Thermal efficiency means the useful electric energy output of a facility, plus the useful thermal energy output of the facility, expressed as a percentage of the total energy input to the facility.

Thermal efficiency of a pool heater means a measure of the percentage of heat from the input that is transferred to the water, as determined using the applicable test method in Section 1604(g).

Examples of Thermal efficiency in a sentence

Key Assumptions: • Et Base: Thermal efficiency of a standard commercial electric water heater: 98% • COP of an ASHP water heater: 3.5 • Cost estimates include installation.
According to test conditions, different efficiency characteristics can be investigated: o Peak optical efficiency at near perpendicular incidence of solar irradiance on the collector aperture and mean fluid temperature near ambient temperature eliminating both angular dependent effects as well a thermal loss, o Thermal efficiency at normal incidence for a range of operating temperatures.
Thermal efficiency, temperature distribution, and pressure drop were measured in relevant operating conditions of heat transfer fluid flow and high radiation fluxes (TRL3-4).
Thermal efficiency % or energy factor rating Tank or tankless Water heater input # e.g. ABC Corp.

More Definitions of Thermal efficiency

Thermal efficiency of a water heater means a measure of the percentage of heat from the combustion of gas or oil that is transferred to the water, as determined using the applicable test method in Section 1604(f).

Thermal efficiency of a space heater means a measure of the percentage of heat from the combustion of gas or oil that is transferred to the space being heated, or in the case of a boiler, to the hot water or steam, as determined using the applicable test methods in section 1604(e) of this Article. Thermal efficiency of a commercial warm air furnace equals 100 percent minus percent flue loss, as determined using test procedures prescribed under 10 C.F.R. section 431.76.

Thermal efficiency. (ηt) of a HRS means the ratio of the supply air temperature gain and the exhaust air temperature loss, both with respect of the outdoor

Thermal efficiency means the useful electricity output of an electric generating unit, plus the useful thermal energy output of the electric generating unit, expressed as a percentage of the total heat input to the electric generating unit. For purposes of N.J.A.C. 7:27D-3, thermal efficiency is based on the lower heating value of the fuel used by an electric generating unit.

Thermal efficiency means the ratio of useable heat energy output to energy input. The thermal efficiency must be calculated in accordance with:

Thermal efficiency. (ηt) of a HRS means the ratio of the supply air temperature gain and the exhaust air temperature loss, both with respect of the outdoor temperature, measured under dry reference conditions and with balanced mass flow ;
