Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in order for the agent to function effectively, it is necessary to set the airborne concentration, which is the concentration of the agent in the target space, to an appropriate concentration. The volatilization amount of the agent varies under the influence of various air conditions such as temperature, humidity, pressure, and air volume. The air conditions are particularly prone to fluctuation in places such as the interior of houses where people reside. In places where air conditions fluctuate, it is difficult to keep the airborne concentration of the agent constant.

[0005] An object of the present disclosure is to suppress fluctuations in the airborne concentration of an agent.

Means for Solving the Problems

[0006] A first aspect is directed to a dispersal device. The dispersal device includes a volatile agent (31) that acts on insects (I) in a target space (S), heat sources (33, 233) that heat or cool the agent (31), and controllers (120, 220, 320) that control the heat sources (33, 233) based on information related to the air state of the blast air directed to the agent (31).

[0007] In the first embodiment, the agent (31) is heated or cooled based on the air conditions of the air supplied to the agent (31). By heating or cooling the agent (31), the amount of agent (31) released is adjusted. The release device adjusts the amount of agent (31) released based on the air conditions of the air supplied to the agent (31), thereby suppressing fluctuations in the airborne concentration.

[0008] In a second embodiment, in the first embodiment, the heat source (33,233) has a cooling function for cooling the agent (31).

[0009] In the second embodiment, the amount of volatilization from the agent (31) is suppressed by cooling the agent (31). The dispersion device can suppress fluctuations in the airborne concentration while preventing excessive volatilization of the agent (31).

[0010] In a third embodiment, in the second embodiment, the heat source (33,233) has a heating function for heating the agent (31) in addition to the cooling function.

[0011] In the third embodiment, the dispersion device can precisely control the amount of volatilization and suppress fluctuations in the airborne concentration.

[0012] In a fourth embodiment, in the third embodiment, the heat source (33,233) includes a Peltier element (34).

[0013] In the fourth embodiment, the Peltier element (34) is an element that has both a cooling function and a heating function. The dissipation device can cool and heat the agent (31) with a simple configuration and can suppress fluctuations in the air concentration.

[0014] The fifth aspect is that in any one of the first to fourth aspects, the information relating to the air conditions includes temperature, humidity, pressure, or airflow.

[0015] In the fifth embodiment, the dispersal device adjusts the temperature of the agent (31) based on factors that can vary the amount of volatilization. The dispersal device can precisely control the amount of volatilization and suppress fluctuations in the airborne concentration.

[0016] In the sixth aspect, in the fifth aspect, the controller (120, 220, 320) controls the heat source (33, 233) to cool the agent (31) when the temperature of the blown air rises.

[0017] When the temperature of the blown air rises, the agent (31) becomes more volatile. In the sixth embodiment, the dispersion device can suppress fluctuations in the concentration in the air by cooling the agent (31) when the temperature of the blown air rises.

[0018] In the seventh aspect, in the fifth aspect, the controller (120, 220, 320) controls the heat source (33, 233) to cool the agent (31) when the humidity of the blown air decreases.

[0019] When the humidity of the blown air decreases, the agent (31) becomes more volatile. In the seventh embodiment, the dispersion device can suppress fluctuations in the concentration in the air by cooling the agent (31) when the humidity of the blown air decreases.

[0020] The eighth aspect is, in the fifth aspect, the controller (120, 220, 320) controls the heat source (33, 233) to cool the agent (31) when the pressure of the blown air decreases.

[0021] When the pressure of the blown air decreases, the agent (31) becomes more volatile. In the eighth embodiment, the dispersion device can suppress fluctuations in the concentration in the air by cooling the agent (31) when the pressure of the blown air decreases.

[0022] The ninth aspect is, in the fifth aspect, the controller (120, 220, 320) controls the heat source (33, 233) to cool the agent (31) when the airflow rate of the blown air increases. When the air volume of the supply air increases, the volatilized agent (31) easily flows into the target space (S). In the ninth aspect, the dissipating device can suppress the fluctuation of the airborne concentration by cooling the agent (31) when the air volume of the supply air increases.

[0023] In a tenth aspect based on the fifth aspect, the controller (120, 220, 320) controls the heat source (33, 233) based on the volatilization amount of the agent (31) calculated based on the information related to the air state.

[0024] In the tenth aspect, the dissipating device can accurately estimate the level of the airborne concentration by using the volatilization amount calculated based on the information related to the air state. The dissipating device can accurately suppress the fluctuation of the airborne concentration.

[0025] In an eleventh aspect based on any one of the first to tenth aspects, the information related to the air state includes information related to the airborne concentration of the agent (31) in the target space (S).

[0026] In the eleventh aspect, the dissipating device can finely suppress the fluctuation of the airborne concentration by directly considering the information related to the airborne concentration.

[0027] In a twelfth aspect based on the twelfth aspect, the information related to the airborne concentration is an output result of a VOC sensor (365, 366) that detects the VOC concentration in the target space (S).

[0028] In the twelfth aspect, the level of the airborne concentration can be accurately estimated by using the VOC sensor (365, 366). The dissipating device can accurately suppress the fluctuation of the airborne concentration.

[0029] A thirteenth aspect is directed to an air conditioning apparatus. The air conditioning apparatus includes: the dissipating device according to any one of the first to twelfth aspects; and an air conditioning unit (10) that adjusts the temperature or humidity of air, wherein the air conditioning unit (10) and the heat source (33, 233) are separate bodies.

[0030] According to the 13th embodiment, even if the temperature and humidity of the air are changed by the air conditioning unit (10), the dispersion device can suppress fluctuations in the amount of volatilization of the agent (31) by heating or cooling the agent (31) with the heat source (33).

[0031] In the 14th embodiment, the air conditioning unit (10) comprises a housing (21) located within the target space (S), and the radiating device is located in an air conditioning passage (25) within the housing (21).

[0032] According to the 14th embodiment, since the dispersal device is located in the air conditioning passage (25), the air supplied to the agent (31) is the air from the air conditioning passage (25). Therefore, the amount of agent volatilized is more influenced by the air condition of the air conditioning passage (25) than by the air condition of the target space (S). By controlling the heat sources (33, 233) based on the air condition of the supplied air rather than the air condition of the target space (S), the dispersal device can accurately suppress fluctuations in the amount of agent (31) volatilized.

[0033] The 15th embodiment relates to a dispersion system. The dispersion system comprises a volatile agent (31) that acts on insects (I) in a target space (S), an acquisition unit (61, 62, 63, 64, 365, 366) that acquires information on the air condition of the air blown to the agent (31), a heat source (33, 233) that heats or cools the agent (31), and a controller (120, 220, 320) that controls the heat source (33, 233) based on the information on the air condition acquired by the acquisition unit (61, 62, 63, 64, 365, 366).

