Title: Swimming pool, spa, or combination swimming pool and spa, heated with a heat pump with a heat exchanger

Description:
BACKGROUND 
   1. Technical Field 
   The present application relates to a swimming pool, spa, or combination swimming pool and spa, heated with a heat pump with a heat exchanger. 
   2. Background Information 
   Swimming and relaxing in a pool or spa are extremely popular pastimes in the United States. Swimming pools, both public and private, offer people relief from the heat while also offering an opportunity for social gatherings and fun for adults and children. Several types of swimming pools and spas exist, including in-ground pools, above-ground pools, wading pools for small children, spas, hot tubs, and whirlpools. Swimming pools and spas can be located outdoors, as in the back yard of a person&#39;s house or at a public community pool, or indoors, as in at a hotel pool or a private indoor pool. Further, swimming pools can be found in all different sizes, ranging from a small, above-ground pool that is only a few feet in depth, to a large, Olympic-sized pool, designed for competitive swimming or diving. Spas, hot tubs, and whirlpools can also be found in different sizes. 
   Many pools, especially indoor pools, are typically heated for the comfort of swimmers. Spas, hot tubs, and whirlpools are also heated for the comfort of users, as well as for therapeutic purposes for users. Since most indoor pools, including hotel pools and community pools, remain open to users year-round, and since most spas also remain open year-round, it is necessary for the heat exchanger to be able to constantly work with as little maintenance or repairs as possible. 
   Due to the necessity of swimming pool pumps to move or turn over the entire volume of pool water through the pool filter several times a day, any full flow heat exchanger must handle a high flow rate and thus high velocity of the water flowing through the heat exchanger. This high velocity poses several problems, as the high velocity could cause vibration of the coils which naturally have a spring resonant frequency and are prone to vibration. The vibration could be in the hundreds or even thousands of cycles per second, and over a short amount of time, the vibrations could rub a hole in the wall of the thin heat exchanger tube if the wall of the thin heat exchanger tube is allowed to contact either the adjacent tube wraps or the outer shell. 
   Due to the corrosive chlorine and pool sanitation chemicals used to treat swimming pools, including inorganic chlorinating agents such as calcium hypochlorite, lithium hypochlorite, sodium hypochlorite, and organic chlorinating agents such as trichloroisocyanuric acid, potassium dichloroisocyanurate, or sodium dichlorocyanurate as anhydrous or dihydrate forms, the tube material may comprise an alloy such as titanium or any high alloy stainless steels that can withstand these chemicals without fouling or corrosion, and to ensure continued service over time. The above alloys are typically costly materials, and thus to maximize heat transfer and to minimize expense, very thin wall tubing is commonly used in swimming pool and spa heat exchangers. Alloys such as these develop a hard film oxide coating, which helps to prevent the corrosion caused by chlorine and other pool sanitation chemicals. Because of this very abrasive coating, extra care must be taken to prevent tube damage caused by the wall tubing rubbing together if the wall tubing is allowed to touch and vibrate. 
   In addition, the tube wraps must be centered for optimum heat transfer uniform velocity. Therefore, a method and device for holding the tube wraps apart and centering the tube wraps would be beneficial to minimize damage and promote optimal operation. 
   Various methods of holding tube wraps apart and centering tube wraps have been used, including injecting silicone rubber between the tubes at intervals to freeze them in place, spreading the wraps apart and inserting rubber or plastic bumpers between the tubes, or placing long strips of material axially between the inner and outer coils during or after they are formed. All of these methods, however, have the disadvantage of requiring substantial care and time to assemble, and, in some cases, baking or curing time to set up the material before the heat exchanger coils can be used. Further, many of these methods are also costly to manufacture. 
   OBJECT OR OBJECTS 
   To provide a method and device for holding apart the tube wraps of a heat exchanger of a swimming pool or spa and to center the tube wraps of a heat exchanger of a swimming pool or spa. 
