     BACKGROUND OF THE PRESENT DISCLOSURE 
     Field of the Present Disclosure 
     The present disclosure relates to an air-conditioning device for an electric mobility and an air-conditioning system for an electric mobility, using the same, wherein a heat pump is used to provide high-temperature air to an evaporator, removing condensed water generated in the evaporator after cooling, and sterilizing the evaporator. 
     Description of Related Art 
     Recently, an electric vehicle has appeared as a social issue for implementing eco-friendly technologies and solving problems such as energy shortage. The electric vehicle operates by use of a motor which receives electricity from a battery and outputs power. Therefore, the electric vehicle is in the limelight as an eco-friendly vehicle in that carbon dioxide is not discharged, noise is very low, and the energy efficiency of a motor is higher than the energy efficiency of an engine. 
     The essential technology for realizing the electric vehicle is a technology regarding a battery module, and recently, active research has been conducted on battery weight reduction, battery miniaturization, battery charging time reduction, etc. A. A battery module should be used in an optimal temperature environment in order to maintain an optimum performance and a long lifespan. 
     Furthermore, the electric vehicle does not generate waste heat, which is generated during combustion in a separate engine like an internal-combustion engine, and thus performs heating in the vehicle by an electric heating device in winter. Furthermore, warm-up is needed to improve battery charging/discharging performance in cold weather, and thus a separate coolant-heating type electric heater is provided and used. That is, in order to maintain the optimal temperature environment for the battery module, the electric vehicle utilizes a technology of operating a cooling/heating system for adjusting the temperature of the battery module, independently of a cooling/heating system for air conditioning in the vehicle. 
     The electric vehicle utilizes an air-conditioning device to perform cooling in the vehicle in summer. That is, cooled air is generated by the circulation of a refrigerant and provided into the vehicle. 
     However, at the time of generating cooled air, an evaporator is operated, and thus condensed water is generated in the evaporator. The condensed water may contaminate the evaporator, causing odor. In order to solve the present problem, even when driving of the electric vehicle is stopped, a blower may be operated to remove the condensed water in the evaporator. However, the condensed water generated in the evaporator may not be completely removed. 
     The information included in this Background of the present disclosure section is only for enhancement of understanding of the general background of the present disclosure and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

FIG.  12    illustrates condense water removal and sterilization by a dehumidifier of the air-conditioning system for an electric mobility, illustrated in  FIG.  10   . 
     As illustrated in  FIG.  1   ,  FIG.  2   ,  FIG.  3   , and  FIG.  4   , an air-conditioning apparatus for an electric mobility, according to an exemplary embodiment of the present disclosure, may include: a housing  100  which includes a main blower  200  and in which air flows when the main blower  200  operates; an internal condenser  300  configured to heat air in the housing  100  and an evaporator  400  configured to cool air in the housing  100 ; an external condenser  500  provided in a direction in which the internal condenser  300  and the evaporator  400  are provided; an auxiliary blower  600  provided so that air flows outside through the internal condenser  300 , the evaporator  400 , and the external condenser  500 ; a flow channel control door  700  configured to selectively regulate the air flow caused by the main blower  200  or the auxiliary blower  600 ; and a controller  800  configured to receive an input regarding cooling/heating or whether to sterilize the evaporator  400 , and control the flow channel control door  700  so that air flows inside by operation of the main blower  200  while the air is cooled/heated, and such that, while condensed water of the evaporator is removed and the evaporator is sterilized, air is heated through the internal condenser  300  by operation of the auxiliary blower  600  and then provided to the evaporator  400 . 
     Thus, according to an exemplary embodiment of the present disclosure, air flowing in the housing  100  may be heated by passing through the internal condenser  300  to form heating air, and may be cooled by passing through the evaporator  400  to form cooling air. In order to improve heating performance, a separate PTC heater, in addition to the internal condenser  300 , may be further provided. 
     The internal condenser  300 , the external condenser  500 , and the evaporator  400  may be configured to ensure cooling/heating efficiency through a heat pump which exchanges heat with another cooling medium during the circulation of a refrigerant. 
     In the present disclosure, in order to sterilize the evaporator  400  after cooling air-conditioning air, the auxiliary blower  600  and the flow channel control door  700  may be provided in the housing  100 . Each of elements including the main blower  200 , the auxiliary blower  600 , and the flow channel control door  700  may be controlled by the controller  800 . 
