Temperature Control

	Temperature Control Temperature control is a process in which change of temperature of a space (and objects collectively there within), or of a substance, is measured or otherwise detected, and the passage of heat energy into or out of the space or substance is adjusted to achieve a desired temperature. Thermoregulation is the act of keeping the body at a static and regulated temperature that is suitable for the host despite the external temperature conditions.

picture info	Temperature Measuring And Controlling Module Nov Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Temperature is measurement, measured with a thermometer. It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), with the third being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible ...

picture info	Heat Exchanger A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, Petrochemical, petrochemical plants, Oil refinery, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant. Flow arrangement There are three primary classifications of heat exchangers accord ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Moving Bed Heat Exchanger Moving Bed Heat Exchangers (known as MBHEs) are widely used in industry, on applications involving heat recovery (providing a high volumetric transfer area) and filtering (avoiding common operational problems in fixed bed or ceramic filters like the pressure drop increase during operation). Construction The MBHE is a gravity driven indirect heat exchanger using fine grained bulk material. Media moves along heat transfer surfaces which can be tubes, plates or panels. MBHEs offer the advantages of little external equipment, a compact design, low maintenance cost and low construction costs. The Moving Bed Heat Exchanger can consist of several heat exchanger modules arranged one above the other. The product leaves the heat exchanger via the discharge bottom and a funnel. The funnel can be equipped with a collecting screw conveyor if necessary. This does not affect the moving bed. A roof-shaped protecting screen can be installed above the heat exchanger modules to keep out agglomerates a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Thermal Control System In spacecraft design, the function of the thermal control system (TCS) is to keep all the spacecraft's component systems within acceptable temperature ranges during all mission phases. It must cope with the external environment, which can vary in a wide range as the spacecraft is exposed to the extreme coldness found in the shadows of deep space or to the intense heat found in the unfiltered direct sunlight of outer space. A TCS must also moderate the internal heat generated by the operation of the spacecraft it serves. A TCS can eject heat passively through the simple and natural infrared radiation of the spacecraft itself, or actively through an externally mounted infrared radiation coil. Thermal control is essential to guarantee the optimal performance and success of the mission because if a component is subjected to temperatures which are too high or too low, it could be damaged or its performance could be severely affected. Thermal control is also necessary to keep specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
