Patent number: 5533669Abstract: A heat transfer apparatus is provided with a refrigerant heater, a single container disposed above the refrigerant heater, and the radiator spaced from the container. The container accommodates a partitioning plate for separating the inside of the container into a gas-liquid separating chamber and a liquid-receiving chamber, and a valve body for selectively opening and closing an opening defined in the partitioning plate is disposed within the container. The valve body is driven by an electrically operated driver mounted on the container. The heat transfer apparatus is also provided with a first group of pipes for communicating the refrigerant heater and the gas-liquid separating chamber, and with a second group of pipes for communicating the gas-liquid separating chamber, the radiator, and the liquid-receiving chamber.Type: GrantFiled: November 3, 1994Date of Patent: July 9, 1996Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Katsuzo Kokawa, Katsuhiko Yamamoto, Tatsuki Sakurabu, Satoshi Imabayashi, Muneo Tao

Patent number: 4880051Abstract: A piping apparatus for melting snow and ice, wherein a large number of heat radiation pipes are arranged below or above a surface from which snow or ice is to be melted and removed. One of the ends of each of the heat radiation pipes is communicated with an inlet side header arranged in a direction substantially orthogonal to the heat radiation pipes, and the other end of the pipes being communicated with an outlet side header arranged in a direction substantially orthogonal to the heat radiation pipes, thereby constituting a piping arrangement unit. The inlet side is communicated with a feed supply of a heating medium such as hot water so as to pass the supplied heating medium such as hot water through the heat radiation pipes. Heat retaining members having therein a heat accumulation material are disposed between the heat radiation pipes, whenever necessary.Type: GrantFiled: July 7, 1987Date of Patent: November 14, 1989Assignee: Kabushiki Kaisha Patine ShokaiInventor: Kazuo Ohashi

Patent number: 4844020Abstract: There is disclosed a heat recovery system for recovering the heat potential of a gaseous stream having a temperature of from 500.degree. to 2500.degree. F. utilizing a primary heat exchanger through which is passed a heat transfer salt mixture in indirect heat transfer relationship with the hot gaseous stream to recover the heat potential to use such primary heat transfer salt mixture in a plurality of serially arrayed heat exchangers as a heating medium for diverse fluids at descending temperature levels.Type: GrantFiled: March 15, 1988Date of Patent: July 4, 1989Assignee: American Hydrotherm Corp.Inventor: Alfred Bruhn

Patent number: 4662433Abstract: The instant invention is a major energy saver in the form of a blanket which allows personal heat control, particularly cooling. More specifically, the blanket is provided with internal ducts through which a stable foam is circulated as a cooling fluid in such a way that the inside of the blanket facing the person being cooled is maintained at a temperature slightly below body temperature, while the outside of the blanket is insulated to minimize heat exchange with the environment. Compared to the use of a liquid as the circulating cooling fluid, foam is very light and thus minimizes the weight of the blanket, but it has better heat transfer properties and heat capacity than a gas. Cooling of the recirculating cooling fluid is done separate from the blanket in a refrigeration unit connected to the blanket by a feed and return duct. The refrigeration unit can operate by means of a heat pump, or use a stored refrigerant such as ice, or employ a continuous coolant, such as tap water.Type: GrantFiled: August 29, 1984Date of Patent: May 5, 1987Inventors: Robert P. Cahn, Norman N. Li

Patent number: 4060194Abstract: A closed heating system in which a silicone fluid having a high specific heat is pumped through an element formed of tetrafluoroethylene. The element is provided with a plurality of small openings through which the fluid is forced. The fluid is heated and the heated fluid is forced to blow through one or more heat transfer units through which heat is transferred to the ambient atmosphere.Type: GrantFiled: March 8, 1976Date of Patent: November 29, 1977Inventor: George H. Lutz
