ratio of two factors that have the same units, it has no units. And since the numerator is useful work (or heat equivalent), conservation measures that alter the useful work produced do not improve the efficiency. The formula itself is as simple as it can be: merely a ratio. The ...
For the SEER rating (Seasonal Energy Efficiency Ratio), we measure the EER rating for partial loads (at 25%, 50%, and 75% output) and full load (100% output) and then use a weighted-average calculation that, in most basic terms, presume the AC unit runs, on average, at 58% output...
5.1.5 BEYOND THE FACILITY Recall the energy efficiency formula from the beginning of this chapter: Efficiency = Computation Total Energy = ( P1UE) × ( 1 SPUE ) × (Total Energy Computation to Electronic Components ). (a) (b) (c) So far we've discussed the first term, facility over...
and this was a powerfuldisincentivetoenergy efficiency measures. There have been attempts to adjust the regulatory formula for the gas industry to generate funds for an Energy Saving Trust (EST). However, the new Director General of Gas Supply, Claire Spottiswoode, has frustrated attempts to impose...

For the integration in time of a discontinuous Galerkin approach it is natural to use the right-sided\((k+1)\)-point Gauss–Radau quadrature formula. On the subinterval\(I_n\), it reads as $$\begin{aligned} Q_n(w):= \frac{\tau _n}{2}\sum _{\mu =1}^{k+1} {\hat{\omega...
This work provides an empirical formula to calculate the FEPE for different detectors using the effective solid angle ratio derived from experimental measurements. The full energy peak efficiency (FEPE) curves of the (2??*2??) NaI(Tl) detector at different seven axial distances from the detector...
7.1 Total energy efficiency of interrupted SUs In this paper, we formulate the joint performance of interrupted SUs as the total energy efficiency, which is defined as the ratio of the sum rate and total power consumption of the interrupted SUs [20, 21], i.e., ηtot=RtotPtot (26) ...
Based on a formula explained in [25], the body surface area of the laboratory occupants is around 1.3 m2, and hence the calculated warmness formed by each occupant is 75.66 W [26]. The heat loss due to each laboratory apparatus is evaluated using Equation (9) with specifications obtained...
