Abstract

This study evaluated the performance of a prototype air conditioning system. The configuration of the prototype was based on detailed simulation results performed as part of this study. The results of the previously completed simulation indicated that energy-efficient, properly-ventilated homes in humid climates need equipment options or configurations that can provide a modest amount of additional dehumidification capacity while coordinating their operation with conventional cooling and ventilation systems. A prototype air conditioning system was constructed using currently available components and provides a method to independently control sensible (temperature) and latent (moisture) building loads. The prototype system was tested in both a laboratory and field setting. Laboratory tests characterized the systems performance over a wide range of operating conditions. A follow-up field test investigated the system's ability to effectively control indoor temperature and relative humidity based on conventional thermostat and humidistat control.The study results indicate that this prototype air conditioner can effectively provide a comfortable indoor environment while maintaining a low first-cost and reasonable operating costs compared to other conventional equipment.
