Appendix EDMMT712101 17. Appendix 17.1 Ventilation Method The ventilation method is mechanical ventilation using mechanical means and natural ventilation under natural conditions. 17.1.1 Natural ventilation Ventilation uses the outdoor wind pressure and buoyancy created by Exhaust air → <Natural ventilation> temperature differences between indoor and outdoor air.
Page 175 EDMMT712101 Appendix 17.1.3 Mechanical Ventilation Methods • General Ventilation The method of exhausting polluted air by changing the air of a room using an installed ventilator is called general ventilation. This type of air is suited for cases where the pollutant source such as smoke, steam, or odor has dispersed inside the room. Exhaust Polluted air Supply...
Page 176: Airflow Rate, Dynamic Pressure, Static Pressure
Appendix EDMMT712101 17.2 Airflow Rate, Dynamic Pressure, Static Pressure Airflow rate and static pressure are used to express ventilator performance. Both have a close relationship and are always necessary when considering ventilation. Understanding these two concepts is the first step for ventilation design. 17.2.1 Airflow Rate (Quantity) Airflow rate expresses the air volume that the ventilator exhausts (or supplies) in a unit of time, and generally the unit is m /h or m...
Page 177: Fan Type And Features
EDMMT712101 Appendix 17.3 Fan Type and Features 17.3.1 Axial and Centrifugal Fans Ventilators employ both axial and centrifugal fans, and the fans are used separately according to conditions and application. Axial fans are propeller type fans that can obtain a large airflow rate but they have weak pressure and are used for static pressure of 0-30 Pa.
Page 178: Operation Sound
Appendix EDMMT712101 17.4 Operation Sound A decision cannot be made simply on necessary airflow rate and static pressure. Acceptable noise is another factor that varies according to the type of room being ventilated. Be sure to select by considering such factors as the type of room being ventilated and the sensitivity of individuals in the room.
Page 179: Pressure Loss Calculation By Duct Ventilation
EDMMT712101 Appendix 17.5 Pressure Loss Calculation by Duct Ventilation For duct ventilators and range hoods (pressure type), exhaust ventilation is performed by all ducts. Calculation of ventilation airflow rate at that time requires calculating duct length, number of bends, components installed outdoors, etc., in order to find the proper ventilation airflow rate.
Page 180 Appendix EDMMT712101 17.5.2 Calculation of pressure loss for straight pipe duct  In the Case of Circular Ducts (1) Duct Resistance is Found by the Following Formula. The following formula is generally used to find Pressure Loss rP at time air flows in the straight pipe duct. γ...
Page 181 EDMMT712101 Appendix <View of graph> (Conditions) The ventilator used is a duct type ventilator • Necessary airflow rate: 300 m • Duct diameter: 15 cm • Duct length: 5 m Friction loss coefficient (Pa/m) 1 Find the intersection (A) for duct diameter d (15 cm) and airflow rate Q (300 m /h) that flows through the duct.
Page 182 Appendix EDMMT712101 17.5.3 Local Pressure Loss for Duct 1) Local Pressure Loss In the bend part of the duct and diagonal change, there is loss in quality that is different from the straight pipe such as the vortex. The following formula expresses for pressure loss other than these straight pipes. P = ζ...
