General mixing of air supply systems to supply air mixes with ambient air to the mixture of air temperature design the room and moisture. In the cooling mode, the power supply fresh air, usually around 55 F (13 C) (saturated) conditions design, making the leaves of a high speed. The high-speed flow of air turbulence makes the atmosphere causes the air to mix with the air supply. Because the whole room is almost completely mixed temperature variations are small while the concentration of contaminants is fairly uniform throughout the room. Broadcasters are normally used as air vents to create an offer broadband air. Very often vents and entrances are located on the roof. Diffusers in the ceiling are fed by the fan coils in the ceiling void or units Air conditioning in room remote machines. The fan coil unit or air handler to the return air from the air and is mixed with fresh air and cold or heat as necessary to achieve the design conditions of the room. This arrangement is known as "the distribution conventional ambient air.
Group A: on or near the ceiling, horizontal discharge
Group B: At or near the ground, non-propagation of discharge vertical
Group C: at or near the ground, the spread of vertical discharge
Group D: At or near the floor, horizontal discharge
Group E: At or near the ceiling, vertical discharge
Displacement ventilation systems of air directly to the occupied zone. The air is provided at low speed due to the induction of a minimum and mixing. This system is used for ventilation and cooling high open spaces such as auditoriums and in the courts, where energy can be saved if only the occupied zone is rather than trying to control conditions throughout the space.
The movement points are usually located at or near the ground with designed to provide air air flows freely to the ground. Where there is a heat source (such as people, lighting, computers, electrical equipment, etc.), the air rises, pulling cool air with it and move contaminants and heat from the occupied area or around the exhaust vents above. Thus, air quality in the occupied zone is generally higher than that obtained with the distribution of the mixture of ambient air. If the air mixture is recommended to ground level, this type of distribution from floor to ceiling of the ambient air is known as the distribution of air under the floor, and if the mixture is not recommended, is moving.
Hall of moving air stream has an opportunity to improve the comfort thermal and air quality (IAQ) of occupied space. He also drew the difference in density between air pollution a upper and a lower area clean. Cold air is supplied at low speed down. The convective heat creates the vertical movement of air at the top, where the input level back off the air. In most cases, these sources of heat by convection the sources of pollution (eg people, equipment or processes) that carries contaminants upward, away from occupants.
Because the air conditioning is provided directly in the space it occupies, the temperature of the air supply must be higher than mixing systems (usually above 63 F or 17 C) avoid cold drafts on the floor. By introducing air into the temperature of the air supply close to room temperature and the rate of output as a high level of thermal comfort can be ventilated by displacement.
