The Importance of Ventilation in HVAC

The Importance of Ventilation in HVAC

ventilationWhen researching a variety of topics on behalf of your St Louis Heating Sales and Installation near St Charles, we ran across several in pursuit of more knowledge on the ventilation portion of the HVAC system.  As a result, we have decided to further discuss it here.  “The purpose of mechanical heating, ventilation, and air conditioning (HVAC) systems is to provide air at comfortable temperature and humidity levels, clear of harmful pollutants such as mold, mildew, and other bacteria. Although heating and air conditioning systems are relatively standard operations, complex ventilation processes can often determine the quality of our indoor air.”

Once upon a time, ventilation was simply open windows, adding a fan would increase your ventilation’s effectiveness, but fell short in many heating and cooling scenarios, nonetheless.  In today’s day and age, modern buildings typically use a combination of mechanical ventilation processes, resulting in the supply and removal of air from inside a building or home. “Ventilation processes bring in the air from outside, condition and mix the outdoor air with a portion of the indoor air, distribute the mixed air throughout your home or building, and send a portion of the indoor air back outside.

It is our experience in the St Louis Heating Repair near St Charles that when one or more of these ventilation processes fails, indoor air quality can and will deteriorate. For this reason, your ventilation is one of the most important aspects to Heating and Cooling near St Charles MO.  “Proper design, operation, and maintenance of the ventilation system is critical to providing indoor air that is free of harmful pollutants.”  Whole HVAC systems in place in your St Charles home can also be large contributors to issues with indoor air quality, so should be properly maintained every year as well.  Your St Louis Heating Maintenance near St Charles offers these services to those in your area.

Ventilation Options Designed To Keep You Cool

Ventilation Options Designed To Keep You Cool

Air Ventilation DuctAs the weather begins to transition into fall, finding cooling options that utilize less energy can help your business save lots of money on utility bills.  That’s why it’s so important to consider how well your building’s ventilation systems are being used to your advantage.  Today, the team at American Services wants to give you some ideas on how to ventilate your commercial space this fall.

Your first option is natural ventilation.  Natural ventilation is accomplished by opening doors and windows that allow for fresh air to flow through your space.  To create the best air flow, be sure to open two windows across the same space.  If possible, keep windows open at night and then close them up in the morning to trap that cool nighttime air in your space.

The next option to consider is fans.  Ceiling fans work great to create a nice breeze across a room that can make it feel about 4 degrees cooler than it actually is.  Box fans are another great option and can be place in a window to draw air inside a space. Using fans in combination with your open windows will cool your space faster.

Finally, consider a whole house fan.  Whole house fans are installed in attic spaces and are designed to bring air up through your space.  The warm air is then exhausted from your roof.  When using a whole house fan it is best to run it at night with the windows open.  Then, simply turn off your fan and close the windows in the morning. Whole house fans use minimal energy and can reduce the time you need to run your air conditioning during the day.

If you feel like your commercial space could be better ventilated, feel free to contact the St. Louis city heating and cooling experts at American Services for a free estimate today!

The Best Cooling Systems are Energy Efficient

The Best Cooling Systems are Energy Efficient

industrial cooling in MOAmerican Services commercial cooling maintenance service near Fenton knows that in today’s market most cooling systems have an energy efficient design in order to save commercial businesses on energy costs.

Cooling systems must be designed with specific qualities in order to meet standards for the commercial industry.  In fact many systems today are almost completely maintenance free.

Other specs include; ensuring the protection or the system so it is free of dust and allergens, providing flexibility for adaptable cooling systems, and energy efficiency-which may be the most important aspect of cooling systems in today’s commercial market.

Many industry experts today say that utilizing water for cooling systems is the most efficient method of cooling today.  This principal is based on the fact that water has a high capacity for transporting energy efficiently compared to air systems.

One such cooling system is called evaporative cooling.  This type of cooling mechanism uses water to cool for spot cooling for approximately five hundred sq. ft. or less

Another energy efficient cooling option is a configuration that blows cool air from all 4 sides.  This type of cooling system does not generate enough cool air to cover as much area as the evaporative coolers.

In commercial buildings, superior climate control one that is energy efficient, will keep your costs down.

Other commercial cooling system options include; single or modular units, roof mounted HAVC systems which connect the  heating, air conditioning, and ventilation systems together in one  classification.

Energy Recovery Ventilation in Commercial HVAC

Energy Recovery Ventilation in Commercial HVAC

commercial HVAC systems in MOAmerican Services industrial HVAC repair and maintenance near Belleville knows that energy recovery ventilation is the energy recovery process of exchanging the energy contained in normally exhausted building air and using it to treat the incoming outdoor ventilation air in commercial HVAC systems. This process increases efficiency in commercial HVAC systems while reducing operating costs. During the summer months, the system will cool and dehumidify air entering the building with the “used” air leaving the building. Similarly, during the winter months, the HVAC system will warm and humidify the air using the same process.

The energy recovery ventilation process provides several key benefits. It allows the ability for an operation to meet the ventilation and energy standards set forth by the American Society of Heating, Refrigerating and Air-Conditioning Engineers, as well as improving the indoor air quality and reducing the HVAC equipment requirements and the loads placed upon the components within the commercial HVAC equipment.

This process is attained through the use of an energy recovery ventilator which is a type of air-to-air heat exchanger that transfers sensible and latent heat. The efficiency of this type of system is the ratio of energy transferred between the two air streams compared with the total energy transported through the heat exchanger. As with all manufacturers, specific efficiently ratings vary amount product, as well as location and application. Some systems have been shown to have heat exchange efficiencies as high as 70-80 percent, while others are as low as 50 percent. New technology is constantly being developed to increase efficiency ratings and each year new systems are introduced to the market. Check with your commercial HVAC specialist to see if your operation would benefit from an energy recovery ventilation system.
