7 - 2 - 7 Reducing Operating Sound
1. Operating sound heard from the air discharge outlet can be
reduced just by applying sound-insulating material to the SA
(indoor air supply) duct.
2. Operating sound can be reduced more effectively by applying
sound-insulating material to a portion of the SA duct near the unit
body than that near the air su
ction / discharge grille.
7 - 2 - 7 - 1 Taking Measures to Reduce Operating Sound Heard from Attic-installed Equipment and Air Ducts.
1. When installing large air volume models (650 m
3
/ h or more),
avoid the following wherever possible if it is expected to be
necessary to apply sound-insulating material to them. (Fig.1)
(1)Making the duct diameter extremely small (Example: φ 250 →
φ 150, φ 200 → φ 100)
(2)Making the duct extremely bent using bellows (in particular,
connecting bellows to the air discharge outlet of the unit body)
(3)Making opening holes on the ceiling
(4)Hanging the unit on a m
aterial which does not have enough
hanging strength
2. Take the following sound reduction measures. (Fig.2)
(1)Use a sound-insulating (low-permeability-to-sound) ceiling.
Note :
Some sound-insulating ceilings are not very effective in reducing
low-frequency element of the operating sound.
(2)Place a sound-reducing material under the source of the
operating sound.
Note :
1 When using a sound-insulating sheet, it is necessary to have the entire body of the unit covered with it. Note, however, that some models
do not allow the use of a sound-insulating sheet because it may badly affect the ventilation of their radiation heat.
The air suction and discharge grille may give out operating sound higher by 8 to 11 phons than of the HRV units body.
When ins
talling this unit in a quiet place, take measures to reduce operating sound.

- Purpose of ventilation 255
- Carbon monoxide co carbon monoxide is colorless odorless and very toxic gas imperfect combustion of briquette charcoal or oil produces co gases tobacco smoke and automobile exhaust gases also contain co gases co gases inhaled into the lung join together with hemoglobin in the blood which result in preventing the bonding between oxygen and hemoglobin leading to inability to convey oxygen to the tissues of the human body the bonding force between co and hemoglobin is 200 300 times larger than that between oxygen and hemoglobin a typical symptom is headache the motor of their limbs is anaesthetized before losing consciousness so that they cannot escape away from the place which may in the worst case lead to fatal accident inhaling co gases repeatedly may lead to chronic poisoning with short memory or in the worst case he she is crippled for life the normal atmosphere contains about 21 of oxygen combusting the air will reduce the oxygen concentration when it reduces to 19 co concentration 256

- Hydrogen and various hydrocarbons including methane and traces of hydrogen cyanide formaldehyde acrolein ammonia and nitrogen oxides nox so that various human health problems including lung cancer chronic co toxication and bronchitis can occur new ceilings walls furniture and decorations in white will turn into yellow in one or two years this is due to the nicotine and tar contained in tobacco smoke and or dust in the air to allow smoking proper ventilation is inevitable a ventilation system consisting of an air cleaner and ventilator that operates automatically detecting the level of pollution is recommendable this system can be associated with an air conditioning system so that power consumption for these systems can be reduced and so that they can enjoy comfortable smoking without feeling hot or cold 256
- Table 3 sensation for tobacco smoke 256
- Table 4 air pollutants per cigarette when smoking 256
- Table 5 256
- Tobacco only one cigarette can soon pollute the air in the enclosed room and both the smoker and other non smokers staying here are affected especially the secondhand smoke from the tip of cigarette contains 2 3 times larger amount of harmful substances nicotine and tar than the main smoke exhaled by the smoker so that the non smokers around the smoker can be affected by tobacco smoke so tobacco smoke is one of the serious causes of interior air pollution tobacco smoke consists mainly of mists such as tar and nicotine gases such as carbon monoxide co carbon dioxide c 256
- Carbon dioxide c 257
- Carbon dioxide gas is a normal component of the air normal concentration of about 0 4 physiologically c 257
- Fig 2 relationship in concentration between oxygen and co 257
- Gas is requisite for human life the gas stimulates the respiratory center for unconscious automatic breathing c 257
- Gas will adversely affect the human body though the effect closely depends on the oxygen concentration 257
- Gases are used as an indicator of the atmospheric condition in the room not treated as a toxic gas higher concentration of c 257
- Gases dissolve into blood to maintain the oxygen concentration at the proper level for the purpose of sustaining normal functions of human body hygienically c 257

- Are harmful and account for large portions of nox compounds n 258
- Concentration is normal for human body lower 258
- Concentration of 8 or lower will have a fatal effect higher 258
- Concentration will cause difficulty in breathing with other various symptoms 258
- Concentration will cause our pulse rate to increase which leads to larger burdens on the heart abnormally higher 258
- Concentrations invite another danger higher ignition possibilities therefore artificial oxygen supplies should be avoided the most effective way for avoiding oxygen starvation is to supply natural air that contains oxygen concentrations appropriate for human life 258
- Continual generation of high temperatures in an enclosed space thus requires ventilation n 258
- Gases electric ovens also produce n 258
- Gases though their amount is smaller and this is not well known that is high temperatures regardless of combustion facilitate bonding between n and o atoms in the air which results in the increase in the amount of n 258

- Hrv vkm ga m v1 258
- Nitrogen dioxide can easily reach the deepest part of the lung and adversely affect it and other organs in terms of long term adverse effect nox is stronger than sulfurous acid gases dusts can enhance the adverse effect of nox gases no nitrogen monoxide is also harmful though its chronic effect is yet to be clarified 258
- Nitrogen oxides nitrogen oxides nox include no n 258
- Of these no and n 258
- On human body 258
- Oxygen starvation about 21 of 258
- Produced by other than combustion oil heaters and gas ovens for oxygen based combustion produce a large amount of n 258
- Sulfurous acid gas volcano exhaust automobile exhaust or oil fuel combusted gas and mist contain sulfurous acid gases in the form of being adhered or absorbed onto suspended dust particles these gases are a possible cause of chronic bronchitis or other respiratory diseases 258
