Air Central Conditioner Unit

The air filter 110 for the conditioning chamber how to say it at work 72 can be removed from re-conditioning other name for the holy spirit unit 50 by first disconnecting the lamp 56 below the slot 180 in the upper panel portion 170 of the reflector 168, and pulling the filter 110 at its lower end slightly projecting downwardly from the slot 180 so that the filter 110 is disengaged from the clip member 112 and downwardly slides between the slip guides 114 and 116 within the conditioning chamber 72 and further between the guide portions 182 and 182' of the support structure 154.

The air-flow deflector blades 186 and 186' are used to downwardly direct the streams of air blowing into the space to be air conditioned from the longitudinal spaces 184 and 184' in the illuminating appliance 52 especially when the re-conditioning unit 50 is operated as a space heater for enabling the hot air to uniformly circulate in the space to be air conditioned.

Designated by 186 and 186' are air-flow deflector blades which are mounted on the inner faces of the front and rear vertical wall portions 158 and 158', respectively, of the support structure 154 and which are rotatable about pivotal shafts parallel with the wall portions 158 and 158'.

This problem becomes particularly serious if the room 24 is divided into separate sections by the partition member 24 so that one of the sections is void of the air inlet opening 26 and/or the air outlet opening 28 in the ceiling panel 20, as in the case of the uppermost room in the shown building 10.
The re-conditioning unit 50 and the illuminating appliance 52 can be installed all from below the opening in the ceiling panel and, furthermore, the maintenance and servicing of the re-conditioning unit 50, especially the air filters 110 and 122 can be made all from below the illuminating appliance 52.
The lamps 56 and 56' thus mounted on the support structure 154 extend horizontally in parallel between the front and rear vertical panel portions 172 and 172' of the reflector 168. From the heat exchanger 122 in the heat-transfer chamber 74, the refrigerant gas is returned to the compressor 76 for repeating the cycle. The elongated opening 174 is so sized and located in the panel portion 170 as to be substantially coextensively under the elongated opening 102 in the lower wall portion 88 of the conditioning chamber 72 of the re-conditioning unit 50, as will be best seen in FIG.

A refrigerant is thus passed through the heat exchanger 104 toward or from the compressor 76 on the cooling or heating cycle of the re-conditioning unit 50. The re-conditioning unit 50 has its lower end not exposed to the room below the ceiling panel and is invisible from below the illuminating appliance 50, providing an excellent external appearance of the ceiling when viewed from below the ceiling panel. A combination as set forth in claim 22, in which said horizontal wall portion comprises a pair of spaced parallel guide portions extending generally upwardly from said elongated slot for slidably receiving therebetween a portion of said filter. As previously mentioned, however, the locations most desirable for car golf rear seat the installation of the re-conditioning units 50 over the ceiling panels 20 are sometimes coincident with those which are most desirable for the installation of ceiling-mounted illuminating appliances 52 on the panels. An example of such an arrangement is illustrated in FIGS. SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a combination of a local re-conditioning unit for use with a central air conditioning system adapted to use a ceiling chamber of a building as part of the ductwork for the return air of royal princess hotel chiang mai the central conditioning system and an illuminating appliance for installation in the ceiling chamber through an opening formed in the ceiling panel forming the ceiling chamber.
A meshed or perforated sheeting 176 such as a wire mesh is detachably mounted on the lower face of the upper panel portion 170 and covers the opening 174 in the panel portion.
7 is a partially taken-away perspective view showing the illuminating appliance forming part of the embodiment illustrated in FIGS. 6, the outer casing 64 is open at the front end of the heat-transfer chamber 74 and has a rear wall portion 118 defining the rear end of the heat-transfer chamber 74.
An elongated clip member 138 is fixedly positioned between the upper edges 132 and 132' and extends throughout the length of the edges which are assumed to extend substantially between the vertical ends of radio shack product manual the open kansas knight of columbus front end of the heat-transfer chamber 74 as will be seen from FIG.
The ceiling chambers 18 are in communication with a return duct 46 through openings 48 formed in the vertical wall 12 of the load-carrying frame structure. The heat pump is thus operative, either on the cooling cycle or on the heating cycle, to exchange heat between the air being circulated through the heat-transfer chamber 74 in the ceiling chamber 18 and the air which is passed through the conditioning chamber 72 from and back into the space to be air conditioned.
The support structure 154 comprises a horizontal upper wall portion 156 and a pair of spaced, parallel, vertical wall portions 158 and 158' projecting cayman island business directory downwardly from the front and rear longitudinal ends of the wall portion 156. When the filter 110 is moved into the initial position thereof, the lamps 56 are fitted to the support structure 154. The vertical position casino frontier hotel new of the reflector 168 relative to the support structure 154 is adjusted by the fastening means.
The casing means is further formed with an air inlet opening located at the bottom of the conditioning chamber and at least one air outlet opening located at the bottom of the casing means. 6 is a cross sectional view taken along lines VIVI of FIG. The air in the return duct 46 may be in part recirculated into the mixing chamber in the radisson hotel san antonio conditioning unit 30 by airline british international midland means of a recirculation air damper (not shown) positioned windward of the air discharge fan 42 especially on the heating cycle of the conditioning unit for re-use of the heat in the recirculated air. The anchor nuts 60 are first driven into the slab of the floor or roof structure 14 or 16 above the elongated opening 54 in the ceiling panel 20. When, therefore, the local re-conditioning unit 50 is in operation on the cooling or heating cycle thereof, air in the space below the ceiling panel 20 is caused to enter the windward side of the air filter 110 and the heat exchanger 104 through the meshed or perforated sheeting 176 as indicated by an arrow a in FIG.
A analog cmos design optimizing combination as set forth in claim 16, in which said slot extends substantially throughout length of said horizontal panel portion. A combination as set forth in claim 26, in which said illuminating appliance comprises an elongated slot aligned with said slot in said lower wall portion of said casing means for vertically passing therethrough a further lower portion of said air filter. A combination as set forth in claim 1, in which said re-conditioning means further comprise a collecting vessel positioned within said conditioning chamber for collecting therein the water condensate produced in the conditioning chamber, a vaporizing vessel positioned within said heat-transfer chamber and communicating with said collecting vessel for storing the water condensate conducted from the collecting vessel into the vaporizing vessel and allowing the water condensate to be vaporized from the vaporizing vessel. While the central air conditioning system incorporating the improvement according to the present invention may be useful for the comfort cooling and heating of residential buildings and premises or for district air conditioning purposes, the same will prove advantageous particularly when installed in relatively large-sized, multiroom latest motorola camera phone and/or multistory structures such as business, commercial, industrial, institutional or public buildings as will be understood as the description proceeds.
