METHOD FOR CONTROLLING A HOT WATER TEMPERATURE USING LOW FLUX IN HOT WATER SUPPLY SYSTEM
First Claim
1. A method of controlling temperature of hot water for using hot water at a low-flow rate in a hot water supply system, which includes:
- a flow sensor that measures the flow rate of water flowing into the hot water supply system;
a heat exchanger that transfers heat of a heating device to the water that has flowed inside;
a water tank that temporarily stores the water in the hot water supply system;
a temperature sensor that is disposed at a predetermined position in a pipe line through which the water flows;
a controller that has an input unit to allow a user to input desired conditions; and
a pump that is disposed in a pipe line connecting a first diverging point formed at a pipe line for an outlet and a second diverging point formed at a pipe line for an inlet, the method comprising;
measuring the flow rate of water flowing into the hot water supply system, using the flow sensor;
preheating-circulating water in the hot water supply system through an internal circulation path connecting the first diverging point, the second diverging point, and the heat exchanger, using the pump, after the controller stops the combustion of the heating device when the measured flow rate is an operation flow rate of the water supply system or less;
measuring the temperature of the water circulating, using the temperature sensor; and
setting predetermined temperature above user set-temperature as preheating circulation-off temperature and predetermined temperature below the set temperature as preheating circulation-on temperature, and then starting operation of the heating device when the temperature measured by the temperature sensor is preheating circulation-on temperature or less and stopping the operation of the heating device when the measured temperature is the preheating circulation-off temperature or more, using the controller.

Abstract
Provided is a method of controlling the temperature of hot water in a hot water supply system. The flow rate of water flowing into the hot water supply system is measured. Water is preheated/circulated through an internal circulation path connecting a first diverging point, a second diverging point, and a heat exchanger, after a controller stops the combustion of a heating device when the measured flow rate is an operation flow rate of the water supply system or less. The temperature of the water circulating is measured. Predetermined temperature is settled above user set-temperature as preheating circulation-off temperature and predetermined temperature is settled below the set temperature as preheating circulation-on temperature, and operation of the heating device is started when the temperature is the preheating circulation-on temperature or less, and the operation of the heating device is stopped when the measured temperature is the preheating circulation-off temperature or more.
