Abstract：In order to solve the problems of the waste in traditional air conditioning system energy of taste，when heat and moisture loadmainly by convection heat transfer to eliminate indoor，the capillary radiation heat transfer technology was investigated. After the analysisof undertaking indoor sensible heat load by capillary，but indoor latent load all by the fresh air system，the control method independent ofeach other between the air conditioning room temperature and humidity was established. A method of flow control method of variablechilled water was presented to solve the problem of capillary condensation heat transfer. Capillary radiation cooling system stop water tosupply when the fresh air system is running；but capillary radiation cooling system water resupply after the fresh air dehumidificationsystem. The intermittent flow control scheme about radiation cooling system capillary were evaluated on this basis. The experimentalresults show that the control scheme is not only simple but also energy saving.
