Description

Temperature load management device, temperature load management method, and computer program

Technical Field

The present disclosure relates to a temperature load management apparatus, a temperature load management method, and a computer program.

Background

If a person is exposed to an extreme temperature environment such as a hot environment or a cold environment for a long period of time, there is a psychological burden such as discomfort or anxiety due to heat or cold, and there is a physical burden such as injury to the visceral system or physiological burden to the autonomic nervous system due to a large amount of perspiration, trembling movements, and body temperature increases (decreases).

Patent document 1 proposes a portable air conditioning room that can be easily evacuated and rested when an operator such as a hot room has a sense of discomfort such as heatstroke.

For example, even if the room temperature environment is entered immediately after exposure to the hot environment, the influence of heat does not disappear, it is difficult to concentrate on work immediately, and the like. Specifically, if dehydration due to continuous perspiration, localized cooling in a cool room due to wearing a shirt wetted with perspiration, continuous discomfort, or the like occurs, the work efficiency is reduced. The long-term accumulation of heat stress in the human body may cause the above-mentioned physical and psychological stress, and other physical and psychological stresses may be generated due to the stress.

Accordingly, in the conventional air conditioner, the following temperature control is performed in consideration of comfort: lowering the target set temperature when the outside air temperature becomes high; the target set temperature is raised when the outside air temperature becomes low. However, in this temperature control, when the air-conditioned room is moved out from the outside, or the air-conditioned room is moved from the air-conditioned room to the non-air-conditioned room, the change in the ambient temperature increases, and so-called heat shock may be felt. The physical condition may be deteriorated due to supercooling, that is, a so-called air conditioning disease may occur.

Patent document 2 proposes to perform a cooling operation so as to maintain a temperature difference between an outside air temperature and an indoor temperature within 5 to 7 ℃ in order to alleviate heat shock and prevent supercooling.

Disclosure of Invention

Technical problem to be solved by the invention

However, in the portable air conditioning room disclosed in patent document 1, since the user is cooled uniformly by adjusting the temperature in a narrow room to a low temperature, a person may feel supercooled depending on the user, and the other person may feel insufficient cooling.

In the air conditioner of patent document 2, control to reduce the temperature difference is performed to prevent supercooling in an outdoor hot environment, and thus it takes time to reduce the influence of the outside air temperature on the temperature load of the mind and body. Thus, the burden on the mind and body due to the hot environment is continued during the period of time before the mind and body of the person is restored to a stable state.

Detailed Description

Embodiments of the present disclosure will be described below with reference to the drawings. The following embodiments are merely preferred examples in nature, and are not intended to limit the present invention, its application, or the scope of its application.

(first embodiment)

Temperature load reducing model

It is known that even if a person exposed to a hot environment is relieved of a heat load in a low-temperature environment of normal temperature or lower for a short period of time, the adverse effect on the mind and body is eliminated, and the attention can be restored. That is, by rapidly relieving the Heat Stress in the body, the physical and psychological Stress is difficult to continue and the vitality is easily recovered.

Therefore, when exposed to an extreme temperature environment or moved indoors, air conditioning control is performed by temporarily providing an opposite temperature environment above or below the normal temperature to the temperature environment that the mind and body is forced to withstand, specifically, providing a temperature environment below the normal temperature if it is a load due to a hot environment; if the load is caused by a cold environment, the influence of the temperature load can be reduced by providing a temperature environment of normal temperature or higher.

It is generally considered that: giving a large temperature difference is not good for the human body. However, the present inventors have experimentally clarified that if a low-temperature environment (for example, 21 ℃) is entered after a hot environment (for example, 36 ℃) is accommodated, the hot load (decrease in parasympathetic function, increase in heart rate, increase in perspiration amount, etc.) can be reduced while rapidly decreasing the skin temperature (the case temperature) as compared with the case of entering a general indoor environment (around 26 ℃), and have conceived a temperature load reducing model described later based on this insight. The present inventors have focused on the realization of a temperature load reduction model by rapidly adjusting the skin surface or other skin surface temperature to a temperature lower than the equilibrium state in a normal temperature environment (in the case of a hot environment) or to a temperature higher than the equilibrium state in a cold environment, thereby promoting heat exchange between the skin temperature and the deep body temperature, and reducing the influence of the temperature load on the whole body due to the hot environment or the cold environment. Based on the temperature load reduction model, an ambient temperature (reduction temperature) and a residence time (reduction time) suitable for reducing the influence of the temperature load can be calculated.

The temperature load HS (t) (t is time) can be described as follows, assuming that the core body temperature, which is a representative value for evaluating the temperature load (heat stress) of the body, is BTc, the skin temperature (temperature of the skin surface) is BTs, and the heat stress amount is α×Δbt (Δ represents a temperature difference based on the normal temperature).

Ambient temperature: HS (t) =0

Hot environment: HS (t) =αc×ΔBTc (t) +αs×ΔBTs (t)

Here, Δ BTs and Δ BTc are the case temperature and the offset amount of the deep body temperature based on the equilibrium state at room temperature, and αs and αc are the heat stress coefficients based on the case and the deep volume, respectively. Note that, in a normal temperature environment, Δbt=0, and therefore, the heat stress is 0.

The deep portion is indirectly affected by the outside air temperature by heat exchange with the casing. If the heat exchange amount HE between the outside air, the case, and the deep part is used, the body temperature BT at time t can be described as follows.

BTs(t)＝BTs(t－1)－HEsc(t－1)/αs+HEes(t－1)/αs

BTc(t)＝BTc(t－1)+HEsc(t－1)/αc

Here, hes is the heat exchange amount between the outside air and the casing, and HEsc is the heat exchange amount between the casing and the deep portion.

HEsc may also be expressed as hesc=pl+pc. PL is a regulatory element that relies on dynamic thermoregulation functions under physiological control, such as by blood flow (including perspiration) and the mechanisms of heat dissipation from muscles, thermogenesis, etc. PC is a regulatory element that does not rely on a thermoregulation function such as physical heat transfer by a static substance, such as muscles in the deep-housing vicinity.

The blood Wen Zaisheng related to PL is directly affected by the temperature of the casing in terms of its physical structure. Therefore, the case temperature has an effect on both PL and PC.

As described above, when the body temperature control function is lowered by long-term exposure to a hot environment, the case temperature is quickly lowered to a physical equilibrium state or lower, so that the PC and PL can promote early alleviation of αc×Δ BTc corresponding to deep heat stress.