   SUMMARY 
   The coil key separator device shown in the detailed drawings is a simple, uniquely shaped device invented to solve the above problems with heat exchangers for swimming pools and spas. The coil key separator device offers the following advantages in a swimming pool or spa heat pump tube in shell heat exchanger: 
   1. The unique curved shape allows easy horizontal insertion between two tube wraps. When turned or twisted in a clockwise or counter clockwise direction, the coil key separator device spans at least one or several inner tube wraps, and also snap twists to lock itself and the outer tube the coil key separator device is inserted through into place. 
   2. The minimum profile of the coil key separator device also offers very little resistance to pool water flow in the normal axial direction. 
   3. The coil key separator device is quickly and easily inserted between tube wraps in a few seconds, and, with a quick 90 degree turn, the coil key separator device snaps into place, locking the tubes together. 
   4. The coil key separator device can be sized to exactly space the tubes as desired between each other and inside the outer shell. The coil key separator device can be any desired size, depending on the size of the heat exchanger in which it is used. 
   5. Three coil key separator devices placed radially 120 degrees apart will lock the tube position in all three axes, thus minimizing or essentially eliminating vibration and rubbing between the tube wraps. 
   6. The coil key separator device can be injection molded very inexpensively from softer or harder suitable plastic material. This material will withstand corrosion from pool or spa chemicals, as well as minimize friction between itself and the tubes or outer heat exchanger housing. 
   7. Three coil key separator devices inserted at the proper axial intervals along any length of tube coils will dampen essentially all vibration no matter how long the heat exchanger is. 
   8. The coil key separator device renders the heat exchanger coils immediately ready for the next assembly operation, and can be installed and used without delay. 
   The above-discussed embodiments of the present invention will be described further hereinbelow.

   DESCRIPTION OF EMBODIMENT OR EMBODIMENTS 
     FIGS. 1 ,  1 A,  10 ,  10 A,  11 , and  11 A each show possible embodiments of a pool and a heating system for a pool. The pool is connected to the heating system via a series of water pipes. Water flows from the pool to the heating system, where it is heated. Once the water is heated, it flows back to the pool. 
     FIG. 2  is schematic drawing of a typical pool heater with a shell in tube heat exchanger pool shown having a simplified single coil configuration. The pool heater comprises a coil  100  for carrying a heating agent, a housing  110  for containing water within the pool heater, and a water inlet  120  that is designed to permit water to flow into the pool heater. Once water is heated, it flows out through the water outlet  130 .  FIG. 3  shows another possible embodiment of a pool heating system. 
   According to one possible embodiment, as shown in  FIGS. 4 ,  4 A,  5 A,  5 B,  5 C,  6  and  7 , the heat exchanger  40  comprises an inner coil  30  and an outer coil  20 , as well as a surrounding wall  5 . There is a space  3  between the outer wall  5  and the outer coil  20 , and a space  1  between the outer coil  20  and the inner coil  30 . In order to heat the water of a pool or spa, the inner coil  30  and the outer coil  20  carry a heating agent that has been heated by a heater. Water from a pool or spa is pumped into the heat exchanger  40  so that it flows between the inner and outer coils  30  and  20  and in the spaces  1  and  3  within the outer wall  5 . The heating agent flowing through the inner coil  20  and the outer coil  30  transfer heat to the surrounding water in order to heat it. Heated water is then pumped out of the heat exchanger  40 . It should be noted that the separator device  10  can also be used in a single-coil embodiment of a heat exchanger, or any other embodiment of heat exchanger where the rubbing of two tubes together must be prevented. 