[0034] The sixteenth aspect relates to a dispersion method. The dispersion method comprises a first step of acquiring information regarding the air conditions of the air blown onto a volatile agent (31) that acts on insects (I) in a target space (S), and a second step of heating or cooling the agent (31) based on the air conditions of the air blown onto the agent (31) using a heat source (33,233) that adjusts the temperature of the agent (31).

[0036] The embodiments of this disclosure will be described in detail below with reference to the drawings. However, this disclosure is not limited to the embodiments shown below, and various modifications are possible without departing from the technical idea of ​​this disclosure. Since the drawings are for conceptual illustration of this disclosure, dimensions, ratios, or numbers may be exaggerated or simplified as necessary for ease of understanding.

[0037] (1) Dispersion system Figure 1 schematically shows the emission system (1) according to this embodiment. The emission system (1) is a system for emitting an inhibitor into the target space (S) that inhibits the activity of insects (I) present in the target space (S) and insects that invade from the outside. The emission system (1) creates an environment in the target space (S) that is unsuitable for insects (I). This makes it possible to create an environment in the target space (S) in which the number of insects (I) is reduced.

[0038] As shown in Figure 1, the target space (S) is an indoor space where people stay, such as a bedroom, living room, kitchen, or office in a house. The insects (I) targeted for inhibition by the emission system (1) are, for example, cockroaches, mites, and mosquitoes. These insects (I) are organisms that occur relatively frequently in target spaces (S) where people live.

[0039] The emission system (1) of this embodiment comprises an air conditioner (AC) equipped with an emission device (30) and a communication terminal (150).

[0040] (1-1) Air conditioning system The air conditioning system (AC) includes an air conditioning unit (10) that adjusts the temperature and humidity of the air in a target space (S). The air conditioning unit (10) has an outdoor unit (11) installed outside and an indoor unit (20) installed in the target space (S). The outdoor unit (11) and the indoor unit (20) are connected by refrigerant piping (12). The air conditioning unit (10) has a temperature control function. Specifically, the air conditioning unit (10) performs cooling operation to cool the air in the target space (S) and heating operation to heat the air in the target space (S).

[0041] As shown in Figure 1, the outdoor unit (11) is installed in the outdoor space, which is outside the target space (S). The outdoor unit (11) comprises an outdoor casing (13) and an outdoor element housed in the outdoor casing (13). The outdoor element includes a compressor, an outdoor heat exchanger, an expansion valve, a four-way switching valve, and an outdoor fan.

[0042] The indoor unit (20) is wall-mounted. Specifically, the indoor unit (20) is installed on the upper part of the interior wall of the building. The indoor unit (20) has an indoor casing (21), an indoor heat exchanger (22), an indoor fan (23), and a flap (24).

[0043] The indoor casing (21) is formed in the shape of a horizontally elongated hollow box. The indoor casing (21) has a roughly rectangular cross-section. Intake ports (21a) are formed on the front and top surfaces of the indoor casing (21). An outlet port (21b) is formed on the lower front side of the indoor casing (21). Inside the indoor casing (21), an air conditioning passage (25) is formed from the intake port (21a) to the outlet port (21b).

[0044] The indoor heat exchanger (22) is located in the air conditioning passage (25). The indoor heat exchanger (22) functions as an evaporator during cooling operation and as a condenser (radiator) during heating operation. The indoor fan (23) is located downstream of the indoor heat exchanger (22) in the air conditioning passage (25). The indoor fan (23) is a cross-flow fan. The indoor fan (23) is a variable-volume fan with a variable motor speed. The indoor fan (23) generates airflow in the target space (S). The indoor fan (23) generates a flow that circulates the air throughout the entire target space (S). Specifically, when the indoor fan (23) is operating, the air blown out from the outlet (21b) of the indoor unit (20) flows along the floor, wall, and ceiling surfaces facing the target space (S) in order, before returning to the intake (21a).

[0045] The flap (24) is provided at the air outlet (21b) of the indoor unit (20). The flap (24) extends substantially horizontally along the air outlet (21b). The flap (24) is rotationally driven by a motor (not shown). The flap (24) changes the direction of the air blown out from the air outlet (21b). By changing the position of the flap (24), the air can be directed towards, for example, the floor, wall, ceiling, or specific furniture facing the target space (S).

[0046] The indoor unit (20) has multiple sensors. Specifically, the indoor unit (20) has a temperature sensor (61), a humidity sensor (62), a pressure sensor (63), and an airflow sensor (64). The temperature sensor (61) detects the temperature of the intake air drawn into the intake port (21a). The temperature sensor (61) may be placed in the target space (S). The humidity sensor (62) detects the relative humidity of the intake air drawn into the intake port (21a). The humidity sensor (62) may be placed in the target space (S). The pressure sensor (63) detects the air pressure inside the indoor unit (20). The airflow sensor (64) detects the airflow of the air released from the indoor fan (23) and flowing through the air conditioning passage (25).

[0047] (1-2) Dispersion device The dispersing device (30) disperses the inhibitor (31) into the target space (S). The dispersing device (30) is housed in the indoor unit (20). The dispersing device (30) is attached to the inner wall of the indoor casing (21) of the indoor unit (20). The dispersing device (30) is positioned, for example, near the air outlet (21b) in the air conditioning passage (25) of the indoor unit (20).

[0048] As shown in Figure 2, the emission device (30) comprises an inhibitor (31), a casing (32), a heat source (33), and an emission control unit (120).

[0049] The inhibitor (31) is solid and volatile. The volatile component (G), which is the part that volatilizes from the inhibitor (31), is released into the target space (S) by being carried by the air flowing through the air conditioning passage (25). The inhibitor (31) is a substance that reduces the sensitivity of the olfactory and tactile functions of the insect (I) or inhibits the reproductive capacity and proliferation of the insect (I). The inhibitor (31) is not particularly limited, but for example, it is a phenolic agent.

[0050] The casing (32) houses the inhibitor (31) and the Peltier element (34). The casing (32) is shaped like a rectangular box. The casing (32) has a first wall (32a), a second wall (32b), a third wall (32c), and a fourth wall (32d). The first wall (32a) and the third wall (32c) face the direction of airflow. The second wall (32b) and the fourth wall (32d) face the direction perpendicular to the direction of airflow. The first wall (32a), the second wall (32b), and the third wall (32c) have a plurality of openings (32e). Air flowing into the casing (32) from the opening (32e) of the first wall (32a) is released to the outside of the casing (32) from the openings (32e) of the second wall (32b) and the third wall (32c), along with volatile components (G). The fourth wall (32d) has no opening. Although not shown in the illustration, walls also exist on the far side and near side of the page.

