Being accountable for proper airflow delivery causes a tech to examine every portion of an installation differently. Airflow is no longer assumed since test instruments now measure it. Let’s look at some of the most common obstacles to achieving a successful air balance on a residential HVAC system.
Originally designed to support an occupancy level of 850 people, the Arcbest corporate headquarters has grown to now have 1,085 people plus visitors. Ten percent of the people work at night, requiring 24/7 air conditioning. The increase in occupancy drove a need to introduce more outside air to maintain air quality. All of this outside air had to be conditioned, increasing electrical energy costs. In addition, the extra outside air caused draftiness on cold winter days, and, during the summer, the extra outside air flow through the air handlers resulted in some parts of the building getting too cool.
HLR technology achieves superior IAQ to boost student performance
April 25, 2017
enVerid Systems Inc. announced that the Shanghai-based China Europe International Business School (CEIBS) has achieved superior indoor air quality per the U.S. Environmental Protection Agency (EPA) standards, and 80 percent reduction in the utilization of outside air, through the installation of enVerid HLR® (HVAC Load Reduction) modules in its state-of-the-art lecture theater.
Though consumers are becoming more familiar with IAQ, it’s important for HVAC contractors to facilitate conversations that focus on indoor environmental problems and solutions and then let them make their own decisions.
As consumers become better educated about IAQ, the need for humidification and dehumidification — and the comfort solutions they provide — has increased. According to RnR Market Research, the global market for humidifiers is expected to surpass $1 billion by 2019. Another study, conducted by Grand View Research Inc., states the global dehumidifier market is expected to reach $3.54 billion by 2022.
Mold can be found everywhere, both indoors and outdoors. However, it’s usually not a problem until it begins growing indoors. According to the Centers for Disease Control and Prevention, exposure to mold can cause a number of health effects and symptoms, including allergic reactions, asthma, and other respiratory complaints. Mold can be a serious issue if left untreated, which is perhaps one of the reasons most HVAC contractors tend to avoid it.
While proper ventilation can sell itself for those who suffer from allergies, it can be a more difficult sell to the rest of the population. Many homeowners are more concerned with ensuring their HVAC system is keeping a consistent temperature than maintaining indoor air quality (IAQ). But, in recent years, more and more studies are linking health issues with indoor air pollution. By making homeowners aware of these results, you can help them make an informed decisions for proper ventilation and air quality improvements.
