Convection is the transfer of heat between objects that are not touching each other. Instead, the heat is transferred by means of a fluid, such as water or air. The fluid is heated and the heat is transferred within it to the other object. Movement in the fluid is called a convective current.

Convection
When a fluid (liquid or gas) is next to a solid surface of a different temperature, heat will be transferred.

~ - A method of transferring heat by the actual movement of heated molecules, usually by a freestanding unit such as a furnace.
COOLING TOWER - A large device mounted on roofs, consisting of many baffles over which water is pumped in order to reduce its temperature.

~- Currents created by heating air, which then rises and pulls cooler air behind it. Also see radiation.

What is Convection?
A convection oven cooks faster than conventional. It works basically the same as a conventional oven, but uses a fan to circulate the heat evenly. This results in more even and faster cooking on all racks.

Natural Convection - A heat transfer process involving motion in a fluid (such as air) caused by difference in density of the fluid and the action of gravity. This is an important part of heat transfer from the glass surface to room air.

Gravity Convection - The natural movement of heat that occurs when a warm fluid rises and a cool fluid sinks under the influence of gravity.
Heat Capacity - A property of a material denoting its ability to absorb heat.

~ is energy transport by the combined action of heat conduction, energy storage, and mixing action.

~ ovens are just an oven with a fan inside, it's that simple. But the fan significantly improves the function of the oven. The circulation of the air inside the oven results in faster, more even baking.

~: heat transfer through either the natural or forced movement of air.

COUNTERSINK: to sink a nail or screw below the surface.

~--A process of heat transfer whereby heat energy is transferred from one location to another -- created by the motion of air resulting from a difference in temperature and the action of gravity.

~: Refers to the transfer of heat by moving fluid (liquids and gases).
Coping: A cap or top course of a masonry wall to protect lower areas from water penetration.

~
A transfer of heat through a liquid or gas when that medium hits against a solid surface.

~-The transfer of heat by the motion of the heated matter.
COPPER GAS CONNECTOR-Sulfur in natural gas reacts with copper and can cause the connector to deteriorate
and leak. We recommend that copper tubing be removed and be replaced with an approved gas supply connector.

~ - Transferring heat by moving air, or transferring heat by means of upward motion of particles of liquid or gas heat from beneath.
CONVENTIONAL GAS - Natural gas occurring in nature, as opposed to synthetic gas.

With convection cooking capabilities, this microwave oven offers more cooking options, better results, and less cook time than conventional microwaves.

~:
The flow of heat through a circulating gas or liquid, such as the air in a room or the air or gas between window panes.

~ The transfer of heat by air flow. Radiation The transfer of heat directly from one surface to another (whithout the intermediate air acting as a transfer mechanism).
Insulation Terminology ...

Conduction The transfer of heat through a solid material.
Convection The transfer of heat by air flow.
Radiation The transfer of heat directly from one surface to another (whithout the intermediate air acting as a transfer mechanism).

Radiator An exposed fixture that heats with a combination of radiation and convection; e.g. the common, cast-iron radiator; as distinguished from convectors, finned heating elements that are concealed in walls or cabinets, e.g., baseboard heating.

Solar heat is transferred from where it is collected and stored to different areas of the house by conduction, ~, and radiation. In some homes, small fans and blowers help distribute heat.

This process of heat transfer is called ~. Warm air, which is lighter, rises and, as it cools, falls, creating a ~ current of air.

~
Process of heat carried from one point to another by movement of a liquid or a gas (i.e., air). Natural ~ is caused by expansion of the liquid or gas when heated. Expansion reduces the density of the medium, causing it to rise above the cooler, more dense portions of the medium.

But the principle of ~ is also at work in a fireplace, and this is one reason why they can be so inefficient. The major portion of the heat that a fire creates is in the form of hot gas. ~ sends this gas up the chimney, where it is wasted.

Some older systems have no circulator and use ~ (the tendency of heated water to rise) to circulate the water in a building. These are called ~ hot water or gravity hot water systems. ~ hot water heating is inefficient and considered obsolete.

Rather than directing a high pressure water jet at an area of the body, air baths create ~ currents throughout the bath and massage the whole body. In addition the volume of air can be reduced to a constant stream of massaging bubbles that gently caress muscles helping them to relax.

Coffee beans can also be roasted in gas and ~ ovens. Since I own an electric non-convected air oven, I have not tried this method. Some, but not all, electric hot corn poppers will do a great job of roasting coffee beans.

2 A speedy second oven, the 1,700-watt Waring Pro ~ oven sits on the counter and makes quick work of baking, roasting, broiling, and rotisserie cooking ($399; waringproducts.com).

