Sub-assembled air conditioner filter

Sub-assembled air conditioner filter, muffler, humidifiers, dehumidifiers, etc.
Section I of Chapter VIII of the ventilation and air conditioning engineering Overview Ventilation Ventilation is the outdoor fresh air after appropriate processing (such as purification, heating) and sent to the room, the the indoor exhaust gas (pasteurized, pesticides) row to the outdoor , to keep the indoor air fresh and clean. Second, the air conditioning works Air conditioning is the use of technical means to a particular space within the air environmental control in a certain state, to meet human comfort or process requirements, ventilation. Under the control of the content, including air temperature, humidity, flow rate, pressure, cleanliness, component, noise, etc.. , Ventilation and air conditioning engineering commonly Legend section II, ventilation and air conditioning equipment and components installed, ventilation and air conditioning equipment and componentscartridge filter housing
(A) ventilator fan centrifugal fan and axial fan. High pressure centrifugal fan, low noise, suitable for longer air supply piping system, axial fan, air volume in the same power, wind down, for short pipe, resistance and air flow required large spaces. 1, the representation of the centrifugal fan, fan models and performance parameters should be marked on the name plate of the fan. Example: Type 4-74-11NO4.5A fan - fan when the maximum efficiency point pressure coefficient multiplied by 10 after taking an integer value, the pressure coefficient of the wind turbine is 0.4, non-powered fan. 74 - more than the number of revolutions. 11 - The first number is the suction form, according to the clues provided by the owners, single inlet 1 (double inlet 0, two series of 2), the second number represents the design sequence number, the first times design. NO4.5 - fan machine number, the percentage of the fan outer ring (mm), the wind turbines impeller diameter to 450mm. A - Transmission code, the wind turbines have no bearing direct-drive. 2, the representation of the axial fan, axial fan casing, impeller, diffuser, motor, its representation letters and numerals. Example: axial fan × 25 ° 1860 × 36 1.5 / 2 axial fan A6 × ° × A - indicates that the fan and the motor directly connected. 6 - 6 - the number of leaves. 25 ° - leaves the mounting angle. 1860 - fan flow 1860m3 / h. 36 - Fan residual pressure of 36Pa. 1.5/2-- fan power to 1.5kW, 2-pole.nylon filter bag
(B) air conditioner ventilation and air conditioning engineering quota within the meaning of air conditioners include: new fans, air handler (air conditioners cabinet), sub-assembled air conditioner, the overall air conditioning units. 1, new fans, air handlers new fans, new fans air handler: two parts by the fan and evaporator, and integrate them in the same cabinets. 2, sub-sub-assembled air conditioner assembly air conditioner: In addition to the fan and the evaporator, the sub-roof axial fan, assembled air conditioner filter, muffler, humidifiers, dehumidifiers, etc., each of which has a separate box, through the flange on request free combination. 3, the overall air conditioning units: the compressor, condenser, evaporator, the overall air conditioning units: the overall air-conditioning unit ventilators, humidifiers, heaters, air filter, automatic adjustment and electrical control devices assembled in a box within.
