Résumé

A novel frost-free air-source heat pump water heater applying dehumidification device and thermal storage on the basis of traditional system is studied in this paper. The operation mode of this system includes heating mode and regeneration mode. An experimental apparatus is built up to study this system, and according to the experiment,the frost-free operating time of this
system is 32 min, 34 min and 36min respectively when the temperature of air is -3°C, 0°C, 3°C and the relative humidity is
85%. And the temperature is high enough for the regeneration of desiccant, which could keep the heat pump heating water continuously. Besides, the COP of this system at temperature of -3°C and 3°C is 17.9% and 3.4% higher than the reverse cycle defrosting system in the same conditions, which proves that this new system has better performance under low environment temperature.
