Definitions
- Embodiments of the present invention relate to systems and methods for generating heat, and more particularly, to hybrid hot water heater systems and related methods for absorbing heat in ambient air and transferring it to water.
- water heating is a thermodynamic process for increasing water's temperature above its initial temperature by using an energy source.
- energy sources for heating water, such as, for example, fossil fuels including natural gas, liquefied petroleum gas (Hereinafter '"LPG"), oils, solid fuels and the like.
- water heaters can be classified according to various generations like a first generation of water heaters refers to water heaters utilizing a gas as an energy source.
- the gas can either be the natural gas or the LPG.
- a gas- operated water heater includes a housing and an upright open-ended mixing tube defining a combustion chamber in the housing.
- the combustion chamber has gas burners, and the combustion product gases are drawn into the mixing tube by lowering of pressure therein caused by directing a spray of finely-divided water particles down the tube. Heat exchange between the combustion gases and the water takes place in the tube, and both water and gases flow out at the lower end of the tube.
- frequent use of gas for heating water may cause environment pollution by release of harmful residual gases.
- production of gas heaters is expensive and subsequently, the gas water heaters are complex in structure.
- an electric water heater includes a housing made of a polymer material.
- the housing defines an internal passageway adapted for fluid flow through the housing.
- the housing has a first opening in fluid communication with the passageway, and a pair of access openings.
- the housing also includes a second opening in fluid communication with the tubing system.
- the heater also includes a heater tube defining a first end connected to the first opening in the housing.
- An elongated electrical heat pipe is partly disposed within the outer tube, and has opposite ends extending out of the first end of the heater tube and through the pair of access openings.
- the electrical heater includes compressions fittings connecting the heater tube and the elongated heat pipe by seals to the housing.
- a third generation of water heaters refers to water heaters utilizing solar energy as an energy source.
- Solar energy is the energy from sun typically in a form of heat and light.
- a solar water heater includes a water tank, a solar heating compartment for heating water, and an air pump.
- the water ' tank and the solar heating compartment are generally cylindrical, and the bottom surface of the heating compartment overlaps the top surface of the water tank.
- the solar heating compartment has an upper surface and a side surface which are usually constructed from transparent materials.
- the heating compartment contains water tubing in communication with water in the water tank and one stainless steel parabolic reflector positioned for reflecting incident sunlight upon the water tubing for absorption. The water tubing terminates in one of the hot water outlets.
- the air pump is in communication with the water tubing within the solar heating compartment. Operation of the air pump causes a stream of water to continuously flow from the water tank to the hot water outlets by the siphoning effect.
- solar water heaters are highly restricted by the presence or absence of the sun. Furthermore, solar water heaters cannot operate during nights and their use is further limited by poor weather conditions like rainfall, snowfall, storms and other similar poor visibility natural conditions during daylight. Moreover, manufacturing and installation of solar water heaters is expensive and complex, thereby limiting its use in rural areas.
- a fourth generation of water heaters includes water heaters using a heat pump cycle as a source of energy for heating water.
- a control unit has a heat-radiation determining mechanism for determining a heat radiation from refrigerant to outside air in an air heat exchanger based on a water temperature flowing into a water heat exchanger, and the control unit selectively performs a general cycle operation and a bypass operation in accordance with a determination result of the heat- radiation determining mechanism. That is, when the water temperature flowing into the water heat exchanger is lower than 60°C, the general cycle operation is performed. On the other hand, when the water temperature is equal to or higher than 60°C, the bypass operation is performed.
- the heat pump water heaters require a large amount of space for their installation and operation. Moreover, these water heaters require continuous air circulation for their operation thereby limiting their usage. Furthermore, the heat pump water heaters take heat from the surrounding air and therefore, as a result, they cool and dehumidify a surrounding space. Further drawbacks of the fourth generation water heater are bulky system again leading to a large requirement of space for its installation, noisy operation leading to noise pollution, lengthened heating time resulting in consumption of a large amount of energy, a complicated maintenance procedure and the like

Description
SYSTEMS AND METHODS FOR HEATING WATER BY ABSORBING HEAT IN AMBIENT AIR
Technical Field:
Embodiments of the present invention relate to systems and methods for generating heat, and more particularly, to hybrid hot water heater systems and related methods for absorbing heat in ambient air and transferring it to water.
