20100096467 | METHOD FOR CONTROLLING HEATING APPARATUS - An object of the present invention is to provide a method of controlling a heating apparatus that is capable of automatically controlling a heating-off temperature and a heating-on temperature according to an operation environment such that upper and lower variations of a room temperature set by a user are reduced on the basis of the room temperature, thereby allowing the user to feel comfortable. In order to achieve the object of the present invention, there is provided a method of controlling a heating apparatus that controls the start/stop operation of the heating apparatus on the basis of a room temperature set by a user. In this case, a temperature when the heating apparatus is operated to increase the room temperature and the operation of the heating apparatus is stopped is set as a temperature that is obtained by subtracting a heating-off temperature at a cycle immediately before a current cycle by a compensation value determined according to overshoot that has occurred at the cycle immediately before the current cycle, and a temperature when the operation of the heating apparatus is stopped to decrease the room temperature and the heating apparatus is operated is set as a temperature that is obtained by adding the heating-on temperature at the cycle immediately before the current cycle and a compensation value determined according to undershoot that has occurred at the cycle immediately before the current cycle, such that a difference between the measured room temperature and the room temperature set by the user is minimized. | 04-22-2010 |

20100258194 | METHOD FOR CONTROLLING HEATING SYSTEM - A method for controlling a heating system for uniformly heating respective rooms by proportionally calculating heat supplies required by the respective rooms, even when the heat supplies required for heating the respective rooms are different from each other, depending on indoor temperature conditions and external conditions of the respective rooms. The method adjusts flow rates of heating water supplied to the respective rooms by adjusting opening rates of room valves installed in heating water pipes. Current temperature differences between temperatures set for the respective rooms and indoor temperatures measured in the respective rooms are calculated, and opening rates of other room valves of other rooms, excluding rooms having a current temperature difference larger than a previously set temperature difference, are reduced. | 10-14-2010 |
20100270385 | METHOD FOR CONTROLLING HEATING SYSTEM - A method for controlling a heating system for organically controlling heating of respective rooms to uniformly heat the respective rooms by proportionally calculating heat supplies required by the respective rooms from temperature of returned water, even when the heat supplies required by the respective rooms are different from each other, depending on external conditions of the respective rooms. The method adjusts flow rates of heating water supplied to the respective rooms by adjusting opening rates of room valves installed in heating water pipes. The temperature of the returned heating water is measured, a ratio of opening rates of the respective room valves is calculated from the measured temperature of the returned water to proportionally supply heat to the respective rooms, and the opening rates of the respective room valves are adjusted, depending on the calculated ratio of the opening rates. | 10-28-2010 |
20100326372 | WATER HEATER HAVING A WATER LEAKAGE SENSING DEVICE - A water heater equipped with a leakage detecting device is provided. A flow control valve is disposed at an inlet and controls the flow rate of water flowing into the water heater. A leakage detecting device detects when water which has flowed in the water heater leaks out through pipes in the water heater due to burst of the pipes and is filled at or more than a predetermined level from the floor of a water heater case, and transmits a signal to a controller. A case protects parts in the water heater by shielding the parts from the outside. The controller controls a series of combustion processes and operation of the water heater, and closes the flow control valve, when a leakage detection signal is transmitted from the leakage detecting device. | 12-30-2010 |
20100326646 | METHOD FOR CONTROLLING A HOT WATER TEMPERATURE USING LOW FLUX IN HOT WATER SUPPLY SYSTEM - 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. | 12-30-2010 |
