Abstract
The invention relates to the field of transportation of predominantly thermally unstable products such as perishable food products, medicines, biological materials, the storage of which requires cooling or freezing thereof, and the transportation of which requires the maintenance of predetermined temperatures within a heat-insulated space of a vehicle. The invention provides a vehicle for transporting the thermally unstable products and a method for transportation of thermally unstable products.
Description
The invention relates to the field of transportation
of predominantly thermally unstable products such as perishable food products,
medicines, biological materials, the storage of which requires cooling or
freezing thereof, and the transportation of which requires the maintenance of
predetermined temperatures within a heat-insulated space of a vehicle.
Currently, transportation is a strategically
important element in the general life-support system for both big human
settlements and individual organizations, and individual consumers of products
being transported. In particular, timely delivery of fresh food products,
medicines or biological materials is important; and upon transportation all
storage conditions for the above-listed thermally unstable products should be
observed in order to preserve their optimal quality. Based on the foregoing,
the important aspect is to reduce the cost of transportations because of their
great demand and to increase the environmental safety of the transportation
process.
In order to solve the above problems liquefied
natural gas (LNG) has become of widespread use as a fuel for internal
combustion engines which causes significant advantages compared to conventional
fuels of petroleum origin. Against the background of the environmental
regulations, there is a growing tendency in the developed countries towards gas
consumption as a fuel, for its use causes much less damage to the environment
compared to traditional fuels that is mainly associated with the exhaust gas
contents.
The advantages of the natural gas being used as a
fuel for vehicles lie in that the cost of natural gas is twice lower compared
to the cost of traditional fuel which makes the cost-effectiveness of natural
gas. Likewise, due to natural gas being used as a fuel, the service life of an
engine becomes three times longer, its maintenance costs being significantly
reduced. Using natural gas as a fuel reduces oil consumption twice; the
specific fuel mass consumption is reduced as well (due to a higher combustion
heat), and there is no need for radical engine reconstruction. Besides,
nowadays production of gas power systems for vehicle engines is quite
widespread.
In connection with the above advantages of the
liquefied natural gas being used as a fuel, recently a widespread application
has been gained by the liquefied natural gas refrigeration systems for
heat-insulated cargo compartments, which systems being based on the heat
content of said gas, such as methane, under conditions when its aggregate state
(liquid-gas) is changed before it is supplied into the vehicle engine. Though
the use of such refrigeration systems is almost impossible at all stages of
thermally unstable product transportation from loading at a warehouse to
unloading at the delivery point, because said system can operate only when the
engine is running. So, in the course of the product loading and unloading, as
well as in the course of the vehicle making stops, LNG supply to the engine is
ceased or substantially reduced, that automatically causes a significant
decrease or even termination of heat-insulated cargo compartment refrigeration.
Therefore, the actual task is to provide a vehicle
equipped with a refrigeration system for heat-insulated cargo compartments,
based on the heat content of the natural gas, used as a fuel, under conditions
when its aggregate state is changed before it is supplied into a vehicle
engine, as well as to provide enough refrigeration capacity for all the
transportation stages, from loading to unloading, wherein the refrigeration
system developed would allow for maintaining required temperature of the
compartment when the engine is off.
The closest prior art solution to the one suggested
is a refrigerated vehicle, running on the liquefied natural gas, described in
the patent China application No. 201907386 (published 07/27/2011). Said vehicle
for transporting thermally unstable products contains an internal combustion
engine with a power system and a heat-insulated tank for LNG (located under the
vehicle), an intake line, a dual-flow heat exchanger first circuit intended for
feeding the line, at least one heat-insulated cargo compartment, a heat carrier
circuit including the heat carrier flow control system, which are subsequently
arranged streamwise the liquefied natural gas (LNG) flow, and a cooling device
for cooling the internal space of the heat-insulated cargo compartment,
providing heat exchange between the heat carrier and the gas medium within the
internal space of the heat-insulated cargo compartment, a dual-flow heat
exchanger second circuit and a pump, which are subsequently arranged streamwise
the heat carrier flow. Whereby, the dual-flow heat exchanger is placed within
the heat-insulated cargo compartment.
