Description

  The present disclosure relates to a portable air conditioner and an air conditioning system including the portable air conditioner.

  Conventionally, an air conditioning system has been proposed that can simultaneously improve comfort and reduce power consumption. For example, Patent Document 1 describes an air conditioning system 100 including an indoor unit 121 and an outdoor unit 122 (air conditioner), as shown in FIG. 6A. The air conditioning system 100 is equipped with a vapor compression refrigeration cycle, and the indoor unit 121 and the outdoor unit 122 are connected via a refrigerant pipe 123 through which a refrigerant flows and a communication line 124.

  As shown in FIG. 6B, the indoor unit 121 is installed on, for example, an upper part of a wall of the indoor space A, and the indoor space A is cooled and heated by cold air and hot air blown from the indoor unit 121. The indoor unit 121 is equipped with an indoor fan 125a. The indoor blower 125a sucks the air in the indoor space A, passes through the indoor heat exchanger 125, and then blows it out again into the indoor space A. The indoor unit 121 is equipped with an intake air temperature sensor 131 and an infrared sensor 133. The intake air temperature sensor 131 detects the intake air temperature of the indoor unit 21 that air-conditions the indoor space A. The infrared sensor 133 detects the surface temperature of the ceiling, floor, human being, etc. in the indoor space A. In FIG. 6B, the sensor detection range of the infrared sensor 133 is indicated by a broken line.

  Information detected by the intake air temperature sensor 131 and the infrared sensor 133 is transmitted to the measurement control device 130 of the indoor unit 121. The measurement control device 130 is based on information from the intake air temperature sensor 131, the infrared sensor 133, and other various sensors mounted on the air conditioning system 100, the operation information of the air conditioner, and the setting information of the occupants. The air conditioning system 100 is controlled. For example, the measurement control device 130 controls the air conditioning system 100 according to the set temperature set by the remote controller 132 or the like.

  As illustrated in FIG. 6C, the measurement control device 130 includes a temperature acquisition unit 140, a height determination unit 141, a calculation unit 142, and a control unit 143. The temperature acquisition unit 140 acquires the temperature of the indoor space A at different heights. The temperature of the indoor space A is obtained from, for example, the sensor output of the infrared sensor 133 (two-dimensional image data, that is, the temperature distribution of the indoor space A). Further, the temperature acquisition unit 140 acquires the surface temperature of an object (for example, a floor) facing the occupant in the indoor space A based on the two-dimensional image data. Based on the two-dimensional image data, the temperature acquisition unit 140 acquires the surface temperature of an object (for example, a floor) in contact with the occupant in the indoor space A. Moreover, the temperature acquisition means 140 acquires a occupant's surface temperature based on two-dimensional image data. The height determining means 141 determines the height according to the occupant's posture based on information related to the occupant's posture in the indoor space A. Based on the temperature acquired by the temperature acquisition unit 140, the calculation unit 142 calculates a sensible temperature at a height corresponding to the occupant's posture determined by the height determination unit 141. The control unit 143 controls the air conditioner based on the sensible temperature calculated by the calculation unit 142.

  As shown in FIG. 7, Patent Document 2 includes an air conditioner unit 302, a multi-function blower unit 303, and a remote controller 304 in a state in which bidirectional communication is possible so that they can exchange information with each other. A connected air conditioning system 300 is described. The air conditioner unit 302 includes an indoor unit 305 installed indoors, an outdoor unit 306 installed outdoors, and a control unit. The air conditioning system 300 includes position information collection means for collecting relative position information between the indoor unit 305 and the multi-function blower unit 303. The control unit blows out air from the indoor unit 305 to the multi-function blower unit 303 based on the position information obtained by the position information collecting means, and the multi-function blower unit 303 relays the air to any arbitrary Send it to the destination. Thereby, the conditioned air generated by the indoor unit 305 can be delivered to an arbitrary place in the room.

The internal heat exchange unit 33 is disposed inside the housing 20. The internal heat exchange unit 33 heats or cools the air so as to generate conditioned air from the air that has passed through the suction port 22 and is sucked into the housing 20. The external heat exchange unit 31 has a heat transfer surface 31 a for contacting the heat source 60 existing outside the housing 20. The external heat exchange unit 31 receives heat from the heat source 60 or dissipates heat to the heat source 60 via the heat transfer surface 31a. Here, the heat source 60 may be a solid such as the floor of the indoor A, or may be a fluid such as air near the floor 12a. The heat transport mechanism 35 is disposed inside the housing 20. The heat transport mechanism 35 is a mechanism for transporting heat between the internal heat exchange unit 33 and the external heat exchange unit 31. The portable air conditioner 11 a includes a blower 36 disposed inside the housing 20, for example. The blower 36 is, for example, a propeller fan. By the function of the blower 36, air is sucked into the inside of the housing 20 from the suction port 22, and the sucked air passes through the internal heat exchange unit 33 and then blows out from the blowout port 21 as conditioned air. The portable air conditioner 11a performs local heating or cooling of the space around itself.