FIG. 1 shows the change of the case temperature with time in the case where a person repeatedly performs the operation of entering the normal temperature environment (26 ℃) and the low temperature environment (21 ℃) after the person is adapted to the hot environment (36 ℃).

As shown in fig. 1, when a person enters a normal temperature environment (26 ℃) after having been adapted to a hot environment (36 ℃), the case temperature does not drop completely to the reference value in the equilibrium state within about 20 minutes, and thus the heat stress continues for a long time. In particular, since the deep temperature indirectly fluctuates by the heat exchange process between the deep portion and the outer case, it is expected that the time to receive the deep heat stress will be longer. On the other hand, when a person enters a low-temperature environment (21 ℃) which is a temperature equal to or lower than normal temperature after being in a hot environment (36 ℃), the case temperature rapidly drops to or below a reference value of an equilibrium state at normal temperature. That is, through the heat exchange process between the case and the deep portion caused by the external air conditioning operation, early relief of the deep portion heat stress can be expected.

As a result of intensive studies, the present inventors have found that, assuming that the time elapsed after a person enters an environment capable of reducing a temperature load (hereinafter, also referred to as a reducing environment) is t, the case temperature BTs (t) can be described by a temperature (hereinafter, also referred to as a load temperature) TL of the environment to which the temperature load is applied and a temperature (hereinafter, also referred to as a reducing temperature) TR of the reducing environment using a temperature load reducing model as described below.

BTs (t) =β1×ln (t) +β … … formula (1)

β1=a1×tr+b1×tl-c1 … … (2)

β2=a2×tr+b2×tl-c2 … … (3)

Where ln is the natural logarithm and A1, B1, C1, A2, B2, C2 are model parameters.

Fig. 2 shows: the average value (broken line) of the results obtained by measuring the time change of the shell temperature when the actions of the healthy adult male and female 30 persons respectively enter the normal temperature environment (26 ℃) and the low temperature environment (21 ℃) are performed three times after the healthy adult male and female 30 persons are suitable for the hot environment (36 ℃); and calculating the model parameters A1, A2, B1, B2, C1, C2 using the actual measurement results, and predicting the value of the case temperature BTs (t) based on the formulas (1) to (3) (solid line). The values of model parameters A1, B1, C1, A2, B2, and C2 calculated from the actual measurement results shown in fig. 2 were 0.05, -0.03, 0.60, 0.08, 0.17, and, -26.3, respectively.

In the temperature load reduction model represented by the formulas (1) to (3), when the target value of the case temperature BTs, which is the reference for reducing the deep heat stress, is set to 33 ℃ lower than the average equilibrium state and the time t for which the person is exposed to the environment in which the temperature load is reduced (hereinafter, also referred to as the reduction time) is set to 10 minutes, the relationship of the reduction temperature TR corresponding to the load temperature TL can be described simply as follows.

Tr=39.5-0.47×tl … … type (4)

According to equation (4), by setting the target value of the case temperature BTs to be equal to or less than the reference value of the equilibrium state, the ideal relief temperature TR can be calculated from the load temperature (outside air temperature) TL.

As described above, in the temperature load reduction model in which the correlations among the case temperature BTs, the load temperature TL, the reduction temperature TR, and the reduction time t are described, by setting the model parameters according to the envisaged situation, it is possible to realize air conditioning control for reducing the heat stress accumulated in the human body in the hot environment as early as possible. Specifically, in the temperature load relief model, if the case temperature BTs is set to the target value and one of the load temperature TL, the relief temperature TR, and the relief time t is input, the other one of the relief temperature TR and the relief time t can be output.

In the temperature load reduction model represented by the formulas (1) to (3), model parameters A1, B1, C1, A2, B2, and C2 estimated to be the optimal reduction temperature TR and the optimal reduction time t are calculated based on parameters β1 and β2 obtained by logarithmic approximation of actual measurement values of the load temperature TL, the reduction temperature TR, the reduction time (time when the environment in which the temperature load is reduced is used) t, and the case temperature BTs.

Regarding air conditioning control for a temperature load-reducing environment, by constants-adding a part of the four parameters (TL, TR, t, BTs), a reducing temperature TR and a reducing time t required for reducing the case temperature BTs by a predetermined value (for example, 0.5 to 1.5 ℃) can be calculated from the load temperature TL.

The temperature load reduction models represented by the formulas (1) to (3) are models in the case where a person receives a strong temperature load from a hot environment or a cold environment. Specifically, the model is mainly one in which a severe temperature load of 5℃or more is applied from the normal temperature (25 to 28℃in summer and 18 to 22℃in winter). In other words, since the heat stress is hard to accumulate in the body because the body temperature adjusting function normally functions in an environment close to normal temperature, the state of change in the case temperature BTs also deviates from the model types (1) to (3). In an environment close to normal temperature, since it is not necessary to reduce the temperature load, air conditioning control for reducing the environment by the temperature load reduction model may not be performed.

The temperature load reduction models represented by the formulas (1) to (3) are designed based on the heat stress in the hot environment in summer, but if the model parameters A1, B1, C1, A2, B2, and C2 are calculated by acquiring the supporting data in winter in advance, the reduction temperature TR and the reduction time t for the negative heat stress in the cold environment in winter can be calculated similarly. The model parameters in winter can be estimated from the average air temperature of 12 to 2 months, and the load temperature to which the temperature load reduction model is applied and the load temperature to which the cold load is applied can be, for example, 10 ℃.

FIG. 3 shows the actions of a healthy adult male and female 30 after being adapted to a low temperature environment (21 ℃) and entering a high temperature environment (36 ℃) respectivelyThe average of the results of the three measured shell temperatures over time. When β1 and β2 in the formula (1) were logarithmically approximated by using the actual measurement results shown in FIG. 3, the results were 0.533 and 33.53 (R ² =0.95). That is, β1 becomes negative in comparison with β1 when subjected to a hot load, and β1 becomes positive when subjected to a cold load.

Temperature load management device

Fig. 4 is a block diagram of an air conditioning system 100 including the temperature load management device 20 according to the first embodiment. The temperature load management device 20 of the present embodiment is used when exposing the user to a second environment (reduced environment) for reducing the temperature load accumulated in the user in the first environment (hot environment or cold environment).

