Direct-Expansion Air-Conditioning System Performance in Low Humidity Applications: A Case Study
Abstract
This paper discusses the performance
of an HVAC system to maintain temperature
and humidity within a candy storage
warehouse. The HVAC system consists of a
typical direct-expansion cooling and
dehumidification coil and electric
resistance reheaters. Historic energy-use
data and field-measured performance data
are analyzed. The importance of certain
design and operating parameters such as
indoor airflow quantity, cooling coil
apparatus dew-point temperature and the
air-handling unit's fan operating strategy
on the dehumidification performance of the
HVAC system are discussed and analyzed. It
also offers recommendations for design and
operation of such systems.
