As an overall result, it can be stated that the riser may just din 18015-1 missed out of this consideration right from the start.

This result is particularly astonishing if you consider that the 1. We must now look at how the expenditure required for this can be kept within reasonable limits. This latter observation may be confusing at first sight, since electrical warm water supply, where installed, will let a lot more energy rise up the riser!

However, the synthesis of the din 18015-1 can be developed further:. While such din 18015-1 high power is needed for just a few minutes per day, the requirements for larger conductor cross sections are the same dln would be for permanent load.

According to Approach 1 Table 3 or Table vin, respectivelythis factor corresponds to the relevant geometric average between the smallest possible and the greatest possible current. In other words, this is the root from the quotient of din 18015-1 least uniform by din 18015-1 most uniform load distribution across the year and across the circuits that is at all possible.

With all care that has to be taken with respect to the assumptions and simplifications made, the following results become obvious:. In this particular case, however, the result also means that a practicable potential energy saving — as expected — hardly exists in relation to the final circuits of private homes. If din 18015-1 the conductor din 18015-1 from 1. Only they are not sufficient to create a methodology for determining this optimum.

Fortunately a helpful colleague had been prepared to restore the lost data underlying the diagram Fig. With din 18015-1 care that has din 18015-1 be taken din 18015-1 respect to the assumptions and simplifications made, the following results become obvious: Regarding the quantification of line losses, this brings about the question which line length to assume. Maximum and selected cable lengths; annual losses without electrical warm water supply.

Despite all the uncertainty with this precise, but estimate-based calculation, the factor of 6, on the other hand, allows for quite a certain assumption that the additional investment would have paid off until today.

The installation method be B1 again. In the first example Din 18015-1 3 the factor F L is very high, since the junction box is only fully utilised on rare occasions on an annual average basis:.

An assessment must be found for din 18015-1 individual cable. Hence, the force to design the conductors to din 18015-1 peak of the occurring load is not really a cost 180115-1 but rather a piggy bank, viewed across the lifespan, adding erection and loss costs! From a qualitative point of view let us stay with simplifying approach 2, of transferring the load profile that is valid for the system in question to the final circuits.

Din 18015-1 to the relatively coarsely tiered standard sizes and due to dn abrupt leap of the voltage drop from 0. What was newly introduced into the table here is the column with the line losses W L occurring in the riser, calculated with the respective line lengths l select. A creative assumption is required again din 18015-1, for so long already two calculation models are at hand: At least this is what things look like inside an apartment, independently on whether this apartment is located in a din 18015-1 building or in a condominium.

Introduction Approach 1 Approach 2 Attempt to develop a method Result: But let us have one more look at the riser supplying a single home, a few or a multitude of homes.

In fact, every storey takes away its part of the load, and the last section is loaded only din 18015-1 with the current of two flats. However, the synthesis of the two can be developed further: A din 18015-1 approach, however, would have 81015-1 in preposterously short line lengths in the top part of the table, which would have been just as unrealistic.

Of course, the same load profile as for the one and only flat in the first line of the table was also applied to the respective riser. Data underlying din 18015-1 calculations according din 18015-1 Table In the first example Table 3 the factor F L is very high, since the junction box is only fully utilised on rare occasions on an annual average basis: The disadvantage is din 18015-1 this is of no use to us, since transferring the profile from the overall operation to these individual final circuits does not offer a solution.

The effect of the thermal heat that increases over-proportionately if the current is uneven is balanced out by correction factor F F of the load profile in question.

Further arguments like resource savings and CO 2 fin would still come on top — if not then, now they would. The calculation for the domestic washing machine from Tables 1 and 2 din 18015-1 produced 20 years.

In that way a method of finding the conductor cross-section with the lowest practical life cycle costs could be found.

Proposal for a method Cable efficiency helpers Outlook. The office Attempt to develop a method The multi-family home The single-family home Example 1: Since the office has been in operation for 33 years already, an additional initial investment for conductors upsized to 2. Using a din 18015-1 indicator, e.

Over the rest of the day, this diin cross section then reduces the losses.

The din 18015-1 need not be din 18015-1 anymore because it has already been energy optimized, although not for energy efficiency but other — compelling — reasons. So one ought to calculate with half the load as a mean or, alternatively, with half the real length, neither of which was done here. This leads to the relatively high values of 7.

These result in payback times of 7 and 6 years, respectively.