As shown in fig. 4, the temperature load management device 20 mainly includes a control unit 10. The control unit 10 sets the case temperature BTs as a target value based on the correlation (i.e., the temperature load alleviation model) between the case temperature BTs of the user, the load temperature TL which is the temperature of the first environment, the alleviation temperature TR which is the temperature of the second environment, and the alleviation time t which is the time for which the user is exposed to the second environment, and outputs one of the load temperature TL, the alleviation temperature TR, and the alleviation time t as input, and the other of the alleviation temperature TR and the alleviation time t.

The temperature load management device 20 may further include a storage unit that stores the model represented by the above-described formulas (1) to (3) and model parameters A1, A2, B1, B2, C1, C2 calculated in advance from the actual measurement values. The temperature load management device 20 may further include an input portion or a display portion for setting the case temperature BTs to a target value, or inputting one of the load temperature TL, the relief temperature TR, and the relief time t, or outputting the other of the relief temperature TR and the relief time t. The temperature load management device 20 may further include a measurement unit for measuring the outside air temperature, which is the load temperature TL. As the outside air temperature that becomes the load temperature TL, the temperature load management device 20 may use outside air temperature information acquired from a network such as the amada.

The temperature load management device 20 includes a microcomputer or the like, and executes a program by the computer to perform the respective functions of the control unit 10 or the like, that is, the temperature load management method of the present embodiment. The computer includes a processor operating according to a program as a main hardware structure. The type of the processor is not particularly limited as long as the processor can realize the functions by executing the program, and may be configured by one or more electronic circuits including a semiconductor Integrated Circuit (IC) or LSI (large scale integration; large-scale integrated circuit), for example. The plurality of electronic circuits may be integrated on one chip or may be provided on a plurality of chips. The plurality of chips may be integrated in one device or may be dispersed in a plurality of devices. The program is stored in a non-transitory storage medium such as a computer-readable ROM, an optical disk, a hard disk drive, or the like. The program may be stored in advance in a storage medium, or may be supplied to the storage medium via a wide area communication network including a network or the like.

In the case where the temperature load management device 20 includes a storage unit, a recording medium such as a RAM or the like that can be read from and written to by a computer can be used as the storage unit. In the case where the temperature load management device 20 includes an input unit, for example, a keyboard, a mouse, a touch panel, or the like can be used as the input unit. In the case where the temperature load management device 20 includes a display unit, a monitor capable of displaying an image, such as a CRT or a liquid crystal display, may be used as the display unit. In the case where the temperature load management device 20 includes a measurement unit, the measurement unit may be a temperature sensor carried by a user, or may be a temperature sensor provided in a plurality of places (a room, a public place, an outdoor place, or the like). In the latter case, the temperature around the user is calculated from the temperature history data measured by the temperature sensors provided at the plurality of locations and the movement history data of the user. The movement history data of the user may be stored in advance, or may be input by the user as appropriate or according to the plan setting of the day.

The installation form of the temperature load management device 20 is not particularly limited, and may be installed on a remote controller of an air conditioner (air conditioner) 30 described later, for example. In this case, the temperature load management device 20 may be configured by a microcomputer, a memory, a touch panel, or the like mounted on a remote controller.

In the temperature load management device 20, as a temperature load reduction model showing the correlation among the case temperature BTs, the load temperature TL, the reduction temperature TR, and the reduction time t, for example, the models represented by the above formulas (1) to (3) can be used. The temperature load reduction model used in the temperature load management device 20 is not particularly limited as long as it describes the correlation among the case temperature BTs, the load temperature TL, the reduction temperature TR, and the reduction time t.

In the temperature load management device 20, when the first environment is a hot environment or a cold environment, the model parameters A1, A2, B1, B2, C1, C2 may be set in consideration of clothing worn by the user. For example, when calculating the parameters, the model parameters may be set according to seasons using data measured when the short sleeve is worn in summer and the long sleeve is worn in winter.

The temperature load alleviation model is premised on physical heat transfer to the deep body temperature through the shell temperature BTs. Since the wear is thin in summer, the case temperature BTs is easily affected by the outside air temperature (load temperature TL) directly. On the other hand, since the heat retaining force of the clothes cannot be ignored in winter, the case temperature BTs estimated from the outside air temperature increases as compared with the temperature load reduction model for a hot environment, and the effect to which a person is subjected also changes according to the reduction temperature TR, so that in the temperature load reduction model for a cold environment, correction of model parameters according to wearing and wearing of the clothes is required.

Specifically, when the environment in which the temperature load is reduced is an indoor environment, for example, when the environment is exposed to the temperature load in a cold environment, the skin temperature in the state in which the coat is removed is measured as the case temperature BTs, the skin temperature in the state in which the coat is removed is measured as the case temperature BTs in the reduced environment, and the model parameters of the temperature load reduction model for the cold environment are calculated from the measured fluctuation data of the case temperature BTs. On the other hand, when the environment in which the temperature load is reduced is located outdoors, the skin temperature in the state of wearing the coat can be measured as the case temperature BTs, and the model parameters can be calculated based on the measured variation data of the case temperature BTs, both when the environment is exposed to the temperature load in the cold environment and when the environment is reduced.

In the temperature load management device 20, the model parameters A1, A2, B1, B2, C1, and C2 may be adjusted according to the attributes of the user. For example, the model parameters corresponding to the attributes of the user group such as age, sex, physical constitution (body weight, BMI, etc.), normal temperature, medical history, etc. may be calculated and set by acquiring supporting data based on the temperature load reduction model. In this way, the air conditioning control based on the temperature load reduction model can be performed according to the characteristics of the user such as a primary school or a nursing home.

In the temperature load management device 20, the load temperature TL may be corrected in consideration of at least one of the humidity, the wind speed, and the radiation temperature in the first environment. The temperature load perceived by a person varies according to humidity, wind speed, radiation temperature, etc. For example, in the case where the temperature environment subjected to a hot load is 30 ℃ or higher, when the humidity is changed from 50% to 70%, the body temperature may be about 1 to 2 ℃ higher than the actual temperature. Therefore, when a hot load is applied in a high humidity environment, the relief temperature TR or the relief time t may be calculated by correcting the outside air temperature (load temperature) TL to TLh in consideration of humidity according to TLh =tl+γ (γ is a correction value (about 1 to 2 ℃) of the outside air temperature) and inputting the corrected value to the temperature load relief model.

