Definitions

  • the submitted invention describes a heating system with a heat pump that collects heat energy from water, which is pumped from the location of its occurrence by way of pumping equipment In this situation underground water is preferentially used as a source of heat energy for heat pumps; the water is either from a drill hole and/or from a well.
  • the heating system with heat pump serves to heat homes, flats, buildings and other areas. Water that is pumped by gravitational pumping equipment can simultaneously be used to supply the house. Implementing this type of heating system is possible in those situations in which there is an adequate water source.
  • thermodynamic heating with a heat pump natural renewable heat energy from a selected primary source is normally collected and over-pumped to the secondary side of the system where produced heat and/or cold is given and utilized for the heating and/or cooling of space and/or for the heating of water.
  • Heat pumps that utilize heat energy from underground water are generally considered the most heating cost-effective. Thanks to the constant temperature of underground water it achieves a stable heating output throughout the year and a higher coefficient of performance COP than other heat pumps.
  • Gravitational suction pumping equipment and the gravitational suction pumping method that is being presented serves mainly to pump underground water from drill holes, to pump surface water, to pump liquids in various applications and generally to secure a flow of liquids through tubing and for the creation of a liquid gradient.
  • Gravitational suction pumping of liquids eliminates the consumption of direct forms of electrical energy in the course of the pump cycle.
  • Various electric pumps utilize fed-in electricity from distribution networks or electricity produced by alternative sources as a direct form of electric drive.
  • the pressure pumping action in the pumped liquid is predominantly created by a compressor with electric drive.
  • the gravitational suction pumping of liquid method eliminates the disadvantages that accompany the structure of current pumps as well as securing an adequate pumping performance for the application in question. In the course of pumping there is no consumption of paid-for energy.
  • thermodynamic heating systems or in other words heat pumps collect so-called low-potential heat from the air, from the soil, ground or from a water.
  • Heat pumps collecting heat from air whose temperature changes every day is the least economic. For operation they consume the most electrical energy for the drive of refrigerant compressors and for the drive of evaporator fans. These pumps work with a significantly variable compressor load.
  • Geothermic heat pumps that collect heat from the soil are operationally more economical while those heat pumps collecting heat from underground or waste water are considered the most economical.
  • Each type of heat pump can be also equipped with solar support, which shifts the efficiency of the system while maintaining the differences of the specific preferential effect of the selected primary source.
  • a disadvantage of traditional pump systems is its consumption of electricity, which is normally paid-for energy, and the moving parts within the pump system, which can wear out in time.
  • various constructions of pump equipment have been developed; for example pump equipment based on so-called pulse pumps that have two closures within the pump chamber that respond to the pressure of the surroundings. By opening one of the closures a certain amount of pumped liquid is extruded into outlet tubing while the necessary amount of pressure enters the pump chamber when the second closure is opened.
  • the pressure effect of liquid outside the pump chamber can be natural or created.
  • the natural pressure effect of water includes effect created by the energy of falling water or as a result of its own pressure in an underground groundwater body which can be drilled.
  • Another solution is positioning two or more pistons at a distance from each other on a common suspender.
  • the suspender runs from the drill hole to the surface where it is attached to a manual or motor drive, which invokes lifting and the release of pistons within drill hole tubing.
  • Side tubing is connected to the section or sections between the pistons in order to transport pumped liquid to the surface.
  • a disadvantage is the necessity of permanent participation of drive with each pumping lift leading to a higher consumption of energy when securing the pumping cycle.
  • Other well-known equipment includes micro-pumping equipment; in this case heating bodies invoke the energy for the movement of liquid by heating gas in the pump chamber above the level of pumped liquid.
  • Appropriately positioning cooling within the pump chamber structure invokes a difference in temperatures and pressures above a level, which brings on the rotation of gas within the chamber. Liquid flows into the chamber by way of an inlet and flows out by an outlet. Other pumping equipment heats liquid in a membrane-divided pump chamber. The necessity of subsequent supply of heat energy and the small pumping power range are considered its disadvantages.
  • Electric submersible pumps are used in those heat pump systems that collect heat energy from pumped underground water in order to heat premises thanks to their ability of achieving an adequate flow. These submersible pumps are appropriate for pumping thin and non-aggressive liquids that do not contain solid particles or fibers.