     FIG. 4  shows an overhead view of a heat exchanger  40  and the positioning of the separator devices  10  therein. In this embodiment, there are three separator devices  10  installed in the heat exchanger  40 . However, in other possible embodiments, more separator devices  10  or less separator devices  10  may possibly be used to separate the coils of the heat exchanger  40 .  FIG. 4  shows 3 separator devices  10  evenly spaced around the heat exchanger  40 , at approximately 120 degrees apart from each other. This even spacing dampens the vibration of the coils and substantially prevents the outer coil  20  from vibrating against each other, the inner coil  30  from vibrating against each other, the outer coil  20  from vibrating against the surrounding wall  5 , and substantially prevents the outer coil  20  from vibrating against the inner coil  30 . 
     FIG. 4A  shows a side view of two coil key separator devices installed between the coils of a heat exchanger for a swimming pool or spa. The inner portion  12  of the separator device  10  rests against the inner coil  30  of the heat exchanger  40 . The curved middle portion  14  rests between an upper rung  50  and a lower rung  60  of the outer coil  20 . In the locked position, the separator device  10  is positioned vertically, that is, the inner portion  12  and the outer portion  16  are disposed vertically when the separator device  10  is in the locked position. 
     FIG. 5  shows a perspective view of the separator device  10 . The separator device  10  comprises an inner portion  12 , a curved middle portion  14 , and an outer portion  16 . The outer portion  16  comprises rounded outer edges  18  that are easy to grip and twist the separator device  10  when it is being installed between the coils of a heat exchanger  40 . The inner portion  12  is substantially flat, so that it may rest against the side of an inner coil  30  of the heat exchanger  40 . The curved middle portion  14  is designed to rest between an upper and lower section of the outer coil  20  of the heat exchanger  40 . It should be noted that the separator device  10  may have larger or smaller dimensions depending upon the size and shape of the heat exchanger in which it is being used. 
     FIGS. 5A ,  5 B, and  5 C show a heat exchanger for a swimming pool or spa and coil key separator devices therefor, as well as possible measurements and dimensions therefor. It should be noted that the dimensions given in  FIGS. 5B and 5C  are only possible examples of one possible embodiment of a heat exchanger. Other possible embodiments of heat exchangers may be larger or smaller than the embodiment shown in  FIGS. 5B and 5C . The measurements and dimensions shown in  FIGS. 5B and 5C  are not meant to limit the present application to the embodiment shown in any way. 
     FIG. 6  shows the coil key separator device  10  installed between the coils of a heat exchanger  40  for a swimming pool or spa. The coil key separator device  10  is inserted between adjacent portions or sections of the outer coil  20 , such that the outer portion  16  and the inner portion  12  of the coil key  10  are positioned longitudinally with respect to the adjacent sections of the outer coil during insertion. Once the inner portion  12  comes into contact with the inner coil  30  of the heat exchanger  40 , the outer portion  16  of the separator device  10  is twisted clockwise or counterclockwise into a locked position, such that the curved middle portion  14  of the separator device  10  rests between the adjacent sections of the outer coil  20  of the heat exchanger  40 , and the outer portion  16  and the inner portion  12  of the separator device  10  are disposed in a vertical position. In the locked position, the separator device  10  substantially prevents the outer coil  20  from vibrating against each other, the inner coil  30  from vibrating against each other, the outer coil  20  from vibrating against the surrounding wall  5 , and it prevents the outer coil  20  from vibrating against the inner coil  30 . 
     FIG. 7  is a 3-D perspective view of several coil key separator devices installed between the coils of a heat exchanger for a swimming pool or spa. The coil key separator device  10  is inserted between an upper ring and a lower ring of the outer coil  20 , such that the outer portion  16  and the inner portion  12  are positioned longitudinally during insertion. Once the inner portion  12  comes into contact with the inner coil  30  of the heat exchanger  40 , the outer portion  16  of the separator device  10  is twisted clockwise or counterclockwise into a locked position, such that the curved middle portion  14  of the separator device  10  rests between an upper and lower rung of the outer coil  20  of the heat exchanger  40 , and the outer portion  16  and the inner portion  12  of the separator device  10  are disposed in a vertical position. In the locked position, the separator device  10  substantially prevents the outer coil  20  from vibrating against each other, the inner coil  30  from vibrating against each other, the outer coil  20  from vibrating against the surrounding wall  5 , and substantially prevents the outer coil  20  from vibrating against the inner coil  30 . 