[0051] The heat source (33) heats and cools the inhibitor (31). The heat source (33) is separate from the indoor heat exchanger (22) of the air conditioning unit (10). The heat source (33) includes a Peltier element (34), a first heat conduction unit (35), a second heat conduction unit (36), and a power supply (37).

[0052] The Peltier element (34) includes a plurality of P-type and N-type semiconductors arranged alternately. Adjacent P-type and N-type semiconductors are connected by a metal junction (34a). Adjacent junctions (34a) are in contact with each other a first heat conduction section (35) and a second heat conduction section (36). The first heat conduction section (35) is thermally connected to an inhibitor (31). The second heat conduction section (36) has a plurality of fins (36a). The Peltier element (34) conducts heat to the first heat conduction section (35) and the second heat conduction section (36) through the junction (34a). The fins (36a) penetrate the fourth wall (32d) of the casing (32) and are exposed to the outside of the casing (32). The Peltier element (34) cools when current flows from the N-type semiconductor to the P-type semiconductor, and heats when no current flows in the reverse direction. When the second heat conduction part (36) is on the cooling side, the fins (36a) absorb heat from the surrounding air. When the second heat conduction part (36) is on the heating side, the fins (36a) dissipate heat to the surrounding air. The semiconductor and junction (34a) constituting the Peltier element (34) are electrically insulated from the first heat conduction part (35) and the second heat conduction part (36).

[0053] The power supply (37) is electrically connected to the Peltier element (34). The power supply (37) supplies a direct current to the Peltier element (34). The power supply (37) is a power supply that can switch the direction of the current between the forward direction (direction of arrow D1) and the reverse direction (direction of arrow D2). When the direction of the current from the power supply (37) is forward, the first heat conduction part (35) of the Peltier element (34) becomes the cooling side and the second heat conduction part (36) becomes the heating side. On the other hand, when the direction of the current from the power supply (37) is reverse, the first heat conduction part (35) of the Peltier element (34) becomes the heating side and the second heat conduction part (36) becomes the cooling side.

[0054] The heat dissipation control unit (120) controls the heat source (33). The heat dissipation control unit (120) controls the direction and magnitude of the current from the power supply (37). The heat dissipation control unit (120) is an example of a controller. Details of the control by the heat dissipation control unit (120) will be described later.

[0055] (1-3) Controllers and their peripheral elements As shown in Figure 3, the radiation system (1) has a controller (100). The controller (100) includes a processor such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit), electrical circuits, and electronic circuits. The controller (100) includes a memory device (specifically semiconductor memory) that stores software for operating the processor, etc. The controller (100) may consist of one physically independent element or of two or more physically separated elements.

[0056] The controller (100) in this embodiment includes an air conditioning control unit (110) that controls the air conditioning unit (10) and a emission control unit (120) that controls the emission device (30). The air conditioning control unit (110) is not an essential component of the controller (100) in the emission system (1).

[0057] The air conditioning control unit (110) includes an indoor control unit (111) and an outdoor control unit (112). The indoor control unit (111) is installed in the indoor unit (20). The outdoor control unit (112) is installed in the outdoor unit (11). The indoor control unit (111) and the outdoor control unit (112) are connected to each other via a communication line (not shown). The air conditioning control unit (110) controls the compressor, outdoor fan, four-way switching valve, expansion valve, indoor fan (23), etc. The air conditioning control unit (110) controls the ON / OFF switching of the indoor fan (23), and controls the rotation speed of the indoor fan (23), in other words, the airflow rate of the discharged air or intake air of the air conditioning unit (10). The air conditioning control unit (110) adjusts the angle of the flap (24).

[0058] The air conditioning control unit (110) is connected to the temperature sensor (61), humidity sensor (62), pressure sensor (63), and airflow sensor (64) via a wired or wireless communication line. The air conditioning control unit (110) acquires information about the air conditions from the temperature sensor (61), humidity sensor (62), pressure sensor (63), and airflow sensor (64).

[0059] The emission control unit (120) controls the emission operation of the emission device (30) in which it emits the inhibitor (31) into the target space (S). Specifically, the emission control unit (120) controls the amount of volatilization of the inhibitor (31) into the target space (S) by heating or cooling the inhibitor (31) with a heat source (33). The emission control unit (120) adjusts the amount of heat supplied to the inhibitor (31) or the amount of heat released from the inhibitor (31) by adjusting the direction and magnitude of the DC current flowing from the power supply (37) to the Peltier element (34). The emission control unit (120) controls the airborne concentration of the inhibitor (31) in the target space (S) by controlling the amount of volatilization of the inhibitor (31). In this specification, "volatilization amount" refers to the mass of the inhibitor (31) volatilized per unit time.

[0060] The emission control unit (120) has a memory unit (121). The memory unit (121) stores information about the target space (S), such as spatial volume, characteristic formulas showing the relationship between information about the air condition of the air supplied to the inhibitor (31) and the amount of volatilization of the inhibitor (31), and a program for controlling the power supply (37).

[0061] As shown in Figure 3, the radiation system (1) has a router (130) which is a communication interface. The router (130) is connected to a server device (140) on the cloud via a network (N). The air conditioning control unit (110) is connected to the router (130) via a first wireless or wired communication line (W1), and the radiation control unit (120) is connected to the router (130) via a second wireless or wired communication line (W2). In this way, the air conditioning control unit (110) and the radiation control unit (120) are configured to receive a common signal. Specifically, the radiation control unit (120) can obtain information about the air condition acquired by the air conditioning control unit (110) via the router (130) and the server device (140).

[0062] The radiation system (1) of this embodiment has a communication terminal (150). The communication terminal (150) of this embodiment is a smartphone. The communication terminal (150) includes a microcomputer and a memory device. The memory device stores software for operating the microcomputer. The communication terminal (150) is connected to a server device (140) via a network (N).

[0063] The communication terminal (150) is a terminal for the user to operate the air conditioning unit (AC). Operation of the air conditioning unit (10) includes starting and stopping the operation of the air conditioning unit (10), switching the operating mode of the air conditioning unit (10), setting the target temperature of the air conditioning unit (10), and setting the target airflow of the indoor fan (23). Operation of the radiating device (30) includes starting and stopping the radiating operation of the radiating device (30).

[0064] The air conditioning system (AC) has a remote controller (115) for operating the air conditioning unit (10), separate from the communication terminal (150). The user can operate the air conditioning unit (10) in the same way as the communication terminal (150) by operating the remote controller (115).

[0065] (2) Operating The operation of the emission system (1) will be described below.

[0066] (2-1) Operation of the air conditioning unit (10) In cooling operation, the air conditioning unit (10) performs a refrigeration cycle in which the outdoor heat exchanger functions as a radiator (condenser) and the indoor heat exchanger (22) functions as an evaporator. When the indoor fan (23) is operated, air from the target space (S) flows into the air conditioning passage (25) from the intake (21a). The air in the air conditioning passage (25) is cooled by the indoor heat exchanger (22) and then supplied to the target space (S) from the outlet (21b).

