In some cases, such as Hospital operating rooms and Ice Rinks, you have to maintain indoor air dewpoint temperaturs lower than 44 F. To accomplish this, you typically have to use either a desiccant dehumidifier or a low-temp, glycol chiller, neither of which have a very high COP. However, Appendix G seems to only allow for the use of a 6.1 COP chiller supplying 44 F water to provide all cooling and dehumidification in the Baseline. Not only is it this physically impossible for the Baseline chiller to do, but if you allow the energy model to disregard the laws of physics, this tends to create a larger disadvantage for the Proposed design to overcome. So is there a more equitable way to have the Baseline provide dehumidification when the Proposed design must use something other than a traditional chiller?
