Summary

The target of this study is to develop the high efficiency air conditioning system using water source heat pump units. The water source makeup air unit applied the desiccant rotor whose adsorption/desorption processes can work at low-temperature was developed for one kind of units on the high efficiency air conditioning system. This makeup air unit consisted of the refrigerant cycle, the water heat source line, and the desiccant rotor. A prototype makeup air unit was produced and its performance was tested. As results, the capacity was 4.84kW and COP was 4.78 under the cooling/dehumidifying operation at the heat sink water of 32°C, the inside air of 27°CDB / 19°CWB and the outside air of 33°CDB / 28°CWB. The capacity was 6.79kW and COP was 5.62 under the heating/humidifying operation at the heat source water of 25°C, the inside air of 22°CDB / 15°CWB and the outside air of 0°CDB / -3°CWB.
