The air conditioner disclosed in each of the patents uses outdoor air as a source of heat or as a medium to be heated by the rejected heat and basically differs in principle of operation from the local air re-conditioning unit combined with the central air conditioning system in that the re-conditioning unit is operative to exchange heat with the air which has once been heated or cooled by the central air conditioning system and which has been circulated through the space or spaces to be air conditioned.
BRIEF DESCRIPTION OF THE DRAWINGS The features and advantages of the combination re-conditioning unit and illuminating appliance according to the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings, in which like reference numerals designate corresponding structures, units, pars and spaces and in which: FIG. . , between the inner faces of the partition nafta free tradeprotein degradation members 66 and 68. The heat-transfer chamber 74 has further accommodated therein an axial-flow fan 124 which is driven by a motor 126 for rotation about a horizontal axis substantially normal bower kid museumbowflex revolution to the heat exchanger 122 and which is located in proximity to the above-mentioned opening 120 in the rear wall portion 118 of the casing 64.
1, a central air conditioning system is shown installed on a multistory, multiroom building 10. The upper wall portion 128 has formed along its front end a pair of spaced parallel edges 132 and 132' which project downwardly from the inner face of the wall portion 128.

The spaces 184 and 184' thus extend substantially throughout the lengths of the support structure 154 and the reflector 168 and have open lower ends.
The distribution ductwork comprises a main supply duct 44 leading from the discharge side of the air supply fan 40 and a plurality of branch ducts 44' leading from the main supply duct 44. 10 to 12, the elongated slots 160 and 160' is formed only in a longitudinally intermediate portion of the upper wall portion 156 of the support structure 154 of the illuminating appliance 52 and, in addition, the upper panel portion 170 of the reflector 168 is formed with first and second openings 174a and 174b in its lateral end portions, viz.

From the heat exchanger 104, the refrigerant gas is returned to the compressor 76 so as to repeat the cycle. The present invention contemplates elumination of the above described problems encountered in the prior art air re-conditioning units which are used supplementarily to the central air conditioning system of, typically, the single-duct design. The upper wall portion 86 of the inner casing 84 is formed with openings 100 and 100' which are spaced apart from each other in parallel with the front and rear ends of the wall portion 86 and which are preferably located closer to the rear end of the wall portion 86 as shown in FIGS. This may be accomplished by provision of two partition members (not shown) in each of the longitudinal spaces 184 and 184' for isolating such portions of the spaces 184 and 184' from the longitudinally intermediate portions of the spaces or by closing the lower ends of the intermediate portions of the spaces dave chappelle block party 184 and 184'.
The draught of air in the upper space 94 is divided into two streams as indicated by the arrow b and b' toward the upper ends of the vertical spaces 96 and 98 on both sides of the inner casing 84. Furthermore, the space below the upper panel portion 170 of the reflector 168 of the illuminating appliance 52 is in communication with the windward side of the air filter 110 and the heat exchanger 104 avon key ring skeleton within the inner casing 84 in the conditioning chamber 72 of the re-conditioning unit 50 through the meshes or pores in the meshed or perforated sheeting 176.
The slot 180 in the upper panel portion 170 of the reflector 168 is thus invisible from above the illuminating appliance 52 with the lamp 56 located immediately below the slot 180.

When the building is completed and transferred to the client or to tenants of the client from the contractor, it is usual that the users of the building have the floors or the existing compartments of each of the floors partitioned into sections and subsections depending upon the purposes for which the floor spaces are to be utilized.

The compressor 76, heat exchangers 104 and 122, shift valve and expansion valve make up a closed loop for circulating nike factory in memphis the broken bow real estate refrigerant therethrough and constitutes an air-to-air refrigerant-flow reversible heat pump. During heating cycle of the heat pump, the refrigerant compressor 76 delivers the hot refrigerant gas to the heat exchanger 104 in the conditioning chamber 72, in which the refrigerant gas is condensed into a liquid state and liberates the latent heat of condensation into the air passed through the heat exchanger 104 serving as a condenser. When the re-conditioning unit 50 is operated on the heating cycle, the heat exchanger 104 is connected at the incoming end of the coil to the delivery side of the compressor 76 through the shift valve in the other position and thus functions as a refrigerant condenser as is well known in the art of heat pumps. The used air thus entering the ceiling chambers 18 in the individual floors is passed through the openings 48 in the vertical wall 12 into the return duct 46 and is discharged into the open air through the air discharge duct 34 by means of the discharge fan 42. The filter 140 has a vertically intermediate portion elastically received between slip guides 142 and 142' which may be secured to the side wall portions defining the lateral ends of the open front end of the heat-transfer chamber 74, one of such side wall portions being constituted by the previously mentioned partition member 66 between the conditioning and heat-transfer chambers 72 and 74 (FIG. BACKGROUND OF THE INVENTION The present invention relates in general to air conditioning systems and particularly to a central air conditioning system arranged with local re-conditioning units. As previously noted, however, the latent and sensible load vary from one of the rooms 22 to be conditioned to another due to, for example, the placement of heat-emanating or heat-absorbing equipment and appliances, illumination for the rooms and the gains or losses of heat as caused by solar and sky radiation.

4 to 6, each of the local re-conditioning units 50 comprises a casing 64 which is internally divided by vertical partition members 66 and 68 into three separate chambers consisting of a refrigeration compressor chamber 70, a conditioning chamber 72 and a heat-transfer chamber 74.
