Domestic hot water
Currently, I'm simulating an hotel which has a service hot water system. This
system is based in recovering heat of the superheated gas, which leaves
the compressor of an air cooled chiller, to heat the service hot water.
The following specification is detailed in Appendix G of ASHRAE
90.1-2007: "The service hot-water system in the baseline building design
shall use the same energy source as the corresponding system in the proposed
design and shall confirm with the following conditions..." Then, in item
b. there is the following information: "Where the energy source is
electricity, the heating method shall be electrical resistance."
So, should I model the baseline building with electrical resistance for
DHWDomestic hot water (DHW) is water used for food preparation, cleaning and sanitation and personal hygiene, but not heating. as in the proposed building the energy source is also electricity (consumed
by the chiller) ?
