  • Patent number: 11466912
    Abstract: Embodiments of the present disclosure are directed toward purge units of vapor compression systems, and methods of control thereof, that selectively activate and deactivate the purge unit in response to one or more conditions to, for example, control refrigerant-to-air ratios while still minimizing the durations of the purge cycles. For example, in certain embodiments, these conditions may include conditions within the chiller condenser, time since last purge activation, time since last venting of non-condensables, and combinations thereof. By reducing an amount of time that the purge unit would be active without removing a substantial amount non-condensables from the vapor compression system, present embodiments reduce the power consumption of the purge unit, as well as the vapor compression system as a whole, while still being responsive to prevent or mitigate a loss of efficiency due to a substantial accumulation of non-condensables in the condenser of the vapor compression system.

The internal compartment of the boiler is separated into different zones by a plurality of primary baffle plates and secondary baffle plates. The hydrous feedstock compound is heated as it passes from one zone to another zone and ethanol inside the hydrous feedstock compound vaporizes. The ethanol rich vapor is channeled through a collector column and then collected for further processing. The temperature of the hydrous feedstock compound is slightly different from one zone to another zone because of ethanol concentration changes as the hydrous feedstock compound moves from one zone to another. At the last zone, where most of ethanol is removed, the remaining hydrous feedstock compound is removed from the boiler.

  • Publication number: 20090178790
    Abstract: An evaporator for use in a vapor compression system is disclosed. The evaporator may include an enclosure that covers a substantial portion of a tube bundle in the evaporator. The enclosure substantially prevents refrigerant vapor, generated as a result of the heat transfer with the tube bundle, from flowing laterally between tubes of the tube bundle. Various configurations of a distributor for distributing refrigerant to at least a portion of a tube bundle in the evaporator provides increased performance of the evaporator.

  • Patent number: 7468167
    Abstract: A method for quickly starting up a reactor and a reactor system therefor are provided. A shell-and-tube reactor in the system is adapted to circulate a heat medium having a solid point in the range of 50-250° C. to the outside of the reaction tubes and characterized by initiating temperature elevation of the reactor by introducing a gas of a temperature in the range of 100-400° C. to the reaction tubes' side and then circulating the heat medium in a heated state to the outside of the reaction tubes. By introducing a gas of an elevated temperature preparatorily to the reaction tubes, it is made possible to prevent the heat medium after circulation from being solidified again and enable the reactor to be quickly started up.

  • Patent number: 7219718
    Abstract: A tube bundle device useful in heat exchangers, condensers and other devices which has a number of tube support cages placed at extended locations along the length of the tubes. After the initial construction of the bundle in which the tubes are inserted into the support cages the tube bundle is stiffened by inserting sets of tube stakes between the tube support cages, preferably at the midpoint of the tube span between the cages. The tubes are supported by rods or bars in each tube lane at the tube support cage locations and the rods in each cage are rotated axially with respect to the rods in the next adjacent cage; in a similar manner, the stakes in each set are rotated axially with respect to the stakes in the next axially adjacent set.

  • Patent number: 7191824
    Abstract: A core for a charge air cooler comprises inner and outer concentric tubes providing an axially extending annular passageway for flow of a fluid, preferably a liquid coolant. A first inlet and a first outlet are provided at the ends of the axial annular passageway. Arranged on an outer surface of the outer tube is at least one circumferential fluid flow passageway for flow of a fluid, preferably air. Each circumferential flow passageway is provided with a corrugated strip fin comprising a plurality of rows of corrugations. The core is combined with an outer housing to form a heat exchanger. The housing is provided with an inlet and an outlet for the fluid flowing through the circumferential flow passageways. Other embodiments are disclosed in which the heat exchanger is adapted for use with three fluids and in which additional cooling capacity is provided by the provision of coolant passageways in the housing.

  • Patent number: 7117934
    Abstract: A heat exchange reactor including a housing, a plurality of tubes mounted in the housing and configured to carry a first fluid, and a baffle having a plurality of holes receiving the tubes. The baffle is configured to guide a second fluid provided within the housing to flow in a direction generally perpendicular to the tubes. The reactor includes various configurations for minimizing adverse effects of thermal expansion of the baffle and the tubes. The reactor is configured to minimize mechanical interference between the baffle and the tubes in both an operational state and a non-operational state, for example, by shaping the holes in the baffle to take into account thermal expansion. The reactor also includes a thermal insulator along a length of the tubes at a large temperature gradient zone within the reactor. The reactor further includes a heat transfer fin in contact with only one of the tubes.

  • Patent number: 6914955
    Abstract: A support plate for retaining tube array spacing within a heat exchanger tube and shell structure. The support plate having a plurality of individual tube receiving apertures formed therein. Each aperture has at least three inwardly protruding members and bights are formed therebetween when the tube associated therewith is lodged in place to establish secondary fluid flow through the support plate. The inwardly protruding members terminate in flat lands that restrain but do not all contact the outer surface of the respective tube. These flat lands minimize fretting wear and eliminate potential gouging of the outer wall of the tube. The plate wall forming each aperture has an hourglass configuration which, inter alia, reduces pressure drop, turbulence and local deposition of magnetite and other particulates on the support plates.
