1 ENERGY RECOVERY VENTILATORS MODEL RVX SERIES State-of-the-art Lossnay heat exchange technology, reduces CO and saves energy.

2 Indoor air quality inside a building is optimised through Lossnay is a total heat exchange ventilation system that uses paper characteristics to perform temperature (sensible heat) and humidity (latent heat) exchange. The concept of sensible heat and latent heat exchange using Lossnay core Outside Inside Outside exhaust air outlet () Inside return air (RA) Outside air intake () Inside supply air (SA) After launching its first generation in 97, Lossnay has evolved by always looking ahead of the air conditioning needs of the times, which continue to diversify. The technology is used in a wide range of applications and units have been widely adopted in residences, office buildings, hospitals, schools, etc.

3 temperature and humidity exchange by Lossnay The need for ventilation The need for fresh air Poor air quality can be attributed to many problems arising in the workplace and in the home. It is believed to contribute to a significant loss in productivity, low morale and higher rates of sickness. Providing good ventilation in residential and commercial buildings is to provide conditions under which people can live and work comfortably and safely.

4 Product Features Improved Air Volume Range Wide range air volume Unlike the air volume produced by previous models, in which there are the three settings of High, Low, and Extralow, the new model is equipped with four fan speeds. In addition, each speed has a range setting of 5, 5, 75 and %, allowing much finer air volume control. When used in combination with the CO sensor or timer function, the air volume can be controlled according to conditions that realize better performance and reduce power consumption. Previous model characteristic curves New model characteristic curves Static pressure Static pressure Offers a wide range of airflow variations, from fine to large volume Fine air volume operation is not available 5% 5% 75% % Extra Low Low High 3 4 control by CO sensor An external CO sensor can be connected directly to the Lossnay RVX units allowing the fan speed to vary according to the CO levels detected. When the CO concentration is low, the unit can operate at a lower air volume compared to previous models and this improves total heat exchange efficiency and contributes to energy saving. 4 4 High CO density COSensor Low CO density COSensor Weekly timer The operation pattern for each day of the week, ON / OFF and air volume can be set using the weekly timer function (up to eight zones per day). Compared to previous models, much finer operation control contributes to enhanced energysaving operation. With a wider range of air volumes the Lossnay RVX units enable optimised ventilation not just at different times of the day, but for different days of the week as well, enabling further energy savings.

13 Job Reference Office The reason for choosing Lossnay When it came to selecting a fresh air ventilation system for its new Head Office the company was well placed to select the best. Lossnay is an effective ventilation system that works alongside the City Multi Variable Refrigerant Flow (VRF) air conditioning that has also been installed, to provide employees with the optimum environment in which to work comfortably and safely. The merits of use The Lossnay technology reduces overall energy costs by extracting stale air from a room and recovering the heating or cooling energy from it ; this energy is then used to warm or cool incoming fresh air. Using recovered energy means that the system can save up to 3% on the initial capital costs of a heating and cooling plant. Lossnay s features The LGH Lossnay series offers a free cooling function and when the outdoor temperature is lower than the indoor air conditioned temperature, Lossnay will provide cool, fresh outdoor air to reduce the indoor air temperature therefore reducing the energy requirement and running costs. Installation Summary Application : Office Product : Lossnay LGH-R and LGH-5R units provide mechanical heat recover ventilation Results : The system recovers around 8% of wasted heat from the outgoing exhaust air Lossnay can work independently or alongside existing heating and cooling systems The units also offer a free summer cooling function

Inspection opening (45x45 or more) Remote controller (optional parts) Supply air grille (not included) SA RA (supply air) (return air) Return air grille (not included) Attention for specifications. Cold operation mode(*) is to start repeating in the case that Lossnay's detected temperature is less than-. *.Supply air(sa) in the operation for 6min. followed by stop operation for min.. The current, power consumption and efficiency are based on the air flow rate in the specification. 3. is selectable by the remote controller from fan speed,, 3 and 4. Multi Ventilation Mode should set on Lossnay unit or remote controller (PZ-6DR-E). 4. Lossnay ventilation mode is to start automatically in the case that Lossnay's detected temperature is less than +8,even if Bypass ventilation is set by remote controller. Remote controller continue to show "Bypass ventilation" in this case. 5. Temperature Exchange efficiency(%) are based on winter condition. 6. Mitsubishi Electric measures the machine according to the Japan Industrial Standards(JIS B 868) Attention. When using the product where it is exposed to high temperatures and humidity (4 or higher, RH 8% or higher), or where fog occurs frequently, moisture is likely to condense in the core, and may result in condensation build up in the unit.the product should not be used under such conditions.. Outdoor air may enter the Lossnay owing to the pressure difference between indoor and outdoor or external winds even when the product is not operated. It is recommended to install an Electrically operated damper to block the outdoor air. 3. In a cold weather area, an area with strong external winds or where fog occurs frequently, cold outdoor air, external winds or fog may be introduced into the product when its operation is stopped. It is recommended to install an Electrically operated damper. 4. In a cold weather area, or others, dewing or freezing could occur on the main unit, where the duct is connected, or other sections, depending on the conditions of outdoor air and indoor temperature and moisture, even if they are within the range of operating conditions. Make sure to confirm the operating conditions and other precautions, and do not use the product if dewing or freezing is anticipated. 5. The outside ducts must be tilted at a gradient (/3 or more) down toward the outdoor louvres from Lossnay, and properly insulated. (The entry of rain water may cause power leakage, fire, or damege to household property) 6. The two outdoor ducts must be covered with heat-insulating material in order to prevent condensation from forming. If it is expected that the ambient temperature around the place where the Lossnay unit is installed will be high during the summer air conditioning season, it is recommended that the indoor ductwork be covered with insulation material. 7. Inspection opening (45 45 or more)must be installed on the filter and Lossnay core removing side. 5