     In an exemplary embodiment of the present invention, an actuator such as a step motor is mounted to the flow channel control door  700  and electrically connected to the controller  800 . 
     In the housing  100 , air may flow when the main blower  200  or the auxiliary blower  600  operates. 
     When the main blower  200  operates, outside air or inside air may be introduced into the housing  100 , and the outside air or the inside air, the temperature of which has been adjusted through the evaporator  400  or the internal condenser  300 , may be provided as air-conditioning air into the mobility. At the instant time, the flow channel control door  700  may be positioned to allow the flow of air introduced by the main blower  200  and to block the flow of air toward the auxiliary blower  600 . Furthermore, when providing the internal air-conditioning air, the evaporator  400  and the internal condenser  300  may be activated so that the temperature of air flowing to the mobility is adjusted based on the temperature needed in mobility. Air may selectively flow to the evaporator  400  and the internal condenser  300  by a temperature adjustment door  910 . 
     When the auxiliary blower  600  operates, inside air may be introduced into the housing  100 , and the air may be heated through the internal condenser  300  and provided to the evaporator  400 . At the instant time, the flow channel control door  700  may be positioned to block the flow of air introduced by the main blower  200  and allow the flow of air toward the external condenser  500 . Furthermore, when a request for the sterilization of the evaporator  400  is made, the air heated through the internal condenser  300  may be supplied to the evaporator  400  while the evaporator  400  is deactivated. Thus, the high-temperature air heated through the internal condenser  300  may dry condensed water generated in the evaporator  400 , and may sterilize the evaporator  400  at a high temperature. 
     As illustrated in  FIG.  2   , the housing  100  may include a first housing  110  in which the main blower  200  is provided to make outside air or inside air flow, and a second housing  120  which fluidically-communicates with the first housing  110  and in which the internal condenser  300 , the evaporator  400 , the external condenser  500 , and the auxiliary blower  600  are provided. 
     That is, the housing  100  may include the first housing  110  and the second housing  120 , wherein the first housing  110  may include an inside/outside air door, a filter, etc., which are not shown, in addition the main blower  200 , and the second housing  120  may include the internal condenser  300 , the evaporator  400 , the external condenser  500 , and the auxiliary blower  600 . 
     Thus, when the main blower  200  operates, inside air or outside air may flow from the first housing  110  to the second housing  120 , and may be supplied into the mobility after the temperature of the inside air or the outside air is adjusted through the evaporator  400  or the internal condenser  300 . 
     Furthermore, when the auxiliary blower  600  operates, internal air may be discharged outside through the internal condenser  300 , the evaporator  400 , and the external condenser  500 . The high-temperature air having passed through the internal condenser  300  may remove condensed water generated in the evaporator  400 , and may exchange heat with the external condenser  500 , whereby a heat pump may be implemented. 
     The internal condenser  300 , the evaporator  400 , the external condenser  500 , and the auxiliary blower  600  may be provided in a straight line in the second housing  120 . 
     Conventionally, the evaporator  400  is provided to be spaced from the internal condenser  300 , and thus it is not possible to remove condensed water and sterilize the evaporator  400  by use of the internal condenser  300  as an exemplary embodiment of the present disclosure. Therefore, in the present disclosure, the internal condenser  300 , the evaporator  400 , the external condenser  500 , and the auxiliary blower  600  may be provided in a straight line, and thus, when the auxiliary blower  600  operates, air may sequentially pass through the internal condenser  300 , the evaporator  400 , and the external condenser  500  and the high-temperature air having passed through the internal condenser  300  may be smoothly supplied to the evaporator  400 . 
     The second housing  120  includes a first space  121 , in which the internal condenser  300  and the evaporator  400  are provided, and a second space  122 , in which the external condenser  500  and the auxiliary blower  600  are provided. The first housing  110  may fluidically-communicate with the first space  121  of the second housing  120  through a first flow channel S 1 , the first space  121  and the second space  122  of the second housing  120  may fluidically-communicate with each other through a second flow channel S 2 , and the flow channel control door  700  may be provided to selectively open or close the first flow channel S 1  and the second flow channel S 2 . 
