Description

  The present invention relates to a cooling storage unit that wraps and cools an object to be cooled, a body storage unit that stores a body, and a cooling device set thereof. Specifically, cooling that can be temporarily stored in a cold so that perishable foods and dead bodies will not decay in affected areas, developing countries where dry ice is difficult to obtain, or areas where power supply capacity is insufficient. The present invention relates to a storage unit, a body storage unit, and a cooling device set.

  Conventionally, when a person dies during a period of high temperature, a cooling agent such as dry ice has been put in the jar to keep the corpse at a low temperature in order to prevent the decay of the corpse. However, when cooling and storing with dry ice, it is necessary to frequently replace the dry ice, which is troublesome and expensive. In addition, in cases where there was no dry ice production facility, or when it was difficult to obtain dry ice in the event of a disaster, the body could not be cooled and stored with dry ice.

  When a large-scale disaster occurred, a large number of deaths occurred, so the bodies were collected and stored, and it took time to confirm the identity. At that time, if the body was cooled and stored using dry ice, a large amount of dry ice became carbon dioxide, and the morgue was filled with carbon dioxide, hindering the confirmation of the body. On the other hand, when dry ice cannot be used, the body was damaged over time, making it difficult to confirm the body. In addition, when airing dead bodies from a remote location, the use of dry ice is not permitted in order to avoid carbon dioxide filling the plane.

  Not only in affected areas, but also in developing countries where power supply capacity is low, and in developing countries where dry ice cannot be used because there is no dry ice production facility, the method of treatment of corpses has changed from burial to cremation There is also. In such countries, it is necessary to preserve the body in a temporary period until cremation so as not to corrupt. For this reason, there is a need for the development of body preservation technology that uses low power consumption and prevents temporary decay of the body without using dry ice.

  Conventionally, as a technique for cooling and storing a dead body, a technique for attaching an air-conditioning device to a basket, or a technique for cooling the whole body in a refrigerator is known. However, these technologies are not only suitable for transportation due to their large power consumption and large equipment, but they are not suitable for cooling and storing many bodies at the same time when a large-scale disaster occurs. It was. Therefore, various inventions for efficiently cooling and storing the body are disclosed.

  Patent Document 1 discloses a technique of a cooling cloth piece that wraps a body and can be stored for a while. A technique is disclosed in which a body piece is wrapped around a cloth piece using a refrigerant such as chlorofluorocarbon and the refrigerant is circulated in the cloth piece to cool the body. Freon gas and the like are cooled by a refrigerator, circulated in a cooling pipe stretched around a cooling cloth piece via a connecting pipe, and returned to the chiller after circulation. The cooled chlorofluorocarbon gas and the like are circulated in the cooling pipe, so that the body in contact with the cooling pipe is cooled.

  However, depending on the technique of Patent Document 1, since the refrigerant is a gas body and has a small heat capacity, if the refrigerant is not continuously circulated in the cloth piece, the ability to cool the body is insufficient. There is a problem that a cooling machine corresponding to the number of cooling cloth pieces must be provided. Moreover, there also existed the subject that big power consumption was required by operating a cooler continuously. Furthermore, CFCs cause the destruction of the earth's ozone layer and have the problem that their use is restricted.

  Patent Document 2 discloses a technique for storing a corpse that is quiet, can cope with an emergency, and can be stored for a long time at a low cost. Assuming that the body is housed in a bag made of a heat-insulating and air-tight material, an inert cooling gas is injected, the air inside the bag is replaced with an inert cooling gas, and the body is cooled rapidly. Yes.

  In the technique of Patent Document 2, the inert cooling gas used is preferably liquefied carbon dioxide gas or liquefied nitrogen gas. However, even if an inert cooling gas is used, there is a problem that it is difficult to cool the body even if the air in the bag can be replaced with a cooled gas because of its small heat capacity. In addition, when a large number of bodies are placed indoors, carbon dioxide and nitrogen leaking from the bag drastically lowers the oxygen concentration and makes the surroundings deficient. There was also a problem that became difficult.

