Abstract
First, the basic methodology for the system simulation was described. Second, relations between change in values measured by sensors and amount of heat supplied or potential energy supplied are described, which are generalizing many kinds of controlling methods. Third, difference between each thermal load (sensible, latent and fresh air volume) and amount of heat supplied by an air handling unit in change of each conditioned zone. Fourth, amount of supply heat in the various systems for heating and air-conditioning was studied, and then a general method for describing the systems including control systems was shown. Fifth, heat balance equations were made as basic equations. Sixth, related equations were arranged and described in Table 4, which included a system and a control method in case of solving the basic equations mentioned above for various definite systems. According to Table 4, various systems which are in common use can be described generally with control included. Seventh, relations between Table 4 and various definite systems were described. Eighth, using the related equations mentioned above, the outline of schematic calculation flow was described, which calculates defenitely various state values, an indoor environment level and heat exchanged. Finally, the examples of calculation using the simulation program made by the method described above was showed.