The external heat exchange unit 31 is, for example, a heat exchanger for exchanging heat between the heat source 60 and the refrigerant. The external heat exchanging unit 31 includes, for example, a plate that forms the heat transfer surface 31a and a pipe that forms the flow path 31b for the refrigerant, and the plate and the tube are joined together. In addition, the heat transfer surface 31a may not be provided with a plate, but may be formed by the outer peripheral surface of the piping that forms the flow path 31b for the refrigerant. The plate or pipe forming the heat transfer surface 31a is made of a metal such as copper or a resin material, for example. The heat transport mechanism 35 includes, for example, a compressor 35a for compressing the refrigerant, a decompression mechanism 35b for decompressing the refrigerant, and a flow path 34 for the refrigerant. The flow path 34 for the refrigerant is formed, for example, so that the heat transport mechanism 35 constitutes the vapor compression refrigeration cycle 30 together with the internal heat exchange unit 33 and the external heat exchange unit 31. The compressor 35a is, for example, a positive displacement compressor such as a rotary compressor or a scroll compressor. The decompression mechanism 35b is, for example, an expansion valve or a capillary tube. The refrigerant is not particularly limited, and for example, fluorocarbon (fluorocarbon), hydrofluoroolefin, hydrocarbon, carbon dioxide and the like can be used.

  The heat transport mechanism 35 further includes, for example, a switching mechanism 35c. The switching mechanism 35 c is disposed inside the housing 20. In the switching mechanism 35c, the refrigerant discharged from the compressor 35a passes through the external heat exchange unit 31, the decompression mechanism 35b, and the internal heat exchange unit 33 in this order, and the refrigerant discharged from the compressor 35a is The state which passes the internal heat exchange part 33, the pressure reduction mechanism 35b, and the external heat exchange part 31 in this order is switched. Thereby, the heating operation and the cooling operation of the portable air conditioner 11a can be switched. The switching mechanism 35c is, for example, a four-way valve. The flow path 34 for the refrigerant includes a flow path 34a to a flow path 34f. The flow path 34 a is a flow path that connects the external heat exchange unit 31 and the decompression mechanism 35 b, and is connected to one end of the flow path 31 b for the refrigerant in the external heat exchange unit 31. The flow path 34 b is a flow path that connects the decompression mechanism 35 b and the internal heat exchange unit 33, and is connected to one end of the flow path 33 b for the refrigerant in the internal heat exchange unit 33. The flow path 34 c is a flow path that connects the internal heat exchange unit 33 and the switching mechanism 35 c, and is connected to the other end of the flow path 33 b for the refrigerant in the internal heat exchange unit 33. The flow path 34d is a flow path that connects the switching mechanism 35c and the compressor 35a, and is connected to the suction port of the compressor 35a. The flow path 34e is a flow path that connects the compressor 35a and the switching mechanism 35c, and is connected to the discharge port of the compressor 35a. The flow path 34 f is a flow path that connects the switching mechanism 35 c and the external heat exchange unit 31, and is connected to the other end of the flow path 31 b for the refrigerant in the external heat exchange unit 31.

  When the portable air conditioner 11 a performs the heating operation, the internal heat exchange unit 33 heats the air that has passed through the suction port 22 and is sucked into the housing 20. In this case, the switching mechanism 35c forms a flow path indicated by a broken line in FIG. 2, and the refrigerant flows in the vapor compression refrigeration cycle 30 as indicated by a broken line arrow. The low-temperature and low-pressure refrigerant is supplied to the flow path 31b for the refrigerant of the external heat exchange unit 31 through the flow path 34a. The external heat exchange unit 31 receives heat from the heat source 60 via the heat transfer surface 31a, whereby the refrigerant flowing through the flow path 31b is heated. The heated refrigerant passes through the flow path 34f, the switching mechanism 35c, and the flow path 34d, and is sucked into the compressor 35a. The compressor 35a compresses the refrigerant and discharges a high-temperature and high-pressure refrigerant gas. The high-temperature and high-pressure refrigerant gas passes through the flow path 34e, the switching mechanism 35c, and the flow path 34c and is supplied to the internal heat exchange unit 31. In the internal heat exchanging section 31, heat exchange is performed between the air that has passed through the suction port 22 and is sucked into the housing 20 and the refrigerant. Thereby, air is heated and the air-conditioning wind for heating is produced | generated, and the refrigerant | coolant which flows through the flow path 33b is cooled. The cooled refrigerant passes through the flow path 34b and is guided to the decompression mechanism 35b. In the decompression mechanism 35b, the refrigerant is decompressed, and a low-temperature and low-pressure refrigerant is generated.