Among the drawbacks of the above prior art one should
admit rather high probability of the heat carrier freezing within its
circulation circuit, as an excess cold accumulated by the heat carrier may
occur, that in its turn may lead to the heat carrier circulation stop and to a
significant reduction of the cooling efficiency within the internal space of
the heat-insulated cargo compartment. Another drawback of the solution as
described concerns the dual-flow heat exchanger being placed inside the
heat-insulated cargo compartment, that does not allow for providing a proper
safety level for the operating personnel, since, in the case of gas leakage,
the gas enters the cargo compartment closed space and, besides, the heat
exchanger occupies rather significant part of the heat-insulated cargo
compartment useful area. Furthermore, the above vehicle structure can’t be used
for trucks with trailers/semitrailers, as the dual-flow heat exchanger of said
structure is placed in the heat-insulated cargo compartment, i.e. within the
trailer/semitrailer, and the engine with LNG tank is located on the truck.
The drawbacks as mentioned reduce the temperature
control efficiency within the internal space of the heat-insulated cargo
compartment, as well as the refrigeration capacity of used equipment in
general. Since the heat carrier efficient cooling according to the
abovementioned solution is only possible under condition of a vehicle
engine-on, which is because in the course of product loading and unloading, as
well as in the course of the vehicle making stops LNG supply to the engine is
terminated or is substantially reduced, correspondingly when the heat carrier
circulation is restarted for maintaining the required temperature within the
heat-insulated cargo compartment the accumulated cold of the heat carrier is
quite rapidly utilized in the course of the heat exchange between the heat
carrier and the gas medium within the internal space of the heat-insulated
cargo compartment, whereby no further heat carrier cooling takes place.
Consequently, the cooling efficiency for the internal space of the
heat-insulated cargo compartment is reduced, that does not allow for providing
undamaged condition of thermally unstable products.
The object of the invention is to provide a
vehicle, which due to its design and its arrangements for cooling the internal
space of the heat-insulated cargo compartment allows for maximal efficient
temperature control within the internal space of the heat-insulated cargo
compartment of the vehicle at all stages of the vehicle operation while
transporting the thermally unstable products, that would provide undamaged
condition of the products being transported, and would allow for increasing
overall refrigeration capacity of the cooling equipment applied, as well as for
reducing fuel and lubricants consumption.
Another object of the invention is to provide a
method for transportation of thermally unstable products, which due to the
optimal operation sequence to be performed would allow secure transportation of
thermally unstable products, enabling maximal efficient temperature control
within the internal space of the heat-insulated cargo compartment at all stages
of the vehicle operation while transporting the thermally unstable products,
that in its turn would guarantee undamaged condition of the products being
transported and increase of overall refrigeration capacity of the cooling
equipment applied, and reduction of fuel and lubricants consumption, as well as
reduction of the content of harmful substances in the exhaust gas, and also
would provide all necessary conditions for the thermally unstable products
preservation and all the necessary safety precautions.
In order to solve the problem, it is provided a
vehicle for transporting the thermally unstable products, comprising an
internal combustion engine with a power system; and a heat-insulated tank for
LNG, an intake pipeline, a dual-flow heat exchanger first circuit, a feed
pipeline, at least one heat-insulated cargo compartment, a heat carrier circuit
including a heat carrier flow control system, which are subsequently arranged
streamwise the liquefied natural gas (LNG) flow, and a cooling device for
cooling the internal space of the heat-insulated cargo compartment, providing
heat exchange ability between the heat carrier and the gas medium within the
internal space of the heat-insulated cargo compartment, a dual-flow heat
exchanger second circuit and a pump, which are subsequently arranged streamwise
the heat carrier flow, whereby the dual-flow heat exchanger is placed within
the heat-insulated tank, filled with a heat-accumulating medium, wherein first
and second circuits of the dual-flow heat exchanger enabling the heat exchange
with said heat-accumulating medium, and as а heat-accumulating medium it is
chosen a medium, where the liquid-solid transition temperature exceeds such
transition temperature of the heat carrier.
The embodiment as described, due to the dual-flow
heat exchanger being arranged within a heat-insulated tank filled with a
heat-accumulating medium, as well as due to the difference in the heat carrier
and the heat-accumulating medium transition temperatures allows to eliminate
the heat carrier freezing within its circulation circuit, that in its turn
leads to maximal efficient temperature control within the internal space of the
heat-insulated cargo compartment at all stages of the vehicle operation, in
particular, in the course of the vehicle making stops and in the course of
thermally unstable products loading and unloading the heat carrier cooling is
performed through heat exchange between the heat carrier and said
heat-accumulating medium, whereby previously accumulated cold of the
heat-accumulating medium is utilized. When transporting thermally unstable
products the heat carrier is cooled through the heat exchange between the heat
carrier and said heat-accumulating medium, while utilizing the
heat-accumulating medium cold obtained due to the heat exchange between the
heat-accumulating medium and LNG. The arrangement for cooling the internal
space of the heat-insulated cargo compartment as described provides undamaged
condition of the products being transported and allows to increase overall
refrigeration capacity of the cooling equipment applied and to reduce fuel and
lubricant consumption.
