Description
技术领域technical field
本实用新型涉及房屋结构环境的检测，具体涉及到一种室内结露检测装置，属于建筑技术领域。The utility model relates to the detection of the structural environment of houses, in particular to an indoor dew condensation detection device, which belongs to the technical field of buildings.
背景技术Background technique
在日常生活中我们可以看到，到夜间空气温度降低时，空气中的水分会有一部分析出，形成露水或霜。这是因为，自然界的空气中都含有一定量的水蒸气，在一定的气压条件下，空气中所含水蒸气与温度有关，温度越高，其可容纳的水蒸气越多。但相对每一温度，都有一个饱和值，超过这个饱和值，水蒸气就产生凝结，变为液态水。这个饱和值所对应的温度，即空气中的水蒸气开始出现凝结的温度，称之为露点温度，或叫作“露点”。露点温度与环境气氛含水量的关系是一一对应关系，即每一个露点温度对应环境气氛的一个含水量值，反之亦然。露点可以简单地理解为使气体中水蒸汽含量达到饱和状态的温度，或者说是湿度为100％时的环境温度。当空气中水蒸气含量不变的情况下，温度的降低能够使空气中原来未达饱和的水蒸气可以变成饱和蒸气，多余的水分就会析出，即出现结露现象。In our daily life, we can see that when the air temperature drops at night, part of the moisture in the air will be separated out to form dew or frost. This is because the air in nature contains a certain amount of water vapor. Under a certain pressure condition, the water vapor contained in the air is related to the temperature. The higher the temperature, the more water vapor it can hold. But relative to each temperature, there is a saturation value, beyond this saturation value, water vapor will condense and become liquid water. The temperature corresponding to this saturation value, that is, the temperature at which water vapor in the air begins to condense, is called the dew point temperature, or "dew point". The relationship between the dew point temperature and the moisture content of the ambient atmosphere is a one-to-one correspondence, that is, each dew point temperature corresponds to a moisture content value of the ambient atmosphere, and vice versa. The dew point can be simply understood as the temperature at which the water vapor content in the gas reaches saturation, or the ambient temperature when the humidity is 100%. When the water vapor content in the air remains unchanged, the drop in temperature can make the unsaturated water vapor in the air become saturated vapor, and the excess water will be precipitated, that is, condensation will appear.
结露现象在日常生活中普遍存在，特别是在冬季和梅雨季节结露现象更为明显。在房屋住宅中，结露、结霉不仅会腐蚀围护的结构材料，影响房屋的使用观感，而且会对居民的身体健康构成威胁。随着房地产市场的日益发展，不仅房屋住宅的数量规模引人瞩目，而且住宅房屋的质量越来越受到重视。在现有已建成的住宅房屋中，时常发现有室内墙壁“渗水”发霉的现象，这种现象不仅与天气有关，而且与房屋的朝向、墙体的结构以及建筑材料有关。如何在房屋建设的设计、施工、防护等环节中采取措施，以避免上述房屋墙体结露的产生，达到提高房屋质量的目的，是当前住宅建筑工程中的重大技术课题。找出问题结症的第一步就是收集房屋结构与结露有关的数据，墙体环境的露点和结露的检测就是其中之一。目前对房屋室内结露的检测是使用传统的露点测量仪到现场进行测量。这种方式存在有下列缺陷：一是，每一次测量都要到现场布置一次测量器具，测量完毕后再拆除测量器具，工作量繁重而重复；二是，只能对当时环境的数据进行记录，无法满足持续实时检测的要求；三是，数据采集工作只能到现场进行，不能实现远距离传输数据，从而受到天气、人员等客观因素的限制。Condensation is ubiquitous in daily life, especially in winter and rainy season. In houses, condensation and mildew will not only corrode the structural materials of the enclosure, affect the use and perception of the house, but also pose a threat to the health of residents. With the increasing development of the real estate market, not only the quantity and scale of houses attract attention, but also the quality of houses is getting more and more attention. In the existing residential houses, it is often found that there is "water seepage" and mildew on the interior walls. This phenomenon is not only related to the weather, but also related to the orientation of the house, the structure of the wall and the building materials. How to take measures in the design, construction, protection and other links of house construction to avoid the above-mentioned house wall condensation and achieve the purpose of improving the quality of houses is a major technical issue in current residential construction projects. The first step to find out the root cause of the problem is to collect data related to the building structure and condensation, and the detection of dew point and condensation in the wall environment is one of them. At present, the detection of indoor condensation in houses is to use traditional dew point measuring instruments to measure on site. This method has the following disadvantages: first, each measurement must go to the site to arrange a measuring instrument, and then dismantle the measuring instrument after the measurement is completed, the workload is heavy and repetitive; second, only the data of the environment at that time can be recorded. It cannot meet the requirements of continuous real-time detection; thirdly, data collection can only be carried out on site, and long-distance data transmission cannot be realized, which is limited by objective factors such as weather and personnel.
