  • Page 5: Necessity Of Ventilation

    CHAPTER 1 Ventilation for Healthy Living Fresh outdoor air must be introduced constantly at a set ratio in an air conditioning system. This fresh air is introduced to be mixed with the return air from the room, to adjust the temperature and humidity, supply oxygen, reduce body and other odors, remove tobacco smoke and to increase the cleanness of the air.
  • Page 6 CHAPTER 1 Ventilation for Healthy Living In the case of Japan, an Instruction Guideline based on these regulations has been issued, and unified guidance is carried out. Part of the Instruction Guideline regarding ventilation is shown below. The fresh outdoor air intake must be 10 m or higher from ground level, and be distanced appropriately from the exhaust air outlet.

    CHAPTER 1 Ventilation for Healthy Living 3. Ventilation Method 3.1 Ventilation class and selection points An appropriate ventilation method must be selected according to the purpose. Ventilation is composed of “Supply air” and “Exhaust air” functions. These functions are classified according to natural flow or mechanical ventilation using a fan (forced ventilation).
  • Page 9 CHAPTER 1 Ventilation for Healthy Living 3.2 Comparison of ventilation methods There are two main types of ventilation methods. Centralized ventilation method This is mainly used in large buildings, with the fresh outdoor air intake being installed in one machine room. For this method, primary treatment of the fresh outdoor air, such as heat recovery to the intake air and dust removal is performed being distribution to the building by ducts.

    CHAPTER 1 Ventilation for Healthy Living 4. Ventilation Performance The ventilation performance is largely affected by the installation conditions. Ample performance may not be achieved unless the model and usage methods are selected according to the conditions. Generally, the ventilation performance is expressed by “Air volume” and “wind pressure (static pressure)”, and these are necessary when considering ventilation.

    CHAPTER 4 Characteristics 4. Sound Sound is emitted when any object is excited causing it to vibrate. The object that vibrates is called the sound source, and the energy that is generated at the source is transmitted through the air to the human ear. Humans can hear the sound only when the ear drum vibrates.
