Answer:
about ceiling fan
Explanation:
Ceiling fans are one of the main power consuming sources. Total power consumption is multiple of fan rotation frequency. As India is facing the power crisis it is important to reduce the power consumption in every power consuming device. Hence Power reduction in ceiling fan is perhaps one of the most important parameter. Every power reduction process starts with identification of power consumption sources. Ceiling fans are extensively used to create an indoor breeze, improve the space air distribution and hence enhance the feeling of comfort. The fan speed, diameter, number of blades, blade angle and vibrations all play an important role in deciding the power consumption. Few previous studies have investigated fan induced flow and its characteristics under different geometric and operating conditions .In this study ,response surface methodology is used to predict power consumption characteristics. The experiments were conducted based on the three different fans having three different blades, three room size, three different ceiling fan rod lengths three regulator knob positions and mathematical model was developed.
