heating temperature
51District heating substation — A district heating substation in a residential neighborhood with a thermal capacity of 300 kW. Two components of the heat meter are visible: the metering electronics unit on the right (white/blue box), and the ultrasonic flow meter in the center… …
52Joule heating — Joule heating, also known as ohmic heating and resistive heating, is the process by which the passage of an electric current through a conductor releases heat. It was first studied by James Prescott Joule in 1841. Joule immersed a length of wire… …
53Potential temperature — The potential temperature of a parcel of fluid at pressure P is the temperature that the parcel would acquire if adiabatically brought to a standard reference pressure P {0}, usually 1000 millibars. The potential temperature is denoted heta and,… …
54Curie temperature — In physics and materials science, the Curie temperature (Tc), or Curie point, is the temperature at which a ferromagnetic or a ferrimagnetic material becomes paramagnetic on heating; the effect is reversible. A magnet will lose its magnetism if… …
55Negative temperature coefficient — A negative temperature coefficient (NTC) occurs when the thermal conductivity of a material rises with increasing temperature, typically in a defined temperature range. For most materials, the thermal conductivity will decrease with increasing… …
56Operative temperature — (to) is defined as a uniform temperature of a radiantly black enclosure in which an occupant would exchange the same amount of heat by radiation plus convection as in the actual nonuniform environment.[1] Some references also use the terms… …
57induction heating — a method of heating a conducting material, as metal in a furnace, by using electromagnetic induction to establish a current in the material. [1915 20] * * * Method of raising the temperature of an electrically conductive material by subjecting it …
58Central heating — unit A central heating system provides warmth to the whole interior of a building (or portion of a building) from one point to multiple rooms. When combined with other systems in order to control the building climate, the whole system may be a… …
59Space heating — is the heating of a space, usually enclosed, such as a house or room. A space heater keeps the air and surroundings at a comfortable temperature for people or animals, or even plants in a greenhouse. Space heating generally warms a small space,… …
60Self-heating can — A self heating can is an enhancement of the common food can. Self heating cans have dual chambers, one surrounding the other. The inner chamber holds the food or drink, and the outer chamber houses chemicals that undergo an exothermic reaction… …
