Title:
Heat source machine
Document Type and Number:
Japanese Patent JP6037158
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a heat source machine capable of preventing large undershooting where hot water much lower in temperature than a target temperature is supplied during the switching operation of a combustion region.SOLUTION: A heat source machine has a plurality of combustion regions where flames can be individually formed and is capable of switching between the increase and the decrease of combustion regions by appropriately switching the state of forming a flame in each combustion region and the state of forming no flame. An operation between switchings is executed when the combustion region is switched. The operation between switchings is executed on condition that switching from a state where a flame is formed in a downstream side combustion region located on the entire liquid flowing direction downstream side of a heat exchanger to a state where no flame is formed in the downstream side combustion region, and a stare where a flame is formed temporarily in the downstream side combustion region.
