What is energy recovery ventilation (erv)?

-

 


Energy recovery ventilation (ERV) is one of the most energy efficient systems you can use with your HVAC control systems, especially in commercial buildings. When using a traditional HVAC control system, a large amount of the hot and cool air delivered to indoor spaces actually ends up outside via the air exhaust, the trash exhaust, and the bathroom vents, resulting in a lot of wasted air. ERVs, which continue to grow in popularity, recover some of the energy from the airstream delivered outdoors.

ERVs connect to the ducts that are part of your existing HVAC systems, so they’re easy to install and don’t require much additional equipment. They also reduce the strain on your heating and cooling systems, and during the hot summer months ERVs can dehumidify and pre-cool your air supply before it enters your indoor space. Conversely, during the cold winter months, ERVs pre-heat the air by extracting heat from the warmer exhaust air before it’s expelled outside.

One thing many people don’t consider is the indoor air quality within their space. You spend the vast majority of your time indoors, so you may be surprised to know that according to the EPA, indoor air often contains two to five times more pollutants than outdoor air. Many of us assume that indoor air is cleaner than outdoor air due to air filtration systems, but contaminants easily slip through many air filters. ERVs remove contaminants, pollen, allergens, and pollutants from your air, ensuring your air supply is as clean and healthy as possible, and for commercial spaces this is essential. 

Benefits of using ERV with an HVAC control system 

As mentioned, ERVs may not be very widely-known yet, but they are continuing to grow in popularity as people discover their many benefits. Some of the key benefits include:

  • Reducing strain on your HVAC system, and because your air conditioners won’t have to work so hard, you’ll enjoy lower energy bills year round.
  • Making your HVAC system more energy efficient, which is important as we all find ways to make our personal environmental footprint smaller
  • Reducing unpleasant odors that can come from kitchens, bathrooms, and other areas. For restaurants, bars, shopping malls, schools, and other commercial spaces this is an essential benefit, because unpleasant odors can drive people away and make the environment very uncomfortable. 
  • Keeping the temperature consistent from room to room. Once you find your ideal indoor temperature setting, ensure all the rooms remain at this comfortable temperature throughout.
  • Filtering and removing contaminants from the air that may not be caught by your air filtration system. For people with asthma, allergies, and other respiration issues, breathing air that contains pollen and other allergens can cause problems. ERVs improve air quality and keep everyone breathing easier. 
  • They are quiet and require minimal maintenance and upkeep.

In addition to all the benefits listed above, ERVs help keep your space cleaner because they reduce the build-up of dust and other contaminants. Maintaining a clean environment in commercial spaces is crucial, and when you have an ERV system you’ll notice that your space doesn’t get dusty as quickly as it used to, so you won’t have to dust and wipe down surfaces as frequently as before.

Professional Boiler Services Keep Your Business Running Smoothly

A proper heating system is essential for every commercial building, including factories and industrial sites, and having the correct  boiler system installed  and maintained by specialists is key to operational efficiency and minimal downtime. But all commercial Boiler service companies are not created equal. Levels of expertise, experience, access to specialized equipment, responsiveness, and integrity when considering repair or replace, are also critical. What to look for in your commercial boiler contractors  Commercial and industrial experience:  If you need an existing system maintained, repaired or upgraded, or a new system built from the ground up, residential boiler specialists simply won’t be able to help you – you need a partner who understands the demands of commercial heating systems. This is because scale isn’t the only factor at play – commercial systems have to work harder, have a role beyond just heating in many businesses, and often requi...

Common HVAC Pump Problems And Their Solutions

-
Image
Hydronic pumps are a critical part of your commercial HVAC system’s operation, keeping your building cool in summer and warm in winter. Here are some of the most common problems with this unit that we’ve dealt with at our  commercial HVAC company in NJ,  and how to solve them. Cavitation:  This occurs when there is too much air in the liquid that flows through the system and can lead to increased wear-and-tear of the pump and damage to the impeller. Vibration: Excessive vibration can be caused by out-of-balance equipment, bad bearings, an unbalanced rotor, bent shaft or a clogged impeller. The pump will have to be checked as it may have worn out, or your system will require lubrication, replacement bearings, impeller adjustment or an adjustment of the flow speed. The pump is too big: HVAC equipment is often selected without considering the size of the area the system is servicing. An oversized pump will start up and shut down more than it is designed to do beca...
