Experiments on cooling capacity of capillary tube system

Presents the characteristics and classification of capillary tube cooling mode, and performs the experiments on cooling capacity of floor panel and ceiling capillary tube modes. As a result, the space adopting the two capillary tube modes can not be sufficiently cooled as designed under a maximum of cooling load (outside temperature 26 to 36 ℃) resulting in the condensation on panel surface while the two cooling methods can maintain the indoor design temperature without condensation under a normal cooling load(outside temperature 21 to 32 ℃) with operation of the dew-point control system.