  Patent Document 3 discloses a technology of a body cooling apparatus that can cool a body without using dry ice and can be configured in a small size as a whole. The body is a cover frame that covers the body with a gap, and a cooling means that circulates the refrigerant in the cooling pipe by arranging a cooling pipe with a gap between the body and the ceiling facing the body in the cover frame. Provided. It is assumed that the dead body is cooled by the cold air when the refrigerant cooled by the cooling means is circulated in the cooling pipe.

  However, in the technique of Patent Document 3, the cooling unit disposed in the ceiling portion of the cover frame is disposed with a gap between the body and the body. Since cold air easily flows out from the gap, there is a problem that the cooling effect of the corpse is low, and in order to continue cooling the corpse, large power consumption is required. In addition, since the cover frame is large and bulky, there is a problem that it is not suitable for storage and transportation for disasters where a large number of deaths are assumed.

  Patent Document 4 discloses a technology of a cooling device that can be efficiently cooled without causing a cooling failure and can be arranged so as not to stand out. A heat medium such as water or brine is circulated through the heat medium flow path in the flexible cooling sheet, and the heat medium exchanges heat with the refrigerant in the cooling unit. Specifically, the body is covered with a cooling sheet like a blanket, and the cooled heat medium is circulated through the heat medium flow path in the cooling sheet, so that the body in contact with the heat medium flow path is cooled. .

  The technology of Patent Document 4 is a technology for cooling the body by sending cooled water / brine to the heat medium flow path in the cooling sheet in a state where the cooling unit and the cooling sheet are connected. In the case of a deviation, the temperature is detected and an alarm is issued by an alarm device.

  However, in the cooling sheet in which the vinyl chloride sheet of Patent Document 4 is thermally welded and the heat medium path is arranged, the cooling capacity is short because the heat capacity is small, and the cooling sheet laid under the object to be cooled. There is a problem that when the heat medium path is crushed by the weight of the object to be cooled, it does not function. Also, it is assumed that the cooling sheet and the cooling unit are used on a one-to-one basis, and cannot be applied to cooling a large number of cooling sheets, and can be used in a disaster area where a large number of deaths have occurred. There was also a problem that it was difficult.

Patent Document 1: Japanese Utility Model Publication No. 1975-5798 Patent Document 2: Japanese Patent Application Laid-Open No. 1997-286701 Patent Document 3: Japanese Patent Application Laid-Open No. 2004-201770 Patent Document 4: Japanese Patent Application Laid-Open No. 2007-51855

  The problem to be solved by the present invention is to provide a cooling storage means that reliably cools the object to be cooled and has a long cooling time, and a body storage means and cooling device set in which the object to be cooled is a body. Specifically, cold storage means and cooling equipment sets that cover fresh foods, etc., bodies that can cool and store many bodies in developing countries where dry ice is difficult to obtain, and even in disaster-affected areas where power supply capacity is insufficient It is to provide a cooling means and a cooling device set. And a set of cooling devices that are easy to stockpile in preparation for disasters where a large number of deaths are anticipated, and that are easy to support and utilize stored cooling preservation means and body cooling means from non-affected areas to affected areas Is to provide.

  The first aspect of the present invention is a cooling storage means for cooling and storing the object to be cooled, wherein the cooling storage means circulates a refrigerant circulation line for circulating a secondary refrigerant that is in a liquid state in a desired cooling temperature range; And a planar body in which the refrigerant circulation pipe is bent and arranged at a desired interval, and the planar body is provided with a shape holding means for the refrigerant circulation pipe.

  The shape and size of the cooling storage means of the first invention is not limited, and it may be a box body that surrounds and cools it, or a flat body that covers and cools the object. The object to be cooled is not limited to food such as fresh vegetables, dead bodies, and the like. As the secondary refrigerant, an alcohol such as ethanol or methanol, or a refrigerant such as ethylene glycol is preferably in a liquid state in a normal temperature range.

  Specifically, alcohols are in a liquid state at a temperature range of about −100 ° C. to about 60 ° C., and ethylene glycol is in a liquid state at a temperature range of about −10 ° C. to about 200 ° C. Therefore, if the temperature of the object to be cooled is cooled below a desired temperature, there is an effect that it is easy to maintain a low temperature state. On the other hand, salt water may be used as the secondary refrigerant. In the case of seawater, the freezing temperature is about −2 ° C. higher than that of alcohols, but the specific heat capacity is twice as large as that of alcohols. Moreover, if salt is mixed into rainwater to obtain high-concentration salt water, the freezing temperature is lowered to about -20 ° C. When the refrigerant is insufficient in an emergency, seawater or salt water having a high concentration can be used as an alternative refrigerant for the secondary refrigerant.

