Description

The present invention relates to an emergency venue cooling system for cooling an emergency venue such as an outdoor event venue or a shelter, and a method for cooling the emergency venue.

In recent years, due to the effects of global warming, etc., the heat tends to be extremely hot in the summer, especially in the summer, such as outdoor event venues, shelters in the event of a disaster, and work sites where various work must be carried out under high temperatures. At emergency venues where air conditioners are not permanently installed, heat stroke is at stake. Therefore, it is required to develop a cooling device specialized for an outdoor event venue, a shelter in the event of a disaster, and an emergency venue such as a work site under high temperature.

Even if a shelter in the event of a disaster is defined, it may not be possible to specify when, where, and what kind of disaster will occur, so it may not be possible to specify where the shelter will be, including the timing. In addition, the event venue and work site may be decided suddenly. In such emergency venues, in many cases, due to various physical restrictions on the installation location such as lack of power supply equipment, it is required to be able to flexibly change the installation location according to the needs of air-conditioning users. The usage time and period of the air conditioner in the emergency venue is often relatively short for outdoor events, but it may be necessary for a long period of time at evacuation shelters and work sites in the event of a disaster.

Therefore, examples of cooling devices include package-type air conditioners and large-capacity spot coolers. However, package-type air conditioners require the installation of refrigerant pipes, cooling water pipes, and drain pipes, and are premised on permanent installation. Therefore, it cannot be said that it is suitable for installation in an emergency venue. In addition, when installing a spot cooler, in the case of a separate type that separates the installation location of the condenser and the installation location of the evaporator, it is necessary to install a refrigerant pipe, so it is an emergency installation like the package type air conditioner. It cannot be said that it is suitable for installation at the venue. In the case of an integrated type in which the condenser and evaporator are integrated, the installation location can be changed flexibly, but in the emergency venue, the heat exhausted by the condenser is also performed in the venue, so the entire venue is cooled. Will be hindered.

In this way, in the emergency venue, the cooling device that uses the refrigerant and the secondary refrigerant such as brine requires the construction of the refrigerant piping when installing or relocating, and also discharges according to the cooling. With heat, the waste heat becomes a problem. In addition, although it is assumed that there is no power supply facility in the emergency venue, there is also a problem that a huge amount of electric power is required in the emergency venue and a problem of noise due to cooling. Therefore, in order to cool the emergency venue, it is conceivable to exhaust heat in a place different from the emergency venue. For example, the heat storage material in the heat storage tank is stored in a predetermined place during a time when power consumption is low, such as at night, and the air is cooled in a place different from the place where the heat is stored in the time when cooling is required. Can be considered.

Conventionally, as this type of cooling system, as disclosed in Patent Document 1, water contained in an ice heat storage tank and cold ice water are sent to the upper part of a capillary washer provided on the upper part of the apparatus to deliver the water. After sprinkling water, there is one equipped with a temporary cooling device that returns to the ice heat storage tank and sends indoor air to the capillary washer to blow out the cold air that has passed through the capillary washer into the room.

Further, as disclosed in Patent Document 2, the cooler and the indoor unit are connected at a connection portion, and the primary refrigerant cooled by the cooling portion of the cooler is passed through the primary refrigerant circulation path to the indoor unit. The water in the heat storage tank is frozen to generate ice, the indoor unit is separated from the cooler at the connection part, and then only the indoor unit is moved to the desired cooling location by the casters. In the indoor unit, the secondary refrigerant is circulated in the secondary refrigerant circulation path connecting the condenser and the evaporator provided in the heat storage tank where ice is stored, and the high temperature air in the room is sent to the evaporator. There is a combination of a cooler and an indoor unit that cools by touching it and returning it to the room as cold air.

However, the above-mentioned method has the following problems.

In the above-mentioned temporary cooling device, since cooling is performed using the heat of fusion of ice, it is inconvenient because it is necessary to discharge water from the ice heat storage tank and refill the ice water each time it is used. And because it is downsized, the cooling capacity is small, and it is very troublesome to procure a large amount of ice on site, so it is not suitable for upsizing.

