Packaged Terminal Heat Pump Assessment Study

摘要

A state-of-the-art assessment of packaged terminal heat pumps (PTHPs) is presented. Commercial heating, ventilating and air-conditioning (HVAC) market trends are reviewed as is the position of PTHPs in the commercial market. The features and operating characteristics of PTHPs are examined. A need for improving the low temperature heating performance of PTHPs is identified and concepts are presented for improvements in that area. Finally, research recommendations for enhancing PTHP performance are outlined.
