... The maps are based on updated global databases for heat flow and crustal structure. For continental regions the estimates of lithospheric thickness are based on determinations of subcrustal heat flow, after corrections for contributions of radiogenic heat in crustal layers. For oceanic regions the e ...

... The predominant mode of heat transfer is assumed to be by conduction. This is not because we believe that the transfer of heat by fluids is always negligible, but because it seems that there are enough cases in which this does not dominate, on the length and time scales of heat transfer that are inv ...

In the absence of specific regulations or codes that require otherwise, a suggested guideline is to design all new hydronic heating systems so that they can provide design load heat output using a supply water temperature no higher than 120ºF. Even l ...

To improve consistency between different furnaces, plate thermometers were introduced to measure the heat flux to which samples are exposed. The use of plate thermometers means the EN fire resista ...

... Liquid saturation is zero at the inner radius of the heat pipe and slightly higher than the initial value of 0.8 at the outer radius, indicating that water boils off at one end and vapor is deposited at the other. This coincides with the significant gas flux of about 540 mm/yr in the outward directi ...

... Convection. Convection is the transfer of heat energy between a surface and a gas or liquid. In addition to simple temperature gradient, the rate of motion of the gas (air movement) or liquid (water) and its relative heat storage capacity will affect the rate of energy transfer. However, the compens ...

ASHRAE 55

ANSI/ASHRAE Standard 55 (Thermal Environmental Conditions for Human Occupancy) is a standard that provides minimum requirements for acceptable thermal indoor environments. It establishes the ranges of indoor environmental conditions that are acceptable to achieve thermal comfort for occupants. It was first published in 1966, and since 2004 has been updated periodically by an ASHRAE technical committee composed of industry experts. The most recent version of the standard was published in 2013.