  When the portable air conditioner 11a performs the cooling operation, the internal heat exchange unit 33 cools the air that has passed through the suction port 22 and is sucked into the housing 20. In this case, the switching mechanism 35c forms a flow path indicated by a solid line in FIG. 2, and the refrigerant flows in the vapor compression refrigeration cycle 30 as indicated by a solid arrow. The high-temperature and high-pressure refrigerant discharged from the compressor 35a is supplied to the flow path 31b for the refrigerant of the external heat exchange unit 31 through the flow path 34e, the switching mechanism 35c, and the flow path 34f. In the external heat exchange unit 31, heat exchange is performed between the refrigerant and the heat source 60. That is, the external heat exchanging unit 31 dissipates heat to the heat source 60 through the heat transfer surface 31a, whereby the refrigerant flowing through the flow path 31b is cooled. The cooled refrigerant passes through the flow path 34a and is guided to the decompression mechanism 35b. In the decompression mechanism 35b, the refrigerant is decompressed, and a low-temperature and low-pressure refrigerant is generated. The low-temperature and low-pressure refrigerant passes through the flow path 34b and is supplied to the internal heat exchanger 33. In the internal heat exchange unit 31, heat exchange is performed between the air that has passed through the suction port 22 and is sucked into the housing 20 and the refrigerant. Thereby, air is cooled and the air-conditioning wind for cooling is produced | generated, and the refrigerant | coolant which flows through the flow path 31b is heated. The heated refrigerant passes through the flow path 34c, the switching mechanism 35c, and the flow path 34d and is sucked into the compressor 35a. The compressor 35a compresses the refrigerant and discharges a high-temperature and high-pressure refrigerant gas.

  As shown in FIG. 2, the portable air conditioner 11 a includes, for example, a controller 37, a heat transfer surface temperature sensor 38, an intake air temperature sensor 39, an infrared sensor 40, and a display panel 43. The heat transfer surface temperature sensor 38 is a sensor for detecting the temperature of the heat transfer surface 31a. The suction air temperature sensor 39 is a sensor for detecting the temperature of the air that has passed through the suction port 22 and is sucked into the housing 20. The infrared sensor 40 is, for example, a sensor for detecting the surface temperature of an indoor A object (including a resident in the indoor A). The display panel 43 is a display panel for displaying information related to the setting of the air conditioning temperature, or information related to the strength of the air blown by the blower 36 or the wind direction. The controller 37 is connected to each of the heat transfer surface temperature sensor 38, the intake air temperature sensor 39, and the infrared sensor 40 by wire or wirelessly. As a result, signals indicating detection values (detection temperatures) in the heat transfer surface temperature sensor 38, the intake air temperature sensor 39, and the infrared sensor 40 are input to the controller 37.

  The controller 37 adjusts the target value of the air conditioning temperature based on the detected values (detected temperatures) of these sensors. For example, the controller 37 adjusts the target value of the air conditioning temperature of the portable air conditioner 11a based on the detection value of the heat transfer surface temperature sensor 38. Specifically, when the portable air conditioner 11a performs the heating operation, the controller 37 sets the target of the air conditioning temperature of the portable air conditioner 11a when the detection value of the heat transfer surface temperature sensor 38 is relatively low. Set the value relatively high. In addition, when the detected value of the heat transfer surface temperature sensor 38 is relatively high, the controller 37 sets the target value of the air conditioning temperature of the portable air conditioner 11a to be relatively low. When the portable air conditioner 11a performs the cooling operation, the controller 37 relatively sets the target value of the air conditioning temperature of the portable air conditioner 11a when the detected value of the heat transfer surface temperature sensor 38 is relatively high. Set to low. Further, when the detected value of the heat transfer surface temperature sensor 38 is relatively low, the controller 37 sets the target value of the air conditioning temperature of the portable air conditioner 11a to be relatively high.

  For example, the controller 37 sets the target of the air conditioning temperature of the portable air conditioner 11a based on the detection value (detection temperature) of the infrared sensor 40 or the suction air temperature sensor 39 in addition to the detection value of the heat transfer surface temperature sensor 38. The value may be adjusted. For example, the controller 37 may adjust the target value of the air conditioning temperature of the portable air conditioner 11a based on the surface temperature of the occupant in the room A detected by the infrared sensor 40. Further, the target value of the air conditioning temperature of the portable air conditioner 11a is adjusted based on the detected value (detected temperature) of an external temperature sensor (not shown) that detects the temperature of a specific object outside the housing 20. Also good. For example, a temperature sensor that measures the body temperature of a specific occupant in the room A is provided as an external temperature sensor, and the target value of the air conditioning temperature of the portable air conditioner 11a based on the detected value (detected temperature) of the temperature sensor. May be adjusted. Moreover, the controller 37 receives the input of the setting information regarding the air conditioning by the portable air conditioner 11a from a remote controller (not shown), and adjusts the target value of the air conditioning temperature of the portable air conditioner 11a based on this setting information. May be.

  The controller 37 is further connected to each of the compressor 35a, the decompression mechanism 35b, the switching mechanism 35c, the blower 36, and the display panel 43 by wire or wirelessly. The controller 37 controls the compressor 35a, the pressure reducing mechanism 35b, the switching mechanism 35c, and the blower 36 based on the target value of the air conditioning temperature adjusted as described above. For example, the controller 37 controls the rotational speed of the compressor 35 a, the opening degree of the decompression mechanism 35, switching of the state of the switching mechanism 35 c, and the rotational speed of the blower 36.