   An example of a swimming pool or spa heating device, components of which may possibly be utilized or adapted for use in at least one possible embodiment, is the Heat Siphon swimming pool heat pump manufactured by United States Thermoamp Inc., located at 1223 Heat Siphon Lane, Latrobe, Pa. 15650. 
   The following is a description of a possible embodiment of a heater or heat exchanger for a pool or spa, components of which may possibly be utilized or adapted for use in at least one possible embodiment. The following description describes  FIGS. 8 and 9 . 
   The purpose of this electrical circuit is to detect a connection to a power relay  101 . A secondary function is to detect errors in the on-board control relay  102  that switches the voltage supply to the power relay  101 . 
   The entire circuit is powered by an AC signal which is supplied through terminals  103  and  104 . A metal oxide varistor  105  is used on the supply power to clip excessive voltages due to surges or lightning strikes. A thermal fuse is used on the line leg of the supply power to prevent a component failure from resulting in further damage. The fused line leg is multiplexed to the normally open contact of the on-board control relay  102  and to the diode bridge  106 . The neutral leg of the supply power is multiplexed to the neutral terminal of the power relay terminal  107 , the secondary side pin  108  of the opto-isolator  109 , and to pin  110  of the diode bridge  106 . 
   The diode bridge  106  rectifies the AC signal supplied on pins  110  and  111  into a DC signal with positive V RECTIFIED  on pin  112  and negative V SS  on pin  113 . The bypass capacitor  114  provides for a stable DC voltage. V SS  is supplied to one side of buffer resistor  115  while the other side of the resistor  115  is connected to the normally closed contact pin  116  of the on-board control relay  102 . The common contact  117  of the on-board control relay  102  is multiplexed to the line terminal of the power relay  118  and to one side of the voltage drop resistor  119 . The other side of the voltage drop resistor  119  is connected to pin  120  the primary side of the opto-isolator  109 . 
   Pin  121  of the opto-isolator  109  is tied to V SS  while pin  122  is pulled high to V CC  through a pull-up resistor  123 . Pin  122  of the opto-isolator  109  is also connected to the INPUT 1  pin  124  of the microcontroller  125 . The OUTPUT 1  pin  126  of the microcontroller  125  is connected to buffer resistor  127  which, in turn, is connected to the drive pin  128  of the darlington transistor  129 . Pin  130  of the darlington transistor  129  is tied to V SS , while pin  131  of the darlington transistor  129  is connected to pin  132  of the on-board control relay  102 . Pin  133  of the on-board control relay  102  is tied to V RELAY  which is the DC control voltage. Blocking diode  134  and bleed resistor  135  are connected in parallel with pins  132  and  133  of the on-board control relay  102  to provide additional protection for the on-board control relay  102 . 
   Two switch positions of the on-board control relay  102  are possible: common pin  117  connected to normally closed pin  117  and common pin  136  connected to normally open. The power relay  101  can either be attached to connectors  107  and  118  or disconnected from one or both of these connectors resulting in an open circuit. There are 4 possible combinations of these conditions. 
   For combination  1 , the Relay  102  Contacts are  117  to  116 , the Relay  101  Coil State is Connected, the PIN  118  Signal is AC (Neutral), the PIN  107  Signal is AC (Neutral), and the INPUT 1  PIN  124  is Waveform A; for combination  2 , the Relay  102  Contacts are  117  to  116 , the Relay  101  Coil State is Open, the PIN  118  Signal is See Waveform B, the PIN  107  Signal is AC (Neutral), and the INPUT 1  PIN  124  is Waveform B; for combination  3 , the Relay  102  Contacts are  117  to  136 , the Relay  101  Coil State is Connected, the PIN  118  Signal is AC (Line), the PIN  107  Signal is AC (Neutral), and the INPUT 1  PIN  124  is Waveform C; and for combination  4 , the Relay  102  Contacts are  117  to  136 , the Relay  101  Coil State is Open, the PIN  118  Signal is AC (Line), the PIN  107  Signal is AC (Neutral), and the INPUT 1  PIN  124  is Waveform C. 
