  • 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 m 3 /hour while using a so-called low-temperature heating system with a temperature gradient of 30/35° 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° 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 , C 1 , H 2 SO 4 , Mg and salt.

  • Gravitational suction pumping serves to pump underground water and/or other liquids and fluids from ground drill holes, to pump surface water, to allow for the pumping of liquids and fluids in various applications and the flow of fluids within the tubing, channels and bodies.
  • 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 ⁇ g. 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.

  • 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.

  • 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 all current systems.

  • 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 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.

  • 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.

  • 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 fluid via transport tubing into the elastic suction chamber takes place only due to territorial gravitation or more precisely due to no charge gravitational forces.
