Description
Technical Field
The utility model relates to an energy storage equipment field especially relates to a marine battery container system with environmental control system.
Background
The box type energy storage unit with the lithium battery arranged in the container is widely applied to land, and with further maturity of battery technology, the box type battery unit can be applied to the field of ships and used as a main power supply or an energy storage device of the ships to realize cleanness of ship power.
To achieve safe and efficient use of the box-type battery unit, attention must first be paid to achieving effective thermal management of the lithium battery: the lithium battery generates a large amount of heat in the charging and discharging processes, and heat exchange needs to be carried out in time to control the temperature of the lithium battery; secondly, the environmental conditions of the lithium battery are controlled, so that the influence on the service life of the battery caused by the over-cooling and over-heating environment of the lithium battery is avoided; finally, a large amount of combustible gas can be released when the lithium battery is out of control due to heat, and the place where the lithium battery is located has the function of emergency purging when the situation occurs, so that the situation that combustion and explosion occur and are difficult to control is avoided.
Compared with land energy storage containers, the battery container for the ship is applied in consideration of the above requirements, and special requirements are further considered in combination with the special application scene of the ship. The arrangement space of the ship is limited, the compactness of the internal arrangement of the battery container is required to be improved as much as possible to realize the purpose of serving as a main power supply, the close arrangement and even the stacking arrangement of a plurality of battery containers are also required to be considered as much as possible so as to carry electric quantity, the auxiliary system and the equipment in the ship battery container occupy as little space as possible, and meanwhile, no outstanding equipment and accessories are required to be arranged outside the container so as not to influence the close arrangement. In addition, different from the situation that the land energy storage container is installed in place and then continuously operates, the ship using the battery container as power usually adopts a battery replacement mode, so the ship battery container also faces the transfer between ships and banks and the storage working condition on the bank (such as a wharf), the battery container does not work in the transfer and storage working conditions, but the container is a closed environment, the internal temperature of the container can be continuously increased due to the radiant heat of the external environment, and the internal environment of the container still needs to be controlled to avoid the external environment (mainly high temperature) from influencing the service life of the battery.
In the prior art, the temperature control of the lithium battery has two means of liquid cooling and air cooling (natural cooling), wherein a liquid cooling system is complex, and the battery is deformed due to long-term use, so that the liquid cooling device is separated from the heat exchange surface of the battery and then loses the cooling effect, and the system is less in application. The air cooling system is usually realized by an industrial air conditioner and an air duct arranged in the energy storage container, and by adopting the air cooling system, the battery can be cooled, and the environment inside the container where the lithium battery is located can be controlled, for example, patent CN 209913535U, CN 211090461U, CN 210838023U, CN 211150627U discloses a system for cooling and controlling the environment by adopting an air conditioner and an energy storage container.
In the prior art, as for an air conditioning system serving a battery container, attention is paid to effectiveness of airflow organization during operation, and an attempt is made to improve air cooling efficiency by arranging heat dissipation air ducts in different forms such as top air supply and air walls (for example, patent CN 210838023U, CN 211150627U). Because the technologies are mostly used for land energy storage containers or the technologies adopt the same scheme as land when being applied to ships, the requirements on the internal and external spaces of the containers and the requirements on transportation and storage in the ship application scene are less considered, and no special technical scheme is provided for coping with the requirements.
In the prior art, an air conditioning system and a ventilation system serving a battery container are generally mutually independent systems, and equipment configuration, arrangement and control systems are generally required to be respectively arranged, do not form an integrated system, and do not have linkage and centralized control functions.
In the prior art, an air conditioner configured for an energy storage container is generally an integrated cabinet air conditioner or a split cabinet air conditioner. If the integrated cabinet air conditioner is of a water-cooling type, cooling water needs to be supplied from the outside, and when no cooling water is supplied from the outside (for example, when a container needs to be transported or stacked and stored in a wharf), an air conditioning system in the container cannot work, which may cause the temperature of the internal environment to rise, and the service life of a battery is affected. Integral type cabinet air conditioner if for the air-cooled, need set up great radiator fan trompil on the container outer wall, this can influence the whole fire behavior of container, easily receives the adverse weather influence simultaneously and leads to normally working. If the integrated air-cooled cabinet machine is operated to control the ambient temperature in the container during transportation or wharf stacking and storage, large power consumption can be generated, and the integrated air-cooled cabinet machine is difficult to realize in the absence of an external power supply.
The integral type cabinet air conditioner is bulky, and it is many to occupy container inner space, influences the density that sets up of group battery. Some technical solutions (for example, patent CN 210838023U) are to save the internal space of the container, and an integrated air conditioner is disposed on the top of the container, resulting in a protrusion outside the container, and thus a stacked arrangement of a plurality of containers cannot be realized.
If a split type cabinet air conditioner is adopted (for example, patent CN 211090461U), the external air conditioner needs to be installed outside the container, and the external container has a protrusion, so that a compact arrangement of multiple containers cannot be realized.
In the prior art, an integrated or split type cabinet air conditioner provided for energy storage containers needs to be provided for each energy storage container respectively with an air conditioner meeting the maximum use condition of the container, and if a plurality of containers are provided but the containers do not run at full load, the total power of the air conditioners is redundant, so that the cost is increased.