Air conditioning system structure

As shown in fig. 4, the air conditioning system 100 may be constituted by the temperature load management device 20 and the air conditioning device 30. The air conditioner 30 performs air conditioning of the second environment (the reduced environment) in which the temperature load is reduced, based on the reduced temperature TR or the reduced time t output from the control unit 10 of the temperature load management device 20.

In the air conditioning system 100, air conditioning control based on the temperature load reduction model is mainly performed when the air temperature (load temperature TL) of the strong temperature load is received from the hot environment or the cold environment (first environment). In summer, when the outside air temperature is, for example, 31 ℃ or higher, and in winter, when the outside air temperature is, for example, 10 ℃ or lower, air conditioning control by the temperature load reduction model can be performed. On the other hand, in the range of the outside air temperature of about 20 to 30 ℃, air conditioning control at a gentle temperature gradient may be performed around the normal temperature (summer: 25 to 28 ℃). In the range of about 10 to 20℃outside air temperature, air conditioning control at a gentle temperature gradient may be performed around the normal temperature (18 to 22℃in winter).

The air conditioning system 100 may further include an adjusting portion 40, and the adjusting portion 40 may be configured such that a user can change the relief temperature TR or the relief time t outputted from the control portion 10. In other words, the user may also manually change the relief temperature TR or the relief time t to a specific value through a remote controller or the like of the air conditioner 30. Fig. 5 illustrates a relationship between the relief temperature TR (set temperature for load relief) and the load temperature TL (ambient temperature under load) obtained by the temperature load relief model, and fig. 6 schematically shows a case where the relief temperature or the slope thereof illustrated in fig. 5 is changed to a specific value or slope by the user.

The air conditioning system 100 may further include a detection portion 50 such as a thermal imager that detects the user's housing temperature BTs. In this case, the air conditioner 30 may change the reduced temperature TR so that the difference between the reduced temperature TR and the normal temperature becomes equal to or less than a second predetermined value (for example, 5 ℃) or may give an alarm to the user to terminate the exposure in the second environment (reduced environment) when the difference between the case temperature BTs detected by the detecting unit 50 and the target value thereof exceeds the first predetermined value (for example, 2 ℃). Thus, excessive expansion of the body temperature fluctuation of the user can be suppressed. The alarm information may be transmitted to, for example, a mobile terminal of a user individual corresponding to the network registered in advance.

The air conditioning system 100 may further include a measuring device (sensor) such as an extreme ambient temperature (outside air temperature) that causes a load on the user. For example, the outside air temperature and the room temperature (the temperature around the user) may be measured by sensors, and the control unit 10 may output the relief temperature TR or the relief time t based on the temperature load relief model using the measured information, and the air conditioning device 30 may supply cool air or warm air to the relief environment based on the output value.

The air conditioning system 100 may be configured as a closed indoor air conditioning system that controls the temperature of the entire room to a reduced temperature TR, such as a Restroom (rest room). With such a rest room, a person who comes from outdoors on a very hot day (a very cold day) can reduce the temperature load before starting an indoor work or the like.

The air conditioning system 100 may be configured as an open type air conditioning system that controls the temperature of a local space in a room to a reduced temperature TR by, for example, locally supplying cool air or warm air from a wall of an inlet.

The air conditioning system 100 may be configured to be usable outdoors and to be movable and temporarily installed. In this case, the air conditioning system 100 may be configured as a closed type air conditioning chamber such as a temporary rest room, or may be configured as an open type air conditioning system capable of locally cooling or heating such as a temporary air cooler or a temporary warm air blower.

When the air conditioning system 100 is configured as an indoor-outdoor-open air conditioning system, as shown in fig. 7, it is necessary to supply air, which is substantially different from the air state of the use place 200, to the user 250. In this case, the air conditioning control may be performed using only the surrounding environment of the user 250 as the environment for relief. Therefore, in order to enhance the local air conditioning effect, it is also possible to blow vertically downward from the air supply port 201 provided above the use place 200 toward the head of the user 250 or blow horizontally from the air supply port 202 provided at the side of the use place 200 toward the front of the user 250.

The parameters of the temperature load reduction model used in the temperature load management device 20 are calculated on the premise of a closed space such as an indoor space having a constant temperature, but in the open air conditioning system 100, cool air, warm air, or the like is directly supplied from the air conditioning device 30 close to the user. In this case, the temperature decrease TR set by the temperature load decrease model may be a temperature at a position deviated from the air-conditioning apparatus 30 air supply to the user side, for example, 1 m. The target value of the case temperature BTs, which is a criterion for load reduction, may be set to, for example, 0.5 ℃ lower than the case where a closed space such as an indoor space is assumed, if the target value is a hot load; in the case of a cold load, it may be set to, for example, 0.5 ℃.

In the open air conditioning system 100, it is necessary to supply air having a temperature greatly different from the outside air temperature (load temperature TL). Therefore, if the open type air conditioning system 100 is operated at all times, the cost increases, and therefore, when the object sensor or the like detects that the user has approached the air outlet of the air conditioning apparatus 30, the air conditioning system 100 may be automatically operated. In this case, when the air conditioning system 100 is not in operation, a certain amount of cool air or warm air can be circulated in the air conditioning device 30, so that the cost required for temperature control can be reduced, and the cool air or warm air can be immediately supplied at the time of operation.

The temperature difference between the target temperature reduction temperature TR set as the target temperature for air conditioning control by the air conditioning system 100 and the load temperature TL (for example, the outside air temperature) is large, and the use time (reduction time t) of the reduction temperature TR is limited to, for example, about 5 minutes to 15 minutes. Therefore, it is effective to reduce the cost to perform the temperature adjustment in a short time at a minimum. To achieve this, for example, it is also possible to have a function of remotely operating the air conditioning system 100 through a network. Specifically, the light environment such as the room may be quickly adjusted to the light temperature TR in a short time in combination with the predetermined time of entering the room set by the remote operation.

The air conditioning system 100 may further include a detection portion 60, an object sensor or the like that mitigates the environment for detecting that the user has entered the room or the like by the detection portion 60. In this case, the air conditioning system 100 may perform the air conditioning control based on the temperature load reduction model only after the detection unit 60 detects that the user has entered the environment for reduction. The air conditioner 30 may end the air conditioning at the relief temperature TR when the relief time t elapses after the detection unit 60 detects that the user has entered the relief environment. For example, after the person has entered the room is detected by an object sensor or the like in the vicinity of the predetermined time of entering the room set by the remote operation, the temperature of the environment to be reduced may be automatically returned to an appropriate temperature (for example, about 26 to 28 ℃) after the time t for reducing the temperature load set by the temperature load reducing model has elapsed (for example, 10 to 15 minutes).

