Humidistats are used in a number of devices including dehumidifiers, humidifiers, and microwave ovens.In humidifiers and dehumidifiers, the humidistat is used where constant relative humidity conditions need to be maintained such as a refrigerator, greenhouse, or climate-controlled warehouse. [2]
A typical "portable" dehumidifier can be moved about on built-in casters. A dehumidifier is an air conditioning device which reduces and maintains the level of humidity in the air. [1] This is done usually for health or thermal comfort reasons or to eliminate musty odor and to prevent the growth of mildew by extracting water from the air. It ...
A household electric fan A large cylindrical fan. A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner. Usually, it is contained within some form of housing ...
Philip H. Diehl (January 29, 1847 – April 7, 1913) was a German-American mechanical engineer and inventor who held several U.S. patents, including electric incandescent lamps, electric motors for sewing machines and other uses, and ceiling fans.
An internal fan-cooled electric motor (colloquially, fan-cooled motor) is a self cooling electric motor.Fan cooled motors feature an axial fan attached to the rotor of the motor (usually on the opposite end as the output shaft) that spins with the motor, providing increased airflow to the motor's internal and external parts which aids in cooling.
Figure 1: Components of a centrifugal fan An external motor belt driven inline centrifugal fan discharging inline to the exterior of a building through a duct. Unlike non-inline/non-concentric impeller casing design with a cutoff blade above, the concentrically symetric cylinder casing and impeller geometry of inline type redirects the outflow around so that it is parallel to the inflow of gases.
An external fan blows outside air over the frame of the motor to cool it. This motor is arguably the most commonly used motor in ordinary industrial environments. TEFC enclosed motors usually cost more than open motors, but offer increased protection against weather, dirt, and moisture. TEFC motors are constructed with a small fan on the rear ...