Further, in the above-mentioned combination of the cooler and the indoor unit, the indoor unit can be moved only within a very limited range where the indoor unit can be moved by casters, and electric power is required to operate the fan. , I couldn't cool in a place without power. Since the cooling unit is a heat pipe system, there is a restriction that the heat radiation unit must be located above the heat receiving unit, and the entire device becomes complicated and large in principle due to the heat pipe. Moreover, it is impossible to separate the heat storage unit and the evaporator for air cooling. Further, when the heat radiating portion is inside the ice of the heat storage tank, the ice that comes into contact with the surface of the heat radiating portion starts to thaw and becomes water. Water in that state has a poor heat transfer rate and is unlikely to generate convection, so the heat dissipation efficiency of the heat dissipation part is poor, and it is not suitable for large-capacity cooling. Even if there is a heat dissipation part in the cold water, the cold water stirring function is not equipped and the heat dissipation efficiency is poor.

Furthermore, the conventional cooling system was always available by the operator of the emergency venue, but the system is required only for a few weeks to two months in the summer, so from the viewpoint of expenses and labor costs, etc. Therefore, the burden was heavy, it was inefficient, and it was difficult to spread.

(First embodiment: Emergency venue cooling system 100)

FIG. 1 shows a main part of an emergency venue cooling system 100 (not shown) according to the first embodiment of the present invention, and the emergency venue cooling system 100 cools air during cooling operation and sends out heat storage type cooling. The device 1, the brine cooling / refrigerating device 2 for cooling the brine B supplied to the heat storage type cooling device 1, and the heat storage type cooling device 1 are transported between the installation location of the brine cooling / refrigerating device 2 and a desired emergency venue. It is provided with a transporting means (not shown) for carrying the heat storage type cooling device 1 and a lifting means (not shown) for mounting the heat storage type cooling device 1 on the transporting means and unloading the heat storage type cooling device 1 from the transporting means. In this embodiment, for example, a truck is used as a transporting means, and a crane provided on the truck is used as a lifting means.
(Heat storage type cooling device 1)

The heat storage type cooling device 1 includes a heat storage tank 3 that houses ice I as a heat storage material, an ice generation heat exchanger 4 arranged in the heat storage tank 3, and a brine flow that leads to the ice generation heat exchanger 4. An inflow pipe 5 having an inlet 5a, an exhaust pipe 6 having a brine discharge port 6a leading to an ice heat exchanger 4, a fan coil unit 7 that cools air taken in from the environment and supplies it to the environment, and cold water circulation. A chilled water circulation path 10 having a pump 17, a chilled water circulation pump 17, and a battery 8 for supplying operating power to a fan coil unit 7 are provided. As shown in FIG. 2, the heat storage type cooling device 1 further has a housing 9 having a lifting mechanism 9e, and has a heat storage tank 3, an inflow pipe line 5, a discharge pipe line 6, a blower 13, and a fan coil unit. 7. The battery 8 is housed in the housing 9.
(Housing 9)

In the case of this embodiment, the housing 9 includes a substrate 9a having a substantially rectangular shape when viewed from above, and a machine frame having columns 9b and beams 9c erected at the four corners of the substrate 9a. Wheels 9d are provided on the substrate 9a, and the heat storage type cooling device 1 can easily move on the ground or the ground G via the wheels 9d, so that the installation location is changed in the emergency venue. It is convenient for you. Further, it is preferable to use casters with brakes as the wheels 9d. Further, since the fan coil unit having a relatively small weight is arranged on the upper side of the heat storage tank 3 having a large weight, the stability of the housing 9 is good and it is easy to increase the size of the heat storage tank 3. Therefore, it is convenient to obtain a heat storage type cooling device 1 having a small occupied area and a large cooling capacity. Even if the device or the like housed in the housing 9 protrudes from the side surface or the like of the housing 9, the device is assumed to be housed in the housing 9 if it can be moved together with the housing 9.
(Freight mechanism, transportation means)

The lifting mechanism 9e is an eyebolt fixed to the upper part of the housing 9 in this embodiment. Since a crane is used as the lifting means, in order to lift the heat storage type cooling device 1, a sling extending from the hook of the crane is connected to the eyebolt 9e using a shackle, and then the sling is lifted by the crane and lowered to the required position. There is a gap between the lower surface of the substrate 9a and the ground G. Therefore, a forklift may be used as the lifting means, and the substrate 9a having a gap between the ground G and the fork of the forklift may be used as a lifting mechanism for engaging the fork of the forklift. This lifting mechanism can vary in various ways depending on the mode of the lifting means. Further, the heat storage type cooling device 1 may be able to move between the installation location of the brine cooling / refrigerating device 2 and the emergency venue by the wheels 9d provided in the housing 9.
(Adjuster 11)

