Heat Pump with Dehumidification Mode of Operation


This article reviews the background and development of a split-type heat pump system with three operating modes: heating, cooling, and dehumidifying. An analytical method was developed to assess the effectiveness and operating cost of active dehumidification options. Several technologies were compared and contrasted using this evaluation tool. A split-system heat pump that flexibly controls both indoor temperature and humidity was built and tested. Laboratory and field performance results are discussed.
