A ventilatory function, is the air from outside constantly renewing the air recirculation system in the necessary proportion to achieve an adequate level of purity, since as the result of the respiratory process, oxygen is consumed and exhaled carbon dioxide, so air must always give back to the premises to avoid odors.
The filtering function is fulfilled in the battery of filters. It is to treat the air using appropriate filters to remove dust, dirt and airborne particles. The degree of filtering required depends on the type of fittings to make installation. To clean the air filters which are normally used mechanical type, consisting of porous substances in the air force to go through them, to stop dust particles carried in suspension. In the common facilities of comfort polyurethane using filters, glass wool, microfiber synthetic or metal wire mesh fabric of different steel or aluminum embedded in oil. In industrial installations or individual cases are often used special filters that are much more efficient.
A battery through a hot water or steam pipes connected with a boiler plant or electric or gas heat exchangers. For applications of comfort in cold water installations, it is often used the same The direct expansion system can also use the same battery by operating the system in heat pump cycle.
The cooling and dehumidification function is performed in summer simultaneously in the cooling coil, because if not done, the relative humidity increases considerably, causing a feeling of discomfort and heaviness. The moisture in the air circulating is removed by condensation, because the battery is operated at a temperature below the dew point.
Humidification is achieved during the heating mode through an integrated moisture exchanger element in the outdoor unit, which extracts moisture from the surrounding air without use of an external water source. After transferring moisture to the indoor unit, moist air is distributed evenly throughout the room, which also prevents air stagnation at ceiling and dryness at floor level.
The system Ururu Sarara reduces humidity without affecting the temperature by mixing dry cool air with hot air to generate a nice dry air (reheating dehumidifying). This prevents excessive cooling the environment. If the indoor temperature gets too high, the system reduces Ururu Sarara humidity also reduces the temperature (cooling dehumidifying).
