Hi Jose,

I have tried to configure out the size and capacity of the hot water system
for apartments.

The result is that on the page 7-4 of ASHRAE users manual the calculations
have been given.

The snap-shot has been post -scripted after this statement:

[image: Inline image 1]

As per the curve one can bring about the hot water storage and recovery
capacity of the hot water cycle.

As in above example the number of units in the apartments is 80 so the 75
number has been chosen from the curve which is less than 80 and
the calculations have been done to bring  about the recovery capacity and
hot water storage.

The corresponding numbers have been chosen as per the curve chart and hence
the recovery capacity and usable storage has been found out.The 1.4 factor
has been considered as the consideration is 70% age useful storage capacity
of the tank.

The next page on User's manual i suppose is the efficiency of the hot water
system. This is the help from my side. Hope another comments may help you
may be more.

To whom it may concern:

What is the hot water use (gal/person/day) in residences according to the
ASHRAE manuals?  Any comments will be highly appreciated!

Kind regards,
