Abstract: Combined air-conditioner by heat pipe and compression applied in spaces requiring annual cooling has good energy saving potential. Three-port piston valve used for working mode switch of combined air-conditioner play an important role in running safely and reliably. A three-port piston valve applied for mode switch of combined air-conditioner by heat pipe and compression is introduced. Operating principle of three-port piston valve is elaborated. To simulate the dynamic characteristic of three-port piston valve,dynamic characteristic mathematics model of three-port piston valve is developed. The dynamic characteristic of switching mode is simulated, from comparison of simulation and test results:the simulation results and experimental results can be well identical, and the simulation model can be ensured to analyze the dynamic characteristic.