  The refrigerant circulation line only needs to be a line through which the refrigerant can circulate, and two soft resin sheets are stacked and heat-welded to form a pipe line, a soft resin pipe or a metal pipe Etc. The shape holding means may be in a state where the refrigerant circulation pipe is not crushed. In the case where the refrigerant circulation pipe is formed from a soft resin, it is only necessary to have a shape that is higher than the pipe and that holds the shape so that the refrigerant circulation pipe is not crushed across the pipe. The material and form of the shape holding means are not limited, and may be, for example, a resin material or the same liquid as the secondary refrigerant. When the material of the refrigerant circulation pipe is a metal, the fact that the material is a metal itself is the shape holding means.

  The first planar body may be a flexible sheet or a plate body whose shape is not deformed. For example, in the case of a flexible sheet, a sheet covering a large number of collected vegetables may be used as the first planar body. In the case of a plate body whose shape is not deformed, it is preferable that the plate body is a flat body applied to a bottom plate, a side plate or the like of a box such as a cage for storing the body. Since the refrigerant circulation pipe is formed to be bent and circulated at a desired interval along the first planar body, the object to be cooled is cooled evenly.

  Here, the desired cooling temperature range is not limited as long as the temperature is suitable for cooling and holding the object to be cooled. The desired interval may be appropriately designed according to the object to be cooled, and the object to be cooled can be quickly cooled if the interval between the adjacent refrigerant circulation pipes is reduced, and the amount of the secondary refrigerant if the interval is increased. Can be saved. It is sufficient that the object to be cooled is circulated until the object to be cooled is cooled, and the circulation may be stopped after the object to be cooled is cooled.

  According to the first aspect of the present invention, the refrigerant circulation pipe is not crushed by the weight of the object to be cooled, the secondary refrigerant is circulated in the refrigerant circulation pipe without stagnation, and the object to be cooled is Cooled by the secondary refrigerant. Moreover, since the refrigerant circulation pipe is formed to be bent and circulated at a desired interval along the first planar body, the object to be cooled is cooled evenly.

  The second invention of the present invention is the cooling storage means of the first invention, wherein the cooling storage means covers the object to be cooled, the planar body forming the cooling storage sheet is a soft resin sheet, The refrigerant circulation pipe is made of a soft resin pipe, and the shape holding means is made to have a dimension substantially equal to or larger than the outer diameter of the refrigerant circulation pipe, along the soft resin sheet on the side where the refrigerant circulation pipe is formed. It is characterized by being provided.

  In the second invention, since the first planar body constituting the cooling preservation sheet is a soft resin sheet and the refrigerant circulation pipe is made of a soft resin material, the object to be cooled depends on the shape of the object to be cooled. It is possible to cover the object to be cooled by covering the gap between the cooling storage means and the cooling storage means in a small state. Further, even if the refrigerant circulation pipe is formed from a soft resin material, the shape holding means having a height equal to or higher than the thickness of the refrigerant circulation pipe is provided on the side where the refrigerant circulation pipe is formed. The refrigerant circulation pipe is not crushed even by the weight of the object to be cooled. Furthermore, it is easy to wrap the object to be cooled and can be folded and stored when not in use.

  Here, if the shape maintaining means is a heat insulating layer made of urethane resin, the refrigerant circulation pipe is prevented from being crushed and it is difficult to transfer heat from the outside to the cooling storage means. On the other hand, if the shape holding means is a bag body or the like in which liquid is enclosed, the enclosed liquid can be cooled by the refrigerant in the refrigerant circulation line, and the overall heat capacity of the cooling storage means can be increased.

