thermo-, therm-, thermi-, -thermia, -therm, -thermal, -thermic, -thermias, -thermies, -thermous, -thermy

The level of outdoor temperature at which the heating capacity of a heat pump matches the heating requirements of a building.

The speed limitation imposed on an aircraft by aerodynamic overheating.

1. A combination of thermal cells.
2. A voltage source consisting of a number of bimetallic junctions connected to produce a voltage when heated by a flame.
3. A high-temperature, molten-salt primary battery in which the electrolyte is a solid, non-conducting inorganic salt at ambient temperatures.d

When power is required, an internal pyrotechnic heat source is ignited to melt the solid electrolyte which allows electricity to be generated electrochemically for periods from a few seconds to an hour.

This process is often used for military applications; such as, missiles, torpedoes, and space missions.

1. A method that teaches patients to increase or to decrease the temperature of their hands by feedback with signals indicating hand temperature.

This has been used primarily in the treatment of headaches.

2. The monitoring of skin temperature as an index of blood flow changes because of the dilation and constriction of blood vessels, the feedback being displayed to the patient on a video monitor, accompanied by an audible signal.

It is used for stress management and in the treatment of hypertension, migraine, and Raynaud disease (usually a bilateral disease of the blood vessels; especially, of the extremities which might be caused by cold or emotion, accompanied by intermittent pallor, cyanosis, and redness, and generally accompanied by pain).

A floating foam cover that insulates well, but it does not allow light to pass through.

It is often used in swimming pools and spas.

A material of low heat conductivity placed between materials of higher conductance to reduce the flow of heat; for example, certain metal framed windows are designed with thermal breaks to improve their overall thermal performance.

1. Tissue reaction to or injury, usually of the skin, caused by exposure to extreme heat.
2. A burn caused by excessive heat or a type of injury to the skin caused by heat, electricity, chemicals, light, radiation, or friction.

The amount of heat which can be retained by a thermal storage.

The time rate of heat flow through a body (per unit area) from one of its bounding surfaces to the other for a unit temperature difference between the two surfaces, under steady conditions.

The ability of a system to conduct heat, usually measured in units of thermal conductance.

Vegetation of sufficient abundance and height to significantly ameliorate weather effects; such as, wind, heat, cold, and snow.

A refining process in which gas oils are subject to extreme temperatures under severe pressure, so that the molecules are cracked and broken into new molecules.

The time period between the energization of a heat-producing device and the measurable effect of the heat produced.

A process for the reduction of complex organic materials (usually biomass waste products) into light crude oil.

The removal of salt from seawater by condensing purified vapor to yield a product in the form of distilled water.
