Cooling and heating season performance of an open counterflow heat-source tower heat pump system in high-humidity climates: An experimental and numerical study.

ABSTRACT: The cooling and heating season performance of an open counterflow heat-source tower heat pump (HTHP) system in high-humidity climates is investigated through an integrated experimental and numerical study, focusing on its year-round operation under typical conditions. The heat and mass transfer models for summer and winter were validated using measured data. Results show that increasing the inlet air temperature in summer enhances latent heat transfer by 25% but reduces sensible heat transfer by 31%. Raising the water temperature from 28.0 °C to 34.0 °C resulted in a 20.7% increase in latent heat transfer and a 16.7% decrease in sensible heat transfer, thereby increasing the latent heat ratio to 87.19%. In winter, increasing the inlet air temperature from -1.0 °C to 7.0 °C enhanced sensibl
