The air-conditioning chamber 5 comprises a plurality of sprays 23 through which water is forced by a pump 24. A valve 27 controls the supply of water from either a refrigerated source 26 or from used water in the chamber 5. Air is extracted from the enclosure 1 through a conduit 12 which has two branches 13, 14 leading respectively to chambers 10, 11 arranged at the inlet and outlet of the chamber 5. Fresh air is sumpplied through a pipe 17 having branches 18, 19 connected with the opposite ends of the conditioning apparatus. A pipe 16 leads from the outlet end of the condition apparatus to the enclosure 1, and a fan 15 is arranged in the pipe line. Heaters 6 - - 9 are disposed within the ducts 18, 13, 14, 16 respectively and dampers 20, 21, 22, 29, 28, are arranged in the ducts 17, 18, 19, 13, 14 respectively. A wet bulb thermostat 30 and dry bulb thermostat 31 are positioned in the duct 12. The thermostat 30 is adapted to control the heaters 6, 7 or valve 27 whereby the degree of humidification or dehumidification of the air passing through the heater may be regulated. The thermostat 31 controls the heaters 8, 9 and also the damper 28 whereby the amount of recirculated air by-passing the conditioner is controlled. Either of the dampers 20, 21 may also be regulated.