Effects of the first embodiment

The temperature load management device 20 of the present embodiment is used when exposing a user to a second environment for reducing the temperature load accumulated in the user in the first environment. The temperature load management device 20 mainly includes a control unit 10. The control unit 10 sets the case temperature BTs as a target value based on the correlation (i.e., the temperature load alleviation model) between the case temperature BTs of the user, the load temperature TL which is the temperature of the first environment, the alleviation temperature TR which is the temperature of the second environment, and the alleviation time t which is the time for which the user is exposed to the second environment, and outputs one of the load temperature TL, the alleviation temperature TR, and the alleviation time t as input, and the other of the alleviation temperature TR and the alleviation time t. Therefore, the temperature load relief temperature TR or the relief time t can be obtained based on the load temperature TL so that the case temperature BTs of the user reaches the target value. Therefore, by performing air conditioning of the second environment based on the reduced temperature TR or the reduced time t, heat exchange between the skin temperature and the deep body temperature can be promoted, and the influence of the temperature load on the mind and body can be quickly reduced. Specifically, it is possible to suppress a decrease in parasympathetic activity of the user, dehydration due to excessive perspiration, an increase in heart rate in a hot environment, and the like. Can alleviate the decrease of body temperature regulating function, which occurs after excessive perspiration caused by long-time exposure to hot environment, and is manifested by reduced perspiration. By reducing such a temperature load as early as possible, for example, the work efficiency at the start of an indoor work can be improved.

In the temperature load management device 20 of the present embodiment, the temperature load reduction model may be represented by the formulas (1) to (3). By experimentally calculating the model parameters in advance in this way, the correlations among the user's case temperature BTs, load temperature TL, relief temperature TR, and relief time t can be obtained. That is, the temperature load reduction model for a hot environment and the temperature load reduction model for a cold environment can be easily constructed.

In the temperature load management device 20 of the present embodiment, when the first environment is a hot environment or a cold environment, the model parameters may be set in consideration of clothing worn by the user. In this way, the reduction temperature TR or the reduction time t for reducing the influence of the temperature load caused by the cold environment can be more accurately obtained.

The temperature load management device 20 according to the present embodiment may adjust the model parameters according to the attributes of the user. In this way, the reduction temperature TR or the reduction time t suitable for reducing the influence of the temperature load can be obtained from the attribute of the user.

The temperature load management device 20 of the present embodiment may correct the load temperature TL in consideration of at least one of the humidity, the wind speed, and the radiation temperature in the first environment. Thus, by accurately evaluating the load temperature TL, the relief temperature TR or the relief time t for relieving the influence of the temperature load can be more accurately obtained.

The air conditioning system 100 of the present embodiment mainly includes the temperature load management device 20 and the air conditioning device 30. The air conditioner 30 performs air conditioning of the second environment based on the relief temperature TR or the relief time t output from the control unit 10 of the temperature load management device 20. In this way, since the air conditioning device 30 performs air conditioning of the second environment in accordance with the reduced temperature or the reduced time outputted from the control unit 10, heat exchange between the skin temperature and the deep body temperature can be promoted, and the influence of the temperature load on the mind and body can be quickly reduced.

The air conditioning system 100 of the present embodiment may be configured as an outdoor type air conditioning system. Thus, by reducing the accumulation amount of the temperature load of the user during the outdoor work and reducing the body temperature or perspiration amount as early as possible, the risk of heatstroke can be reduced.

The air conditioning system 100 according to the present embodiment may further include an adjusting unit 40, and the adjusting unit 40 may be configured so that the user can change the temperature TR or the time t outputted from the control unit 10. In this way, the air conditioning of the second environment in which the temperature load is reduced can be performed according to the user's desire.

The air conditioning system 100 of the present embodiment may further include a detection unit 50 that detects the case temperature BTs of the user. In this case, the air conditioner 30 may change the reduced temperature TR so that the difference between the reduced temperature TR and the normal temperature is equal to or less than the second predetermined value, or may give an alarm to the user to terminate the exposure in the second environment, when the difference between the case temperature BTs detected by the detecting unit 50 and the target value exceeds the first predetermined value. In this way, heat shock can be alleviated, or overcooling can be prevented.

In the air conditioning system 100 of the present embodiment, the detection unit 60 that detects that the user has entered the second environment may be further included. In this case, the air conditioner 30 may end the air conditioning at the reduced temperature TR when the reduced time t elapses after the detection unit 60 detects that the user has entered the second environment. In this way, the cost required for air conditioning at the reduced temperature TR can be reduced.

(second embodiment)

Human body effective efficacy (Exergy) model related to temperature load

Therefore, when exposed to an extreme temperature environment or moved indoors, the air conditioning control of the opposite temperature environment above or below the normal temperature is temporarily provided for the temperature environment that the mind and body is forced to withstand, specifically, the temperature environment below the normal temperature is provided if the load is due to a hot environment, and the temperature environment above the normal temperature is provided if the load is due to a cold environment, so that the influence of the temperature load can be reduced.

The inventors of the present application have conceived of an invention that uses the theory of human effectiveness to infer thermal stress from a hot environment. As described in detail below, the effective human performance can be calculated from the amount of clothing (clo) and the amount of exercise (met) of the person, and also from environmental information (such as indoor temperature (c), relative humidity (%), wall temperature (c), wind speed (m/s), outside air temperature (c), and outside air humidity (%)), and the temperature and the time of use (the time when the person is exposed to the recovery environment) of the recovery environment (the environment for removing the temperature load accumulated in the hot or cold environment) can be set from the calculation result. The accumulation of human effective energy is included in the following formula related to the balance of human effective energy.

Human effective energy input ] - [ human effective energy consumption ] = [ human effective energy accumulation ] + [ human effective energy output ]

In the above formula, the human effective energy input, human effective energy consumption, human effective energy accumulation and human effective energy output are respectively 1m from each human body ² Parameters of generation, consumption, accumulation and release rate of effective energy obtained from the body surface area. The unit of each parameter is W/m ² 。

The human body effective energy input is mainly effective energy generated in the body and effective energy taken into the body from the outside, and is caused by heat generated by metabolism, inhalation, and radiant heat absorbed by clothing.