I invested in the microwave ~ and the ~ steam ovens after some considerable research, I am disappointed in their performance. The micro ~ cooks unevenly and is difficult to clean.

With a gravity furnace, ~ currents (caused by the natural tendency of hot air to rise) carry heated air through the system from a furnace located on or below the main floor. Gravity systems do not have blowers, tend to have very large air ducts, and can only deliver warmed air.

The concept of air movement, called natural ~, is an integral part of all successful solar heating installations. If a solar heating system works with natural ~, hot air rising and cold air falling, then the result in comfort level can exceed expectations.

The Viking Professional Series ~ microwave is finished in Iridescent Blue to match the St. Charles cabinetry, which " like Viking appliances " comes in 23 powder-coated colors as well as the original stainless steel. The Venuto Bar-Prep faucet has a pull-down sprayer with two settings.

There are multiple cooking functions including bake with ~, defrost, broil, toast, keep warm and pizza. The 2-hour time will automatically shut the toaster oven off in case you forget to.

What I like in those bedrooms is that they are far from being ~al, they speak real about a free life style, where casualty and intruders are well digested, where a sleeping room is not a place to show how rich or sophisticated you are, ...

Heat Loss
The transfer of heat from inside to outside by means of conduction, ~, and radiation through all surfaces of a house.

The original hot water systems operated by gravity flow, with the heated water rising by ~ through the distribution system. This type system also uses a manual feed valve and open expansion tank, usually installed in the attic or an upper closet.

In thermo siphon circulation systems, the water is circulated by natural ~ resulting from the difference in water density due to temperature difference of the water in different parts of the system.

2. An undercounter speed oven combines a microwave with a ~-mode oven and is integral for a busy lifestyle.
3. Tucked right alongside the range and wall, a small section of counter is a handy spot for storing and displaying oils and spices in pretty bottles and jars.

Furnace
A heating system that uses the principle of thermal ~. When air is heated, it rises and as the air cools it settles. Ducts are installed to carry the hot air from the top of the furnace to the rooms. Other ducts, called cold air returns, return the cooler air back to the furnace.

CONVECTOR: A heat-transfer surface that uses ~ currents to transfer heat.
COPING: Metal cap or masonry top course of a wall.
CORBEL: Projection of masonry from the face of a wall; a stepped coursing bracket to support weight above.

Even a small vacuum is effective in reducing conduction and ~ heat losses, so the gap between the two panes can be reduced to just 0.2 mm, giving an overall unit thickness of just over 6 mm.

Many of your energy dollars can be lost from the top of your water heater. There are continuous ~ currents in the pipes right above the water heater. These water currents can draw a lot of heat out of your water heater. Adding some foam pipe insulation in these areas can help a lot.

CHIMNEY: vertical tube for venting flue gases by natural ~.
CHIMNEY FIRE: burning of creosote and other deposits within a chimney.
CHORDS: framing members that make up the two sides of the roof and the base of a triangular truss.

The rest of the appliances fit just right. We got two double ~ ovens with built-in fans for more even baking and an extra element for nice browning.

The feel of an old-fashioned range cooker has been achieved by creating a tiled alcove, which accomodates a very modern ~ oven and induction hob.

The U-3036RR side-by-side under-counter refrigerator is intended to maximize food preservation with four temperature zone settings. It also boasts a digitally controlled, dual zone ~ cooling system and an integrated OLED display with user interface ergonomically located on top of its door.

Radiation- Energy transmitted from a heat source to the air around it. Radiators actually depend more on ~ than radiation.

Since windows lose and gain heat by conduction, ~, radiation and air leakage, it is essential to choose the right material. Connections where the frame joins together must be tightly sealed to keep out water and air.

When choosing a stove or cooktop for your kitchen, you are usually presented with two main options: gas or electric. Gas ranges are generally considered better for cooking than electric. If you do go electric, consider a model with a ~ oven, which can save both time and energy when cooking.

~,Steam, moisture. If you put your hand above a boiling pot, you will feel heat in the form of steam. This is convective heat transfer.
3. Radiation,Electromagnetic. Step outside on a sunny day and feel the sun's rays on your face. You are feeling radiant heat transfer.

What actually goes on inside a wall assembly is complicated: there are air movements, ~ currents and capillary actions as well as vapour diffusion, and some materials have the capacity to absorb moisture whilst others provide a condensation surface.

I have a microwave, coffee maker, electric kettle, slow cooker, food processor, stick blender, ~ oven, and blender out on my countertops because I use them so often and I have no cupboard space to hold them.
