Inexpensive, efficient HRV? - GreenBuildingAdvisor
2017年3月12日 · I just saw the posts about the Panasonic Intelli Balance 100 ERV. Does anybody make a similar HRV? Something with a price point under $1,000, good efficiency and at least 50+cfm airflow? A unit like that would make me reconsider an exhaust-only system. The closest I've found are the Braun HRV160 ECM units. --John
HRV with bathroom exhaust fan - GreenBuildingAdvisor
2010年9月20日 · For 2 of the 3 bathrooms, I would typically use a 110cfm PAnasonic Whisper Green fan because of the size of the room. So the HVAC sub feels like it will take too long running the HRV at full speed to adequately vent the space. A 50cfm Panasonic has a rating of 8.5cfm/watt while the Lifebreath is 1.5 cfm/watt.
DIY Low-Budget ERV/HRV Installation - GreenBuildingAdvisor
2021年7月21日 · Panasonic ERV and DIY ducting with rigid Ys instead of plenums and some flex duct mixed with more 4" rigid. The vents are adjustable in each room so I'll be able to balance a bit that way. I'm sure the Zehnder engineers are spitting their coffee on the screen reading that, but at 1/10th the cost it's the only way I can go on this build.
Panasonic Intelli-Balance 100 ERV With New Boost Function
2020年12月1日 · A lot of people know about the first generation FV-10VE1 Panasonic Intelli-Balance 100 ERV, as promoted by Matt Risinger. Like myself, many were disappointed to learn that this otherwise excellent […]
HRV v. ERV v. fan - GreenBuildingAdvisor
2011年1月5日 · I need an extra 57CFM / 24 hour continuous ventilation in my 1965 New Hampshire (Zone 6A) 1200 sq ft 2-level house, according to my blower door test. The energy auditor recommended the Panasonic Whispergreen. I asked if an HRV (or ERV) would save money & do the job instead, including venting 2 bathrooms which are looking a bit moldy …
Six Steps to Success With Heat-Recovery Ventilation
2018年1月29日 · Heat-recovery ventilators (HRVs) and energy-recovery ventilators (ERVs) remove stale air from the home and replace it (in winter) with preheated fresh air from outside. The result is better indoor air quality and lower energy use than in standard homes. The HRV itself is fairly simple: an airtight box with a heat exchange core that transfers heat from the …
Improving Smart-Tech Capabilities of an ERV
2023年12月4日 · @Tobym , you had me curious on adding a few more data points. Adding the actual watts for exchanged heat and added heat is interesting. You can really see the value in having a more efficient core in an HRV/ERV. I'm at 79% efficiency and recovering 567 watts in the HRV core, but still adding 147 watts to warm the air to room temps after the ...
HRV vs. ERV in Cold Climate - GreenBuildingAdvisor
2009年8月11日 · I'm looking for a small capacity HRV, the equivalent size of the Panasonic FV04VE1 which can be wired for 20/10CFM, since, as I've read in the installation details, at outside temperatures below 20F, the Panasonic ERV in question operates as exhaust only (and between 32 and 20F, operates in frost-prevention mode, cycling intake on and off).
Balanced Ventilation with HRVs and ERVs - GreenBuildingAdvisor
2021年10月8日 · In a heat-recovery ventilator, or HRV, there’s an exchange of thermal energy across the core. This is what engineers call “sensible heat.” In winter, exhaust air transfers some of its thermal energy to incoming fresh air, reducing much of …
ERV selection - GreenBuildingAdvisor
2017年3月26日 · Panasonic Intelli-Balance 100: self balancing ( this is important), highest efficiency on the martet at 50cfm, small proprietary filter, unknown price. Lower efficiency at 100cfm. RenewAire EV200: 200 cfm, high efficiency at 200cfm. Big filter, not self balancing. Fantech: cheaper and lower efficiency, not self balancing, small filters.
