2016年10月23日 · One RTU per theater and one (or more) ERVs to handle the outside air separate from the space load seems to be the way to go. Variable volume outside air based on CO2 or something might be a good long term energy savings, but harder to justify the added cost.

RenewAire Engineered Combo Curbs easily combine Trane Rooftop Units with our Energy Recovery Ventilators (ERVs). They eliminate the need for transitional ductwork between the RTU and the ERV, reducing the time and costs of installation.

Greenheck offers a complete line of energy recovery ventilators to reduce a building’s tempering loads for all climates. From outdoor, roof-mounted applications to indoor, ceiling-mounted units, Greenheck preconditioners offer installation flexibility for …

With regulations placing more and more emphasis on both outside air ventilation and energy efficiency, adding an Energy Recovery Ventilator (ERV) to an HVAC system can help meet outside air demands while saving energy at the same time.

2020年6月12日 · Although ERVs can be expensive, with the reduction in RTU size (which typically includes a boost in efficiency), pay backs can be as little as 3-5 years. Worth mentioning here – an ERV may be required by code for your project. Below is a snapshot from the 2018 International Energy Conservation Code (IECC).

IAQ sized unit - An IAQ sized ERV has an ERV that is sized to handle approximately 10% of the outside air that the RTU is normally recirculating. If you have a 10 Ton RTU, the RTU is normally recirculating about 4,000 CFM (RTU’s are normally designed around 400 CFM/ton). The iAIRE ERV would be sized to bring in approximately 400 CFM into this

ERV should be wired in parallel with the controls with "G" to 1, "C" to 2 and "W" to 3. The ERV will operate when ever the RTU's blower is operating. Energy Management: Building Management Systems: The ERV needs a 24 Volt AC signal to operate, connect the 24V+ to 1 and the 24V C to 2, the unit can be operated

2015年10月6日 · These Energy Recovery Ventilators (ERVs) are used in a side discharge manner equipped with a field provided balancing damper assembly through ductwork on the roof. A roof curb must be provided by contractor to manufacturers specifications.

iAIRE ERV’s use integrated controls that control the ERV & economizer operation along with the RTU, allowing for the most cost-effective operation of the unit. The patent-pending iAIRE technology allows for IAQ sized ERV wheels, along with ionization, to be 1/3 the size of a …

the ERV should be wired in parallel with the controls with "G" to 9, "C" to 10. The ERV will operate whenever the RTU's blower is operating. If the system the ERV is being attached to has a separate blower speed for Heat, a relay will have to be set up to switch between W and G outputs from the RTU/AHU to terminal #9 on the ERV.
