PURPOSE:To make it possible to shorten a space heating operation time, to carry out an efficient space heating operation and to improve the comfortableness of a living space by setting a desired air flow direction position and automatically directing a hot air flow or a cold air flow toward ...
摘要: PROBLEM TO BE SOLVED: To improve an air blowing efficiency for a foot area or the like by a method wherein a vertical flap is arranged at an upper surface of an air blowing grill and cooperatively operated with a vertical main flap so as to be rotated in a vertical direction....
How is the working of an electric bell affected, if the alternating current is used instead of direct current? Find the currents I1, I2, and I3. What is the SI unit of the electric flux? Why AC (Alternating Current) is sinusoidal or alternating? What are the directions of the elect...
Particles made of titanium dioxide TiO2 having a particle size in the range of 0.5 − 2 μm were used as particle tracers for visualizing the air flow. The particle-tracers were brought into the flow through the intake (1) by using the seeding generator (7). The operation principle of ...
What is a subsiding air current? At what direction will a compass spin when at the North Pole? What is potential flow theory? What is the current in a 660V circuit if the resistance is 2.5 k ? What is the unit of electrical current?
CONSTITUTION: A suction port(1) is formed at the front of a main body. Discharge ports(2) are formed at both sides of the main body. A discharge control unit drives air sucked through the suction port and exchanging heat in one direction to discharge most of heat-exchanged air through ...