  As shown in FIG. 2, the portable air conditioner 11a further includes, for example, a wireless power receiver 70 for receiving electric power necessary for operation of the portable air conditioner 11a by non-contact power transmission. In this case, the air conditioning system 10 further includes a power feeder 75 for sending power to the wireless power receiver 70 by contactless power transmission, as shown in FIG. The wireless power receiver 70 is disposed, for example, inside the housing 20. The power feeder 75 is attached to the wall of the indoor A, for example. The power feeder 75 may be embedded in the floor of the indoor A. The method of non-contact power transmission is not particularly limited, but is, for example, an electromagnetic induction method or an electromagnetic resonance method. The portable air conditioner 11a may include a battery for supplying electric power necessary for the operation of the portable air conditioner 11a, instead of the wireless power receiver 70.

  The moving mechanism 42 is not particularly limited as long as the portable air conditioner 11a can be moved along the floor surface 12a of the indoor A. As shown in FIGS. 3 and 4, the moving mechanism 42 includes, for example, a wheel 42 a attached to the bottom surface of the housing 20. The number of wheels 42a included in the moving mechanism 42 is not particularly limited, but is preferably three or more. The moving mechanism 42 includes, for example, a motor (not shown), and at least one wheel is rotationally driven by the motor. Further, as shown in FIG. 1, the controller 37 is connected to the moving mechanism 42 wirelessly or by wire, and controls the moving mechanism 42 so as to adjust the rotational speed, rotational direction, and direction of the wheel 42a. For example, the controller 37 controls the moving mechanism 42 so as to adjust the distance between the portable air conditioner 11a and the occupant based on the detection value in the infrared sensor 40. When the controller 37 determines that the distance between the portable air conditioner 11a and the occupant is greater than a predetermined distance based on the detection value of the infrared sensor 40, the portable air conditioner 11a is set to the occupant. The moving mechanism 42 is controlled to approach. In addition, the portable air conditioner 11a transmits a specific signal such as an ultrasonic signal to the outside of the portable air conditioner 11a, and receives a signal echo (not shown) or camera. (Not shown) may be further provided. In this case, the signal transmitter / receiver or the camera is connected to the controller 37 by wire or wirelessly, and the controller 37 adjusts the distance from the occupant based on the detection result of the signal receiver / transmitter or the imaging result of the camera. The movement mechanism 42 may be controlled to do so.

  As shown in FIGS. 3 and 4, the housing 20 includes a suction port 22 a and a suction port 22 b as the suction port 22. On the side surface of the housing 20, a plurality of suction ports 22a are formed in the height direction (Z-axis direction) of the portable air conditioner 11a. A louver 44 for opening and closing each suction port 22 a is attached to the side surface of the housing 20. The louver 44 is opened and closed by a motor (not shown). For example, the controller 37 controls the motor so that the louver 44 is opened when the portable air conditioner 11a is in operation, and the louver 44 is closed when the portable air conditioner 11a is not in operation. To do. The louver 44 is opened in a state of being inclined downward from the side surface of the housing 20 toward the floor surface 12a. When the air conditioning system 10 includes, for example, a heat pump type floor cooling / heating device as the heat source temperature adjusting device 15, the temperature of the air near the floor surface 12a is acceptable as compared with the temperature of the air away from the floor surface 12a. It is higher when the portable air conditioner 11a is in a heating operation, and lower when the portable air conditioner 11a is in a cooling operation. For this reason, when the louver 44 is opened as described above, higher-temperature air passes through the suction port 22a and is sucked into the housing 20 when the portable air conditioner 11a is heated. Further, when the portable air conditioner 11a is cooled, cooler air passes through the suction port 22a and is sucked into the housing 20. Thereby, the power consumption required for heating or cooling the air in the internal heat exchanger 33 can be reduced.

  As shown in FIG. 3, a plurality of suction ports 22 b are formed in the peripheral portion of the bottom surface of the housing 20 in a state spaced apart at a predetermined interval in the circumferential direction. The suction port 22 b is formed as a through hole that penetrates the bottom wall that forms the bottom surface of the housing 20, and the internal space of the housing 20 communicates with the external space of the housing 20 through this through hole. Air is sucked in through the suction port 22a from the side of the housing 20 or from the lower side of the housing 20 through the suction port 22b by the function of the blower 36 disposed inside the housing 20. . The arrow of the dashed-dotted line in FIG. In this case, dust existing on the floor surface 12a is sucked together with air from the suction port 22, particularly the suction port 22b. For example, a floor that inhibits heat exchange in the external heat exchanging portion 31 via the heat transfer surface 31a by sucking dust together with air from the suction port 22 by the action of the blower 36 during the movement of the portable air conditioner 11a. The dust on the surface 12a can be removed.

  As shown in FIGS. 3 and 4, the portable air conditioner 11 a further includes a cover 23. The cover 23 is attached to the side surface of the housing 20 so as to be positioned outside the wheel 42 a in the vicinity of the bottom surface of the housing 20. A gap is formed between the cover 23 and the floor 12a. The wheel 23 a is protected by the cover 23.

