A ground replacement air supply device

Abstract

The invention discloses a floor-type displacement air supply device comprising a drum-type windproof cloth curtain which can be manually pushed and pulled, wherein the outer side of the drum-type windproof cloth curtain is provided with a primary air supply outlet and a secondary air supply outlet, and the middle of the primary air supply outlet and the secondary air supply outlet is a ventilating current-sharing tapered cloth bag; a water knockout trap is arranged between the secondary air supply outlet and the tapered cloth bag; the outer surface of the water knockout trap is covered with a prefabricated integral thermal insulation shell; the top of the tapered cloth bag is fixed on the center of the top of the whole device, and the lower end of the tapered cloth bag is connected with an interface device; an air quantity valve for regulating and fixing is arranged in the interface device; and the upper angle of the air supply device is provided with a loudspeaker or an evacuation indicating device (instrument). The invention has the advantages that the air speed and direction of supplying air are easy to control, and the air distribution is even and can be regulated according to seasonal demands; in terms of the thermal insulation of the water knockout trap, the requirements of thermal isolation and no dew formation can be realized easily; and the pipeline construction and installation can be carried out conveniently. The integrated loudspeaker and the evacuation indicating device (instrument) can conveniently play roles in communicating, guiding and indicating indoor personnel.

Description

technical field [0001] The invention relates to the technical field of ventilation and air conditioning, in particular to a floor replacement air supply device. Background technique [0002] At present, in the traditional form of replacement air supply outlet in the field of ventilation and air conditioning, the wind speed and air supply direction of the air outlet are generally not adjustable, and the uniformity of the air supply air flow is usually adjusted by a fixed metal grid plate device; the structure of the air supply outlet is simple and functional. Single, only used for air supply requirements in summer. However, in practical applications, the air supply parameters are often different in different seasons (mainly winter and summer). If the air supply cannot be adjusted, it is difficult to achieve the expected effect of replacing the air supply; at the same time, due to the single form and function Some devices such as water collectors, indoor loudspeakers and evac...

[0002] At present, in the traditional form of replacement air supply outlet in the field of ventilation and air conditioning, the wind speed and air supply direction of the air outlet are generally not adjustable, and the uniformity of the air supply air flow is usually adjusted by a fixed metal grid plate device; the structure of the air supply outlet is simple and functional. Single, only for summer air supply requirements

However, in practical applications, the air supply parameters are often different in different seasons (mainly winter and summer). If the air supply cannot be adjusted, it is difficult to achieve the expected effect of replacing the air supply; at the same time, due to the single form and function Some devices such as water collectors, indoor loudspeakers and evacuation displays with floor radiation design have to be set up and installed independently, which not only affects the beauty of the room but also increases the investment cost.
