Thermal Anemometers: Measurement applications in heating and ventilation systems
With the improvement of living standards, heating and air conditioning systems are used in many places, and the installation technology of heating and air conditioning systems directly affects people's health. Changes in airflow at air conditioning vents, HVAC discharge vents, exhaust vents, etc. are directly related to human comfort. For changes in airflow, installers usually use anemometers to measure air flow velocity and temperature. Among them, the most widely used anemometer is the thermal anemometer.
Anemometers can be divided into constant-flow anemometers and constant-temperature anemometers. Constant-temperature anemometers have small thermal lag effects, wide frequency response, and fast response, while constant-flow anemometers do not have the above characteristics. The main uses of the anemometer are: measuring the speed and direction of the average flow, measuring the pulsating speed and spectrum of the incoming flow, measuring the Reynolds stress in turbulent flow and the velocity correlation and time correlation between two points, measuring wall shear stress, and measuring fluid Temperature etc. It is one of the anemometers with high response sensitivity.
The air supply temperature of the heating system directly affects the comfort of the human body; what is the air flow rate and wind speed of the air outlet to keep the indoor air fresh? These problems can be solved by measuring with a thermal anemometer. This anemometer is a professional anemometer with stable performance, safety and reliability. It can measure wind speed, air volume, air temperature, etc. It has high accuracy and small error. It has a portable design and is easy to carry with you to various working points for measurement.
Equipped with a USB interface, maximum value, minimum value, average value and data retention function, this thermal anemometer can input data into the computer, and multiple analysis value displays make it easier for users to conduct data analysis. In addition, the anemometer has a measuring range of 0.2-20m/s and a thermal wind speed retractable probe, which can easily handle measurements in small spaces. For the measurement of air volume in the pipeline, using this anemometer for measurement, you only need to input the cross-sectional area of the pipeline, and the air volume can be automatically calculated.
With a large backlit LCD display, this thermal anemometer can be used easily even in a dark environment and can clearly read the measurement values. Thermal anemometers can be widely used in monitoring indoor air quality and industrial health environment engineering, environmental testing in pipelines, and performance debugging of HVAC equipment.
