The American Society of Heating, Refrigerating and Air-Conditioning Engineers ( ASHRAE ) officially concluded in 2005 that while completely isolated smoking rooms do eliminate the risk to nearby non-smoking areas, smoking bans are the only means of completely eliminating health risks associated with indoor exposure.

ASHRAE ( American Society of Heating, Refrigerating and Air Conditioning Engineers ), founded in 1894, is a building technology society with more than 50, 000 members worldwide.

Heating oil condenses at a lower temperature than the heavy ( C20 +) hydrocarbons such as petroleum jelly, bitumen, candle wax, and lubricating oil, which condense between.

Heating methods also diversified: modern producers use wood, oil, natural gas, propane, or steam to evaporate sap.

The University of New Brunswick has attempted to reduce its environmental impact through installing a natural gas burning microturbine at the Central Heating Plant that produces 100 kW of electricity for the university.

Heating is usually achieved by sending electricity through a resistor consisting of a hot incandescent filament, with the expanded gas expelled through a conventional nozzle.

A = Solution or suspension to be dried in, B = Atomization gas in, 1 = Drying gas in, 2 = Heating of drying gas, 3 = Spraying of solution or suspension, 4 = Drying chamber, 5 = Part between drying chamber and cyclone, 6 = Cyclone, 7 = Drying gas is taken away, 8 = Collection vessel of product, arrows mean that this is co-current lab-spraydryer

Heating is accomplished by the use of a forge fueled by propane, natural gas, coal, charcoal, coke or oil.

Heating and cooling water circulated through independent piping systems and passive solar input through the glass space frame panels covering most of the facility, and electrical power was supplied into Biosphere 2 from an onsite natural gas energy center through airtight penetrations.

Heating oil is widely used in parts of the United States and Canada where natural gas is not available and propane is priced higher.

Heating oil is the most common method of home heating in Northern Ireland due to the late development of a natural gas network.

* British Gas New Heating Limited-provides central heating and gas appliance installation and maintenance and low-carbon and energy efficient products and services

A proposal was made by Enwave ( the former Toronto District Heating Corporation ) and Constellation Energy to install advanced gas turbines and cogeneration inside the station and restore the station's control rooms, turbine hall and building exterior as a historical, filmmaking and education centre.

Heating the gas up to the initial temperature T < sub > i </ sub > increases the entropy by:

Heating the polymer above the effective glass transition temperature ( of the polymer / gas mixture ) then causes the plastic to foam, creating a very uniform structure of small bubbles.

The facility produces Liquified petroleum gas, Gasoline, Diesel and Heating oil for both the Swedish and foreign markets.

A sound trap is a special acoustical treatment of Heating Ventilating and Air-Conditioning ( HVAC ) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces.

Green and non-toxic building materials have been selected whenever possible to reduce outgassing and the use of non-renewable petroleum-based resources ; Heating and electrical systems were running well before occupancy so that as much outgassing of materials as possible happens BEFORE building occupants move in.

Heating a semiconductor can excite electrons into conduction states, but it is more practical to increase conductivity by adding impurities to the crystal.

Heating can also change the magnetization of steel.

Heating the elements is easy, as a strong electric current can raise the temperature of an element very quickly.

Heating, Ventilation and Air Conditioning ( HVAC ) solutions can include temperature and humidity control, and more commonly in Europe, fresh air, heating and natural cooling.

Heating due to resistance can cause extensive and deep burns.

Heating too slowly leads to entirely unpopped kernels: the tip of the kernel, where it attached to the cob, is not entirely moisture-proof, and when heated slowly, the steam can leak out of the tip fast enough to keep the pressure from rising sufficiently to break the hull and cause the pop.

Heating or contact of Hg ( CN )< sub > 2 </ sub > with acid or acid mist releases toxic mercury and cyanide vapors that can cause bronchitis with cough and phlegm and / or lung tissue irritation.

Heating elements of the tubular form are filled with a very fine powder that can absorb moisture if the element has not be used for some time.

* Cooked foods contain harmful toxins, which can cause chronic disease and other problems, Heating oils and fats can produce trace amounts of trans fats.

Heating and cooling a microreactor is also much quicker and operating temperatures can be as low as − 100 ° C.

Heating can be provided by several means, all of which are usually controlled by a thermostat:

Heating the water can be achieved through the use of concentrating solar power.

Heating the reaction mixture to 35 ° C releases carboryne, which can subsequently be trapped with suitable dienes:

# Heating and cooling can be reversed.

Heating packs can also be made by filling a container with a material that has a high specific heat capacity, which then gradually releases the heat over time.

Heating effects can be small-scale ( like the generation of gravity waves by convection ) or large-scale ( the formation of Rossby waves by the temperature contrasts between continents and oceans in the Northern hemisphere winter ).

Heating can be performed using sunlight combined with electrical heaters.

Heating white hypereutectic cast iron above causes the formation of austenite in crystals of primary cementite.

Heating borazine at 70 ° C expels hydrogen with formation of a borazinyl polymer or polyborazylene, in which the monomer units are coupled in a para fashion by new boron-nitrogen bonds.

Heating is by individual gas-fired, forced warm air systems.

Heating liquid in an open container results in rapidly increased evaporation, which concentrates the remaining flavor and ingredients – this is a critical component of both stewing and sauce making.

Heating an ideal mixture of two volatile substances A and B ( with A having the higher volatility, or lower boiling point ) in a batch distillation setup ( such as in an apparatus depicted in the opening figure ) until the mixture is boiling results in a vapor above the liquid which contains a mixture of A and B.

* Heating.

Heating or illuminating the object will release the captured electrons, producing a luminescence.

Heating is often achieved electrically, by passing an electric current ( supplied through an electrical cord or battery cables ) through a resistive heating element.

This efficiency is based on the Lower Heating Value of Hydrogen.

The Lower Heating Value of Hydrogen is total thermal energy released when hydrogen is combusted minus the latent heat of vaporisation of the water.

Heating and extruding basalt yields stone wool, an excellent thermal insulator.

The Interaction Heating Facility ( IHF ), with an available power of over 60-MW, is one of the highest-power arc jets available.

The Aerodynamic Heating Facility ( AHF ) has similar characteristics to the IHF arc heater, offering a wide range of operating conditions, samples sizes and extended test times.

Heating of the earth near the equator leads to large amounts of upward motion and convection along the monsoon trough or intertropical convergence zone.

As a result, a number of container-specific accessories have become available for a variety of applications, examples include ; Racking for archiving, Lining / Heating / Lighting / Powerpoints to create purpose-built secure offices, canteens and drying rooms, condensation control for furniture storage and ramps for storage of heavier objects.

* Heating the object above its Curie temperature, allowing it to cool in a magnetic field and hammering it as it cools.

* Heating a magnet past its Curie temperature ; the molecular motion destroys the alignment of the magnetic domains.

Heating, ventilating, and air conditioning is based on inventions and discoveries made by Nikolay Lvov, Michael Faraday, Willis Carrier, Reuben Trane, James Joule, William Rankine, Sadi Carnot, and many others.

In the United States, HVAC engineers generally are members of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers ( ASHRAE ), EPA Universal CFC certified, or locally engineer certified such as a Special to Chief Boilers License issued by the state or, in some jurisdictions, the city.
