Description of the Related Art As a combined hot water heating system, a hot water heated by a heat exchanger having a burner is supplied to an indoor heater and a floor heating panel, respectively, from the heat exchanger to the indoor heater and the floor heating. There is one that forms a hot water circulation circuit branched into a panel. In such a combined hot water heating system, the floor heating panel heats by radiating heat from the hot water circulating inside, and in the indoor heater, the indoor air is applied to the heating heat exchanger by the convection fan provided in the indoor heater. Thus, the indoor air is heated by the heat of the hot water that has passed through the indoor unit for heating, and is forced into the room as warm air. In addition, the temperature control of the room temperature in the combined hot water heating system is performed by hot water flowing out from the heat exchanger heated by the burner or the like according to the temperature difference between the set temperature set by the remote controller and the room temperature detected by the room temperature sensor. The target hot water temperature is determined, and the burner combustion amount is controlled while the temperature of the hot water flowing out from the heat exchanger is detected by the thermistor so that the hot water temperature becomes the determined target hot water temperature.

A hot keep operation is performed to heat only. In this hot-keeping operation, the convection fan stop time and operation time are set according to the temperature difference between the room temperature and the set temperature, and after the convection fan operation stops for the set stop time, The convection fan will automatically reactivate for the set operating time as well. At the end of re-operation of the convection fan, the indoor temperature is detected again, temperature control is performed according to the temperature difference between the detected indoor temperature and the set temperature, and if the room temperature is lower than the set temperature. , If the indoor unit is heating with the heating capacity according to the temperature difference and the room temperature is still higher than the set temperature,
The convection fan stop time and operation time are set again,
After that, similarly, the convection fan is repeatedly stopped and operated according to the temperature difference between the indoor temperature and the set temperature.

If the temperature difference between the set temperature and the room temperature is + 2.0 ° C. or more, the stop time is set to 8 minutes and the operation time is set to 5 minutes. On the other hand, during the hot-keeping operation in which the convection fan of the indoor heater is stopped, the temperature of the hot water heated by the heat exchanger becomes a constant temperature (for example, 47 ° C) suitable for supplying to the floor heating panel. In addition, the combustion amount of the burner is controlled.

れるという問題がある。As described above, in the conventional combined hot water heating system, in the hot keep operation performed when the room temperature becomes sufficiently higher than the set temperature, the stop time of the convection fan is reduced. However, depending on the temperature difference between the set temperature and the indoor temperature, it is only selected from two types of 3 minutes or 8 minutes, so while the convection fan is stopped and heating by the indoor heater is stopped. The room temperature may drop significantly, the room temperature may rise again after the convection fan restarts, and the room temperature may change significantly.The convection fan is selected according to the temperature difference between the set temperature and the room temperature. Since the maximum stop time is 8 minutes, if the indoor heater is continuously used for the next 5 minutes, for example, if the outside air temperature is high and the heating load is small. Because the floor heating panel continues to dissipate heat even when the convection fan is off, the room temperature does not drop to the set temperature even after the convection fan is off, and the convection flow continues. When the operation of the fan is restarted, the indoor temperature further rises, and when this is repeated, the indoor temperature gradually rises, and there is a problem that comfort is greatly impaired.

Room temperature setting device for
A room temperature sensor for detecting an indoor temperature, an outside air temperature sensor for detecting an outside air temperature, and a detection room temperature of the room temperature sensor for suspending heating by the indoor heater when the room temperature is higher than the target room temperature of the room temperature setting device. A pause time is determined based on the outside air temperature detected by the outside air temperature sensor, the outside air temperature is shorter as the outside air temperature is lower, and longer than the outside temperature, and the detected room temperature is lower than the target room temperature, When heating is performed by the indoor heater, and the detected room temperature is higher than the target room temperature, the heating by the indoor heater is suspended for the rest time determined by the rest time determining means, and after the rest time elapses, And an indoor heater control means for forcibly restarting heating by the indoor heater.