Background Art:
Conventionally, water heating is a thermodynamic process for increasing water's temperature above its initial temperature by using an energy source. There are several devices available worldwide to provide a continuous supply of hot water, such as, for example, water heaters, boilers, heat exchangers, calorifiers, geysers and the like for various commercial and domestic purposes. These devices use various types of energy sources for heating water, such as, for example, fossil fuels including natural gas, liquefied petroleum gas (Hereinafter '"LPG"), oils, solid fuels and the like.
Generally, water heaters can be classified according to various generations like a first generation of water heaters refers to water heaters utilizing a gas as an energy source. As discussed above, the gas can either be the natural gas or the LPG. Typically, a gas- operated water heater includes a housing and an upright open-ended mixing tube defining a combustion chamber in the housing. The combustion chamber has gas burners, and the combustion product gases are drawn into the mixing tube by lowering of pressure therein caused by directing a spray of finely-divided water particles down the tube. Heat exchange between the combustion gases and the water takes place in the tube, and both water and gases flow out at the lower end of the tube. However, frequent use of gas for
heating water may cause environment pollution by release of harmful residual gases. Further, production of gas heaters is expensive and subsequently, the gas water heaters are complex in structure.
Similarly, a second generation of water heaters refers to water heaters utilizing electricity as an energy source for heating water. Generally, an electric water heater includes a housing made of a polymer material. The housing defines an internal passageway adapted for fluid flow through the housing. The housing has a first opening in fluid communication with the passageway, and a pair of access openings. The housing also includes a second opening in fluid communication with the tubing system. The heater also includes a heater tube defining a first end connected to the first opening in the housing. An elongated electrical heat pipe is partly disposed within the outer tube, and has opposite ends extending out of the first end of the heater tube and through the pair of access openings. The electrical heater includes compressions fittings connecting the heater tube and the elongated heat pipe by seals to the housing. The electric water heaters suffer from a big disadvantage as these consume a lot of energy thereby increasing an operational cost leading to their restricted use in cost-effective environments.
A third generation of water heaters refers to water heaters utilizing solar energy as an energy source. Solar energy is the energy from sun typically in a form of heat and light.
Generally, a solar water heater includes a water tank, a solar heating compartment for heating water, and an air pump. The water' tank and the solar heating compartment are generally cylindrical, and the bottom surface of the heating compartment overlaps the top surface of the water tank. The solar heating compartment has an upper surface and a side surface which are usually constructed from transparent materials. The heating compartment contains water tubing in communication with water in the water tank and one stainless steel parabolic reflector positioned for reflecting incident sunlight upon the water tubing for absorption. The water tubing terminates in one of the hot water outlets.
The air pump is in communication with the water tubing within the solar heating compartment. Operation of the air pump causes a stream of water to continuously flow
from the water tank to the hot water outlets by the siphoning effect. However, the use of solar water heaters is highly restricted by the presence or absence of the sun. Furthermore, solar water heaters cannot operate during nights and their use is further limited by poor weather conditions like rainfall, snowfall, storms and other similar poor visibility natural conditions during daylight. Moreover, manufacturing and installation of solar water heaters is expensive and complex, thereby limiting its use in rural areas.
A fourth generation of water heaters includes water heaters using a heat pump cycle as a source of energy for heating water. Typically, in a heat-pump water heater, a control unit has a heat-radiation determining mechanism for determining a heat radiation from refrigerant to outside air in an air heat exchanger based on a water temperature flowing into a water heat exchanger, and the control unit selectively performs a general cycle operation and a bypass operation in accordance with a determination result of the heat- radiation determining mechanism. That is, when the water temperature flowing into the water heat exchanger is lower than 60°C, the general cycle operation is performed. On the other hand, when the water temperature is equal to or higher than 60°C, the bypass operation is performed. However, the heat pump water heaters require a large amount of space for their installation and operation. Moreover, these water heaters require continuous air circulation for their operation thereby limiting their usage. Furthermore, the heat pump water heaters take heat from the surrounding air and therefore, as a result, they cool and dehumidify a surrounding space. Further drawbacks of the fourth generation water heater are bulky system again leading to a large requirement of space for its installation, noisy operation leading to noise pollution, lengthened heating time resulting in consumption of a large amount of energy, a complicated maintenance procedure and the like
However, all the above mentioned generations of water heaters suffer from several drawbacks, such as, for example, release of air pollutants such as refrigerants, high power requirements, high cost of electric energy required, restricted usage during night or during poor weather conditions, complex installation procedures, requirement of large
amount of . space for opcialion. high operation costs, non-suitable for installation at some locations and the like.