The adjuster 11 is composed of a level and four bolts 11a arranged near the four corners of the substrate 9a of the housing 9, and each bolt 11a is screwed into the substrate 9a with its tip facing the ground. While looking at the level, turn the necessary bolt 11a of the adjuster 11 and adjust the amount of protrusion of the bolt 11a from the substrate 9a so that the upper surface of the substrate 9a of the heat storage type cooling device 1 becomes horizontal, that is, heat storage. The vertical central axis of the tank 3 can be adjusted to be vertical.
(Heat storage tank 3)

The heat storage tank 3 is heat-insulated, and water W is supplied to the heat storage tank 3 from a water supply line 14 separably connected to the water source in advance. A float switch 15 for detecting the water level is provided in the heat storage tank 3, and when the heat storage tank 3 reaches a predetermined water level, the supply of water W is automatically stopped. When the supply of water W into the heat storage tank 3 is completed, the water supply line 14 is disconnected from the water source. The water W may be supplied directly to the heat storage tank 3 from an external water source, for example, via a hose.

At the time of storing cold air in the heat storage tank 3, that is, at the time of ice making, the brine B cooled by the brine cooling / freezing device 2 can be supplied to the ice generation heat exchanger 4 through the inflow pipeline 5, and receives the supply of the brine B. The ice-generating heat exchanger 4 can turn the water W into ice I by allowing the brine B to absorb heat from the water W around it. The brine B that has absorbed heat from the water W by passing through the ice generation heat exchanger 4 is sent out to the brine cooling / refrigerating apparatus 2 from the brine discharge port 6a through the discharge pipe 6. When the supply of the brine B to the ice generation heat exchanger 4 is stopped, the ice I in the heat storage tank 3 melts, and in the heat storage tank 3, the heat of fusion of the ice I generated by the ice generation heat exchanger 4 melts. Cold water W1 is generated due to the above. That is, when the ice I melts, it takes heat of fusion from the surrounding water W, thereby producing cold water W1 having a temperature close to the melting point of water, and this cold water W1 accumulates in the lower part of the heat storage tank 3.
(Cold water circulation path 10)

The cold water circulation passage 10 includes a cold water delivery pipe 16, a cold water delivery pipe 18, a cold water recovery pipe 20, and a sprinkler pipe 19 provided in the lower part of the heat storage tank 3. The cold water circulation pump 17 is provided between the cold water delivery pipe line 16 and the cold water delivery pipe line 18. The chilled water circulation passage 10 sucks the chilled water W1 in the heat storage tank 3 through the chilled water delivery pipe 16 by a brine circulation pump and discharges the chilled water W1 from the heat storage tank 3 to the heat for air cooling. While supplying to the exchanger 12, the return chilled water W2 generated by heat exchange between the chilled water W1 and the air in the air cooling heat exchanger 12 is returned to the heat storage tank 3.

At the inlet of the cold water W1 of the cold water delivery pipe 16, for example, ice I in consideration of the flow of water W in the heat storage tank 3 so that the ice I in the heat storage tank 3 melts as evenly as possible from the surroundings thereof. It can be placed so that it is located directly below. The sprinkler pipe 19 is provided at a position lower than the water surface of the water W housed in the heat storage tank 3 and higher than the ice generation heat exchanger 4 of the heat storage tank 3, and the heat exchange is performed by the air cooling heat exchanger 12. The finished return chilled water W2 is supplied to the sprinkler pipe 19 through the chilled water recovery pipe 20, and is ejected from the sprinkler pipe 19 in a shower shape.

If the supply of brine B to the ice-generating heat exchanger 4 is continued during ice making, the water W around the ice-forming heat exchanger 4 becomes ice I, and the ice-forming heat exchanger 4 becomes ice over time. A lump of ice I grows in the center, and the inside of the heat storage tank 3 becomes a state in which cold water W1 and ice I coexist. When the time further elapses, all the water W in the heat storage tank 3 freezes, so that the cold water W1 is supplied to the air cooling heat exchanger 12 or the water W after the heat exchange is ejected from the sprinkler pipe 19. You will not be able to. Therefore, it is desirable that the filling rate of ice I, which means the ratio of ice I to water W and ice I mixed in the heat storage tank 3, is around 70 to 80%. Then, when the water W becomes ice I, the volume increases, so that the water level in the heat storage tank 3 rises. Therefore, a float switch 21 for detecting the rise in the water level is provided in the heat storage tank 3, and when the filling rate of ice I reaches a required value, the float switch 21 operates, whereby the heat exchanger 4 for ice generation is operated. The brine cooling / refrigerating apparatus 2 is instructed to stop the supply of the brine B.
(Thermostat 23 and stirring pump 22)