る。While the room temperature detected by the room temperature sensor is lower than the target room temperature of the room temperature setting device, the room heater operates to heat the room air. When the room temperature rises and the detected room temperature becomes higher than the target room temperature, the lower the outside air temperature is, the shorter the longer the rest time is based on the outside air temperature, and the longer the rest time is determined. However, the heating by the floor heating panel is continued even while the indoor heater is at rest. During the downtime, after the room heater is off,
Since the indoor heater is forcibly restarted to heat the room, the indoor temperature rises again due to the restart of the indoor heater.

るようにする。The down time determined by the down time determining means based on the outside air temperature is a time for stopping the indoor heater when the detected room temperature becomes higher than the set room temperature. When the temperature is low, the rest time is shortened regardless of the detected room temperature, and when the outside air temperature is not so low, the lower the detected room temperature is, the shorter the higher the room temperature is determined, and the longer the outside air temperature is determined. In this case, a longer rest time should be decided regardless of the detected room temperature.

のまま室内暖房機の作動が再開されることがない。When the outside air temperature is low and the heating load is large, the indoor temperature rises slowly even when the indoor heater operates, and the indoor temperature drops rapidly when the room is stopped. When the rest time is determined to be short, the width of the decrease in the room temperature during the rest time can be reduced, and the indoor heater can be re-activated before the room temperature drops much below the target room temperature. Conversely, when the outside air temperature is high and the heating load is small, the decrease in the room temperature when the indoor heater is stopped is slow, and when the indoor heater operates, the indoor temperature rises quickly. Even if the room temperature decreases due to the downtime, the floor heating panel continues to heat the room, so that the room temperature does not uncomfortably decrease too much, and the room temperature can be quickly raised with the operation of the room heater. Therefore, by determining the rest time to be long, the room temperature can be sufficiently reduced during the rest time, and the operation of the indoor heater can be restarted while the room temperature is higher than the target room temperature.

The hot water temperature is determined based on the temperature difference between the target room temperature and the detected room temperature, and the heating amount of the heating means is controlled so that the hot water temperature reaches the determined hot water temperature. On the contrary, while the indoor temperature rises, the detected room temperature becomes higher than the target room temperature, and the operation of the indoor heater is stopped, the target hot water temperature of the hot water flowing out of the heating heat exchanger is It is determined based on the outside air temperature detected by the temperature sensor.

On the contrary, when the outside air temperature is high and the heating load is small, the target hot water temperature can be determined to be low according to the outside air temperature. As a result, when the heating load is large, the hot water heated to a high temperature is supplied to the floor heating panel even when the room temperature is once higher than the target room temperature and the heating of the room heater is stopped. Therefore, the decrease in the indoor temperature can be moderated, and the comfortable state can be maintained for a long time. Also, when the heating load is small, the temperature of the hot water supplied to the floor heating panel is lowered after the room temperature once rises above the target room temperature and the heating of the indoor heater is stopped. The panel does not overheat the indoor air, and the comfortable state is less likely to be impaired.

くなる。This hot-keeping operation suspends the heating operation by the indoor unit 2 and heats only by the floor heating panel 3, and since the heating capacity becomes small, the indoor temperature is reduced while the indoor unit 2 is at rest. Is reduced. However, the rate of decrease of the indoor temperature during the rest of the indoor unit 2 is not uniform,
Depending on the heating load such as the difference in the outside air temperature Ta, when the heating load is large, the indoor temperature tends to decrease while the indoor unit 2 is at rest, and conversely, when the heating load is small, the indoor unit 2 It is difficult for the room temperature to drop during rest. Looking at this during heating of the indoor unit 2, even if the indoor unit 2 is similarly heated, the degree of increase in the indoor temperature becomes small when the heating load is large, and When the heating load is small, the degree of increase in the room temperature increases.

