Definitions
- a standard domestic water heater for home or small commercial use consists of a pressure tank containing water at line pressure (20 to 100 psi) and a heating device.
- the heating device can be an electric element gas or oil burner or heat exchanger transferring heat from another source.
- the pressure tank provides sufficient storage of heated water to satisfy peak demands. The heating device will not transfer heat fast enough to satisfy most demand rates but given sufficient time will bring the water in the tank back to the desired temperature.
- the vast majority of pressure tanks are made of steel and protected from corrosion by a glass or cement • lining. The corrosion protection is not complete and the life of a typical tank is about 10 years. The tank must withstand the line pressure safety and steel is the lowest cost way of getting the required structure.
- Tanks can be made much less expensively if they contain water at ambient (atmospheric) pressure.
- the present invention allows the line pressure to be transferred from the entering cold water stream to the leaving hot water stream without imposing this pressure on the walls of the tank.
- the pressure is contained in 2 small vessels with a combined volume that may be much less than one percent the volume of the tank. These vessels are constructed so that one can be filled with the heated water while the other discharges its contents to the hot water line and vise versa. They are cyclically operated by the pressurized entering fluid stream.
- Figure 1 is a modified sectional view of the complete system excluding elements not necessary for discussion.
- Figure 2 shows the system modified for solar heating.
- the system consists of the pressure transfer mechanism (PTM) 1, and storage vessel 2.
- the PTM is a fluid driven pump.
- Tank 2 contains a fluid 3 at temperature Tl.
- valve 7 is positioned such that fluid 4 enters chamber 8 at nominal pressure P driving piston 9 to the left and driving the fluid in chamber 10 past check valve 11 into pipe 12 to pipe 13.
- Piston 14 connected to piston 9 by rod 15, also moves left driving the fluid in chamber 16 past valve 17 and into the bottom of tank 2 via pipe 18.
- Piston 14 also draws fluid from tank 2 into chamber 19 via check valve 20.
- the fluid in chamber 12 is at nominally ambient pressure due to the open connection to tank 2.
- the fluid in chamber 19 is also at nominally ambient pressure due to the open connection to tank 2 and is at a temperature Tl.
- the fluid in chamber 8 is at temperature T2.
- valves 7 and 17 by the action of piston 14 causes fluid in at pressure P and temperature T2 to enter chamber 16 and allows the fluid in chamber 8 to exit via valve 17 and pipe 18 to tank 2 at ambient pressure.
- the higher pressure P in chamber 16 now drives piston 14 to the right and with it rod 15 and piston 9.
- the fluid in chamber 19 at temperature Tl is now taken almost to pressure P and forced through now open check valve 25 to pipe 26 and to pipe 13.
- the high pressure fluid at temperature Tl in pipe 13 is prevented from entering chamber 10 by valve 11 which is now closed.
- Valve 27 is now open allowing fluid 3 to enter chamber 10. at temperature Tl and ambient pressure.
- Piston 9 now moves to the right until it engages spring 28 causing the valves to shift back to the position shown and again reversing the direction of piston 9, rod 15, and piston 14.
- the advantage of this invention is that the pressure transfer system 1 can be made at lower cost than a pressure tank of over a given size.
- the cost advantage increases dramatically as the storage tank size increases.
- PTM 1 The action of PTM 1 is not perfect and certain inefficiences such as fluid bypassing valves 7 and 17 5 during switching will occur.
- PTM 1 is designed to " nominally pump more fluid from tank 2 than it receives from pipe 6. This is achieved by the slightly smaller displacement of chamber 8 and 19 due to the presence of rod 15.
- the diameter of rod 15 can by taylored to make 0 up expensed fluid bypass and same additional difference to be certain that- tank 2 will not become too full, any deficiency is made up for by float valve 29 which keeps tank 2 at the desired level.
- valve 7 is opened slightly before valve 17 and lever 22 and 23 is 0 used to reduce the force on spring 21 or 28 that is necessary to activate switching. This helps increase efficiency and reduce output pressure variation by minimizing the activating force required on piston 14 or 9.
- 5 Figure 2 shows PTM 1 and tank 2 with a solar pump 30 and solar collector 31.
- the use of an ambient pressure storage tank allows the implementation of a simple drainback solar system of high efficiency.
- the system is known as a drain back system because the fluid in the 0 collectors, usually water, drains back to a holding tank when the system is not in operation. This prevents heat loss and possible freezing.
- Solar pump 30 operated by motor 32 draws water from the lower part of tank 2 via pipe 33 and delivers it to collector 31 via pipe 34.
- collector 31 When collector 31 is filled the water flows back to tank 2 via pipe 35.
- Vent 36 is placed in pipe 35 to allow air to enter for drainback when pump 30 in not operating.
- a barrier 37 may be used to prevent undesirable mixing of the water from the top section with the water in the bottom section.
- Drainback systems in conjunction with pressure tanks usually utilize a separate ambient pressure storage vessel to hold the fluid utilized in the solar loop. Heat is. transferred from the solar heated fluid to the potable water via a heat exchanger.
- the heat exchanger being less than 100% effective raises the operating temperature of the solar collectors for a given temperature of potable water thus lowering the efficiency of solar collection.
- the heat exchanger, separate tank, and associated hardware significantly increase the cost and complexity of the system.
- the system of this invention is significantly more efficient, simpler, and lower in cost.