As the cooling operation is performed, the ice I melts and the amount of stored ice in the heat storage tank 3 decreases, so that the contact area between the ice I and the cold water W1 becomes smaller, which causes a decrease in heat exchange efficiency, and the heat storage tank 3 The temperature of the cold water W1 at the outlet tends to rise. Further, if the re-storing ice operation is restarted with the ice remaining in the heat storage tank 3, the ice is formed into strain, which causes a decrease in the heat exchange efficiency at the time of melting the ice, which may lead to damage to the heat exchanger 4 for ice generation. .. Therefore, in order to increase the heat exchange efficiency by stirring the water W in the heat storage tank 3 to lower the temperature of the cold water W1 at the outlet of the heat storage tank 3 and to completely melt the ice I, the lower part in the heat storage tank 3 is used. Is provided with a stirring pump 22 for stirring the water W in the heat storage tank 3, and a thermostat 23 is provided in the cold water delivery pipe line 16 for supplying the water W in the heat storage tank 3 to the fan coil unit 7. It is provided. During the cooling operation of the heat storage type cooling device 1, the temperature of the cold water W1 in the cold water delivery pipe line 16 detected by the thermostat 23 is higher than the predetermined temperature set to prevent the heat exchange efficiency between the ice I and the cold water W1 from deteriorating. Then, the stirring pump 22 operates to stir the water W in the heat storage tank 3.
(Drain water discharge mechanism)

Below the air cooling heat exchanger 12, a drain pan 24 that receives the drain D generated in the air cooling heat exchanger 12 during the cooling operation is provided. The drain D received by the drain pan 24 is supplied to the drain pump 26 through the pipeline 25, and is discharged to the outside by the drain pump 26. The drain D may be discharged by using gravity or the like without providing the drain pump 26.

(Business form of emergency venue cooling system)

It is considered that the emergency venue cooling system 100, 200, 300, 400 will be required for several weeks to two months in the summer. For this reason, regardless of whether the operator who desires air conditioning is a private company that operates an outdoor event venue, or a local government or public institution that operates a shelter in the event of a disaster, the operator of the emergency venue is the relevant operator. It is uneconomical to have a system on hand because of inefficiencies such as expenses and labor costs.

Therefore, the heat storage type cooling device 1, the brine cooling / refrigerating device 2, the transporting means, and the lifting means may be operated by the operator who operates the emergency venue in the rental or leasing business form. It may be operated by a business operator other than the operator who operates the emergency venue. Since another operator owns the heat storage type cooling device 1, the brine cooling / refrigerating device 2, the transporting means, and the lifting means, the operator does not need to keep the emergency venue cooling system on hand. It is possible to provide an emergency venue cooling system that is less burdensome, efficient, and can be widely used. Here, regarding the ownership by another business operator, the heat storage type cooling device 1, the brine cooling / refrigerating device 2, the transporting means, and the lifting means may be owned by different business operators, or the same business. It may be owned by a person, and if it is different from the operator who operates the emergency venue, the benefit of reducing the burden on the operator can be enjoyed.

A heat storage type cooling device 1 (for example, 2000 units) is prepared so that it can be used in the brine cooling / refrigerating device 2, and is installed in the marathon course by means of transporting and lifting means to keep the marathon course itself cool. After the end of the competition, the operators of the emergency venue cooling systems 100, 200, 300, and 400 will collect the heat storage type cooling device 1 from the marathon course by means of transportation and transportation. By doing so, it is possible to hold a marathon event even in the heat of the heat while reducing the cost burden of the marathon event organizer.

In addition, an example of using the emergency venue cooling system 100, 200, 300, 400 in an evacuation center in the event of a disaster will be given. For example, the national government stocks a plurality of heat storage type cooling devices 1 in advance so that they can be used by the brine cooling / refrigerating device 2. Local governments in the affected areas request the countries that own the emergency venue cooling systems 100, 200, 300, and 400 to use the heat storage type cooling device 1. The local government that has received the license for use, or the country that has received the request (or at its own discretion), installs and utilizes the heat storage type cooling device 1 in the evacuation center by means of transportation and transportation. As a result, local governments and the national government can prevent heat stroke in shelters during disasters in the summer while reducing the cost burden.

The emergency venue cooling system and the emergency venue cooling method according to the present invention can be applied to applications for cooling an emergency venue such as an outdoor event venue or a shelter.