     Thus, air flowing in the second housing  120  may have a temperature adjusted through the internal condenser  300  and the evaporator  400  of the first space  121 , and may exchange heat with the external condenser  500  of the second space  122 , whereby a heat pump may be implemented. 
     The flow channel control door  700  may selectively open or close the first flow channel S 1 , through which the first housing  110  fluidically-communicates with the second housing  120 , and the second flow channel S 2 , through which connects the first space  121  of the second housing  120  to the second space  122 , so that air flows from the first housing  110  to the second housing  120  through the first flow channel S 1  or air flows from the first space  121  to the second space  122  through the second flow channel S 2 . Furthermore, one flow channel control door  700  may control opening/closing of the first flow channel S 1  and the second flow channel S 2 , whereby the number of elements may be reduced, and thus a package may be miniaturized. 
     In the housing  100 , the temperature adjustment door  910  may be provided between the internal condenser  300  and the evaporator  400 , and air may selectively flow to the internal condenser  300  and the evaporator  400  by the temperature adjustment door  910 . The temperature adjustment door  910  may be provided between the internal condenser  300  and the evaporator  400 , and may operate in a sliding manner or in a rotation manner. Furthermore, the temperature adjustment door  910  may completely or partially open or close the internal condenser  300  or the evaporator  400  so that the temperature of flowing air is adjusted as the flowing air passes through the internal condenser  300  and the evaporator  400 . 
     In the second space  122  of the second housing  120 , a third flow channel S 3 , through which outside air flows, may be formed, and an external flow channel door  920  configured to selectively open or close the third flow channel S 3  may be provided. That is, the external condenser  500  is required to perform heat exchange through air circulation in order to implement the heat pump, the third flow channel S 3 , through which external air flows, may be formed in the second space  122  of the second housing  120  so that the outside air exchanges heat with the external condenser  500 . 
     Furthermore, in the present disclosure, air flowing by operation of the auxiliary blower  600  may exchange heat with the external condenser  500  during sterilization of the evaporator  400  and removal of condensed water, implementing a heat pump. Therefore, the external flow channel door  920  for selectively opening or closing the third flow channel S 3  may be provided. 
     Thus, the external condenser  500  may exchange heat with outside air circulated through the third flow channel S 3 , implementing a heat pump, and may exchange heat with air having passed through the internal condenser  300  and the evaporator  400  during sterilization of the evaporator  400  and removal of condensed water, maintaining the implementation of the heat pump. 
     Thus, while cooling air, the controller  800  may perform control so that the main blower  200  operates, air cooling operation by the evaporator  400  is activated, the flow channel control door  700  opens the first flow channel S 1 , and the temperature adjustment door  910  blocks the flow of air to the internal condenser  300 . 
     That is, as illustrated in  FIG.  5    and  FIG.  6   , when internal air cooling is required, the controller  800  may operate the main blower  200  so that inside air or outside air flows into the mobility. At the instant time, the controller  800  may control refrigerant circulation so that the air cooling operation of the evaporator  400  is activated, may control the flow channel control door  700  to open the first flow channel S 1 , and may control the temperature adjustment door  910  to block the flow of air to the internal condenser  300 . Thus, the inside air or the outside air flowing at the time of operation of the main blower  200  may be cooled by passing through the evaporator  400 , and cooled cooling air may be provided into the mobility. 
     In an exemplary embodiment of the present invention, the temperature adjustment door  910  may include an actuator such as a step motor and electrically connected to the controller  800 . 
     Furthermore, the controller  800  may control the external flow channel door  920  to open the third flow channel S 3  while air is cooled, and thus outside air circulated through the third flow channel S 3  may exchange heat with the external condenser  500 , whereby the heat pump may be implemented. 
     As illustrated in  FIG.  7   , the controller  800  may perform control during air heating so that the main blower  200  operates, the air cooling operation by the evaporator  400  is deactivated, the flow channel control door  700  opens the first flow channel S 1 , and the temperature adjustment door  910  allows the flow of air to the internal condenser  300 . 
