Practical simulation techniques for design of air conditioning appliances

The purpose of this paper is to illustrate how to develop suitable simulation techniques for the design of air conditioning appliances. Principles for development of practical simulation tools are proposed, i.e. model should be accurate, computation should be fast, and software operation should be convenient. Some simulation techniques that have been applied in product development are presented, including the simulation method for heat exchanger design and fin design, the steady-state simulation method for design of air conditioners, the dynamic simulation method for control strategy development of air conditioners, the fast calculation method for refrigerant thermodynamic properties, the simulation method for the thermal performance attenuation, and the intelligent simulation methods.
