As we all know, the heat dissipation of equipment in the data center is particularly large. It requires a safe and reliable operating environment for equipment in the data center, including temperature, humidity, cleanliness, etc. In order to solve the challenges of high density and thermal load in data centers, Titanflor has developed a series of high-efficiency and energy-saving solutions. Sensor fan assist floor can automatically determine the on-site temperature, and make real-time reflections based on sensor signals, automatically adjust the temperature. The temperature-controlled fan is an upgrade of a function of the ordinary fan, and the scope of use on the market is becoming wider and wider. However, many people don’t know much about how the sensor fan assist floor works. So, what is the working principle of the sensor fan assist floor?
How does the sensor fan assist floor work?
Sensor fan assist floor is an intelligent fan system raised floor, with automatic temperature control fan to provide a blast of cooling, through an individual directional airflow perforated panel. The temperature controlled fan units are available quad fan models. The fan has multiple control options to automatically turn on when conditions require additional cooling.
1. The operating principle of the temperature-controlled fan
It mainly relies on the temperature rise around the fan. It will speed up the speed of the fan itself and increase the air volume between the air. The temperature-controlled fan mainly senses the temperature change of the surrounding air through the thermistor on the fan. The thermistor can sense the wire when the fan is running. Running at a slower speed, the fan will make less noise and consume less energy. In most design requirements, the air temperature is usually lower than the maximum design temperature after we cranked up the fan for several hours. Under normal circumstances, the cooling fan running at low speed is sufficient to do its job.
2. There is a bimetallic sheet inside the temperature control switch. It has different thermal expansion coefficients. So when it reaches a certain range of critical temperature, the contacts can be deformed. And there will combine the contactsto achieve the purpose of electrification. Start position, disconnect the line. This is mechanical. We will mark the values on the surface of the temperature control switch.
Thermostatic fans use a thermistor to sense temperature, and sensors mounted on the fan hub detect the temperature passing through the fan. In this configuration the fan must be properly installed, and the thermistor can sense through a special connecting wire when the fan is installed.
Fan operation changes with heat, and at slower speeds, the fan will make less noise and consume less energy. In most design requirements, the air temperature is usually lower than the maximum design temperature after we cranked up the fan for several hours. Under normal circumstances, the cooling fan running at low speed is sufficient to do its job.
When selecting and installing, consider:
First of all, the selected fan must be able to provide enough exhaust air volume (speed). It will cool the hot air inside the device under high temperature conditions; when the temperature is relatively low and the hot air flow is relatively small, it does the opposite.
Secondly, when choosing the installation location of the sensor, you should pay attention to placing the sensor in an appropriate position. So that we can clamp the sensor on the surface that needs cooled.
