As this air passes through the HRV it warms the plates of the heat exchanger core. This air is heated and dried by passing over the warmed heat exchanger plates. Supply and exhaust air streams never mix but heat energy is continuously exchanged between the two. An HRV is a controlled ventilation system that reduces high humidity, pollutants and odours by replacing stale air with fresh warm air. Exhaust air is not only stale and damp, but warm.
HEAT RECOVERY VENTILATOR: How to Install An HRV or ERV Yourself
HRV - both supply and exhaust ducted to furnace. Is this a good idea?
First up: Phase Space! One of the first things that he ever asked us was "Can you measure HRV with it? Our immediate answer was "Yes, of course! Well, we've had a few revisions of hardware and software since then, and the answer is still 'yes'. Most of us are used to thinking that our hearts beat at a fairly regular and predictable rate, and we refer to this as Beats Per Minute BPM. But BPM is really measured as an average of some beats over time. Nobody's heart clocks in at a truly steady and regular rhythm Unless you have a pacemaker, in which case your beat better be really super regular!
What does a HRV do?
All questions come from real people looking for real answers. Heat recovery ventilators are sometimes called heat exchangers, heat recovery air exchangers or just plain air exchangers. Regardless of the name, these pieces of equipment can do more to improve indoor air quality than anything else. That was the situation with my friend, Bryan. At least not until cold weather hit and condensation began trickling down our windows.
New Houses Don't Breathe As most people know, new houses are constructed to be air tight. Although this is far more efficient in terms of heating and cooling, it also causes problems with air quality since there is no circulation. Our industry has a solution to help prevent mold and moisture problems, and to improve indoor air quality. This is where HRVs come in. The air that is brought into the house gets passed through a screen at the exterior, then through a filter inside the unit, then through the HRV core, which is actually a heat exchanger.
