室内气流速度评价是工程中一项重要参数。热球式风速仪是测量气流速度的仪表,在工程中应用十分广泛。根据国家《计量法》统一计量单位制和量值准确可靠的原则,此种仪表应在计量检定合格后才能使用。由于国内目前尚无检定热球式风速仪用的计量检定规程,给实施计量检定带来困难。建设部为此下达了编制行标《热球式风速仪计量检定规程》的任务,由中国建筑科学研究院空调研究所负责主编。
The evaluation of indoor airflow speed is an important parameter in the project. The hot ball anemometer is a meter for measuring the air speed and is widely used in engineering. According to the “Measurement Law” of the State, the principle of a unified measurement unit system and accurate and reliable measurement values shall be used. Such instruments shall be used only after passing the metrological verification. As there is no metrological verification procedure for the verification of hot-ball anemometer at present, it is difficult to implement metrological verification. The Ministry of Construction has issued the task of compiling the “Verification Test Rule for Hot-ball Anemometer”, which is chiefly edited by the Institute of Air Conditioning, China Academy of Building Research.
