As the heating and cooling load of a nearly zero energy building (NZEB) will be greatly reduced, significant energy saving effect can be obtained. In view of the low heating and cooling load and high human thermal comfort level of the NZEB, an air-conditioning terminal device based on natural heat transfer was brought out and studied by the authors. It has the functions of heating, cooling and moisture removal according to the inlet media temperature of the device. Also there is little noise or air disturbance during its operation, thus it is beneficial for the enhancement of human thermal comfort. In the paper, the experimental data of the heating and cooling performance of the device under different operation conditions were collected and analyzed. The calculation models quantifying its heating and cooling capacities were obtained through data regression analysis, and the flow resistance curve of the device was obtained by means of experimental measurement under various flow rates. In addition, comparison was made on the heating and cooling capacities between the device and the radiant floor which also features little noise or air disturbance, and it shows that the heating and cooling capacities of the device are 41.5 and 46.8% higher than the maximum capacities of the radiant floor respectively. The research lays a foundation for the engineering application of the natural heat transfer air-conditioning terminal device.
