Publication number: 20060254278Abstract: A heat regenerative engine uses water as both the working fluid and the lubricant. In operation, water is pumped from a collection pan and through a coil around a cylinder exhaust port, causing the water to be preheated by steam exhausted from the cylinder. The preheated water then enters a steam generator and is heated by a combustion chamber to produce high pressure super heated steam. Air is preheated in a heat exchanger and is then mixed with fuel from a fuel atomizer. An igniter burns the atomized fuel as the flames and heat are directed in a centrifuge within the combustion chamber. The speed and torque of the engine are controlled by a rocker and cam arrangement which opens a needle-type valve to inject high pressure super heated steam into a cylinder having a reciprocating piston therein. The injected steam expands in an explosive action on the top of the piston at high pressure forcing the piston down and drivingly rotating a linked crank cam and crankshaft.Type: ApplicationFiled: July 19, 2006Publication date: November 16, 2006Inventor: Harry Schoell

Publication number: 20060254291Abstract: A cooling system for cooling a plurality of heat producing systems includes a heat exchanger having a plurality of cooling zones, each of which has a respective inlet and outlet for facilitating flow of a respective temperature control fluid therethrough. Each of the respective temperature control fluids facilitates temperature control of a respective heat producing system. A plurality of fans cool the temperature control fluids flowing through the heat exchanger, and a fan or fans are disposed proximate each zone of the heat exchanger to provide air flow substantially independently from the air flow over the other cooling zones.Type: ApplicationFiled: May 10, 2005Publication date: November 16, 2006Applicant: EMP Advanced Development, LLCInventors: David Allen, Mark Bader, Robert Chalgren, Michael Lasecki, Michael Martin, Keith Brannstrom

Publication number: 20060254292Abstract: A cooling system for a heat producing system includes a heat exchanger in fluid communication with the heat producing system. The heat exchanger is configured to receive a temperature control fluid therethrough. A first fan is operable in a first rotational direction to move air through the heat exchanger in a first direction. A second fan is disposed radially adjacent to the first fan, and is operable in a second rotational direction opposite the first rotational direction to move air through the heat exchanger in the first direction. A control system, including at least one controller, is provided for controlling operation of the fans.Type: ApplicationFiled: May 10, 2005Publication date: November 16, 2006Applicant: EMP Advanced Development, LLCInventors: David Allen, Kim Aerts, Bradley Burch, Matthew Cardwell, Kurt Wasilewski

Publication number: 20060254293Abstract: A method of controlling a ceiling type air conditioner to rapidly generate uniform airflow in a room is disclosed. The method includes the steps of controlling the angle of the vanes to be a predetermined maximum angle to increase the airflow to a maximum airflow when initiating the ceiling type air conditioner, and decreasing the angle of the vanes from the maximum angle to a predetermined minimum angle step by step by a predetermined time interval to adjust the airflow. The airflow with the maximum rate can be supplied when initiating the air conditioner such that the chilled/heated airflow rapidly reaches the floor to improve the satisfaction of people in the indoor region. The rate of the airflow varies as time passes so that the uniform airflow can be rapidly supplied and the air conditioning efficiency can be improved.Type: ApplicationFiled: May 10, 2006Publication date: November 16, 2006Applicant: LG Electronics Inc.Inventors: Ju Lee, Ho Kim, Kwan Yum, Ho Choi

Publication number: 20060254294Abstract: An air conditioning apparatus has plural indoor units having: plural heat exchangers; and flow controllers respectively corresponding to the heat exchangers. In each of the indoor units, one heat exchanger is used as a condenser, and another heat exchanger is used as an evaporator, thereby causing the indoor unit to perform a temperature and humidity controlling operation. An indoor unit(s) which is not set to perform the temperature and humidity controlling operation may be caused to perform a heating operation or a cooling operation. Capacity controls on the condensers and the evaporators are performed by corresponding flow controllers. Gas refrigerants ejected from plural heat exchangers serving as evaporators are joined together, and then distributed to plural heat exchangers serving as condensers.Type: ApplicationFiled: October 30, 2002Publication date: November 16, 2006Applicant: MITSUBISHI DENKI KABUSHIK KAISHAInventors: Daisuke Shimamoto, Munehiro Yamanaka, Hidekazu Tani, Tomohiko Kasai, Masahiro Tsuda, Shuji Oura, Makoto Saitou
