The thermoelectric unit 100 is installed on the movable body to control the internal temperature of the movable body. In addition, the heat dissipation unit 200 may remove waste heat generated from the thermoelectric unit 100. Accordingly, performance of the thermoelectric unit 100 may be maintained. In addition, the ventilation unit 300 may discharge the air inside the mobile body to the outside of the mobile body. In addition, the ventilation unit 300 may supply external air of the mobile body to the interior of the mobile body. At this time, the ventilation unit 300 may induce heat exchange between the discharged air and the supplied air. In addition, the ventilation unit 300 may control the humidity of the supplied air. The control unit 400 may control the operation of the thermoelectric unit 100, the heat dissipation unit 200, and the ventilation unit 300 based on the external air of the mobile body.

Hereinafter, each configuration of the air conditioning apparatus 1000 will be described in detail.

The thermoelectric unit 100 may handle a sensible heat load inside the mobile body. Specifically, the thermoelectric unit 100 may control the internal temperature of the moving body. For example, the thermoelectric unit 100 may increase or decrease the internal temperature of the mobile body. Further, the moving object may be provided as a land moving object such as a train or a car or an aerial moving object such as a drone or an airplane.

In addition, the thermoelectric unit 100 may be operated based on the external temperature of the mobile body. For example, the thermoelectric unit 100 may be operated in a heating mode when the external temperature is lower than a predetermined temperature. In addition, the thermoelectric unit 100 may be operated in a cooling mode when the external temperature is higher than a predetermined temperature.

In addition, the thermoelectric unit 100 may be installed on one side of the moving body. For example, the thermoelectric unit 100 is installed on the upper side of the mobile body, and can transfer warm or cold heat from the upper side of the mobile body to the inside of the mobile body.

In addition, the thermoelectric unit 100 may adjust the internal temperature of the moving body using radiant heat. For example, the thermoelectric unit 100 may be provided in the form of a radiation panel to provide radiant heat to the interior of the moving object.

In addition, the thermoelectric unit 100 according to an embodiment may include a thermoelectric element 110.

The thermoelectric element 110 may convert electrical energy into thermal energy. Specifically, the thermoelectric element 110 may include two surfaces facing each other. At this time, when a current is applied to the thermoelectric element 110, one surface of the thermoelectric element 110 may absorb heat and the other surface may generate heat by the Peltier effect. Accordingly, the temperature of the one surface may be lowered, and the temperature of the other surface may be increased.

In addition, the amount of heat absorbed or the amount of heat generated by the thermoelectric element 110 may vary according to the amount of current applied to the thermoelectric element 110. For example, as the amount of current applied to the thermoelectric element 110 increases, the amount of heat absorbed or the amount of heat generated by the thermoelectric element 110 may increase.

In addition, the heat absorbing surface or the heating surface of the thermoelectric element 110 may vary depending on the direction of the current applied to the thermoelectric element 110. For example, when a current having a first direction is applied to the thermoelectric element 110, one surface of the thermoelectric element 110 may be an endothermic surface, and the other surface may be a heating surface. Conversely, when a current having a second direction opposite to the first direction is applied to the thermoelectric element 110, one surface of the thermoelectric element 110 may be a heating surface, and the other surface may be an endothermic surface. .

In addition, the heat absorbing surface or the heating surface of the thermoelectric element 110 may be switched as the direction of the current applied to the thermoelectric element 110 changes. For example, when a current having a first direction is applied to the thermoelectric element 110, the heat absorbing surface of the thermoelectric element 110 is a heating surface when the direction of the current is changed to a second direction opposite to the first direction. Can be converted to Likewise, when a current having a first direction is applied to the thermoelectric element 110, the heating surface of the thermoelectric element 110 is switched to an endothermic surface when the direction of the current changes in a second direction opposite to the first direction. Can be.

In addition, the thermoelectric element 110 may provide heat. Specifically, the thermoelectric element 110 may be operated in at least one operation mode of a heating mode providing warm heat and a cooling mode providing cold heat. For example, when the external temperature of the moving body is higher than a predetermined temperature, the thermoelectric element 110 may be operated in a cooling mode. In addition, when the external temperature of the moving body is lower than a predetermined temperature, the thermoelectric element 110 may be operated in a heating mode.

