Abstract

Disclosed herein is an apparatus, in the form of a package air conditioning unit (PAC) for conditioning air in a space. The space may comprise the interior space(s) of buildings such as hospitals, enclosed shopping malls, warehouses, factories, etc. The PAC comprises a first arrangement, in the form of a suction chamber for receiving an air stream from the space (e.g. return air) and discharging an air stream to the space (e.g. supply air). The PAC has a second arrangement, in the form of second chamber for receiving an air stream from outside the space (e.g. fresh air) and discharging an air stream to outside the space (e.g. exhaust air). The second chamber is configured to receive a portion of the return air via the suction chamber.

exact text as granted — not AI-modified
1 . An apparatus for conditioning air in a space comprising:
 a first arrangement for receiving an air stream from the space, and discharging an air stream to the space; and   a second arrangement for receiving an air stream from outside the space and discharging an air stream to outside the space;   the second arrangement being configured to receive a first portion of the air stream received from the space via the first arrangement.   
     
     
         2 . An apparatus in accordance with  claim 1 , wherein the first portion of the air stream received from the space is combined in the second arrangement with the air stream received from outside the space to form a first combined air stream. 
     
     
         3 . An apparatus in accordance with  claim 2 , wherein the first combined air stream is discharged outside the space. 
     
     
         4 . An apparatus in accordance with any one of the preceding claims, wherein the second arrangement is able to be isolated to the receipt of air from the first arrangement. 
     
     
         5 . An apparatus in accordance with any one of the preceding claims, wherein the first arrangement receives another air stream from outside the space. 
     
     
         6 . An apparatus in accordance with  claim 5 , wherein the other air stream is combined with a second portion of the air stream received from the space to form a second combined air stream that is discharged to the space. 
     
     
         7 . An apparatus in accordance with any one of the preceding claims, wherein the first arrangement comprises a first heat exchanger. 
     
     
         8 . An apparatus in accordance with any one of the preceding claims, wherein the second arrangement comprises a second heat exchanger. 
     
     
         9 . An apparatus in accordance with  claim 8 , wherein the first and second heat exchangers are fluidly connected. 
     
     
         10 . An apparatus in accordance with  claim 9 , wherein:
 in a first mode of operation, when the temperature of the first portion of the air stream is greater than the temperature of the air stream received from outside the space; and when the streams are combined in the second arrangement, the first portion heats the stream received from outside;   in a second mode of operation, when the temperature of the first portion of the air stream is less than the temperature of the air stream received from outside the space; and when the streams are combined in the second arrangement, the first portion cools the stream received from outside.   
     
     
         11 . An apparatus in accordance with  claim 10 , wherein:
 in the first mode of operation, the second heat exchanger extracts heat from the first portion of the air stream and the first heat exchanger emits the extracted heat;   in the second mode of operation, the second heat exchanger extracts coolth from the first portion of the air stream and the first heat exchanger emits the extracted coolth.   
     
     
         12 . An apparatus in accordance with  claim 11 , wherein:
 in the first mode of operation, the heat emitted heats the combined stream discharged to the space.   in the second mode of operation, the coolth emitted cools the combined stream discharged to the space.   
     
     
         13 . An apparatus in accordance with any one of the preceding claims, wherein the air stream received from the space includes spill air and return air. 
     
     
         14 . An apparatus in accordance with any one of  claims 6  to  13 , wherein the first arrangement further comprises at least one fan configured to discharge the second combined air stream to the space. 
     
     
         15 . An apparatus in accordance with  claims 3  to  14 , wherein the second arrangement further comprises at least one fan that is able to discharge the first combined air stream to outside the space. 
     
     
         16 . An apparatus in accordance with any one of the preceding claims, wherein the first or second arrangement further comprises at least one other fan which is able to cause the second arrangement to receive the first portion of the air stream received from the space. 
     
     
         17 . An apparatus in accordance with any one of the preceding claims, wherein the second arrangement further comprises an assembly to hold a fluid. 
     
     
         18 . An apparatus in accordance with  claim 17 , wherein the second arrangement further comprises a discharging assembly arranged to discharge the fluid. 
     
     
         19 . An apparatus in accordance with  claim 18 , wherein the discharging assembly and the fluid holding assembly are fluidly connected. 
     
     
         20 . An apparatus in accordance with  claim 18  or  19 , wherein the fluid discharged by the discharging assembly mixes with the air stream received from outside the space in the second arrangement. 
     
     
         21 . An apparatus in accordance with  claim 20 , wherein the said mixing of the fluid and the outside air stream evaporatively cools the air stream in the second arrangement.