Accordingly there exists a need in the art for a fifth generation water heater in order to overcome the above-mentioned shortcomings and drawbacks.

The power supply 185 is adapted to supply an AC voltage of about two hundred forty volts and a power of at least about one hundred twenty watts.
In one embodiment, when a user sets a temperature using the temperature control member 175, an activation signal is sent to the thermostat control board 160 that activates the switching power supply 165, the peltier tablet 145 and the fan 170. The fan 170 absorbs heat from the ambient air and transfers the absorbed heat to the coil 155. The heat absorbed by the coil 155 is transferred to the upper heat plate 140 via the lower heat plate 150 and the peltier tablet 145. The fan 170 further releases a cold air to the external environment via the coil 155. The cold air released by the fan 170 via the coil 155 is at a temperature of about 270°C which helps in keeping the surroundings of the hybrid hot water heater 100 cool. The cold air also helps to prevent the outer surface and a roof of the hybrid hot water heater 100 from getting overheated. Those of ordinary skill in the art will appreciate that the cold air released by the fan 170 can be utilized for various purposes, such as, for example, for cooling the surroundings of the hybrid hot water heater 100, thereby providing a multi-purpose system for heating water as well for
cooling environments. It is also appreciated that various adjustments can be made in the hybrid hot water heater 100 to release cold air having different temperatures to provide numerous advantages. The detailed operation of the hybrid hot water heater 100 is explained in FIG. 4 with reference to the following text.
In one embodiment, the hybrid hot water heater 100 further includes an overheat protection mechanism (not shown) for switching off a heating process in case of an emergency.

The upper heat plate 140 is directly coupled to the heat pipe 130 and the lower heat plate 150 is electronically coupled to the coil 155.
Referring now to FIG. 3, according to an alternate embodiment of the present invention, the hybrid hot water heater 100 may include a plurality of peltier tablets similar to the peltier tablet 145. The plurality of peltier tablets may heat a large quantity of water in a short span of time thereby making the present invention suitable for commercial and industrial applications in addition to domestic usage. Those of ordinary skill in the art will appreciate that the plurality of peltier tablets similar to the peltier tablet 145 can be arranged in various patterns- different from a pattern as herein illustrated. For example, but not limited to, the plurality of peltier tablets similar to the peltier tablet 145 can be arranged in a sidewise pattern such that each peltier tablet lies on a side of the other peltier tablet.
In an alternate embodiment, the power supply 1 85 can also be replaced by a 12 V battery. The use of the 12 V battery allows proper operation of the hybrid hot water heater 100 when there is reduced power or no power available. Furthermore, the hybrid hot water heater 100 consumes very less electrical energy as compared to conventional power heaters. For example, the hybrid hot water heater 100 consumes an electrical power of about 120 W to about 240 W whereas conventional water heaters consume the electrical power of about 2400 W to about 4800 W. Thus, a huge amount of electrical power is saved by a use of the hybrid hot water heater 100. Moreover, an efficiency of the hybrid hot water heater 100 is about 280 % to about 450 % whereas the efficiency of conventional water heaters is about 100 %. The efficiency referred herein is a ratio of an amount of water heated by the heater to an amount of electric energy consumed.
In one embodiment, the wall 100 of the hybrid hot water heater 100 is made up of polyurethane (Hereinafter "PU"). The PU employed in the hybrid hot water heater 100 provides a big advantage of preventing the hot water inside the hybrid hot water heater 100 from getting cold and hence once the twelve volt DC voltage is cut off, the hot water will remain hot for a longer period of time. It is observed that if the process oT heating water is not run, the hot water already present inside the hybrid hot water heater 100 remains hot for few days and the temperature of the hot water inside the hybrid hot water heater 100 is decreased by about 2°C every day.
