A structure or media from which heat can be absorbed or extracted.
A device or media that absorbs heat for storage for later use.
The amount of heat that a material can absorb and store.
The flow of heat from one area to another by conduction, convection, and/or radiation. Heat flows naturally from a warmer to a cooler material or space.
A gas or liquid used to move heat energy from one place to another; a refrigerant.
Any coefficient used to calculate heat transmission by conduction, convection, or radiation through materials or structures.
That portion of the base metal that was not melted during brazing, cutting, or welding, but whose microstructure and mechanical properties were altered by the heat; Refers to area adjacent to a weld where the thermal cycle has coused microstructural chang ...
The quantity of heat necessary to raise the temperature of a specific mass of a substance by one degree.
The number of degrees per day that the daily average temperature (the mean of the maximum and minimum recorded temperatures) is below a base temperature, usually 65 degrees Fahrenheit, unless otherwise specified; used to determine indoor space heating req ...
Standardized weights or volumes for heating fuels.
Any gaseous, liquid, or solid fuel used for indoor space heating.
The rate of heat flow required to maintain a specific indoor temperature; usually measured in Btu per hour.
The coldest months of the year; months where average daily temperatures fall below 65 degrees Fahrenheit creating demand for indoor space heating.
The measure of seasonal or annual efficiency of a heat pump operating in the heating mode. It takes into account the variations in temperature that can occur within a season and is the average number of Btu of heat delivered for every watt-hour of electri ...
The amount of heat produced from the complete combustion of a unit of fuel. The higher (or gross) heating value is that when all products of combustion are cooled to the pre-combustion temperature, water vapor formed during combustion is condensed, and ne ...
All the components of the appliance used to condition interior air of a building.
Heatless reactivated dryer. By means of expanding cold dry air to near atmospheric pressure inside the regeneration tower, the dryer air picks up moisture from the saturated desiccant bed and is then purged to atmosphere.
To revolve the drum of a capstan, winch or windlass. (Pulling with mechanical deck heaving gear).
An order to haul away or to heave around a capstan (pull).
