With Means Preventing Or Handling Atmospheric Condensate Relative To Heat Absorber Patents (Class 62/272)
  • Publication number: 20030110790
    Abstract: A water removal device for refrigeration system comprises an electrode and a voltage source; the voltage source provides voltage for the electrode, which is located under the evaporator of the refrigeration system. Through the electric effect produced by the electrode, the condensed water condensed on the evaporator can be swiftly removed, a result that thoroughly takes advantage of the heat transfer function of the evaporator. In addition, there shall not be any electricity-discharging sparks between the electrode and the evaporator, thus assuring the normal operation of the refrigeration system.

  • Publication number: 20030046943
    Abstract: In a vehicle air conditioner, a refrigerant cycle system is constructed to switch a cooling refrigerant cycle where an interior heat exchanger is used as an evaporator, and a hot gas heater cycle where the interior heat exchanger is used as a radiator. Further, it is determined whether the interior heat exchanger has a quantity of retained water in a heating mode due to the hot gas heater cycle. When it is determined that the quantity of retained water is in the interior heat exchanger in the heating mode, operation of a compressor of the refrigerant cycle system is intermittently controlled so that temperature of air blown from the interior heat exchanger becomes lower than temperature of a vehicle windshield.

  • Publication number: 20020152762
    Abstract: An alternating electric field at an ice interface generates conductivity AC with a frequency greater than 1000 Hz in interfacial ice. Typically, a first electrode and a second electrode define an interelectrode space containing a stack of freezer packages. Each freezer package has an outer dielectric film and a continuous inner conductive layer coating the inside of the dielectric film. An AC power source provides a voltage of about 10 to 500 volts across the electrodes. The first and last freezer packages in the stack are proximate to the first and second electrodes, respectively. The AC voltage generates conductivity AC in the inner conductive layers. An alternating electric field between adjacent conductive layers generates conductivity current in the ice, resulting in Joule heat, which melts the ice.

  • Patent number: 6257008
    Abstract: In a cooling apparatus for cooling air, in order to improve heat absorption by a refrigerant, a metal having a high heat conductivity such as copper or aluminum is generally utilized as a constituent material of a heat exchanger. However, due to high heat conductivity, the temperature of a refrigerant becomes equal to the surface temperature of the heater exchanger, so that a space inside a refrigerator or a room is dried. Further, since the amount of latent heat of air decreases due to drying, cooling cannot be effected unless a temperature difference of 10° C. or more is produced between the inlet and outlet of the heat exchanger. An object of the present invention is to realize a cooling apparatus which does not decrease humidity and which produces a smaller temperature difference between an inlet and an outlet of a heat exchanger, i.e., reduces energy loss.

  • Patent number: 5894737
    Abstract: An improved housing for draining condensed water from the interior of a heating and air conditioning unit installed in a motor vehicle. The contoured bottom wall of the housing includes a raised portion surrounded by a series of sloped channels which lead to a collection basin having a drain. A fan or blower forces air through the housing inlet and past the heating and cooling elements. A portion of one of the sidewalls adjacent the air inlet interrupts the entering air to create a low pressure area. Condensed moisture is drawn along the sloped channels towards a collection basin located in the low pressure area. A drain is provided in the collection basin to remove the moisture from the housing.

  • Patent number: 5787721
    Abstract: A drain spout that is easy to remove for cleaning and for accessing components behind or proximal to the drain pan. Instead of directly connecting the drain hose to the drain pan outlet spout, the drain hose connects to a drain funnel attached to or formed as a part of the shelf supporting the drain pan. The drain pan itself sits on the shelf and the outlet spout of the drain pan fits within the shelf funnel without a positive connection. The drain pan can be lifted out without disengaging the drain hose.

  • Patent number: 5715696
    Abstract: An arrangement for reducing the humidity content of a gaseous medium, in particular air, has a cooling circuit. In order to increase its efficiency, an arrangement of this type is linked to a cooling system (10) known per se and has an evaporator (11) designed as a hollow body (16). The evaporator (11) has a pipe coil (17) through which a coolant, for example freon, can flow and a series of parallel ribs (18), preferably perpendicularly to the pipe coil (17), between which the gaseous medium is led in a first direction as a gas stream. The hollow body (16) is enclosed in an outer housing (12) forming an intermediate space (20) in which the gas stream is led in a second direction opposite to the first.

  • Patent number: 5699673
    Abstract: A compressed dry air supply system includes an air compressor which uses water for lubricating and cooling the movable parts thereof. Compressed air obtained from the compressor is sufficiently dehumidified by a refrigerator type dryer. The water produced due to the dehumidification of the compressed air is received in a water tank, and some of the water held in the water tank is recycled back to the compressor.

  • Patent number: 5669221
    Abstract: A portable, potable-water generator for producing high-purity liquid water by condensation of dew from ambient air. The generator employs filtration subsystems to remove particulates and aerosols from the incoming air. An enclosed heat absorber cools the filtered air to its dew point and collects droplets of condensate into a closed system. The collected dew is further continually treated in a bacteriostat loop to destroy adventitious living organisms and to filter out undesirable and dangerous contaminants. All the subsystems are failsafe-interlocked to disable the generator immediately and prevent delivery of water if any one of them stops functioning within predetermined safe limits.

  • Patent number: 5644925
    Abstract: A condensate trap for an air conditioning system includes a chamber having an upstream port coupled to the air conditioning system and a downstream port coupled to the external atmosphere, a sealing device disposed in the chamber, a lower seat member positioned in the chamber, and an upper seat member, disposed between the sealing device and upstream port. In response to a positive pressure at the upstream port, the sealing device contacts the lower seat member to prevent air from the air conditioning system from exiting to the external atmosphere. On the other hand, in response to a negative pressure at the upstream port, the sealing device contacts the upper seat member to form a seal which prevents the ingress of air from the external atmosphere into the air conditioning system. Moreover, in response to a predetermined amount of condensate accumulating in the chamber, the sealing device moves out of contact with the seat members to allow the fluid to drain from the downstream port of the chamber.

  • Patent number: 5517829
    Abstract: Water vapor in the atmosphere is condensed on a condenser surface which is cooled either by a standard refrigeration system or by a thermoelectric system. Condensate water is treated by filtration and by the addition of a disinfectant, and the treated water is stored in a holding tank. Auxiliary water from a local source is treated similarly in a parallel system and stored in a second holding tank. As it is pumped from holding tank to a dispensing tap, treated water passes through a second water treatment which filters pyrogens and other bacterial residue from the water, and also removes residual disinfectant.
