  • the base 3 in addition to its supporting function, may contain the compressor and condensate tanks and may provide a location or connection point for a remote packaged chilled water supply. Having these items in the base 3 gives added weight to the base and more stability to the free-standing structure. In view of the weight of the base 3, to make the apparatus more mobile, it may be mounted on castors (not shown). Connection between the base 3 and upper arrangement 7 is carried out within the column 5 to which end, the column 5 may contain pipes, electrical feeds etc.

It will be appreciated that while there will usually only be one condenser and evaporator with their associated fans, more than one of these may be included as desired. As can be seen, the condenser 21 and fan 23 are housed in the upper section 9 of the upper housing 7 while the evaporator 25 and its fan 27 are located in the lower section 11. As shown, these units and their fans are of an integrated coaxial construction with the units being on the outside and surrounding the fans.

Thereafter, the cooled air is distributed downwardly from the lower central part of the lower section 11 by way of louvers or grilles 31. as can be seen, the apparatus as set up here can distribute the cooled air over 360°.
  • the upper housing 7 can be suitably insulated to avoid the formation of condensation in some environmental conditions.
  • the base 3 provides a stable base for the apparatus and also houses the refrigeration compressor together with its attendant conventional ancillaries such as suitable valves and strainers and a condensate drain reservoir. For this reason, the base may require some sound insulation.
  • Condensate tanks 33 are also located in the base and these will either be emptied manually or by means of automatic condensate pumps discharging through a suitably sized drain 35.
  • Suitably sized connection points 37 may be fitted to the base 3 for use with either a remotely sited water chiller or condensing unit.
  • Connection means for a supply of electricity are also provided Preferably an appropriately shaped cover or removable housing (not shown) is provided to cover the base and its components.
  • Figure 3 shows a view of the underside of the upper housing 7, with the small circles in the column 5 representing piping and electrical cabling connections between the upper housing 7 and the components in the base 3.
  • the grilles or louvers 25 and 31 may be reversed so as to provide cooling air from the periphery of the lower section 11 of the housing 7.
  • Any or all of the grilles or louvers may be variably controlled in respect of direction of airflow and/or size of aperture.
  • a remote control arrangement may be used for controlling any of the functions of the apparatus.
  • housing/canopy 7 Although a circular construction of the housing/canopy 7 has been shown, other shapes, such as square or polygonal could be used. Furthermore, while a pagoda shape of the housing has been shown, any suitable shape of housing could be used. If the apparatus is used internally or beneath an existing canopy, the canopy shape of the apparatus may not be needed.

  • the arrangement of figure 4 is set up to provide cooling air.
  • the upper housing 7 houses a refrigeration condenser 121 and its associated fan 123 and an evaporator 125 and its associated fan 127.

  • these units and their fans are of coaxial construction with the units being on the outside and surrounding the fans.
  • the housing/canopy in this embodiment comprises a top conical section 107 forming a "roof structure, an upper section 109 in the form of a coaxial frustoconical section and a lower coaxial frustoconical section 111 in which the maximum diameter of top section 107 is larger than the minimum diameter of the upper section 109, the maximum diameter of the upper section 109 is larger than the minimum diameter of the lower section 111 and the maximum diameter of the lower section 11 is greater than the maximum diameter of the upper section 109.
  • the housing 7 expands conically downward in three tiers.

Thereafter, the air, cooled by the evaporator 125, is distributed downwardly from the lower section 111 by way of louvers or grilles 131.
  • the switching arrangement may be operated manually by the user when he or she feels that the ambient temperature warrants it or it may be automatically controlled by means of an ambient air sensing thermostat.
  • This thermostat can suitably be manually controlled to set the changeover temperature. While a particular temperature for changeover can be set so that there can be an overlap. Thus the changeover from cool to warm may take place at one temperature, changeover from warm to cool may take place at another, different temperature, It will of course be understood that modifications may be made to this latterly described embodiment, in particular, where applicable, these modifications may be as described for the first embodiment.
