This paper introduces an integrated system that can achieve the multi-functions with improved energy performance. This system, which is applicable for bathroom can run three different cycles and perform six modes. A series of theoretical investigations were conducted to develop a design criterion for the new systems. The rough cost estimate indicated to have good market prospect due to a little cost increase. A prototype of the system was tested in a national-standard laboratory under relative Chinese standard. The experimental results showed that the mean coefficient of performance for the system reaches 4.22 when it worked as heat pump water heater. Also its dehumidification capability reached 1.29L/h, higher than the limit of the standard of dehumidifier. It certainly achieved the heating/cooling capacity requested on the standard of room air conditioners and the energy efficiency ratio was 2.64.
