The unit distributes air to various locations within a structure by using one of two techniques.
Consequently, there are four mechanical whole-house ventilation systems to choose from: exhaust, supply, balanced and energy recovery. He loves penning pieces on subjects related to business, health, law and technology. Two types of balance ventilation systems exist: heat recovery ventilation (HRV) and energy recovery ventilation (ERV). Buildings are provided with smoke ventilation systems in order to remove smoke and heat from them. This is a bit of an issue, considering these types of days are when cross ventilation systems are required most.
Soma Tech Intl offers many different types of ventilator options in addition to the multitude of medical equipment units that can stock a healthcare facility.

He worked several years as a senior manager in the housing industry before pursuing his passion to become a writer.
Here's what you need to know! Its purpose is to improve, A steady supply of outdoor air for improved indoor air quality and resident comfort, Regulation over the amount and source of outdoor air, Thinning of indoor contaminants, such as odors and allergens, Helps control relative humidity and decrease moisture accumulation during the heating or temperate seasons, Contaminants may be drawn into the house from an attic, garage, crawlspace or wall cavity, Possible to draw moist outdoor air into the wall cavity that could condense during the cooling season and cause moisture problems, particularly in hot and humid climates, Can cause or contribute to back-drafting of combustion appliances, Lowest installed cost and low operating cost, Reduces contaminants entering through the building enclosure, Outdoor air is drawn from a single, known location for best air quality, Potential to drive moist indoor air into the wall cavity that could condense and cause moisture problems during the heating season in colder climates, Low installed cost, however for a CFI system, the electronically commutated motor may increase the initial cost and operating cost may be higher, An HRV transfers a portion of the heat between the exhaust air and the fresh air; an ERV transfers heat and moisture, An HRV or ERV provides the benefits, but limits the drawbacks, of supply-only and exhaust-only methods, Commonly, an HRV is recommended for dry, cold climates and an ERV is recommended for moist, warm climates, Highest installed cost for HRV or ERV due to equipment and additional ducting. Supply-only ventilation consists of a fan drawing outdoor air into the house. A ramp function can allow the user to lower the pressure if the patient is trying to fall asleep. Data integration helps to support communication with all major patient monitoring and already integrated hospital information systems with an electronic transfer of data. Overall, this piece of equipment is reliable, durable, and easy to service.

However, because cross ventilation involves ventilating a structure at two opposing sides, cross ventilation is, generally, a better solution for natural ventilation. Therefore, making the building’s occupants more comfortable. They’re a flexible system, designed to allow for ease of operation. Indoor air escapes through the building enclosure and exhaust fan ducts. This helps to keep escape routes clear, in the event of a fire. Not in your facilities budget? This unit uses waveform graphics, oxygen cylinder usage calculator and an internal battery. Stack ventilation works by drawing cooler outside air into the building at a lower level, which becomes warmer as it’s exposed to heat sources within the building, causing it to rise before it is vented out at a higher level. Vacuum systems which extract air from the building via an exhaust fan, so internal air pressure is lower than the outside air. on Mar 3, 2016 1:10:56 PM.
Soma stocks a wide variety of spare parts for all equipment that we sell.
For example, we offer rain & remote controllers, wireless timers and thermostats. Balanced ventilation systems are a combination of exhaust and supply methods roughly providing equal indoor exhaust and outdoor supply air flows (e.g.
By connecting the vent to the primary return air duct, it conditions the outside air before distributing the air inside the building. All of our products have been tested to European EN standards. Air is moved due to the pressure drop between the fan inlet and outlet vent. Enter your email address to subscribe to this blog and receive notifications of new posts by email.

Natural ventilation occurs by circulating air through vents, windows, doors and open spaces. Although natural ventilation is usually preferable to mechanical, natural ventilation is not always possible.
Cross ventilation is generally suited to buildings that are narrow but not too deep. Not only will this reduce humidity levels and keep internal temperatures more comfortable, but it will replenish the oxygen and remove any harmful contaminants from the air too. Hospitals and Medical facilities love this ventilation device because of the overall low cost of ownership. Houses have become considerably tighter during the past 15-20 years as a result of changing codes, energy efficiency programs and an overall desire to reduce energy use. This unit can be customized with custom presents and custom backup ventilation. Exhaust-Only Ventilation. Some people choose to rent before buying because they want to try out a new piece of equipment. Continue reading to learn more about how the different types of ventilation systems are refurbished by us.