     That is, when internal air heating is required, the controller  800  may operate the main blower  200  so that inside air or outside air flows into the mobility. At the instant time, the controller  800  may control refrigerant circulation so that the evaporator  400  is deactivated, may control the flow channel control door  700  to open the first flow channel S 1 , and may control the temperature adjustment door  910  to allow the flow of air of the internal condenser  300 . Thus, inside air or outside air flowing at the time of operation of the main blower  200  may be heated by passing through the internal condenser  300 , and the heated heating air may be provided into the mobility. 
     Furthermore, the controller  800  may control the external flow channel door  920  to open the third flow channel S 3  while air is heated, and thus outside air circulated through the third flow channel S 3  may exchange heat with the external condenser  500 , whereby the heat pump may be implemented. 
     As illustrated in  FIG.  8    and  FIG.  9   , the controller  800  may perform control during the sterilization of the evaporator  400  so that the auxiliary blower  600  operates, air cooling operation by the evaporator  400  is deactivated, the flow channel control door  700  opens the second flow channel S 2 , and the temperature control door allows the flow of air to the internal condenser  300 . 
     That is, when the sterilization of the evaporator  400  and the removal of condensed water are required after internal cooling, the controller  800  may operates the auxiliary blower  600  so that internal air flows in the housing  100  in a direction in which the internal air is discharged to the outside. Thus, when the auxiliary blower  600  operates, internal cooling may be performed, and thus internal dry air may be introduced into the housing  100 , effectively sterilizing the evaporator  400  and effectively removing the condensed water. 
     Furthermore, the controller  800  may control refrigerant circulation so that the evaporator  400  is deactivated, may control the flow channel control door  700  to open the second flow channel S 2 , and may control the temperature adjustment door  910  to allow the flow of air to the internal condenser  300 . Thus, internal air flowing at the time of operation of the auxiliary blower  600  may be heated by passing through the internal condenser  300 , and the heated air may be supplied to the evaporator  400 , sterilizing the evaporator  400  and removing the condensed water. 
     Furthermore, the controller  800  may control the external flow channel door  920  to close the third flow channel S 3  during the sterilization of the evaporator  400 . Thus, internal air flowing during operation of the auxiliary blower  600  may flow through the internal condenser  300 , the evaporator  400 , and the external condenser  500 . Furthermore, during the sterilization of the evaporator  400  and the removal of the condensed water, the external condenser  500  may exchange heat air having passed through with the internal condenser  300  and the evaporator  400 , whereby the implementation of the heat pump may be maintained. 
     The controller  800  may receive information about whether there is a passenger in the mobility when sterilizing the evaporator  400 , and may control the sterilization of the evaporator  400  to be performed when there is no passenger in the mobility. 
     The controller  800  may determine, through a pressure detector provided in a seat or a camera detector configured to image the inside of the mobility, whether there is a passenger in the mobility. The controller  800  may determine whether there is a passenger in the mobility, and may control the sterilization of the evaporator  400  to be performed when the passenger is not present in the mobility, and thus may prevent the passenger from feeling unpleasant and uncomfortable while sterilizing the evaporator  400  by use of internal air. 
     As illustrated in  FIG.  10   , an air-conditioning system for an electric mobility, according to an exemplary embodiment of the present disclosure, may include: a refrigerant line  10  in which a refrigerant is circulated and which includes a compressor  11 , an internal condenser  300 , an external condenser  500 , an expander  12 , and an evaporator  400 ; and a coolant line  20  in which a coolant is circulated and which includes a heat exchanger  21 , in which the coolant exchanges heat with the refrigerant, a valve  22 , an electronic equipment module  23 , a battery module  24 , and a radiator  25 . 
     The coolant line  20  may include a first coolant line  20   a , which includes the radiator  25 , a first heat exchanger  21   a , a reservoir (RV), a first water pump  26   a , the electronic equipment module  23 , and a first valve  22   a , and a second coolant line  20   b , which branches from the reservoir (RV) of the first coolant line  20   a  and includes a second valve  22   b , the battery module  24 , a second water pump  26   b , and a second heat exchanger  21   b.    
     Furthermore, the refrigerant line  10  may include a first refrigerant line  10   a , which includes the compressor  11 , the internal condenser  300 , the first heat exchanger  21   a , a first expander  12   a , the external condenser  500 , a second expander  12   b , and the evaporator  400 , and a second refrigerant line  10   b , which branches from the first refrigerant line  10   a , is connected to the compressor  11 , and includes a third expander  12   c  and the second heat exchanger  21   b.    
