Patent number: 9295181Abstract: A coolant-conditioning unit is provided which includes a facility coolant path, having a facility coolant flow control valve, and a system coolant path accommodating a system coolant, and having a bypass line with a system coolant bypass valve. A heat exchanger is coupled to the facility and system coolant paths to facilitate transfer of heat from the system coolant to facility coolant in the facility coolant path, and the bypass line is disposed in the system coolant path in parallel with the heat exchanger. A controller automatically controls a regulation position of the coolant bypass valve and a regulation position of the facility coolant flow control valve based on a temperature of the system coolant, and automatically adjusts the regulation position of the system coolant bypass valve to facilitate maintaining the facility coolant flow control valve at or above a specified, partially open, minimum regulation position.Type: GrantFiled: November 8, 2012Date of Patent: March 22, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Levi A.

Patent number: 9074799Abstract: Multiple cooling-storage containers are arranged in respective spaces formed between neighboring refrigerant tubes. The cooling-storage container is made of a pair of outer envelope portions, each forming a side wall. Multiple convex portions and concave portions are formed in the side walls so that air passages are formed between refrigerant tubes and the concave portions. A sectional area of the air passage formed in a lower portion of the cooling-storage container below a predetermined height is made larger than that of the air passage formed in an upper portion of the cooling-storage container above the predetermined height.Type: GrantFiled: May 2, 2012Date of Patent: July 7, 2015Assignee: DENSO CORPORATIONInventors: Jun Abei, Tomohiko Nakamura, Hirofumi Futamata, Toshiya Nagasawa

Patent number: 9044371Abstract: The present invention is a scalable and portable human remains cold storage system having a chiller unit for providing a chilled fluid to a remains chilling bag. A flow divider manifold fluidly communicates with the chiller unit for dispersing the chilled fluid to the remains chilling bag and then channeling warmed fluid back to the chiller unit for re-chilling through a series of supply lines. The fluid flows through a continuous cycle to maintain a desired temperature within the remains chilling bag.Type: GrantFiled: April 1, 2008Date of Patent: June 2, 2015Assignee: Trailerlogic, LLCInventor: Michael P.

Publication number: 20150128635Abstract: A refrigeration apparatus uses R32 as a refrigerant, and includes a compressor, a condenser, an expansion mechanism, an evaporator and an accumulator. The accumulator is disposed in the suction flow path supplying refrigerant to the compressor. The accumulator has a casing that forms an inside space to separate the refrigerant into gas refrigerant and liquid refrigerant and accumulating surplus refrigerant, an inlet pipe feeding the refrigerant that has evaporated in the evaporator into the inside space, and an outlet pipe channeling the separated gas refrigerant to the compressor. A distal end opening in the inlet pipe of the accumulator is located in a height position separated by a dimension from a bottom of the inside space. The dimension is 0 to 0.3 times a height dimension of the inside space.Type: ApplicationFiled: May 8, 2013Publication date: May 14, 2015Inventors: Satoshi Kawano, Shinya Matsuoka

Publication number: 20150121945Abstract: A cylindrical hole is formed between peripheral belt portions of two container constituent plates of a thermal storage material container of an evaporator with a cool storage function. A cylindrical portion of a thermal storage material charging member having a thermal storage material charging passage is disposed in the cylindrical hole and brazed to the two container constituent plates. That portion of the thermal storage material charging member which protrudes from the cylindrical hole includes a crushed portion and a cylindrical uncrushed portion. The crushed portion seals the thermal storage material passage. The cylindrical portion of the thermal storage material charging member is smaller in outside diameter than the uncrushed portion, and the cylindrical portion and the uncrushed portion have the same inside diameter. The cylindrical portion has an inward protrusion protruding into a thermal storage material containing space, and the inward protrusion has a radially expanding engagement portion.Type: ApplicationFiled: October 29, 2014Publication date: May 7, 2015Applicant: KEIHIN THERMAL TECHNOLOGY CORPORATIONInventors: Osamu KAMOSHIDA, Mitsuru NOBUSUE

Publication number: 20150089971Abstract: A refrigerant circuit performs a cool storage operation in which a thermal storage medium is circulated such that a refrigerant having been condensed in an air heat exchanger and passed through an auxiliary heat exchanger is evaporated in the thermal storage heat exchanger. In a thermal storage circuit during the cool storage operation of the refrigerant circuit, the thermal storage medium is circulated such that the thermal storage medium having flowed out from an outlet of a thermal storage tank sequentially passes through the auxiliary heat exchanger, a retention portion, and the thermal storage heat exchanger and flows into an inlet of the thermal storage tank. The retention portion retains crystals contained in the thermal storage medium.Type: ApplicationFiled: September 29, 2014Publication date: April 2, 2015Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Shuji FURUI, Kouichi YASUO, Kebi CHEN

Patent number: 8978391Abstract: A method for generating a thermal flow from a thermal module comprising at least two magnetocaloric elements connected, two-by-two, through which a heat transfer fluid flows and is exposed to a magnetic field. The circulation exposes alternating elements of the magnetocaloric elements to an opposite variation in the magnetic field, and causes the transfer fluid to circulate simultaneously and in opposite directions in such a manner that the fluid flowing out of one of the magnetocaloric elements, at the end of a heating phase, is circulated, during the following phase, in the following magnetocaloric elements exposed to heating, while the fluid flowing out of one of the magnetocaloric elements, at the end of a cooling phase, is circulated in the following element exposed to cooling, and conversely. The heat transfer fluid is stored an intermediate receiving area. This invention also relates to a thermal generator implementing the method.Type: GrantFiled: April 27, 2011Date of Patent: March 17, 2015Assignee: Cooltech Applications SASInventors: Christian Muller, Jean-Claude Heitzler