[0067] In heating operation, the air conditioning unit (10) performs a refrigeration cycle in which the indoor heat exchanger (22) functions as a radiator (condenser) and the outdoor heat exchanger functions as an evaporator. When the indoor fan (23) is operated, air from the target space (S) flows into the air conditioning passage (25) from the intake (21a). The air in the air conditioning passage (25) is heated by the indoor heat exchanger (22) and then supplied to the target space (S) from the outlet (21b).

[0068] (2-2) Operation of the dispersion device (30) The dispersing device (30) disperses the inhibitor (31) into the target space (S) during its dispersal operation. Specifically, the dispersing device (30) controls the amount of volatilization of the inhibitor (31) so that the airborne concentration of the inhibitor (31) in the target space (S) remains constant at a target concentration. The target concentration is a concentration that is effective against insects (I). The target concentration may be different for each type of insect (I). Note that the dispersal operation of the dispersing device (30) does not need to be performed simultaneously with the cooling and heating operation of the air conditioning unit (10). For example, when performing the dispersal operation, the air conditioning control unit (110) may operate only the indoor fan (23) without operating the outdoor unit (11). This allows the dispersal operation to be performed without cooling or heating operation.

[0069] The amount of volatilization of the inhibitor (31) is affected by the air quality of the air supplied to the inhibitor (31). In this embodiment, information regarding the air quality includes temperature, humidity, pressure, and airflow rate. The air quality of the supplied air is affected not only by changes in external temperature and humidity, but also by the operating state of the air conditioning unit (10). For example, in summer, if the outdoor unit (11) is stopped, the temperature of the air supplied to the inhibitor (31) will be high, similar to the external temperature. However, when the outdoor unit (11) is activated and cooling operation begins, cooled air flows through the air conditioning passage (25), so the temperature of the air supplied to the inhibitor (31) decreases. In winter, conversely, when the air conditioning unit (10) starts heating operation, warmed air flows through the air conditioning passage (25), so the temperature of the air supplied to the inhibitor (31) increases.

[0070] Here, we will explain the relationship between various pieces of information regarding air conditions and the amount of volatilization of the inhibitor (31). Regarding temperature, the higher the temperature, the greater the volatilization, and the lower the temperature, the greater the volatilization. Regarding humidity, the higher the humidity, the greater the volatilization, and the lower the humidity, the greater the volatilization. Regarding pressure, the higher the pressure, the greater the volatilization, and the lower the pressure, the greater the volatilization. Regarding airflow, the higher the airflow, the greater the volatilization, and the lower the airflow, the greater the volatilization.

[0071] In this embodiment, the emission control unit (120) heats or cools the inhibitor (31) based on the air condition of the air supplied to the inhibitor (31). Of the information regarding the air condition, the temperature is the output result of the temperature sensor (61), and the humidity is the output of the humidity sensor (62). The temperature sensor (61) and humidity sensor (62) detect the temperature and humidity of the intake air of the indoor unit (20), but since the temperature and humidity of the intake air affect the temperature and humidity of the supplied air, this can be said to be information regarding the air condition of the air supplied to the inhibitor (31). Of the information regarding the air condition, the pressure is the output result of the pressure sensor (63), and the airflow is the output result of the airflow sensor (64).

[0072] As shown in Figure 4, the memory unit (121) of the emission control unit (120) stores a characteristic formula that shows the relationship between each piece of information about the air condition and the amount of volatilization of the inhibitor (31). The emission control unit (120) calculates the target temperature, which is the temperature at which the airborne concentration of the pesticide reaches the target concentration, from the characteristic formula and the spatial volume of the target space (S). For example, the emission control unit (120) calculates the temperature at which the target concentration is reached, using the temperature in the characteristic formula as the temperature of the pesticide. The temperature in the characteristic formula corresponds to the surface temperature of the inhibitor (31) when the heat source (33) is not operating, that is, when no current is supplied to the Peltier element (34). Therefore, the target temperature calculated as described above corresponds to the target surface temperature of the inhibitor (31). Since the amount of volatilization of the inhibitor (31) is particularly affected by the surface temperature of the inhibitor (31), it is acceptable to consider the target surface temperature of the inhibitor (31) as corresponding to the target temperature.

[0073] The dissipation control unit (120) controls the heat source (33) to bring the temperature of the inhibitor (31) to a calculated target temperature. Specifically, when the target temperature is lower than the temperature of the inhibitor (31) before the heat source (33) is activated, the dissipation control unit (120) controls the power supply (37) so that a positive current flows through the Peltier element (34). As a result, the first heat conduction unit (35) becomes the cooling side, and the inhibitor (31) is cooled toward the target temperature. On the other hand, when the target temperature is higher than the temperature of the inhibitor (31) before the heat source (33) is activated, the dissipation control unit (120) controls the power supply (37) so that a reverse current flows through the Peltier element (34). As a result, the first heat conduction unit (35) becomes the heating side, and the inhibitor (31) is heated toward the target temperature. The amount of volatilization of the inhibitor (31) is particularly affected by the surface temperature of the inhibitor (31). Before the heat source (33) is activated, the surface temperature of the inhibitor (31) is equal to the temperature of the air conditioning passage (25). Therefore, the "temperature of the inhibitor (31) before the heat source (33) is activated" can be the temperature obtained by the temperature sensor (61).

[0074] The heat dissipation control unit (120) sets the current value based on the temperature difference between the inhibitor (31) before activating the heat source (33) and the target temperature. Specifically, the heat dissipation control unit (120) sets a larger current value the greater the temperature difference.

[0075] Figure 5 is a flowchart showing the operation of the dissipation device (30). When the dissipation system (1) starts operation, the air conditioning control unit (110) turns on the indoor fan (23). After the indoor fan (23) is turned on, as shown in Figure 5, in step ST101, the dissipation control unit (120) acquires information about the air condition of the air supplied to the inhibitor (31) from each sensor (61, 62, 63, 64). After acquiring the information about the air condition, in step ST102, the dissipation control unit (120) calculates the target temperature of the inhibitor (31).

[0076] The emission control unit (120) determines in the next step ST103 whether or not it is necessary to cool the inhibitor (31). The emission control unit (120) makes this determination by comparing the detection result of the temperature sensor (61) with the target temperature. For example, the emission control unit (120) determines that it is necessary to cool the inhibitor (31) if the target temperature is 0.5°C or more lower than the temperature of the inhibitor (31) before the heat source (33) is activated. If the emission control unit (120) determines that it is necessary to cool the inhibitor (31), it proceeds to step ST105. If the emission control unit (120) determines that it is not necessary to cool the inhibitor (31), it proceeds to step ST104.

