  • Patent number: 10717347
    Abstract: A vehicle air-conditioning system includes a cold-air circulation section in which indoor air of a vehicle is cooled via heat exchange with a refrigerant and is again supplied to a passenger compartment, a hot-air circulation section in which the indoor air is raised in temperature via heat exchange and is then again supplied to the passenger compartment, a purification circulation section in which the indoor air is introduced and purified and is then again supplied to the passenger compartment, and a refrigerant circulation section in which the refrigerant circulates to undergo heat exchange with the cold-air circulation section and the hot-air circulation section. The vehicle air-conditioning system separates an indoor air flow-path from an outdoor air flow-path to block outdoor air when performing air conditioning, and performs air conditioning of the passenger compartment using only the indoor air without entry of the outdoor air.

  • Publication number: 20150123294
    Abstract: An evaporative HVAC apparatus is disclosed. In at least one embodiment, the apparatus provides an at least one housing having an inner surface that defines a substantially tubular-shaped air passage extending therethrough. An absorbent wicking layer is formed immediately adjacent to at least a portion of the inner surface of the housing, and a thermal layer is formed immediately adjacent to an inner surface of the wicking layer. The housing also provides an at least one fluid inlet aperture through which a fluid line extends a distance into the housing so as to be in fluid communication with the wicking layer. Thus, a fluid is selectively delivered to the wicking layer through the fluid line which, in turn, permeates the thermal layer and evaporates into the air located immediately adjacent an exposed inner surface of the thermal layer, thereby affecting the temperature of the air moving through the air passage.

    Abstract: A flow distributor for a liquid descending in a vertically elongated mass transfer column, a mass transfer column employing the same, and a method of treating a fluid stream in the mass transfer column is provided. The flow distributor includes a central distribution member for passing liquid to a plurality of outwardly extending side arm members, which, in turn, feed the liquid into a plurality of distribution troughs located below the elongated side members. The distribution troughs, which may be oriented substantially perpendicularly or substantially parallel to the elongated side members, include a bed of packing material disposed therein. Use of such distributors in vapor-liquid or liquid-liquid columns results in more uniform horizontal distribution of the liquid across the diameter of the column.

  • Patent number: 8317901
    Abstract: The present disclosure generally relates to cyclonic separation or filtering of nanoparticles suspended in a gas. A plume of liquid droplets may be generated using an ultrasound or other generator. The gas may be mixed with the plume of liquid droplets, which may have received an electrostatic charge prior to mixing, to promote preferential adhesion of the nanoparticles to the liquid droplets. The gas with suspended nanoparticles and suspended liquid particles may flow through a cyclonic separator that spins rapidly, causing the cleaned gas to flow out of the filter while the liquid with adhered nanoparticles may be discharged, collected, and/or re-used in the plume generator. By causing nanoparticles to adhere to larger liquid particles, the filter may allow the filtering and collection of much smaller particles than current systems may filter under atmospheric pressure.
