FRICTIONAL HEAT ENERGY WATER HEATING SYSTEM
This invention relates to development in the systems used for heating water, frictional energy is used to heat water instead of other conventional sources of energy.
The present invention relates to a system specifically used for heating water with help of frictional energy. The frictional heat energy is generated by tapping the motions. This system is mainly designed for public places with high footfalls such as shopping malls, railways stations etc.
The present invention Frictional heat energy water heating system describes a system which comprises of a supply tank which serves as a input unit supplying water, heat exchanger which comprises of number of frictional heat energy generators acts as a processing unit which heats up the water, storage tank acts as a output unit where heated water is stored. The temperature sensor along with embedded system constitutes the feedback mechanism which governs the whole system.
As per previous arts of heating water the heating system normally uses fuel or electrical energy to heat the water in the system. These conventional systems of heating water had certain limitations and drawbacks. The systems using fuel energy normally rely on fossil-fuels (hydrocarbons) which are fast becoming depleting natural resources. Further the combustion products of fuels add up to air pollution. On the other hand electrical system for heating water cannot be operated in absence of electricity and making them unreliable in areas where electricity is still a scarcity.
New approaches taken were to provide water heating system running on renewable source of energy such as solar energy as in US patents 3989032, 4397294, 4453534, 5537990 etc. Although all of these systems have proved to be quite successful they had a common drawback of depending on solar energy. The solar energy may or may not be available at any given instant. Thus making this

system worthless in case of unavailability of solar energy. So the objective of the present invention is to provide an eco-friendly system to tap an alternative source of energy known as frictional energy.
On the other hand various other water heating systems have developed for heating water by improving the efficiency of fuel, electrical water heating systems. The fuel energy heating system uses the fuel energy of fuels by burning them. Where as electrical heating system works on the heating effect of current. The efficiency of these systems has drastically increased from their predecessors. Although there has been considerable increase in the efficiency, yet these systems were not able to completely overcome there drawbacks. Major one's being dependency on non-renewable source of energy and pollution.
The basic objective of this Frictional heat energy water heating system is to provide a system which overcomes the problems of above said systems described as prior arts for water heating system. Present invention comprises of a supply tank provided over an elevated section, a set of pump to force and circulate water in heat exchanger. The supply tank serves as a source of water. It is placed at an elevated section so as to provide a constant water head on suction end of the pump, to prevent any loss in suction due to air trap. The supply pump forces a fixed quantity of water in heat exchanger at desired rate. Heat exchanger comprises of a number of frictional heat energy generators. Each of frictional heat energy generators taps the motion and converts it into frictional heat energy.
In the present invention water is heated in heat exchanger which comprises of number of frictional heat energy generators. The water after being heated in heat exchanger is passed on, a temperature sensor mounted on the pipe is used to check the temperature of water. Until the desired temperature is reached water is circulated in heat exchanger using circulating pump and fresh supply of water from supply tank is stopped. Once the desired temperature of water is reached

water is drained to storage tank and fresh water is pumped in from supply tank and same process is repeated. The synchronized operation of different pumps and solenoid valve used in the system is achieved by using an embedded system. The embedded system using driver circuits controls and synchronizes the operations of different pumps and solenoid valves.

Detailed description of the preferred embodiments:
The present invention Frictional heat energy water heating system describes a system which comprises of a supply tank which serves as a input unit supplying water, heat exchanger which comprises of number of frictional heat energy generators acts as a processing unit which heats up the water, storage tank acts as a output unit where heated water is stored. The temperature sensor-along with embedded system constitutes-the feedback mechanism which governs the whole system.
With reference to detailed description of the described drawing, the overall system is indicated as line diagram in the entry figure 1, by reference character 1.

It includes supply tank 1, supply line solenoid valve 2, supply pump 3, heat exchanger 4, temperature sensor 5, circulating line solenoid valve 6, circulating pump 7, output line solenoid valve 8, output pump 9, storage tank 10 and isolating solenoid valve 11. The supply line solenoid valve 2, supply pump 3, circulating line solenoid valve 6, circulating pump 7 and isolating solenoid valve 11 constitutes water supplying and circulating unit. The output line solenoid valve 8 and output pump 9 constitutes the drain unit.
With reference to figure 2, it shows an individual unit of frictional heat energy generator. It includes 3 motion tappers 12, 3 force magnifiers 13, force transmitter 14, upper spring 15, moving block 16, lower spring 17, outer cover 18, separating plane 19 and hydraulic fluid 20.
This whole system is placed such that the frictional heat energy generator comes under the covering of floor which is considered to be non rigid and the motion tappers are on the upper end just below the floor,
The supply tank 1 is placed at an elevated platform to provide a continuous water head on the suction side of the supply pump 3. When system is started on the embedded system opens the supply line solenoid valve 2 where as closing the isolating solenoid valve 11 along with it switches on the supply pump 3 forcing a fixed pre defined quantity of water in the system i.e. is supply line solenoid valve 2 is opened for a fixed duration of time. Heat exchanger 4 comprises of number of frictional heat energy generator. When water enters the heat exchanger it surrounds the outer cover 18 of frictional heat energy generator. When a force is applied on motion tappers 12 i.e. when a body with mass such as human or any other thing passes over the floor a force is applied on the motion tappers 12 due to weight of the body. The motion tappers 12 in turns press the hydraulic fluid 20 inside the force magnifiers. As a result a magnified force is passed on the upper end of force transmitter 14. The force is magnified according to Pascal's law. The Pascal's law is applied between the motion tappers 12 and force transmitter 14. The force transmitter 14 on receiving the force presses down the upper spring 15 which in turn presses down the moving block 16. The moving block 16 moves down rubbing against the outer cover 18 thus creating frictional heat energy as a

result of friction. The surfaces of the moving block 16 and outer cover 18 are made rough to maximize the frictional force. This energy is absorbed by water surrounding the outer cover 18 which results in increase of temperature of water.
The moving block 16 while moving down presses the lower spring 17. The lower spring 17 compresses and stores the energy which it imparts back to moving block 16 forcing it to move up again while rubbing the outer cover 18 thus creating frictional heat energy. This is absorbed by the surrounding water which in turn is heated again. The moving block 16 again moves up again pressing upper spring 15 which repeats the process but it dampens soon. Each time a body with mass passes over the floor beneath which motion tappers 12 are placed the whole process is repeated.
In same manner other frictional heat energy generators heats up the surrounding water. When water comes out of the heat exchanger 4 it flows in the pipe unto which a temperature sensor 5 is mounted at a specified location. The temperature sensor 5 sends a signal to embedded system when desired temperature for water has reached. Until the desired temperature is reached embedded system opens the circulating line solenoid valve 6 and puts on the circulating pump 7 along with this it opens the isolating solenoid valve 11 which was kept open during the period water was being pushed in the system. The supply pump 3 is also put on to again push water back into the heat exchanger 4 and water is heated again in the same process as stated above.
When the water has reached the desired temperature the temperature sensor 5 sends a signal to embedded system which in turn closes the circulating line solenoid valve 6, isolating valve 11, circulating pump 6 and supply pump 3. Along with this it opens output line solenoid valve 8 and puts on the output pump 9 to drain the heated water to the storage tank 10. The system is supplied with fresh water once the heated water has been drained to storage tank 10 to maintain the desired level of water in system. All the pipe lines used in the system are coated with the insulating material to minimize the loss of heat. This process is used to heat water in supply tank 1.
