  • BRIEF SUMMARY OF THE INVENTION
  • Briefly described, in a preferred embodiment, the present invention overcomes the above-mentioned disadvantages and meets the recognized need for such an apparatus by providing a kinetic energy heat pump and method for heating and cooling air, and more specifically a kinetic energy heat pump comprising a nozzle, a tube and a diffuser having a separating baffle disposed therewithin, wherein the tube comprises a radial bend, and wherein gases accelerated to near sonic velocity travel around the radial bend and compress outward to form a thermal gradient.
  • Accordingly, one advantage of this apparatus is that it heats and cools air without utilizing a heat exchanger, and thus does not incur problems associated with heat exchangers, such as, the temperature differential across the exchanger surface, or the utilization of toxic refrigerants and/or the possibility of refrigerant leakage.
  • According to its major aspects and broadly stated, the present invention in its preferred form is a kinetic energy heat pump comprising a tube having a radial bend. The radial bend preferably comprises between approximately ninety and one hundred and eighty degrees, but could be less than ninety or more than one hundred and eighty degrees so long as reasonable separation of thermal streams can be accomplished. The kinetic energy heat pump further comprises a nozzle, a diffuser and two outputs, wherein the nozzle accelerates gas to near sonic, but subsonic, velocities, and wherein the two outputs comprise a hot gas output and a cold gas output.
  • The kinetic energy heat pump accelerates gases around the radial bend and compresses the gases outward to form a thermal gradient. The thermal gradient is formed by action of centrifugal force on the gases, wherein gases that are compressed more have increased temperature, and wherein the thermal gradient is divided via a separating baffle into a fraction having hot gases relative to input temperature and a fraction having cool gases relative to input temperature.
  • The kinetic energy heat pump further provides a method of heating and cooling air comprising: obtaining a kinetic energy heat pump having a tube with a radial bend, a gas source, a blower, an adjustable separating baffle and two outputs. Gas is accelerated with the blower and nozzle combination, wherein the accelerated gas flows around the radial bend and into a diffuser with a baffle that divides the gas into hot and cold streams. The method of heating and cooling air further comprises extracting the cold stream from one of the two outputs, extracting the hot stream from the other of the two outputs and adjusting the baffle to select the temperature of the hot and cold gas streams.
  • Additionally, the kinetic energy heat pump comprises a blower, a nozzle, a tube having a bend a diffuser and a separating baffle, wherein the blower and nozzle combine to produce near sonic, but subsonic, flow around the bend in the tube. The kinetic energy heat pump further comprises a cold gas fraction and a hot gas fraction, wherein the separating baffle selectively controls the temperature of gases in the hot and cold gas outlets.
  • More specifically, the present invention is a kinetic energy heat pump comprising a blower, a nozzle, a tube with a bend, a diffuser, a separating baffle, a cold channel and a hot channel. The blower is in fluid communication with the nozzle, the nozzle is in fluid communication with the tube and the tube is in fluid communication with the diffuser, wherein the separating baffle is disposed within the diffuser. The diffuser is in fluid communication with the cold channel and the hot channel. As discussed more particularly hereinbelow, the separating baffle pivots at either end, wherein the baffle is selectively adjusted to modify the quantity of cold gas molecules and hot gas molecules that travel through a cold and a hot channel, respectively, wherein selection of the quantity of molecules selects the temperature of the gas steams passing through the hot and cold channel.
  • The blower introduces gas molecules into the kinetic heat energy heat pump, wherein the blower comprises an outlet end that enters the nozzle. The nozzle comprises an inlet, a throat and an outlet, wherein the end of the blower is in fluid communication with the inlet of the nozzle.
  • The tube comprises a first end, a radial bend and a second end, wherein the outlet of the nozzle is in fluid communication with the first end of the tube. Further, the second end of the tube is in fluid communication with the diffuser, wherein the diffuser has a separating baffle disposed therewithin. Additionally, the end of the diffuser is in fluid communication with the cold channel and the hot channel, wherein the cold channel comprises a cold inlet and a cold outlet, and wherein the hot channel comprises a hot inlet and a hot outlet.
  • In use, the blower introduces the gas molecules into the nozzle, wherein the nozzle accelerates the gas molecules to near sonic, but subsonic, velocities. The accelerated gas molecules exit the nozzle and enter the first end of the tube, traveling into the radial bend, wherein the tube comprises an outer radius and an inner radius. As the gas molecules travel around the radial bend, centrifugal force compresses the gas molecules outwardly against an outer wall of the tube, thereby heating the gas molecules. Similarly, the gas molecules expand near the inner wall to form a cold stream of gas molecules, wherein the cold gas molecules are disposed predominately near an inside wall of the tube. The hot gas molecules and the cold gas molecules travel through the second end of the tube and into the diffuser. The hot gas molecules enter the hot side of the diffuser, wherein the hot side is in communication with the outer portion of the bending tube, and wherein the diffuser decelerates the hot gas molecules back to ambient pressures. Similarly, the cold gas molecules enter the cold side of the diffuser, wherein the cold side is in communication with the inner portion of the bending tube, and wherein the diffuser decelerates the cold gas molecules back to ambient pressure. The separating baffle subsequently separates and directs the hot gas molecules and the cold gas molecules into the hot channel opening and the cold channel opening, respectively. The hot gas molecules subsequently travel through the hot channel and exit via the hot outlet. Likewise, the cold gas molecules travel through the cold channel and exit via the cold outlet.