  As shown in FIG. 4, an air outlet 21 is formed in the central portion of the ceiling surface of the housing 20. The blower outlet 21 is covered with the guard member 49, for example. The guard member 49 has an annular frame that engages with the housing 20 in the vicinity of the air outlet 21 and a resin or metal mesh that is attached to the frame. Below the guard member 49, for example, a blower 36 is disposed. The guard member 49 can prevent the blower 36 from coming into contact with a foreign object or a occupant from the outside of the housing 20. For example, an internal heat exchanger 33 is disposed below the blower 36. For example, the infrared sensor 40 is disposed on the ceiling surface of the housing 20 and detects the surface temperature of an object (including a resident) above the housing 20. Moreover, the display panel 43 is arrange | positioned at the ceiling surface of the housing | casing 20, for example.

  A casing 46 is disposed in the internal space of the housing 20. Inside the casing 46, for example, a compressor 35a, a pressure reducing mechanism 35b, and a switching mechanism 35c are accommodated. An air flow path is formed outside the casing 46 in the internal space of the housing 20. For example, the controller 37 and the power receiver 70 are disposed outside the casing 46 in the internal space of the housing 20. Thereby, the controller 37 can be cooled by the air flowing inside the housing 20.

  The portable air conditioner 11a further includes a humidity control mechanism 41 disposed inside the housing 20, for example. For example, the humidity control mechanism 41 is disposed outside the casing 46 in the internal space of the housing 20. The humidity control mechanism 41 adjusts the humidity of the air that has passed through the suction port 22 and has been sucked into the housing 20. For example, the portable air conditioner 11a includes a humidity sensor (not shown) for detecting the humidity of the air that has passed through the suction port 22 and is sucked into the housing 20, and is based on the detection value of the humidity sensor. Thus, the humidity control mechanism 41 is controlled. For example, the humidity control mechanism 41 adjusts the humidity of the air sucked into the housing 20 so that the relative humidity of the conditioned air blown from the air outlet 21 is within a range of 40% to 70%. In addition, the humidity control mechanism 41 should just have any one function of humidification and dehumidification, and may have the function of both humidification and dehumidification. When the humidity control mechanism 41 has a humidification function, the humidification method is not particularly limited. For example, a steam type or ultrasonic type humidification mechanism can be used. When the humidity control mechanism 41 has a dehumidifying function, the dehumidifying method is not particularly limited. For example, a compressor type or a desiccant type dehumidifying mechanism can be used.

  The portable air conditioner 11a further includes, for example, a filter 45 that separates the internal space of the housing 20. The filter 45 is disposed inside the housing 20 with respect to the suction port 22, and captures dust or foreign matter contained in the air that has passed through the suction port 22 and is sucked into the housing 20. Thereby, it can prevent that dust and a foreign material mix into an air-conditioning wind. For example, the filter 45 is disposed in the internal space of the housing 20 so as to surround the casing 46, the controller 37, and the humidity control mechanism 41. The filter 45 is a filter having a small mesh size such as a filter having a collection efficiency suitable for HEPA or ULPA. In this case, the portable air conditioner 11a can perform air cleaning, and can provide air-conditioned air that has been cleaned. In addition, the higher the collection efficiency of the filter 45, the greater the resistance of the air flow that passes through the filter 45, and the more the power consumption of the portable air conditioner 11a increases. For this reason, when a high degree of air cleaning is unnecessary, the filter 45 may be a filter having a large mesh size such as a filter having a collection efficiency lower than that of HEPA or ULPA.

  The portable air conditioner 11a further includes a filter cleaner 48, for example. The air near the floor 12a with much dust is sucked in from the suction port 22. For this reason, when the portable air conditioner 11a is operated for a predetermined period, the surface of the filter 45 is covered with dust, the flow rate of air passing through the filter 45 is reduced, and the power consumption of the portable air conditioner 11a is increased. there's a possibility that. Therefore, dust on the surface of the filter 45 is removed by the filter cleaner 48. The filter cleaner 48 is, for example, a head 48 a for closely adhering to the filter 45 and sucking dust, a tank 48 b for storing dust sucked by the head 48 a, and moving the head 48 a relative to the filter 45. Including a head moving mechanism (not shown). The timing of cleaning the filter 45 by the filter cleaner 48 is not particularly limited. For example, after the operation of the vapor compression refrigeration cycle apparatus 30 is stopped, or the vapor compression refrigeration cycle apparatus 30 is continuously operated for a predetermined period. Is done when. The tank 48b is detachably attached to the housing 20, for example. The tank 48b is periodically removed, and the dust stored in the tank 48b is discarded. The filter cleaner 48 may further include an automatic dust discharge mechanism (not shown) for automatically discharging stored dust to the outside of the housing 20.

