Nowadays, when energy efficiency and indoor air quality are so key, Energy Recovery Ventilation (ERV) is a game changer. Have you wondered: how an ERV reduces Air Conditioner load? So why is ERV/HRV (Energy Recovery Ventilation or Heat Recovery Ventilation ) better than TFA (Total Fresh Air)?
It’s easy enough to break it down in an understandable and actionable way.
Energy recovery ventilation (ERV) – The Power.
What if there was fresh air indoors without raising your energy bills? That’s where ERV systems come in. Not only do these systems bring fresh air into your space, but they also condition that air before it gets there, playing a significant role in helping reduce the work your air conditioner is required to do.
How Does ERV Work?
1. Heat Transfer: ERV systems bring on and off some incoming fresh outdoor air and outbound some of the outgoing indoor air. In the summer, the ERV cools the hot outside air that comes in, and in the winter it warms the cold outside air. It reduces dependence on heating and cooling systems, thus lowering an overall energy load.
2. Moisture Exchange: ERV systems also transfer moisture in addition to regulating temperature. Throughout the summer, they lower humidity in the newly arriving air, which takes less strain off the air conditioning system. They bring moisture into dry air in winter without creating uncomfortable dryness or the added burden of extra humidifiers.
3. Fresh Air Circulation: Good indoor air quality requires a continuous supply of fresh air indoors, and ERV systems provide it. Such constant exchange of air makes sure that your living or working space remains fresh without needing additional mechanical cooling or heating.
ERV Reduces Air Conditioner Load: Why?
1. Minimizing Temperature Shock
What Happens: Sudden temperature change inside can be brought about by unconditioned fresh air forcing your air conditioning system to work harder.
ERV Solution: ERV systems help to pre-condition the incoming air thus preventing these temperature shocks and allowing your HVAC to stay in a comfortable stable indoor climate with less work.
2. Reducing Humidity
What Happens: Indoor spaces are uncomfortable due to excessive humidity and increased use of air conditioners dehumidification.
ERV Solution: ERVs achieve indoor/outdoor humidity balance, offloading part of the air conditioner burden. It prevents over dehumidification, saving energy.
3. Fresh Air Without Extra Work
What Happens: Traditional systems bring in fresh air, but with dehydration of the air conditioning, the fresh air may make it run harder because its temperature and humidity controls require adjustment.
ERV Solution: ERV systems precondition the fresh air, meaning your air conditioning system doesn’t have to work as hard to bring the air to the desired temperature and humidity levels.
4. Continuous Air Exchange
What Happens: Because your HVAC system will have to work harder to supply the same air quality and comfort, it needs air to be replaced constantly.
ERV Solution: ERVs help ensure continuous fresh air circulation, maintain good air quality, and reduce strain on the HVAC in that breathing uncontaminated air isn't something that we don't need to adjust or correct.
5. Energy Savings and Efficiency
What Happens: Air conditioning that constantly changes temperature and humidity uses more energy as compared to traditional ones.
ERV Solution: ERVs also work to condition the air before it even enters your building, saving your HVAC system lots of energy and translating into big cost savings.
6. Extended HVAC System Lifespan
What Happens: Excess temperature and humidity fluctuations will overburden your HVAC system over time.
ERV Solution: In contrast, ERVs precondition incoming air, namely air that passes through the environmental repair itself, thereby reducing the load on HVAC systems, extending their life, and decreasing the frequency of expensive repairs.
Conclusion
Pre-conditioning fresh air, minimizing temperature swings, and balancing humidity are key benefits that ERV systems bring to help reduce air conditioner load. They make your HVAC system last longer and boost energy efficiency, as well as your indoor air quality. ERVs are an economical alternative to reducing energy use and maintenance costs while keeping a comfortable, energy-efficient space.