  • The kinetic energy heat pump may be particularly understood in terms of the following equations: Newton's Second Law of Motion states F=ma, wherein F=force, m=mass and a=acceleration. Also, P=F/A, wherein P=pressure, F=force and A=area. Lastly, the acceleration due to centrifugal force is given as a=v2/r, wherein a=acceleration, v=velocity and r=radius. Solving for F, results in F=PA. Substituting for F, results in ma=PA. Solving for P and substituting for a, results in P=mv2/rA for gaseous fluids.
  • Additionally, it is assumed that the working fluid is ideal, although the system will work with non-ideal gaseous fluids. Thus, equations about ideal gas may be applied, wherein PV=mRT, and wherein P=pressure, V=volume, m=molecular mass, R=ideal gas constant 53.34 ft-lbf/lbrm-°K and T=temperature. Solving for T and substituting for P, equation T=(V/R) (v2/rA) is obtained, wherein T is a function of radius r of the tube. Assuming A is constant, taking the derivative of T and r, the following equation is obtained, To=[Ti 2+v2/R (ln(ro)−ln(ri))]1/2, wherein To is the temperature of the gas stream at ro, and wherein Ti is the temperature of the gas stream at ri.
  • An example of numerical values associated with the kinetic energy heat pump is shown in Example 1. For example, if outer radius of the tube is four (4) inches and the inner radius of the tube is two (2) inches, and the gas molecules exit the nozzle at a velocity of approximately 1129 ft/sec, then the temperature of hot gas molecules at the outer radius is 78.4° F. and the temperature of gas molecules at the inner radius is 75° F.

  • FIG. 2 is a cross-sectional schematic view of a kinetic energy heat pump; and
  • FIG. 3 is a perspective view of an outlet of a kinetic energy heat pump, showing a pivoting baffle.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
  • In describing the preferred embodiment of the present invention, as illustrated in FIGS. 1-3, specific terminology is employed for the sake of clarity. The invention, however, is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner to accomplish similar functions.
  • Referring now to FIG. 1 kinetic energy heat pump 10 comprises blower 20, nozzle 30, tube 40, diffuser 50, separating baffle 60, cold channel 70 and hot channel 80. Blower 20 is in fluid communication with nozzle 30, nozzle 30 is in fluid communication with tube 40 and tube 40 is in fluid communication with diffuser 50, wherein separating baffle 60 is disposed within diffuser 50. Diffuser 50 is in fluid communication with cold channel 70 and hot channel 80. As discussed more particularly in FIG. 3 hereinbelow, separating baffle 60 comprises pivot 61, wherein pivot 61 is selectively adjusted via rod 64 to modify the quantity of cold gas molecules 23 and hot gas molecules 22 that travel through cold and hot opening 71, 81, respectively by positioning separating baffle 60.
  • Still referring to FIG. 1, blower 20 introduces gas molecules 21 into kinetic heat energy heat pump 10, wherein blower 20 comprises end 22. Nozzle 30 comprises inlet 31, throat 32 and outlet 33, and wherein end 22 of blower 20 is in fluid communication with inlet 31 of nozzle 30.
  • Tube 40 comprises first end 41, radial bend 42 and second end 43, wherein outlet 33 of nozzle 30 connects to first end 41 of tube 40. In one embodiment, tube 40 comprises approximately a ninety-degree bend. It will be recognized by those skilled in the art that tube 40 could comprise angles greater or less than ninety-degrees without departing from the spirit of the present invention.
  • Second end 43 of tube 40 is in fluid communication with diffuser 50, wherein diffuser 50 comprises inlet 51 and outlet 54, and wherein diffuser 50 comprises separating baffle 60 having top 62 and bottom 63. Additionally, outlet 54 of diffuser 50 is in communication with cold channel 70 and hot channel 80, wherein cold channel 70 comprises cold opening 71 and cold outlet 73, and wherein hot channel 80 comprises hot opening 81 and hot outlet 83.
  • Referring to FIGS. 1-2, in use, blower 20 introduces gas molecules 21 into nozzle 30, wherein nozzle 30 accelerates gas molecules 21 to near sonic, but subsonic velocities. Accelerated gas molecules 21 exit nozzle 30 and enter first end 41 of tube 40, traveling into radial bend 42, wherein radial bend 42, and wherein tube 40 comprises outer radius ro and inner radius ri. Kinetic energy heat pump 10 has been tested at radial bends 42 comprising approximately between ninety and one hundred and eighty degrees. Bends 42 of less than ninety or more than one hundred and eighty degrees could be utilized so long as adequate thermal separation results.