According to a preferred embodiment of the vehicle
as claimed, the heat-insulated tank filled with heat-accumulating medium is
placed outside the heat-insulated cargo compartment in the immediate vicinity
of to the heat-insulated tank for LNG, thus resulting to shortening the
pipeline connecting said tanks, that in its turn makes it possible to reduce
operational loss of cold within the pipeline while transporting operation.
The device for cooling the internal space of the
heat-insulated cargo compartment can be a finned heat sink equipped with an air
fan increasing the heat exchange velocity due to the active air circulation
through the finned heat sink cooling surface.
The device for cooling the internal space of the
heat-insulated cargo compartment also may represent a set of eutectic
panels.
Besides, having the internal space of the
heat-insulated cargo compartment divided into different temperature zones, the
device for cooling the internal space of the heat-insulated cargo compartment
may represent a cooling system, comprising a finned heat sink equipped with an
air fan and a set of eutectic panels.
The use of LNG cold for cooling the
heat-accumulating medium with the vehicle engine on leads to the general
reduction of costs for cooling up to predetermined temperature and/or
maintaining the predetermined temperature of the thermally unstable products
while transporting thereof, and to the increase of the vehicle running distance
without forced stops necessary for cooling the heat-accumulating medium through
an external stationary source. Besides, a mention should be made that after
unloading the products being transported at the destination point on the
vehicle’s way back to the point where a new loading of thermally unstable
products is to be made, that is in the course of the empty vehicle trip, the
heat-accumulating medium also undergoes cooling, thus, enabling restart of
loading, once arrived at the loading point, with no previous cooling of the
internal gas medium within the heat-insulated cargo compartment, that in its
turn would reduce the contact time of the vehicle. Since the heat exchanger is
heat-insulated, the cold accumulated with the heat-accumulating medium can be
stored for a long time, for example, in the course of an overnight stay or a
long term stay before loading thermally unstable products that makes it
unnecessary to charge additionally the heat-accumulating medium with the cold
through a stationary source. All the mentioned above also concerns eutectic
panels cooling.
Preferably, when using the eutectic panels as a
cooling device or its component, the heat-insulated cargo compartment is
equipped with additional heat-insulating panels, able to be attached to the
ceiling and/or to the side walls of the heat-insulated cargo compartment,
wherein the eutectic panels are placed in the gap between the heat-insulated
cargo compartment ceiling/side walls and the heat-insulating panels. Such
embodiment of the invention as claimed allows providing, in case of eutectic
panels, a mediated (indirect) temperature control within the heat-insulated
cargo compartment through absorbing a part of the cold, released by the
eutectic panels into the heat-insulated cargo compartment environment, by the
suspended ceiling or side walls panels. Also, such embodiment of the invention
as claimed allows providing and to maintain different temperatures in different
zones within a heat-insulated cargo compartment. Said suspended ceiling panels
may be at least partially made of the heat-insulating material, and they also
may be detachable or slidable.
The heat-insulated cargo compartment may also
include an additional fan unit, enabling to increase or to reduce the heat
transfer from the cooling device within the heat-insulated cargo compartment
internal space.
The vehicle may be provided with a heat carrier
flow control system, which may include a pump, an electro-driven valve,
shut-off valves and quick release connections applied for connecting to an
external stationary cold source for cooling the heat-accumulating medium at the
stage of stopping and loading/unloading. Also, the flow control system may be
provided with temperature sensors mounted directly into the heat carrier flow
path, wherein the readings of said sensors are used for preventing the heat
carrier from freezing.
The LNG flow control system performed by means of
a dual-flow heat exchanger, mounted into the heat-insulated tank and filled
with a heat-accumulating medium, comprises an electro-driven valve.
According to the preferred embodiment, the finned
heat sink is equipped with an air fan, thus increasing the heat exchange
velocity due to the active air ventilation through the finned heat sink cooling
surface.
