Considering Zoning Your Commercial HVAC?

Posted by Ohio Heating

Nov 29, 2021 6:45:00 AM

Just a few of the reasons to consider zoning your commercial HVAC includeZONING rev_COMMERCIAL-1 saving thousands of dollars in energy costs as well as improving the comfort of your occupants. 

Many light commercial buildings, offices, hotels, museums, and schools have only one thermostat and one HVAC system controlling multiple rooms, floors and offices. This can waste a lot of energy and provide inconsistent temperatures throughout the property.

Zoning your commercial building can provide temperature control for areas as large as an entire floor of your facility, or for smaller room-size areas. They can be installed to work with existing or new commercial HVAC systems to split the building into zones.

The zones are determined by factors such as the usage of each space, number of occupants and construction type.  They let you set temperatures in each area without impacting conditions across the building. 

When integrated with variable speed and/or two-stage HVAC systems, zoning your heating system allows your equipment to deliver peak performance and efficiency without continually operating at peak capacity. Lower speeds also mean quieter operation.

Benefits of Zoning:

Consistent Heating & Air Conditioning. Should an area need more heat or AC the thermostat for that area can be adjusted.  Empty offices or rooms can be adjusted. 

Custom Temperature Control. Zones in your property can be heated or cooled to accommodate the occupants. This can improve productivity.

Lower Energy Bills.  A properly designed system can reduce the cost of heating and air conditioning the facility by as much as 35%. 

At Ohio Heating & Refrigeration, we can design a system that will provide a comfortable and healthy indoor environment for your entire building.

Improve the Comfort of Your Warehouse Space

Posted by Ohio Heating

Oct 11, 2021 11:00:00 AM

Heating or air conditioning your warehouse, workshop, or other commercial building can be a challenge when dealing with high ceilings.  A 0.5 to 1-degree heat rise occurs with each elevated warehouse space_s foot within your building. If you have a 20-foot ceiling, there can be a 10 to 20-degree difference in the temperature between the floor and the ceiling.

During the colder months, the coldest air usually stays at the lowest point or floor level, where most employees are located. If you are trying to heat your building, the heated air rises to the ceiling and the colder air stays on the floor, making it uncomfortable for workers. To maintain temperatures at the lower levels where most thermostats are located, the system has to work harder.

When trying to air-condition the space during warmer months, maintaining temperatures at floor level may require that ground level spaces be too cold when the space has a mezzanine level.

A big issue to resolve in these spaces is thermal stratification. When the cool air is met with the heated air in the ceiling, it  negates the effect of the cooling process. This problem can be solved by using a combination of exhaust fans, air intake fans and air circulator fans. By moving the air, both at the floor and the ceiling levels, you can heat or air condition the space efficiently.

The overheating and overcooling that is required to overcome stratification in buildings with high ceilings not only causes a decrease in comfort levels but also wastes energy. Estimates of the annual energy savings can be as high as 15-20% when the effects of stratification are reduced.

Commercial Ventilation Systems

Posted by Ohio Heating

Sep 1, 2021 6:30:00 AM

The circulation of air throughout a building is ventilation. The ventilation of a commercial property relies heavily on the HVAC system. A good HVAC system should provide air to building occupants at a comfortable Ventilation system 2020-1 temperature, at comfortable humidity levels and be free of harmful concentrations of air pollutants.

Improper operation and maintenance of HVAC systems are the most common problems that impact workplace indoor environmental quality (IEQ). 

The heating & air systems serve to dilute and remove contaminants from occupied areas, such as:

  • carbon dioxide and carbon monoxide
  • tobacco smoke
  • molds and bacteria
  • cleaning products
  • copy machines and printers
  • pesticides
  • vehicle exhaust

There are three basic elements to building ventilation:

 1. Ventilation Rate. The amount of outdoor air that is provided into the space, and the quality of the outdoor air 

 2. Airflow Direction. The overall airflow direction in a building, which should be from clean zones to dirty zones

 3. Airflow Pattern. The external air should be delivered to each part of the space efficiently and the airborne pollutants generated in each part of the space should also be removed efficiently.

Mechanical ventilation that is driven by fans and hybrid ventilation systems are the most common types of ventilation in Central Ohio.

With mechanical ventilation, fans can either be installed directly in windows or walls, or installed in air ducts for supplying air into or exhausting air from a room.

The type of mechanical ventilation used depends on the climate. In cold climates, exfiltration needs to be prevented to reduce interstitial condensation, and negative pressure ventilation is used. For a room with locally generated pollutants, such as a bathroom, toilet or kitchen, the negative pressure system is often used. In a negative pressure system, the room is in negative pressure, and the room air is compensated by “sucking” air from outside.

Hybrid ventilation relies on natural driving forces to provide the desired flow rate. It uses mechanical ventilation when the natural ventilation flow rate is too low.

If natural ventilation alone is not suitable, exhaust fans can be installed to increase ventilation rates. This type of hybrid (mixed-mode) ventilation needs to be used with care. The fans should be installed where room air can be exhausted directly to the outdoor environment through either a wall or the roof. The size and number of exhaust fans depend on the targeted ventilation rate and should be measured and tested before use.

The use of exhaust fans can have issues such as difficulty installing large fans, noise especially from high-power fans, increased or decreased temperature in the space and the need for a non-stop electricity supply. If the environment in the space causes thermal discomfort, spot cooling or heating systems and ceiling fans can be added.

Use Your HVAC to Control Mold in Commercial Property

Posted by Ohio Heating

Aug 18, 2021 5:30:39 PM

Mold is very common in buildings, something commercial property managers often have to deal with. It can cause discomfort and irritation for the building’s occupants while mold solutions compromising indoor air quality if ignored.

Your HVAC system is an important component in controlling mold growth in your commercial property and preventing its spread. An experienced HVAC contractor, like Ohio Heating & Air, can help you deal with the problem. 

Mold forms under specific conditions. It needs water, a food source and the right temperature.  A commercial property's drywall, carpeting, wood and furnishings can be a source of food for mold. Mold also grows well on paper products, cardboard, and ceiling tiles. Excess moisture or dampness caused by relative temperatures can encourage mold development, as well as moisture from flooding or leaks.

Research has found that people who spend time in damp buildings are more likely to report health problems such as these:
 • Respiratory symptoms (such as in nose, throat, lungs)
 • Development or worsening of asthma
 • Hypersensitivity pneumonitis (a rare lung disease caused by an immune system response to repeated  inhalation of sensitizing substances such as bacteria, fungi, dust, and chemicals) 
 • Respiratory infections
 • Allergic rhinitis (often called “hay fever”)
 • Bronchitis

Your HVAC system can have a big impact on the indoor moisture level of your commercial property. If the system isn't operating properly, not only will it generate moisture that promotes the growth of mold, but it can also spread the mold spores through the ductwork.

Tips to Battle Mold in Your Commercial Building:

1. Check the drain pans. Make sure the drain pan is properly cleaned and sloped to prevent mold buildup.
2. Use the ventilation and dehumidification equipment. Excessive indoor moisture in your property promotes mold. Ohio Heating & Air offers a wide range of ventilators and dehumidifiers from top manufacturers such as Bryant® to meet your needs.
3. Invest in regular HVAC tune-ups and maintenance. An HVAC system can become wet or develop issues that lead to mold growth. Outdoor air dampers, ducts and air filters can all add to mold issues.
