Abstract

Capillary gravity circulation cabinet is an air-conditioning terminal that integrates dehumidification, refrigeration, and heating functions. It was invented in Germany is now being applied in some office buildings in China. In this paper, the temperature field of the gravity circulation cabinet in different water supply temperature, water supply flow and room temperature under cooling and heating conditions is simulated and analyzed, and the proportion of radiation and convection in cooling and heating capacity is analyzed. The research shows that the water supply temperature has the greatest influence on the output of gravity circulation cabinet, water supply flow has little effect on the output of gravity circulation cabinet. When the indoor ambient temperature changes, the gravity cabinet has the ability of self-balance to the room temperature which can increase or decrease the heat exchange. The cooling or heating output of radiation mechanism accounts for about 10% of the output of the gravity circulation cabinet.
