LOSSNAYSYSTEM Lossnay ventilation systems are renowned industry-wide for their efficiency. They offer environment-friendly energy recovery and humidity control, and enable air conditioning systems to simultaneously provide optimum room comfort and energy savings. Indoor Air Quality Inside a Building is Optimised Through and Humidity Exchange by Lossnay Lossnay is a total heat exchange ventilation system that uses paper characteristics to perform temperature (sensible heat) and humidity (latent heat) exchange.

Commercial Use Lossnay LGH-RVX (Standard model) Power consumption reduced further with introduction of a DC motor Realized low power consumption with introduction of a high efficiency brushless DC motor. Compared to models with an AC motor, power consumption is reduced. Comparison between new and previous power consumption (New model: 4 at 2V Hz, Previous model: Extra-High at 22V Hz) (W) (W) 5 4 4 Improved Air Volume Range Wide range air volume Each fan speed has a range setting of,, 75 and %, allowing much finer air volume control. When used in combination with the CO2 sensor or r function, the air volume can be controlled according to conditions that realize better performance and reduce power consumption. adjustment function The default fan speed value can be adjusted slightly. Use the PZ-6DR-E remote controller to reset the speed. ) Considering the total hours of Lossnay operation (filter clogging), the fan power can be adjusted automatically after a given period of. 2) After the unit is installed, when if the air volume is slightly lower than the desired airflow, it is possible to make fine adjustments.

OA (Outdoor air) Fresh, outdoor-air in a quantity required for ventilation is drawn in by the supply fan. EA (Exhaust air) Heat from the indoor air (both sensible and latent) is recovered by the Lossnay core and vented outside by the The exhaust fan exhaust fan. High efficiency filters (Option) The supply fan Heat recovery unit (Lossnay core) and humidity are exchanged between the supply air and the exhaust air. Maintenance cover Air filter Prevents clogs in the Lossnay core. Dx-coil Cools or heats the drawn in outdoor-air. RA (Return air) The exhaust fan draws in contaminated indoor-air.

The running current and input power are based on 2V/Hz. 2. The cooling and heating capacities are based on the air conditions listed below and the rated airflow of fan speed 4. Indoor: 27 CDB/9 CWB Outdoor: 5 CDB/ CWB Indoor: 2 CDB/5 CWB Outdoor: 7 CDB/6 CWB. The first figure in ( ) of the capacity specification is the heat recovery energy of the Lossnay unit. The second figure is the capacity specification for the Dx-coil connected to the outdoor unit. 4. Performance index is the calculated value at the temperature conditions above and is reference purpose only. Performance index = Total capacity total power consumption of outdoor unit and Lossnay unit 5. The external static pressure listed in the tables includes the static pressure loss of the Dx-coil unit when using a cm straight duct between the Lossnay and Dx-coil units. When the duct work between the Lossnay and Dx-coil units is longer and/or bent, the pressure loss of the duct work should be included in the pressure loss calculation. 6. The designed airflow of the system (Lossnay, Dx-coil and duct work) at fan speed and 4 should be kept within Airflow range at and listed in the tables. This range is shown as the solid line in graphs of the characteristics curve. If the Lossnay airflow is out of this range, the compressor of the outdoor unit may stop for self-protection purposes. 7. By installing the Dx-coil unit with a Lossnay unit, the air blow noise level is quieter at fan speed 4. Please refer to the Direct Expansion coil unit for Lossnay catalogue. 8. Refrigerant leakage contributes to climate change. Refrigerant with lower global warming potential (GWP) would contribute less to global warming than a refrigerant with higher GWP, if leaked to the atmosphere. This appliance contains a refrigerant fluid with a GWP equal to 975. This means that if kg of this refrigerant fluid would be leaked to the atmosphere, the impact on global warming would be 975 s higher than kg of CO2, over a period of years. Never try to interfere with the refrigerant circuit yourself or disassemble the product yourself and always ask a professional. 226

Centralized ventilation: VL-22CZGV-E Product Merit Newly Developed Heat Exchanger During ventilation, Lossnay recovers warmth in the winter and keeps air cool in the summer. Reducing heating and cooling loads with a maximum exchange efficiency of 86%*. Normal Square Heat Exchanger Simple structure contributes to minimize pressure loss and reduce power consumption. New Diamond Heat Exchanger Due to the diamond design, air passages are longer and help realize higher exchange efficiency. Wider Length Energy Efficient The highest energy-saving performance in its class. (8.5W* minimum input power) Saves heating and cooling costs by minimizing energy loss that occurs during ventilation. Quiet At an ultra quiet 4dB*, it is the quietest product in its class. Blocks outside noise for a more comfortable environment. * Product Features Fan Speed Precise Adjustment Function Each main fan speed value can be further adjusted slightly. Use the PZ-6DR-E remote controller to adjust the speed. ) Considering the total hours of Lossnay opertaion (filter clogging), the fan power can be adjusted automatically after a given period of. 2) After the unit is installed, when if the air volume is slightly lower or higher than the desired air flow, it is possible to make a fine adjustments.