  • the pumps normally have 3-phase motors with an encased rotor, a cover to prevent the intrusion of sand, bearings greased by the pumped liquid and a membrane for the leveling of pressures. They secure the water flow within the evaporator where heat energy from the water is transferred to the cooling circuit of the heat pump.
  • the electric input of the equipment for pumping water, or to be precise for maintaining lift and flow, is attributed to the total input of the system and therefore decreases the COP of the heat pump and the efficiency of the entire heating system.
  • the heating system selected to transfer the produced heat also influences the efficiency of the entire heating system.
  • the transfer of heat, which does not have any demands for further electric input within the heating system, is the most efficient in energetic terms.
  • Electric input in heating systems is associated with the drive of fans or the drive of liquid-circulating pumps.
  • the current technical status of heat pumps with underground water utilize water pumping equipment that can secure water flow of about 2,3 mThour while using a so- called low-temperature heating system with a temperature gradient of 30/35 0 C to transfer the produced heat.
  • Traditional low-temperature heating systems are equipped with at least one electric circulating pump offering a total electric input of up to 200 W.
  • the temperature of underground water in Central Europe is about +8 to + 12 0 C.
  • each type of evaporator and water pump has maximum allowable values available: the sand content in 1 m 3 of pumped water, the size of suctioned particles, water temperature, water pH, and ratio of Fe, NH 3 , Cl, H 2 SO 4 , Mg and salt.
  • Traditional pumping equipment with moving parts within its construction can operate for a shorter time; the equipment's life cycle is also limited.
  • thermodynamic compressor generator with the outside and/or inside location of the thermodynamic compressor generator as well as with an outside and/or inside location of gravitational suction pumping equipment in accordance to this invention.
  • This system of heat production and the pumping of water are more efficient, are operationally more economic and offer an easier construction.
  • Gravitational suction pumping serves to pump underground water and/or other liquids from ground drill holes, to pump surface water, to allow for the pumping of liquids in various applications and the flow of liquids within the tubing.
  • the pumped liquid is collected in the pumping chamber of a partial or completely elastic construction, where the amount of collected liquid and the elastic pumping chamber can be expressed as a body of mass m.
  • free of charge physical effect is secured by the actual pumping process in which the elastic parts of the pumping chamber undergo elongation.
  • the pumping chamber is firmly secured and/or hung while the elongation, or to be precise the elastic enlargement of its volume, invokes a vacuum and suction in the top part of the chamber in which liquid is sucked via the tubing from its primary collecting site. After opening at least one opening in a part of the pumping chamber, this pumped liquid flows out while maintaining the suction effect in the top part of the pumping chamber.
  • the suction effect for the flowing of liquids can be easily described by the following example in which the liquid enters the mouth of the transport tubing.
  • Tubing is led into the collecting space below the level of pumped liquid. It is directed upwards above the level and is bent after reaching a certain height and the desired direction.
  • a suspender is fixed to the piston, which is in the top part of the tubing. The suspender is led via the pulley; a weight of a mass of m is connected to the end of the suspender. Following the hanging or loosening of the weight, the effects of gravitational forces take effect starting with the mass of the weight via the pulley to the piston.
  • the gravitational force of m influences the piston, resistances and frictions are neglected.
  • the liquid follows the movement of the piston and weight to a certain distance within the tubing. Separation occurs after a certain distance and after a certain time; in other words the liquid ceases to follow the movement of the piston and weight. This occurs after a decrease in pressure on the piston according to the degree of pressure of suctioned vapors.
  • the creation of the suction effect is influenced not only by the weight but also by the mass of the collected liquid. If the pumped liquid is collected in an appropriately fixed container, the volume of the liquid in the container creates the gravitational force.
  • the liquid mass m is given by the product of the liquid volume in the container V and the density of the liquid p.
  • In the bottom part of the container there is an openable closure or outlet tubing with the same kind of closure.
  • a container of a cylindrical shape, which is filled with liquid, is firmly attached.
  • a balloon or elastic bag is non-permeably attached at the top part.
  • the second condition concerning the hydraulic continuity of all parts must be respected as well; this occurs as a result of the leading in of at least one end of connected tubing below the level of pumped liquid and another end into the top part of an elastic pump chamber and filling all of these parts with the pumped liquid.