   Combination  1 : In combination  1 , the on-board control relay  102  connects the common pin  117  to normally closed pin  116 . Power relay  102  coil is connected to pin  118  and pin  107 . The resistance of the control side of the power relay  101  is significantly less than the value of the buffer resistor  115  which forces the buffer resistor  115  to drop the majority of the voltage between V SS  and AC neutral. As a result, the voltage differential between pins  108  and  120  of opto-isolator  109  is not sufficient to energize the opto-isolator  109  circuit. The opto-isolator circuit is not energized, which results in the INPUT 1  pin  124  of the micro-controller  125  maintaining a constant state of V CC  (Waveform A). 
   Combination  2 : In combination  2 , the on-board control relay  102  connects the common  117  to normally closed pin  116 . Power relay  102  coil is an open circuit and therefore creating an open circuit between pin  118  and pin  107 . AC neutral is present on pin  107 . Due to the open circuit between  107  and  118 , there exists a voltage divider between V SS  and AC neutral across resistors  115  and  119 . The voltage differential between pin  107  and pin  117  results in a pulsed turn-on of the opto-isolator  109  and Waveform B on the INPUT 1  pin  124  of the micro-controller  125 . 
   Combinations  3  &amp;  4 : In combinations  3  and  4 , the on-board control relay  102  connects the common pin  117  to normally open pin  136 . AC neutral is present on connector  107  and AC line is present on connector  118 . Because the normally open pin  136  does not have a buffer resistor, the voltage on connector  118  is not affected by the presence of power relay  101 . The voltage differential between  118  and  107  results in a pulsed turn-on of the opto-isolator  109  and Waveform C on the INPUT 1  pin  124  of the micro-controller  125 . The waveform on INPUT 1  pin  124  is completely determined by the relay combination. The presence of Waveform A establishes that the power relay  101  is connected and that the on-board relay  102  is in the de-energized (normal) position. The presence of Waveform B establishes that the power relay  101  is not connected and that the on-board relay  102  is in the de-energized (normal) position. The presence of Waveform C establishes that the on-board relay  102  is in the energized position, but provides no information about the presence of the power relay  101 . 
   Two voltage states are possible on the OUTPUT 1  pin  126  of the microcontroller  125 : V SS  and V CC . These two states in combination with the 4 relay combinations listed above result in 8 cases as tabulated in Table 2.

The presence of waveform A indicates that the power relay  101  is properly connected. The presence of waveform B indicates that the power relay  101  is not connected. The presence of waveform C (combination 3 or 4), which indicates the energized position, directly indicates that the on-board control relay  102  has mal-functioned. Thus, before the microcontroller  125  energizes the OUTPUT 1  pin  126  to V CC , the power relay  101  can be detected. 
   The presence of V CC  on the OUTPUT 1  pin  126  of the micro-controller  125  should place the on-board control relay  102  in the energized position. The presence of waveforms A or B indicates that the on-board control relay  102  is in the de-energized position, and that the on-board control relay  102  is malfunctioning. The presence of waveform C (combination  3  or  4 ) indicates that the on-board control relay  102  is operating properly, but provides no information about the power relay  101 . 
   The resulting Logic is that if the microcontroller  125  has not energized the OUTPUT 1  pin  126 , waveform C indicates an on-board control relay  102  error. Waveform A indicates the presence of power relay  101  while Waveform B indicates the absence of power relay  101 . 
   If the microcontroller  125  has energized the OUTPUT 1  pin  126 , waveforms A and B indicate an on-board control relay  102  error.
