An air conditioning unit 100 comprises a means of reducing the noise 300 of the unit 100 by preventing the dripping of condensate from a cooled heat exchanger 210, 220, and collecting or removing the formed condensate that accumulates in the unit 100. The unit 100 may cool air via natural induction and/or convection and does not require fan. The heat exchanger may comprise of a chilled beam having pipework 210 through which chilled water flows and connected to one or more spaced fins 220. An air deflection plate 230 may direct air between the fins 220. Noise reducing means 300 may comprise of a first inclined guide 310 communicating condensate via gravity to a first drain point 330. The chilled beam may be in contact with the first guide 310. The first drain point 330 comprises a gap between the first guide 310 and a first wall 322 that permits condensate to flow down by surface tension. First guide 310 may comprise of an extended portion 312 extending to a collector 320. A second guide 350 with an extended portion 352, second drain point 340 and second wall 324 may be provided and permits condensate to flow down when the volume of condensate is too great for the first drain point 330. The unit 100 is of particular use in sound recording or audio booths for conducting hearing tests.
