<P>PROBLEM TO BE SOLVED: To accurately predict a solar heat collection amount at a low cost in operation control of a hybrid hot water supply machine 1. <P>SOLUTION: The hybrid hot water supply machine 1 predicts weather of the next day according to an atmospheric pressure detection value obtained by an atmospheric pressure sensor 14 and a heat collection amount performance value PQ of the day by a solar heat collection apparatus 3, and based on the predicted weather, finds a heat collection amount prediction value SQ of the next day by the solar heat collection apparatus 3. In this way, the heat collection amount performance value PQ in the past can be used for predicting weather, so that weather prediction accuracy can be improved by using both of the atmospheric pressure detection value and the heat collection amount performance value PQ in the past even when an atmospheric pressure transition pattern does not meet a few patterns having high weather prediction accuracy. Therefore, weather prediction accuracy can be improved by a method using an inexpensive atmospheric pressure sensor 15, and the solar heat collection amount can be predicted with high accuracy at a low cost in operation control of the hybrid hot water supply machine 1. <P>COPYRIGHT: (C)2008,JPO&INPIT |
