         2 . The bathroom ventilating air-conditioning system of  claim 1 , wherein the space is an under-roof space of a room other than the bathroom. 
     
     
         3 . The bathroom ventilating air-conditioning system of  claim 1 , wherein the space is an underfloor space of a room other than the bathroom. 
     
     
         4 . The bathroom ventilating air-conditioning system of  claim 3 , wherein a top panel of the main body has a power supply connector. 
     
     
         5 . The bathroom ventilating air-conditioning system of  claim 3 , wherein a top panel of the main body has a service port. 
     
     
         6 . The bathroom ventilating air-conditioning system of  claim 1 , further comprising:
 a circulating fan drawing in the air from the first air inlet and blowing out the air from the first air outlet;   a ventilating fan drawing in the air from an air inlet open to a space other than the bathroom and discharging the air outdoors for ventilation;   a compressor compressing a refrigerant;   a first heat exchanger heat-exchanging between the air sent by the circulating fan and the refrigerant;   an expansion mechanism expanding the refrigerant;   a second heat exchanger heat-exchanging the air sent by the ventilating fan and the refrigerant; and   a refrigerant circuit piped so that the refrigerant circulates in order of the compressor, the first heat exchanger, the expansion mechanism, and the second heat exchanger,   wherein the refrigerant absorbs heat from the air discharged outdoors at the second heat exchanger, and discharges heat to the air circulating in the bathroom at the first heat exchanger to heat the bathroom.   
     
     
         7 . The bathroom ventilating air-conditioning system of  claim 6 , further comprising a flow path changing valve changing a flow direction of the refrigerant in order of the compressor, the second heat exchanger, the expansion mechanism, and the first heat exchanger,
 wherein the refrigerant discharges heat to the air discharged outdoors at the second heat exchanger and absorbs heat from the air circulating in the bathroom at the first heat exchanger to cool the bathroom.   
     
     
         8 . The bathroom ventilating air-conditioning system of  claim 6 , further comprising a first damper introducing the air drawn in from the first air inlet to the second heat exchanger and passing the air through the second heat exchanger, and then introducing the air to the first heat exchanger,
 wherein the air drawn in from the first air inlet by the circulating fan with the first damper being opened is passed through the second heat exchanger, and then the air is introduced to the first heat exchanger and is passed through the first heat exchanger to reheat-dehumidify the air in the bathroom and to supply dry air to the bathroom.   
     
     
         9 . The bathroom ventilating air-conditioning system of  claim 7 , further comprising an other-room fan discharging the air to a space different from the bathroom after the air drawing in from the first air inlet has undergone heating, cooling, or reheat-dehumidifying,
 wherein the air is distributed to the bathroom and the space different from the bathroom.   
     
     
         10 . The bathroom ventilating air-conditioning system of  claim 9 , further comprising a plurality of dampers changing a path of the air drawn in from the first air inlet after the air have undergone heating, cooling, or reheat-dehumidifying. 
     
     
         11 . The bathroom ventilating air-conditioning system of  claim 10 , wherein the air is drawn in from a second air inlet open to an undressing room and a third air inlet open to a toilet. 
     
     
         12 . The bathroom ventilating air-conditioning system of  claim 11 , further comprising a second damper and a third damper changing an air path to an air path drawing in the air respectively from the second air inlet and the third air inlet to the main body. 
     
     
         13 . The bathroom ventilating air-conditioning system of  claim 9 , wherein a space different from the bathroom is one of an underfloor space and an under-roof space. 
     
     
         14 . The bathroom ventilating air-conditioning system of  claim 4 , wherein a top panel of the main body has a service port. 
     
     
         15 . The bathroom ventilating air-conditioning system of  claim 8 , further comprising an other-room fan discharging the air to a space different from the bathroom after the air drawing in from the first air inlet has undergone heating, cooling, or reheat-dehumidifying,
 wherein the air is distributed to the bathroom and the space different from the bathroom.   
     
     
         16 . A bathroom ventilating air-conditioning system comprising:
 a first air inlet open to a bathroom;   a main body conditioning air drawn in from the first air inlet; and   a first air outlet open to the bathroom,   wherein the bathroom ventilating air-conditioning system air-conditions the bathroom by circulating and sending the air between the bathroom and the main body,   wherein a top panel of the main body has a service port so that the main body can be placed in an indoor space other than on a ceiling surface of the bathroom,   wherein the first air inlet is connected to the main body through a first air inlet duct, and   wherein the main body is connected to the first air outlet through a first circulating duct.