The human body effective energy consumption means effective energy consumed in the body due to heat diffusion caused by a temperature difference inside the human body, heat diffusion caused by a temperature difference between the human body and the worn clothing, and interdiffusion of sweat and air generated by a water vapor pressure difference between the human body and the worn clothing.

The accumulation of human effective energy refers to the tendency of the accumulation of human effective energy to increase in a hot environment and decrease in a cold environment according to the effective energy accumulated in the body in the surrounding environment.

The human body effective energy output is the effective energy released from the inside to the outside of the body, and is mainly caused by the diffusion of wet air generated after exhalation and sweat evaporation and the radiant heat released by the worn clothes.

Examples of references relating to the effective energy and balance of the human body include "theory of effective energy and environment-what is a design of flow and circulation [ retrofit edition ] (edited by sink Gu Changze)".

Temperature load elimination model constructed by using effective energy accumulation of human body

The temperature load is a heat stress that causes a thermoregulation function to act by a cold and hot stimulus that prevents the human body temperature from being maintained, and is distinguished from heat accumulated in the human body itself. For example, when the body temperature is maintained by heat radiation by perspiration at 30 ℃, even though no more heat is accumulated, the heat stress is not zero, but a load is applied to the body by perspiration or the like. The temperature and utilization time of the recovered environment against such load are calculated in the following manner.

First, the thermal stress (first temperature load) to which the subject person is subjected from the environment is calculated as follows. It is known from, for example, the above-mentioned references that with environmental information as input, the effective energy accumulated in the human body per unit time in the deep part can be calculated as a function of the exposure time t to the environment. Based on the simulation result obtained based on this knowledge, in the present disclosure, the change in the deep human body effective energy total accumulation ST (t) with respect to the residence time t at each temperature TE to which the user is exposed is obtained as the following approximate expression.

For example, when the model shown in the above reference is used, it means that when a subject in a state of thermal equilibrium in an environment of 26 ℃ is moved to a hot environment of 36 ℃, the effective energy storage amount Δst (Th) of the human body in the deep portion per unit time changes as shown in fig. 8 by the exposure time Th in the hot environment (in fig. 8, the unit of the vertical axis is W/m ² The units of the horizontal axis are minutes). The total accumulated energy ST of the deep human body effective energy is shown in FIG. 9 (in FIG. 9, the vertical axis is given by J/m ² The units of the horizontal axis are minutes).

When the simulation result of fig. 9 is approximated by a Sigmoid function of the exposure time Th in a hot environment, the simulation result can be expressed by the following expression (5).

[ formula 1]

In the formula (5), e is a Napier's constant which is a base of natural logarithm. Th is 0 or more.

Similarly, when a subject in a state of thermal equilibrium in an environment of 26 ℃ is moved to a hot environment of 36 ℃ and then to a recovery environment of 21 ℃ after being exposed to the hot environment for 20 minutes, the total accumulation ST of the deep human body effective energy is changed as shown in fig. 10. In the simulation result of fig. 10, when ST corresponding to time 0:20 (20 minutes) and later is approximated by a Sigmoid function of exposure time Tc in the recovery environment, expression (6) can be obtained.

[ formula 2]

In the formula (6), e is a naphal constant which is a base of natural logarithm. Th is 0 or more.

Here, setting Tc so as to satisfy ST (=st (Th) +st (Tc)) < 0 can be expected to eliminate the accumulation amount of the first temperature load in the hot environment by restoring the accumulation amount of the second temperature load in the environment.

For example, in the case shown in fig. 10, the minimum Tc (utilization time of the recovery environment) satisfying ST < 0 is calculated to be 11.6 minutes by the formula (6).

Thus, the aforementioned approximate expressions concerning various temperatures and exposure times can be set and stored in advance, and the utilization time of the recovery environment can be calculated using these approximate expressions. In the above description, the required use time is determined by selecting the temperature of the recovery environment with respect to the first temperature load, but a more detailed and continuous set temperature and use time may be calculated by using another approximation model.

For the temperature and time of the first temperature load, the temperature TEc of the recovery environment is changed in advance to simulate the effective energy storage of the human body in the deep part of the recovery environmentThe total accumulated amount ST of the product can be used to determine an appropriate exposure time (utilization time). For example, in the case where a subject in a state of thermal equilibrium in an environment of 26 ℃ is exposed to a hot environment of 36 ℃ for 20 minutes, the result of simulating the total accumulated amount ST of TEc accumulated in advance on the deep human body effective energy in the recovery environment is shown in fig. 11 (in fig. 11, the vertical axis is expressed as J/m ² The units of the horizontal axis are minutes). As can be deduced from the results shown in FIG. 11, when TEc is 22 ℃ or lower, ST can be satisfied within 15 minutes of the target time<0。

In the formulas (5) and (6), the method for calculating the effective energy of the human body is not particularly limited. For example, the effective energy may be directly calculated by substituting parameters (such as air temperature and relative humidity) included in the input environmental conditions into a predetermined formula. Alternatively, a predetermined Algorithm (algoritm) may be used to calculate the effective energy from the inputted environmental conditions. Alternatively, a table, database, or the like may be prepared in advance so as to correlate the environmental conditions with the effective energy, and the effective energy may be calculated based on the inputted environmental conditions.

Model items related to the user, such as metabolic amounts and exercise amounts, included in the effective performance model may be estimated from physiological information (skin temperature, perspiration, heart beat, blood flow, etc.) of the person.

In the above-described calculation example, the calculation method of the temperature and the utilization time of the recovery environment (low-temperature environment) against the hot environment was described, but the temperature and the utilization time of the recovery environment (high-temperature environment) against the cold environment may be calculated by simulating the temperature and the exposure time of the temperature load in advance and constructing a model type.

Temperature load management device

Fig. 12 is a block diagram of an air conditioning system 100 including the temperature load management device 20 according to the second embodiment. The temperature load management device 20 of the present embodiment is used when exposing the user to a second environment (recovery environment) for reducing a temperature load (first temperature load) accumulated in the user in a first environment (hot environment, cold environment, or the like).

As shown in fig. 12, the temperature load management device 20 mainly includes a control unit 10. The control unit 10 controls the restoration environment by the air conditioning device 30 described later based on the physiological information of the user, or notifies the user of the time (use time) at which the exposure in the restoration environment is completed.

