Why people will feel cool? As a result of the human body has a lot of sweat, when after the fan works, indoor air will move, so it can promote the rapid evaporation of sweat, separation 'evaporative demand to absorb a lot of heat, so people can feel the cool. Parallel fan: parallel double fan air pressure is constant, but the wind will rise. Air volume increase so the heat dissipation effect increased, and if present in the design cooling power is too small can think to increase the fans to deal with. Series fan: series fan is the result of the wind pressure increases, but the air flow is constant. This way is not to tackle the problem of heat dissipation is common used in some wind resistance is too large when using, ensure air volume. In order to reduce the low noise in the process of use must pay attention to the following: system impedance: air resistance will provoke up air activities produce noise. Turbulent flow: due to the port to form the design of the bad air turbulent flow can have high frequency noise is present, if the port is not improve it is difficult to have a qualitative progress. Fan speed and size, the faster the speed of the fan cooling effect, the better, the bigger the size of the fan air volume, the greater the heat dissipation effect is better. The fan speed, the higher the noise, the greater the size, the greater the noise. Temperature rise: low after the temperature rise of temperature, cooling effect is reduced. Vibration: will form a rise in the noise of the fan, reduced life spans and lower speed. Voltage shake: shake can form fan speed change, make the job instability and generates additional noise.
