When a person gets an upper respiratory infection like the flu or a cold, or simply congestion in their chest or their throat, they may turn to a doctor for prescribed medications such as an antibiotic to kill the infection. But if that antibiotics are not effective or the patient becomes severely ill, then they are often advised to take oral corticosteroids to reduce the inflammation or steroids to treat any inflammation of the lungs. If a patient is also suffering from COPD (chronic obstructive pulmonary disease), or lung cancer, then surgery may be necessary to remove part or all of the diseased tissue. But even after surgery, the lungs of the patient may still not be healthy and may require ventilation systems for offices, especially large offices such as clinics or hospitals. Ventilation systems for commercial buildings are necessary to help patients’ lungs recover from such diseases and enable them to work again.
The purpose of ventilation systems for commercial buildings is to improve the indoor environment’s ability to retain moisture, air, and air-conditioning. In the absence of ventilation systems, these conditions could easily lead to the mould and mildew growth that result in such infections and diseases. While it is important to have adequate ventilation systems for offices because the air-change rate in such structures is much higher than for homes, it is also equally important for public ventilation systems to be efficient and effective. And here are some of the things you should know about the ventilation systems for commercial buildings.
Types of Ventilation Systems
There are two types of ventilation systems – mechanical ventilation systems and air-change ventilation systems. Mechanical ventilation systems involve openings at the ceiling, floor, walls, or floors where ventilation is needed; air-change ventilation systems have vents that open into a mechanically vented room or area. Because these ventilation systems depend on the presence of a physical ventilation hole, they are more susceptible to the occurrence of condensation. They can also be more effective if the insulation in the building is vented into the ventilation hole so that warm air from inside can escape, and cold air from outside can enter.
Both of these ventilation systems rely on one basic principle: the ventilation rate. The ventilation rate is the amount of air (in cubic feet per second) that is exchanged per minute through the ventilation holes. In natural ventilation systems, the ventilation rate is determined by the humidity, temperature, wind, and other natural forces that force air upward. With the existence of artificially created ventilation systems, however, the ventilation rate changes based on the type of ventilation holes.
Natural ventilation systems have an advantage over artificially created ventilation systems. First, they don’t need to be closely watched and maintained like mechanical ventilation systems. A good example of an artificially created ventilation system is the ceiling fan that works in conjunction with the home heating system. If these fans are not properly designed, they will produce a stream of air that goes directly from the top of the ceiling to the room where it is needed most – causing the warm air in the attic to go through the ventilation shaft instead of being distributed throughout the entire room as needed. If this were to happen, there would be much more air in the attic and the home would feel much warmer. Such a situation could lead to many problems, including increased heating bills and aches and pains.
Another important difference between ventilation systems and natural ventilation systems is that the former relies on the heat-recovery principle. The heat-recovery principle is used in heating systems because it helps warm up a cold object by trapping heat from the air surrounding it. In artificial ventilation systems, the heat-recovery principle is not that effective. For the system to work properly, it needs a constant moisture input (humidity means moisture vapour) from the air.
Alternatives
An alternative to heat exchangers in ventilation systems is energy recovery ventilation systems. Energy recovery ventilation systems rely on the fact that many homes have the same ventilation rates as specified by the US Environmental Protection Agency. A heat exchanger works by exchanging heated air with cold air to produce a new, higher temperature. As long as the exchanger can maintain that temperature, it will keep heating bills down. Energy recovery ventilation systems work by using the same principles as heat exchangers – it just uses a different way to change the heat entering the home into cool air, which is then circulated through the home. Energy recovery ventilation systems also use less energy than a conventional ventilation system would.
Ventilation fans can also be an effective way to cool your home. These ventilation systems work by pushing hot air out of your home and replacing it with cooler air. When your home is not burning hot, you don’t need to worry about your family’s health. In addition to cooling your home, ventilation systems also can prevent you from experiencing cold flashes. This can save you on energy costs and reduce your exposure to harmful allergens.