     In the first refrigerant line  10   a  and the first coolant line  20   a , a refrigerant and a coolant may exchange with each other through the first heat exchanger  21   a , and in the second refrigerant line  10   b  and the second coolant line  20   b , a refrigerant and a coolant may exchange heat with each other through the second heat exchanger  21   b.    
     Furthermore, the refrigerant line  10  may further include an accumulator configured to circulate a refrigerant, and an additional heater  30  and/or additional heat exchangers  31  and  32  configured to improve the efficiency of heat exchange between a refrigerant and a coolant. 
     Thus, in the present disclosure, at the time of cooling/heating, a heat pump may be implemented, ensuring air-conditioning efficiency. 
     In an exemplary embodiment of the present disclosure, while air is cooled, the first expander  12   a  may be opened, and the second expander  12   b  and the third expander  12   c  may expand a refrigerant. The first valve  22   a  and the second valve  22   b  are switched so that coolant is circulated in the first coolant line  20   a  and the second coolant line  20   b , respectively. 
     When the main blower  200  operates, air may have a temperature adjusted by passing through the evaporator  400  or the internal condenser  300 , and then may flow into the mobility, and the flow channel control door  700  is opened and operated. 
     That is, as illustrated in  FIG.  11   , a refrigerant compressed in the compressor  11  may condensed by dissipating heat while circulating through the internal condenser  300 , the first heat exchanger  21   a , and the external condenser  500 , and then may be expanded by the second expander  12   b . Thus, the refrigerant may be evaporated in the evaporator  400 , and thus air passing through the evaporator  400  may be cooled. 
     In the first coolant line  20   a , a coolant may cool the electronic equipment module  23 , and the coolant cooled through the radiator  25  may exchange heat with the refrigerant through the first heat exchanger  21   a  so that a refrigerant is cooled in the first heat exchanger  21   a . Furthermore, in the second coolant line  20   b , a coolant having a temperature increased by cooling the battery module  24  may exchange heat with a refrigerant in the second heat exchanger  21   b , and thus may have an adjusted temperature at which the coolant can cool the battery module  24 . 
     Thus, air to be provided into the mobility may be cooled. 
     In present disclosure, heating air to be provided into the mobility, which is a process for sterilization of the evaporator  400  and removal of condensed water after cooling, is an exemplary embodiment of the heat pump process, and a description thereof will be omitted. 
     As illustrated in  FIG.  12   , when sterilizing the evaporator  400 , the first expander  12   a  may expand the refrigerant, the second expander  12   b  may be closed, the third expander  12   c  may be opened, and the first valve  22   a  and the second valve  22   b  may be switched so that the coolant is circulated in the second coolant line  20   b , together with the first water pump  26   a  and the electronic equipment module  23  of the first coolant line  20   a.    
     At the present time, the auxiliary blower  600  may operate so that air is heated through the internal condenser  300  and then provided to the evaporator  400 , and the flow channel control door  700  may be closed and operated. 
     The refrigerant compressed in the compressor  11  may be condensed by dissipating heat while circulating through the internal condenser  300  and the first heat exchanger  21   a , and then the refrigerant may be expanded by the first expander  12   a . Thus, in the second heat exchanger  21   b , the low-temperature refrigerant may exchange heat with the coolant, and thus the coolant may be cooled. 
     Furthermore, the sterilization of the evaporator  400  and the removal of condensed water may be performed while there is no passenger, and thus the temperature of the electronic equipment module  23  and the battery module  24  may become relatively low. Therefore, cooling of the electronic equipment module  23  and the battery module  24  may be smoothly performed only by heat exchange made through the second heat exchanger  21   b    
     In the air-conditioning apparatus for an electric mobility, having the above-described structure, and the air-conditioning system for an electric mobility, using the same, a heat pump may be used to provide high-temperature air generated through an internal condenser to an evaporator, removing condensed water generated in the evaporator after cooling, and sterilizing the evaporator. 
     In an exemplary embodiment of the present invention, a branch line  35  is provided on the second coolant line  20   b  connecting between the second valve  22   b  and the second water pump  26   b  and the second water pump  26   b  and the second heat exchanger  21   b.
