- An elevator usually travels at lower speed. They are built to carry heavier loads and finished to withstand tougher working conditions
- The tower which holds the current record of world's fastest elevators with their cars traveling at 73.8 km/h (45.9 mph). The elevator, that was installed on July 7 2016 and was manufactured by Mitsubishi Electric.
- A device consisting of wire netting or the like used to stop or deflect sparks or embers thrown from an open fireplace or chimney.
- The quantity of heat absorbed or released by a substance during a change in phase at constant temperature and pressure.
- The transfer of heat by the circulatory motion of the heated parts of a liquid or gas owing to a variation in density and the action of gravity.
- Under PD1096, what is the minimum dimension of an accessible elevator?
- A small elevator for conveying food, dishes, or other materials between the floors of a building.
- A piston or spring device for absorbing the impact of a descending elevator car or counterweight at the extreme lower limit of travel.
- A boxlike structure on a roof providing access to a stairwell or an elevator shaft.
- A structure housing elevator machinery on the roof of a building.
- A wheel or disk with a grooved rim, used as a pulley for hoisting.
- A signaling apparatus in an elevator car or at a landing that displays a visual indication of floor landings.
- The toothed portion of the threshold plate at both ends of the escalator or moving sidewalk, designed to mesh with the grooved surface of the moving steps or tread way.
- A chair or platform mounted on a steel guide rail and driven by an electric motor, used for raising or lowering a person or goods along a stairway.
- The Horizontal section of railing at the upper and lower end of an escalator.
- Any of various forms of mass transit, such as moving sidewalks or automated driverless vehicles, used for shuttling people around airports or in congested urban areas.
- A device that automatically responds to changes in temperature and activates switches controlling such equipment as furnaces, refrigerators, and air conditioners.
- A rise in temperature occurring without the addition or removal of heat, as when excess water vapor in the air condenses and the latent heat of vaporization of the water vapor is converted to sensible heat in the air.
- Human comfort as determined by the ability of the body to dissipate the heat and moisture it produces by metabolic action.
- An instrument for measuring atmospheric humidity, consisting of two thermometers, the bulb of one being dry and the bulb of the other being kept moist and ventilated so that the cooling that results from evaporation makes it register a lower temperature than the dry one, with the difference between the readings being a measure of atmospheric humidity.
- A cast-iron stove resembling an open fireplace but having enclosed sides, back, top, and bottom and a front completely open or able to be closed with doors.
- An apparatus in which heat is produced, as for heating a house or producing steam.
- A pipe or duct fitting having several outlets for making multiple connections.
- A duct fitting forming a transition between two sections that varies in cross-sectional shape.
- A device having slats at different angles for deflecting or conditioning air from outlet in various directions.
- A heating device consisting of a series or coil of pipes through which hot water or steam passes.
- The cooling effect obtained when 1 ton of ice at 32°F (0°C) melts to water at the temperature in 24 hours, equivalent to 12,000 Btu/hr. (3.5kW).
- A liquid capable of vaporizing at a low temperature, such as ammonia, used in mechanical refrigeration.
- A pump or other machine for reducing the volume and increasing the pressure of a gas.
- A device for reducing a vapor or gas to liquid or solid form.
- A structure, usually on the roof of a building, in which heat is extracted from water that has been used for cooling.
- A removable plate for regulating the draft in the air outlet, air duct, or the throat of a fireplace
- A device for maintaining or increasing the amount of water vapor in the air of a room or building.
- An air-conditioning system in which either hot or chilled water is piped to fan-coil units in the served spaces, where air is circulated locally.
- An air-conditioning system unit in which central fans distribute conditioned air to the served spaces by means of ductwork.
- An air conditioning system that treats air at a central location and distributes the conditioned air to an entire building by means of fans and ductwork.
- A small faucet or valve for draining or releasing compression in pipes, radiators, and boilers.
- A valve for draining a pipe, radiator, or tank.
- A hot-water heating system in which a single pipe supplies hot water from a boiler to each radiator or convector in sequence.
- A special fitting used in a one-pipe system to induce the flow of water from a return branch into the supply main.