  • the driving power is developed as a result of a dynamic effect in which the elastic bottom part of the pump chamber is released for free fall; prior to this the chamber contains a smaller volume.
  • the top part of the pump chamber is attached. The gravitational force is created by the mass of the elastic top part of the pump chamber and the mass of the pumped liquid, which is in the chamber.
  • All forms of resistance, friction and mainly the stiffness of the elastic parts of the pump chamber which can be introduced as the stiffness of protracted and/or compressed elastic body, work against the effects of gravitational forces.
  • the stiffness of elastic bodies is expressed by the ratio of the magnitude of forces acting on the elastic body or to be precise on the body of mass m to the difference in lengths of the elastic body before and after protraction and/or before and after compression.
  • the stiffness of the elastic body is a material constant, which determines the resistance of the elastic body against changes in its shape and size.
  • Elastic parts of the pump chamber will have elastic properties, which will comply under the given conditions.
  • the pumping equipment is completely filled with the pumped liquid.
  • the pump chamber is in the status and position having a smaller and filled-up volume. Sudden loosening leads to an increase in volume and to the creation of suction effect or in other words to the creation of a vacuum in the top part as well as leading to the sucking of a certain amount of liquid into the pump chamber while maintaining the suction effect.
  • Opening at least one closure at an appropriate location in the filled-up body of a pump chamber leads to the flow of liquid out of the pump chamber.
  • the liquid starts flowing from the collection site via the transport tubing into the construction of the pump body; it then flows out through the opened opening. After a certain time, it is possible to designate the flow by way of pumping equipment as relatively steady when the necessary vacuum is maintained.
  • Liquid is being sucked at one end and flows out at the other end by way of over-pumping. There is waste disposal space below the outlet closure. Above the level of the pumped liquid there is atmospheric pressure or the liquid is over-pressured.
  • the overpressure at underwater drill holes could have been created by the saturation pressure under the firm closure or after sealing off the drill holes.
  • the amount of time to maintain the desired suction effect depends on the quality of the hermetic design of the entire sector of transport tubing, the construction of the pump chamber including inlets, outlets and with the setting of all fittings, control elements of the pumping system.
  • the suction effect is also influenced by the pumped liquid, which always contains a certain amount of gases and impurities and overcomes the friction and resistance it faces on route from the collecting site to its opening.
  • the impulse invoking the suction effect will be repeated in very long intervals.
  • the pumping equipment is significantly more effective that the current systems.
  • Invoking an impulse to produce and maintain the suction effect in an the elastic pumping chamber is possible in these ways or in these combinations: by utilizing mechanics of elastic bodies, and/or motor drive with an electromotor or with a combusting motor, and/or the effects of compressed gas by a compressor, and/or hydraulic effects, and/or magnetic forces, and/or heat effects, and/or pyrotechnic effects, and/or chemical effects, and/or wind effects, and/or human power.
  • the example found in this invention describes the design of the heat pump with underground water, which is sucked by a suction chamber; as a result of gravitation, water flows around and through an evaporator where heat is released to the refrigerant and the initial pumping effect of the suction chamber is created by a pressurized effect from the outlet of the refrigerant compressor system.
  • the initial impulse to invoke sucking within the pumping chamber is most commonly provided by electric remote control and/or mechanical influence, and/or by hand-manually.
  • the entire pumping equipment including a pumping-suction chamber consists of at least one transport tubing that is led into the pumped liquid whereas this tubing further consists of at least one integral continuous sector of tubing, which is straight or shaped in some places and can have at least one closeable branching and/or opening and/or T-piece, and other control elements within the tubing including a backflow valve and/or closure and/or sensor for measuring flow and/or pressure and/or temperature; there is at least one voluminous body or in other words pumping-suction chamber is directly and/or via a suction head attached to the transport tubing and/or onto this branching.
  • the elasticity of the construction of this pumping-suction chamber allows for a change of its volume.
  • the volume of the aspirating chamber is completely/or partially filled with the pumped-sucked liquid, which flows via the transport tubing from the location of its leading in the collecting site.
