In our project a absorption chiller will be used to cover part of the cooling load. The chiller will run on lithium bromide / water solution. In this case, water is the refrigerant.
Water is a natural refrigerant with GWP, but my feeling says in the LEED Online form GWP and ODP should be set to 0. As far as I know the water content in the atmosphere depends on temperature mainly and not on water vapour released by humans.
Any hints or comments?