[0077] In step ST104, the emission control unit (120) determines whether or not it is necessary to heat the inhibitor (31). The emission control unit (120) makes this determination by comparing the detection result of the temperature sensor (61) with the target temperature. For example, the emission control unit (120) determines that it is necessary to heat the inhibitor (31) if the target temperature is 0.5°C or more higher than the temperature of the inhibitor (31) before the heat source (33) is activated. If the emission control unit (120) determines that it is necessary to heat the inhibitor (31), it proceeds to step ST106. If the emission control unit (120) determines that it is not necessary to heat the inhibitor (31), it returns.

[0078] In step ST105, the dissipation control unit (120) controls the heat source (33) to cool the inhibitor (31). The dissipation control unit (120) controls the power supply (37) so that a positive current flows through the Peltier element (34). The dissipation control unit (120) sets the current value based on the difference between the temperature of the inhibitor (31) before activating the heat source (33) and the target temperature, and supplies the Peltier element (34) with the set current value. After step ST105, the system returns to the previous state.

[0079] In step ST106, the radiation control unit (120) controls the heat source (33) to heat the inhibitor (31). The radiation control unit (120) controls the power supply (37) so that a reverse current flows through the Peltier element (34). The radiation control unit (120) sets the current value based on the difference between the temperature of the inhibitor (31) before activating the heat source (33) and the target temperature, and supplies the Peltier element (34) with the set current value. After step ST106, the system returns to the previous state.

[0080] (3) Effects of the embodiment The emission device (30) of the emission system (1) according to this embodiment includes a emission control unit (120) that controls a heat source (33) for heating or cooling the inhibitor (31) based on information regarding the air conditions of the air supplied to the inhibitor (31). The amount of volatilization of the inhibitor (31) is affected by the air conditions of the air supplied to the inhibitor (31). When the air conditions are such that the amount of volatilization of the inhibitor (31) is high, the emission control unit (120) controls the heat source (33) to cool the inhibitor (31). On the other hand, when the air conditions are such that the amount of volatilization of the inhibitor (31) is low, the emission control unit (120) controls the heat source (33) to heat the inhibitor (31). As a result, fluctuations in the amount of volatilization of the inhibitor (31) are suppressed, and the emission device (30) can suppress fluctuations in the airborne concentration of the inhibitor (31).

[0081] In the dissipation device (30) of the dissipation system (1) according to this embodiment, the heat source (33) in particular has the function of cooling the inhibitor (31). This makes it possible to suppress excessive volatilization of the inhibitor (31), thereby extending the service life of the dissipation device (30).

[0082] In this embodiment, the emission control unit (120) calculates a target temperature for the inhibitor (31) so that the airborne concentration of the inhibitor (31) reaches the target concentration. The emission control unit (120) controls the heat source (33) so that the temperature of the inhibitor (31) reaches the target temperature. As a result, fluctuations in the airborne concentration of the inhibitor (31) relative to the target concentration can be suppressed, and the emission device (30) can enhance the inhibitory effect on insects (I) by the inhibitor (31).

[0083] In this embodiment, the heat source (33) has a Peltier element (34), which heats and cools the inhibitor (31). Heating and cooling of the inhibitor (31) can be performed with a simple configuration, and fluctuations in the air concentration can be suppressed.

[0084] In this embodiment, information regarding the air conditions includes the temperature, humidity, and airflow rate of the air supplied to the inhibitor (31). This information affects the amount of volatilization of the inhibitor (31). Therefore, the dispersal device (30) can precisely control the amount of volatilization of the inhibitor (31) and suppress fluctuations in the air concentration.

[0085] In particular, in this embodiment, information regarding the air condition is the output results of the temperature sensor (61), humidity sensor (62), pressure sensor (63), and airflow sensor (64). By using the sensor values, the air condition of the supplied air can be determined with high accuracy, and the amount of volatilization of the inhibitor (31) can be precisely controlled. Therefore, the dispersal device (30) can suppress fluctuations in the air concentration.

[0086] In this embodiment, the dispersal device (30) is located in the air conditioning passage (25) of the indoor casing (21) of the air conditioning unit (10). This allows the airflow from the indoor fan (23) of the indoor unit (20) to be used to disperse the inhibitor (31), eliminating the need for a separate blower for the dispersal device (30). Furthermore, the amount of inhibitor (31) dispersed is influenced more by the air quality of the air blown through the air conditioning passage (25) than by the air quality of the target space (S). As in this embodiment, by heating or cooling the inhibitor (31) based on the air quality of the air blown to the inhibitor (31) rather than the air quality of the target space (S), fluctuations in the air concentration can be suppressed with high accuracy.

[0087] In this embodiment, the controller (100) has an air conditioning control unit (110) and a dissipation control unit (120). This allows the dissipation operation by the dissipation device (30) to be performed without performing cooling or heating operations while the outdoor unit (11) is stopped.

[0088] (4) Variations The above embodiment may also be modified as follows. In the following description, we will primarily explain the differences from the above embodiment.

[0089] (4-1) Experimental variation 1 In the emission system (1) according to modified example 1, the current airborne concentration of the inhibitor (31) is estimated without calculating the target temperature of the inhibitor (31), and the heat source (33) is controlled accordingly.

[0090] As shown in Figure 6, when the emission system (1) starts operation, the air conditioning control unit (110) turns on the indoor fan (23). After the indoor fan (23) is turned on, in step ST201, the emission control unit (120) acquires information about the air condition of the air supplied to the inhibitor (31) from each sensor (61, 62, 63, 64). After acquiring the information about the air condition, in step ST202, the emission control unit (120) calculates the amount of volatilization of the inhibitor (31) in the current air condition using a characteristic formula. In the next step ST203, the emission control unit (120) estimates the current air concentration of the inhibitor (31). The emission control unit (120) calculates the air concentration from the amount of volatilization calculated in step ST202 and the spatial volume of the target space (S).

[0091] In the next step ST204, the emission control unit (120) determines whether the airborne concentration estimated in step ST203 is higher than the target concentration. If the estimated airborne concentration is higher than the target concentration (YES), the emission control unit (120) proceeds to step ST206. If the estimated airborne concentration is less than or equal to the target concentration (NO), the emission control unit (120) proceeds to step ST205.

[0092] In step ST205, the emission control unit (120) determines whether the airborne concentration estimated in step ST203 is lower than the target concentration. If the emission control unit (120) determines that the estimated airborne concentration is lower than the target concentration (YES), it proceeds to step ST207. If the emission control unit (120) determines that the estimated airborne concentration is the same as the target concentration (NO), it returns.

[0093] In step ST206, the dissipation control unit (120) controls the heat source (33) to cool the inhibitor (31). The dissipation control unit (120) controls the power supply (37) so that a positive current flows through the Peltier element (34). After step ST206, the system returns to the previous state.

