Air conditioning unit and air conditioning system comprising the same

Abstract

An air conditioning system is provided. Air is pulled-in/exhausted from/into an indoor space or indoor and outdoor spaces using one fan. Thus, a configuration of the air conditioning system can be further simplified.

1 . An air conditioning unit comprising:
 one fan configured to both:
 pull-in air from an indoor space and selectively exhaust a quantity of the air to an outdoor space; and 
 exhaust air into the indoor space and selectively pull-in air from the outdoor space that is also exhausted into the indoor space; and 
   one drive motor operationally coupled to the fan.   
   
   
       2 . The air conditioning unit of  claim 1 , further comprising:
 a heat-exchanger, configured to:
 receive and pass air pulled-in by the fan; and 
 selectively heat-exchange the air that passes through the heat-exchanger and is exhausted into the indoor space by operation of the fan. 
   
   
   
       3 . The air conditioning unit according to  claim 1 , further comprising a damper operationally coupled to an exhaust hole leading to an outdoor space, wherein the air pulled-in from the indoor space and the air pulled-in from the outdoor space are mixed, and a portion, determined by a position of the damper, of the mixed air is exhausted to the outdoor space via the exhaust hole, thereby performing ventilation. 
   
   
       4 . An air conditioning unit, comprising:
 a casing, comprising:
 a suction chamber, to receive air from an indoor space and an outdoor space; 
 a first exhaust chamber; and 
 a second exhaust chamber; 
   one fan, configured to:
 pull-in air from the indoor and outdoor spaces to the suction chamber; 
 transfer air from the suction chamber into the first exhaust chamber, wherein a portion of the air transferred into the first exhaust chamber is exhausted into the outdoor space; 
 transfer the portion of the air remaining within the first exhaust chamber to the second exhaust chamber; and 
 exhaust the air from the second exhaust chamber to the indoor space; and 
   one drive motor operationally coupled to the fan.   
   
   
       5 . The air conditioning unit of  claim 4 , further comprising:
 a heat-exchanger, configured to:
 receive and pass air pulled-in by the fan; and 
 selectively heat-exchange the air that passes through the heat-exchanger and is exhausted into the indoor space by the fan. 
   
   
   
       6 . The air conditioning unit according to  claim 4 , further comprising:
 an opening in the casing, the opening leading to the indoor space; and   a damper operationally coupled to the opening, wherein a position of the damper is at least one factor that determines a volume of air pulled-in from the indoor space to the suction chamber.   
   
   
       7 . The air conditioning unit according to  claim 4 , wherein the fan is disposed inside the suction chamber. 
   
   
       8 . The air conditioning unit according to  claim 4 , wherein the air pulled-in to the suction chamber from the indoor space and the air pulled-in to the suction chamber from the outdoor space are mixed with each other while being transferred into the first exhaust chamber by the fan. 
   
   
       9 . An air conditioning unit comprising:
 a casing, comprising:
 an indoor suction hole, formed as a first opening in the casing, through which air is pulled-in from an indoor space; 
 an outdoor suction hole, formed as a second opening in the casing, through which air is pulled-in from an outdoor space; 
 an outdoor exhaust hole, formed as a third opening in the casing, in which a portion of air pulled-in through the indoor and outdoor suction holes or the indoor suction hole is selectively exhausted into the outdoor space; 
 an indoor exhaust hole, formed as a fourth opening in the casing, in which the rest of the air pulled-in through the indoor and outdoor suction holes or the indoor suction hole is exhausted into the indoor space; 
   a first damper, operationally coupled to the outdoor suction hole, wherein a degree of opening of the first damper is controllable;   one fan for pulling-in air through the indoor suction hole and outdoor suction hole and exhausting air through the outdoor exhaust hole and the indoor exhaust hole; and   one drive motor operationally coupled to the fan.   
   
   
       10 . The air conditioning unit according to  claim 9 , further comprising:
 a heat-exchanger, configured to:
 receive and pass air pulled-in by the fan through the indoor and outdoor suction holes; and 
 selectively heat-exchange the air that passes through the heat-exchanger and is exhausted into the indoor space through the indoor exhaust hole by the fan. 
   
   
   
       11 . The air conditioning unit according to  claim 9 , wherein the indoor suction hole, the outdoor suction hole, the outdoor exhaust hole, and the indoor exhaust hole are sequentially disposed in an airflow direction due to the fan. 
   
   
       12 . The air conditioning unit according to  claim 9 , further comprising a second damper, operationally coupled to the outdoor exhaust hole, wherein a degree of opening of the second damper is controllable. 
   
   
       13 . The air conditioning unit according to  claim 10 , wherein the heat-exchanger is disposed between the outdoor exhaust hole and the indoor exhaust hole. 
   
   
       14 . An air conditioning system comprising:
 an air conditioning unit of any one of  claims 2 ,  5 , and  10 ; and   one or more outdoor units comprising an outdoor heat-exchanger connected to the heat-exchanger.