In one embodiment, the coil 155 and the heat pipe 130 are made up of copper and / or aluminum pipes. The hybrid hot water heater. 100 is made up of stainless steel. Those of ordinary skill in the art will appreciate that the hybrid hot water heater 100 and its various components can be made using numerous elements, alloys and the like depending upon the requirements and similar other parameters.
In operation, a method for using a hybrid hot water heater 100 for heating water using ambient air includes: providing the hot water tank 105 having the wall 110 defining the water chamber 125 there within. The wall 110 includes the first opening 135, the water
inlet opening 1 1 5 and the hot water outlet opening 120. The method further includes providing and positioning the heat pipe 130 within the first opening 135 of the wall 1 10 of the hot water tank 105. The heat pipe 130 protrudes into the water chamber 125 from the wall 1 10 of the hot water tank 105.
The method further includes providing and directly coupling the upper heat plate 140 to the heat pipe 130. The upper heat plate 140 is mounted on the outer surface of the water chamber 125 of the hot water tank 105. The method further includes providing and directly coupling the peltier tablet 145 to the upper heat plate 140, providing and directly coupling the lower heat plate 150 to the peltier tablet 145, providing and electronically coupling the coil 155 to the lower heat plate 150 on either sides of the lower heat plate 150, providing and electronically coupling the switching power supply 165 to the peltier tablet 145, providing and electronically coupling the thermostat control board 160 to the switching power supply 160, providing and electronically coupling the fan 170 to the thermostat control board 160, and, providing and electronically coupling the power supply 185 to the thermostat control board 160.
The method further includes: providing and electronically coupling the thermostat 180 to the thermostat control board 160. The thermostat 180 is positioned within the hot water tank 105. The method further includes providing and wirelessly coupling the control member 175 to the thermostat control board 160. The control member 175 controls the temperature of the hybrid hot water heater 100.
FIG. 4 illustrates a method 400 for using the hybrid hot water heater 100 for heating water using ambient air, in accordance with an embodiment of the present invention. At step 402, the method 400 includes connecting the water inlet opening 1 15 of the wall 1 10 of the hot water tank 105 to the source of water 1 18. At step 404, the method 400 includes supplying electrical power from the power supply 185 to the thermostat control board 160. In one embodiment, the electrical power supplied from the power supply 185 to the thermostat control board 160 includes an AC voltage of about two hundred forty
volts. The ΛC voltage of about two hundred forty volts is transferred to the switching power supply 165 from the thermostat control board 160.
At step 406, the method 400 includes setting a desired temperature using the control member 1 75. Once a desired temperature is set, the switching power supply 165 converts the AC voltage of about two hundred forty volts into a twelve volt DC voltage. The twelve volt DC voltage activates both the peltier tablet 145 and the fan 170. The fan 170 absorbs heat from the ambient air and transfers the absorbed heat to the coil 155. The heat absorbed by the coil 155 is transferred to the upper heat plate 140 via the lower heat plate 150 and the peltier tablet 145. Now the peltier tablet 145 acts as a conductor to transfer all heat from the coil 155 to the upper heat plate 140 for the purposes of heating water via the heat pipe 130. Consequently, the temperature of the lower heat plate 150 becomes 0°C and the temperature at the upper heat plate 140 becomes double than an earlier temperature which is transmitted to the heat pipe 130 for heating up the cold water. Subsequently, the fan 170 again absorbs heat from the ambient air. The absorbed heat is transmitted to the coil 155. The coil 155 transmits the absorbed heat to the lower heat plate 150 to balance the temperature condition between the lower heat plate 150 and the upper heat plate 140. This recycle process continues till the desired temperature set at the step 406 and the cold water inside the water chamber 125 is heated continuously. The twelve volt DC voltage is cut off immediately when the desired temperature is achieved and the water heating process is terminated. The temperature of the hot water is monitored by the thermostat 180. In one embodiment, the water heating process can also be terminated before the desired temperature is achieved by the user with a help of the control member 175.
At step 408, the method 400 includes distributing hot water from the hot water outlet opening 120 of the wall 110 of the hot water tank 105.
FIG. 5 illustrates a method 500 for heating water using ambient air by the hybrid hot water heater 100, in accordance with an embodiment of the present invention. The