  According to a third aspect of the present invention, in the cooling storage means of the second aspect, the planar body is a bag body in which the periphery of the soft resin sheet and the second soft resin sheet facing it are thermally welded. The refrigerant circulation pipe is formed on the inner surface side of the bag body, and the shape holding means is configured to inject the liquid material around the refrigerant circulation pipe in the bag body, The refrigerant circulation pipe is formed so as not to be crushed, and the liquid material is heat-exchanged with the secondary refrigerant circulating in the refrigerant circulation pipe to form a tertiary refrigerant, and the object to be cooled is cooled. Yes.

  In the third invention, the refrigerant circulation conduits are arranged in a bag body in which two soft resin sheets face each other and the periphery thereof is thermally welded, and a liquid material is enclosed in the bag body. The shape is maintained so that the pipeline is not crushed. In addition, since the liquid material is a tertiary refrigerant that exchanges heat with the secondary refrigerant that circulates in the refrigerant circulation pipe, the heat capacity of the cooling storage means increases, and the time for maintaining the object to be cooled in the cooled state increases. . Further, even if the secondary refrigerant is extracted after the tertiary refrigerant is cooled, there is an advantageous effect that the cooling storage means can maintain the cooling effect for a long time.

  According to a fourth invention of the present invention, in the cooling storage means of the second or third invention, the hook fastener and the loop fastener are engaged with the opening / closing portion when the object to be cooled is wrapped and cooled, thereby enabling the opening and closing. It features a hook-and-loop fastener.

  According to the fourth invention, the cooling storage means is a cooling storage sheet and includes an openable and closable opening and closing portion, and the opening and closing portion includes the surface fastener, so that the surface can be cooled according to the shape and size of the object to be cooled. By adjusting the position where the fastener is pasted, the gap between the object to be cooled and the cooling storage means can be reduced and wrapped. Since the gap between the object to be cooled and the cooling storage means is small, the object to be cooled can be quickly cooled and the cooling state can be maintained for a long time.

  According to a fifth aspect of the present invention, in the cold storage means of the second or fourth aspect of the invention, there is provided a bag body forming a heat insulating air layer capable of enclosing air along the outer surface side of the cold storage means. It is characterized by having. By providing a heat insulating air layer that forms a bag along the outer surface side of the cooling storage means, the heat insulating property is enhanced, and condensation is less likely to occur, and the ability to maintain the cooled state of the object to be cooled is enhanced.

If it is. When the object to be cooled is a corpse, the cooling temperature of the secondary refrigerant is preferably about −10 ° C., but when the object to be cooled is fresh food, about 0 ° C. is preferable, It only needs to be adjusted. The heat exchanging means includes a secondary refrigerant outlet for sending the secondary refrigerant to the refrigerant circulation line of the cooling storage means, and a secondary refrigerant inlet for returning the secondary refrigerant from the refrigerant circulation pipe of the cooling storage means, The secondary refrigerant cooled by the heat exchange means circulates in the refrigerant circulation pipe of the cooling storage means.

These hydrocarbon refrigerants can be easily compressed by the compressor 95 as compared with conventional alternative chlorofluorocarbons, and the power consumption of the compressor, which accounts for the majority of the power consumption of the cooling device 90, is reduced, reducing the power consumption. Is possible. In particular, when a mixed refrigerant in which ethane, propane, isobutane, and normal butane are mixed is used, power consumption can be reduced by about 30% compared to the case where an alternative chlorofluorocarbon refrigerant is used. . However, the primary refrigerant is not limited to a natural refrigerant and may be an alternative chlorofluorocarbon refrigerant. The secondary refrigerant may be in a liquid state in a desired cooling temperature range, and may be, for example, alcohol or ethylene glycol. However, the secondary refrigerant is not limited thereto, and may be salt water having a high concentration.

  The heat exchanger 92 only needs to be able to exchange heat between the primary refrigerant and the secondary refrigerant evaporated in the evaporator 98 of the refrigeration circuit. For example, if the heat exchanger 92 is a commercially available double-pipe heat exchanger, etc. Good. The conduit through which the secondary refrigerant of the heat exchanger 92 in the cooling device flows is a metal tube having saltwater corrosion resistance. Thus, one cooling device 90 functions as an injection device for injecting the tertiary refrigerant into the bag body 12 and, after injecting the tertiary refrigerant, circulation of the secondary refrigerant for circulating the secondary refrigerant to the refrigerant circulation line 14. It also functions as a device.