It is reasonable to use ethylene glycol aqueous
solution as a heat-carrier. It is also efficient to apply ethylene glycol
aqueous solution as a heat-accumulating medium, wherein the freezing
temperature of the solution can be varied through changing ethylene glycol
percentage.
Preferably, the vehicle is a vehicle chosen from
the group including an air transport, a waterborne craft and a rail
transport.
The road vehicle is a vehicle chosen from the
group including a truck, a tractor-trailer/semitrailer.
The tractor-trailer/semitrailer comprises a
heat-insulated tank, filled with a heat-accumulating medium, and a
heat-insulated tank for LNG which is mounted onto the tractor and а cooling
device placed within the trailer/semitrailer, wherein the heat-carrier
circulation circuit is equipped with quick release connections which allows to
disassemble the tractor and trailer/semitrailer common cooling system through
the heat-carrier circulation circuit, if required.
According to one of preferred embodiments, the
vehicle is equipped with an additional heat exchanger mounted into the
heat-insulated cargo compartment connected to an additional heat-insulated tank
with coolant by means of a pipeline equipped with a controlled valve. Such an
embodiment as claimed allows providing extra cooling of the heat-insulated
cargo compartment internal space.
Preferably, the vehicle is equipped with at least
one gas analyzer.
According to another preferred embodiment of the
vehicle as claimed, the heat-insulated cargo compartment comprises at least one
temperature sensor providing the temperature control inside the compartment.
The dual-flow heat exchanger may be equipped with a temperature sensor
either.
Another object of the invention is to provide a
method for transportation of thermally unstable products, the method comprising
preparing a tank for the liquefied natural gas (LNG) onboard for powering an
internal combustion engine of a vehicle and cooling the heat-insulated cargo
compartment internal space, loading the thermally unstable products into the
cargo compartment of the vehicle, running the loaded vehicle from a place of
loading to a point(-s) of destination and unloading the thermally unstable
products out of the cargo compartment of the vehicle at the point(-s) of
destination, wherein at the stages of loading/unloading, making stops and
running the loaded vehicle from the place of loading to the point(-s) of
destination the cargo compartment is thermally regulated, wherefore the use is
made of a dual-flow heat exchanger and the device for cooling the
heat-insulated cargo compartment internal space, said heat exchanger and
cooling device are connected through a heat-carrier circulation circuit. The
dual-flow heat exchanger is mounted into a heat-insulated tank filled with a
heat-accumulating medium being cooled at the stage of running through utilizing
the cold of LNG before it is supplied to the engine, wherein the cargo
compartment is thermally regulated by means of the device cooling the
heat-insulated cargo compartment internal space due to the heat exchange
between the dual-flow first and second circuits and said heat-accumulating
medium.
If necessary, when the cold accumulated at the
stage of running is insufficient, or if the vehicle is used after a long
stopping, the heat-accumulating medium is cooled by means of an external
stationary cold source at the stage of stopping and loading/unloading.
According to a preferred embodiment, the
heat-insulated tank and the heat-accumulating medium therein, the eutectic
panels and the amount of heat-accumulating medium within the latters, and a
tank with liquid nitrogen or liquid CO2 are chosen such that the amount of cold
obtained from an external stationary source and the amount of cold obtained
through utilizing the cold of LNG before it is supplied to the engine exceeds
the amount of cold needed to maintain the required temperature within the
heat-insulated cargo compartment internal space. This allows avoiding the
necessity of any extra equipment for cooling the heat-insulated cargo
compartment internal space.
Placing the dual-flow heat exchanger inside the
heat-insulated tank filled with a heat-accumulating medium allows for providing
the refrigeration capacity required to stand the maximal loads of the cooling
equipment mounted onto the vehicle. Furthermore, the use of the LNG cold for
cooling the heat-accumulating medium leads to a significant reduction of other
coolants to be used, such as liquid nitrogen, and also increase the vehicle
operation time between procedures for cooling the heat-accumulating medium to
be performed through an external stationary cold source during stopping.
Besides, it allows for reducing fuel and lubricants consumption, as well as for
reducing the content of harmful substances in the exhaust gas.
