The differential pressure air tightness tester is one of the key tools to evaluate the air tightness performance of buildings. It evaluates the airtightness performance of a building by measuring the difference in air pressure between its interior and outside. However, there are some disadvantages that correspond to its advantages, and this article will provide an in-depth understanding of the advantages and disadvantages of differential pressure air tightness detectors.
Advantages:
High precision: Differential pressure air tightness testers usually have high accuracy and are able to accurately measure the air pressure difference between inside and outside the building, thus providing reliable air tightness performance data.
Wide range of applications: The differential pressure air tightness tester is suitable for various building types, including residential, commercial buildings, industrial plants, etc., with strong versatility and flexibility.
Fast and efficient: The test process of differential pressure air tightness tester is relatively simple and fast, and the test can usually be completed in a short time, improving construction efficiency.
Accurate positioning: The differential pressure air tightness detector can accurately locate the air leakage points and poor sealing places inside the building, and help the construction personnel to repair them in time.
Quantifiable results: The test results provided by the differential pressure air tightness tester are quantifiable and are usually presented in the form of air tightness index or air tightness class, which is convenient for evaluating the air tightness performance of buildings.
Disadvantages
Affected by the environment: The test results of the differential pressure air tightness tester are greatly affected by environmental factors, such as air temperature, wind speed, etc., and need to be tested under appropriate climatic conditions to ensure accuracy.
The operation technology is demanding: The technical requirements for operators are high, and certain professional knowledge and skills are required to ensure the accuracy and reliability of the test.
The cost of equipment is higher: The equipment cost of differential pressure air tightness tester is high, and there may be some economic pressure for some small construction companies or individual users.
The maintenance cost is large: The maintenance and calibration of the equipment requires a certain amount of money and time investment, including regular overhaul and maintenance, to ensure the normal operation and accuracy of the equipment.
It is not possible to measure local air leakage points: In some cases, differential pressure air tightness detectors may not be able to accurately measure local air leaks, especially if the building structure is complex or sheltered.
Conclusion
The differential pressure air tightness detector has the advantages of high precision, wide range of application, fast and efficient, but also has disadvantages such as environmental impact, high operation technical requirements, and high equipment cost. Therefore, when selecting and using differential pressure air tightness detectors, it is necessary to comprehensively consider its advantages and disadvantages, and take corresponding measures to ensure the accuracy and reliability of the test results.
