3. Features & Benefits The LG heat recovery ventilation system, improving your indoor air quality.

, is the solution for

Ventilation is a process by which one can exchange indoor air to outdoor air in order to improve the air quality and to maintain environmental temperature conditions. With todayâ&#x20AC;&#x2122;s concern for a healthy indoor environment, is an integral component of HVAC system. Using in the HVAC system allows contaminants to be removed quickly and effectively from the airconditioned space. A balance is thus achieved between indoor and outdoor ambients, enabling the cooling or heating load on the air conditioning system to be reduced significantly. Low-noise Design

Energy Savings

is accoustically engineered and tested for quiet operation. (ensuring comfort to be felt, not heard.)

The indoor air is passed through the heat exchanger to prewarm or precool the incoming outside air, saving energy and money.

Air Purifying

Easy Maintenance

Removing common pollutants from home which create an unhealthy environment.

The briefcase-style latches allows easy filter replacement and heat exchanger cleaning.

Efficiency & Comfort exhaust the polluted indoor air to outdoor and supply the fresh outdoor air to indoor in order to maintain the residentâ&#x20AC;&#x2122;s healthy and comfortable indoor environment.

3. Features & Benefits Healthy and Fresh Indoor Environmental Maintenance : Case of the window ventilation

(Indoor) 30˚C 26˚C

(Outdoor) EA

30 C

In order to ventilate the indoor air is to open the window in summer. While opening the window, the conditioned indoor air goes out. Indoor air has to be cooling again.

Case of Enthalpy heat exchange ventilation

26˚C

When using the enthalpy heat exchanger,it maintains the temperature and humidity of the indoor and changes the polluted indoor air to the fresh outdoor air.

• Comparing to Enthalpy heat exchange ventilation with the window ventilation,Enthalpy heat exchange enables to economize a electric bill.It also helps the environmental protection due to saving energy.

Enthalpy Heat and Sensible Heat Exchangers Comparisons : • Enthalpy Heat Exchanger = Temperature heat (temperatures) + Latentheat (humidity)

• Sensible Heat Exchanger = Temperature heat (temperatures)

• The Enthalpy Heat Exchanger consists of Mechanism which is exchanged to the temperature heat (temperatures)as well as the latent heat (moisture heat capacity).When it calculates at the electric heat frequency quantity,it has an energy recovery effect above 3 times than the temperature heat.

â&#x20AC;˘ Like appearing from the picture of the case only of the temperature heat exchange,the efficiency is high. But when it calculates at enthalpy heat frequency quantity,it has a difference above 3 times.

Zero Standby Power Consumption :

5~6W

- Due to SMPS (Switching Modulation Power Supply) technology, there is almost zero power consumption in the standby mode. It saves energy and cost.

0.5W Others

3. Features & Benefits High Efficiency Heat Exchanger : - Cross flow heat exchanger ensure no mixing of the stale air with the fresh air. Efficiency and comfort is ensured by the high-efficiency energy recovery central core which recovers energy from the indoor air and transfers it to the fresh incoming air without mixing airstreams.The heat exchanger also helps to remove unwanted humidity from air inside your home during winter, and removes the humidity from the outside air before it enters your home in the summer.

:(External Static Pressure Control) E.S.P Control M

L Air volume

- Individual air volume control (Supply&Exhaust). Generally, when External Static Pressure increases air volume decreases. But by controlling the phase of motor E.S.P. is controlled linearly. E.S.P. control provides required constant air volume irrespective of E.S.P. change. Desired E.S.P. can also be set through LCD wired remote. Setting of the desired E.S.P. gives required combination of ESP and airflow. So, air volume is kept constant for various duct work system. All units feature Phase control of Motor.
