Packaged terminal air conditioner (PTAC) with an integrated energy recovery ventilator (ERV) or heat recovery ventilator (HRV)
View Patent ↗The present invention relates to a novel packaged terminal air conditioner (PTAC) system with an integrated energy recovery ventilator (ERV) unit or a heat recovery ventilator (HRV) unit. The integration of the ERV/HRV unit within the PTAC ensures lowering the work load of the compressor that would otherwise consume lot of power to cool/heat the room or any living space.
1 . A packaged terminal air conditioner (PTAC) system ( 200 ), comprising:
an indoor portion ( 102 );
an outdoor portion ( 104 ) embodied inside a sleeve ( 106 ), the outdoor portion ( 104 ) comprising at least
a backplate ( 202 ) with a cut-out section ( 203 ),
an outdoor fan ( 204 ) mounted on the cut-out section 203 ,
an outdoor heat exchanger ( 112 ) configured at an angle with a first end associated thereof laid proximal to a first end of an intermediate wall ( 105 ) separating an indoor portion ( 102 ) and the outdoor portion ( 104 ), and a second end associated thereof laid proximal to the backplate ( 202 );
a compressor ( 114 ) and associated refrigerant flow lines ( 114 a ), and
an ERV/HRV unit ( 300 );
wherein the angular placement of the outdoor heat exchanger ( 112 ), and the backplate-mounted outdoor fan ( 204 ) leaves a space(S) within the outdoor portion ( 104 );
wherein the compressor ( 114 ) and associated refrigerant flow lines ( 114 a ) are positioned within the space(S), wherein the space(S) further facilitates in accommodation of the ERV/HRV unit ( 300 ) within the outdoor portion ( 104 ); and
wherein the integration of the ERV/HRV unit ( 300 ) within the outdoor portion ( 104 ) ensures lowering of the workload of the compressor ( 114 ) by preheating or precooling the outdoor air entering a room by passing through a core embodied there inside to cool or heat a living space, thereby reducing the overall power consumption of the PTAC system ( 200 ).
2 . The PTAC system ( 200 ) of claim 1 further comprising a rear grill ( 108 ) with a plurality of openings ( 108 a ).
3 . The PTAC system ( 200 ) of claim 1 , wherein the outdoor fan ( 204 ) is an exhaust fan able to draw air from the outdoor portion ( 104 ) and pushes the air outside.
4 . The PTAC system ( 200 ) of claim 1 , wherein the angle may range from 20 degrees to 60 degrees.
5 . The PTAC system ( 200 ) of claim 1 , wherein the indoor portion ( 102 ) comprising a front cover ( 109 ) adapted for concealing at least an indoor heat exchanger ( 113 ), an indoor fan ( 110 ), and a heating element ( 111 ) located in the indoor portion ( 102 ).
6 . The PTAC system ( 200 ) of claim 1 , wherein the compressor 114 and associated flow lines ( 114 a ) are positioned in between the outdoor heat exchanger ( 112 ) and the intermediate wall ( 105 ).
7 . The PTAC system ( 200 ) of claim 1 , the outdoor portion ( 104 ) comprises a separation wall ( 304 ) separating the ERV/HRV unit ( 300 ) from the compressor ( 114 ) and associated flow lines ( 114 a ).
8 . The PTAC system ( 200 ) of claim 1 , wherein the ERV/HRV unit ( 300 ) is operational along with the compressor ( 114 ) in order to adjust the air conditioning requirement of the room.
9 . The PTAC system ( 200 ) of claim 1 , wherein the cut-out section ( 203 ) is circularly shaped.
10 . The PTAC system ( 200 ) of claim 1 , wherein the backplate ( 202 ) comprises an opening ( 205 ) to allow outdoor fresh air to enter within the outdoor portion ( 204 ).
11 . The PTAC system ( 200 ) of claim 10 , wherein the outdoor fresh air entering within the outdoor portion ( 204 ) through the opening ( 205 ) cools the compressor ( 114 ).