Specifically, when the thermoelectric element 110 is operated in a heating mode, one of the two surfaces of the thermoelectric element 110 close to the moving body may be a heating surface, and the other surface far from the moving body may be an endothermic surface. Likewise, when the thermoelectric element 110 is operated in a cooling mode, one of the two surfaces of the thermoelectric element 110 close to the moving body may be an endothermic surface, and the other surface distant from the moving body may be a heating surface.

In addition, the thermoelectric unit 100 according to an embodiment may include a heat transfer member 120.

The heat transfer member 120 may be thermally connected to the thermoelectric element 110. For example, the heat transfer member 120 may contact one surface of the thermoelectric element 110.

Also, the heat transfer member 120 may obtain heat provided from the thermoelectric element 110. For example, the heat transfer member 120 may obtain the heat by absorbing heat radiated from the thermoelectric element 110.

In addition, the heat obtained by the heat transfer member 120 may vary depending on the operation mode of the thermoelectric element 110. For example, when the operation mode of the thermoelectric element 110 is the heating mode, the heat transfer member 120 may obtain warm heat from the thermoelectric element 110. In addition, when the operation mode of the thermoelectric element 110 is the cooling mode, the heat transfer member 120 may obtain cold heat from the thermoelectric element 110.

In addition, the heat transfer member 120 may transfer heat provided from the thermoelectric element 110 to the interior of the mobile body. Specifically, the heat transfer member 120 may transfer warm or cold heat to the interior of the mobile body according to the operation mode of the thermoelectric element 110. For example, when the operation mode of the thermoelectric element 110 is the heating mode, the heat transfer member 120 may transmit warm heat to the inside of the moving body. In addition, when the operation mode is the cooling mode, the heat transfer member 120 may transmit cold heat to the inside of the moving body.

In addition, the thermoelectric unit 100 according to an embodiment may include an insulating material 130.

The heat insulating material 130 may prevent heat exchange between the heat absorbing surface and the heat absorbing surface of the thermoelectric element 110. Specifically, the heat insulating material 130 can prevent the heat generated from the heat generating surface of the thermoelectric element 110 from being transferred to the heat absorbing surface of the thermoelectric element 110. Accordingly, a temperature difference between the heat absorbing surface and the heat generating surface of the thermoelectric element 110 can be maintained.

On the other hand, when the thermoelectric element 110 is operated in the cooling mode, the heat absorbing surface of the thermoelectric element 110 is disposed in a region close to the heat transfer member 120 to provide cold heat to the heat transfer member 120, and the thermoelectric element The heating surface of 110 may be disposed in a region far from the heat transfer member 120.

Accordingly, the air conditioning apparatus 1000 according to an embodiment may include a heat dissipation unit 200 for dissipating heat generated from the thermoelectric element 110.

For example, the heat dissipation unit 200 according to an embodiment may remove waste heat generated from the thermoelectric element 110. Specifically, the heat dissipation unit 200 may remove the heat generated from the heating surface of the thermoelectric element 110 when the thermoelectric element 110 is operated in the cooling mode. Accordingly, the cooling performance of the thermoelectric element 110 can be maintained.

In addition, the heat dissipation unit 200 according to an embodiment may be thermally connected to the thermoelectric element 110 to absorb waste heat generated from the thermoelectric element 110. For example, the heat dissipation unit 200 may be connected to the heating surface of the thermoelectric element 110 to absorb the heat generated from the heating surface. In addition, the heat dissipation unit 200 is connected to the heat absorbing surface of the thermoelectric element 110, and can absorb cold heat generated from the heat absorbing surface.

In addition, the heat dissipation unit 200 according to an embodiment may discharge the waste heat absorbed from the thermoelectric element 110 to the outside of the mobile body. At this time, the heat dissipation unit 200 may discharge the absorbed waste heat to the outside of the mobile body through heat exchange between the absorbed waste heat and the outside air of the mobile body. Accordingly, the performance of the thermoelectric element 110 can be maintained.

In addition, the air conditioning apparatus 1000 according to an embodiment may include a ventilation unit 300.

The ventilation unit 300 according to an embodiment may induce circulation of air inside the mobile body. For example, the ventilation unit 300 may discharge air inside the mobile body to the outside of the mobile body. In addition, the ventilation unit 300 may supply air outside the mobile body into the mobile body. Accordingly, the cleanliness of the air inside the moving body can be improved.