  As shown in FIG. 4, the external heat exchange part 31 is arrange | positioned so that the heat-transfer surface 31a may oppose the indoor floor surface 12a. As shown in FIG. 3, the heat transfer surface 31a occupies most of the bottom surface of the portable air conditioner 11a. When the air conditioning system 10 includes, for example, a heat pump type floor cooling / heating device as the heat source temperature adjustment device 15, the temperature of the floor or the floor surface 12a is adjusted to a predetermined range. In this case, air in the vicinity of the indoor floor or the floor surface 12 a can be used as the heat source 60. The indoor unit 12 of the heat source temperature adjusting device 15 includes, for example, a flooring 12b that forms the floor 12a and a pipe 12c that is disposed below the flooring 12b. The hot or cold water generated by the outdoor unit 13 flows through the pipe 12c, so that the temperature of the floor 12a is adjusted.

  Desirably, the external heat exchange part 31 is arrange | positioned so that the heat-transfer surface 31a may contact the indoor floor surface 12a. In this case, since heat exchange by heat conduction is effectively performed between the floor and the external heat exchange unit 31, the amount of heat received by the external heat exchange unit 31 from the heat source 60 or the external heat exchange unit 31 to the heat source 60. The amount of heat dissipated can be increased.

  As shown in FIG. 4, the portable air conditioner 11a further includes a heat transfer surface moving mechanism 47 for adjusting the distance between the heat transfer surface 31a and the floor surface 12a. As shown in FIG. 2, for example, the controller 37 is connected to the heat transfer surface moving mechanism 47 by wire or wireless, and the controller 37 adjusts the distance between the heat transfer surface 31 a and the floor surface 12 a. The heat transfer surface moving mechanism 47 is controlled. The heat transfer surface moving mechanism 47 includes, for example, a support plate 47a, a rod 47b, and an actuator 47c. The support plate 47a is attached to the external heat exchange unit 31 on the side opposite to the heat transfer surface 31a. One end of the rod 47b is joined to the support plate 47a, and the other end of the rod 47b is accommodated in the actuator 47c. The actuator 47 c is fixed to the bottom wall that forms the bottom surface of the housing 20 inside the housing 20. The rod 47b moves back and forth in the height direction (Z-axis direction) of the portable air conditioner 11a by the action of the actuator 47c. Thereby, the distance between the heat transfer surface 31a and the floor surface 12a is adjusted by the heat transfer surface moving mechanism 47. In this case, a part of the piping that forms the flow path 34a and a part of the piping that forms the flow path 34f have, for example, a bellows part that can be expanded and contracted according to the advance and retreat of the rod 47b.

  Desirably, the heat transfer surface moving mechanism 47 adjusts the distance between the heat transfer surface 31a and the floor surface 12a so that the heat transfer surface 31a contacts the floor surface 12a. This effectively exchanges heat between the floor and the external heat exchanging unit 31 by heat conduction, so the amount of heat received by the external heat exchanging unit 31 from the heat source 60 or the external heat exchanging unit 31 to the heat source 60. The amount of heat dissipated can be increased.

  The heat transfer surface moving mechanism 47 adjusts the distance between the heat transfer surface 31a and the floor surface 12a so that the heat transfer surface 31a is retracted from the floor surface 12a when the portable air conditioner 11a is moved. For example, when the heat transfer surface moving mechanism 47 moves the housing 20, the internal heat exchange unit 33, the external heat exchange unit 31, and the heat transport mechanism 35 by the movement mechanism 42, the heat transfer surface 31 a is the floor surface 12 a. The distance between the heat transfer surface 31a and the floor surface 12a is adjusted so as to retreat. For example, the controller 37 operates the moving mechanism 42 when it is determined that the distance between the portable air conditioner 11a and the occupant is greater than a predetermined distance based on the detection value of the infrared sensor 40. At this time, the controller 37 operates the heat transfer surface moving mechanism 47 so that the heat transfer surface 31 a is retracted from the floor surface 12 a prior to the operation of the moving mechanism 42. For example, the rod 47b is retracted inside the actuator 47c by the actuator 47c. Thereby, it can prevent that the heat-transfer surface 31a becomes the obstruction | occlusion of the movement of the portable air conditioning apparatus 11a. When the movement of the portable air conditioner 11a is completed, the controller 37 operates the heat transfer surface moving mechanism 47 so that the heat transfer surface 31a advances toward the floor surface 12a. Desirably, the controller 37 operates the heat transfer surface moving mechanism 47 so that the heat transfer surface 31a contacts the floor surface 12a. For example, the rod 47b is advanced toward the floor 12a by the actuator 47c.

  The heat transfer surface moving mechanism 47 may be a mechanism that changes the height of the housing 20 to which the external heat exchange unit 31 is fixed. For example, the heat transfer surface moving mechanism 47 may be a mechanism that moves the wheels 42a back and forth in the height direction (Z-axis direction) of the portable air conditioner 11a. Also in this case, the distance between the heat transfer surface 31a and the floor surface 12a can be adjusted by the heat transfer surface moving mechanism 47.

