The single port modulator apparatus comprises an inner valve with an inner and outer housing. The modulator has valve ports in the sides of the modulator. The inner valve rotates within the outer housing and the openings in the inner housing correspond to those ports in the outer valve. These openings connect with upstream or downstream tube sections in the bank of tubes and allow flow of fluid to be diverted. The actuator arm of the coil assembly rotates the inner valve thus changing the orientation of the outer and inner valve ports and so diverting fluid flow from various numbers of tubes depending upon how far the actuator is moved.Type: ApplicationFiled: May 15, 2002Publication date: November 20, 2003Inventor: Robert Peter Koenig

Patent number: 6626234Abstract: A coil modulator apparatus for use in connection with heat transfer coil assemblies found in commercial heating and air conditioning units is used to divert passage of water flow in certain sections of each tube in the coil assembly. The coil modulator apparatus comprises an inner valve, having valve ports in the sides of the valve, that rotates within an outer housing. Apertures in the outer housing connect with each tube in the bank of tubes so that there is an aperture in the outer housing that connects with both the downstream tube section and the upstream tube section of each tube. A portion of the water that collects in the modulator then flows back out of the modulator and into each of the downstream sections of every tube in the coil assembly. Another portion of the water in the modulator is diverted from the bank of tubes so that it flows out of the bypass tube of the modulator and directly back to the return feed of the coil assembly unit.Type: GrantFiled: June 1, 2001Date of Patent: September 30, 2003Inventor: Robert Peter Koenig

Publication number: 20030127213Abstract: A heat exchanging device includes a housing received in a container for allowing the fluid in the container to flow through the housing. A tube is extended through the housing. A driving device may pump the fluid in the container to flow through the housing and to have an increased heat exchange effect, within the housing, with the fluid in the tube, and may be driven by another driving device which may be actuated by the fluid flowing through the tube. A heater may be used to heat the fluid in the container and in the housing.Type: ApplicationFiled: January 10, 2002Publication date: July 10, 2003Inventors: Herman Lai, Bin Juen Huang

Patent number: 6453992Abstract: The present invention relates to a temperature controllable gas distributor which includes a cover having a first passage between its upper cover and lower cover, a second passage embedded along an edge portion of the upper cover, a first heater installed in the second passage, a support portion welded around the cover, and a distributing plate fixed at a lower portion of the support portion. The distributing plate includes a plurality of nozzles, and a third passage which is a passage of fluid is formed in the interior of the distributing plate 201. Second and third heaters are installed in the third passage. In the gas distribution apparatus according to the present invention, since it is possible to control the temperature of the cover and the distributing plate, namely, the entire portions contacting with gas, an abnormal reaction and liquefaction of a source gas can be prevented.Type: GrantFiled: May 3, 2000Date of Patent: September 24, 2002Assignee: Hyundai Electronics Industries Co., Ltd.Inventor: Chang-Jae Kim

Patent number: 6240742Abstract: A modular air-conditioning system is disclosed and consists of a power supply module, blower module(s), air-conditioning module(s), and an air-distribution module. The power module may be comprised of batteries, whereas the blower module provides ventilation through the air-conditioning system that extracts heat from the flow of fluid and directs the extracted heat to a heat exchanger. The heat exchanger is a closed-low pressure system consisting of a liquid filled with a water adsorbing material. The heat is extracted from boiling liquid in a lower chamber of the heat exchanger and transferred to an upper chamber of the heat exchanger by way of heat and mass transfer.Type: GrantFiled: December 1, 1999Date of Patent: June 5, 2001Assignee: The United States of America as represented by the Secretary of the NavyInventors: Jonathan W.
