The warmth of your breath travels through the paper to your hands. Some 38 years ago, that simple principle led to the development of our most advanced air-conditioning technology. Poor air quality can be attributed to many problems arising in the workplace or in the home. It is believed to contribute to a Fresh air from outside Stale exhaust air Heat exchange unit (LOSSNAY core) significant loss in productivity, low morale and higher rates of sickness among many employees. The object of providing good ventilation alongside air condition in residential and commercial buildings is to provide conditions under which people can live and work comfort and safety. Fresh air supply to the room Stale room air extracted Developed and refined over the past 3 years, the LOSSNAY system has perfected the recovery of waste energy. The units reduce overall energy costs by extracting stale air and then recovering the heating or cooling energy to either warm and cool incoming fresh air. By utilising this energy, the LOSSNAY system can save up to 3% on initial capital costs of heating and cooling plant. 1

Energy-recovery calculating equation Indoor supply-air Indoor = _ Outdoor temperature (ºC) temperature (ºC) temperature (ºC) } Temp recovery Outdoor { + temperature (ºC) Calculation example : 16ºC=(2ºC _ ºC) 8%+ºC Every building needs a supply of fresh air to keep its inhabitants healthy and comfortable. Outdoor air though is rarely, if ever, the same temperature as that maintained by the building, s air conditioning system. In the summer, it is too hot. In the winter, it is too cold. This puts added stress on the air conditioner to compensate for the intake of the hot or cold air adding to the expense of operating the system. LOSSNAY all but eliminates this problem with original energy-recovery technology that uses the heat of the stale indoor air to be expelled in order to either heat or cool the incoming fresh air to a temperature much closer to the existing indoor air. This process reduces the load on the air conditioning system without cutting off the supply of vitally necessary fresh air. Stale air exhaust (dirty indoor-air) Outdoors Fresh air induction (fresh air) LOSSNAY Core Construction & Principle Fresh air exhaust (fresh heating/cooling air) SA Indoors RA Stale air induction (dirty heating/cooling air) The basic principle The remarkable technology that permits the intake of fresh air with minimal loss to indoor temperature is know as the LOSSNAY Core. The cross-flow, plate-fin structure of the energy-recovery unit along with a specially processed diaphragm keep supply and exhaust air separate, ensuring that only fresh air is introduced to the indoor environment while also allowing for the efficient transfer of heat. The improvements The microscopically small pores of the diaphragm have been made even smaller, decreasing the rate at which water soluble gases such as ammonia and hydrogen pass through. Further, a new specially processed paper used to make the diaphragm has been developed with high moisture permeability characteristics that aid in the transference of moisture for improved energy exchange. These developments further improve moisture permeability and effectiveness in shielding unwanted gases, resulting in a lower rate of gas transference and more highly efficient energy transfer. 2

In addition to the conventional Extra,, and modes, an Extra mode is added to provide a more dynamic range of air volume settings and versatility in a variety of installation environments, yielding much better energy conservation. Using a simplified timer function, it switches to Extra operation when the operation stop button is activated and it is accordingly possible to implement 24-hour energy conservation ventilation. A) Extra B) Extra Extra * The Extra and ventilation modes are selectable by the initial setting. * Extra- not equipped LGH-1RX5 and 2RX5. * The ventilation mode is actually selected in three levels, and the remote controller also displays these three levels. 3

Insulate completely. Max wiring length 1 m LOSSNAY control board CN16 Fan speed/ Ventilation mode selection Automatic ventilation setting The automatic damper mode automatically provides the correct ventilation for the conditions in the room. The following shows the effect By-pass ventilation will have under various conditions. 1. Reduces cooling load If the air outside is cooler than the air inside the building during the cooling season (such as early morning or at night), By-pass ventilation will draw in the cooler outside air and reduce the cooling load on the system. 2. Night purge By-pass ventilation can be used to release hot air from inside the building that has accumulated in buildings a business district during the hot summer season. 3. Office equipment room cooling During cold season, fresh air can be drawn in and used as is to cool rooms where the temperature has risen due to the use of office equipment. * When the outdoor air tempereture drops lower than 8ºC it changes to the heat exchange ventilation. (Display of the remote controller does not change) * In the case of By-pass ventilation, the supply air temperature slightly rises more than the outside air temperature because of the heat effect around the ducts or the unit motors. CO2 Sensor The system allows you to measure CO2 density and thereby control the amount of fresh air supplied. By connecting a CO2 sensor to the connector CN16, which is added to the LOSSNAY main unit, the setting can be switched to,, or Extra operation, which is selected when the sensor is turned ON. This system produces additional energy conservation. CO2 density Fan speed CO2Sensor CO2 density Fan speed Extra- CO2Sensor Air volume can be set using a pin position.

