BACKGROUND
[0002] This invention relates to an air-conditioning system for
cabins of motor vehicles and watercrafts and aircrafts etc. More
particularly it relates to an air-conditioning system where a
thermo electric chip is used and/or direct current battery such
that the air-conditioning is operative even without the idling the
engine of the motor vehicle or watercraft.
THE PROBLEM
[0003] Truck drivers who spend major portion of their lives on road
need rest & sleep at times. Usually they park in a rest house
parking lot or on truck stops to get some sleep. The problem is to
beat the heat in the cabin, they have to turn on the truck air
conditioner. This means running the truck engine at idle condition.
Even though this solves the problem but it creates many others.
[0004] The noise of idling engine & the horrendous pollution it
creates are the major problems. The gasoline consumption when the
trucker is sleeping for 4 to 8 puts a dent on their economy
operation. Similar problem exists for Boat Cabins & small
cabins of tents when camping.
[0005] It is thus apparent that the need exists for an apparatus
for cooling the cabins which provides adequate cooling of the air
in the sleeping compartment as well as conserving the fuel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0036] The compact, convenient and solid state personal direct
current mini air-conditioning system 99 of this invention as shown
in the drawings wherein like numerals represent like parts
throughout the several views, there is generally disclosed in FIG.
1 a typical layout of the preferred embodiment of the invention in
the cabin 80 of a motor vehicle 400 complete with sleeping bunk 40,
direct current battery 30, thermoelectric chip 20 bank on a heat
sink and solar panel 50.
[0037] The essence of the preferred embodiment comprises a thermo
electric module which in turn comprises a solid state thermo
electric chip. The system also includes a heat sink, a cold sink
and a direct current power source as well as a switch and
associated hardware.
[0038] FIG. 2 shows a more detailed layout of the preferred
embodiment utilizing Thermoelectric technology complete with
ambient air intake, hot air vent, cool air to the cabin generated
by the thermoelectric chip bank on a heat sink.
[0039] Having reference to the drawings, attention is directed
first to FIG. 1, which illustrates the air conditioning system 99
of the preferred embodiment of this invention as it is installed in
its operative position, with air conditioning unit designated
generally by the numeral 10. As can be seen, the invention is
installed in operative relationship in a truck/boat cabin 80 and
has one of its primary component, a cooling unit 1 positioned
interiorly near the sleeping area 40 of the cabin 80.
[0040] As can be seen in FIG. 1, the preferred embodiment cooling
system 99 in addition to the cooling unit 10, comprises two other
primary components viz the electronic thermostatic controller 20
and the deep cycle marine battery 30. Cooling unit is disclosed in
more detail in FIGS. 2-4. Figures one and two illustrate the
preferred embodiment utilizing the thermoelectric chips on heat
sink. Figure three illustrates first alternate embodiment utilizing
high efficiency direct current compressor and also energized by a
marine direct current battery. .linevert split.Figure three
illustrates a second alternate embodiment employing cold storage
phase change material As can be seen in FIG. 2, the cooling unit 10
of this invention discloses one of the many ways that accomplishes
the desired cooling purpose.
[0041] FIG. 2 discloses the preferred embodiment, solid state
electronic cooling. Thermoelectric cooling unit 10 having a means
of ambient air intake conduit 100. This conduit 100 extends from
outside of the cabin 80 into the interior. This inlet ambient air
is incorporated in the cooling unit 10 itself. Cooling unit 10
comprises of a hot air chamber 110 and a cool air chamber 120,
having insulated walls 140, with the most important insulated wall
being a center dividing wall 130. A power conduit 150 extends from
electric thermostat controller 20 of FIG. 1, preferably through the
air intake conduit 100 into the hot air chamber 110 and then to the
insulated walls 140 where the power conduit 130 is secured to
thermoelectric chip 150.
[0042] The thermoelectric chip 155 is typical of those already in
existence, such as the semi conductor material Bismuth Telluride is
doped to make `p` and `3n` materials. The small pieces (legs) of
these `p` and `n` materials are connected electrically in series
and thermally in parallel. This arrangement is sandwiched between
two ceramic plates. Two wires are soldered, one to the starting p
material leg which is labeled as positive and the other wire to the
last n material leg which is labeled as negative. The
thermoelectric chip is positioned between two adhesive layers 160,
one of which is in contact with hot side heat sink 180, having back
wall 190 and a plurality of horizontally disposed fins 175 on heat
sink 180 to assist in the disposition of heat as the hot air passes
through & over the fins 175. The other adhesive layer 160 is in
contact with a heat conducting block 200. Although in the
embodiment of this invention 99, the cold temperature conducting
block 200 serves to provide a cooling portion 170 preferably in the
form of a plurality of horizontally disposed fins 175 which cools
the air in the cool air chamber 120 as the air passes over the and
through the fins 175. The cool temperature conducting block 200 is
preferably fabricated from aluminum. Maximum heat absorption and
cooling occurs when the air entering chamber 10, due to the
location of the air access, passes directly over the fins 175.
