则需要现场搬运安装空调，操作不方便。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-temperature side of the maintenance structure should be higher than that of the low-temperature side by more than 10°C, and must not be equal to or lower than the surface temperature of the low-temperature side at any time during the detection process. It is difficult to maintain a temperature difference of more than 10°C for space heating or cooling in daily inspections, especially in spring and autumn, when the air-conditioning effect is not good, or when the room to be heated is too large, it is difficult to meet the requirements, and if it is necessary to use air-conditioning for heating The air conditioner needs to be transported and installed on site, which is inconvenient to operate.

A hot box heating device and an insulating layer are arranged on the inner wall of the box, the temperature sensor probe is covered in the hot box, and the hot box and the electric heater are connected with the control box. This existing technology is mainly based on the principle of "one-dimensional heat transfer" to detect the heat transfer coefficient. It is necessary to ensure that the temperature inside the hot box is consistent with the temperature outside the hot box, and there is no heat transfer between them. Therefore, it is necessary to heat the inside of the hot box. , It is also necessary to heat the indoor air. The standard of this detection method requires the detection time to be no less than 72 hours. The temperature difference between the box and the room is required to meet the average temperature difference during the test. The accuracy of the results has been affected to a certain extent, and the structure of this detector is complex and inconvenient for detection.

The monitoring probe collects the temperature in the box 1 and transmits it to the microcontroller. When the target temperature is greater than the temperature in the box 1, the microcontroller outputs heating to the thin film heater 2. command, when the target temperature is equal to the temperature in the box 1, the microcontroller outputs a command to stop heating to the thin film heater 2, and the microcontroller regularly sends the When the temperature collected by the monitoring probe is out of power or faulty, the GSM remote alarm will send a power outage message to the corresponding mobile phone number.
实施例2Example 2
本实施例为一种传热系数检测装置的具体实施方式，包括实施例1中提供的一种传热系数检测加热装置、热流计板、位于围护结构外表面的温度测试仪器。This embodiment is a specific implementation of a heat transfer coefficient detection device, including a heat transfer coefficient detection heating device provided in Embodiment 1, a heat flow meter plate, and a temperature testing instrument located on the outer surface of the enclosure.
检测时，将热流计板用胶带贴紧在箱体1内的维护结构的内表面上后，将箱体1通过实施例1中的方式固定到维护结构的内表面，箱体1内加热到目标温度后，分别记录围护结构内外的温度、围护结构内表面温度、外表面温度、热流计板的数值，根据传热系数公式计算出传热系数，记录多组数据求平均值。During detection, after the calorimeter plate is attached to the inner surface of the maintenance structure in the box body 1 with adhesive tape, the box body 1 is fixed to the inner surface of the maintenance structure by the method in embodiment 1, and the box body 1 is heated to After the target temperature, record the temperature inside and outside the envelope, the temperature of the inner surface of the envelope, the temperature of the outer surface, and the value of the heat flow meter plate, calculate the heat transfer coefficient according to the heat transfer coefficient formula, and record multiple sets of data to calculate the average value.
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。Apparently, the above-mentioned embodiments are only examples for clear description, rather than limiting the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the scope of protection of the present invention.
