In the previous paper (2007.1), we had suggested the calculation models to apply the Monte Carlo Simulation technique for hot and cold water demands in the guest rooms based on the measurement of fixture usage in a city hotel through one year. When we tried the calculation by using the model, it made some differences of the hourly values in the time series between the simulation and the measurement results. Therefore, in this paper, we presented the new calculation model on the frequency of each fixture usage in hourly patterns especially. The validity of the simulation technique was confirmed by comparison with the measurement results. According to the model of two persons occupied in a guest room, we calculated the hot and cold water demands in each scale of the number of guest rooms ; 50, 100, 200, 300 and 500 rooms. From these calculation results, we clarified that the instantaneous maximum flow rates per minute and per guest room were reduced on the increase of the number of guest rooms. Also, we analyzed the relationship between heating power and capacity of storage tank based on the calculation results of hot water demands every one minute through a day. From these results, we showed that the simulation method was very useful to promote energy conservation for hot water supply system.
