The specific working principle of the embodiment is as follows:
as shown in fig. 3 and 4, which are schematic diagrams of the operation of the chilled beam structure of the present invention under normal conditions, the arrow shown in the diagrams is a gas flow direction, outdoor air treated by the chilled beam air conditioning unit is called fresh air or primary air, the primary air is sent to the static pressure chamber 10 by the fan, when the primary air in the static pressure chamber is ejected at high speed through the left nozzle 13 and the right nozzle 11, according to the venturi effect, the air ejected from the nozzles causes negative pressure in the vicinity of the nozzles, so that the indoor air is forced to pass through the left box 8, the right box 3 and the inner box 6, so as to exchange heat with the heat exchanger, and the indoor gas and the primary air after heat exchange are mixed in the left air outlet channel and the right air outlet channel and are sent to the indoor. The chilled beam structure provided by the tail end of the chilled beam air conditioner can greatly increase the heat exchange area, thereby improving the heat exchange efficiency and the air intake ratio. Indoor air gets into horizontal airflow channel from two side casees about and 6 heat exchangers of inner box and becomes the overgrate air, pass through behind the short air-out passageway of distance after mixing under the venturi effect with the primary air that the nozzle sent out, become stronger lower jet stream, thereby reach the space bottom, through adjusting flexible guide plate 12, adjustable mixed air is apart from the height of bottom space behind the guide plate, make it be suitable for the space of co-altitude in the same altitude space, through adjusting flexible guide plate, adjust the speed that mixed air reachs the space bottom, thereby reduce the sense of wind, the comfort level is improved, the theory of operation picture of adjustable expansion plate is like figure 4, flexible guide plate 12 can get into the degree of depth of indoor space through flexible adjustment mixed wind, the comfort level is improved. Therefore, the chilled beam structure provided by the invention not only increases the heat exchange area, but also is suitable for a large space. Meanwhile, the tail end of the chilled beam air conditioner disclosed by the invention can be embedded in a ceiling, so that the chilled beam air conditioner is attractive and can provide a comfortable indoor environment.
As shown in FIG. 5, the chilled beam structure of the invention works in emergency, and the direction of the arrow shown in the figure is the direction of gas flow. In an emergency, an airflow horizontal channel formed by the heat exchanger and the lower surface 2 of the outer box can be blocked by the telescopic guide plate, so that indoor air is prevented from entering the heat exchanger and then being recycled back to the indoor space, meanwhile, in order to increase the air inlet volume, the normally closed air outlet 14 on the lower surface 2 of the outer box can be opened, and part of the treated fresh air enters the indoor space through the left side nozzle 13 and the right side nozzle 11 and through the left side air outlet channel 7 and the right side air outlet channel 5; and a part of the treated fresh air flows into the room after passing through the heat exchanger through the air outlet. Therefore, the invention can close the return air in time in emergency, and increase the fresh air intake by utilizing the structure of the cold beam, thereby reducing the indoor infection risk.