At this time, the ventilation unit 300 may induce heat exchange between air discharged from the inside of the mobile body to the outside of the mobile body and air supplied from the outside of the mobile body to the interior of the mobile body. Accordingly, the temperature of the air supplied from the outside of the movable body to the inside of the movable body may be changed. For example, when the temperature of the air discharged from the inside of the mobile body to the outside of the mobile body is lower than the temperature of the air supplied from the outside of the mobile body to the inside of the mobile body, the temperature of the air supplied to the mobile body is different from the air discharged to the outside of the mobile body. It can be reduced through heat exchange. Similarly, when the temperature of the air discharged from the inside of the mobile body to the outside of the mobile body is higher than the temperature of the air supplied from the outside of the mobile body to the inside of the mobile body, the temperature of the air supplied to the mobile body is heat exchanged with the air discharged outside the mobile body Can increase through

In addition, the ventilation unit 300 can handle the latent heat load inside the mobile body. For example, the ventilation unit 300 may lower the humidity of the air inside the mobile body. Specifically, the ventilation unit 300 may lower the humidity of air supplied from the outside of the mobile body to the interior of the mobile body. In addition, the ventilation unit 300 may control the temperature of the air inside the mobile body.

In addition, the ventilation unit 300 according to an embodiment may be operated based on information of air outside the mobile body. For example, when the humidity of the air outside the mobile body is higher than a predetermined humidity, the ventilation unit 300 may lower the humidity of air supplied from the outside of the mobile body to the inside of the mobile body.

In addition, the air conditioning apparatus 1000 according to an embodiment may include a control unit 400.

The control unit 400 according to an embodiment may control the thermoelectric unit 100. For example, the control unit 400 may control the operation of the thermoelectric element 110. Specifically, the control unit 400 may control the operation mode of the thermoelectric element 110.

In addition, the control unit 400 according to an embodiment may operate the thermoelectric element 110 based on the information of the air outside the mobile body. For example, when the temperature of the air outside the moving body is higher than a predetermined temperature, the thermoelectric element 110 may be operated in a cooling mode. In addition, when the temperature of the air outside the moving body is lower than a predetermined temperature, the thermoelectric element 110 may be operated in a heating mode.

At this time, the control unit 400 may change the direction of the current applied to the thermoelectric element 110. For example, when the operation mode of the thermoelectric element 110 is switched from the cooling mode to the heating mode, the control unit 400 changes the direction of the current applied to the thermoelectric element 110, thereby changing the direction of the current applied to the thermoelectric element 110. The operation mode can be controlled.

In addition, the control unit 400 may adjust the intensity of the current applied to the thermoelectric element 110. For example, the control unit 400 may adjust the intensity of the current applied to the thermoelectric element 110 based on the temperature of the outside air of the moving object. Specifically, when the thermoelectric element 110 is operated in the cooling mode, the intensity of the first current applied when the temperature of the outside air of the moving body is the first temperature is the first temperature of the outside of the moving body is lower than the first temperature When the temperature is 2, it may be greater than the intensity of the second current applied.

In addition, the control unit 400 according to an embodiment may control the heat dissipation unit 200. For example, the control unit 400 may control the operation of the heat dissipation unit 200 based on the moving speed of the moving object. Specifically, when the moving speed of the moving body is lower than a predetermined speed, the control unit 400 may operate the heat dissipation unit 200. In addition, the control unit 400 may operate the heat dissipation unit 200 when the moving body is stopped.

In addition, the control unit 400 according to an embodiment may control the ventilation unit 300. For example, the control unit 400 may control the operation of the ventilation unit 300 based on the information of the air inside the moving object. Specifically, when the humidity of the outside air of the mobile body is higher than a predetermined humidity, the control unit 400 may operate the ventilation unit 300 to lower the humidity of the air supplied from the outside of the mobile body to the inside. In addition, when the temperature of the air outside the mobile body is lower than a predetermined temperature, the control unit 400 may operate the ventilation unit 300 to increase the temperature of the air supplied from the outside of the mobile body to the inside.

In addition, although not shown, the air conditioning apparatus 1000 according to an embodiment may include an air information acquisition sensor.
