Patent number: 6736194Abstract: A sorber heat exchanger is provided with a substrate material incorporating a sorbent for reacting with a polar gas refrigerant or hydrogen. A preferred sorbent is a metal salt capable of reacting with the polar gas refrigerant to form a complex compound. The sorbent incorporating substrate is loaded into the reactor space between the heat transfer surfaces. Incorporating the sorbent into the substrate reduces sorbent migration thereby improving performance and life expectancy of the heat exchanger.Type: GrantFiled: December 7, 2000Date of Patent: May 18, 2004Assignee: Rocky ResearchInventors: Uwe Rockenfeller, Lance D.

Patent number: 5901780Abstract: An auxiliary active heating and air conditioning system which uses a fuel fired heater as an energy source for both heating and air conditioning a passenger area of a motor vehicle. The system also utilizes a single heat exchanger to supply both heated and cooled air to the passenger area. The system includes a fuel fired heater for heating heat transfer fluid and a two bed sorber cooling system. The system being operable in a heating mode and a cooling mode. In the heating mode, the heated heat transfer fluid from the fuel fired heater is directed to heat exchanger in order to heat the passenger compartment. In the cooling mode, the heat transfer fluid from the heater is alternately directed to the two sorber beds such that one sorber bed is heated while the other bed cools. The alternate heating and cooling of the sorber beds in the cooling mode causes the sorber cooling system to operate and thereby deliver cooled heat transfer fluid to the heat exchanger in the passenger area.Type: GrantFiled: April 8, 1998Date of Patent: May 11, 1999Assignee: Rocky ResearchInventors: Terry A. Zeigler, Larry L. Peiffer, William G. Guo, Uwe Rockenfeller, Paul Sarkasian, Lance D. Kirol

Patent number: 5675982Abstract: A valve assembly includes a refrigerant inlet port and a refrigerant outlet port having a restricted opening, with the inlet port opening at least 2 times larger than the restricted outlet port opening. The valve includes components for opening and closing the inlet port in response to valve cavity pressure between the inlet and outlet ports.The larger inlet port relative to the restricted outlet port provides for rapid pressure buildup in the valve cavity when the inlet port is open which, in turn, causes rapid closing of the inlet port. The valve is capable of rapid cycling rates, highly effective for small refrigeration or cooling apparatus, as well as for controlling pressure in other applications requiring pressure regulation.Type: GrantFiled: April 26, 1996Date of Patent: October 14, 1997Assignee: Rocky ResearchInventors: Lance D.
