A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [1] [2] [failed verification] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters.
Specifically, the heat pump transfers thermal energy using a heat pump and refrigeration cycle, cooling the cool space and warming the warm space. [1] In winter a heat pump can move heat from the cool outdoors to warm a house; the pump may also be designed to move heat from the house to the warmer outdoors in summer.
Electric fan heater. A fan heater, also called a blow heater, is a heater that works by using a fan to pass air over a heat source (e.g. a heating element). [1] This heats up the air, which then leaves the heater, warming up the surrounding room. They can heat an enclosed space such as a room faster than a heater without a fan, [2] but like any ...
The condenser is the hot side of an air conditioner or heat pump. Condensers are heat exchangers, and can transfer heat to air or to an intermediate fluid (such as water or an aqueous solution of ethylene glycol) to carry heat to a distant sink, such as ground (earth sink), a body of water, or air (as with cooling towers). constant air volume
Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...
UVW mapping, a mathematical technique for coordinate mapping; University of Virginia's College at Wise, a public liberal arts college in Wise, Virginia; Unloaded Vehicle Weight, the weight of a vehicle as manufactured at the factory
Snow and blowing snow advisory WSW – Sustained winds of 25 to 35 miles per hour (40 to 56 km/h) are expected to be accompanied by falling and blowing snow, occasionally reducing visibilities to 1 ⁄ 4 mile (0.40 km) or less for at least three hours. Discontinued beginning with the 2008-2009 winter storm season and replaced by the winter ...
Electrical cord for powering a block heater. A block heater is used in cold climates to warm an engine prior to starting. They are mostly used for car engines; however, they have also been used in aircraft engines. The most common design of block heater is an electrical heating element embedded in the engine block.