  The secondary refrigerant cooled through the heat exchanger 92 is pushed out from the secondary refrigerant outlet by the pump 93 and is injected into the refrigerant circulation line 14 via the refrigerant line 16. The tertiary refrigerant in the bag body 12 is cooled by the secondary refrigerant sent out to the refrigerant circulation pipe 14, thereby cooling the object 13 to be cooled. The secondary refrigerant that has circulated through the cooling preservation sheet 10 and has transmitted heat to the tertiary refrigerant passes through the secondary refrigerant inlet and flows into the heat exchanger 92 again to be cooled. Further, the connecting device 17 between the refrigerant pipe 16 and the refrigerant circulation pipe 14 is provided with an automatic opening / closing valve, and even if the cooling device 90 and the cooling preservation sheet 10 are separated, the leakage of the secondary refrigerant. Is prevented.

  Here, a plurality of specific examples of the shape maintaining means of the refrigerant circulation pipe will be described as Example 2 with reference to FIG. Although the specific example of the shape holding | maintenance means of a (A) figure to the (E) figure is shown in FIG. 2, these are only illustrations and are not limited to this. First, the shape holding means 100 in FIG. 2 (A) has a vinyl resin tube 102 disposed on one side of a vinyl resin sheet 101 on one side, and a solid resin having the same height as the tube between the tubes. A heat insulating mat 103, for example, a urethane resin heat insulating material is provided. Even if an object to be cooled (not shown) is placed on the upper surface of the vinyl resin sheet, the refrigerant circulation pipe made of the vinyl resin pipe 102 is prevented from being crushed.

  In the shape holding means 200 in FIG. 2B, a vinyl resin tube 203 is disposed between two vinyl resin sheets 201 and 202 facing each other, and a space between the vinyl resin sheets 201 and 202 and the tube 203 is provided. Is encapsulated with a liquid material 204 forming a tertiary refrigerant. In the shape holding means 300 in FIG. 2 (C), the interval between the two vinyl resin sheets 201 and 202 facing each other is made larger than the diameter of the vinyl resin tube 203, and between the two vinyl resin sheets. The encapsulated liquid material 204 is used as a shape maintaining means for the refrigerant circulation pipe, and the capacity of the liquid material 204 used as the tertiary refrigerant is increased.

  In the shape holding means 400 in FIG. 2D, the two vinyl resin sheets 402 and 403 in the middle of the four vinyl resin sheets that are stacked facing each other are welded, and the streaks are bent in alternate directions. A liquid material forming a tertiary refrigerant between the outer two vinyl resin sheets 401 and 404 and the inner vinyl resin sheets 402 and 403 by forming a pipe line 405 as a refrigerant circulation pipe. 406 is enclosed. In the shape holding means 500 in FIG. 2 (E), the width of the conduit 405 in FIG. 2 (D) is widened, the capacity of the refrigerant circulation conduit 501 is increased, and the object to be cooled (not shown) is cooled quickly. The shape holding means to be able to do is shown. In any of these embodiments, even if an object to be cooled is placed on the upper surface of the vinyl resin sheet, the refrigerant circulation conduit is not crushed by the effect of the shape holding means.

  In Example 3, the body cooling means 20 provided with the heat insulating mat 21 will be described with reference to FIG. FIG. 3 is a diagram for explaining a state in which the body cooling means 20 is viewed in a perspective view, in which the refrigerant circulation pipe is not shown. The description is omitted and the same applies to the embodiments described later. In the body cooling means 20 of the third embodiment, the cooling storage means 100 in FIG. 2A is disposed below, and the cooling storage means 200 in FIG. 2B is disposed above. The lower and upper cooling storage means are used as body preservation means, and the body 22 is placed on the lower body storage means, and the edge 22 in contact with the lower and upper cooling storage means is provided as a streak along the edge. The zipper 23 is closed.

  Since the lower heat insulating mat 21 functions as a shape maintaining means for the refrigerant circulation pipe, even after the body 24 is placed on the heat insulating mat, the secondary refrigerant is circulated without stagnation in the refrigerant circulation pipe. According to the body cooling means 20 of the third embodiment, the secondary refrigerant may be injected into the bag body 25 of the upper cooling storage means, and then the tertiary refrigerant may be injected. Accordingly, the body can be cooled from below and above, and the upper bag body 25 can cover the body in a light and flexible state, which makes it easy to cool the body.