You can pre-set air volume according to the predictable requirement so that LOSSNAY can automatically operate at only necessary air-speed at the specified time period, which saves power consumption while maintaining the indoor air quality. Besides, once the weekly timer has been set, no switching on-off is required. timer Example A (Hourly) current RX4 series with PZ-41SLB controller 8: new RX5 series with PZ-6DR-E 8: 9: 12: 13: 17: 19: 22: low high low high low extra low Example B (Weekly) high Tolal power consumption in one day : LGH-1RX4-E : 6,6W (14 hours) LGH-1RX5-E : 5,39W (14 hours) Monday to Thursday 1,21W (18%) less 22: 8: 9: 12: 13: 17: 19: 22: low high low high low extra low Friday Saturday to Sunday 8: 9: 12: 13: 17: 22: low high low high extra low 8: 22: extra low Energy Saving by Night Purge Function During the summer season, the Night Purge function draws cooler outside air into the room to suppress temperature rises at night. This energy conservation function reduces the load when air conditioning is started the next morning. While air conditioning and ventilation are not operating, the room temperature rises as a result of heat from the skeleton and equipment. When the outside temperature becomes lower than the room temperature, ventilation starts automatically. When the room becomes sufficiently cool, ventilation is stopped. At night, the outside temperature drops. Hot air is discharged. The air conditioning load required to reach the set temperature the next morning is reduced. The out door temperture () setting can be selected either 17 C or 28 C by using Dip-Switch (SW2-7) in the LOSSNAY control box. Refer to the Instillation Manual for more information. *Do not use the night purge function if fog and heavy rain is expected. The entry of rain water may occur in the night. 6

12 28.LOSSNAY**2.qxd 11/14/8 5:11 PM Page 14 A Breath of Freshness in Restaur Restaurants A restaurant can never be too clean and its air never too fresh The atmosphere of a restaurant is crucial to securing customers and making them happy enough to come back for more. Cleanliness is the key to an attractive atmosphere and restaurants devote significant effort to ensuring the premises are sanitary. Sanitation and cleanliness, however, are not enough. No matter how clean a restaurant may look, if there are bothersome odors lingering in the air, all those efforts go to waste and the restaurant s clean image is tarnished. For these reasons, we invite restaurant owners to leave the air to LOSSNAY. LOSSNAY s superior ventilation capabilities ensure that every breath is a breath of freshness keeping guests happy. LOSSNAY also keeps owners happy with its remarkable heat recovery technology that supplies fresh outdoor air with minimal change to indoor temperature, saving on energy and expense. If it s LOSSNAY... Ventilators work to exhaust stale air and supply fresh, clean air free of the odors associated with cooking, cigarettes, and the people working and dining. Change in room temperature is kept to a minimum during ventilation thanks to the heat-recovery function. The ventilators operate very quietly so those in the midst of enjoying their meals will not be bothered by any excess noise. A large array of ventilators is available to match the layout of just about any restaurant. What would you most like to see improved in restaurants? 52.3% Improvement in overall cleanliness Others: No response Promotion of waste prevention: 5.4% Improvement in atmosphere: 6.5% Reduction of time required for food to reach the table: 12.% Improvement in employees attitude toward customer service: 2.5% 1996 Foodstuffs Consumption Monitor, Second Periodic Survey (Ministry of Agriculture, Forestry and Fisheries, Japan) 11

13 28.LOSSNAY**2.qxd 11/14/8 5:12 PM Page urants, Offices, and Schools Offices Schools Fresh air improving the overall quality of working life Many office buildings today are heavily insulated air-tight structures with little or no natural ventilation. The unnatural environment created by air conditioners without added ventilation is a breeding ground for bacteria. Factor this in with the accumulation of pollutants and odors in the form of cigarette smoke, formaldehyde, pollen, dust, and carbon dioxide, and the necessity of ventilation becomes ever more apparent. In fact, poorly ventilated buildings can give rise to Sick Building Syndrome, a malady that is known to cause headaches, sore eyes, itching, and concentration loss. This results not only in discomfort at best and sickness at worst for the building s occupants, but also the reduced productivity of the workforce. Fresh air, effectively ventilated throughout the building, is therefore essential to the overall quality of working life. If it s LOSSNAY... Creating the best possible environment for our children to succeed Children deserve all the help we can give for them to grow up healthy, happy, and prosperous. No matter how good a school s curriculum, no matter how positive and enthusiastic the teacher, a child who does not feel well will have a hard time learning. The constant flow of fresh air is nowhere as important as it is in our schools. In classrooms where large numbers of students are gathered for long periods of time, carbonic gases have the tendency to accumulate, decreasing the levels of oxygen that are vital for alertness and concentration. This is especially true during the winter months when windows tend to remain closed. LOSSNAY ventilates fresh outdoor air into classrooms to replenish the supply of oxygen and expels not only carbon dioxide, but also other pollutants and odors that inevitably sully the air. If it s LOSSNAY... Simultaneous forced-air supply and exhaust introduces fresh, outdoor air into the building, effectively ventilating even fully airtight structures. The continuous influx of fresh, outdoor air and the exhaust of stale, indoor air ensure that the indoor oxygen level is maintained at just the right balance for comfort and health. Multiple split-type units operate independently of one another, simplifying system set up and ensuring a layout that optimally matches nearly any office design. Occupants have the luxury of breathing fresh air at all times even in highly air-tight buildings. LOSSNAY operation can be interlocked with air-conditioning system operation. LOSSNAY s sound attenuation qualities prevent outside noise from penetrating into the room, helping to maintain a quiet environment for productive study. Heat that is commonly lost due to ventilation is collected and reused thanks to the LOSSNAY Core, reducing air conditioners energy load and cutting operating costs. Heat-exchange technology prevents fluctuations in temperature for significant energy savings when either heating or cooling a room.
