3 LOSSNAYSYSTEM ssnay ventilation systems are renowned industry-wide for their. They offer environment-friendly energy recovery and humidity control, and enable air conditioning systems to simultaneously provide optimum room comfort and energy savings. One Adult Needs 4 Litres (Equivalent to Two Barrels) of Fresh Air Every Hour In everyday life, occasionally there are times you might feel out of breath, for example, when you re in a closed room or a crowded train. This is because the air becomes carbon-rich; that is, the carbon dioxide (CO) that people exhale accumulates in closed spaces, thereby increasing the carbon gas density. The average person exhales about litres of carbon-rich gas per hour. If there is no ventilation, the carbon gas density increases in the room as the oxygen density decreases, and various problems could occur. To live comfortably, every person needs a surprising 4 litres of fresh air per hour; a volume equivalent to two large barrels. Main Gaseous Contaminants Found Indoors Contaminant Name Carbon Monoxide Sulfurous Gases (sulfur oxide) Nitrous Gases Nitric oxide Nitrogen dioxide Carbon Dioxide Gas Bad Odours Chemical Formula CO SO NO NO CO Harm Causes severe damage to the body Damages the body; causes asthma; reacts with metals, generates rusting Direct harm to the body is unclear; becomes NO when bound with oxygen, causes indirect harm; irritates the throat and lungs, possibly causing serious damage. No direct harm unless the gas is very dense Bad odours found inside residences do not cause serious damage health-wise, but may create discomfort Source: An Introduction to Home Environment Studies. S. Fuji, Shoukokusha Publications Oxygen density and deficiency disorders Normal air density 1% Safety limit (ppm) Increase in breath and pulse rate, headaches, queasiness, nausea Dizziness, nausea, muscular weakness (Potentially fatal) Facial pallor, unconsciousness, vomiting Coma (Death within 8 minutes) Respiratory arrest, convulsions, death 6% 1% 8% 1% Oxygen density 18% 16% Ventilation and Change in Amount of CO Exhaled Before 1 smoking Window closed Window open After smoking Smoking time (min) Ventilation Supporting Both Heating and Cooling When using a ventilating system, indoor air that has been heated or cooled escapes causing the room to become cold in winter or hot in summer. As the heated/cooled air dissipates, the environment becomes uncomfortable, precious energy and money are wasted, and the increasing amount of contaminated indoor air that needs to be ventilated turns into a major problem. The reason for this phenomenon is that heating/cooling and ventilation have an incompatible relationship that is inversely proportional. For air conditioning, Mitsubishi Electric proposes heating and cooling systems that provide effective ventilation at the same time. Energy escapes during ventilation More energy used to maintain room temperature Heating/cooling results Inverse relationship Ventilation becomes necessary Facility maintenance costs increase Ventilation volume Contamination occurs Ventilation is sacrificed 141

4 Simple Construction, Performance That s ssnay Air Ventilation Simple Construction As shown in the illustration, the ssnay element design adopts a cross-flow shape and plate-fin construction that enables total heat exchange using specially processed paper dividers and interval plates. Since the dividers separate the intake and exhaust passages, fresh air is always inducted without mixing with exhaust air. Indoor-air supply (fresh heating/cooling air) Divider (specially processed paper) Indoor Outdoor Outdoor air outlet (dirty indoor-air expelled) Outdoor-air intake (fresh air) Operating Principle The ssnay element skillfully provides total heat exchange temperature (i.e., sensible heat) and humidity (latent heat) using specially processed paper dividers and moisture permeability characteristics; enabling dirty indoor-air to be expelled outside and fresh outdoor-air to be inducted inside, passing through the ssnay without ever mixing. The principle can be explained by a simple experiment. Roll a sheet of paper into a tube shape and blow through it. The warmth of the air is transferred to your hand, and conversely, if cold air is blown through the tube, the coldness would be transferred to your hand. The same special properties of the paper are used for the ssnay total heat exchanger. What are Sensible Heat and Latent Heat? Sensible heat is the heat resulting from temperature changes (i.e., rise/fall) in a substance, and latent heat is that which is generated or dissipates according to changes in the state of a substance (e.g., evaporation, condensation, etc.). Temperature (sensible heat) exchange Thermal conduction and heat transfer through the divider in all temperature ranges. Humidity (latent heat) exchange Water vapor transference through the divider in all temperatures ranges based on differences in water vapor pressure. Indoor-air intake (dirty heating/cooling air) Interval plate (specially processed paper) Comfortable Air Ventilation Regardless of Being Hot or Cold In summer Temperature difference between air supply and room: 1.7 C In winter About 4kg/h of water vapor is recovered.

Exhaust air If air is not supplied, the air pressure in the room drops and the entire space is not properly ventilated. If ssnay is used Supply air Exhaust air By inducting and expelling air concurrently, ssnay constantly provides sufficient ventilation and maintains a good air environment indoors. 14

5 Mr. Slim & ssnay Interconnected Ventilation Systems -quality Air Conditioning Systems Fusing Comfort and Economy Mr. Slim Outdoor Unit Mr. Slim Indoor Unit Mr. Slim A-control Remote Controller ssnay Six Major Merits of Interconnected Ventilation Systems Problems Indoor-air is contaminated by odour, dust, etc. Air induction is insufficient, resulting in insufficient ventilation. Heating/Cooling airflow doesn t reach foot level Conditioned air expelled outside with exhaust air running cost Separate switches for air conditioner and ventilation systems makes operation troublesome Detailed zone-by-zone operation not possible Air conditioner and ventilation fan operation noise annoying Outside traffic noise annoying Maintenance such as changing the filter is difficult Merits Efficient, fresh-air ventilation Comfortable airflow Energy-saving ventilation Control with a single remote controller Quiet operation 1-year no-maintenance filter CO Sensor The system allows you to measure CO density and thereby control the amount of fresh air supplied. By connecting a CO 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. CO density Fan speed COSensor CO density Fan speed Extra- COSensor Air volume can be set using a pin position. To force fan speed externally CO sensor, etc. (When CO increases: Closed) SW1 SW1: fan speed operation switch (When closed: For fan speed operation) Remote display adaptor (Optional) PAC-88HA-E Brown 1 Red Orange 3 Yellow 4 Green Not used. Insulate completely. Max wiring 1 m LOSSNAY control board CN16 Fan speed/ Ventilation mode selection When SW1 is ON, fan speed of the LOSSNAY will be set to (Extra-) regardless of the remote control setting. Use this in such a way that it ventilates at or Extra- fan speed normally, and when the external sensor detects contamination of indoor air, it changes to (Extra ) fan speed operation. One Remote Controller for All Operations Control both Mr. Slim and ssnay units with a single controller, the new MA Remote Controller. Compared to conventional air conditioning and ventilation systems that require a separate remote controller for each unit, operation is greatly simplified. A variety of features are incorporated, such as a Ventilation Changeover Switch for independent operation of the ssnay when running for long periods of time.
