Comment
Can you please clarify two items relative to Table 3 in Appendix
A:
1) When listing the evaporator temperature limits for chillers, is
this the temperature of the fluid being cooled or is it the bubble
point temperature of the refrigerant being evaporated in the
evaporator?
2) If a chiller is used as the upper stage heat rejection device of
a refrigeration system in a cold storage warehouse, would the
chiller's GWP limit be set by the chiller requirements or the lower
cold storage warehouse requirements?