Due to the optimal sequence of the operations to
be performed, the embodiment of the technical solution as claimed allows for
providing reliable transportation of thermally unstable products, thus,
ensuring maximal efficient temperature control within the heat-insulated cargo
compartment internal space at all stages of the vehicle operation when
transporting the thermally unstable products, resulting in undamaged condition
of the products being transported and increasing overall refrigeration capacity
of the cooling equipment applied, as well as reducing fuel and lubricants
consumption, and also provides all the conditions for the thermally unstable
products preservation and all the necessary safety precautions.

Further, it is described an embodiment of the
invention as claimed wherein the cooling device for cooling the internal space
of the heat-insulated cargo compartment may represent finned heat sink,
equipped with an air fan.
Preliminary at specially provided points it is
performed filling the LNG tank 4 with liquidized natural gas (LNG) onboard the
vehicle 1 for powering the internal combustion engine 2 of the vehicle 1 and
ensuring the cooling device 7 operation for cooling the heat-insulated
compartment 5 internal space of the vehicle 1. Further, it is performed
preliminary cooling the heat-accumulating medium within the heat-insulated tank
8. If necessary, it is performed filling the additional heat-insulated tank
(not shown) intended for coolant and provided onboard the vehicle 1 for feeding
certain types of cooling systems used as additional equipment for temperature
control within the internal space of the heat-insulated cargo compartment 5.
Then the thermally unstable products are loaded into the cargo compartment 5 of
the vehicle 1 and transported from the place of loading to a point (-s) of
destination. At the stage of transporting the cargo compartment 5 is thermally
regulated, wherefore the use is made of the dual-flow heat exchanger containing
a first circuit and a second circuit and a finned heat sink providing heat
exchange between the heat carrier and the gas medium within the internal space
of the heat-insulated cargo compartment 5 which are connected through the heat
carrier circuit, wherein the temperature control inside the compartment is
provided by means of at least a temperature sensor (not shown). Whereby the
dual-flow heat exchanger is placed into a heat-insulated tank 8 filled with a
heat-accumulating medium, being cooled by means of an external stationary cold
source at the stage of stopping and loading/unloading.
The internal space of the heat-insulated cargo
compartment 5 undergoes cooling at the stage of transporting, the cooling being
performed as follows. Upon the vehicle ignition starting a valve for the engine
2 operation is open. LNG is supplied from the heat-insulated tank 4 through the
intake pipeline to the heat exchanger first circuit through the open
electro-driven valve. The heat exchange occurs between LNG and the
heat-accumulating medium contained in the tank 8. The first circuit output is
connected to the power system 3 of the engine 2 through a feed pipeline for
supplying a gaseous fuel to the engine 2. If required, the fuel supply to the
heat exchanger first circuit may be reduced or stopped.
At the same time a heat exchange is provided between
the heat-accumulating medium and the heat carrier circulating within the heat
carrier circulation circuit comprising a heat carrier flow control system
comprising shut-off valves and quick release connections 6; and a finned heat
sink equipped with an air fan, a dual-flow heat exchanger second circuit and a
pump, which are subsequently arranged streamwise the heat carrier flow. By
means of the pump the heat carrier circulates within said circuit. By means of
the finned heat sink it is provided a heat exchange between the heat carrier
and the gaseous medium within the internal space of the heat-insulated cargo
compartment 5. Then the heat carrier having changed temperature is returned
from the finned heat sink to the heat exchanger second circuit for cooling. At
the stage of stopping, loading/unloading when the internal combustion engine 2
is off, the circulating heat-carrier undergoes cooling due to the heat exchange
with the heat-accumulating medium.
Thus, the invention as claimed represents a vehicle
which, due to its design and its arrangements for cooling the internal space of
the heat-insulated cargo compartment, allows for maximal efficient temperature
control within the internal space of the heat-insulated cargo compartment at
all stages of the vehicle operation while transporting the thermally unstable
products, resulting in undamaged condition of the products being transported,
and in increasing overall refrigeration capacity of the cooling equipment
applied, as well as in reducing fuel and lubricants consumption.

sequence of operations to be performed would allow for secure transportation of
thermally unstable products, enabling maximal efficient temperature control
within the internal space of the heat-insulated cargo compartment at all the
stages of the vehicle operation while transporting the thermally unstable
products, that in its turn would guarantee undamaged condition of the products
being transported and would allow for increasing overall refrigeration capacity
of the cooling equipment applied, and for reducing fuel and lubricants
consumption, as well as for reducing the content of harmful substances in the
exhaust gas, and also provides all the conditions for the thermally unstable
products preservation and all the necessary safety precautions.