  The portable air conditioner 11 a performs air conditioning of the room A in cooperation with the heat source temperature adjustment device 15, for example. As shown in FIG. 1, the air conditioning system 10 further includes a system controller 17. As shown in FIG. 2, the system controller 17 is connected to the controller 37 of the portable air conditioner 11a by radio, for example. The system controller 17 is connected to a control unit (not shown) of the outdoor unit 13 by wire or wireless, for example. The system controller 17 adjusts the target value of the air conditioning temperature by the portable air conditioner 11a based on the target value of the temperature of the heat source 60 adjusted by the heat source temperature adjusting device 15. Alternatively, the system controller 17 adjusts the target value of the temperature of the heat source 60 that is adjusted by the heat source temperature adjusting device 15 based on the target value of the air conditioning temperature by the portable air conditioner 11a. For example, the system controller 17 sets the target value of the temperature of the heat source 60 adjusted by the heat source temperature adjusting device 15 to be lower during heating than in the case where the portable air conditioner 11a is not operating, Sometimes set higher. In this case, the system controller 17 adjusts the target value of the air conditioning temperature by the portable air conditioner 11 a based on the target value of the temperature of the heat source 60 adjusted by the heat source temperature adjusting device 15. Thereby, useless air conditioning by the heat source temperature adjusting device 15 is suppressed at a position away from the position of the occupant in the room A, and the energy consumption of the air conditioning system 10 can be suppressed. In addition, the portable air conditioner 11a can locally air-condition the space around the occupant in the room A without waiting for the whole room A to be warmed or the whole room A to be cooled. For this reason, desired air conditioning can be realized from the viewpoint of immediate warming or immediate cooling. As a result, the comfort of the occupants in the indoor A can be improved.

  The air conditioning system 10 may include, for example, a plurality of portable air conditioning apparatuses 11a. In this case, when there are a plurality of occupants in the indoor A, the space around each occupant can be locally air conditioned by each portable air conditioner 11a. Moreover, the air conditioning suitable for each occupant can be performed by each portable air conditioner 11a. Thereby, the comfort of each occupant improves. Here, each of the plurality of portable air conditioners 11a may be individually controlled with each occupant. In this case, the comfort of each occupant can be improved advantageously. In addition, the plurality of portable air conditioners 11a may be cooperatively controlled for the occupant located closest. In this case, when these portable air conditioners 11a are cooperatively controlled based on the operating state of another portable air conditioner 11a located in the vicinity of one portable air conditioner 11a, the energy consumption is reduced. Reduced. Further, when the air conditioning system 10 includes a plurality of portable air conditioners 11a, each distance between the portable air conditioners 11a is equal to or greater than a predetermined value, for example, based on the detection value in the infrared sensor 40, The movement mechanism 42 of the portable air conditioner 11a may be controlled. Thereby, it can prevent that the several portable air conditioner 11a interferes with each other.

(Modification)
The air conditioning system 10 and the portable air conditioning apparatus 11a can be changed from various viewpoints. For example, at least a part of the heat transfer surface 31 a may be provided with a through hole that penetrates the external heat exchange unit 31 and connects to the internal space of the housing 20. In this case, when air is sucked from the through hole, air existing on the floor 12a around the portable air conditioner 11a gathers toward the heat transfer surface 31a.

  The portable air conditioner 11a may further include a handle that can be held by a occupant instead of the moving mechanism 42 or together with the moving mechanism 42. Thereby, the occupant can lift the portable air conditioner 11a using the handle and move the portable air conditioner 11a to a desired position.

Second Embodiment
A portable air conditioner 11b according to a second embodiment of the present disclosure will be described. The portable air conditioner 11b is configured in the same manner as the portable air conditioner 11a unless otherwise described. Of the components of the portable air conditioner 11b, the same or corresponding components as those of the portable air conditioner 11a are assigned the same reference numerals, and detailed description thereof is omitted. The description regarding the portable air conditioner 11a also applies to the portable air conditioner 11b unless there is a technical contradiction.

  As shown in FIG. 5, in the portable air conditioner 11 b, the heat transport mechanism 35 includes a Peltier element 50 disposed between the internal heat exchange unit 33 and the external heat exchange unit 31. The Peltier element 50 is a semiconductor element that utilizes the Peltier effect that heat is transferred from one metal to the other when an electric current is passed through a joint between two kinds of metals. The Peltier device 50 includes, for example, a p-type semiconductor 51a, an n-type semiconductor 51b, a first electrode 53a, a second electrode 53b, a third electrode 53c, a lower substrate 55, and an upper substrate 56. The lower substrate 55 is, for example, a ceramic substrate. One main surface of the lower substrate 55 is joined to the external heat exchange unit 31 on the side opposite to the heat transfer surface 31a. On the other main surface of the lower substrate 55, the first electrode 53a and the second electrode 53b are arranged apart from each other. The first electrode 53a and the second electrode 53b are each made of a metal such as copper. The first electrode 53a is bonded to the p-type semiconductor 51a on the side opposite to the lower substrate 55. The second electrode 53b is bonded to the n-type semiconductor 51b on the side opposite to the lower substrate 55. The end of the p-type semiconductor 51a opposite to the first electrode 53a and the end of the n-type semiconductor 51b opposite to the second electrode 53b are connected by a third electrode 53c. The third electrode 53c is made of a metal such as copper. The third electrode 53c is bonded to the upper substrate 56 on the opposite side to the p-type semiconductor 51a and the n-type semiconductor 51b. The upper substrate 56 is, for example, a ceramic substrate. The upper substrate 56 is joined to the internal heat exchange part 33 on the side opposite to the third electrode 53c. Note that the numbers of the p-type semiconductor 51a, the n-type semiconductor 51b, the first electrode 53a, the second electrode 53b, and the third electrode 53c are not particularly limited as long as they are joined as described above.

