Can ASHRAE Standard 62-1989 Requirements be Satisfied while Maintaining Moisture Control using Stock HVAC Equipment in Hot, Humid Climates?
Abstract
Outdoor air intake rates are studied to
determine their impacts on moisture control
in buildings, especially in hot, humid
climates. Key impacts of outdoor air intake
rates can be readily modeled and studied
using computer simulations of building
energy costs. Increased ventilation rates
create real capital and operating costs for
building owners and operators, with
implications beyond energy costs relating to
increased ventilation requirements. In hot,
humid climates, increased ventilation rates
increase latent loads more than sensible
loads, requiring lower sensible heat ratios.
Stock HVAC package units and split systems
are not available with the requisite sensible
heat ratios, and cannot maintain moisture
control in small commercial buildings
without costly modifications.