  In Example 4, with reference to FIG. 4, the body cooling means 30 sealed with the hook_and_loop | surface fastener with which a hook fastener and a loop fastener are engaged is demonstrated. FIG. 4 is a perspective view showing the body cooling means with hook-and-loop fastener. The body cooling means of the fourth embodiment is constituted by any one of the cooling preservation means provided with the shape holding means shown in FIGS. 2 (B) to 2 (D), but is not limited to this. The body cooling means 30 is a rectangular cooling preservation sheet having a width of about 2.5 m and a length of about 2 m, which is superposed in three folds, and hook fasteners are placed on the superposed portion. A hook-and-loop fastener 33 formed to extend in a streak shape is provided so that 31 and the loop fastener 32 are engaged.

  The body cooling means 30 is mounted on the body cooling means 30 substantially in the center, both side edges of the body cooling means 30 are folded back so as to wrap the body 34, and sealed with the hook-and-loop fastener 33. Since the upper and lower edges of the body cooling means 30 are also provided with a surface fastener and sealed, leakage of cold air from the body cooling means 30 is prevented. Since the tertiary refrigerant is injected into the bag body 12 as the shape maintaining means from the inlet 18 of the tertiary refrigerant in advance, the secondary refrigerant is circulated through the refrigerant circulation line without stagnation.

  In Example 5, a body cooling means 40 having a heat insulating air layer on the outside will be described with reference to FIGS. 5 and 6. 5 (A) and FIG. 6 (A) show a state before injecting air into the adiabatic air layer of the body cooling means 40 in a perspective view and a sectional view, and FIG. 5 (B) and FIG. B) The figure shows the state after injecting air into the adiabatic air layer of the body cooling means in a perspective view and a sectional view. FIG. 6C is a cross-sectional view showing a state in which a sheet in which closed cells are arranged is attached to the outer surface of the body cooling means in FIG. 6B.

  First, with reference to FIG. 5 (A) and FIG. 6 (A), the structure of the body cooling means 40 before air is inject | poured into a heat insulation air layer is demonstrated. The cooling device set includes a body cooling means 40, an air pump 41, and a cooling device (not shown) (see FIG. 1). The body 42 is wrapped with the body cooling means 40 (see FIG. 5 (A)), and air is injected into the end of the heat insulating air layer 43 forming the body cooling means by connecting to the air pump 41 to form the heat insulating air layer. An air inlet 47 for inflating is provided. The air inlet 47 is provided with a check valve for preventing leakage of air injected into the body cooling means.

  The body cooling means 40 is configured by superimposing an inner layer 44 in which a refrigerant circulation pipe is disposed and an adiabatic air layer 43 for injecting air to the outer side (FIG. 6A). (See figure). In the inner layer 44, a refrigerant circulation line is formed as in the first embodiment, and the body is cooled. Before the adiabatic air layer 43 swells, the body cooling means 40 is sealed by the hook-and-loop fastener 45, but there is a slight gap 46 between the body cooling means 40 and the body 42, and the refrigerant circulation conduit and the body Is not completely in contact.

  In order to cool the body, first, the body 42 is placed on the body cooling means 40, wrapped in the body cooling means 40 according to the body size of the body 42 so that the gap becomes small, and the hook-and-loop fastener 45 is bonded, The body cooling means 40 is sealed, and air is injected from the air injection port 47 by the air pump 41 to inflate the heat insulating air layer 43 (see FIG. 5B). The order of injecting the tertiary refrigerant and the secondary refrigerant into the dead body cooling means 40 may be either before or after injecting air into the adiabatic air layer 43. However, it is better to inject before injecting air. The shape of the body cooling means 40 is preferable because it is easy to maintain.

  By injecting air into the adiabatic air layer 43 and expanding, the adiabatic air layer 43 becomes an air layer and is insulated, and the cooling performance of the body cooling means 40 is enhanced. Further, the insulating air layer 43 presses the inner layer 44 inward, the inner layer 44 is brought into close contact with the body 42, and the air in the gap is pushed out (see FIG. 5B). The gap between the body cooling means 40 and the body 42 is eliminated (see FIG. 6B).

