Definitions

  • the present disclosure relates generally to an apparatus and method for cooling an air conditioner system in order to boost the efficiency thereof.
  • some background on the operation of an air conditioner system may be helpful.
  • Willis Haviland Carrier developed the first modern air conditioning system in 1902. It was designed to solve a humidity problem at the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, N.Y. Paper stock at the plant would sometimes absorb moisture from the warm summer air, making it difficult to apply the layered inking techniques of the time. Carrier treated the air inside the building by blowing it across chilled pipes. The air cooled as it passed across the cold pipes, and since cool air cannot carry as much moisture as warm air, the process reduced the humidity in the plant and stabilized the moisture content of the paper. Reducing the humidity also had the side benefit of lowering the air temperature, and a new technology was born.
  • Air conditioners use to reduce the ambient air temperature in a room is based on a simple scientific principle. The rest is achieved with the application of a few clever mechanical techniques. Air conditioners use refrigeration to chill indoor air, taking advantage of a physical law— when a liquid converts to a gas (in a process called phase conversion), it absorbs heat. Air conditioners exploit this feature of phase conversion by forcing special chemical compounds to evaporate and condense over and over again in a closed system of coils. [0005] The compounds involved are refrigerants that have properties enabling them to change at relatively low temperatures. Air conditioners also contain fans that move warm interior air over these cold, refrigerant-filled coils. In fact, central air conditioners have a whole system of ducts designed to funnel air to and from these serpentine, air-chilling coils.
  • the maj or parts of an air conditioner manage refrigerant and move air in two directions: indoors and outside.
  • the parts consist of:
  • Evaporator - Receives the liquid refrigerant
  • Expansion valve regulates refrigerant flow into the evaporator;
  • Compressor A pump that pressurizes refrigerant.
  • the cold side of an air conditioner contains the evaporator and a fan that blows air over the chilled coils and into the room.
  • the hot side contains the compressor, condenser, and another fan to vent hot air coming off the compressed refrigerant to the outdoors.
  • the compressor typically is an electric pump that pressurizes the refrigerant gas as part of the process of turning it back into a liquid.
  • Btu British thermal units
  • a Btu is the amount of heat necessary to raise the temperature of 1 pound (0.45 kilograms) of water one degree Fahrenheit (0.56 degrees Celsius).
  • One Btu equals 1,055 joules.
  • heating and cooling terms one ton equals 12,000 Btu.
  • a typical window unit air conditioner might be rated at 10,000 Btu.
  • a typical 2,000-square-foot (185.8 square meters) house might have a 5-ton (60,000-Btu) air conditioning system, implying that a person might need perhaps 30 Btu per square foot.
  • the energy efficiency rating (EER) of an air conditioner is its Btu rating over its wattage. As an example, if a 10,000-Btu air conditioner consumes 1,200 watts, its EER is 8.3 (10,000 Btu/1,200 watts). Obviously, one would like the EER to be as high as possible, but normally a higher EER is accompanied by a higher price.
  • the present disclosure provides an alternative to the ever-increasing cost of electricity and the corresponding cost burden of using an air conditioner. As described in more detail below, the present disclosure reduces the amount of energy needed to condense the refrigerant on the hot side of the air conditioning system. Specifically, the present disclosure provides a novel system for spraying a mist of water on the air conditioner's condensing coils so that, as the water hits the coils and evaporates, it reduces the temperature of the coils. This reduced temperature assists in more rapidly reducing the temperature of the refrigerant inside the condenser and more rapidly enables the refrigerant to change from a gas to a liquid.

  • the solenoid valve 25 When the solenoid valve 25 is open, water flows through the control box 20 and into the filter 30.
  • the filter 30 softens the water flowing there-through so as to reduce mineral build-up in the second supply hose 40, the manifold 50, and on any surface in the air conditioner unit that gets wet as a result of using the apparatus. Locating the filter 30 on the downstream side of the control box 20 means that it is not under constant water pressure, as it would be if it were located on the upstream side of control box 20. This may extend the life of the filter 30.

  • a single manifold 50 can be used on one side of the air conditioner unit.
  • additional manifold units 50 can be connected together by uniting them at their inputs/outputs shown in FIGS. 4, 5A-5C (discussed below).

Depending on the configuration, this may add to the volume of water falling on the condenser inside the air conditioner unit.
  • a drain (not shown) is added to the valve between the filter 30 and the manifold 50. This drain valve would open when the misting system 5 is not on in order to drain water from manifold 50, the second supply hose 40, and the filter 30.
  • the time that the misting system 5 operates may also be important. For example, no water should be flowing if the air conditioner unit is not running. Control of the water supply is managed by programmable circuitry inside control box 20 (in order to open/close the solenoid valve 25) with the aid of one or more of the inputs/metrics shown in FIG. 5, as discussed below.

All three measurements are amplitude based. Because the apparatus typically is either full on or full off, it typically only cares about peak amplitudes of each metric.

  • the acoustics section uses the amplitude of the sound waves generated by the running compressor and fan as a turn-on verification.
  • a predetermined appropriate noise threshold is met (as sensed by the acoustic detector 515 and delivered to the CPU 505)
  • the CPU 505 will allow the misting system 5 to arm (i.e., capable of turning on the solenoid valve 25 if other parameters are met).
  • the compressor motor When the compressor motor turns on, it generates strong EMF around its core.
  • the CPU 505 is equipped with an antenna system (EMF detector 510 in FIG. 5) designed to pick up and measure these fields.

  • the acoustic detector 515 detects a sufficient level of "noise”
  • the EMF detector 510 detects a sufficient level of EMF. If all three of these metrics are met, the CPU 505 will issue a command to open the solenoid valve 25 and allow water to traverse the solenoid valve 25 and ultimately mist the air conditioner unit. If any one of these metrics are not met, the CPU 505 will not open the solenoid valve 25, thereby preventing any water from traversing the valve.
  • the CPU 505 can receive a wired or wireless input signal that further controls (or assists in the control of) the solenoid valve 25.
  • the received/input signal could be activated, thereby telling the CPU 505 to (1) either override the other inputs and open (or close) the solenoid valve 25 or (2) operate as another input for the controller to consider when deciding to open (or close) the solenoid valve 25.