  The portable air conditioner 11b further includes a current supply unit 52, for example. The current supply unit 52 is electrically connected to the first electrode 53a by an electric wiring 57a. The current supply unit 52 is electrically connected to the second electrode 53b by an electric wiring 57b. The current supply unit 52 selectively supplies currents in opposite directions to the Peltier element 50. The controller 37 is connected to the current supply unit 52 wirelessly or by wire, and adjusts the direction and magnitude of the current supplied from the power supply unit 52 to the Peltier element 50.

  When the portable air conditioner 11b performs the heating operation, a current is supplied from the current supply unit 52 to the Peltier element 50 so that the potential of the first electrode 53a is higher than the potential of the second electrode 53b. Thereby, the heat received from the heat source 60 by the external heat exchanging unit 31 is transported to the internal heat exchanging unit 33 by the Peltier effect, and the internal heat exchanging unit 33 heats the air sucked into the housing 20 to perform air conditioning. Wind is generated. On the other hand, when the portable air conditioner 11b performs a cooling operation, a current is supplied from the current supply unit 52 to the Peltier element 50 so that the potential of the first electrode 53a is lower than the potential of the second electrode 53b. Thereby, the external heat exchanging part 31 dissipates the heat transported from the internal heat exchanging part 33 to the heat source 60 by the Peltier effect. Thereby, the internal heat exchanging unit 33 cools the air sucked into the housing 20 and generates conditioned air. For example, the controller 37 adjusts the magnitude of the current to be supplied to the Peltier element 50 by the current supply unit 52 based on the detected value (detected temperature) of the intake air temperature sensor 39. Thereby, the movement amount of the heat transported by the Peltier element 50 can be adjusted. For example, when the portable air conditioner 11b performs the heating operation, when the detected value (detected temperature) of the intake air temperature sensor 39 is relatively low, the controller 37 determines the current to be supplied to the Peltier element 50. The current supply unit 52 is controlled so that the size becomes relatively large. In the case where the portable air conditioner 11b performs the cooling operation, when the detected value (detected temperature) of the intake air temperature sensor 39 is relatively high, the controller 37 has a magnitude of the current to be supplied to the Peltier element 50. Is controlled to be relatively large.

  In the portable air conditioner 11b, the external heat exchange unit 31 is configured by a plate made of metal such as copper. The internal heat exchanging section 33 may have a structure in which fins extending upward are joined to a plate made of a metal such as copper. The contact area between the air sucked into the housing 20 and the internal heat exchanging portion 33 is increased by the fins. Thereby, more heat can be exchanged between the air sucked into the housing 20 and the internal heat exchanging unit 33.

  In the portable air conditioner 11b, the Peltier element 50 is supported by the heat transfer surface moving mechanism 47. For example, the lower substrate 55 is supported by the heat transfer surface moving mechanism 47. The heat transfer surface moving mechanism 47 includes a rod 47d and an actuator 47e. One end of the rod 47 d is engaged with the peripheral edge of the lower substrate 55. The other end of the rod 47d is accommodated in the actuator 47e. The actuator 47 moves the rod 47d back and forth in the height direction (Z-axis direction) of the portable air conditioner 11b. Thereby, the heat transfer surface moving mechanism 47 adjusts the distance between the heat transfer surface 31a and the floor surface 12a. The heat transfer surface moving mechanism 47 may support members of the Peltier element 50 other than the lower substrate 55.

(Modification)
The portable air conditioner 11b can be changed from various viewpoints. For example, the portable air conditioner 11b uses the vapor compression refrigeration cycle 30 together with the internal heat exchange unit 31 and the external heat exchange unit 33 described in the first embodiment as the heat transport mechanism 35 in addition to the Peltier element 50. You may further provide the mechanism to comprise.

(Other)
Each of the controller 37 and the system controller 17 only needs to have a control function, and each includes an arithmetic processing unit (not shown) and a storage unit (not shown) for storing a control program. The arithmetic processing unit is exemplified by an MPU (microprocessor unit) or a CPU (central processing unit), and the storage unit is exemplified by a memory. The controller may be configured by a single controller that performs centralized control, or may be configured by a plurality of controllers that perform distributed control in cooperation with each other.

  The technology disclosed in this specification can be suitably used for an air conditioning system that performs operations such as cooling, heating, dehumidification, or humidification.
