Thermal comfort is a subjective evaluation of a person's satisfaction with the surrounding thermal environment (ISO 7730), mainly divided into three aspects: physical, physiological, and psychological. The evaluation indicators mainly include Bayesian scale, ASHRAE scale, and ISO standard. Jiantong Technology JT2180 indoor thermal comfort measurement instrument adopts ISO standard evaluation method (corresponding to China: GB/T18049) ISO has developed the ISO 7730 standard based on the research results of Professor PO Fanger from Denmark, in which the PMV-PPD index is used to describe and evaluate the thermal environment. This indicator comprehensively considers six factors, including human activity level, clothing thermal resistance, air temperature, air humidity, average radiation temperature, and air flow velocity, in order to meet the thermal balance equation of…

Application of Wind Speed Sensor in Coal Mine Ventilation Tunnel 1. Wind speed monitoring: Wind speed sensors can be used to monitor the wind speed in coal mine ventilation tunnels. By monitoring the wind speed in the ventilation tunnel, the operation status of the ventilation system can be timely understood, ensuring its normal operation and avoiding safety risks caused by abnormal wind speed. 2. Air quality monitoring: In coal mine ventilation tunnels, wind speed sensors can also be used to monitor the flow of air, including its flow rate and direction. By monitoring the flow of air, it is possible to determine whether the air quality meets the standards, and promptly identify and solve air quality problems in ventilation tunnels.…

Application of wind speed sensors in vehicle air conditioning comfort: Thermal wind speed sensors can play an important role in measuring the comfort of new energy vehicles. New energy vehicles usually use electric drive systems, and compared to traditional cars, their internal mechanical components operate more smoothly, with less vibration and noise, Providing passengers with a quieter and more comfortable riding experience. However, the air conditioning system of new energy vehicles also needs to consider issues of energy conservation and battery life while ensuring a suitable temperature inside the vehicle. And thermal wind speed sensors can help The vehicle management system monitors and regulates the air flow rate inside the vehicle in real-time, thereby improving the comfort of new energy…
