<p>In the field of air conditioning modules there is a need for improved air conditioning modules which operate with greater efficiency.</p><p><Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">An air conditioning module (10; 60; 90), for location adjacent a ceiling surface, comprises a heat exchanger (16) which has an upstream side (18) to receive incoming air (20) and a downstream side (22) to discharge conditioned air (24). The air conditioning module (10; 60; 90) also includes a primary air chamber (26, 28) that is arranged in fluid communication with the downstream side (22) of the heat exchanger (16) and is spaced from the heat exchanger (16) to define a discharge chamber (42, 44) that lies between the primary air chamber (26, 28) and the heat exchanger (16). In addition the air conditioning module (10; 60; 90) includes a heat exchanger cover (70) which extends over the upstream side (18) of the heat exchanger (16) to define an inlet (72). The air conditioning module (10; 60; 90) further includes a discrete inlet barrier (78, 80; 92) that is separately formed from the heat exchanger cover (70) and is coupled between the heat exchanger cover (70) and the heat exchanger (16) to inhibit the direct passage of incoming air (20) from the inlet (72) to the discharge chamber (30, 32). The inlet barrier (78, 80; 92) includes an engagement formation (94) to mechanically secure the inlet barrier (78, 80; 92) to the heat exchanger (16).