  Here, with reference to FIG. 6 (C), the body cooling means 50 of another aspect of Example 5 with which the closed cell sheet was provided in the outermost periphery of the body cooling means is demonstrated. In the closed cell sheet 51, independent bubbles having a diameter of 5 mm to 1 cm are formed on one side of the resin sheet, and are attached to the outermost periphery of the body cooling means. In the closed cell sheet, since no gas is convected, the heat insulation performance of the closed cell sheet is easily maintained, condensation is hardly generated on the surface, and the heat insulation performance is further improved.

  In the sixth embodiment, a cooling device set in which a plurality of body cooling means 60 is cooled by one cooling device 90 will be described with reference to FIG. The cooling device set 2 shown in FIG. 7A shows a state in which one body cooling means 60 is connected to one cooling device 90 and other body cooling means are sequentially cooled. In the cooling device set 3 shown in FIG. 7B, a plurality of body cooling means 60 are connected to the refrigerant pipe line 16 extending from one cooling device 90 via a joint member 62, so that a plurality of body cooling means. Is shown in the state of being simultaneously cooled. In the vicinity of the center of each body cooling means, a temperature indicator 61, a thermometer, and the like are disposed, and it is preferable to make it easy to visually recognize from the outside because the temperature management of the plurality of body cooling means becomes easy. Of course, only the vicinity of the temperature indicator 61 or the like may be a transparent material, and the whole may be a transparent material.

  First, the cooling device set 2 will be described with reference to FIG. When the body is cooled, the body cooling means 60 and the cooling device 90 are connected by the connector 17, and the cooled secondary refrigerant is injected into the body cooling means 50. Next, when it is confirmed by the color change of the temperature indicator 61 that the body has reached a desired cooling temperature, the body cooling means 60 and the cooling device 90 are separated. Then, the other body cooling means and the cooling device are connected to the connecting tool, and cooling of the other body is started. This is repeated to cool the plurality of body cooling means. If the temperature of the dead body cooling means 60 becomes higher than the cooling temperature range due to the color change of the temperature indicating material 61 after a lapse of time, the dead body cooling means 60 is again connected to the cooling device by the connecting tool. What is necessary is just to cool.

  Next, the cooling device set 3 will be described with reference to FIG. The refrigerant pipe 16 extending from one cooling device 90 is connected to a plurality of joint members 62, and another refrigerant pipe is connected to the branch port of the joint member. Connected. The number of dead body cooling bodies connected at the same time is not limited, and may be determined according to the cooling capacity of the secondary refrigerant from the cooling device 90. When it is confirmed by the color change of the temperature indicating material 61 that the body cooling means 60 has reached the desired cooling temperature range, the body cooling means 50 is removed from the refrigerant pipe 16, and the uncooled body cooling is performed. The refrigerant pipe 16 is connected to the means 60 or the body cooling means 60 whose temperature is higher than the cooling temperature range. In this way, when a catastrophe occurs, it is possible to cool and store many bodies at the same time.

  Next, the body cooling means included in the bag 70 of Example 7 placed in the body mortuary will be described with reference to FIG. FIG. 8 is a cross-sectional view showing a state in which the corpse is placed on the eaves 70. A body cooling means 71 is provided on the side surface and bottom surface of the bowl 70. The secondary refrigerant is circulated through the refrigerant circulation pipe 72 of the body cooling means 71 to cool the tertiary refrigerant, which is the shape holding means 73 disposed around the refrigerant circulation pipe 72. After the tertiary refrigerant is cooled, the secondary refrigerant is sucked and extracted from the refrigerant circulation line 72, and the flange 70 is cut off from the refrigerant pipe by the connector 17, and only the tertiary refrigerant is used in an independent state. The body is cooled.

Even in a funeral hall where many funerals are held in one place, it is only necessary to provide one cooling device 90 (not shown), and since the cooling device 90 is not driven in a state where the body is placed, noise is generated in the funeral hall. It does not occur. Further, if the tertiary refrigerant is sucked and extracted at the time of extraction, there is an effect that the tertiary refrigerant does not become an obstacle to cremation.
