Fresh air\u2014everybody wants it, but they don\u2019t know how to get\nit when they need to have the windows and doors of their homes closed against\nthe Florida heat and humidity. We know a great way you can have the fresh air\nyou want without the heat and humidity problems. It\u2019s an energy recovery\nventilator, a nifty installation for your HVAC system that draws fresh air into\nthe house and pre-cools it.<\/p>\n\n\n\n

Energy recovery ventilators have a name people find a bit confusing. What \u201cenergy\u201d is the ventilator recovering, and how is this helpful for fresh air? Answering questions like this is why we have a blog! So, it’s time for some science. (Light science, don\u2019t worry!)<\/p>\n\n\n\n\n\n\n\n

The Energy Used to Cool Your House<\/h2>\n\n\n\n

How do you cool your house during the summer? With an air\nconditioner, of course. What\u2019s the energy source for the air conditioner?\nElectricity. That\u2019s our starting point for this story. You pay money in\nelectrical watts to run the air conditioner. I.e. you pay for the energy to\nremove heat from your house with the AC. <\/p>\n\n\n\n

Now, what happens if you open the windows and doors on a 90\u00b0F day when the AC is running? The air conditioner will have to run and run and run to keep up with the outside heat that floods in. And that means energy is wasted<\/em>.<\/p>\n\n\n\n

Now we turn to the hero of our story, the energy recovery ventilator\n(ERV). The ERV is installed inside the ventilation system, and it draws a\ncurrent of fresh outdoor air into it; at the same time, it draws in a current\nof the indoor air. The indoor air is cooled down: energy has already been used\nto remove the heat from it. It moves past the current of incoming fresh air\u2014and\nthe fresh air loses its heat to the cooler incoming air. The fresh air enters\nthe home, cooled down. Or, to put it another way, the incoming air recovered<\/em>\nthe energy originally used to cool down the air inside. <\/p>\n\n\n\n

(And, as a bonus, moisture moves between the two currents.\nThe humid outdoor air loses moisture to the indoor air, meaning the house receives\nair that\u2019s been dehumidified.)<\/p>\n\n\n\n

It Works in Reverse as Well<\/h2>\n\n\n\n

An ERV can also recover the energy used to heat the air in a house during colder weather and apply it to incoming colder air. The process is exactly the same. This isn\u2019t as important a job in our warm climate, but it\u2019s still helpful\u2014the ERV can work for you all months of the year.<\/p>\n\n\n\n

There\u2019s a similar device to an energy recovery ventilator\ncalled a heat recovery ventilator (HRV). These are almost never installed in\nFlorida, however, since they\u2019re designed to operate in colder temperatures, and\nthey do not affect high humidity. <\/p>\n\n\n\n

We\u2019re the local St Petersburg, FL, HVAC contractor<\/a> who can outfit your house with the right ERV system so you can enjoy fresh air all year without seeing your HVAC energy bills go skyrocketing. We\u2019ll help recover<\/em> that energy and put it to use!<\/p>\n\n\n\n
