A customer-defined code based on the following mathematic equations was programmed by MATLAB for simulating the thermal performances of the above four tri-generation systems. Firstly, the weather data, enthalpy of the flue gas, physical parameters of water, as well as the design parameters of each system were set as input for the system simulation. Then, the heating load was estimated before processing the corresponding simulation procedure for each system. The distribution of the flue gas or hot water was simulated thereafter according to different system's design. In the end, different energy utilization efficiencies can be obtained. Fig. 7 shows the simulation flow chart of the four tri-generation systems.
