LG ventilation solution ERV is an efficient solution for fresh indoor air. A variety of energy-saving technologies and air purifying filters allow you to breathe healthier air.
LG Ventilation Solution Commercial ERV installed outside of a building. The airflow from the office is connected to the ERV, facilitating circulation.
Natural ventilation can waste energy, but LG ERV provides fresh air from outdoors and reduces polluted indoor air. The ERV saves energy with its heat exchanger, which loses virtually no heating or cooling energy.
Air, carrying bacteria, circulates from a snowy exterior into a room on the left. On the right, an ERV system captures these bacteria.
ERV works in conjunction with an indoor unit to save energy by operating more efficiently than a ventilation system alone.
LG indoor unit and two ducts on the ceiling, viewed from the side, draw air from the right duct while the other two units expel air into the area.
ERV offers many energy-saving technologies. The heat exchanger saves up to 24% more energy than natural ventilation, and works with other features to provide total energy savings of up to 40%.
LG ERV senses the outdoor temperature and adjusts operation according to the weather conditions, saving 6.1% more energy annually.
LG ERV exhausts indoor heat and supplies cool outdoor air indoors on summer nights to save 5% more energy annually.
*’Automated Seasonal Operation’ on remote control.
*‘Night Time Free Cooling’ function on remote control.
LG ERV reduces energy loss by 4.6% annually with automatic fan speed control that adapts to CO2 levels.
LG ERV saves reduces heating and cooling energy loss by 0.9% annually by delaying ERV operation so that the air conditioner and ERV operate simultaneously only when necessary.
*’Suspended Operation’ function on remote control.
*Based on an LGE internal simulation of an LG air conditioner and LG ERV operating together, the heat exchanger saves up to 24% more energy than natural ventilation and works with other LG ERV features to provide total energy savings of up to 40%. Results may vary depending on the environment. Simulation Conditions: Based on ERV (1,000CMH) + Multi V 5 (12hp) / 455m2 office space, Cooling 26℃ / heating 21℃, e Quest 3.65 / Daily operation in winter conditions.
A CO2 sensor monitors CO2 levels in the room. The CO2 level is continuously displayed on the screen of the wired remote control, and an alarm indicator appears when levels exceed 900 ppm. The ERV uses this information to automatically control fan speeds.
A circular ceiling duct blows airflow over couches while a wall mounted control panel shows CO2 level and temperature.
* A CO2 sensor accessory is required.
By installing a basic filter on the front of the total heat exchanger and an ISO grade filter behind the total heat exchanger, inflow of fine dust and pollutants from outdoors is reduced.
*ISO rate air filter is optional.
Green airflow passes through a basic filter, heat exchanger, and ISO-rated air filter from left to right, getting cleaned.
*ISO rate air filter is optional. ISO rating according to ISO 16890:2016.
*The air filter (Model number : AHFT035H0) performance was tested by an ISO 16890-1:2016 Air Filter Test by using DEHS and KCl aerosol with the condition of air flow rate of 0.278 m³/s, air temperature of 23-24 °C and relative humidity of 44-49%. The result was an ISO rating of ePM1 75%. Results may vary depending on the environment.
LG ERV DX has humidification and dehumidification functions, making it a good match for spaces where you need both temperature and humidity control. Humidity can also be monitored through the wired remote control.
An LG ceiling cassette and circular duct blow airflow into an office while the controller displays humidity and temperature.
If dust clogs the filter, an alarm that informs you that the filter is contaminated appears on the remote control screen. You can then replace the filter based on actual contamination levels.
Wall mounted controller on the left display the error message. Zoomed error message displayed on the center telling the filter need to be changed.
Three white circles from left to right depict outlines of a residence (apartment), an office, and a public facility like a school or commercial area.
LG Commercial ERV lineup chart includes with Humidifier, and without Humidifier, detailing model type, Btu/h, and kW.