キープ動作時間ｔｓを決定するようにする。Therefore, in the present invention, the hot keeping operation time ts is determined based on the detected room temperature Tr and the outside air temperature Ta detected by the outside air temperature thermistor 404. The hotkeeping operation time ts determined based on the detected room temperature Tr and the outside air temperature Ta is the time for suspending the heating by the indoor heater 2 when the detected room temperature Tr becomes higher than the set room temperature Tset. For example, when the outside air temperature Ta is extremely low, the hotkeeping operation time ts is shortened regardless of the detected room temperature Tr, and when the outside air temperature Ta is not so low, the shorter the detected room temperature Tr becomes, the shorter the detected room temperature Tr becomes. The higher the temperature is, the longer the temperature is determined, and when the outside air temperature Ta is relatively high, the longer hot-keeping operation time ts is determined regardless of the detected room temperature Tr.

る。When the outside air temperature Ta is low and the heating load is large, the indoor temperature rises slowly even when the indoor heater 2 is activated, and the indoor temperature drops rapidly when the room is stopped. In this case, when the hot-keeping operation time ts is determined to be short, the width of the decrease in the indoor temperature during the suspension of heating of the indoor heating device 2 can be reduced by the hot-keeping operation,
The heating by the indoor heater 2 can be restarted while the room temperature does not drop much below the target room temperature Tset.

が再開されることがない。On the contrary, when the outside air temperature Ta is high and the heating load is small, the decrease in the room temperature when the room heater 2 is stopped is slow, and when the room heater 2 operates, the room temperature rises quickly. Therefore, even if the room temperature drops due to the slightly longer hot-keeping operation time ts, the heating by the floor heating panel 3 is continued, so the temperature does not uncomfortably drop too much, and the room heater 2 is restarted. The room temperature can be raised quickly. Therefore, by determining the hot-keeping operation time ts to be long, it is possible to sufficiently reduce the indoor temperature while the heating of the indoor heater 2 is stopped during the hot-keeping operation time, and the indoor temperature is lower than the target room temperature Tset. The operation of the indoor heater 2 will not be restarted in the high state.

の一例を表３に示す。On the other hand, during the hot-keeping operation, the detected room temperature Tr is sufficiently higher than the target room temperature Tset, and a large heating amount for the room is unnecessary. Therefore, during the hot keep operation in which the operation of the convection fan 200 is stopped, the target hot water temperature TO of the hot water heated by the heating heat exchanger 12 is set to the set temperature Tse of the remote controller 4.
It is determined based on the outside air temperature Ta detected by the outside air temperature thermistor 404, regardless of t and the room temperature Tr of the room temperature thermistor 405. In the present embodiment, the data of the target hot water temperature TO preset corresponding to the outside air temperature Ta is stored in the memory of the microcomputer, and when the outside air temperature Ta detected by the outside air temperature thermistor 404 is given, the temperature is The target hot water temperature TO corresponding to is determined.

For example, when the outside air temperature Ta is 0 ° C. or lower, the target hot water temperature TO is determined to be 70 ° C., and when it is 20 ° C. or higher, the target hot water temperature TO is determined to be 40 ° C. Since hot water of a constant temperature is not supplied to the floor heating panel 3,
A heating capacity suitable for the heating load for each time period can be obtained.

The room temperature thermistor 403 provided inside 2 cannot correctly detect the room temperature. Therefore, in the present embodiment, after the hot-keeping operation is completed, the convection fan 200 is forcibly operated for a fixed time tx (for example, 5 minutes) to radiate heat inside the indoor unit 2,
It is designed to detect the correct indoor temperature. Therefore, even if the hot-keeping operation is completed, the fixed time tx (5

The operation of the convection fan 200 is stopped for a new hotkeeping operation time ts determined by the above.
When the detected room temperature Tr is lower than the target room temperature Tset, temperature control is performed again thereafter by the detected room temperature Tr detected by the room temperature thermistor 403 and the target room temperature Tset by the remote controller 4.