Air in the box enters the air inlet air pipe 21 through the air return shutter 23, is sent to the main air pipe 28 through the circulating fan 25 after heat exchange with cold water, and is diffused to the energy storage unit placing area 12 through the air outlet of the main air pipe 28, so that heat dissipation and cooling are achieved. The air flowing through the energy storage unit placing area 12 is heated and then enters the air inlet duct 21 through the air return shutter 23, so that circulation is realized. The amount of cooling air is fed back to the controller 51 by a monitoring signal of the internal temperature sensor 53, and the controller 51 controls the opening of the temperature-controlled three-way valve 306.
Referring to fig. 3, the standby mode includes an external high temperature standby sub-mode and an external low temperature standby sub-mode; when the controller 51 operates the standby mode, the controller 51 obtains an inside temperature T1 inside the container body 11 through the inside temperature sensor 53, and obtains an outside temperature T2 outside the container body 11 through the outside temperature sensor 54, and sets a target temperature T0 inside the container body 11 through the controller 51;
when both the in-box temperature T1 and the out-box temperature T2 are higher than the target temperature T0, the controller 51 operates the external high-temperature standby sub-mode; the controller 51 controls the cold water supply switching valve 304, the cold water return switching valve 305 and the temperature control three-way valve 306 to enable the cold water storage tank 312, the high-temperature cold water supply pipe 309, the cold water coil 308 and the high-temperature cold water return pipe 310 to be communicated; the controller 51 controls the high-temperature cold water circulating pump 311 to be opened, the return air shutter 23 to be opened, the fresh air shutter 24 to be closed, the circulating fan 25 to be operated, the air supply air valve 27 to be opened, the ventilation shutter 29 to be closed, the air exhaust air valve 42 to be closed, the air exhaust fan 43 to be closed and the air exhaust shutter 44 to be closed;
in this state, the cold water system of the system is switched to a high temperature cold water circulation, the high temperature cold water circulation pump 311 is started, and the water in the cold water storage tank 312 is conveyed to the cold water coil 308 to exchange heat with the air, and then returned to the cold water storage tank 312. The air in the container is still internal circulating as in normal operation mode. The temperature of the water in the cold water storage tank 312 is lower than the air temperature, so that the temperature rise of the water can be used for providing a certain amount of cold energy to balance the radiation heat of the external environment to the inside of the container under the working condition, and the temperature inside the container can be maintained within an acceptable range within a certain time.
When the in-box temperature T1 is higher than the target temperature T0 and the out-box temperature T2 is lower than the target temperature T0, the controller 51 operates the external low temperature standby sub-mode; the controller 51 controls the high-temperature cold water circulating pump 311 to be closed, the return air shutter 23 to be closed, the fresh air shutter 24 to be opened, the circulating fan 25 to be operated, the supply air valve 27 to be opened, the ventilation shutter 29 to be opened, the exhaust air valve 42 to be closed, the exhaust fan 43 to be closed and the exhaust shutter 44 to be closed.
In this state, the cold water system of the system stops operating, and the temperature inside the container can be prevented from rising through ventilation because the external environment temperature is low. Outside air enters the air inlet pipe 21, is sent to the main air pipe 28 by the circulating fan 25, is diffused by the main air pipe 28 and then is discharged out of the container through the ventilation shutter 29, and ventilation and cooling of the interior of the container are realized.
Referring to fig. 4, when the controller 51 operates the emergency mode, the controller 51 controls the high temperature cold water circulation pump 311 to stop, the return air louver 23 to close, the fresh air louver 24 to close, the circulation fan 25 to stop, the supply air valve 27 to close, the ventilation louver 29 to open, the suction air valve 42 to open, the purge fan 43 to operate, and the purge louver 44 to open.
In this state, outside air enters the inside of the container through the ventilation louver 29, flows through the storage area of the energy storage unit, then flows to the exhaust air pipe 41 through the main air pipe 28, and is sent to the outside of the container through the air-expelling fan 43, so that forced air expelling is realized to reduce the concentration of combustible gas in the container, and further gas accumulation is prevented from causing fire and explosion.
When the controller 51 operates the fire state mode, the controller 51 controls the cold water supply switching valve 304, the cold water return switching valve 305, and the temperature-controlled three-way valve 306 to be maintained as they are; the controller 51 controls the high temperature cold water circulation pump 311 to stop, the return air louver 23 to close, the fresh air louver 24 to close, the circulation fan 25 to stop, the supply air valve 27 to close, the ventilation louver 29 to close, the suction air valve 42 to remain as it is, the purge fan 43 to stop, and the purge louver 44 to close.
Under this state, the fan and the water pump inside the container body 11 stop running, the valve keeps the original position, and all the shutters are closed, so that the container body 11 is ensured to be in a closed state, and the fire extinguishing effect of the fire extinguishing system is ensured.
The method further comprises the step that the controller 51 adjusts the opening degree of the temperature control three-way valve 306 to the cold water bypass pipe 307 and the cold water coil 308 according to the temperature in the refrigerator and the set required temperature, and further adjusts the amount of water entering the cold water coil 308 to adjust the refrigeration effect.
