FIELD OF THE INVENTION:
The present invention relates generally to the field of thermoelectric devices and
more particularly to the thermoelectric cooling system with improved
performance and/or efficiency. The present invention is designed for cooling
system such as evaporative air/desert cooler, air conditioner etc. by using
dehumidifying/thermoelectric cooling devices. More specifically, the invention
relates to a liquid-cooling system.
PRIOR ART:

Vaayu India hybrid chiller, which comes with a technology of blending the
traditional coolers with compressor. The entire refrigeration cycle inside a cooler-
body.

BACKGROUND OF INVENTION:
Thermoelectric cooling system is analogous to conventional air conditioning
cooling systems. For example, a conventional cooling system, includes an
evaporator, a compressor, and a condenser. In the evaporator or cold section,
pressurized refrigerant is allowed to expand, boil, and evaporate. During the
change of state from a liquid to a gas, energy in the form of heat is absorbed. In
the next step, the compressor re-compresses the gas into a liquid. Further, the
condenser expels the heat absorbed at the evaporate and the extra heat added by
the compressor to the ambient environment.
OBJECTIVE OF THE INVENTION:
• The present invention provide a solution by providing a hybrid cooling machine, with the placement of this machine; cooling like an air conditioner can be generated.
• An object of this invention is to provide cooling just like air conditioner with low consumption of electricity.
• Another object of this invention is to provide a low cost cooling machine, within the purchasing power of the general public.
STATEMENT OF INVENTION:
• The primary advantages of a thermoelectric module aS compared to a vapor-compression refrigerator are its lack of moving parts or circulating liquid, very long life, invulnerability to leaks.
• By placement of this system in air cooler as well as ac, we found most effective cooling. Its cooling is like an air conditioner.
• This is thermoelectric effect based cooling system for both air conditioner as well
i as air cooler. There is no refrigeration cycle, so no extra heat added by the
compressor to the ambient environment.

SUMMARY OF THE INVENTION:
■For Evaporative Air/Desert Cooler:
• The present invention precooling the water and the air used in an evaporative cooler by a thermoelectric cooling element, particularly so that the effective operational range of the evaporative cooler may thereby be extended to higher ambient temperatures.
• More particularly, the thermoelectric cooling element for cooling the water prior to its evaporation by the evaporative cooler.
• The hybrid cooling system 1 may be generally described as a thermoelectric cooling system having an electric circuit comprising a dc power source for providing direct current throughout the electric circuit, a thermoelectric module having-at least one heat sink and at least one heat source capable of being cooled to a predetermined temperature range, water block and a temperature control unit. The dc power source, the temperature control unit, and,the thermoelectric module are connected to each other in parallel. The temperature control unit comprises a
■ thermostat control switch mechanism. The thermostat .control switch mechanism
has a sensor coupled to or thermally associated with the cold source of the
- ■,. * . thermoelectric module so that the temperature of the cold source can be
* monitored. The thermostat control switch mechanism is normally open in the
predetermined temperature range detected by the sensor.
• Thermoelectric module operates according to the Peltier effect. The effect creates a temperature difference by transferring heat between two electrical junctions. A voltage is applied across joined conductors to create an electric current. When the current flows through the junctions of the two conductors, one side gets chilled while the other gets hotter, heat sink and cooling fan is attached, which prevents it from heating up.
• A water block is .the water-cooling device equivalent of a heatsink. There is one inlet and one outlet valve in the water block. The water block will receive the water from inlet and send it through the outlet valve.
• The cold side thermoelectric module is attached to a water block is placed inside the evaporative cooler for cooling of the space and on the other hand, hot side of thermoelectric module attached with a heat sink and cooling fan, which placed outside of evaporative cooler for heat rejection.
For Window Air - Conditioner: %
• Inside an air conditioning system is a chemical refrigerant which is a compound
that easily changes states from liquid to vapor and.back again. During the change
of state from a liquid to a gas, energy in the form of heat is absorbed. In the next
step, the compressor re-compresses the gas into*a liquid. Further, the condenser
expels the heat absorbed at the evaporator and the extra heat added by the
compressor to the ambient environment.

DETAILED DESCRIPTION OF THE INVENTION:
For Evaporative Air/Desert Cooler:*
• The Figure 1, Show the hybrid cooling system 1. The hybrid cooling system has two thermoelectric modules 1, 2. The heat sink 3 is attached to the hot side of the thermoelectric module. A cooling fan 4 is also attached to the heat sink, which prevents it from heating up. A water'block 5 is attached to the cold side of the thermoelectric module. There are. two valve, inlet 5A and outlet valve 5B in the water block. DC power supply 6.is connected to the thermoelectric module 1, 2, cooling fan 4 and temperature control unit 7. The temperature control unit 7 is connected to the outlet valve 5B of the water block to maintain the water temperature.
• The figure 2 shows the placement of hybrid cooling system 1 in the Air cooler. The inlet valve 5 A of water block 5 is connected to the air cooler water pump and
, the outlet valve 5B of water block 5 is connected to air cooler net/pads.
• On starting the Air cooler, the thermoelectric module is also started. The air
cooler water pump, -pumps the water from water tank to the thermoelectric
module water block 5. The water block will receive the water from inlet valve 5 A
and send the chilled water through the outlet valve 5B. The water starts chilling
on .flowing through it. The water got chilled up to 3 - 5 degrees Celsius. This
chilled water is then be used for cooling.
I. In this method, chilled water is used by pouring directly over the net/pads of the air cooler. With this method, cooling machine brings down the temperature in the range of 17 to 30 degree Celsius. *
For Window Air - Conditioner:
• The figure 3 shows the complete Hybrid cooling system 2 for placement in air conditioner. The figure 4 shows the placement of hybrid cooling system 2 in the window air conditioner.
• To achieve the effective cooling four thermoelectric modules 1,2,3,4 are used. As mentioned above, the antifreeze is also added to water, which will not let the water to freeze. The ratio of water and antifreeze is 50:50. The water block 5 is attached to the cold side of the thermoelectric modules. The water is. lifted with the. help of pump from tank to the inlet 5A of water block 5, and receives the water from outlet valve 5B of water block 5 shown in figure 3. The outlet valve 5B of water block 5 is connected to the evaporator coil, and the other side of the evaporator cooling coil is connected to the water tank as shown in figure 4.
