摘要：
The present study has been conducted to simulate dynamics of a gas engine-driven heat pump (GHp) for design of control algorithm. The dynamics modeling of a GHp was based on conservation laws of mass and energy. For automatic control of refrigerant pressures, actuators such as engine speed, outdoor fans, coolant three-way valves and liquid injection valves were pI or p controlled. The simulation results were found to be realistic enough to apply for control algorithm design. The model can be applied to build a virtual real-time GHp system so that it interfaces with a real controller in purpose of prototyping control algorithm.