[0043] Two fans 210, 220 assist in circulating the hot air into the
hot air chamber and thence from it, helping to circulate the cool
air from the cool air chamber into the sleeping cabin 80 in FIG. 1.
The first of these fans is an exhaust fan 210 which helps to draw
air through an air intake port 100 past the heat sink 180 and its
fins 175 and then expel the heated air through exhaust conduit 230
having a closure means in the form of either a filter or one-way
valve. Meanwhile, the cooling fan 220 also draws air from conduit
150 across the cooling portion block 200 and forces through the
cool air conduit 240 into the sleeping cabinet 80. Power for both
of these fans 210, 220 is also preferably provided by the power
conduit 150 which takes its energy from the auxiliary battery 30 in
FIG. 1. or 330 in FIG. 3
ALTERNATE EMBODIMENTS
[0044] FIG. 3 shows a block diagram of an alternate embodiment
utilizing a high efficiency direct current compressor 320 energized
by a marine battery 330 and optionally charged by the alternator of
the motor vehicle engine 420 and or solar panel 350.
[0045] This alternate method of achieving the purpose of this
invention is to use the technology of a small high efficiency D C
compressor 320 driven air conditioner 199 of a minimum 2,400 BTU
capacity as shown in FIG. 3, to cool the sleeping cabin 80.
[0046] This DC air conditioner 199 may be placed above the battery
30 in FIG. 1 corresponding to 330 in FIG. 3. The battery 330
energizes either the Thermoelectric Chips 155 or the compressor 320
of DC air conditioner 199. The battery 330 also energizes the fans
210, 220.
[0047] In this alternate embodiment KABLNKOOL is a battery operated
refrigeration system 199, that is, it uses direct current to run
the compressor 320.
[0048] However, one can use alternate current (AC) equipment such
as battery charger to charge the battery first and then connect the
battery to the DC air conditioner.
[0049] Another source of power that can use is DC generator, but it
must have a stable voltage. One can operate 12 V KABINKOOL directly
from a converter or rectifier, provided that the rectifier or
converter has a stable 12 V output and capable of producing high
start-up or surge current. It may be cheaper to use battery and
solar modules to recharge the battery.
[0050] In this alternate embodiment the inventor utilized the
following specifications for the D C Air Conditioner but variations
of it may be equally satisfactory.
[0051] a) Compressor: 12 V or 24 V DC compressor
[0052] b) Cooling capacity: 600 watts (2040 Btu)
[0053] c) Cooling space: 7 ft .times.7 ft .times.7 ft (343
ft.sup.3)
[0054] d) Electricity: DC 12 V @ 15 A & DC 24 V @ 7.5 A
[0055] e) Refrigerant: HFC-134a
[0056] f) Ambient air temperature: 24 to 33 degrees C.
[0057] g) Room temperature: 23 to 25
[0058] h) Thermostat: UT72, temperature ranges .about.30 to +30
degrees C.
[0059] i) Dimensions: (L.times.B.times.H): 32.0 in .times.29 in
.times.18 in
[0060] j) Weight (approximately): 32 kg
[0061] The latest "AGM" (Absorbed Glass Mat) battery has a full
100% recharge rate. Most battery-operated systems use solar module
as a recharging device. The sun is free and more practical in the
long run. Furthermore it is very convenient in areas without
electricity. The requirement of the solar module power depends on
the current consumption.
[0062] KABINKOOL can use normal motor vehicle battery to operate.
In fact any 12 Volt battery source which is easily available. In
general it is all the time lead acid type. However alkaline battery
is getting popular and at the moment they are expensive Solar deep
cycle battery is preferable for storage of solar converted
electricity. The normal truck battery is good and will last longer
if each recharging can top-up to its maximum capacity. However in
solar recharging system, battery is almost drained flat and
recharging by solar modules cannot guarantee full recharge every
time. Most of the time recharging is very slow. Hence most car
battery can last about 2 years. Solar deep cycle battery does not
have this problem and will last about 5 years in normal
service.
[0063] For any 12 V/24 V system, the problem is recharging the
battery after it is drained flat. In a vehicle, the practice is to
divert a separate wire from the vehicle's dynamo to charge the
battery meant specifically for running the air-con. In this way,
one can have days of comfortable 12 V air-con running in the camp.
For a 12 V battery with a power capacity 240 AH, the 12 V KABINKOOL
will last for about 10 hours without recharging on continuous
operation, as KABIKOOL consumes about 18.75 AH. When KABINKOOL is
running with thermostatic control of 70:30 on-off 25 cycle, 240 AH
battery can last for about 16 hours.
[0064] FIG. 4 shows yet another alternate embodiment utilizing cold
storage phase change material 410 energized by the direct current
battery 430 of the motor vehicle cabin 80 and optionally charged by
the alternator 425 of the motor vehicle engine 420 and or solar
panel 50, 350. This embodiment utilizes "Phase Change material" 410
which holds the needed cold temperature as shown in FIG. 4. When
the truck or boat is parked then this cold storage material absorbs
the heat in the cabin for 8 hours thus keeping the cabin cool. The
phase change material is "Charged" by the regular truck air
conditioner while driving.
