Pump Or Thrower For Condensate Patents (Class 62/280)
  • Patent number: 11879663
    Abstract: An HVAC condensate evaporation system or aerobic dispersion system may transform the condensate that drains out of HVAC systems and/or septic systems into steam that is less likely to cause property damage. The system may be installed midstream in a condensate line and condensate that flows through the condensate line in normal operation may enter the chamber where it hits a solar-powered boiler that evaporates the condensate back into the atmosphere as steam. By converting the condensate into steam, property damage due to drainage out of the condensate line of an HVAC system may be minimized, or even eliminated. The system also may include a back-up capacitor or battery for low solar days. The system may further include wireless notification capability, including, but not limited to, Wi-Fi capability, to transmit notifications to the building owner or other interested parties of condensate issues as they may arise.

  • Patent number: 10619898
    Abstract: A water recirculation system operates in a primary mode for evaporatively cooling air. When the water recirculation mode malfunctions, the controller switches a secondary once-through mode. The system includes a sump for collecting water run-off from the evaporative pads, and a pump in fluid communication with the sump. The pump transfers moisture from the sump to the distribution arrangement located at the top of the evaporative pads during the recirculation mode. An automatically operated make-up water valve delivers water to a distribution arrangement on the evaporative pads. A moisture distribution arrangement distributes moisture to the evaporative pads and an automatically operated sump drain valve retains water in the sump when closed and freely drains water from the sump when open. A water level control communicates the sump water level to a control system. A monitoring mechanism detects whether the water-recirculation system has malfunctioned or is operating correctly.

  • Patent number: 6430955
    Abstract: Apparatus for distributing condensate over an outdoor heat exchanger of an air conditioner unit wherein the outdoor heat exchanger and an outdoor fan are enclosed within a housing. An orifice is located in the bottom of the housing adjacent to the fan and condensate produced in the unit is brought to the entrance of the orifice. The orifice is connected to a reservoir that directs condensate passing through the orifice to a point beneath the outdoor fan where the condensate can be picked by the fan and distributed over the heat exchanger surfaces. The size and shape of the orifice is matched to the pressure differential produced over the fan so that condensate is drawn rapidly into the housing and distributed by the fan over the outdoor heat exchanger.

  • Publication number: 20020092313
    Abstract: A system and method for a package terminal/split unit air conditioning unit which eliminates condensate leakage normally associated with air conditioning systems. The present invention includes a first section and a second section, where the first section connects to the second section by means of refrigeration piping, drain piping and electrical wiring and the first section includes a blower chamber and a condensing chamber. The air conditioning unit may operate with the two sections joined together or separated. During operation, the second section generates and collects condensate in a drain pan, the accumulated condensate flows, via drain piping, into a centrifugal blower within the first section. The centrifugal fan blower conveys the condensate into the condensing chamber. The heat within the condensing chamber causes the condensate to evaporate, and therefore eliminates leakage of condensate from the second section.

  • Patent number: 6349555
    Abstract: An orifice member for the condenser fan of an air conditioning unit which has a basepan and partition dividing the unit into an indoor section forward or the partition and an outdoor section behind the portion. The wall section has at least one through opening therein laterally spaced from the centerline of the orifice and in close proximity to the basepan. The opening communicates the region of the basepan on the high pressure side of the wall section with the low pressure side region of the basepan, which contains the sub-cooling coil. The opening is located and configured such that when the air conditioner is operating and condensate has collected in the basepan, condensate will be pumped through the opening from the high pressure side to the low pressure side and thereby cause turbulence in the condensate in the region of the basepan which contains the sub-cooling coil.

  • Patent number: 6298682
    Abstract: An orifice member for the condenser fan of an air conditioning unit. The air conditioning unit has a basepan, which supports a condenser coil and a condenser fan disposed forwardly of the condenser coil. The fan has a slinger ring formed at the outer periphery thereof. The slinger ring and the basepan are configured such that condensate water from the air conditioning unit will collect in the basepan underlying the bottom of the fan so that the slinger ring will be immersed in the collected water, pick up the water and direct it towards the condenser coil. The orifice member is provided with a fan orifice therein located forwardly of the fan so that the fan draws air through the orifice opening and directs it through the condenser coil. A diverter and a deflector cooperate to prevent water picked up by the slinger from being directed radially outwardly and through openings in the housing.

  • Patent number: 6085539
    Abstract: The base pan of a packaged terminal air conditioning system has a first condensate collecting surface under its evaporator coil and a second condensate collecting surface under its condenser coil. Fluid communication between the two surfaces is provided by a condensate flow channel, and the second condensate collecting surface is disposed at a lower vertical height than said first condensate collecting surface, such that the condensate which forms on the evaporator coil drops off and immediately flows to the second condensation collecting surface. A lifting wall is placed just upstream of a lower portion of the condenser fan and adjacent the second condensate collecting surface. The lifting wall, in cooperation with the fan creates an area of decreasing pressure above the second condensate collection surface so as to draw up the condensate into a radially inward portion of the fan where it is drawn into the fan and dispersed onto the condenser coil.

  • Patent number: 6067812
    Abstract: A rotating shroud is located on the suction side of the tips of a propeller fan and coacts with an inlet orifice to provide the physical separation between suction and discharge when the unit is in operation. The pressure differential across the fan tends to cause the condensate to move towards the suction side and into the path of the slinger (rotating shroud). The slinger then becomes wetted by the condensate, thereby picking up the condensate and slinging it into the region between the fan and the coil. The condensate is then evaporated upstream or within the coil, improving coil effectiveness.
