Simulation design based on state space for environment test equipment

To calculate the system capacity accurately in environment test equipment design, a simulation scheme is introduced. This scheme is based on distributed parameter model which is expressed in state space. In the traditional design, refrigeration of loading is regarded as completeness at the end of refrigeration course. As a result, the system capacity is calculated much greater than the actual need. Compared with traditional design, the simulation design scheme is more accurate in system capacity calculation. The simulation scheme can be applied to test and compare with different control scheme. It is of significant meaning in the initial design stage.
