Yes. Depending on the building layout and the selected model, an ERV may be suitable for retrofit projects as well as new construction.

Is an ERV noisy? Is an ERV noisy?

ERVs contain fans and moving air, so some operating noise is unavoidable. The perceived noise depends on fan speed, unit design, installation quality, duct sizing, airflow velocity, vibration isolation, and the location of the unit.

Where should an ERV be installed? Where should an ERV be installed?

The installation location depends on the ERV model, building layout, duct routing, outdoor air intake and exhaust locations, and access requirements.

How do I choose the right ERV for my home? How do I choose the right ERV for my home?

Start with the required ventilation airflow, then evaluate the unit's delivered airflow at the planned external static pressure, recovery performance, filtration, sound levels, dimensions, power consumption, controls, and maintenance access.

Does an ERV provide clean air without opening windows? Does an ERV provide clean air without opening windows?

An ERV can provide a controlled supply of outdoor air while reducing the need to open windows solely for ventilation.

Can an ERV remove PM2.5, dust, and pollen? Can an ERV remove PM2.5, dust, and pollen?

An ERV can reduce incoming airborne particles when equipped with suitable filters. Its effectiveness depends on the filter's tested efficiency, the particle size, sealing, airflow, and filter maintenance.

Can an ERV reduce indoor CO₂ levels? Can an ERV reduce indoor CO₂ levels?

An ERV can help reduce indoor carbon dioxide (CO₂) concentrations by replacing CO₂-rich indoor air with outdoor air, provided that the outdoor airflow and air distribution are adequate for the occupancy.

How much fresh air does a home need? How much fresh air does a home need?

Required outdoor airflow depends on the applicable building code, occupancy, floor area, room use, and the ventilation design standard used for the project.

Is an ERV suitable for hot and humid climates? Is an ERV suitable for hot and humid climates?

An ERV can be part of a ventilation strategy for hot and humid climates, but the design must account for both heat and moisture loads.

Yes. An appropriately designed ERV can operate in both heating and cooling seasons.

Can an ERV control indoor humidity? Can an ERV control indoor humidity?

An ERV with an enthalpy exchange core can transfer moisture between incoming and outgoing air streams. This may help moderate indoor humidity, but it does not actively remove moisture in the same way as a dedicated dehumidifier.

Does an ERV save energy? Does an ERV save energy?

An ERV can reduce the energy required to condition outdoor ventilation air by recovering part of the heat and, where applicable, moisture from the exhaust air.

What is the difference between an ERV and a standard exhaust fan? What is the difference between an ERV and a standard exhaust fan?

A standard exhaust fan removes indoor air but does not normally recover energy from it. Replacement outdoor air must enter through designed inlets or other openings, and its temperature and moisture can add to the building's heating or cooling load.

An HRV (Heat Recovery Ventilator) primarily transfers sensible heat between incoming and outgoing air. An ERV (Energy Recovery Ventilator) can transfer sensible heat and moisture when equipped with an enthalpy exchange core.

How does an ERV system work How does an ERV system work

An ERV draws outdoor air into the building and exhausts stale indoor air through separate air passages. Inside the energy recovery core, heat and moisture can transfer between the two air streams without intentionally mixing the bulk air streams.

What is an Energy Recovery Ventilator (ERV)? What is an Energy Recovery Ventilator (ERV)?

An Energy Recovery Ventilator (ERV) is a mechanical ventilation system that supplies outdoor air and exhausts stale indoor air while transferring heat and, in enthalpy recovery systems, moisture between the two air streams.

What is the difference between an ERV and a dehumidifier? What is the difference between an ERV and a dehumidifier?

An ERV primarily provides controlled ventilation and energy recovery. A dehumidifier primarily removes moisture from indoor air.

Can an ERV control indoor humidity? Can an ERV control indoor humidity?

An ERV can transfer moisture between incoming and outgoing air depending on its core technology and operating conditions.

What is the dew point? What is the dew point?

The dew point is the temperature at which air becomes saturated with water vapor.

Why does radiant cooling need humidity control? Why does radiant cooling need humidity control?

Stable Humidity → Lower Dew Point → Safer Radiant Cooling Operation

Can air conditioning remove humidity? Can air conditioning remove humidity?

Yes, conventional cooling systems can remove some moisture when the cooling coil temperature is below the air dew point.

What is the difference between temperature control and humidity control? What is the difference between temperature control and humidity control?

Temperature → Sensible Load Humidity → Latent Load

Why is indoor humidity important? Why is indoor humidity important?

High humidity can make a room feel warmer and less comfortable even when the air temperature is within a conventional comfort range.

What is dehumidification? What is dehumidification?

Dehumidification is the process of removing excess moisture from indoor air.

How many modes of Menred G3 ventilator can be set? How many modes of Menred G3 ventilator can be set?

Energy saving mode: The air volume of exhaust air and fresh air are equal. Default wind speed is low speed. Haze removal mode: The fresh air is high speed, the exhaust air is low speed, and the wind speed shows high speed. Sleep mode: Both fresh air and exhaust air are low speed, wind speed shows low speed. Auto mode: Automatically adjust the airflow level according to the indoor CO2 and PM2.5 concentration. User can set the corresponding value in the setting page. For example, when PM2.5 is set to High > 100 > Medium > 35 > Low and C02 is set to High > 1500 > Medium > 700 > Low, when the air quality sensor detects PM2.4 > 100 and CO2 is between 700 and 1500, the wind speed is high.

what is an enthalpy exchanger what is an enthalpy exchanger

Enthalpy exchangers are particularly useful in climates where there are significant temperature and humidity differences between the indoor and outdoor environments. Apart from transferring sensible heat (temperature), they also transfer latent heat (moisture) between the airstreams, providing the benefits of both heat and moisture recovery.

If the area of a computer room is 60 sq meter(S=60), the net height is 3 meters(H=3), and there are 10 persons(N=10) in it. If it is calculated according to “Personal fresh air consumption”, and assume that:Q=70, the result is Q1=N*Q=10*70=700m³/h If it is calculated according to “Air change per hour”, and assume that: P=5, the result is Q2=P*S*H=5*60*3=900m³/h Since Q2＞Q1，Q2 is better for selecting the unit. As to special industry such as hospitals(surgery and the special nursing rooms), labs, workshops, airflow required should be determined in conformity with regulations concerned.
