Insulation r value
| Терминология инструкций к водонагревателям (Water Heater) |
A measurement of how well a water heater’s insulation will help prevent radiant heat loss through the tank. the r value of one inch (1”) of foam insulation is 8.33. a higher r value will help increase the overall energy factor.

Insulated flange, английский
A coupling used in metal pipes to interrupt the electrical transmission path that would otherwise exist.
Insulated gate pet, английский
Insulated overlap span, английский
An overlap span arranged with insulation between the two sections of overhead line equipment so that by the opening of an isolator or by the removal of connections, one section may be electrically separated from the other.
Insulated rail joint (irj), английский
A rail joint manufactured from components and assembled such that the joined rails are electrically insulated from each other.
Insulated wire, английский
Insulated-gate bipolar transistor, английский
Insulated-gate field-effect transistor, английский

Insulating board, английский
Insulating concrete, английский
Concrete having low thermal conductivity; used as thermal insulation.
Insulating fiberboard, английский
Fibrous insulating material (such as wood, cane, or other vegetable fibers) and binder, formed into a board. manufactured units vary widely in thickness, linear dimensions, density, thermal resistance, and mechanical strength.
Insulating flange set/spool, английский
Insulating form board, английский
Insulation board used as a permanent form for poured-in-place gypsum or lightweight-concrete roof decks.
Insulating glass, английский
- Window or door in which two panes of glass are used with a sealed air space between. also known as double glass.
- Two sheets of glass that are assembled and sealed around their edges as a single unit; the space between the glass sheets is dehydrated or filled with a gas. such a unit is effective in reducing the transfer of heat through it.
Insulating glass unit, английский
A panel of double glazing which is sealed around its periphery; provides increased resistance against the transmission of heat and sound. insulating glass unit 539 instantaneous-type water heater
Insulating glass unit. sealed hot-water system a hot-water heating system that has no expansion tank above the heating tank; i.e., the system is completely sealed., английский
Insulating glass., английский
Insulating glass. thermo on drawings, abbr. for thermostat., английский
Measurement, английский
- Set of operations having the object of determining a value of a quantity (1)
- Измерение. система мер.
- Измерение; замер
- The size, length, etc. of something which has been measured
- Измерение
- Обмер
- Оценка
- Измерение dust ~ измерение концентрации пыли
- Измерение. комплекс операций, имеющих целью определение значе-ния величины [32].
- The process of ascertaining the attributes, dimensions, extent, quantity, degree or capacity of some object of observation and representing these in the qualitative or quantitative terms of a data language. any empirical pursuit that places the observer outside his object of observation must consider measurement the fundamental process through which scientific constructs or models are linked to reality (->index, ->symptom). otherwise measurement is only one section in a circular process of computing a stable form. the traditional levels of measurement are nominal, ordinal, interval and ratio scales.
- The magnitude of the property of an object calibrated against one or more units of measure.
- Измерение. комплекс операций, имеющих целью определение значения величины [32].
Insulation, английский
- Material which offers extremely high resistance to the passage of current.
- Any material high in resistance to heat transmission that, when placed in the walls, ceiling, or floors of a structure, and will reduce the rate of heat flow.
- Any material that slows down the transfer of heat.
- Any material that reduces the speed of heat transfer
- Изоляция
- A material having high resistance to the flow of electric current. often called a dielectric.
- Изоляция; материал, используемый для изоляции холодильника (морозильника, термоконтейнера и т.п.) integrated disease surveillance (ids)
- Изоляция; материал, используемый для изоляции холодильника (морозильника, термоконтейнера и т.п.)
- Изоляция; изоляционный материал
- A material used to prevent the flow of heat into or out of a building. often consists of ‘batts’ placed in the ceilings and walls, but can also be metal foil or ‘loose fill’ materials, such as recycled paper fluff.
- A material used to prevent the flow of electricity. normally used on electrical wires to prevent electric shock. typical materials used include plastics such as pvc and polypropylene, as well as ceramics and minerals such as mica.

Drain valve, английский
- A plastic or brass valve located near the bottom of the water heater that allows the tank to be drained when the water heater needs to be replaced and also permits periodic partial draining by the homeowner to flush out sediments that may have accumulated
- Device designed to allow drainage of stored contents from a water heater.
- Small petcock or valve through which un¬wanted liquids that collect in a pipe system or mech¬anism are drained.
- Valve by which condensation is removed from the reservoirs of an air brake system,
Low-watt density and high-watt density heating elements, английский
A low-watt density electric heating element has a much larger surface area transferring heat to water in the tank. this spreads out the distribution of wattage. for example, each square inch of a 4500-watt low-watt density element is conducting less elect