[0094] Meanwhile, in step ST207, the emission control unit (120) controls the heat source (33) to heat the inhibitor (31). The emission control unit (120) controls the power supply (37) so that a reverse current flows through the Peltier element (34). After step ST207, the system returns to the previous state.

[0095] As described above, in this modified example 1, the emission control unit (120) controls the heat source (33) based on the amount of volatilization of the inhibitor (31), which is calculated based on information regarding the air quality of the air supplied to the inhibitor (31). By considering the amount of volatilization, the emission device (30) makes it easier to suppress fluctuations in the airborne concentration of the inhibitor (31) in the target space (S). In particular, the emission device (30) can maintain the airborne concentration at the target concentration with high accuracy, thereby increasing the inhibitory effect of the inhibitor (31) on insects (I).

[0096] (4-2) Modification 2 In the emission system (1) according to Modification 2, the emission control unit (120) controls the heat source (33) based on information about the air condition of the air supplied to the inhibitor (31). In Modification 2, the emission control unit (120) controls the heat source (33) based on temperature in particular.

[0097] As shown in Figure 7, when the dissipation system (1) starts operation, the air conditioning control unit (110) turns on the indoor fan (23). After the indoor fan (23) is turned on, in step ST301, the dissipation control unit (120) acquires information about the air condition of the air supplied to the inhibitor (31) from each sensor (61, 62, 63, 64). In particular, the dissipation control unit (120) acquires the output result of the temperature sensor (61).

[0098] After acquiring information about the air condition, in step ST302, the dissipation control unit (120) determines whether or not the temperature of the blown air will rise. The dissipation control unit (120) determines that the temperature of the blown air will rise, for example, when the output result of the temperature sensor (61) rises by 0.5°C or more. If the dissipation control unit (120) determines that the temperature will rise (YES), it proceeds to step ST304. If the dissipation control unit (120) determines that the temperature will not rise (NO), it proceeds to step ST303.

[0099] In step ST303, the dissipation control unit (120) determines whether or not the temperature of the blown air decreases. The dissipation control unit (120) determines that the temperature of the blown air decreases, for example, when the output result of the temperature sensor (61) decreases by 0.5°C or more. If the dissipation control unit (120) determines that the temperature decreases (YES), it proceeds to step ST305. If the dissipation control unit (120) determines that the temperature does not decrease (NO), it returns.

[0100] In step ST304, the dissipation control unit (120) controls the heat source (33) to cool the inhibitor (31). The dissipation control unit (120) controls the power supply (37) so that a positive current flows through the Peltier element (34). After step ST304, the system returns to the previous state.

[0101] Meanwhile, in step ST305, the emission control unit (120) controls the heat source (33) to heat the inhibitor (31). The emission control unit (120) controls the power supply (37) so that a current flows in the reverse direction to the Peltier element (34). After step ST305, the system returns to the previous state.

[0102] As described above, in this modified example 2, the emission control unit (120) controls the heat source (33) based on information regarding the temperature of the air supplied to the inhibitor (31). Since temperature changes particularly affect the amount of volatilization of the inhibitor (31), this modified example 2 can accurately suppress fluctuations in the airborne concentration of the inhibitor (31). Because calculations to determine the amount of volatilization and airborne concentration of the inhibitor (31) are unnecessary, this modified example 2 can reduce the load on the emission control unit (120).

[0103] (4-3) Modification 3 In the emission system (1) according to Modification 3, the emission control unit (120) controls the heat source (33) based on information about the air condition of the air supplied to the inhibitor (31). In Modification 3, the emission control unit (120) controls the heat source (33) based in particular on humidity.

[0104] As shown in Figure 8, when the dissipation system (1) starts operation, the air conditioning control unit (110) turns on the indoor fan (23). After the indoor fan (23) is turned on, in step ST401, the dissipation control unit (120) acquires information about the air condition of the air supplied to the inhibitor (31) from each sensor (61, 62, 63, 64). In particular, the dissipation control unit (120) acquires the output result of the humidity sensor (62).

[0105] After acquiring information about the air conditions, in step ST402, the dissipation control unit (120) determines whether or not the humidity of the blown air decreases. The dissipation control unit (120) determines that the humidity of the blown air decreases, for example, when the output result of the humidity sensor (62) decreases by 3% or more. If the dissipation control unit (120) determines that the humidity decreases (YES), it proceeds to step ST404. If the dissipation control unit (120) determines that the humidity does not decrease (NO), it proceeds to step ST403.

[0106] In step ST403, the emission control unit (120) determines whether or not the humidity of the blown air increases. The emission control unit (120) determines that the humidity of the blown air increases, for example, when the output result of the humidity sensor (62) increases by 3% or more. If the result is YES (humidity increases), the emission control unit (120) proceeds to step ST405. If the result is NO (humidity does not increase), the emission control unit (120) returns.

[0107] In step ST404, the dissipation control unit (120) controls the heat source (33) to cool the inhibitor (31). The dissipation control unit (120) controls the power supply (37) so that a positive current flows through the Peltier element (34). After step ST404, the system returns to the previous state.

[0108] Meanwhile, in step ST405, the emission control unit (120) controls the heat source (33) to heat the inhibitor (31). The emission control unit (120) controls the power supply (37) so that a reverse current flows through the Peltier element (34). After step ST405, the system returns to the previous state.

[0109] As described above, in this modified example 3, the emission control unit (120) controls the heat source (33) based on information regarding the humidity of the air supplied to the inhibitor (31). Since calculations to determine the amount of volatilization and the concentration in the air of the inhibitor (31) are not required, this modified example 3 can reduce the load on the emission control unit (120).

[0110] (4-4) Modification 4 In the emission system (1) according to Modification 4, the emission control unit (120) controls the heat source (33) based on information about the air condition of the air supplied to the inhibitor (31). In Modification 4, the emission control unit (120) controls the heat source (33) based on pressure in particular.

[0111] As shown in Figure 9, when the dissipation system (1) starts operation, the air conditioning control unit (110) turns on the indoor fan (23). After the indoor fan (23) is turned on, in step ST501, the dissipation control unit (120) acquires information about the air condition of the air supplied to the inhibitor (31) from each sensor (61, 62, 63, 64). In particular, the dissipation control unit (120) acquires the output result of the pressure sensor (63).

[0112] After acquiring information about the air condition, in step ST502, the dissipation control unit (120) determines whether or not the pressure of the blown air decreases. The dissipation control unit (120) determines that the pressure of the blown air decreases, for example, when the output result of the pressure sensor (63) decreases by 100 Pa or more. If the dissipation control unit (120) determines that the pressure decreases (YES), it proceeds to step ST504. If the dissipation control unit (120) determines that the pressure does not decrease (NO), it proceeds to step ST503.

