Title:
熱媒循環式加熱装置
Document Type and Number:
Japanese Patent JP4493231
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To effectively utilize the residual-heat of an instantaneous heater after heating control is executed to improve the hot water/cold water heating efficiency of heating medium circulating type heating equipment. SOLUTION: The heating medium circulating type heating equipment is provided with the instantaneous heater 35 equipped with a heat exchanger 43, a gas burning burner 36, and an air supply fan 37 for a combustion chamber 44; a hot water/cold water circulating means E which circulates hot water/cold water between the heater 35 and heat-consuming terminals 1 and 2, and a heating control means C which controls the circulated flow rate of the hot water/cold water and the operation of the heater 35. When the supply of the hot water/cold water to the terminals 1 and 2 is demanded, the control means C controls the circulated flow rate of the hot water/cold water or the heating quantity by means of the heater 35 so that the hot water/cold water heating temperature by means of the heater 35 may become a target temperature. When the demand disappears, the control means C executes heating control for stopping the burning operation of the burner 37. When the control means C completes the execution of the heating control, the means C executes operation control for preventing post boiling by controlling the speed of rotation of the fan 37 so that the hot water/cold water staying in the heater 35 may be maintained at a set temperature.
