Patent number: 7147036Abstract: Two passages adjacent to each other via walls are formed spirally, and heat is exchanged between fluids passing through the passages via the walls. Upper and lower end faces of the spiral passages are covered with end plates, and the spiral passages and the end plates are sealed air-tightly. The end plates have a first passage inlet opening only to the first passage, a first passage outlet opening only to the first passage, a second passage inlet opening only to the second passage and a second passage outlet opening only to the second passage. Each of the inlets and outlets is open to every turn of the spiral passage. A first fluid entering the passage from the first passage inlet passes through the first passage for less than one turn only and is discharged from the first passage outlet. A second fluid entering the passage through the second passage inlet passes through the second passage for less than one turn only and is discharged from the second passage outlet.Type: GrantFiled: January 26, 2006Date of Patent: December 12, 2006Assignee: Kankyo Co., Ltd.Inventor: Hidetoshi Ike

Patent number: 7096929Abstract: A PCM system and method of shifting peak electrical load is provided with a PCM system including a heat exchanger, a storage tank coupled to the heat exchanger for storing PCM slurry, a pump coupled to the heat exchanger, an air conditioning unit coupled to the heat exchanger, and a heat rejection unit coupled to the storage tank. The PCM slurry is pumped from the storage tank to the heat exchanger. The energy at the heat exchanger is absorbed by the PCM slurry, and the PCM slurry is then returned to the storage tank. The energy absorbed by the PCM is rejected from the storage tank to a ground loop or by an air conditioning unit during a non-peak or less load demand period.Type: GrantFiled: March 27, 2003Date of Patent: August 29, 2006Assignee: Leading Technology Designs, Inc.Inventor: Randy Lee Clarksean

Patent number: 7085483Abstract: It is not possible to store heat of a domestic hot water supply level at a high density. If thermal storage temperature is T, variation in enthalpy in a chemical reaction is ?H, variation in entropy is ?S, and variation in free energy is ?G, a thermal storage material satisfying a relationship of T?S??G is used under a condition of ?H>0 so as to promote a reaction for putting the thermal storage material in a thermal storage reaction portion in an energy storing state by having supplemental energy added by an electrode portion when putting the thermal storage material in the energy storing state by decomposing or separating it.Type: GrantFiled: April 21, 2004Date of Patent: August 1, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tetsuo Terashima, Motohiro Suzuki

Patent number: 7080505Abstract: A vehicular atmosphere cleansing system utilizes a regenerative wheel having flow channels extending through the wheel coated with an adsorbant. An atmosphere stream passes through a first position dependent portion of the wheel where VOC's including HC's are adsorbed while a heated atmosphere stream passes through a second position dependent regenerative portion of the wheel whereat VOC's are desorbed. The adsorbant is activated carbon having particles of micropore size adhered to the substrate by a silicone binder producing high adsorption efficiencies while withstanding relatively high regenerative heat temperatures resulting from exhaust gas sensible heat. A hydrocarbon senses HC in the desorbed heated atmosphere stream to rotatively and sequentially index pie shaped, segmented portions of the wheel into the wheel's regenerative region while also functioning as the main component of an OBD device for the system.Type: GrantFiled: July 8, 2003Date of Patent: July 25, 2006Assignee: Engelhard CorporationInventors: Gerald S.

Patent number: 7077888Abstract: The invention relates to a device for separating dust from flue gases from combustion plants, especially solid fuel combustion plants, comprising at least one dust filter via which the flue gases are guided, and by means of which the dust from the flue gases can be filtered out as it passes through the dust filter. In order to produce a device which separates dust in a highly efficient manner and which can be operated in a highly reliable manner and be used to heat combustion air for the combustion plant, the at least one dust filter is embodied as a bulk material filter in whose bulk material heat from the flue gases can be collected when the bulk material is cross-flown by the flue gases and by means of whose bulk material heat collected from the flue gases when the combustion air of the combustion plant flows through the bulk material filter can be given off to said combustion air.Type: GrantFiled: January 9, 2004Date of Patent: July 18, 2006Assignee: Siemens AktiengesellschaftInventors: Harald Dichtl, Thomas Hagen, Roland Klaus, Jörg Lengert

Patent number: 7069979Abstract: A method, and a system for reducing the internal temperature of an electrical solenoid or motor device involves placing a heat absorbing phase change material (PCM) in intimate contact with the device to reduce the internal temperature of the device. The PCM material reduces the internal operational temperature of the device by undergoing an endothermic phase transition in an operating temperature range of the device. The PCM material transitions between a solid phase and a liquid phase in the internal operational temperature range of the device, or between a liquid phase and a gaseous phase in the internal operational temperature range of the device. The PCM material can be affixed externally to the device. For example, the PCM material is affixed in the form of externally placed pads to the device. The PCM material can also be affixed inside of the device.Type: GrantFiled: April 17, 2002Date of Patent: July 4, 2006Assignee: Lockheed Martin CorporationInventor: Lee A. Tobias
