there is water collector 12 heat exchanger 3 bottom, and the internal surface that a side of water collector 12 was hugged closely at metal mesh plate 4 arranges the fastening, for example adopts the welding mode, also can use the internal surface of metal mesh plate 4 as the side of water collector 12, adopts the welding mode sealed to prevent leaking between the two, and the condensation water conducts partial cold volume to metal mesh plate 4 through water collector 12 side, and then forms the heat exchange through cold radiation effect and indoor air. In order to direct the condensed water to the upper filter 14 by siphoning, a siphon material 16 is entrained in the filter 14, the lower end of the siphon material 16 is immersed in the bottom of the drip tray 12 and is in full contact with the condensed water, and the other end of the siphon material 16 extends vertically to be flush with the upper portion of the filter 14. When the return air with higher indoor temperature passes through the siphon material 16 and the filter 14, the condensation water and the return air have the evaporation cooling effect, so that the cold energy of the condensation water is fully utilized, and the condensation water is recycled. Because the fresh air with low drying temperature is responsible for the indoor wet load, condensed water in the chilled beam is not continuously generated but intermittently exists, so that the amount of the condensed water cannot be absorbed by the dry and cold fresh air too much. For the sake of safety, a condensed water outlet 11 is arranged, and the condensed water outlet 11 is higher than the bottom of the water receiving tray 12 by a certain distance, so that the overflow drainage function can be ensured. The siphon material 16 is cotton fiber, and the soft characteristic of the cotton fiber towel can be conveniently woven into the filter screen due to the water absorption effect of the cotton fiber towel.

A plurality of downward conical nozzles 5 are led out from a partition plate 7 at the lower part of the static pressure box 2 and are arranged in parallel with the heat exchanger 3, and the centers of all the nozzles 5 are on the same straight line and have the same distance with the wall hanging plate 8; the height of each nozzle 5 and the diameter of the nozzle 5 may be different as necessary. In order to prevent the outer surface of the nozzle 5 from generating condensed water, the outer surface of the nozzle is pasted with a wetting material, the wetting material is connected with the flow guide pipe 13, and the other end of the flow guide pipe 13 is fixedly connected to the water pan 12, so that the condensed water generated on the outer surface of the nozzle 5 smoothly flows onto the water pan 12 for recycling. The infiltrating material can be cotton fiber, or some porous foam sponges, or adhesive tapes with flocked surfaces and the like, and the infiltrating material can absorb and transfer water drops to other places (mainly depending on the action of gravity or evaporation) so as to avoid condensed water from gathering and accumulating to form water drops, and the water drops are easy to fall, do not conform to sanitary conditions and are easy to complain by users.
Referring to fig. 1, the working principle of the present embodiment is as follows: the primary air enters the static pressure box 2 through the air pipe connector 6, flows from the inlet C of the nozzle 5 to the position B of the nozzle 5 and is ejected at high speed, and a negative pressure area D is generated around the outer surface of the rear end of the conical nozzle 5 under the Venturi effect. The indoor return air (secondary air) is sucked into the negative pressure region D from the return air inlet E through the filter 14 and the heat exchanger 3 at atmospheric pressure, and the indoor return air is heat-exchanged (cooled or heated or heat-exchanged is not generated) at the heat exchanger 3. The primary air and the secondary air are mixed and then are guided to the indoor by the air deflector 10 from the air outlet A.
