Two, kitchen appliances exhaust fan classification
Exhaust fan is the use of air convection can be indoors has been in a negative pressure state, the formation of a suction, a steady stream of outdoor air, and discharge indoor hot air, so as to achieve ventilation, cooling effect.
1, according to the air inlet and exhaust port
(1) exhaust fan according to the air inlet and exhaust port is divided into:
partition wall type: partition wall hole on both sides of the free space, from the side of the partition wall to the other side of the air;
conduit exhaust type: one side of the free space from the air inlet and the other side of the exhaust through the conduit;
conduit intake: one side of the intake through the conduit, and the other side to the free space exhaust;
conduit intake: one side through the conduit intake, and the other side to the free space exhaust. The other side exhausts into the free space;
Full duct type: ducts are placed on both sides of the exhaust fan, and the air is intake and exhaust through the ducts.
(2) according to the form of airflow is divided into:
Centrifugal: air enters in the direction parallel to the axis of rotation, and discharges perpendicular to the direction of the axis;
Axial: air enters in the direction parallel to the axis of rotation, and discharges parallel to the direction of the axis;
Cross-flow: air enters and discharges perpendicular to the direction of the axis.
2, according to the way of air
Exhaust fan of the way of exhaust, inhalation, and with three kinds of air.
Exhaust: from the natural air intake into the air, through the exhaust fan discharged dirty air;
Inhalation: through the ventilation fan to inhale fresh air, from the natural exhaust vent discharged dirty air;
And with the type: inhalation and exhaust are by the ventilation fan to complete.
Three, kitchen appliances exhaust fan specifications
1, the current circulation of the exhaust fan on the market there are three main specifications, respectively:
(1) 1380 * 1380 * 400mm1.5 kilowatts
(2) 1220 * 1220 * 400mm1.0 kilowatts
(3) 1060 * 1060 * 400mm0.0 kilowatts
(3) 1060 * 1060 * 400mm0.0 kilowatts. 1060*400mm0.75kw
2, the way of rotation can be divided into belt rotation and motor direct rotation of two kinds:
(1)Belt rotation of the exhaust fan rotation speed is generally 400 ~ 450 rpm, with low noise characteristics;
(2)Motor direct rotation of the exhaust fan rotating speed is higher, 440 ~ 720 rpm. The speed of the exhaust fan is 440~720 rpm.
3, from the blade structure:
There are mainly five blades, six blades, seven blades three kinds of structure.