[0113] In step ST503, the dissipation control unit (120) determines whether or not the pressure of the blown air increases. The dissipation control unit (120) determines that the pressure of the blown air increases, for example, when the output result of the pressure sensor (63) increases by 100 Pa or more. If the dissipation control unit (120) determines that the pressure is increasing (YES), it proceeds to step ST505. If the dissipation control unit (120) determines that the pressure is not increasing (NO), it returns.

[0114] In step ST504, the dissipation control unit (120) controls the heat source (33) to cool the inhibitor (31). The dissipation control unit (120) controls the power supply (37) so that a positive current flows through the Peltier element (34). After step ST504, the system returns to the previous state.

[0115] Meanwhile, in step ST505, the emission control unit (120) controls the heat source (33) to heat the inhibitor (31). The emission control unit (120) controls the power supply (37) so that a reverse current flows through the Peltier element (34). After step ST505, the system returns to the previous state.

[0116] As described above, in this modified example 4, the emission control unit (120) controls the heat source (33) based on information regarding the pressure of the air supplied to the inhibitor (31). Since calculations to determine the amount of volatilization and the concentration in the air of the inhibitor (31) are not required, this modified example 4 can reduce the load on the emission control unit (120).

[0117] (4-5) Modification 5 In the emission system (1) according to Modification 5, the emission control unit (120) controls the heat source (33) based on the information itself regarding the air condition of the air supplied to the inhibitor (31). In Modification 5, the emission control unit (120) controls the heat source (33) in particular based on the airflow rate.

[0118] As shown in Figure 10, when the dissipation system (1) starts operation, the air conditioning control unit (110) turns on the indoor fan (23). After the indoor fan (23) is turned on, in step ST601, the dissipation control unit (120) acquires information about the air condition of the air supplied to the inhibitor (31) from each sensor (61, 62, 63, 64). In particular, the dissipation control unit (120) acquires the output result of the airflow sensor (64).

[0119] After acquiring information regarding the air condition, in step ST602, the dissipation control unit (120) determines whether the airflow rate of the supplied air has increased. For example, if the output result of the airflow sensor (64) is 2m 3 When the airflow rate increases by more than / min, it is determined that the airflow rate of the supplied air has increased. If the airflow rate has increased (YES), the dissipation control unit (120) proceeds to step ST604. If the airflow rate has not increased (NO), the dissipation control unit (120) proceeds to step ST603.

[0120] In step ST603, the dissipation control unit (120) determines whether the airflow rate of the supplied air has decreased. For example, if the output result of the airflow sensor (64) is 2m 3 When the airflow rate decreases by more than / min, it is determined that the airflow rate has decreased. If the airflow rate has decreased (YES), the dissipation control unit (120) proceeds to step ST605. If the airflow rate has not decreased (NO), the dissipation control unit (120) returns.

[0121] In step ST604, the dissipation control unit (120) controls the heat source (33) to cool the inhibitor (31). The dissipation control unit (120) controls the power supply (37) so that a positive current flows through the Peltier element (34). After step ST604, the system returns to the previous state.

[0122] Meanwhile, in step ST605, the emission control unit (120) controls the heat source (33) to heat the inhibitor (31). The emission control unit (120) controls the power supply (37) so that a reverse current flows through the Peltier element (34). After step ST605, the system returns to the previous state.

[0123] As described above, in this modified version 5, the emission control unit (120) controls the heat source (33) based on the airflow rate of the air supplied to the inhibitor (31). Since changes in airflow rate particularly affect the amount of volatilization of the inhibitor (31), this modified version 5 can accurately suppress fluctuations in the airborne concentration of the inhibitor (31). Furthermore, since calculations to determine the amount of volatilization and airborne concentration of the inhibitor (31) are unnecessary, this modified version 5 can reduce the load on the emission control unit (120).

[0124] (4-6) Modification 6 In the emission system (201) according to modified example 6, as shown in Figure 11, the controller (200) has one general control unit (210) as the control unit for the air conditioning system (AC). The general control unit (210) is a control unit that integrates the control unit for the air conditioning unit and the control unit for the emission device. The general control unit (210) has an indoor control unit (111), an outdoor control unit (112), and an emission control unit (220).

[0125] In the dissipation system (201), the output results from the temperature sensor (61), humidity sensor (62), pressure sensor (63), and airflow sensor (64) are directly input to the dissipation control unit (220).

[0126] In the heat dissipation system (201), the power supply that provides current to the Peltier element (34) utilizes the power supply of the air conditioning unit (10). The heat source (233) has a switching circuit (237) for switching the direction of the current supplied to the Peltier element (34). The switching circuit (237) is controlled by the heat dissipation control unit (220).

[0127] In this modified example 6, the control unit of the air conditioning unit and the control unit of the radiant emission device are combined into a single integrated control unit (210), and current is supplied to the Peltier element (34) from the power supply of the air conditioning unit (10). This eliminates the need to separately install the radiant emission control unit (220) and the power supply, allowing for a more compact configuration of the radiant emission device.

[0128] (4-7) Modification 7 The emission device (330) of Modified Example 7 utilizes information regarding the air quality of the air supplied to the inhibitor (31) as information regarding the air concentration of the inhibitor (31) in the target space (S). Specifically, the emission device (330) utilizes the VOC concentration, which is the concentration of VOCs (Volatile Organic Compounds) in the target space (S). As shown in Figure 12, the emission device (330) of the emission system (301) has two VOC sensors: a first VOC sensor (365) and a second VOC sensor (366). The first VOC sensor (365) is located upstream of the casing (32) in the air conditioning passage (25). The second VOC sensor (366) is located downstream of the casing (32) in the air conditioning passage (25).

[0129] As shown in Figure 13, the output results from the first VOC sensor (365) and the second VOC sensor (366) are input to the emission control unit (320) of the controller (300). The emission control unit (320) uses each output result to control the temperature of the inhibitor (31).

[0130] Next, the emission operation of the emission device (330) in modified example 7 will be described. When the emission system (301) starts operation, the air conditioning control unit (110) turns on the indoor fan (23). After the indoor fan (23) is turned on, as shown in Figure 14, the emission control unit (320) acquires information about the air condition in step ST701. The emission control unit (320) acquires the output results of the temperature sensor (61), humidity sensor (62), pressure sensor (63), airflow sensor (64), first VOC sensor (365), and second VOC sensor (366). After acquiring the output results, in step ST702, the emission control unit (120) estimates the airborne concentration of the inhibitor (31). The emission control unit (320) estimates the amount of volatile components (G) generated from the absolute value of the difference between the output result of the first VOC sensor (365) and the output result of the second VOC sensor (366), and estimates the current airborne concentration from the estimated amount of generated components and the spatial volume of the target space (S).