OPERATION
[0065] Comfort of a person depends upon temperature, humidity, air
quality and circulation. Body adjustments are accomplished by the
circulatory and respiratory systems. When sweat evaporates, it
takes away heat in the form of heat of vaporization from the body
and cools it. Human body gives off and absorb heat by the three
methods of heat transfer: conduction, convection and radiation.
Evaporation, in the form of perspiration, could be considered the
fourth way. The surroundings must be cooler than the body for the
body to be comfortable. Typically, when the body is at rest, such
as sitting, in a surrounding of 25 degrees Celsius (77 Degrees
Fahrenheit) and 50% humidity with a slight air movement, the body
is being comfortable during a hot day.
[0066] KABINKOOL is suitable for any insulated room around 350
cu.ft. (10 cu in). For a room of this size our air-con can maintain
the temperature for around 23 to 25 degrees Celsius and humidity of
about 50%. The most important characteristic with this is that it
will reduce the humidity inside the room, hence you will feel
comfortable and cool even though the temperature is around 27
degrees C. The dehumidifying capacity of KABINKOOL is about 1
gallon of water per day. The smaller the room, the lower the
temperature will be.
[0067] It is advisable to keep the KABINKOOL away from other heat
sources, e.g. engine room, which will increase the current
consumption of your KABINKOOL. Always operate the unit with high
fan speed to get maximum cooling capacity. The portable 12 V/24 V
KABINKOOL very useful for camping tent. In fact it can be used for
any small rooms. One of the practical functions for our KABINKOOL
is in interstate truck's sleeper cabin.
[0068] KABINKOOL'S cooling capacity is only about 2040 Btu (600
watts). For rough estimation purposes, a person needs about 5 Btu
per cu ft of well insulated space. For 7.times.7.times.7 feet
volume, this amounts to 1,715 BTU. In addition to this, while
asleep a person generates about 275 Btu (80 watts) of heat load.
Therefore, a 2040 BTU capacity air conditioner will do the job
adequately.
[0069] The use and operation of this device by a consumer is simple
and even intuitive. Nonetheless the inventor recommends the
following steps:
[0070] a) The cabin is first insulated with the Insulation of high
"R" value. The Aerogel, Vacuum Panels & similar insulation may
be used.
[0071] b) Second, a solar panel is mounted on the roof of the cabin
which generates sufficient electricity to at least trickle charge a
marine battery.
[0072] c) A marine deep cycle discharge battery of at least 240
AmpHr capacity is placed in the cabin. The solar panel trickle
charges this battery when the cabin cooler is not in use. Also, a
wire may be connected from the truck alternator to charge the
battery when the engine is turned on.
[0073] d) A plastic box containing solid state cooling
Thermoelectric Chips of total capacity of 2,400 BTU (minimum) is
placed above the battery. The box also contains the blower to blow
the cold air to the cabin. A fan which blows the air on the hot
side of the heat sink is vented out side the cabin. A small hole
may be drilled for this purpose.
[0074] The solid state electronic Thermoelectric "Chip" cools a
given volume of space without bulky compressors, CFC gases, coils
etc. This space age technology uses the power from direct current
source and keeps the cabin of a motor vehicle, watercraft, aircraft
or the like confined space at the right temperature and humidity.
By varying the current the inside temperature of the humidor can be
accurately varied. An HQ circuit senses the temp and with the help
of a thermostat it keeps the temperature at a pre-set level The
batteries are rechargeable. The operator after preparing the cabin
as per instructions merely connects the mini-air-conditioning
system to the direct current battery of the motor vehicle.
Optionally Alternating current charger of the motor vehicle and a
solar panel may be connected for more efficient use and longer life
of the battery.
[0075] The inventor has given a non-imiting description of the
concept. The simplicity and the elegance of the design of this
invention makes it difficult to design around it. Nonetheless many
changes may be made to this design without deviating from the
spirit of this invention. Examples of such contemplated variations
include the following:
[0076] 1. The shape and size materials of the various members and
components may be modified.
[0077] 2. A different thermoelectric module may be used.
[0078] 3. The color, aesthetics and materials may be enhanced or
varied.
[0079] 4. Additional complimentary and complementary functions and
features may be added.
[0080] 5. A more economical version of the device may be
adapted.
[0081] 6. An informational or advertising message may be
incorporated for promotional give aways.
[0082] 7. A different type of insulation may be provided.
[0083] 8. The volume and the cooling capacity may be varied by use
of a thermoelectric module of appropriate specifications.
[0084] Other changes such as aesthetics and substitution of newer
materials as they become available, which substantially perform the
same function in substantially the same manner with substantially
the same result without deviating from the spirit of the invention
may be made.
