Air
When it comes to air conditioning we mean not only same temperature (cold heat), but to regulate other conditions such as humidity, cleanliness (renewal and filtering) and ventilation. The cooling systems generally used mechanical compression is the realization of a cyclical process of heat transfer inside a building abroad, by evaporating refrigerants are known substances that affect the environment and the ozone layer. The rankings cooling equipment can be classified into two groups: direct and indirect expansion Expansion (cold). Direct Expansion that are characterized within the coil of the equipment, expands the refrigerant cooling air flowing in direct contact with him. Indirect Expansion They use a chiller water, which is distributed to air handling equipment where the working coil with cold water, called fan-coil.
functions to be met by air conditioning equipment are:
• Summer: cooling and humidification.
• In winter, heat and moisture.
• Common in winter and summer ventilation, filtration and circulation.
These processes should be done automatically, without disturbing noise and lower energy consumption.
Ventilation: ventilation function, is the outside air to constantly renew the recirculation air system in the proportions necessary to achieve an appropriate level of purity, as the result of the respiratory process, it consumes oxygen and exhaled carbon dioxide, so Always supply fresh air to the premises to prevent viciamientos occurring and odors.
Filtering: The filtering function is fulfilled in the battery of filters. Is to treat the air through appropriate filters to remove dust, dirt and airborne particles. The filter is the first element to be installed in air traffic because not only protects the premises put but at the same conditioning equipment.
cooling and dehumidification: The function of cooling and dehumidification, summer is done simultaneously in the cooling coil, as it is done, the relative humidity increases considerably, causing a sensation discomfort and heaviness. Moisture in the air circulating is removed by condensation, because the battery is operated at a temperature below the dew point.
Warming: air warming takes place in winter heating coil, by a steam or hot water coil cañmerías related to a boiler plant or electric or gas heat exchangers. The direct expansion system also can use the same battery by operating the system in heat pump cycle.
Wetting: In winter, if they deliver hot air without humidity, relative humidity decreases causing drying of the respiratory mucosa, with consequent physiological discomfort.
Circulation: movement function is performed by the fan is necessary because some air movement in the area of \u200b\u200bresidence in order to avoid stagnation, without causing strong currents that are harmful. Used centrifugal fans capable of circulating air flows necessary, overcoming the resistance caused friction in the system with low noise.
consumption: The cost currently represents the electrical energy is of vital importance in a specialty such as air conditioning that requires a high consumption, so its reduction is one of the basic premises criteria design. The appropriate use of insulation in the building, contributes an essential element, since they air conditioning means smaller with less power consumption over its lifetime of the building. In turn, the thermal insulation minimizes heat loss in equipment, air handling units and ductwork and plumbing installation.
is essential to adopt architectural solutions that tend to reduce energy consumption taking into account the use of solar radiation, protection and proper specification of windowed to reduce leakage.