[0131] In the next step ST703, the emission control unit (320) determines whether the airborne concentration estimated in step ST702 is higher than the target concentration. If the estimated airborne concentration is higher than the target concentration (YES), the emission control unit (320) proceeds to step ST705. If the estimated airborne concentration is less than or equal to the target concentration (NO), the emission control unit (320) proceeds to step ST704.

[0132] In step ST704, the emission control unit (320) determines whether the airborne concentration estimated in step ST702 is lower than the target concentration. If the emission control unit (320) determines that the estimated airborne concentration is lower than the target concentration (YES), it proceeds to step ST706. If the emission control unit (320) determines that the estimated airborne concentration is the same as the target concentration (NO), it returns.

[0133] In step ST705, the dissipation control unit (320) controls the heat source (33) to cool the inhibitor (31). The dissipation control unit (320) controls the heat source (33) so that a positive current flows through the Peltier element (34). After step ST705, the system returns to the previous state.

[0134] Meanwhile, in step ST706, the emission control unit (120) controls the heat source (33) to heat the inhibitor (31). The emission control unit (120) controls the heat source (33) so that a current flows in the reverse direction through the Peltier element (34). After step ST706, the system returns to the previous state.

[0135] In this modified example 7, the emission control unit (320) controls the heat source (33) using information regarding the airborne concentration of the inhibitor (31) in the target space (S). In particular, the information regarding the airborne concentration is the output result of the first VOC sensor (365) and the second VOC sensor (366). This allows for accurate estimation of the level of airborne concentration in the target space (S), and the emission device (330) can accurately suppress fluctuations in the airborne concentration of the inhibitor (31).

[0136] In this modified example 7, the emission control unit (320) compares the estimated airborne concentration with the target concentration and controls the heat source (33). This makes it possible to keep the airborne concentration of the inhibitor (31) stable relative to the target concentration, so that the emission device (30) can enhance the inhibitory effect on insects (I) by the inhibitor (31).

[0137] <Other Embodiments> The agents emitted by the dispersal device (30,330) are not limited to inhibitors, but may also be repellents and insecticides.

[0138] The device on which the radiating device (30, 330) is placed may be any device other than the indoor unit (20) as long as it is placed within the target space (S) and adjusts the temperature or humidity of the air. For example, the radiating device (30, 330) may be placed in an air purifier, humidifier, circulator, fan, etc.

[0139] The dispersion devices (30, 330) may have the function of blowing volatile components (G) into the target space (S). In this case, the dispersion devices (30, 330) may be placed individually in the target space (S) rather than being placed inside the indoor unit (20). Furthermore, it is preferable that the sensors (61, 62, 63, 64, 365, 366) that acquire information about the air blown to the inhibitor (31) are placed on the dispersion devices (30, 330) themselves.

[0140] The heat dissipation devices (30, 330) may be located upstream of the indoor heat exchanger (22).

[0141] The heat source (33) may have only a cooling function and no heating function. For example, the heat source (33) may be a device for air-cooling or water-cooling the inhibitor (31).

[0142] Even in configurations where the air conditioning control unit (110) and the emission control unit (120, 220, 320) are not integrated, the emission control unit (120, 220, 320) may directly acquire the output results of the temperature sensor (61), humidity sensor (62), pressure sensor (63), and airflow sensor (64).

[0143] The first VOC sensor (365) and the second VOC sensor (366) may be sensors used to control the air conditioning unit (10). In this case, the emission control unit (320) obtains the output results of the first VOC sensor (365) and the second VOC sensor (366) acquired by the air conditioning control unit (110) via the router (130) and the server device (140).

[0144] In Modifications 1-5 and 7, the radiating devices (30, 330) were equipped with a separate power supply (37) from the air conditioning unit (10). Even in configurations like those in Modifications 1-5 and 7, the radiating devices (30, 330) may use the power supply of the air conditioning unit (10) as their power source.

[0145] As described above in the embodiment, modification 1, and modification 2, when utilizing the output result of the temperature sensor (61), the temperature sensor used may be changed depending on the arrangement of the inhibitor (31). For example, when the inhibitor (31) is located downstream of the indoor heat exchanger (22), the output result of the temperature sensor that detects the temperature of the air blown out from the outlet (21b) may be used to control the dissipation devices (30, 330). When the inhibitor (31) is located upstream of the indoor heat exchanger (22), the output result of the temperature sensor that detects the temperature of the air drawn in from the intake (21a) may be used to control the dissipation devices (30, 330).

[0146] There may be multiple temperature sensors (61). For example, there may be both a temperature sensor that detects the temperature of the air drawn in from the intake port (21a) and a temperature sensor that detects the temperature of the air blown out from the outlet port (21b). For controlling the dissipation device (30, 330), all of the detection results from the multiple temperature sensors may be used, or the temperature sensors to be used may be selected according to the arrangement of the inhibitors (31).

[0147] The humidity sensor (62), pressure sensor (63), and airflow sensor (64) are not required. Also, the temperature sensor (61), humidity sensor (62), pressure sensor (63), and airflow sensor (64) are not required to be used for the purpose of controlling the heat source (33) of the dissipation device (30, 330). In this case, the dissipation control unit (120, 220, 320) may acquire information indicating the operating state of the air conditioning unit (10) as information regarding the air condition of the air supplied to the inhibitor (31), and control the heat source (33) based on the information indicating the operating state. For example, when a signal to perform heating operation is input to the air conditioning unit (10), the dissipation control unit (120, 220, 320) may control the heat source (33) to cool the inhibitor (31). Furthermore, if the air conditioning unit (10) is equipped with a dehumidification operation function, when a signal to perform dehumidification operation is input to the air conditioning unit (10), the heat source (33) may be controlled to cool the inhibitor (31). Also, when a signal to change the airflow level is input to the air conditioning control unit (110), the emission control unit (120, 220, 320) may control the heat source (33) to cool or heat the inhibitor (31) based on the airflow that can be determined from the changed airflow level.

[0148] The target temperature of the inhibitor (31) may be estimated by a trained model that has been trained using information about the air conditions of the air supplied to the inhibitor (31) and the temperature at which the airborne concentration of the inhibitor (31) reaches the target concentration under those air conditions as training data. Separately, the airborne concentration of the inhibitor (31) in the target space (S) may be estimated by a trained model that has been trained using information about the air conditions of the air supplied to the inhibitor (31) and the airborne concentration when the heat source (33) is not activated under those air conditions as training data. These trained models may be stored in the memory units (121, 221, 321) of the emission control units (120, 220, 320) or in the server device (140).

[0149] While embodiments and modifications have been described above, it will be understood that a variety of changes in form and details are possible without departing from the spirit and scope of the claims. Furthermore, the embodiments, modifications, and other embodiments described above may be combined or substituted as appropriate, as long as they do not impair the functions covered by this disclosure.