The physiological information is not particularly limited, and may be at least one of a metabolic rate, a skin temperature, a deep temperature, a perspiration rate, a blood vessel diameter, a blood flow rate, a heart rate fluctuation, and a respiratory rate, for example.

The control target of the recovery environment is not particularly limited, and may be at least one of temperature, humidity, radiation temperature, and air flow, for example.

The temperature load management device 20 includes a microcomputer or the like, and executes a program by the computer to perform the function of the control unit 10, that is, the temperature load management method of the present embodiment. The computer includes a processor operating according to a program as a main hardware structure. The type of the processor is not particularly limited as long as the processor can realize the functions by executing the program, and may be configured by one or more electronic circuits including a semiconductor Integrated Circuit (IC) or LSI (large scale integration; large-scale integrated circuit), for example. The plurality of electronic circuits may be integrated on one chip or may be provided on a plurality of chips. The plurality of chips may be integrated in one device or may be dispersed in a plurality of devices. The program is stored in a non-transitory storage medium such as a computer-readable ROM, an optical disk, a hard disk drive, or the like. The program may be stored in advance in a storage medium, or may be supplied to the storage medium via a wide area communication network including a network or the like.

The temperature load management device 20 may also include a sensor 11 that detects physiological information of the user. The sensor 11 may be, for example, a bracelet-type sensor worn by a user or a sensor that measures body temperatures at a plurality of locations. Instead of the temperature load management device 20 including the sensor 11, the physiological information of the user may be detected by a detection device configured separately from the temperature load management device 20, and the detected physiological information may be transmitted to the temperature load management device 20.

The temperature load management device 20 may further include a storage unit that stores physiological information of the user and the like. In the case where the temperature load management device 20 includes a storage unit, a recording medium such as a RAM or the like that can be read from and written to by a computer can be used as the storage unit.

The temperature load management device 20 may further include an input unit or a display unit for inputting necessary information, outputting the temperature of the recovery environment, the utilization time, and the like. In the case where the temperature load management device 20 includes an input unit, for example, a keyboard, a mouse, a touch panel, or the like can be used as the input unit. In the case where the temperature load management device 20 includes a display unit, a monitor capable of displaying an image, such as a CRT or a liquid crystal display, may be used as the display unit.

The temperature load management device 20 may further include a measurement unit that measures an outside air temperature that is a temperature of a hot environment, a cold environment, or the like. In the case where the temperature load management device 20 includes a measurement unit, the measurement unit may be a temperature sensor carried by a user, or may be a temperature sensor provided in a plurality of places (a room, a public place, an outdoor place, or the like). In the latter case, the temperature around the user is calculated from the temperature history data measured by the temperature sensors provided at the plurality of locations and the movement history data of the user. The movement history data of the user may be stored in advance, or may be input by the user as appropriate or according to the plan setting of the day. As the outside air temperature, the temperature load management device 20 may use outside air temperature information obtained from a network such as an amas.

The installation form of the temperature load management device 20 is not particularly limited, and may be installed on a remote controller of an air conditioner (air conditioner) 30, which will be described later, for example. In this case, the temperature load management device 20 may be configured by a microcomputer, a memory, a touch panel, or the like mounted on a remote controller.

In the temperature load management device 20, the control unit 10 may control the recovery environment or notify the recovery environment of the time of use in combination with the amount of accumulation of the first human body effective energy accumulated by the user under the first temperature load.

In the temperature load management device 20, the control unit 10 may set the temperature or the use time of the recovery environment based on the accumulation amount of the first human body effective energy and based on the accumulation amount of the second human body effective energy accumulated at a second temperature load opposite to the first temperature load, which is required to cancel the accumulation amount of the first human body effective energy. In this case, the temperature and the utilization time of the recovery environment may be calculated from the model expression using the effective energy accumulated in the human body, which is expressed by the expressions (5) and (6).

Air conditioning system structure

As shown in fig. 12, the air conditioning system 100 may be constituted by the temperature load management device 20 and the air conditioning device 30. The air conditioner 30 adjusts the restoration environment based on the temperature of the restoration environment, the use time, and the like set by the control unit 10 of the temperature load management device 20.

In the air conditioning system 100, the air conditioning control by the temperature load management device 20 may be performed mainly when the air temperature (the outside air temperature is, for example, 31 ℃ or higher in summer and the outside air temperature is, for example, 10 ℃ or lower in winter) is subjected to a strong temperature load from a hot environment or a cold environment. On the other hand, in the range of the outside air temperature of about 20 to 30 ℃, air conditioning control at a gentle temperature gradient may be performed around the normal temperature (summer: 25 to 28 ℃). In the range of about 10 to 20℃outside air temperature, air conditioning control at a gentle temperature gradient may be performed around the normal temperature (18 to 22℃in winter).

The air conditioning system 100 may further include an adjusting unit 40, and the adjusting unit 40 may be configured so that a user can change the temperature of the recovery environment, the use time, and the like set by the control unit 10. In other words, the user may manually change the temperature of the recovery environment or the utilization time to a specific value through a remote controller or the like of the air conditioner 30.

The air conditioning system 100 may further include a measuring device (sensor) such as an extreme ambient temperature (outside air temperature) that causes a load on the user. For example, the outside air temperature and the room temperature (the temperature around the user) may be measured by sensors, and the control unit 10 may set the temperature of the recovery environment, the utilization time, and the like using the measured information, and the air conditioning device 30 may supply cool air or warm air to the recovery environment based on the set values.

The air conditioning system 100 may be configured as a closed indoor air conditioning system that controls the temperature of the entire room, such as a restroom. By means of such a rest room, people from outdoors on a very hot day (a very cold day) can reduce the temperature load.

The air conditioning system 100 may be configured as an open type air conditioning system that controls the temperature of a local space in a room, for example, by locally supplying cool air or warm air from a wall of an inlet.

When the air conditioning system 100 is configured as an indoor/outdoor open type air conditioning system, it is necessary to supply air having a state substantially different from that of the air at the use place to the user. In this case, the air conditioning control may be performed using only the surrounding environment of the user as the recovery environment. Therefore, in order to enhance the local air conditioning effect, it is also possible to blow air vertically downward from the air blowing port provided above the use site toward the head of the user, or blow air horizontally from the air blowing port provided at the side of the use site toward the front of the user.

