Patent number: 9309870Abstract: The present disclosure provides a thermal actuator which comprises at least two containers containing a first fluid. The at least two containers define interior portions that are interconnected such that the interior portions of the containers are in fluidal communication with each other. The first fluid comprises a first liquid component and a second gaseous component. The thermal actuator is arranged such that a change in a temperature difference between one container and the or another container and within a predetermined range of temperature difference causes a quantity of a fluid contained in the thermal actuator to be transferred from the one container to the or another container such that a mass distribution of the thermal actuator is altered in response to the change in temperature difference so as to cause actuation.Type: GrantFiled: September 18, 2012Date of Patent: April 12, 2016Assignee: Nivaru B.V.Inventor: Nico van Ruth

Patent number: 6981383Abstract: A zoned HVAC system is provided with a series of dampers. A control for the dampers causes the dampers to each move between open and closed positions while monitoring a system condition. The system condition is selected to be one that should change as the damper moves between open and closed positions. If the system condition does not change as the control orders the damper to move between the open and closed positions, the particular damper is identified as a potentially faulty damper.Type: GrantFiled: May 7, 2004Date of Patent: January 3, 2006Assignee: Carrier CorporationInventors: Rajendra K.

Patent number: 4347972Abstract: An apparatus for producing hot water. A heat exchanger has a primary circuit which receives water from a hot water source and delivers the spent water back to the source. A secondary circuit through the heat exchanger receives unheated water and delivers it as hot tap water. A pump is connected in the line between the hot water source and the primary circuit of the heat exchanger, and a shunt bypass is connected in parallel with the series comprising the pump and the primary circuit of the heat exchanger. A sensing means such as a temperature sensing means senses the commencement of water flow through the secondary circuit and in response thereto operates the pump. Another temperature sensing means measures the temperature downstream from the primary circuit and in response thereto controls the distribution of fluid downstream from the primary circuit of the heat exchanger as between the shunt and the return line to the hot water source.Type: GrantFiled: February 12, 1980Date of Patent: September 7, 1982Assignee: AB CTCInventors: Bjorn Hillerstrom, Lennarth Fransson, Arne Thuvander

Patent number: 4305547Abstract: A water heater supplies hot water at a variable flow rate, depending on demand, and at a substantially constant, controlled temperature. It comprises a heat exchanger formed with an inlet and an outlet whereby water can be supplied to and withdrawn from the heat exchanger in accordance with demand and means for passing a second fluid such as steam through the heat exchanger coil to heat the water. A temperature gradient is thus established in the water in the direction of its flow through the heat exchanger. A sense tube forms a substantially homogeneous mixture of different portions of the water, these portions being drawn from sampling points spaced apart along the temperature gradient and in relative proportions depending on the flow rate of the water through the heat exchanger. The temperature of the water in the sense tube is detected, and control means responds to the sensed temperature for controlling the rate at which steam is supplied to heat the water.Type: GrantFiled: December 8, 1978Date of Patent: December 15, 1981Assignee: Aerco International, Inc.Inventor: Kenneth W.

Patent number: 4278069Abstract: A water heater comprises an elongated vessel having a heat exchanger that occupies a substantial portion at one end and leaves a minimum volume storage and blending zone at the other end of the vessel. Water is recirculated through the heat exchanger, preferably continuously, through a recirculation conduit that takes water through its inlet essentially solely from the outlet end of the heat exchange zone and returns it to the inlet end, the intake of the recirculation conduit being located at the lower end of the volume storage and immediately above an apertured partition extending across the interior of the vessel immediately above the heat exchanger. The temperature sensor of the control thermostat is received within a tunnel secured to the partition. The tunnel has two side outlet openings away from the aperture so that the thermostat is always subject to the hottest water just above the heat exchanger for fast and accurate control of the heating fluid on failure of the circulating pump.Type: GrantFiled: January 31, 1980Date of Patent: July 14, 1981Assignee: Harsco CorporationInventor: John A. Clark, Jr.

Patent number: 4098592Abstract: A process chromatograph including a column for separating fluid samples into their individual components, and a density-responsive detector connected to the column output to produce a pressure signal representing the concentration of the separated components. The column and associated elements are contained within a thermally-insulated housing the interior spaces of which are heated and maintained at a set-point temperature by a temperature regulating system. Heat energy is supplied by steam to one section of a two-section tubular heat-exchanger. A stream of air is caused to flow through the other section and into the housing interior, to transfer heat thereto. The rate of heat transfer is automatically controlled by a thermostatic control which continuously adjusts the flow of air through the heat exchanger so as to maintain the interior temperature at a desired set-point.Type: GrantFiled: November 24, 1976Date of Patent: July 4, 1978Assignee: The Foxboro CompanyInventors: Robert C. Prescott, Roy P. Lindquist
