The disclosed embodiments relate to the design of a preconcentrator system for preconcentrating air samples. This preconcentrator system includes a plurality of preconcentrators that preconcentrate the air samples prior to chemical analysis, and a delivery structure comprising a manifold that selectively routes a sample airflow to the plurality of concentrators so that the plurality of preconcentrators receive a sample airflow concurrently or individually.

Heat exchanger assemblies and methods are provided for cooling the interior of an enclosure (e.g., electrical cabinets, computer server racks, chemical chambers, and animal cages). Heat is transferred via thermal conduction from a first plurality of surfaces positioned inside the enclosure to a second plurality of surfaces positioned outside the enclosure. The first and second plurality of surfaces remain in thermal contact with one another during use. Heat is dissipated from the second plurality of surfaces to the ambient air outside the isolated environment without the ambient outside air mixing together with the air inside the enclosure. This, in turn, inexpensively removes heat from the air inside the enclosure and prevents contaminants from entering the enclosure.

A system and a method for heating source fluid, comprising: a turbine-electric generator transport comprising: an inlet plenum and an exhaust collector; a turbine connected to the inlet plenum and the exhaust collector; and an electric-generator coupled to the turbine; an exhaust heat recovery transport comprising: a combustion air connection coupled to the inlet plenum; an exhaust air connection coupled to the exhaust collector; a heat transfer assembly coupled to the exhaust air connection; and a fluid system coupled to the heat transfer assembly; an inlet and exhaust transport comprising: an air inlet filter housing coupled to the combustion air connection; and an exhaust stack coupled to the exhaust air connection.

A heat pipe heat exchanger is used in combination with a damper assembly to selectively control an amount of heat exchange provided. A divider defines discrete heat pipe plenums and bypass plenums within a duct, and the heat pipe system is configured so that all of the coils of one portion of the heat pipe system are received in the heat pipe plenum(s), while the bypass plenum(s) are free of any coils. The damper assembly includes adjustable heat pipe dampers aligned with the heat pipe plenums and adjustable bypass dampers aligned with the bypass plenums. The damper assembly can include a single actuator that simultaneously opens the heat pipe dampers and closes the bypass dampers and simultaneously closes the heat pipe dampers and opens the bypass dampers.

The disclosure relates to a method for controlling a glass sheet heating furnace using information describing a glass load including a plurality of glass sheets. The method includes transporting the glass sheets toward a heating furnace, before thermal treatment, photographing the glass load by a camera to obtain a camera image, sending first information of the camera image to a computer, on the basis of which the computer determines a first value of a dimension of the glass load and selects a value of at least one adjustment parameter of the heating furnace on the basis of the first value before the glass load has been transferred into the heating furnace, and reading second information by a line scanner, which is sent to the computer, on the basis of which the computer determines a second value of the dimension of the glass load.

An architecture is presented for one or more climate systems controlled by one or more thermostat devices located in one or more dwellings associated with one or more users. Depending on the combination of the above factors, ecorank information is determined and presented. In some cases, the thermostats operate independently and settings are not propagated. In other cases, the thermostats operate dependently and settings are mirrored. One thermostat may be used to control another. Setting changes in at one thermostat may be presented at another thermostat. In some cases, the setting changes may require confirmation. In some instances, a hub device may be used to interconnect a thermostat device and server device.

A method for controlling a vehicle cooling system is provided. The system includes an engine, an EGR cooler, an oil cooler, a heater, a radiator, and a controller. The engine, the EGR cooler, the oil cooler, the heater, and the radiator are respectively connected through a coolant line and coolant circulates through the engine, the EGR cooler, the oil cooler, the heater, and the radiator by operation of a water pump. The controller receives the coolant from the engine and operates a control valve that is connected with the oil cooler, the heater, and the radiator. The method includes sensing driving conditions and operating the control valve when a warm mode is required to increase the temperature within the vehicle based on the sensed driving conditions. The control valve is operated based on first to third modes depending on a coolant temperature.