In the open air conditioning system 100, it is necessary to supply air having a temperature greatly different from the outside air temperature. Therefore, if the open type air conditioning system 100 is operated at all times, the cost increases, and therefore, when the object sensor or the like detects that the user has approached the air outlet of the air conditioning apparatus 30, the air conditioning system 100 may be automatically operated. In this case, when the air conditioning system 100 is not in operation, a certain amount of cool air or warm air can be circulated in the air conditioning device 30, so that the cost of temperature control can be reduced, and the cool air or warm air can be immediately supplied when in operation.

The temperature difference between the target temperature (temperature of the recovery environment) and the load temperature (e.g., outside air temperature) of the air conditioning control of the air conditioning system 100 is large, but the utilization time of the recovery environment is limited to, for example, about 5 minutes to 15 minutes. Therefore, it is effective to reduce the cost to perform the temperature adjustment in a short time at a minimum. To achieve this, for example, the air conditioning system 100 may be remotely operated via a network. Specifically, the restoration environment in the room or the like may be quickly adjusted to the target temperature in a short time in conjunction with the predetermined time of entering the room by the user set by the remote operation.

The air conditioning system 100 may further include a detection part 60, which is an object sensor or the like that detects that the user has entered the room or the like to restore the environment. In this case, the air conditioning system 100 may perform the air conditioning control by the temperature load management device 20 only when the detection unit 60 detects that the user has entered the recovery environment. The air conditioner 30 may end the air conditioning by the temperature load management device 20 when the detection unit 60 detects that the use time set by the temperature load management device 20 has elapsed after the user has entered the recovery environment. For example, after the use time (for example, 10 to 15 minutes) set by the temperature load management device after the entrance of the person is detected by the object sensor or the like in the vicinity of the predetermined entrance time set by the remote operation, the temperature of the recovered environment may be automatically returned to an appropriate temperature (for example, about 26 to 28 ℃).

Effects of the second embodiment

The temperature load management device 20 of the present embodiment is used when exposing a user to a second environment (i.e., a recovery environment) for removing a first temperature load accumulated in a first environment (a hot environment, a cold environment, or the like). The temperature load management device 20 mainly includes a control unit 10. The control unit 10 controls the restoration environment based on the physiological information of the user, or notifies the user of the point of time (i.e., utilization time) at which the exposure in the restoration environment is completed.

According to the temperature load management device 20 of the present embodiment, control of the recovery environment for removing the first temperature load accumulated in the first environment or notification of the use time of the recovery environment is performed based on the physiological information of the user. Therefore, the temperature of the recovery environment, the utilization time, and the like can be set according to the user. Therefore, diseases caused by heat stress such as heatstroke and the like can be prevented.

In the temperature load management device 20 of the present embodiment, the control unit 10 may control the recovery environment or notify the recovery environment of the time of use in combination with the amount of accumulation of the first human body effective energy accumulated by the user under the first temperature load. For example, in a user who has accumulated a hot load in a hot environment, control of the recovery environment or the like may be performed in combination with the accumulation amount of the first human body effective energy accumulated due to the hot load. In this way, the user can use the recovery environment more appropriately.

In the temperature load management device 20 of the present embodiment, the control unit 10 may set the temperature or the use time of the recovery environment based on the accumulation amount of the first human body effective energy and the accumulation amount of the second human body effective energy accumulated under the second temperature load required to cancel the accumulation of the first human body effective energy by the second temperature load opposite to the first temperature load. Thus, for example, the amount of accumulation of the first human body effective energy accumulated in the user under the hot environment and the amount of accumulation of the second human body effective energy accumulated under the cold load, which are required to cancel the amount of accumulation of the first human body effective energy accumulated under the hot load, are obtained, and the temperature and the use time of the recovery environment appropriate for the user can be set based on the amounts of accumulation of the human body effective energy.

The temperature load management device 20 of the present embodiment may further include a sensor 11 for detecting physiological information of the user. In this way, the physiological information of the user detected by the sensor 11 can be used to control the restoration environment and the like.

In the temperature load management device 20 of the present embodiment, the sensor 11 may be a bracelet-type sensor worn by a user or a sensor that measures body temperatures of a plurality of locations. In this way, physiological information of the user, such as perspiration amount, heart rate, and the like, can be easily detected.

In the temperature load management device 20 of the present embodiment, the physiological information may be at least one of a metabolic rate, a skin temperature, a deep temperature, a perspiration rate, a blood vessel diameter, a blood flow rate, a heart rate fluctuation, and a respiratory rate. Thus, physiological information related to the temperature load accumulated on the user can be used.

In the temperature load management device 20 of the present embodiment, the controlled object of the restoration environment may be at least one of temperature, humidity, radiation temperature, and air flow. Thus, the temperature load of the user can be removed by controlling the recovery environment.

(other embodiments)

In the first embodiment, the temperature load reduction model represented by the formulas (1) to (3) is used. However, the temperature load reduction model is not particularly limited as long as it is a model describing the interrelation between the case temperature BTs, the load temperature TL, the reduction temperature TR, and the reduction time t.

In the foregoing second embodiment, the temperature load management device 20 sets the temperature and the use time of the recovery environment according to the effective energy accumulated in the human body of the user. However, the temperature load management device 20 may correct the temperature or the utilization time of the recovery environment according to other indexes based on the physiological information of the user. For example, other parameters related to the degree of expansion and contraction of the blood vessel of the user, parameters indicating the balance between the sympathetic nerve and the parasympathetic nerve, and the like may be used. As an example of such a parameter, LF/HF, which is a ratio of a Low Frequency (LF) component to a High Frequency (HF) component of a fluctuation in the respiration or heartbeat of the user, may be used. The ratio LF/HF is related to the degree of vasodilation and contraction of the blood vessel. In this case, the temperature load management device 20 may acquire the LF/HF value using, for example, a device that measures the pulse wave of the user.

For example, when the user subjected to the temperature load caused by the hot environment is exposed to the cold recovery environment and the temperature load is removed, the temperature load management device 20 may end the exposure of the user to the recovery environment when detecting that the blood flow of the peripheral blood vessel of the user's hand or the like has fallen below a predetermined value.

In the second embodiment, the air conditioning system 100 is constituted by the temperature load management device 20 and the air conditioning device 30, and the temperature load management device 20 controls the recovery environment by the air conditioning device 30. However, instead, the temperature load management device 20 itself may include an air conditioning function, and the restoration environment may be controlled by the function.