  • the movement and flow of this liquid via transport tubing is created and secured by suction effect or in other words vacuum, which is created preferentially in the top part of the pumping-suction chamber thanks to gravitational forces, or more precisely terrestrial gravitation, which changes the shape and volume of at least one elastic part of the pumping-suction chamber.
  • the pumping-suction chamber and/or transport tubing is firmly anchored and/or hung and/or propped at least at one location.
  • the pumping-suction chamber contains a smaller volume.
  • the initiating impulse leads to the invocation of an impulse; during this time the chamber changes its volume due to the creation of vacuum and suction.
  • the chamber's walls are made of elastic material, and/or the walls of the elastic part of the chamber can contain at least one elastic element, and/or this plastic element can be inside, and/or outside its own walls and the location of the actual pumping-suction chamber.
  • extension of the elastic belt is equivalent to the compression of ideal gas and unloading is equivalent to its expansion.
  • the simplest construction for invocation of the aspirating-suction effect can be produced from an elastic bag. There is a closeable outlet. If the bag is elastic enough, the weight of the liquid will bring on extension and to invocation of suction effect in the top part.
  • the weight of the liquid in the bag can be increased by using materials with a higher density for the body of the bag. For example the density of metals is eight times higher than that of water.
  • suction chambers are when one part of the volumic tank is rigid and the other is elastic or when the elastic part is positioned between two rigid parts.
  • the elastic part of a pumping chamber can be of varying stiffness. If the elastic part is positioned between two rigid parts, the bottom rigid part could be considered heavy due to consisting of a material of a higher density than that of the pumped liquid.
  • the elastic materials used in the structure of elastic parts of pumping-suction chambers are mainly materials and/or their combinations based on natural rubber or synthetic rubber or elastic sandwich materials stemming from multi-layers of the same material or different materials, structures with carbon fibers, with fiberglass, elastic materials such as metals in springs, and other materials.
  • an elastic structure can be developed by way of a gas spring and/or liquid spring.
  • At least one pumping-suction chamber can be located in waste disposal drill holes, and/or in the suction drill hole, and/or inside the premise being supplied, and/or on the premises, and/or only outside above ground level, and/or submerged below ground level.
  • the gravitational suction pumping method being presently introduced operates independently mainly to pump underground water and/or other liquids from terrestrial drill holes, as well as pumping surface waters; the method allows for liquid to be pumped in various ways, for liquid to flow through tubing as well as allowing for the creation of a liquid gradient.
  • the principle of gravitational suction pumping of liquids is also evident from the examples of its uses and from the figure section of this invention.
  • a suction tube When water is pumped from drill holes, there is at least one suction tube led into some sort of weight; for example into a flange at an installation depth of 0.5 to 1 meter below the depth of the dynamic water level, which is referred to as a so-called safety reserve.
  • a water-level switch and water- level electrodes can be installed in the source drill holes to ensure early alarm detection and if the heat pump generator is included in the system to allow it to be switched off.
  • Suction tubing with weight is lowered into the drill hole on a steel or plastic cable whose end is attached in the drill hole head with the help of a cable connecting device. After this the pumping drill hole is secured and sealed. Up to its connection to the pumping-suction chamber, transport tubing is led through a frost protection zone and/or is heat insulated.
  • an advantage of the pumping equipment is that traditional pumps with complicated constructions, with electromotors whose motors are encapsulated and with bearings or with air compressors are not used. Another benefit is the very small consumption of external energy that is only supplied for the primary creation of suction at the start of the pumping cycle or in other words when the equipment is started.
  • another advantage is the fact that the movement of pumped liquid via transport tubing into the elastic suction chamber takes place only due to territorial gravitation or more precisely due to no charge gravitational forces.
  • Another advantage of this kind of pumping equipment is the fact that externally paid energy is not utilized during pumping.
  • Another advantage is that it is usually possible to utilize only one elastic pumping chamber with simple construction when implementing the movement of pumped liquid.
  • Another advantage is the fact that pumping equipment according to this invention is more resistant to impurities contained in crude underground water. Another advantage is the movement of the elastic structure of pumping chambers without other moving parts and pistons within the pumping equipment. Another advantage of utilizing its own refrigerant compressor system to invoke a start of suction is that it is not necessary to set any other external automatic drive. Other advantages and assets will be experienced by experts in the field, who read about the other connections and specification in detail and who comprehend them.