  • As gas molecules 21 travel around radial bend 42, centrifugal force compresses gas molecules 21 outwardly against outer wall 44, thereby heating gas molecules 22. Similarly, gas molecules 21 away from outer wall 44, being less compressed, form cold gas molecules 23, wherein cold gas molecules 23 are disposed predominately near inside wall 45 of tube 40. Hot gas molecules 22 and cold gas molecules 23 travel through end 43 of tube 40 and into diffuser 50. Hot gas molecules 22 enter inlet 51 of diffuser 50, wherein diffuser 50 decelerates hot gas molecules 22. Similarly, cold gas molecules 23 enter inlet 51 of diffuser 50, wherein diffuser 50 decelerates cold gas molecules 23. Separating baffle 60 subsequently separates and directs hot gas molecules 22 and cold gas molecules 23 into hot opening 81 and cold opening 71, respectively. Hot gas molecules 22 subsequently travel through hot channel 80 and exit via hot outlet 83. Likewise, cold gas molecules 23 travel through cold channel 70 and exit via cold outlet 73.
  • TABLE 1
    F = ma (Equation 1)
    P = F A (Equation 2)
    a = r 2 r (Equation 3)
    F = PA (Equation 4)
    ma = PA (Equation 5)
    P = mv 2 rA (Equation 6)
    PV = mRT (Equation 7)
    T = V R r 2 rA (Equation 8)
    Then, dV = Adr (Assume A = constant)
    T o = [ T i 2 + v 2 R - { ln ( r o ) · ln ( r i ) } ] 1 / 2 (Equation 9)
  • FIG. 2 may be particularly understood in terms of equations as shown in Table 1. Newton's Second Law of Motion states F=ma (Equation 1), wherein F=force, m=mass and a=acceleration. Also, P=F/A (Equation 2) wherein P=pressure, F=force and A=area. Lastly, centrifugal force is given by a=v2/r (Equation 3), wherein a=acceleration, v=velocity and r=radius. Solving for F in Equation 2, F=PA (Equation 4) is derived. Substituting Equation 1 for F in Equation 4, ma=PA (Equation 5) is derived. Solving for P in Equation 5 and substituting Equation 3 for a, results in P=mv2/rA (Equation 6).
  • Additionally, it is assumed that the working fluid is ideal, although the device will work with non-ideal gaseous fluids. Thus, equations about ideal gas may be applied, wherein PV=mRT (Equation 7), and wherein P=pressure, V=volume, m=molecular mass, R=ideal gas constant 53.34 ft-lbf/lbm-° K and T=temperature. Solving for T in Equation 7 and substituting Equation 6 for P, equation T=(V/R) (v2/rA)(Equation 8) is obtained, wherein T is a function of radius r of tube 40. Assuming A is constant, taking the derivative of T and r, the following equation is obtained, To=[Ti 2+v2/R (ln(ro)−ln(ri))]1/2 (Equation 9), wherein To is the temperature of the gas stream at ro, and wherein Ti is the temperature of the gas stream at ri.
  • EXAMPLE 1
  • R=53.34 ft-lbf/lbm-° K
  • v=1129 ft/sec
  • ro=4 inches
  • ri=2 inches
  • Ti=75° F.
  • To=78.4° F.
  • An example of numerical values associated with kinetic energy heat pump 10 is shown in Example 1. For example, if gas molecules 21 enter nozzle 30 and ro of tube 40 is four (4) inches and ri of tube 40 is two (2) inches, and gas molecules 21 exit nozzle 30 at a velocity of approximately 1129 ft/sec, then Ti is 75° F., and, utilizing Equation 9, To of kinetic energy heat pump 10 is 78.4° F.
  • Additionally, as more clearly shown in FIG. 3, separating baffle 60 is selectively adjusted via rod 64 that positions separating baffle 60 by moving pivot 61 and top 62 of separating baffle 60 to vary the fraction of hot gas molecules 22 and cold gas molecules 23 entering hot opening 81 and cold opening 71, respectively. Separating baffle 60 selectively rotates about pivot 61, thereby increasing the amount of hot gas molecules 22 that exit hot output 83 and decreasing the amount of cold gas molecules 23 that exit cold output 73 or, alternatively, decreasing the amount of hot gas molecules 22 exiting hot output 83 and increasing the amount of cold gas molecules 23 exiting cold output 73, wherein bottom 63 of separating baffle 60 self adjusts to maintain an equilibrium pressure of gases through hot and cold channels 70, 80. It will be recognized by those skilled in the art that the quantity of hot gas molecules 22 and cold gas molecules 23 exiting cold outlet 73 and hot outlet 83 may be adjusted via any sort of means known in the art other than separating baffle 60 with pivot 61.
